0 | 41 |
278 | 42 This file is rather large, but we have tried to sort the entries by |
43 their respective relevance for XEmacs, but may have not succeeded | |
44 completely in that task. The file is divided into four parts: | |
124 | 45 |
197 | 46 - Problems with building XEmacs |
47 - Problems with running XEmacs | |
48 - Compatibility problems | |
49 - Mule issues | |
120 | 50 |
197 | 51 Use `C-c C-f' to move to the next equal level of outline, and |
223 | 52 `C-c C-b' to move to previous equal level. `C-h m' will give more |
53 info about the Outline mode. | |
120 | 54 |
197 | 55 Also, Try finding the things you need using one of the search commands |
56 XEmacs provides (e.g. `C-s'). | |
57 | |
524 | 58 General advice: |
957 | 59 |
524 | 60 WATCH OUT for your init file! (~/.xemacs/init.el or ~/.emacs) If |
61 you observe strange problems, invoke XEmacs with the `-vanilla' | |
62 option and see if you can repeat the problem. | |
197 | 63 |
957 | 64 Note that most of the problems described here manifest at RUN |
65 time, even those described as BUILD problems. It is quite unusual | |
66 for a released XEmacs to fail to build. So a "build problem" | |
67 requires you to tweak the build environment, then rebuild XEmacs. | |
68 A "runtime problem" is one that can be fixed by proper | |
69 configuration of the existing build. Compatibility problems and | |
70 Mule issues are generally runtime problems, but are treated | |
71 separately for convenience. | |
72 | |
120 | 73 |
124 | 74 * Problems with building XEmacs |
197 | 75 =============================== |
0 | 76 |
373 | 77 ** General |
1245 | 78 |
915 | 79 Much general information is in INSTALL. If it's covered in |
80 INSTALL, we don't repeat it here. | |
81 | |
3404 | 82 *** X11/bitmaps/gray (or other X11-related file) not found. |
83 | |
84 The X11R6 distribution was monolithic, but the X11R7 distribution is | |
85 much more modular. Many OS distributions omit these bitmaps (assuming | |
86 nobody uses them, evidently). Your OS distribution should have a | |
87 developer's package containing these files, probably with a name | |
88 containing the string "bitmap". Known package names (you may need to | |
89 add an extension such as .deb or .rpm) include x11/xbitmaps (Ubuntu) | |
90 and xorg-x11-xbitmaps (Fedora Core 5). | |
91 | |
1098 | 92 *** How do I configure to get the buffer tabs/progress bars? |
915 | 93 |
94 These features depend on support for "native widgets". Use the | |

95 --with-widgets option to configure. Configuration of widgets is |
915 | 96 automatic for "modern" toolkits (MS Windows, GTK, and Motif), but if |
97 you are using Xt and the Athena widgets, you will probably want to | |
98 specify a "3d" widget set. See configure --usage, and don't forget to | |
99 install the corresponding development libraries. | |
100 | |
101 *** I know I have libfoo installed, but configure doesn't find it. | |
102 | |
103 Typical of Linux systems with package managers. To link with a shared | |
104 library, you only need the shared library. To compile objects that | |
105 link with it, you need the headers---and distros don't provide them with | |
106 the libraries. You need the additional "development" package, too. | |
107 | |
373 | 108 *** When using gcc, you get the error message "undefined symbol __fixunsdfsi". |
109 When using gcc, you get the error message "undefined symbol __main". | |
110 | |
111 This means that you need to link with the gcc library. It may be called | |
112 "gcc-gnulib" or "libgcc.a"; figure out where it is, and define LIB_GCC in | |
113 config.h to point to it. | |
114 | |
115 It may also work to use the GCC version of `ld' instead of the standard one. | |
116 | |
117 *** Excessive optimization with pgcc can break XEmacs | |
124 | 118 |
119 It has been reported on some systems that compiling with -O6 can lead | |
120 to XEmacs failures. The workaround is to use a lower optimization | |
121 level. -O2 and -O4 have been tested extensively. | |
122 | |
229 | 123 All of this depends heavily on the version of pgcc and the version |
124 of libc. Snapshots near the release of pgcc-1.0 have been tested | |
125 extensively and no sign of breakage has been seen on systems using | |
126 glibc-2. | |
127 | |
373 | 128 *** src/Makefile and lib-src/Makefile are truncated--most of the file missing. |
229 | 129 |
373 | 130 This can happen if configure uses GNU sed version 2.03. That version |
131 had a bug. GNU sed version 2.05 works properly. | |
124 | 132 |
373 | 133 *** When compiling with X11, you get "undefined symbol _XtStrings". |
124 | 134 |
373 | 135 This means that you are trying to link emacs against the X11r4 version of |
136 libXt.a, but you have compiled either Emacs or the code in the lwlib | |
137 subdirectory with the X11r5 header files. That doesn't work. | |
124 | 138 |
373 | 139 Remember, you can't compile lwlib for r4 and emacs for r5, or vice versa. |
140 They must be in sync. | |
124 | 141 |
373 | 142 *** test-distrib says that the distribution has been clobbered |
197 | 143 or, temacs prints "Command key out of range 0-127" |
144 or, temacs runs and dumps xemacs, but xemacs totally fails to work. | |
145 or, temacs gets errors dumping xemacs | |
146 | |
147 This can be because the .elc files have been garbled. Do not be | |
148 fooled by the fact that most of a .elc file is text: these are binary | |
149 files and can contain all 256 byte values. | |
150 | |
151 In particular `shar' cannot be used for transmitting GNU Emacs. It | |
152 typically truncates "lines". (this does not apply to GNU shar, which | |
153 uses uuencode to encode binary files.) | |
154 | |
155 If you have a copy of Emacs that has been damaged in its nonprinting | |
156 characters, you can fix them by running: | |
157 | |
158 make all-elc | |
159 | |
160 This will rebuild all the needed .elc files. | |
161 | |
1318 | 162 ** Intel Architecture General |
163 | |
164 *** Don't use -O2 or -O3 with Cygwin 1.0, CodeFusion-99070 or gcc 2.7.2 on x86 | |
165 without also using `-fno-strength-reduce'. | |
166 | |
167 gcc will generate incorrect code otherwise. This bug is present in at | |
168 least 2.6.x and 2.7.[0-2]. This bug has been fixed in GCC 2.7.2.1 and | |
169 later. This bug is O/S independent, but is limited to x86 architectures. | |
170 | |
171 This problem is known to be fixed in egcs (or pgcc) 1.0 or later. | |
172 | |
173 Unfortunately, later releases of Cygnus-released compilers (not the | |
174 Net-released ones) have a bug with the same `problem signature'. | |
175 | |
176 If you're lucky, you'll get an error while compiling that looks like: | |
177 | |
178 event-stream.c:3189: internal error--unrecognizable insn: | |
179 (insn 256 14 15 (set (reg/v:SI 24) | |
180 (minus:SI (reg/v:SI 25) | |
181 (const_int 2))) -1 (insn_list 11 (nil)) | |
182 (nil)) | |
183 0 0 [main] | |
184 | |
185 If you're unlucky, your code will simply execute incorrectly. | |
186 | |
187 *** Don't use -O2 with gcc 2.7.2 under Intel architectures without also | |
188 using `-fno-caller-saves'. | |
189 | |
190 gcc will generate incorrect code otherwise. This bug is still | |
191 present in gcc 2.7.2.3. There have been no reports to indicate the | |
192 bug is present in egcs 1.0 (or pgcc 1.0) or later. This bug is O/S | |
193 independent, but limited to x86 architectures. | |
194 | |
195 This problem is known to be fixed in egcs (or pgcc) 1.0 or later. | |
196 | |
373 | 197 *** `compress' and `uncompress' not found and XFree86 |
198 | |
199 XFree86 installs a very old version of libz.a by default ahead of where | |
200 more modern version of libz might be installed. This will cause problems | |
201 when attempting to link against libMagick. The fix is to remove the old | |
202 libz.a in the X11 binary directory. | |
203 | |
204 | |
3863 | 205 ** X11 and Motif |
1245 | 206 |
207 Motif is the X11 version of the Gnus torture test: if there's a way to | |
208 crash, Motif will find it. With the open source release of Motif, it | |
209 seems like a good idea to collect all Motif-related issues in one | |
3863 | 210 place. X11 itself is not all that safe, either. |
211 | |
212 You should also look in your OS's section, as it may not be the window | |
213 system (toolkit's) fault. | |
214 | |
215 *** XEmacs and the X server crash when inserting or displaying a TAB character. | |
216 | |
217 If you are using the XFree86 distribution, you need an X server with | |
218 this patch applied: | |
219 | |
220 https://bugs.freedesktop.org/attachment.cgi?id=2016 | |
221 | |
222 Versions of XFree86 previous to that crashed when an app tried to draw a | |
223 literal tab character using many fonts. | |
1245 | 224 |
225 *** XEmacs crashes on exit (#1). | |
226 | |
227 The backtrace is something like: | |
228 | |

249 This is known to happen with Lesstif version 0.93.36. Similar | |
250 backtraces have also been observed on HP/UX and Solaris. There is a | |
251 patch for Lesstif. (This is not a solution; it just stops the crash. | |
252 It may or may not be harmless, but "it works for the author".) | |
253 | |
254 Note that this backtrace looks a lot like the one in the next item. | |
255 However, this one is invulnerable to the Solaris patches mentioned there. | |

303 Marcus Thiessel <marcus@xemacs.org> | |
304 | |
305 Unfortunately, XEmacs releases prior to 21.0 don't work with | |
306 Motif2.1. It will compile but you will get excessive X11 errors like | |
307 | |
308 xemacs: X Error of failed request: BadGC (invalid GC parameter) | |
309 | |
310 and finally XEmacs gets killed. A workaround is to use the | |
311 Motif1.2_R6 libraries. You can the following line to your call to | |
312 configure: | |
313 | |
314 --x-libraries="/usr/lib/Motif1.2_R6 -L/usr/lib/X11R6" | |

326 | |
327 This is a bug. Please apply the patch PHSS_19964 (check if | |

1009 | 342 *** IBM compiler fails: "The character # is not a valid C source character." |
343 | |
344 Most recently observed in 21.5.9, due to USE_KKCC ifdefs (they just | |
345 happen to tickle the implementation). | |
346 | |
347 Valdis Kletnieks says: | |
348 | |
349 The problem is that IBM defines a *MACRO* called 'memcpy', and we | |
350 have stuck a #ifdef/#endif inside the macro call. As a workaround, | |
351 try adding '-U__STR__' to your CFLAGS - this will cause string.h to | |
352 not do a #define for strcpy() to __strcpy() - it uses this for | |
353 automatic inlining support. | |
354 | |
355 (For the record, the same issue affects a number of other functions | |
356 defined in string.h - basically anything the compiler knows how to | |
357 inline.) | |

366 ABSTRACT: | |
367 <IX89470>: LIBXT.A INCORRECT HANDLING OF EXCEPTIONS IN XTAPPADDINPUT | |

375 | |
376 This means your system was installed with only the X11 runtime i.d | |

383 | |
384 This is a problem in libIM.a. You can work around it by executing | |
385 these shell commands in the src subdirectory of the directory where | |
386 you build Emacs: | |
387 | |
388 cp /usr/lib/libIM.a . | |
389 chmod 664 libIM.a | |
390 ranlib libIM.a | |
391 | |
392 Then change -lIM to ./libIM.a in the command to link temacs (in | |
393 Makefile). | |

454 | 428 |
429 Alternatively, you can link using the Sun version of ld, which is | |
430 normally held in /usr/ccs/bin. This can be done by one of: | |
431 | |
432 - building gcc with these configure flags: | |
433 configure --with-ld=/usr/ccs/bin/ld --with-as=/usr/ccs/bin/as | |
434 | |
435 - adding -B/usr/ccs/bin/ to CFLAGS used to configure XEmacs | |
436 (Note: The trailing '/' there is significant.) | |
437 | |
438 - uninstalling GNU ld. | |
439 | |
440 The Solaris2 FAQ claims: | |
441 | |
442 When you install gcc, don't make the mistake of installing | |
443 GNU binutils or GNU libc, they are not as capable as their | |
444 counterparts you get with Solaris 2.x. | |
445 | |
373 | 446 *** Link failure when using acc on a Sun. |
447 | |
448 To use acc, you need additional options just before the libraries, such as | |
449 | |
450 /usr/lang/SC2.0.1/values-Xt.o -L/usr/lang/SC2.0.1/cg87 -L/usr/lang/SC2.0.1 | |
451 | |
452 and you need to add -lansi just before -lc. | |
453 | |
454 The precise file names depend on the compiler version, so we | |
455 cannot easily arrange to supply them. | |
456 | |
457 *** Problems finding X11 libraries on Solaris with Openwindows | |
458 | |
459 Some users have reported problems in this area. The reported solution | |
460 is to define the environment variable OPENWINHOME, even if you must set | |
461 it to `/usr/openwin'. | |
462 | |
463 *** Sed problems on Solaris 2.5 | |
464 | |
465 There have been reports of Sun sed truncating very lines in the | |
466 Makefile during configuration. The workaround is to use GNU sed or, | |
454 | 467 even better, think of a better way to generate Makefile, and send us a |
373 | 468 patch. :-) |
469 | |
470 *** On Solaris 2 I get undefined symbols from libcurses.a. | |
471 | |
472 You probably have /usr/ucblib/ on your LD_LIBRARY_PATH. Do the link with | |
473 LD_LIBRARY_PATH unset. Generally, avoid using any ucb* stuff when | |
474 building XEmacs. | |
475 | |
476 *** On Solaris 2 I cannot make alloc.o, glyphs.o or process.o. | |
477 | |
478 The SparcWorks C compiler may have difficulty building those modules | |
479 with optimization level -xO4. Try using only "-fast" optimization | |
480 for just those modules. (Or use gcc). | |
481 | |
482 *** Solaris 2.3 /bin/sh coredumps during configuration. | |
483 | |
484 This only occurs if you have LANG != C. This is a known bug with | |
485 /bin/sh fixed by installing Patch-ID# 101613-01. Or, you can use | |
1697 | 486 bash by setting the environment variable CONFIG_SHELL to /bin/bash |
487 | |
488 *** Solaris 2.x configure fails: ./config.status: test: argument expected | |
489 | |
490 This is a known bug with /bin/sh and /bin/test, i.e. they do not | |
491 support the XPG4 standard. You can use bash as a workaround or an | |
492 XPG4-compliant Bourne shell such as the Sun-supplied /usr/xpg4/bin/sh | |
493 by setting the environment variable CONFIG_SHELL to /usr/xpg4/bin/sh | |
373 | 494 |
495 *** On SunOS, you get linker errors | |
454 | 496 ld: Undefined symbol |
373 | 497 _get_wmShellWidgetClass |
498 _get_applicationShellWidgetClass | |
499 | |
500 The fix to this is to install patch 100573 for OpenWindows 3.0 | |
501 or link libXmu statically. | |
502 | |
503 *** On Sunos 4, you get the error ld: Undefined symbol __lib_version. | |
504 | |
505 This is the result of using cc or gcc with the shared library meant | |
506 for acc (the Sunpro compiler). Check your LD_LIBRARY_PATH and delete | |
507 /usr/lang/SC2.0.1 or some similar directory. | |
508 | |
509 *** Undefined symbols when linking on Sunos 4.1. | |
510 | |
511 If you get the undefined symbols _atowc _wcslen, _iswprint, _iswspace, | |
512 _iswcntrl, _wcscpy, and _wcsncpy, then you need to add -lXwchar after | |
513 -lXaw in the command that links temacs. | |
514 | |
515 This problem seems to arise only when the international language | |
516 extensions to X11R5 are installed. | |
517 | |
518 *** On a Sun running SunOS 4.1.1, you get this error message from GNU ld: | |
519 | |
454 | 520 /lib/libc.a(_Q_sub.o): Undefined symbol __Q_get_rp_rd referenced from text segment |
373 | 521 |
522 The problem is in the Sun shared C library, not in GNU ld. | |
523 | |
524 The solution is to install Patch-ID# 100267-03 from Sun. | |
525 | |
526 *** SunOS 4.1.2: undefined symbol _get_wmShellWidgetClass | |
527 | |
528 Apparently the version of libXmu.so.a that Sun ships is hosed: it's missing | |
454 | 529 some stuff that is in libXmu.a (the static version). Sun has a patch for |
373 | 530 this, but a workaround is to use the static version of libXmu, by changing |
531 the link command from "-lXmu" to "-Bstatic -lXmu -Bdynamic". If you have | |
532 OpenWindows 3.0, ask Sun for these patches: | |
533 100512-02 4.1.x OpenWindows 3.0 libXt Jumbo patch | |
534 100573-03 4.1.x OpenWindows 3.0 undefined symbols with shared libXmu | |
535 | |
536 *** Random other SunOS 4.1.[12] link errors. | |
537 | |
538 The X headers and libraries that Sun ships in /usr/{include,lib}/X11 are | |
539 broken. Use the ones in /usr/openwin/{include,lib} instead. | |
540 | |
541 ** Linux | |
1318 | 542 |
543 See also Intel Architecture General, above. | |
544 | |
545 *** egcs-1.1 on Alpha Linux | |
546 | |
547 There have been reports of egcs-1.1 not compiling XEmacs correctly on | |
548 Alpha Linux. There have also been reports that egcs-1.0.3a is O.K. | |
549 | |
373 | 550 *** Under Linux, you get "too many arguments to function `getpgrp'". |
551 | |
552 You have probably installed LessTiff under `/usr/local' and `libXm.so' | |
553 could not be found when linking `getpgrp()' test program, making XEmacs | |
554 think that `getpgrp()' takes an argument. Try adding `/usr/local/lib' | |
555 in `/etc/ld.so.conf' and run `ldconfig'. Then run XEmacs's `configure' | |
556 again. As with all problems of this type, reading the config.log file | |
557 generated from configure and seeing the log of how the test failed can | |
558 prove enlightening. | |
559 | |
560 *** `Error: No ExtNode to pop!' on Linux systems with Lesstif. | |
197 | 561 |
562 This error message has been observed with lesstif-0.75a. It does not | |
563 appear to cause any harm. | |
564 | |
373 | 565 *** xemacs: can't resolve symbol '__malloc_hook' |
566 | |
567 This is a Linux problem where you've compiled the XEmacs binary on a libc | |
568 5.4 with version higher than 5.4.19 and attempted to run the binary against | |

581 mips2/mips3/mips4 flags, and are they appropriate for the machine in | |

124 | 621 |
622 Darrell Kindred <dkindred@cmu.edu> writes: | |
623 There are a couple of problems [with use of -rpath with Irix ld], though: | |
624 | |
625 1. The ld in IRIX 5.3 ignores all but the last -rpath | |
626 spec, so the patched configure spits out a warning | |
2648 | 627 if --x-libraries or --with-site-runtime-libraries are |
454 | 628 specified under irix 5.x, and it only adds -rpath |
2648 | 629 entries for the --with-site-runtime-libraries. This bug was |
124 | 630 fixed sometime between 5.3 and 6.2. |
631 | |
632 2. IRIX gcc 2.7.2 doesn't accept -rpath directly, so | |
633 it would have to be prefixed by -Xlinker or "-Wl,". | |
634 This would be fine, except that configure compiles with | |
635 ${CC-cc} $CFLAGS $LDFLAGS ... | |
636 rather than quoting $LDFLAGS with prefix-args, like | |
637 src/Makefile does. So if you specify --x-libraries | |
2648 | 638 or --with-site-runtime-libraries, you must use |
639 --with--gcc=no, or configure will fail. | |

679 In particular, src/extents.c and src/faces.c might cause the DEC C | |
680 compiler to abort. When this happens: cd src, compile the files by | |
681 hand, cd .., and redo the "make" command. When recompiling the files by | |
682 hand, use the old C compiler for the following versions of Digital UNIX: | |
683 - V3.n: Remove "-migrate" from the compile command. | |
684 - V4.n: Add "-oldc" to the compile command. | |
685 | |
197 | 686 A related compiler bug has been fixed by the DEC compiler team. The |
687 new versions of the compiler should run fine. | |
126 | 688 |
373 | 689 *** Under some versions of OSF XEmacs runs fine if built without |
690 optimization but will crash randomly if built with optimization. | |
691 | |
692 Using 'cc -g' is not sufficient to eliminate all optimization. Try | |
693 'cc -g -O0' instead. | |
694 | |
695 *** Compilation errors on VMS. | |
696 | |
697 Sorry, XEmacs does not work under VMS. You might consider working on | |
698 the port if you really want to have XEmacs work under VMS. | |

706 Had to drop once again to level 2 optimization, at least to | |

442 | 722 Marcus Thiessel <marcus@xemacs.org> |
278 | 723 |
304 | 724 Some releases of XEmacs (e.g. 20.4) require GNU make to build |
725 successfully. You don't need GNU make when building 21.x. | |
278 | 726 |
373 | 727 *** On HP-UX 9.05 XEmacs won't compile or coredump during the build. |
278 | 728 |

731 This might be a sed problem. For your own safety make sure to use | |
732 GNU sed while dumping XEmacs. | |

373 | 735 ** SCO OpenServer |
736 *** Native cc on SCO OpenServer 5 is now OK. Icc may still throw you | |
197 | 737 a curve. Here is what Robert Lipe <robertl@arnet.com> says: |
124 | 738 |
454 | 739 Unlike XEmacs 19.13, building with the native cc on SCO OpenServer 5 |
124 | 740 now produces a functional binary. I will typically build this |
741 configuration for COFF with: | |
742 | |
197 | 743 /path_to_xemacs_source/configure --with-gcc=no \ |
2648 | 744 --with-site-includes=/usr/local/include \ |

454 | 748 This version now supports ELF builds. I highly recommend this to |
749 reduce the in-core footprint of XEmacs. This is now how I compile | |
124 | 750 all my test releases. Build it like this: |
751 | |
752 /path_to_XEmacs_source/configure --with-gcc=no \ | |

454 | 757 The compiler known as icc [ supplied with the OpenServer 5 Development |
124 | 758 System ] generates a working binary, but it takes forever to generate |
759 XEmacs. ICC also whines more about the code than /bin/cc does. I do | |
760 believe all its whining is legitimate, however. Note that you do | |
761 have to 'cd src ; make LD=icc' to avoid linker errors. | |
762 | |
763 The way I handle the build procedure is: | |
764 | |
765 /path_to_XEmacs_source/configure --with-gcc=no \ | |

773 don't include the "--with-*" arguments in any of my examples. | |
774 | |
454 | 775 In previous versions of XEmacs, you had to override the defaults while |
124 | 776 compiling font-lock.o and extents.o when building with icc. This seems |
777 to no longer be true, but I'm including this old information in case it | |
778 resurfaces. The process I used was: | |
779 | |
454 | 780 make -k |
781 [ procure pizza, beer, repeat ] | |
124 | 782 cd src |
783 make CC="icc -W0,-mP1COPT_max_tree_size=3000" font-lock.o extents.o | |
784 make LD=icc | |
785 | |
454 | 786 If you want sound support, get the tls566 supplement from |
787 ftp.sco.com:/TLS or any of its mirrors. It works just groovy | |
124 | 788 with XEmacs. |

790 The M-x manual-entry is known not to work. If you know Lisp and would | |
791 like help in making it work, e-mail me at <robertl@dgii.com>. | |
792 (UNCHECKED for 19.15 -- it might work). | |
793 | |
454 | 794 In earlier releases, gnuserv/gnuclient/gnudoit would open a frame |
124 | 795 just fine, but the client would lock up and the server would |
454 | 796 terminate when you used C-x # to close the frame. This is now |
124 | 797 fixed in XEmacs. |
798 | |
799 In etc/ there are two files of note. emacskeys.sco and emacsstrs.sco. | |
800 The comments at the top of emacskeys.sco describe its function, and | |
801 the emacstrs.sco is a suitable candidate for /usr/lib/keyboard/strings | |
802 to take advantage of the keyboard map in emacskeys.sco. | |
803 | |
373 | 804 Note: Much of the above entry is probably not valid for XEmacs 21.0 |
207 | 805 and later. |

810 | |
811 or "ispell" or other commands that seem related to whatever you just | |
812 tried to do. | |
813 | |
814 There are a large number of common (in the sense that "everyone has | |
815 these, really") Unix utilities that are not provided with XEmacs. The | |
816 GNU Project's implementations are available for Windows in the the | |
817 Cygwin distribution (http://www.cygwin.com/), which also provides a | |
818 complete Unix emulation environment (and thus makes ports of Unix | |
819 utilities nearly trivial). Another implementation is that from MinGW | |
820 (http://www.mingw.org/msys.shtml). | |
821 | |
1332 | 822 *** Weird crashes in pdump load or shortly after pdump load. |
823 | |
824 This can happen with incremental linking. Check if you have set | |
825 SUPPORT_EDIT_AND_CONTINUE to non-zero in config.inc, which must allow | |
826 incremental linking to be enabled (otherwise it's disabled). Either turn | |
827 this off, execute `nmake -f xemacs.mak clean', or manually remove | |
828 `temacs.exe' and `xemacs.exe'. | |

869 the Cygwin utilities specify explicitly whether they want binary or | |
870 text mode when working with source vs. binary files, which overrides | |
871 the mount type.) To fix this, you just need to run the appropriate | |
872 mount command once -- afterwards, the settings are remembered in the | |
873 registry. | |
392 | 874 |

373 | 898 * Problems with running XEmacs |
899 ============================== | |
900 ** General | |
1332 | 901 |
902 *** Changes made to .el files do not take effect. | |
903 | |
904 You may have forgotten to recompile them into .elc files. Then the | |
905 old .elc files will be loaded, and your changes will not be seen. To | |
906 fix this, do `M-x byte-recompile-directory' and specify the directory | |
907 that contains the Lisp files. | |
908 | |
909 Note that you will get a warning when loading a .elc file that is | |
910 older than the corresponding .el file. | |
911 | |
912 *** VM appears to hang in large folders. | |
913 | |
914 This is normal (trust us) when upgrading to VM-6.22 from earlier | |
915 versions. Let VM finish what it is doing and all will be well. | |
1042 | 916 |
892 | 917 *** Starting with 21.4.x, killing text is absurdly slow. |
918 | |
919 See FAQ Q3.10.6. Should be available on the web near | |
920 http://www.xemacs.org/faq/xemacs-faq.html#SEC160. | |
921 | |
835 | 922 *** Whenever I try to retrieve a remote file, I have problems. |
923 | |
924 A typical error: FTP Error: USER request failed; 500 AUTH not understood. | |
925 Thanks to giacomo boffi <giacomo.boffi@polimi.it> on comp.emacs.xemacs: | |
926 | |
927 tell your ftp client to not attempt AUTH authentication (or do not | |
928 use FTP servers that don't understand AUTH) | |
929 | |
930 and notes that you need to add an element (often "-u") to | |
931 `efs-ftp-program-args'. Use M-x customize-variable, and verify the | |
932 needed flag with `man ftp' or other local documentation. | |
933 | |
464 | 934 *** gnuserv is running, some clients can connect, but others cannot. |
935 | |
936 The code in gnuslib.c respects the value of TMPDIR. If the server and | |
937 the client have different values in their environment, you lose. | |
938 One program known to set TMPDIR and manifest this problem is exmh. | |
939 You can defeat the use of TMPDIR by unsetting USE_TMPDIR at the top of | |
940 gnuserv.h at build time. | |
941 | |
1332 | 942 ** General Unix |
124 | 943 |
373 | 944 *** You type Control-H (Backspace) expecting to delete characters. |
124 | 945 |
946 Emacs has traditionally used Control-H for help; unfortunately this | |
424 | 947 interferes with its use as Backspace on TTY's. As of XEmacs 21, |
948 XEmacs looks at the "erase" setting of TTY structures and maps C-h to | |
949 backspace when erase is set to C-h. This is sort of a special hack, | |
950 but it makes it possible for you to use the standard: | |
951 | |
952 stty erase ^H | |
355 | 953 |
424 | 954 to get your backspace key to erase characters. The erase setting is |
955 recorded in the Lisp variable `tty-erase-char', which you can use to | |
956 tune the settings in your .emacs. | |
124 | 957 |
424 | 958 A major drawback of this is that when C-h becomes backspace, it no |
959 longer invokes help. In that case, you need to use f1 for help, or | |
960 bind another key. An example of the latter is the following code, | |
961 which moves help to Meta-? (ESC ?): | |
124 | 962 |
424 | 963 (global-set-key "\M-?" 'help-command) |
124 | 964 |
1332 | 965 *** At startup I get a warning on stderr about missing charsets: |
966 | |
967 Warning: Missing charsets in String to FontSet conversion | |
968 | |
969 You need to specify appropriate charsets for your locale (usually the | |
970 value of the LANG environment variable) in .Xresources. See | |
971 etc/Emacs.ad for the relevant resources (mostly menubar fonts and | |
972 fontsets). Do not edit this file, it's purely informative. | |
973 | |
974 If you have no satisfactory fonts for iso-8859-1, XEmacs will crash. | |
975 | |
976 It looks like XFree86 4.x (the usual server on Linux and *BSD) has | |
977 some braindamage where .UTF-8 locales will always generate this | |
978 message, because the XFree86 (font)server doesn't know that UTF-8 will | |
979 use the ISO10646-1 font registry (or a Cmap or something). | |
980 | |
981 If you are not using a .UTF-8 locale and see this warning for a | |
982 character set not listed in the default in Emacs.ad, please let | |
983 xemacs-beta@xemacs.org know about it, so we can add fonts to the | |
984 appropriate fontsets and stifle this warning. (Unfortunately it's | |
985 buried in Xlib, so we can't easily get rid of it otherwise.) | |
986 | |
373 | 987 *** Mail agents (VM, Gnus, rmail) cannot get new mail |
197 | 988 |
989 rmail and VM get new mail from /usr/spool/mail/$USER using a program | |
990 called `movemail'. This program interlocks with /bin/mail using the | |
991 protocol defined by /bin/mail. | |
992 | |
993 There are two different protocols in general use. One of them uses | |
994 the `flock' system call. The other involves creating a lock file; | |
995 `movemail' must be able to write in /usr/spool/mail in order to do | |
996 this. You control which one is used by defining, or not defining, the | |
997 macro MAIL_USE_FLOCK in config.h or the m- or s- file it includes. IF | |
998 YOU DON'T USE THE FORM OF INTERLOCKING THAT IS NORMAL ON YOUR SYSTEM, | |
999 YOU CAN LOSE MAIL! | |
1000 | |
1001 If your system uses the lock file protocol, and fascist restrictions | |
1002 prevent ordinary users from writing the lock files in /usr/spool/mail, | |
1003 you may need to make `movemail' setgid to a suitable group such as | |
1004 `mail'. To do this, use the following commands (as root) after doing | |
1005 the make install. | |
1006 | |
1007 chgrp mail movemail | |
1008 chmod 2755 movemail | |
1009 | |
1010 Installation normally copies movemail from the build directory to an | |
1011 installation directory which is usually under /usr/local/lib. The | |
1012 installed copy of movemail is usually in the directory | |
1013 /usr/local/lib/emacs/VERSION/TARGET. You must change the group and | |
1014 mode of the installed copy; changing the group and mode of the build | |
1015 directory copy is ineffective. | |
1016 | |
373 | 1017 *** Things which should be bold or italic (such as the initial |
197 | 1018 copyright notice) are not. |
0 | 1019 |
197 | 1020 The fonts of the "bold" and "italic" faces are generated from the font |
1021 of the "default" face; in this way, your bold and italic fonts will | |
1022 have the appropriate size and family. However, emacs can only be | |
1023 clever in this way if you have specified the default font using the | |
1024 XLFD (X Logical Font Description) format, which looks like | |
0 | 1025 |
1026 *-courier-medium-r-*-*-*-120-*-*-*-*-*-* | |
1027 | |
197 | 1028 if you use any of the other, less strict font name formats, some of |
1029 which look like: | |
1030 | |
0 | 1031 lucidasanstypewriter-12 |
1032 and fixed | |
1033 and 9x13 | |
1034 | |
1035 then emacs won't be able to guess the names of the "bold" and "italic" | |
1036 versions. All X fonts can be referred to via XLFD-style names, so you | |
1037 should use those forms. See the man pages for X(1), xlsfonts(1), and | |
1038 xfontsel(1). | |
1039 | |
373 | 1040 *** The dumped Emacs crashes when run, trying to write pure data. |
0 | 1041 |
1042 Two causes have been seen for such problems. | |
1043 | |
1044 1) On a system where getpagesize is not a system call, it is defined | |
1045 as a macro. If the definition (in both unexec.c and malloc.c) is wrong, | |
1046 it can cause problems like this. You might be able to find the correct | |
1047 value in the man page for a.out (5). | |
1048 | |
1049 2) Some systems allocate variables declared static among the | |
1050 initialized variables. Emacs makes all initialized variables in most | |
1051 of its files pure after dumping, but the variables declared static and | |
1052 not initialized are not supposed to be pure. On these systems you | |
1053 may need to add "#define static" to the m- or the s- file. | |
1054 | |
373 | 1055 *** Reading and writing files is very very slow. |
0 | 1056 |
1057 Try evaluating the form (setq lock-directory nil) and see if that helps. | |

373 | 1062 *** When emacs starts up, I get lots of warnings about unknown keysyms. |
124 | 1063 |
1064 If you are running the prebuilt binaries, the Motif library expects to find | |
1065 certain thing in the XKeysymDB file. This file is normally in /usr/lib/X11/ | |
1066 or in /usr/openwin/lib/. If you keep yours in a different place, set the | |
454 | 1067 environment variable $XKEYSYMDB to point to it before starting emacs. If |
1068 you still have the problem after doing that, perhaps your version of X is | |
2536 | 1069 too old. There is a copy of the MIT X11R6 XKeysymDB file in the emacs `etc' |
124 | 1070 directory. Try using that one. |
1071 | |
3406 | 1072 *** Lots of warnings generated when displaying via ssh X forwarding. |
1073 | |
1074 If you are seeing a significant number of X11 warnings (in particular | |
1075 BadWindow errors) when using XEmacs via ssh X forwarding try using a | |
1076 trusted x11 connection instead (for openssh, use -Y instead of -X). | |

124 | 1080 Check the resources in .../etc/Emacs.ad (which is the same as the file |
1389 | 1081 sample.Xresources). Perhaps some of the default resources built in to |
124 | 1082 emacs are now overriding your existing resources. Copy and edit the |
1083 resources in Emacs.ad as necessary. | |
1084 | |
373 | 1085 *** I have focus problems when I use `M-o' to switch to another screen |
197 | 1086 without using the mouse. |
124 | 1087 |
197 | 1088 The focus issues with a program like XEmacs, which has multiple |
1089 homogeneous top-level windows, are very complicated, and as a result, | |
1090 most window managers don't implement them correctly. | |
0 | 1091 |
124 | 1092 The R4/R5 version of twm (and all of its descendants) had buggy focus |
197 | 1093 handling. Sufficiently recent versions of tvtwm have been fixed. In |
1094 addition, if you're using twm, make sure you have not specified | |
1095 "NoTitleFocus" in your .tvtwmrc file. The very nature of this option | |
1096 makes twm do some illegal focus tricks, even with the patch. | |
0 | 1097 |
197 | 1098 It is known that olwm and olvwm are buggy, and in different ways. If |
1099 you're using click-to-type mode, try using point-to-type, or vice | |
1100 versa. | |
0 | 1101 |
197 | 1102 In older versions of NCDwm, one could not even type at XEmacs windows. |
1103 This has been fixed in newer versions (2.4.3, and possibly earlier). | |
0 | 1104 |
197 | 1105 (Many people suggest that XEmacs should warp the mouse when focusing |
1106 on another screen in point-to-type mode. This is not ICCCM-compliant | |
1107 behavior. Implementing such policy is the responsibility of the | |
1108 window manager itself, it is not legal for a client to do this.) | |
0 | 1109 |
373 | 1110 *** Emacs spontaneously displays "I-search: " at the bottom of the screen. |
0 | 1111 |
1112 This means that Control-S/Control-Q (XON/XOFF) "flow control" is being | |
1113 used. C-s/C-q flow control is bad for Emacs editors because it takes | |
1114 away C-s and C-q as user commands. Since editors do not output long | |
1115 streams of text without user commands, there is no need for a | |
1116 user-issuable "stop output" command in an editor; therefore, a | |
1117 properly designed flow control mechanism would transmit all possible | |
1118 input characters without interference. Designing such a mechanism is | |
1119 easy, for a person with at least half a brain. | |
1120 | |
1121 There are three possible reasons why flow control could be taking place: | |
1122 | |
1123 1) Terminal has not been told to disable flow control | |
1124 2) Insufficient padding for the terminal in use | |
1125 3) Some sort of terminal concentrator or line switch is responsible | |
1126 | |
1127 First of all, many terminals have a set-up mode which controls whether | |
1128 they generate XON/XOFF flow control characters. This must be set to | |
1129 "no XON/XOFF" in order for Emacs to work. Sometimes there is an | |
1130 escape sequence that the computer can send to turn flow control off | |
1131 and on. If so, perhaps the termcap `ti' string should turn flow | |
1132 control off, and the `te' string should turn it on. | |
1133 | |
1134 Once the terminal has been told "no flow control", you may find it | |
1135 needs more padding. The amount of padding Emacs sends is controlled | |
1136 by the termcap entry for the terminal in use, and by the output baud | |
1137 rate as known by the kernel. The shell command `stty' will print | |
1138 your output baud rate; `stty' with suitable arguments will set it if | |
1139 it is wrong. Setting to a higher speed causes increased padding. If | |
1140 the results are wrong for the correct speed, there is probably a | |
1141 problem in the termcap entry. You must speak to a local Unix wizard | |
1142 to fix this. Perhaps you are just using the wrong terminal type. | |
1143 | |
1144 For terminals that lack a "no flow control" mode, sometimes just | |
1145 giving lots of padding will prevent actual generation of flow control | |
1146 codes. You might as well try it. | |
1147 | |
1148 If you are really unlucky, your terminal is connected to the computer | |
1149 through a concentrator which sends XON/XOFF flow control to the | |
1150 computer, or it insists on sending flow control itself no matter how | |
1151 much padding you give it. Unless you can figure out how to turn flow | |
1152 control off on this concentrator (again, refer to your local wizard), | |
1153 you are screwed! You should have the terminal or concentrator | |
1154 replaced with a properly designed one. In the mean time, some drastic | |
1155 measures can make Emacs semi-work. | |
1156 | |
1157 You can make Emacs ignore C-s and C-q and let the operating system | |
1158 handle them. To do this on a per-session basis, just type M-x | |
1159 enable-flow-control RET. You will see a message that C-\ and C-^ are | |
1160 now translated to C-s and C-q. (Use the same command M-x | |
1161 enable-flow-control to turn *off* this special mode. It toggles flow | |
1162 control handling.) | |
1163 | |
1164 If C-\ and C-^ are inconvenient for you (for example, if one of them | |
1165 is the escape character of your terminal concentrator), you can choose | |
1166 other characters by setting the variables flow-control-c-s-replacement | |
1167 and flow-control-c-q-replacement. But choose carefully, since all | |
1168 other control characters are already used by emacs. | |
1169 | |
1170 IMPORTANT: if you type C-s by accident while flow control is enabled, | |
1171 Emacs output will freeze, and you will have to remember to type C-q in | |
1172 order to continue. | |
1173 | |
1174 If you work in an environment where a majority of terminals of a | |
1175 certain type are flow control hobbled, you can use the function | |
1176 `enable-flow-control-on' to turn on this flow control avoidance scheme | |
1177 automatically. Here is an example: | |
1178 | |
1179 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131") | |
1180 | |
1181 If this isn't quite correct (e.g. you have a mixture of flow-control hobbled | |
1182 and good vt200 terminals), you can still run enable-flow-control | |
1183 manually. | |
1184 | |
1185 I have no intention of ever redesigning the Emacs command set for the | |
1186 assumption that terminals use C-s/C-q flow control. XON/XOFF flow | |
1187 control technique is a bad design, and terminals that need it are bad | |
1188 merchandise and should not be purchased. Now that X is becoming | |
1189 widespread, XON/XOFF seems to be on the way out. If you can get some | |
1190 use out of GNU Emacs on inferior terminals, more power to you, but I | |
1191 will not make Emacs worse for properly designed systems for the sake | |
1192 of inferior systems. | |
1193 | |
373 | 1194 *** Control-S and Control-Q commands are ignored completely. |
0 | 1195 |
1196 For some reason, your system is using brain-damaged C-s/C-q flow | |
1197 control despite Emacs's attempts to turn it off. Perhaps your | |
1198 terminal is connected to the computer through a concentrator | |
1199 that wants to use flow control. | |
1200 | |
1201 You should first try to tell the concentrator not to use flow control. | |
1202 If you succeed in this, try making the terminal work without | |
1203 flow control, as described in the preceding section. | |
1204 | |
1205 If that line of approach is not successful, map some other characters | |
1206 into C-s and C-q using keyboard-translate-table. The example above | |
1207 shows how to do this with C-^ and C-\. | |
1208 | |
373 | 1209 *** Control-S and Control-Q commands are ignored completely on a net |
197 | 1210 connection. |
0 | 1211 |
1212 Some versions of rlogin (and possibly telnet) do not pass flow | |
1213 control characters to the remote system to which they connect. | |
1214 On such systems, emacs on the remote system cannot disable flow | |
1215 control on the local system. | |
1216 | |
1217 One way to cure this is to disable flow control on the local host | |
1218 (the one running rlogin, not the one running rlogind) using the | |
1219 stty command, before starting the rlogin process. On many systems, | |
120 | 1220 `stty start u stop u' will do this. |
0 | 1221 |
1222 Some versions of tcsh will prevent even this from working. One way | |
1223 around this is to start another shell before starting rlogin, and | |
1224 issue the stty command to disable flow control from that shell. | |
1225 | |
1226 If none of these methods work, the best solution is to type | |
120 | 1227 `M-x enable-flow-control' at the beginning of your emacs session, or |
0 | 1228 if you expect the problem to continue, add a line such as the |
1229 following to your .emacs (on the host running rlogind): | |
1230 | |
1231 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131") | |
1232 | |
1233 See the entry about spontaneous display of I-search (above) for more | |
1234 info. | |
1235 | |
373 | 1236 *** TTY redisplay is slow. |
197 | 1237 |
1238 XEmacs has fairly new TTY redisplay support (beginning from 19.12), | |
1239 which doesn't include some basic TTY optimizations -- like using | |
1240 scrolling regions to move around blocks of text. This is why | |
454 | 1241 redisplay on the traditional terminals, or over slow lines can be very |
197 | 1242 slow. |
1243 | |
1244 If you are interested in fixing this, please let us know at | |
1332 | 1245 <xemacs-beta@xemacs.org>. |
197 | 1246 |
373 | 1247 *** Screen is updated wrong, but only on one kind of terminal. |
0 | 1248 |
120 | 1249 This could mean that the termcap entry you are using for that terminal |
1250 is wrong, or it could mean that Emacs has a bug handing the | |
1251 combination of features specified for that terminal. | |
0 | 1252 |
1253 The first step in tracking this down is to record what characters | |
1254 Emacs is sending to the terminal. Execute the Lisp expression | |
120 | 1255 (open-termscript "./emacs-script") to make Emacs write all terminal |
1256 output into the file ~/emacs-script as well; then do what makes the | |
1257 screen update wrong, and look at the file and decode the characters | |
1258 using the manual for the terminal. There are several possibilities: | |
0 | 1259 |
1260 1) The characters sent are correct, according to the terminal manual. | |
1261 | |
1262 In this case, there is no obvious bug in Emacs, and most likely you | |
1263 need more padding, or possibly the terminal manual is wrong. | |
1264 | |
120 | 1265 2) The characters sent are incorrect, due to an obscure aspect of the |
1266 terminal behavior not described in an obvious way by termcap. | |
0 | 1267 |
120 | 1268 This case is hard. It will be necessary to think of a way for Emacs |
1269 to distinguish between terminals with this kind of behavior and other | |
1270 terminals that behave subtly differently but are classified the same | |
1271 by termcap; or else find an algorithm for Emacs to use that avoids the | |
1272 difference. Such changes must be tested on many kinds of terminals. | |
0 | 1273 |
1274 3) The termcap entry is wrong. | |
1275 | |
120 | 1276 See the file etc/TERMS for information on changes that are known to be |
1277 needed in commonly used termcap entries for certain terminals. | |
0 | 1278 |
120 | 1279 4) The characters sent are incorrect, and clearly cannot be right for |
1280 any terminal with the termcap entry you were using. | |
0 | 1281 |
120 | 1282 This is unambiguously an Emacs bug, and can probably be fixed in |
197 | 1283 termcap.c, terminfo.c, tparam.c, cm.c, redisplay-tty.c, |
1284 redisplay-output.c, or redisplay.c. | |
0 | 1285 |
373 | 1286 *** My buffers are full of \000 characters or otherwise corrupt. |
1287 | |
1288 Some compilers have trouble with gmalloc.c and ralloc.c; try recompiling | |
1289 without optimization. If that doesn't work, try recompiling with | |
1290 SYSTEM_MALLOC defined, and/or with REL_ALLOC undefined. | |
1291 | |
1389 | 1292 *** A position you specified in .Xresources is ignored, using twm. |
373 | 1293 |
1294 twm normally ignores "program-specified" positions. | |
1295 You can tell it to obey them with this command in your `.twmrc' file: | |
1296 | |
1297 UsePPosition "on" #allow clents to request a position | |
1298 | |
1299 *** With M-x enable-flow-control, you need to type C-\ twice to do | |
1300 incremental search--a single C-\ gets no response. | |
1301 | |
1302 This has been traced to communicating with your machine via kermit, | |
1303 with C-\ as the kermit escape character. One solution is to use | |
1304 another escape character in kermit. One user did | |
1305 | |
1306 set escape-character 17 | |
1307 | |
1308 in his .kermrc file, to make C-q the kermit escape character. | |
1309 | |
1310 *** The Motif version of Emacs paints the screen a solid color. | |
1311 | |
1312 This has been observed to result from the following X resource: | |
1313 | |
1314 Emacs*default.attributeFont: -*-courier-medium-r-*-*-*-140-*-*-*-*-iso8859-* | |
1315 | |
1316 That the resource has this effect indicates a bug in something, but we | |
1317 do not yet know what. If it is an Emacs bug, we hope someone can | |
1318 explain what the bug is so we can fix it. In the mean time, removing | |
1319 the resource prevents the problem. | |
1320 | |
1321 *** After running emacs once, subsequent invocations crash. | |
1322 | |
1323 Some versions of SVR4 have a serious bug in the implementation of the | |
1324 mmap () system call in the kernel; this causes emacs to run correctly | |
1325 the first time, and then crash when run a second time. | |
1326 | |
1327 Contact your vendor and ask for the mmap bug fix; in the mean time, | |
1328 you may be able to work around the problem by adding a line to your | |
1329 operating system description file (whose name is reported by the | |
1330 configure script) that reads: | |
1331 #define SYSTEM_MALLOC | |
1332 This makes Emacs use memory less efficiently, but seems to work around | |
1333 the kernel bug. | |
1334 | |
1335 *** Inability to send an Alt-modified key, when Emacs is communicating | |
1336 directly with an X server. | |
1337 | |
1338 If you have tried to bind an Alt-modified key as a command, and it | |
1339 does not work to type the command, the first thing you should check is | |
1340 whether the key is getting through to Emacs. To do this, type C-h c | |
1341 followed by the Alt-modified key. C-h c should say what kind of event | |
1342 it read. If it says it read an Alt-modified key, then make sure you | |
1343 have made the key binding correctly. | |
1344 | |
1345 If C-h c reports an event that doesn't have the Alt modifier, it may | |
1346 be because your X server has no key for the Alt modifier. The X | |
1347 server that comes from MIT does not set up the Alt modifier by | |
1348 default. | |
1349 | |
1350 If your keyboard has keys named Alt, you can enable them as follows: | |
1351 | |
1352 xmodmap -e 'add mod2 = Alt_L' | |
1353 xmodmap -e 'add mod2 = Alt_R' | |
1354 | |
1355 If the keyboard has just one key named Alt, then only one of those | |
1356 commands is needed. The modifier `mod2' is a reasonable choice if you | |
1357 are using an unmodified MIT version of X. Otherwise, choose any | |
1358 modifier bit not otherwise used. | |
1359 | |
1360 If your keyboard does not have keys named Alt, you can use some other | |
1361 keys. Use the keysym command in xmodmap to turn a function key (or | |
1362 some other 'spare' key) into Alt_L or into Alt_R, and then use the | |
1363 commands show above to make them modifier keys. | |
1364 | |
1365 Note that if you have Alt keys but no Meta keys, Emacs translates Alt | |
1366 into Meta. This is because of the great importance of Meta in Emacs. | |
1367 | |
1368 *** In Shell mode, you get a ^M at the end of every line. | |
1369 | |
1370 This happens to people who use tcsh, because it is trying to be too | |
1371 smart. It sees that the Shell uses terminal type `unknown' and turns | |
1372 on the flag to output ^M at the end of each line. You can fix the | |
1373 problem by adding this to your .cshrc file: | |
1374 | |
1375 if ($?EMACS) then | |
1376 if ($EMACS == "t") then | |
454 | 1377 unset edit |
373 | 1378 stty -icrnl -onlcr -echo susp ^Z |
1379 endif | |
1380 endif | |
1381 | |
1382 *** An error message such as `X protocol error: BadMatch (invalid | |
1383 parameter attributes) on protocol request 93'. | |
1384 | |
1385 This comes from having an invalid X resource, such as | |
1386 emacs*Cursor: black | |
1387 (which is invalid because it specifies a color name for something | |
1388 that isn't a color.) | |
1389 | |
1390 The fix is to correct your X resources. | |
1391 | |
1392 *** Once you pull down a menu from the menubar, it won't go away. | |
1393 | |
1394 It has been claimed that this is caused by a bug in certain very old | |
1395 (1990?) versions of the twm window manager. It doesn't happen with | |
1396 recent vintages, or with other window managers. | |
1397 | |
1398 *** Emacs ignores the "help" key when running OLWM. | |
1399 | |
1400 OLWM grabs the help key, and retransmits it to the appropriate client | |
1401 using XSendEvent. Allowing emacs to react to synthetic events is a | |
1402 security hole, so this is turned off by default. You can enable it by | |
1403 setting the variable x-allow-sendevents to t. You can also cause fix | |
1404 this by telling OLWM to not grab the help key, with the null binding | |
1405 "OpenWindows.KeyboardCommand.Help:". | |
1406 | |
1407 *** Programs running under terminal emulator do not recognize `emacs' | |
1408 terminal type. | |
1409 | |
1410 The cause of this is a shell startup file that sets the TERMCAP | |
1411 environment variable. The terminal emulator uses that variable to | |
1412 provide the information on the special terminal type that Emacs | |
1413 emulates. | |
1414 | |
1415 Rewrite your shell startup file so that it does not change TERMCAP | |
1416 in such a case. You could use the following conditional which sets | |
1417 it only if it is undefined. | |
1418 | |
1419 if ( ! ${?TERMCAP} ) setenv TERMCAP ~/my-termcap-file | |
1420 | |
1421 Or you could set TERMCAP only when you set TERM--which should not | |
1422 happen in a non-login shell. | |
1423 | |
442 | 1424 *** The popup menu appears at the bottom/right of my screen. |

1441 | |
1442 This problem stems from a gcc bug. With no optimization, functions | |

1036 | 1466 *** XEmacs crashes on MacOS within font-lock, or when dealing |
1467 with large compilation buffers, or in other regex applications. | |
1468 | |
3074 | 1469 The default stack size under MacOS/X prior to 10.3 (Panther) is rather |
1470 small (512k as opposed to Solaris 8M), hosing the regexp code, which | |
1471 uses alloca() extensively, overflowing the stack when complex regexps | |
1472 are used. Workarounds: | |
1036 | 1473 |
1474 1) Increase your stack size, using `ulimit -s 8192' or a (t)csh | |
1475 equivalent; | |
1476 | |
1477 2) Recompile regex.c with REGEX_MALLOC defined. | |
1478 | |
373 | 1479 ** AIX |
1480 *** Your Delete key sends a Backspace to the terminal, using an AIXterm. | |
0 | 1481 |
1389 | 1482 The solution is to include in your .Xresources the lines: |
0 | 1483 |
1484 *aixterm.Translations: #override <Key>BackSpace: string(0x7f) | |
1485 aixterm*ttyModes: erase ^? | |
1486 | |
1487 This makes your Backspace key send DEL (ASCII 127). | |
1488 | |
373 | 1489 *** On AIX 4, some programs fail when run in a Shell buffer |
1490 with an error message like No terminfo entry for "unknown". | |
124 | 1491 |
373 | 1492 On AIX, many terminal type definitions are not installed by default. |
1493 `unknown' is one of them. Install the "Special Generic Terminal | |
1494 Definitions" to make them defined. | |
124 | 1495 |
373 | 1496 *** On AIX, you get this message when running Emacs: |
0 | 1497 |
373 | 1498 Could not load program emacs |
1499 Symbol smtcheckinit in csh is undefined | |
1500 Error was: Exec format error | |

1506 Symbol _fp_trapsta in csh is undefined | |
1507 Error was: Exec format error | |
124 | 1508 |
373 | 1509 These can happen when you try to run on AIX 3.2.5 a program that was |
1510 compiled with 3.2.4. The fix is to recompile. | |
124 | 1511 |
373 | 1512 *** Trouble using ptys on AIX. |
1513 | |
1514 People often install the pty devices on AIX incorrectly. | |
1515 Use `smit pty' to reinstall them properly. | |

373 | 1518 ** SunOS/Solaris |
1519 *** The Emacs window disappears when you type M-q. | |
197 | 1520 |
373 | 1521 Some versions of the Open Look window manager interpret M-q as a quit |
1522 command for whatever window you are typing at. If you want to use | |
1523 Emacs with that window manager, you should try to configure the window | |
1524 manager to use some other command. You can disable the | |
1525 shortcut keys entirely by adding this line to ~/.OWdefaults: | |
0 | 1526 |
373 | 1527 OpenWindows.WindowMenuAccelerators: False |
1528 | |
1529 *** When Emacs tries to ring the bell, you get an error like | |
124 | 1530 |
1531 audio: sst_open: SETQSIZE" Invalid argument | |
1532 audio: sst_close: SETREG MMR2, Invalid argument | |
1533 | |
197 | 1534 you have probably compiled using an ANSI C compiler, but with non-ANSI |
1535 include files. In particular, on Suns, the file | |
1536 /usr/include/sun/audioio.h uses the _IOW macro to define the constant | |
1537 AUDIOSETQSIZE. _IOW in turn uses a K&R preprocessor feature that is | |
1538 now explicitly forbidden in ANSI preprocessors, namely substitution | |
1539 inside character constants. All ANSI C compilers must provide a | |
1540 workaround for this problem. Lucid's C compiler is shipped with a new | |
1541 set of system include files. If you are using GCC, there is a script | |
1542 called fixincludes that creates new versions of some system include | |
1543 files that use this obsolete feature. | |
124 | 1544 |
373 | 1545 *** On Solaris 2.6, XEmacs dumps core when exiting. |
0 | 1546 |
373 | 1547 This happens if you're XEmacs is running on the same machine as the X |
1548 server, and the optimized memory transport has been turned on by | |
1549 setting the environment variable XSUNTRANSPORT. The crash occurs | |
1550 during the call to XCloseDisplay. | |
124 | 1551 |
373 | 1552 If this describes your situation, you need to undefine the |
1553 XSUNTRANSPORT environment variable. | |
126 | 1554 |
373 | 1555 *** On Solaris, C-x doesn't get through to Emacs when you use the console. |
124 | 1556 |
373 | 1557 This is a Solaris feature (at least on Intel x86 cpus). Type C-r |
1558 C-r C-t, to toggle whether C-x gets through to Emacs. | |
124 | 1559 |
373 | 1560 *** On Solaris 2.4, Dired hangs and C-g does not work. Or Emacs hangs |
197 | 1561 forever waiting for termination of a subprocess that is a zombie. |
124 | 1562 |
1563 casper@fwi.uva.nl says the problem is in X11R6. Rebuild libX11.so | |
1564 after changing the file xc/config/cf/sunLib.tmpl. Change the lines | |
1565 | |
1566 #if ThreadedX | |
1567 #define SharedX11Reqs -lthread | |
1568 #endif | |
1569 | |
1570 to: | |
1571 | |
1572 #if OSMinorVersion < 4 | |
1573 #if ThreadedX | |
1574 #define SharedX11Reqs -lthread | |
1575 #endif | |
1576 #endif | |
1577 | |
1578 Be sure also to edit x/config/cf/sun.cf so that OSMinorVersion is 4 | |
1579 (as it should be for Solaris 2.4). The file has three definitions for | |
1580 OSMinorVersion: the first is for x86, the second for SPARC under | |
1581 Solaris, and the third for SunOS 4. Make sure to update the | |
1582 definition for your type of machine and system. | |
1583 | |
1584 Then do `make Everything' in the top directory of X11R6, to rebuild | |
1585 the makefiles and rebuild X. The X built this way work only on | |
1586 Solaris 2.4, not on 2.3. | |
1587 | |
1588 For multithreaded X to work it necessary to install patch | |
1589 101925-02 to fix problems in header files [2.4]. You need | |
1590 to reinstall gcc or re-run just-fixinc after installing that | |
1591 patch. | |
0 | 1592 |
124 | 1593 However, Frank Rust <frust@iti.cs.tu-bs.de> used a simpler solution: |
1594 he changed | |
1595 #define ThreadedX YES | |
1596 to | |
1597 #define ThreadedX NO | |
1598 in sun.cf and did `make World' to rebuild X11R6. Removing all | |
1599 `-DXTHREAD*' flags and `-lthread' entries from lib/X11/Makefile and | |
1600 typing 'make install' in that directory also seemed to work. | |
1601 | |
373 | 1602 *** On SunOS 4.1.3, Emacs unpredictably crashes in _yp_dobind_soft. |
124 | 1603 |
373 | 1604 This happens if you configure Emacs specifying just `sparc-sun-sunos4' |
1605 on a system that is version 4.1.3. You must specify the precise | |
1606 version number (or let configure figure out the configuration, which | |
1607 it can do perfectly well for SunOS). | |
124 | 1608 |
373 | 1609 *** Mail is lost when sent to local aliases. |
0 | 1610 |
124 | 1611 Many emacs mail user agents (VM and rmail, for instance) use the |
1612 sendmail.el library. This library can arrange for mail to be | |
1613 delivered by passing messages to the /usr/lib/sendmail (usually) | |
1614 program . In doing so, it passes the '-t' flag to sendmail, which | |
1615 means that the name of the recipient of the message is not on the | |
1616 command line and, therefore, that sendmail must parse the message to | |
1617 obtain the destination address. | |
1618 | |
1619 There is a bug in the SunOS4.1.1 and SunOS4.1.3 versions of sendmail. | |
1620 In short, when given the -t flag, the SunOS sendmail won't recognize | |
1621 non-local (i.e. NIS) aliases. It has been reported that the Solaris | |
1622 2.x versions of sendmail do not have this bug. For those using SunOS | |
1623 4.1, the best fix is to install sendmail V8 or IDA sendmail (which | |
1624 have other advantages over the regular sendmail as well). At the time | |
1625 of this writing, these official versions are available: | |
1626 | |
1627 Sendmail V8 on ftp.cs.berkeley.edu in /ucb/sendmail: | |
1628 sendmail.8.6.9.base.tar.Z (the base system source & documentation) | |
1629 sendmail.8.6.9.cf.tar.Z (configuration files) | |
1630 sendmail.8.6.9.misc.tar.Z (miscellaneous support programs) | |
1631 sendmail.8.6.9.xdoc.tar.Z (extended documentation, with postscript) | |
1632 | |
1633 IDA sendmail on vixen.cso.uiuc.edu in /pub: | |
1634 sendmail-5.67b+IDA-1.5.tar.gz | |
1635 | |
373 | 1636 *** Emacs fails to understand most Internet host names, even though |
124 | 1637 the names work properly with other programs on the same system. |
197 | 1638 Emacs won't work with X-windows if the value of DISPLAY is HOSTNAME:0. |
1639 Gnus can't make contact with the specified host for nntp. | |
0 | 1640 |
124 | 1641 This typically happens on Suns and other systems that use shared |
1642 libraries. The cause is that the site has installed a version of the | |
1643 shared library which uses a name server--but has not installed a | |
1644 similar version of the unshared library which Emacs uses. | |
0 | 1645 |
124 | 1646 The result is that most programs, using the shared library, work with |
1647 the nameserver, but Emacs does not. | |
1648 | |
1649 The fix is to install an unshared library that corresponds to what you | |
1650 installed in the shared library, and then relink Emacs. | |
0 | 1651 |
124 | 1652 On SunOS 4.1, simply define HAVE_RES_INIT. |
1653 | |
1654 If you have already installed the name resolver in the file libresolv.a, | |
1655 then you need to compile Emacs to use that library. The easiest way to | |
1656 do this is to add to config.h a definition of LIBS_SYSTEM, LIBS_MACHINE | |
1657 or LIB_STANDARD which uses -lresolv. Watch out! If you redefine a macro | |
1658 that is already in use in your configuration to supply some other libraries, | |
1659 be careful not to lose the others. | |
1660 | |
1661 Thus, you could start by adding this to config.h: | |
1662 | |
1663 #define LIBS_SYSTEM -lresolv | |
1664 | |
1665 Then if this gives you an error for redefining a macro, and you see that | |
1666 the s- file defines LIBS_SYSTEM as -lfoo -lbar, you could change config.h | |
1667 again to say this: | |
1668 | |
1669 #define LIBS_SYSTEM -lresolv -lfoo -lbar | |
1670 | |
373 | 1671 *** With process-connection-type set to t, each line of subprocess |
1672 output is terminated with a ^M, making ange-ftp and GNUS not work. | |
1673 | |
1674 On SunOS systems, this problem has been seen to be a result of an | |
1675 incomplete installation of gcc 2.2 which allowed some non-ANSI | |
1676 compatible include files into the compilation. In particular this | |
1677 affected virtually all ioctl() calls. | |
1678 | |
1679 | |
1680 ** Linux | |
845 | 1681 *** XEmacs crashes on startup, in make-frame. |
1682 | |
1683 Typically the Lisp backtrace includes | |
1684 | |
1685 make-frame(nil #<x-device on ":0.0" 0x2558>) | |
1686 | |
2648 | 1687 somewhere near the top. The problem is due to an improvement in GNU ld |
1688 that sorts the ELF reloc sections in the executable, giving dramatic | |
1689 speedups in startup for large executables. It also confuses the | |
1690 traditional unexec code in XEmacs, leading to the core dump. The | |

1691 solution is to use the --with-pdump or --with-ldflags='-z nocombreloc' |
2648 | 1692 options to configure. Recent 21.4 and 12.5 autodetect this in |
1693 configure. | |
845 | 1694 |
1695 Red Hat and SuSE (at least) distributed a prerelease version of ld | |
1696 (versions around 2.11.90.x.y) where autodetection is impossible. The | |
1697 recommended procedure is to upgrade to binutils >= 2.12 and rerun | |

1698 configure. Otherwise you must apply the flags by hand. --with-pdump |
2648 | 1699 is recommended. |
448 | 1700 |
1701 *** I want XEmacs to use the Alt key, not the XXX key, for Meta commands | |
1702 | |
1703 For historical reasons, XEmacs looks for a Meta key, then an Alt key. | |
1704 It binds Meta commands to the X11 modifier bit attached to the first | |
1705 of these it finds. On PCs, the Windows key is often assigned the Meta | |
1706 bit, but many desktop environments go to great lengths to get all apps | |
1707 to use the Alt key, and reserve the Windows key to (sensibly enough) | |
1708 the window manager. | |
1709 | |
1710 One correct way to implement this was suggested on comp.emacs.xemacs | |
1711 (by Kilian Foth and in more detail by Michael Piotrowski): unmap the | |
1712 Meta modifier using xmodmap or xkb, and then map the Meta/Windows key | |
450 | 1713 to the Super or Hyper keysym and an appropriate mod bit. XEmacs will |
1714 not find the Meta keysym, and default to using the Alt key for Meta | |
1715 keybindings. Typically few applications use the (X11) Meta modifier; | |
1716 it is tedious but not too much so to teach the ones you need to use | |
1717 Super instead of Meta. There may be further useful hints in the | |
1718 discussion of keymapping on non-Linux platforms. | |
1719 | |
1720 *** The color-gcc wrapper | |
1721 | |
1722 This wrapper colorizes the error messages from gcc. By default XEmacs | |
1723 does not interpret the escape sequences used to generate colors, | |
1724 resulting in a cluttered, hard-to-read buffer. You can remove the | |
1725 wrapper, or defeat the wrapper colorization in Emacs process buffers | |
1726 by editing the "nocolor" attribute in /etc/colorgccrc: | |
1727 | |
1728 $ diff -u /etc/colorgccrc.old /etc/colorgccrc | |
1729 --- /etc/colorgccrc.old Tue Dec 26 02:17:46 2000 | |

1731 @@ -34,1 +34,1 @@ | |
1732 -nocolor: dumb | |
1733 +nocolor: dumb emacs | |
1734 | |
1735 If you want colorization in your Emacs buffers, you may get good | |
1736 results from the ansi-color.el library: | |
1737 | |
1738 http://www.geocities.com/kensanata/color-emacs.html#ansicolors | |
1739 | |
1740 This is written for the mainline GNU Emacs but the author has made | |
1741 efforts to adapt it to XEmacs. YMMV. | |
448 | 1742 |
373 | 1743 *** Slow startup on Linux. |
1744 | |
1745 People using systems based on the Linux kernel sometimes report that | |
448 | 1746 startup takes 10 to 15 seconds longer than `usual'. There are two |
1747 problems, one older, one newer. | |
1748 | |
1749 **** Old problem: IPv4 host lookup | |
373 | 1750 |
448 | 1751 On older systems, this is because Emacs looks up the host name when it |
1752 starts. Normally, this takes negligible time; the extra delay is due | |
1753 to improper system configuration. (Recent Linux distros usually have | |
1754 this configuration correct "out of the box".) This problem can occur | |
1755 for both networked and non-networked machines. | |
373 | 1756 |
1757 Here is how to fix the configuration. It requires being root. | |
1758 | |
448 | 1759 ***** Networked Case |
373 | 1760 |
1761 First, make sure the files `/etc/hosts' and `/etc/host.conf' both | |
1762 exist. The first line in the `/etc/hosts' file should look like this | |
1763 (replace HOSTNAME with your host name): | |
1764 | |
1765 127.0.0.1 localhost HOSTNAME | |
1766 | |
1767 Also make sure that the `/etc/host.conf' files contains the following | |
1768 lines: | |
1769 | |
454 | 1770 order hosts, bind |
373 | 1771 multi on |
1772 | |
1773 Any changes, permanent and temporary, to the host name should be | |
1774 indicated in the `/etc/hosts' file, since it acts a limited local | |
1775 database of addresses and names (e.g., some SLIP connections | |
1776 dynamically allocate ip addresses). | |
1777 | |
448 | 1778 ***** Non-Networked Case |
373 | 1779 |
1780 The solution described in the networked case applies here as well. | |
1781 However, if you never intend to network your machine, you can use a | |
1782 simpler solution: create an empty `/etc/host.conf' file. The command | |
1783 `touch /etc/host.conf' suffices to create the file. The `/etc/hosts' | |
1784 file is not necessary with this approach. | |
1785 | |
448 | 1786 **** New problem: IPv6 CNAME lookup |
1787 | |
1788 A newer problem is due to XEmacs changing to use the modern | |
1789 getaddrinfo() interface from the older gethostbyname() interface. The | |
1790 solution above is insufficient, because getaddrinfo() by default tries | |
1791 to get IPv6 information for localhost. This always involves a dns | |
1792 lookup to get the CNAME, and the strategies above don't work. It then | |
724 | 1793 falls back to IPv4 behavior. This is good[tm] according the people at |
1794 WIDE who know about IPv6. | |
448 | 1795 |
1796 ***** Robust network case | |
1797 | |
1798 Configure your network so that there are no nameservers configured | |
1799 until the network is actually running. getaddrinfo() will not try to | |
1800 access a nameserver that isn't configured. | |
1801 | |
1802 ***** Flaky network case | |
1803 | |
1804 If you have a flaky modem or DSL connection that can be relied on only | |
1805 to go down whenever you want to bring XEmacs up, you need to force | |
1806 IPv4 behavior. Explicitly setting DISPLAY=127.0.0.1:0.0 (or whatever | |
1807 is appropriate) works in most cases. | |
1808 | |
1809 If you cannot or do not want to do that, you can hard code IPv4 | |
1810 behavior in src/process-unix.c. This is bad[tm], on your own head be | |
724 | 1811 it. Use the configure option `--with-ipv6-cname=no'. |
373 | 1812 |
845 | 1813 *** Mandrake |
1814 | |
1815 The Mandrake Linux distribution is attempting to comprehensively | |
1816 update the user interface, and make it consistent across | |
1817 applications. This is very difficult, and will occasionally cause | |
1818 conflicts with applications like Emacs with their own long-established | |
1819 interfaces. Known issues specific to Mandrake or especially common: | |
1820 | |
1821 Some versions of XEmacs (21.1.9 is known) distributed with Mandrake | |
1822 were patched to make the Meta and Alt keysyms synonymous. These | |
1823 normally work as expected in the Mandrake environment. However, | |
1824 custom-built XEmacsen (including all 21.2 betas) will "inexplicably" | |
1825 not respect the "Alt-invokes-Meta-commands" convention. See "I want | |
1826 XEmacs to use the Alt key" below. | |
1827 | |
1828 The color-gcc wrapper (see below) is in common use on the Mandrake | |
1829 platform. | |
1830 | |
1831 *** You get crashes in a non-C locale with Linux GNU Libc 2.0. | |
1832 | |
1833 Internationalization was not the top priority for GNU Libc 2.0. | |
1834 As of this writing (1998-12-28) you may get crashes while running | |
1835 XEmacs in a non-C locale. For example, `LC_ALL=en_US xemacs' crashes | |
1836 while `LC_ALL=C xemacs' runs fine. This happens for example with GNU | |
1837 libc 2.0.7. Installing libintl.a and libintl.h built from gettext | |
1838 0.10.35 and re-building XEmacs solves the crashes. Presumably soon | |
1839 everyone will upgrade to GNU Libc 2.1 and this problem will go away. | |
1840 | |
1841 *** `C-z', or `M-x suspend-emacs' hangs instead of suspending. | |
1842 | |
1843 If you build with `gpm' support on Linux, you cannot suspend XEmacs | |
1844 because gpm installs a buggy SIGTSTP handler. Either compile with | |
1845 `--with-gpm=no', or don't suspend XEmacs on the Linux console until | |
1846 this bug is fixed. | |

1859 SGI ships a really old Xpm library in /usr/lib which does not work at | |
1860 all well with XEmacs. The solution is to install your own copy of the | |
2648 | 1861 latest version of Xpm somewhere and then use the --with-site-includes |
1862 and --with-site-libraries flags to tell configure where to find it. | |

1868 to allocate ptys reliably. | |

1878 ** Digital UNIX/OSF/VMS/Ultrix | |
1879 *** XEmacs crashes on Digital Unix within font-lock, or when dealing | |
1036 | 1880 with large compilation buffers, or in other regex applications. |
373 | 1881 |
1882 The default stack size under Digital Unix is rather small (2M as | |
1883 opposed to Solaris 8M), hosing the regexp code, which uses alloca() | |
1884 extensively, overflowing the stack when complex regexps are used. | |
1885 Workarounds: | |
312 | 1886 |
373 | 1887 1) Increase your stack size, using `ulimit -s 8192' or a (t)csh |
1888 equivalent; | |
1889 | |
1890 2) Recompile regex.c with REGEX_MALLOC defined. | |
1891 | |
1892 *** The `Alt' key doesn't behave as `Meta' when running DECwindows. | |
1893 | |
1894 The default DEC keyboard mapping has the Alt keys set up to generate the | |
1895 keysym `Multi_key', which has a meaning to xemacs which is distinct from that | |
1896 of the `Meta_L' and `Meta-R' keysyms. A second problem is that certain keys | |
1897 have the Mod2 modifier attached to them for no adequately explored reason. | |
1898 The correct fix is to pass this file to xmodmap upon starting X: | |
1899 | |
1900 clear mod2 | |
1901 keysym Multi_key = Alt_L | |
1902 add mod1 = Alt_L | |
1903 add mod1 = Alt_R | |

1905 *** The Compose key on a DEC keyboard does not work as Meta key. | |

1910 | |
1911 *** `expand-file-name' fails to work on any but the machine you dumped | |
1912 Emacs on. | |
1913 | |
1914 On Ultrix, if you use any of the functions which look up information | |
1915 in the passwd database before dumping Emacs (say, by using | |
1916 expand-file-name in site-init.el), then those functions will not work | |
1917 in the dumped Emacs on any host but the one Emacs was dumped on. | |
1918 | |
1919 The solution? Don't use expand-file-name in site-init.el, or in | |
1920 anything it loads. Yuck - some solution. | |
1921 | |
1922 I'm not sure why this happens; if you can find out exactly what is | |
1923 going on, and perhaps find a fix or a workaround, please let us know. | |
1924 Perhaps the YP functions cache some information, the cache is included | |
1925 in the dumped Emacs, and is then inaccurate on any other host. | |

1928 ** HP-UX | |
1929 *** I get complaints about the mapping of my HP keyboard at startup, | |
1930 but I haven't changed anything. | |
1931 | |
1932 The default HP keymap is set up to have Mod1 assigned to two different keys: | |
1933 Meta_L and Mode_switch (even though there is not actually a Mode_switch key on | |
1934 the keyboard -- it uses an "imaginary" keycode.) There actually is a reason | |
1935 for this, but it's not a good one. The correct fix is to execute this command | |
1936 upon starting X: | |
1937 | |
1938 xmodmap -e 'remove mod1 = Mode_switch' | |

1945 I get a very strange problem when linking libc.a dynamically: every | |
1946 event (mouse, keyboard, expose...) results in a "poll: Interrupted | |
1947 system call" message in the window where XEmacs was | |
1948 launched. Forcing a static link of libc.a alone by adding | |
1949 /usr/lib/libc.a at the end of the link line solves this. Note that | |
1950 my 9.07 build of 19.14b17 and my (old) build of 19.13 both exhibit | |
442 | 1951 the same behavior. I've tried various hpux patches to no avail. If |
373 | 1952 this problem cannot be solved before the release date, binary kits |
1953 for HP *must* be linked statically against libc, otherwise this | |
1954 problem will show up. (This is directed at whoever will volunteer | |
1955 for this kit, as I won't be available to do it, unless 19.14 gets | |
1956 delayed until mid-june ;-). I think this problem will be an FAQ soon | |

1983 *** XEmacs dumps core at startup when native audio is used. Native | |
1984 audio does not work with recent versions of HP-UX. | |
1985 | |
1986 Under HP-UX 10.20 and later (e.g., HP-UX 11.XX), with native audio | |
1987 enabled, the dumped XEmacs binary ("xemacs") core dumps at startup if | |
1988 recent versions of the libAlib.sl audio shared library is used. Note | |
1989 that "temacs" will run, but "xemacs" will dump core. This, of course, | |
1990 causes the XEmacs build to fail. If GNU malloc is enabled, a stack | |
1991 trace will show XEmacs to have crashed in the "first" call to malloc(). | |
1992 | |
1993 This bug currently exists in all versions of XEmacs, when the undump | |
1994 mechanism is used. It is not known if using the experimental portable | |
1995 dumper will allow native audio to work. | |
1996 | |
1997 **** Cause: | |
1998 | |
1999 Recent versions of the HP-UX 10.20 (and later) audio shared library (in | |
2000 /opt/audio/lib), pulls in the libdce shared library, which pulls in a | |
2001 thread (libcma) library. This prevents the HP-UX undump() routine (in | |
2002 unexhp9k800.c) from properly working. What's happening is that some | |
2003 initialization routines are being called in the libcma library, *BEFORE* | |
2004 main() is called, and these initialization routines are calling | |
2005 malloc(). Unfortunately, in order for the undumper to work, XEmacs must | |
2006 adjust (move upwards) the sbrk() value *BEFORE* the first call to | |
2007 malloc(); if malloc() is called before XEmacs has properly adjusted sbrk | |
2008 (which is what is happening), dumped memory that is being used by | |
2009 XEmacs, is improperly re-allocated for use by malloc() and the dumped | |
2010 memory is corrupted. This causes XEmacs to die an horrible death. | |
2011 | |
2012 It is believed that versions of the audio library past December 1998 | |
2013 will trigger this problem. Under HP-UX 10.20, you probably have to | |
2014 install audio library patches to encounter this. It's probable that | |
2015 recent "fresh, out-of-the-box" HP-UX 11.XX workstations also have this | |
2016 problem. For HP-UX 10.20, it's believed that audio patch PHSS_17121 (or | |
2017 a superceeding one, like PHSS_17554, PHSS_17971, PHSS_18777, PHSS_21481, | |
2018 or PHSS_21662, etc.) will trigger this. | |
2019 | |
2020 To check if your audio library will cause problems for XEmacs, run | |
2021 "chatr /opt/audio/lib/libAlib.sl". If "libdce" appears in the displayed | |
2022 shared library list, XEmacs will probably encounter problems if audio is | |
2023 enabled. | |
2024 | |
2025 **** Workaround: | |
2026 | |
2027 Don't enable native audio. Re-run configure without native audio | |
2028 support. | |
2029 | |
2030 If your site supports it, try using NAS (Network Audio Support). | |
2031 | |
2032 Try using the experimental portable dumper. It may work, or it may | |
2033 not. | |

2035 | |
373 | 2036 *** `Pid xxx killed due to text modification or page I/O error' |
2037 | |
2038 On HP-UX, you can get that error when the Emacs executable is on an NFS | |
2039 file system. HP-UX responds this way if it tries to swap in a page and | |
2040 does not get a response from the server within a timeout whose default | |
2041 value is just ten seconds. | |
2042 | |
2043 If this happens to you, extend the timeout period. | |
2044 | |
2045 *** Shell mode on HP-UX gives the message, "`tty`: Ambiguous". | |
124 | 2046 |
2047 christos@theory.tn.cornell.edu says: | |
2048 | |
2049 The problem is that in your .cshrc you have something that tries to | |
197 | 2050 execute `tty`. If you are not running the shell on a real tty then tty |
2051 will print "not a tty". Csh expects one word in some places, but tty | |
2052 is giving it back 3. | |
124 | 2053 |
197 | 2054 The solution is to add a pair of quotes around `tty` to make it a |
2055 single word: | |
0 | 2056 |
454 | 2057 if (`tty` == "/dev/console") |
124 | 2058 |
2059 should be changed to: | |
2060 | |
454 | 2061 if ("`tty`" == "/dev/console") |
124 | 2062 |
2063 Even better, move things that set up terminal sections out of .cshrc | |
2064 and into .login. | |

2072 version 6", SCO 4.2.0h Dev Sys Maintenance Supplement 01/06/93; Quick | |
2073 C Compiler Version 1.00.46 (Beta). The solution is to compile with | |

1332 | 2078 *** Conflicts with FSF NTEmacs |
2079 | |
2080 Depending on how it is installed, FSF NTEmacs may setup various EMACS* | |
2081 variables in your environment. The presence of these variables may | |
2082 cause XEmacs to fail at startup, cause you to see corrupted | |
2083 doc-strings, or cause other random problems. | |
2084 | |
2085 You should remove these variables from your environment. These | |
2086 variables are not required to run FSF NTEmacs if you start it by | |
2087 running emacs.bat. | |
2088 | |
2089 *** XEmacs can't find my init file | |
2090 | |
2091 XEmacs looks for your init in your "home" directory -- either in | |
2092 `~/.xemacs/init.el' or `~/.emacs'. XEmacs decides that your "home" | |
2093 directory is, in order of preference: | |
2094 | |
2095 - The value of the HOME environment variable, if the variable exists. | |
2096 - The value of the registry entry SOFTWARE\XEmacs\XEmacs\HOME, | |
2097 if it exists. | |
2098 - The value of the HOMEDRIVE and HOMEPATH environment variables, if | |
2099 these variables both exist. | |
2100 - C:\. | |
2101 | |
2102 To determine what XEmacs thinks your home directory is, try opening | |
2103 a file in the `~' directory, and you should see its expansion in the | |
2104 modeline. If this doesn't work, type ESC : (user-home-directory). | |
2105 | |
2106 *** XEmacs can't find any packages | |
2107 | |
2108 XEmacs looks for your packages in subdirectories of a directory which | |
2109 is set at compile-time (see `config.inc'), and whose default is | |
2110 `C:\Program Files\XEmacs'. XEmacs also looks in `~/.xemacs', where | |
2111 `~' refers to your home directory (see previous entry). The variable | |
2112 `configure-package-path' holds the actual path that was compiled into | |
2113 your copy of XEmacs. | |
2114 | |
2115 The compile-time default location can be overridden by the EMACSPACKAGEPATH | |
2116 environment variable or by the SOFTWARE\XEmacs\XEmacs\EMACSPACKAGEPATH | |
2117 registry entry. You should check that these variables, if they exist, | |
2118 point to the actual location of your package tree. | |
2119 | |
2120 *** XEmacs doesn't die when shutting down Windows 95 or 98 | |
2121 | |
2122 When shutting down Windows 95 or 98 you may see a dialog that says | |
2123 "xemacs / You must quit this program before you quit Windows". | |
2124 It is safe to | |
2125 "Click OK to quit the program and Windows", | |
2126 but you won't be offered a chance to save any modified XEmacs buffers. | |
2127 | |
2128 *** Key bindings | |
2129 | |
2130 The C-z, C-x, C-c, and C-v keystrokes have traditional uses in both | |
2131 emacs and Windows programs. XEmacs binds these keys to their | |
2132 traditional emacs uses, and provides Windows 3.x style bindings for | |
2133 the Cut, Copy and Paste functions. | |
2134 | |
2135 Function XEmacs binding | |
2136 -------- -------------- | |
2137 Undo C-_ | |
2138 Cut Sh-Del | |
2139 Copy C-Insert | |
2140 Paste Sh-Insert | |
2141 | |
2142 You can rebind keys to make XEmacs more Windows-compatible; for | |
2143 example, to bind C-z to undo: | |
2144 | |
2145 (global-set-key [(control z)] 'undo) | |
2146 | |
2147 Rebindind C-x and C-c is trickier because by default these are prefix | |
2148 keys in XEmacs. See the "Key Bindings" node in the XEmacs manual. | |
2149 | |
2150 *** Behavior of selected regions | |
2151 | |
2152 Use the pending-del package to enable the standard Windows behavior of | |
2153 self-inserting deletes region. | |
2154 | |
2155 *** Limitations on the use of the AltGr key. | |
2156 | |
2157 In some locale and OS combinations you can't generate M-AltGr-key or | |
2158 C-M-AltGr-key sequences at all. | |
2159 | |
2160 To generate C-AltGr-key or C-M-AltGr-key sequences you must use the | |
2161 right-hand Control key and you must press it *after* AltGr. | |
2162 | |
2163 These limitations arise from fundamental problems in the way that the | |
2164 win32 API reports AltGr key events. There isn't anything that XEmacs | |
2165 can do to work round these problems that it isn't already doing. | |
2166 | |
2167 You may want to create alternative bindings if any of the standard | |
2168 XEmacs bindings require you to use some combination of Control or Meta | |
2169 and AltGr. | |
2170 | |
2171 *** Limited support for subprocesses under Windows 9x | |
2172 | |
2173 Attempting to use call-process to run a 16bit program gives a | |
2174 "Spawning child process: Exec format error". For example shell-command | |
2175 fails under Windows 95 and 98 if you use command.com or any other | |
2176 16bit program as your shell. | |
2177 | |
2178 XEmacs may incorrectly quote your call-process command if it contains | |
2179 double quotes, backslashes or spaces. | |
2180 | |
2181 start-process and functions that rely on it are supported under Windows 95, | |
2182 98 and NT. However, starting a 16bit program that requires keyboard input | |
2183 may cause XEmacs to hang or crash under Windows 95 and 98, and will leave | |
2184 the orphaned 16bit program consuming all available CPU time. | |
2185 | |
2186 Sending signals to subprocesses started by call-process or by | |
2187 start-process fails with a "Cannot send signal to process" error under | |
2188 Windows 95 and 98. As a side effect of this, quitting XEmacs while it | |
2189 is still running subprocesses causes it to crash under Windows 95 and | |
2190 98. | |

2202 cygXpm-noX4 is part of the cygwin distribution under libraries or | |

2205 | |
524 | 2206 *** Subprocesses do not work. |
2207 | |
2208 You do not have "tty" in your CYGWIN environment variable. This must | |

2210 as it must be read before the cygwin DLL initializes. | |
2211 | |
2212 *** ^G does not work on hung subprocesses. | |
124 | 2213 |
524 | 2214 This is a known problem. It can be remedied by defining BROKEN_SIGIO |

88 | 2237 |
124 | 2238 There are a few incompatible changes in XEmacs, and these are the |
2239 symptoms. Some of the emacs-lisp code you are running needs to be | |
2240 updated to be compatible with XEmacs. | |
2241 | |
2242 The code should not treat keymaps as arrays (use `define-key', etc.), | |
2243 should not use obsolete variables like `unread-command-char' (use | |
197 | 2244 `unread-command-events'). Many (most) of the new ways of doing things |
124 | 2245 are compatible in GNU Emacs and XEmacs. |
88 | 2246 |
197 | 2247 Modern Emacs packages (Gnus, VM, W3, efs, etc) are written to support |
2248 GNU Emacs and XEmacs. We have provided modified versions of several | |
2249 popular emacs packages (dired, etc) which are compatible with this | |
2250 version of emacs. Check to make sure you have not set your load-path | |
2251 so that your private copies of these packages are being found before | |
2252 the versions in the lisp directory. | |
124 | 2253 |
2254 Make sure that your load-path and your $EMACSLOADPATH environment | |
2255 variable are not pointing at an Emacs18 lisp directory. This will | |
2256 cripple emacs. | |

2264 face-background-pixmap, and face-underline-p. The .elc files | |
2265 generated by version 19.9 will work in 19.6 and 19.8, but older .elc | |
2266 files which contain calls to these functions will not work in 19.9. | |

2268 ** Signaling: (error "Byte code stack underflow (byte compiler bug), pc 38") | |
88 | 2269 |
120 | 2270 This error is given when XEmacs 20 is compiled without MULE support |
88 | 2271 but is attempting to load a .elc which requires MULE support. The fix |
2272 is to rebytecompile the offending file. | |
2273 | |
124 | 2274 ** Signaling: (wrong-type-argument ...) when loading mail-abbrevs |
88 | 2275 |
197 | 2276 The is seen when installing the Insidious Big Brother Data Base (bbdb) |
2277 which includes an outdated copy of mail-abbrevs.el. Remove the copy | |
2278 that comes with bbdb and use the one that comes with XEmacs. | |

2281 * MULE issues | |
197 | 2282 ============= |
144 | 2283 |
223 | 2284 ** A reminder: XEmacs/Mule work does not currently receive *any* |
2285 funding, and all work is done by volunteers. If you think you can | |
2286 help, please contact the XEmacs maintainers. | |
2287 | |
278 | 2288 ** XEmacs/Mule doesn't support TTY's satisfactorily. |
223 | 2289 |
2290 This is a major problem, which we plan to address in a future release | |
2291 of XEmacs. Basically, XEmacs should have primitives to be told | |
2292 whether the terminal can handle international output, and which | |
2293 locale. Also, it should be able to do approximations of characters to | |
2294 the nearest supported by the locale. | |
2295 | |
197 | 2296 ** Internationalized (Asian) Isearch doesn't work. |
144 | 2297 |
2298 Currently, Isearch doesn't directly support any of the input methods | |
2299 that are not XIM based (like egg, canna and quail) (and there are | |
223 | 2300 potential problems with XIM version too...). If you're using egg |
2301 there is a workaround. Hitting <RET> right after C-s to invoke | |
2302 Isearch will put Isearch in string mode, where a complete string can | |
2303 be typed into the minibuffer and then processed by Isearch afterwards. | |
2304 Since egg is now supported in the minibuffer using string mode you can | |
2305 now use egg to input your Japanese, Korean or Chinese string, then hit | |
2306 return to send that to Isearch and then use standard Isearch commands | |
2307 from there. | |
144 | 2308 |
223 | 2309 ** Using egg and mousing around while in 'fence' mode screws up my |
2310 buffer. | |
144 | 2311 |
2312 Don't do this. The fence modes of egg and canna are currently very | |
2313 modal, and messing with where they expect point to be and what they | |
2314 think is the current buffer is just asking for trouble. If you're | |
2315 lucky they will realize that something is awry, and simply delete the | |
2316 fence, but worst case can trash other buffers too. We've tried to | |
2317 protect against this where we can, but there still are many ways to | |
2318 shoot yourself in the foot. So just finish what you are typing into | |
2319 the fence before reaching for the mouse. | |
223 | 2320 |
2321 ** Not all languages in Quail are supported like Devanagari and Indian | |
2322 languages, Lao and Tibetan. | |
2323 | |
2324 Quail requires more work and testing. Although it has been ported to | |
2325 XEmacs, it works really well for Japanese and for the European | |
2326 languages. | |
2327 | |
2328 ** Right-to-left mode is not yet implemented, so languages like | |
2329 Arabic, Hebrew and Thai don't work. | |
2330 | |
2331 Getting this right requires more work. It may be implemented in a | |
2332 future XEmacs version, but don't hold your breath. If you know | |
2333 someone who is ready to implement this, please let us know. | |
2334 | |
2335 ** We need more developers and native language testers. It's extremely | |
2336 difficult (and not particularly productive) to address languages that | |
2337 nobody is using and testing. | |
2338 | |
2339 ** The kWnn and cWnn support for Chinese and Korean needs developers | |
2340 and testers. It probably doesn't work. | |
2341 | |
2342 ** There are no `native XEmacs' TUTORIALs for any Asian languages, | |
454 | 2343 including Japanese. FSF Emacs and XEmacs tutorials are quite similar, |
223 | 2344 so it should be sufficient to skim through the differences and apply |
2345 them to the Japanese version. | |
2346 | |
2347 ** We only have localized menus translated for Japanese, and the | |
2348 Japanese menus are developing bitrot (the Mule menu appears in | |
2349 English). | |
2350 | |
2351 ** XIM is untested for any language other than Japanese. |
