7 This file is rather large, but we have tried to sort the entries by
|
|
|
8 their respective relevance for XEmacs, but may have not succeeded
|
|
|
9 completely in that task. The file is divided into four parts:

16 Use `C-c C-f' to move to the next equal level of outline, and
|
|
223
|
17 `C-c C-b' to move to previous equal level. `C-h m' will give more
|
|
|
18 info about the Outline mode.
|
|
120
|
19
|
|
197
|
20 Also, Try finding the things you need using one of the search commands
|
|
|
21 XEmacs provides (e.g. `C-s').
|
|
|
22
|
|
524
|
23 General advice:
|
|
957
|
24
|
|
524
|
25 WATCH OUT for your init file! (~/.xemacs/init.el or ~/.emacs) If
|
|
|
26 you observe strange problems, invoke XEmacs with the `-vanilla'
|
|
|
27 option and see if you can repeat the problem.
|
|
197
|
28
|
|
957
|
29 Note that most of the problems described here manifest at RUN
|
|
|
30 time, even those described as BUILD problems. It is quite unusual
|
|
|
31 for a released XEmacs to fail to build. So a "build problem"
|
|
|
32 requires you to tweak the build environment, then rebuild XEmacs.
|
|
|
33 A "runtime problem" is one that can be fixed by proper
|
|
|
34 configuration of the existing build. Compatibility problems and
|
|
|
35 Mule issues are generally runtime problems, but are treated
|
|
|
36 separately for convenience.

|
42 ** General
|
|
1245
|
43
|
|
915
|
44 Much general information is in INSTALL. If it's covered in
|
|
|
45 INSTALL, we don't repeat it here.
|
|
|
46
|
|
1098
|
47 *** How do I configure to get the buffer tabs/progress bars?
|
|
915
|
48
|
|
|
49 These features depend on support for "native widgets". Use the
|
|
|
50 --with-widgets option to configure. Configuration of widgets is
|
|
|
51 automatic for "modern" toolkits (MS Windows, GTK, and Motif), but if
|
|
|
52 you are using Xt and the Athena widgets, you will probably want to
|
|
|
53 specify a "3d" widget set. See configure --usage, and don't forget to
|
|
|
54 install the corresponding development libraries.
|
|
|
55
|
|
|
56 *** I know I have libfoo installed, but configure doesn't find it.
|
|
|
57
|
|
|
58 Typical of Linux systems with package managers. To link with a shared
|
|
|
59 library, you only need the shared library. To compile objects that
|
|
|
60 link with it, you need the headers---and distros don't provide them with
|
|
|
61 the libraries. You need the additional "development" package, too.
|
|
|
62
|
|
373
|
63 *** When using gcc, you get the error message "undefined symbol __fixunsdfsi".
|
|
|
64 When using gcc, you get the error message "undefined symbol __main".
|
|
|
65
|
|
|
66 This means that you need to link with the gcc library. It may be called
|
|
|
67 "gcc-gnulib" or "libgcc.a"; figure out where it is, and define LIB_GCC in
|
|
|
68 config.h to point to it.
|
|
|
69
|
|
|
70 It may also work to use the GCC version of `ld' instead of the standard one.
|
|
|
71
|
|
|
72 *** Excessive optimization with pgcc can break XEmacs
|
|
124
|
73
|
|
|
74 It has been reported on some systems that compiling with -O6 can lead
|
|
|
75 to XEmacs failures. The workaround is to use a lower optimization
|
|
|
76 level. -O2 and -O4 have been tested extensively.
|
|
|
77
|
|
229
|
78 All of this depends heavily on the version of pgcc and the version
|
|
|
79 of libc. Snapshots near the release of pgcc-1.0 have been tested
|
|
|
80 extensively and no sign of breakage has been seen on systems using
|
|
|
81 glibc-2.
|
|
|
82
|
|
373
|
83 *** src/Makefile and lib-src/Makefile are truncated--most of the file missing.
|
|
229
|
84
|
|
373
|
85 This can happen if configure uses GNU sed version 2.03. That version
|
|
|
86 had a bug. GNU sed version 2.05 works properly.
|
|
124
|
87
|
|
373
|
88 *** When compiling with X11, you get "undefined symbol _XtStrings".
|
|
124
|
89
|
|
373
|
90 This means that you are trying to link emacs against the X11r4 version of
|
|
|
91 libXt.a, but you have compiled either Emacs or the code in the lwlib
|
|
|
92 subdirectory with the X11r5 header files. That doesn't work.
|
|
124
|
93
|
|
373
|
94 Remember, you can't compile lwlib for r4 and emacs for r5, or vice versa.
|
|
|
95 They must be in sync.
|
|
124
|
96
|
|
373
|
97 *** test-distrib says that the distribution has been clobbered
|
|
197
|
98 or, temacs prints "Command key out of range 0-127"
|
|
|
99 or, temacs runs and dumps xemacs, but xemacs totally fails to work.
|
|
|
100 or, temacs gets errors dumping xemacs
|
|
|
101
|
|
|
102 This can be because the .elc files have been garbled. Do not be
|
|
|
103 fooled by the fact that most of a .elc file is text: these are binary
|
|
|
104 files and can contain all 256 byte values.
|
|
|
105
|
|
|
106 In particular `shar' cannot be used for transmitting GNU Emacs. It
|
|
|
107 typically truncates "lines". (this does not apply to GNU shar, which
|
|
|
108 uses uuencode to encode binary files.)
|
|
|
109
|
|
|
110 If you have a copy of Emacs that has been damaged in its nonprinting
|
|
|
111 characters, you can fix them by running:
|
|
|
112
|
|
|
113 make all-elc
|
|
|
114
|
|
|
115 This will rebuild all the needed .elc files.
|
|
|
116
|
|
1318
|
117 ** Intel Architecture General
|
|
|
118
|
|
|
119 *** Don't use -O2 or -O3 with Cygwin 1.0, CodeFusion-99070 or gcc 2.7.2 on x86
|
|
|
120 without also using `-fno-strength-reduce'.
|
|
|
121
|
|
|
122 gcc will generate incorrect code otherwise. This bug is present in at
|
|
|
123 least 2.6.x and 2.7.[0-2]. This bug has been fixed in GCC 2.7.2.1 and
|
|
|
124 later. This bug is O/S independent, but is limited to x86 architectures.
|
|
|
125
|
|
|
126 This problem is known to be fixed in egcs (or pgcc) 1.0 or later.
|
|
|
127
|
|
|
128 Unfortunately, later releases of Cygnus-released compilers (not the
|
|
|
129 Net-released ones) have a bug with the same `problem signature'.
|
|
|
130
|
|
|
131 If you're lucky, you'll get an error while compiling that looks like:
|
|
|
132
|
|
|
133 event-stream.c:3189: internal error--unrecognizable insn:
|
|
|
134 (insn 256 14 15 (set (reg/v:SI 24)
|
|
|
135 (minus:SI (reg/v:SI 25)
|
|
|
136 (const_int 2))) -1 (insn_list 11 (nil))
|
|
|
137 (nil))
|
|
|
138 0 0 [main]
|
|
|
139
|
|
|
140 If you're unlucky, your code will simply execute incorrectly.
|
|
|
141
|
|
|
142 *** Don't use -O2 with gcc 2.7.2 under Intel architectures without also
|
|
|
143 using `-fno-caller-saves'.
|
|
|
144
|
|
|
145 gcc will generate incorrect code otherwise. This bug is still
|
|
|
146 present in gcc 2.7.2.3. There have been no reports to indicate the
|
|
|
147 bug is present in egcs 1.0 (or pgcc 1.0) or later. This bug is O/S
|
|
|
148 independent, but limited to x86 architectures.
|
|
|
149
|
|
|
150 This problem is known to be fixed in egcs (or pgcc) 1.0 or later.
|
|
|
151
|
|
373
|
152 *** `compress' and `uncompress' not found and XFree86
|
|
|
153
|
|
|
154 XFree86 installs a very old version of libz.a by default ahead of where
|
|
|
155 more modern version of libz might be installed. This will cause problems
|
|
|
156 when attempting to link against libMagick. The fix is to remove the old
|
|
|
157 libz.a in the X11 binary directory.
|
|
|
158
|
|
|
159
|
|
1245
|
160 ** Motif
|
|
|
161
|
|
|
162 Motif is the X11 version of the Gnus torture test: if there's a way to
|
|
|
163 crash, Motif will find it. With the open source release of Motif, it
|
|
|
164 seems like a good idea to collect all Motif-related issues in one
|
|
|
165 place.
|
|
|
166
|
|
|
167 You should also look in your OS's section, as it may not be Motif's
|
|
|
168 fault.
|

|
|
195 backtraces have also been observed on HP/UX and Solaris. There is a
|
|
|

250 Unfortunately, XEmacs releases prior to 21.0 don't work with

|

254

287 *** IBM compiler fails: "The character # is not a valid C source character."
|
|
|
288
|
|
|
289 Most recently observed in 21.5.9, due to USE_KKCC ifdefs (they just
|
|
|
290 happen to tickle the implementation).

|
291
|
|
|
292 Valdis Kletnieks says:
|
|
|
293
|
|
|
294 The problem is that IBM defines a *MACRO* called 'memcpy', and we
|
|
|
295 have stuck a #ifdef/#endif inside the macro call. As a workaround,
|
|
|
296 try adding '-U__STR__' to your CFLAGS - this will cause string.h to
|
|
|
297 not do a #define for strcpy() to __strcpy() - it uses this for
|
|
|
298 automatic inlining support.
|
|
|
299
|
|
|
300 (For the record, the same issue affects a number of other functions
|

301 defined in string.h - basically anything the compiler knows how to
|
|

302 inline.)

|
312 <IX89470>: LIBXT.A INCORRECT HANDLING OF EXCEPTIONS IN XTAPPADDINPUT
|
|
|
313
|
|
|
314 The solution is to install X11.base.lib at version >=4.3.2.5.

315
|
|
373
|
316 *** On AIX, you get this compiler error message:

319 1501-106: (S) Include file X11/Xlib.h not found.
|
|
|
320
|
|
|
321 This means your system was installed with only the X11 runtime i.d
|
|
|
322 libraries. You have to find your sipo (bootable tape) and install
|
|
|
323 X11Dev... with smit.

|
327 of archive /usr/lib/libIM.a, was not defined in archive member shr.o.
|
|
|
328
|
|
|
329 This is a problem in libIM.a. You can work around it by executing
|
|
|
330 these shell commands in the src subdirectory of the directory where
|
|
|
331 you build Emacs:
|
|
|
332
|
|
|
333 cp /usr/lib/libIM.a .
|
|
|
334 chmod 664 libIM.a
|
|
|
335 ranlib libIM.a
|
|
|
336
|
|
|
337 Then change -lIM to ./libIM.a in the command to link temacs (in
|
|
|
338 Makefile).

|
|
369 are caused by using GNU ld. There are several workarounds available:
|
|
|
370
|
|
|
371 In XEmacs 21.2 or later, configure using the new portable dumper
|
|
|
372 (--pdump).
|
|
|
373
|
|
|
374 Alternatively, you can link using the Sun version of ld, which is
|
|
|
375 normally held in /usr/ccs/bin. This can be done by one of:
|
|
|
376
|
|
|
377 - building gcc with these configure flags:
|
|
|
378 configure --with-ld=/usr/ccs/bin/ld --with-as=/usr/ccs/bin/as
|
|
|
379
|
|
|
380 - adding -B/usr/ccs/bin/ to CFLAGS used to configure XEmacs
|
|
|
381 (Note: The trailing '/' there is significant.)
|
|
|
382
|
|
|
383 - uninstalling GNU ld.

385 The Solaris2 FAQ claims:
|
|
|
386
|
|
|
387 When you install gcc, don't make the mistake of installing
|
|
|
388 GNU binutils or GNU libc, they are not as capable as their
|
|
|
389 counterparts you get with Solaris 2.x.
|
|
|
390
|
|
373
|
391 *** Link failure when using acc on a Sun.
|
|
|
392
|
|
|
393 To use acc, you need additional options just before the libraries, such as
|
|
|
394
|
|
|
395 /usr/lang/SC2.0.1/values-Xt.o -L/usr/lang/SC2.0.1/cg87 -L/usr/lang/SC2.0.1
|
|
|
396
|
|
|
397 and you need to add -lansi just before -lc.
|
|
|
398
|
|
|
399 The precise file names depend on the compiler version, so we
|
|
|
400 cannot easily arrange to supply them.

|
402 *** Problems finding X11 libraries on Solaris with Openwindows
|
|
|
403
|
|
|
404 Some users have reported problems in this area. The reported solution
|
|
|
405 is to define the environment variable OPENWINHOME, even if you must set
|
|
|
406 it to `/usr/openwin'.

|
|
407
|
|
|
408 *** Sed problems on Solaris 2.5
|
|
|
409
|
|
|
410 There have been reports of Sun sed truncating very lines in the
|
|
|
411 Makefile during configuration. The workaround is to use GNU sed or,
|
|
454
|
412 even better, think of a better way to generate Makefile, and send us a
|
|
373
|
413 patch. :-)

|
|
|
415 *** On Solaris 2 I get undefined symbols from libcurses.a.
|
|
|
416
|
|
|
417 You probably have /usr/ucblib/ on your LD_LIBRARY_PATH. Do the link with
|
|
|
418 LD_LIBRARY_PATH unset. Generally, avoid using any ucb* stuff when
|
|
|
419 building XEmacs.
|
|
|
420
|
|
|
421 *** On Solaris 2 I cannot make alloc.o, glyphs.o or process.o.
|
|
|
422
|
|
|
423 The SparcWorks C compiler may have difficulty building those modules
|
|
|
424 with optimization level -xO4. Try using only "-fast" optimization
|
|
|
425 for just those modules. (Or use gcc).
|

|
426
|
|
|
427 *** Solaris 2.3 /bin/sh coredumps during configuration.
|
|
|
428
|
|
|
429 This only occurs if you have LANG != C. This is a known bug with
|
|
|
430 /bin/sh fixed by installing Patch-ID# 101613-01. Or, you can use
|
|
1697
|
431 bash by setting the environment variable CONFIG_SHELL to /bin/bash
|
|
|
432
|
|
|
433 *** Solaris 2.x configure fails: ./config.status: test: argument expected
|
|
|
434
|
|
|
435 This is a known bug with /bin/sh and /bin/test, i.e. they do not
|
|
|
436 support the XPG4 standard. You can use bash as a workaround or an
|
|
|
437 XPG4-compliant Bourne shell such as the Sun-supplied /usr/xpg4/bin/sh
|
|
|
438 by setting the environment variable CONFIG_SHELL to /usr/xpg4/bin/sh
|
|
373
|
439
|
|
|
440 *** On SunOS, you get linker errors
|
|
454
|
441 ld: Undefined symbol
|
|
373
|
442 _get_wmShellWidgetClass
|
|
|
443 _get_applicationShellWidgetClass
|
|
|
444
|
|
|
445 The fix to this is to install patch 100573 for OpenWindows 3.0
|
|
|
446 or link libXmu statically.
|
|
|
447
|
|
|
448 *** On Sunos 4, you get the error ld: Undefined symbol __lib_version.
|
|
|
449
|
|
|
450 This is the result of using cc or gcc with the shared library meant
|
|
|
451 for acc (the Sunpro compiler). Check your LD_LIBRARY_PATH and delete
|
|
|
452 /usr/lang/SC2.0.1 or some similar directory.
|
|
|
453
|
|
|
454 *** Undefined symbols when linking on Sunos 4.1.
|
|
|
455
|
|
|
456 If you get the undefined symbols _atowc _wcslen, _iswprint, _iswspace,
|
|
|
457 _iswcntrl, _wcscpy, and _wcsncpy, then you need to add -lXwchar after
|
|
|
458 -lXaw in the command that links temacs.
|
|
|
459
|
|
|
460 This problem seems to arise only when the international language
|
|
|
461 extensions to X11R5 are installed.
|
|
|
462
|
|
|
463 *** On a Sun running SunOS 4.1.1, you get this error message from GNU ld:
|
|
|
464
|
|
454
|
465 /lib/libc.a(_Q_sub.o): Undefined symbol __Q_get_rp_rd referenced from text segment
|
|
373
|
466
|
|
|
467 The problem is in the Sun shared C library, not in GNU ld.
|
|
|
468
|
|
|
469 The solution is to install Patch-ID# 100267-03 from Sun.
|
|
|
470
|
|
|
471 *** SunOS 4.1.2: undefined symbol _get_wmShellWidgetClass
|
|
|
472
|
|
|
473 Apparently the version of libXmu.so.a that Sun ships is hosed: it's missing
|
|
454
|
474 some stuff that is in libXmu.a (the static version). Sun has a patch for
|
|
373
|
475 this, but a workaround is to use the static version of libXmu, by changing
|
|
|
476 the link command from "-lXmu" to "-Bstatic -lXmu -Bdynamic". If you have
|
|
|
477 OpenWindows 3.0, ask Sun for these patches:
|
|
|
478 100512-02 4.1.x OpenWindows 3.0 libXt Jumbo patch
|
|
|
479 100573-03 4.1.x OpenWindows 3.0 undefined symbols with shared libXmu

|

|
|
481 *** Random other SunOS 4.1.[12] link errors.
|
|
|
482

|
|
483 The X headers and libraries that Sun ships in /usr/{include,lib}/X11 are
|

568 There are a couple of problems [with use of -rpath with Irix ld], though:
|
|
|
569
|
|
|
570 1. The ld in IRIX 5.3 ignores all but the last -rpath
|
|
|
571 spec, so the patched configure spits out a warning
|
|
|
572 if --x-libraries or --site-runtime-libraries are
|
|
454
|
573 specified under irix 5.x, and it only adds -rpath

574 entries for the --site-runtime-libraries. This bug was

575 fixed sometime between 5.3 and 6.2.
|
|
|
576
|
|
|
577 2. IRIX gcc 2.7.2 doesn't accept -rpath directly, so
|
|
|
578 it would have to be prefixed by -Xlinker or "-Wl,".
|
|
|
579 This would be fine, except that configure compiles with

580 ${CC-cc} $CFLAGS $LDFLAGS ...
|
|
|
581 rather than quoting $LDFLAGS with prefix-args, like
|
|
|
582 src/Makefile does. So if you specify --x-libraries

615 My versions are XEmacs 20.3 (problem first noted in 19.15) and IRIX
|
|
|
616 6.2, compiled using -n32. I'd guess that the relevant individual
|
|
|
617 patch was "SG0002580: multiple fixes for X libraries". SGI recommends

618 that the complete patch set be installed rather than parts of it.

620 ** Digital UNIX/OSF/VMS

|
|
621 *** On Digital UNIX, the DEC C compiler might have a problem compiling
|
|
197
|
622 some files.
|
|
124
|
623
|
|
|
624 In particular, src/extents.c and src/faces.c might cause the DEC C
|
|
|
625 compiler to abort. When this happens: cd src, compile the files by
|
|
|
626 hand, cd .., and redo the "make" command. When recompiling the files by
|
|
|
627 hand, use the old C compiler for the following versions of Digital UNIX:
|
|
|
628 - V3.n: Remove "-migrate" from the compile command.
|
|
|
629 - V4.n: Add "-oldc" to the compile command.
|
|
|
630
|
|

|
631 A related compiler bug has been fixed by the DEC compiler team. The
|
|
|
632 new versions of the compiler should run fine.

635 optimization but will crash randomly if built with optimization.
|
|

636

|
|
637 Using 'cc -g' is not sufficient to eliminate all optimization. Try
|
|
|
638 'cc -g -O0' instead.

|

640 *** Compilation errors on VMS.

|
|

681 *** Native cc on SCO OpenServer 5 is now OK. Icc may still throw you
|
|
197
|
682 a curve. Here is what Robert Lipe <robertl@arnet.com> says:
|
|
124
|
683
|
|
454
|
684 Unlike XEmacs 19.13, building with the native cc on SCO OpenServer 5
|
|
124
|
685 now produces a functional binary. I will typically build this
|
|
|
686 configuration for COFF with:
|
|
|
687
|
|
197
|
688 /path_to_xemacs_source/configure --with-gcc=no \
|
|
124
|
689 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
690 --with-xpm --with-xface --with-sound=nas
|
|
|
691
|
|
454
|
692 This version now supports ELF builds. I highly recommend this to
|
|
|
693 reduce the in-core footprint of XEmacs. This is now how I compile
|
|
124
|
694 all my test releases. Build it like this:
|
|
|
695
|
|
|
696 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
|
697 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
698 --with-xpm --with-xface --with-sound=nas --dynamic
|
|
|
699
|
|
454
|
700 The compiler known as icc [ supplied with the OpenServer 5 Development
|
|
124
|
701 System ] generates a working binary, but it takes forever to generate
|
|
|
702 XEmacs. ICC also whines more about the code than /bin/cc does. I do
|
|
|
703 believe all its whining is legitimate, however. Note that you do
|
|
|
704 have to 'cd src ; make LD=icc' to avoid linker errors.
|
|
|
705
|
|
|
706 The way I handle the build procedure is:
|
|
|
707
|
|
|
708 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
|
709 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
710 --with-xpm --with-xface --with-sound=nas --dynamic --compiler="icc"
|
|
|
711
|
|
454
|
712 NOTE I have the xpm, xface, and audio libraries and includes in
|
|
124
|
713 /usr/local/lib, /usr/local/include. If you don't have these,
|
|
|
714 don't include the "--with-*" arguments in any of my examples.
|
|
|
715
|
|
454
|
716 In previous versions of XEmacs, you had to override the defaults while
|
|
124
|
717 compiling font-lock.o and extents.o when building with icc. This seems
|
|
|
718 to no longer be true, but I'm including this old information in case it
|
|
|
719 resurfaces. The process I used was:
|
|
|
720
|
|
454
|
721 make -k
|
|
|
722 [ procure pizza, beer, repeat ]
|
|
124
|
723 cd src
|
|
|
724 make CC="icc -W0,-mP1COPT_max_tree_size=3000" font-lock.o extents.o
|
|
|
725 make LD=icc
|
|
|
726
|
|
454
|
727 If you want sound support, get the tls566 supplement from
|
|
|
728 ftp.sco.com:/TLS or any of its mirrors. It works just groovy
|
|
124
|
729 with XEmacs.
|
|
|
730
|
|
|
731 The M-x manual-entry is known not to work. If you know Lisp and would
|
|
|
732 like help in making it work, e-mail me at <robertl@dgii.com>.
|
|
|
733 (UNCHECKED for 19.15 -- it might work).
|
|
|
734
|
|
454
|
735 In earlier releases, gnuserv/gnuclient/gnudoit would open a frame
|
|
124
|
736 just fine, but the client would lock up and the server would
|
|
454
|
737 terminate when you used C-x # to close the frame. This is now
|
|
124
|
738 fixed in XEmacs.
|
|
|
739
|
|
|
740 In etc/ there are two files of note. emacskeys.sco and emacsstrs.sco.
|
|
|
741 The comments at the top of emacskeys.sco describe its function, and
|
|
|
742 the emacstrs.sco is a suitable candidate for /usr/lib/keyboard/strings
|
|
|
743 to take advantage of the keyboard map in emacskeys.sco.
|
|
|
744
|
|
373
|
745 Note: Much of the above entry is probably not valid for XEmacs 21.0

758 Cygwin distribution (http://www.cygwin.com/), which also provides a

759 complete Unix emulation environment (and thus makes ports of Unix

760 utilities nearly trivial). Another implementation is that from MinGW

801 the Cygwin utilities specify explicitly whether they want binary or

803 the mount type.) To fix this, you just need to run the appropriate

838 fix this, do `M-x byte-recompile-directory' and specify the directory

862 and notes that you need to add an element (often "-u") to

|
|
864 needed flag with `man ftp' or other local documentation.

|
|

870 One program known to set TMPDIR and manifest this problem is exmh.

|
876 *** You type Control-H (Backspace) expecting to delete characters.
|
|
124
|
877
|
|
|
878 Emacs has traditionally used Control-H for help; unfortunately this
|
|
424
|
879 interferes with its use as Backspace on TTY's. As of XEmacs 21,
|
|
|
880 XEmacs looks at the "erase" setting of TTY structures and maps C-h to
|
|
|
881 backspace when erase is set to C-h. This is sort of a special hack,
|
|
|
882 but it makes it possible for you to use the standard:
|
|
|
883
|
|
|
884 stty erase ^H
|
|
355
|
885
|
|
424
|
886 to get your backspace key to erase characters. The erase setting is
|
|
|
887 recorded in the Lisp variable `tty-erase-char', which you can use to
|
|
|
888 tune the settings in your .emacs.
|
|
124
|
889
|
|
424
|
890 A major drawback of this is that when C-h becomes backspace, it no
|
|
|
891 longer invokes help. In that case, you need to use f1 for help, or
|
|
|
892 bind another key. An example of the latter is the following code,
|
|
|
893 which moves help to Meta-? (ESC ?):
|
|
124
|
894
|
|
424

|
911 use the ISO10646-1 font registry (or a Cmap or something).

912
|

919 *** Mail agents (VM, Gnus, rmail) cannot get new mail
|
|
197
|
920
|
|
|
921 rmail and VM get new mail from /usr/spool/mail/$USER using a program
|
|
|
922 called `movemail'. This program interlocks with /bin/mail using the
|
|
|
923 protocol defined by /bin/mail.
|
|
|
924
|
|
|
925 There are two different protocols in general use. One of them uses
|
|
|
926 the `flock' system call. The other involves creating a lock file;
|
|
|
927 `movemail' must be able to write in /usr/spool/mail in order to do
|
|
|
928 this. You control which one is used by defining, or not defining, the
|
|
|
929 macro MAIL_USE_FLOCK in config.h or the m- or s- file it includes. IF
|
|
|
930 YOU DON'T USE THE FORM OF INTERLOCKING THAT IS NORMAL ON YOUR SYSTEM,
|
|
|
931 YOU CAN LOSE MAIL!
|
|
|
932
|
|
|
933 If your system uses the lock file protocol, and fascist restrictions
|
|
|
934 prevent ordinary users from writing the lock files in /usr/spool/mail,
|
|
|
935 you may need to make `movemail' setgid to a suitable group such as
|
|
|
936 `mail'. To do this, use the following commands (as root) after doing
|
|
|
937 the make install.
|
|
|
938
|
|
|
939 chgrp mail movemail
|
|
|
940 chmod 2755 movemail
|
|
|
941
|
|
|
942 Installation normally copies movemail from the build directory to an
|
|
|
943 installation directory which is usually under /usr/local/lib. The
|
|
|
944 installed copy of movemail is usually in the directory
|
|
|
945 /usr/local/lib/emacs/VERSION/TARGET. You must change the group and
|
|
|
946 mode of the installed copy; changing the group and mode of the build
|
|
|
947 directory copy is ineffective.

952 The fonts of the "bold" and "italic" faces are generated from the font

954 have the appropriate size and family. However, emacs can only be

955 clever in this way if you have specified the default font using the
|

|

973
|
|

974 Two causes have been seen for such problems.
|
|
|
975
|
|
|
976 1) On a system where getpagesize is not a system call, it is defined
|
|
|
977 as a macro. If the definition (in both unexec.c and malloc.c) is wrong,
|
|
|
978 it can cause problems like this. You might be able to find the correct
|
|
|
979 value in the man page for a.out (5).
|
|
|
980
|
|
|
981 2) Some systems allocate variables declared static among the
|
|
|
982 initialized variables. Emacs makes all initialized variables in most
|
|
|
983 of its files pure after dumping, but the variables declared static and
|
|
|
984 not initialized are not supposed to be pure. On these systems you
|
|
|
985 may need to add "#define static" to the m- or the s- file.

994 *** When emacs starts up, I get lots of warnings about unknown keysyms.
|
|
124
|
995
|
|
|
996 If you are running the prebuilt binaries, the Motif library expects to find
|
|
|
997 certain thing in the XKeysymDB file. This file is normally in /usr/lib/X11/
|
|
|
998 or in /usr/openwin/lib/. If you keep yours in a different place, set the
|
|
454
|
999 environment variable $XKEYSYMDB to point to it before starting emacs. If
|
|
|
1000 you still have the problem after doing that, perhaps your version of X is
|
|
2536
|
1001 too old. There is a copy of the MIT X11R6 XKeysymDB file in the emacs `etc'

1020 addition, if you're using twm, make sure you have not specified

1021 "NoTitleFocus" in your .tvtwmrc file. The very nature of this option

|
0
|
1037
|
|
|
1038 This means that Control-S/Control-Q (XON/XOFF) "flow control" is being
|
|
|
1039 used. C-s/C-q flow control is bad for Emacs editors because it takes
|
|
|
1040 away C-s and C-q as user commands. Since editors do not output long
|
|
|
1041 streams of text without user commands, there is no need for a
|
|
|
1042 user-issuable "stop output" command in an editor; therefore, a
|
|
|
1043 properly designed flow control mechanism would transmit all possible
|
|
|
1044 input characters without interference. Designing such a mechanism is
|
|
|
1045 easy, for a person with at least half a brain.
|
|
|
1046
|
|
|
1047 There are three possible reasons why flow control could be taking place:
|
|
|
1048
|
|
|
1049 1) Terminal has not been told to disable flow control
|
|
|
1050 2) Insufficient padding for the terminal in use
|
|
|
1051 3) Some sort of terminal concentrator or line switch is responsible
|
|
|
1052
|
|
|
1053 First of all, many terminals have a set-up mode which controls whether
|
|
|
1054 they generate XON/XOFF flow control characters. This must be set to
|
|
|
1055 "no XON/XOFF" in order for Emacs to work. Sometimes there is an
|
|
|
1056 escape sequence that the computer can send to turn flow control off
|
|
|
1057 and on. If so, perhaps the termcap `ti' string should turn flow
|
|
|
1058 control off, and the `te' string should turn it on.
|
|
|
1059
|
|
|
1060 Once the terminal has been told "no flow control", you may find it
|
|
|
1061 needs more padding. The amount of padding Emacs sends is controlled
|
|
|
1062 by the termcap entry for the terminal in use, and by the output baud
|
|
|
1063 rate as known by the kernel. The shell command `stty' will print
|
|
|
1064 your output baud rate; `stty' with suitable arguments will set it if
|
|
|
1065 it is wrong. Setting to a higher speed causes increased padding. If
|
|
|
1066 the results are wrong for the correct speed, there is probably a
|
|
|
1067 problem in the termcap entry. You must speak to a local Unix wizard
|
|
|
1068 to fix this. Perhaps you are just using the wrong terminal type.
|
|
|
1069
|
|
|
1070 For terminals that lack a "no flow control" mode, sometimes just
|
|
|
1071 giving lots of padding will prevent actual generation of flow control
|
|
|
1072 codes. You might as well try it.
|
|
|
1073
|
|
|
1074 If you are really unlucky, your terminal is connected to the computer
|
|
|
1075 through a concentrator which sends XON/XOFF flow control to the
|
|
|
1076 computer, or it insists on sending flow control itself no matter how
|
|
|
1077 much padding you give it. Unless you can figure out how to turn flow
|
|
|
1078 control off on this concentrator (again, refer to your local wizard),
|
|
|
1079 you are screwed! You should have the terminal or concentrator
|
|
|
1080 replaced with a properly designed one. In the mean time, some drastic
|
|
|
1081 measures can make Emacs semi-work.
|
|
|
1082
|
|
|
1083 You can make Emacs ignore C-s and C-q and let the operating system
|
|
|
1084 handle them. To do this on a per-session basis, just type M-x
|
|
|
1085 enable-flow-control RET. You will see a message that C-\ and C-^ are
|
|
|
1086 now translated to C-s and C-q. (Use the same command M-x
|
|
|
1087 enable-flow-control to turn *off* this special mode. It toggles flow
|
|
|
1088 control handling.)
|
|
|
1089
|
|
|
1090 If C-\ and C-^ are inconvenient for you (for example, if one of them
|
|
|
1091 is the escape character of your terminal concentrator), you can choose
|
|
|
1092 other characters by setting the variables flow-control-c-s-replacement
|
|
|
1093 and flow-control-c-q-replacement. But choose carefully, since all
|
|
|
1094 other control characters are already used by emacs.
|
|
|
1095
|
|
|
1096 IMPORTANT: if you type C-s by accident while flow control is enabled,
|
|
|
1097 Emacs output will freeze, and you will have to remember to type C-q in
|
|
|
1098 order to continue.
|
|
|
1099
|
|
|
1100 If you work in an environment where a majority of terminals of a
|
|
|
1101 certain type are flow control hobbled, you can use the function
|
|
|
1102 `enable-flow-control-on' to turn on this flow control avoidance scheme
|
|
|
1103 automatically. Here is an example:
|
|
|
1104
|
|
|
1105 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")
|
|
|
1106
|
|
|
1107 If this isn't quite correct (e.g. you have a mixture of flow-control hobbled
|
|
|
1108 and good vt200 terminals), you can still run enable-flow-control
|
|
|
1109 manually.
|
|
|
1110
|
|
|
1111 I have no intention of ever redesigning the Emacs command set for the
|
|
|
1112 assumption that terminals use C-s/C-q flow control. XON/XOFF flow
|
|
|
1113 control technique is a bad design, and terminals that need it are bad
|
|
|
1114 merchandise and should not be purchased. Now that X is becoming
|
|
|
1115 widespread, XON/XOFF seems to be on the way out. If you can get some
|
|
|
1116 use out of GNU Emacs on inferior terminals, more power to you, but I
|
|
|
1117 will not make Emacs worse for properly designed systems for the sake
|
|
|
1118 of inferior systems.

1120 *** Control-S and Control-Q commands are ignored completely.
|
|
0
|
1121
|
|
|
1122 For some reason, your system is using brain-damaged C-s/C-q flow
|
|
|
1123 control despite Emacs's attempts to turn it off. Perhaps your
|
|
|
1124 terminal is connected to the computer through a concentrator
|
|
|
1125 that wants to use flow control.
|
|
|
1126
|
|
|
1127 You should first try to tell the concentrator not to use flow control.
|
|
|
1128 If you succeed in this, try making the terminal work without
|
|
|
1129 flow control, as described in the preceding section.
|
|
|
1130
|
|
|
1131 If that line of approach is not successful, map some other characters
|
|
|
1132 into C-s and C-q using keyboard-translate-table. The example above
|
|
|
1133 shows how to do this with C-^ and C-\.

1138 Some versions of rlogin (and possibly telnet) do not pass flow
|
|
|
1139 control characters to the remote system to which they connect.
|
|
|
1140 On such systems, emacs on the remote system cannot disable flow
|
|
|
1141 control on the local system.
|
|
|
1142
|
|
|
1143 One way to cure this is to disable flow control on the local host
|
|
|
1144 (the one running rlogin, not the one running rlogind) using the
|
|
|
1145 stty command, before starting the rlogin process. On many systems,
|
|
120
|
1146 `stty start u stop u' will do this.
|
|
0
|
1147
|
|
|
1148 Some versions of tcsh will prevent even this from working. One way
|
|
|
1149 around this is to start another shell before starting rlogin, and
|
|
|
1150 issue the stty command to disable flow control from that shell.
|
|
|
1151
|
|
|
1152 If none of these methods work, the best solution is to type
|
|
120
|
1153 `M-x enable-flow-control' at the beginning of your emacs session, or
|
|
0
|
1154 if you expect the problem to continue, add a line such as the
|
|
|
1155 following to your .emacs (on the host running rlogind):
|
|
|
1156
|
|
|
1157 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")

|
|
197
|
1163
|
|
|
1164 XEmacs has fairly new TTY redisplay support (beginning from 19.12),
|
|
|
1165 which doesn't include some basic TTY optimizations -- like using
|
|
|
1166 scrolling regions to move around blocks of text. This is why
|
|
454
|
1167 redisplay on the traditional terminals, or over slow lines can be very
|
|
197
|
1168 slow.

1178

|
1179 The first step in tracking this down is to record what characters
|
|
|
1180 Emacs is sending to the terminal. Execute the Lisp expression
|
|
120
|
1181 (open-termscript "./emacs-script") to make Emacs write all terminal
|
|
|
1182 output into the file ~/emacs-script as well; then do what makes the
|
|
|
1183 screen update wrong, and look at the file and decode the characters
|
|
|
1184 using the manual for the terminal. There are several possibilities:
|
|
0
|
1185
|
|
|
1186 1) The characters sent are correct, according to the terminal manual.
|
|
|
1187
|
|
|
1188 In this case, there is no obvious bug in Emacs, and most likely you
|
|
|
1189 need more padding, or possibly the terminal manual is wrong.
|
|
|
1190
|
|
120
|
1191 2) The characters sent are incorrect, due to an obscure aspect of the
|
|
|
1192 terminal behavior not described in an obvious way by termcap.
|
|
0
|
1193
|
|
120
|
1194 This case is hard. It will be necessary to think of a way for Emacs
|
|
|
1195 to distinguish between terminals with this kind of behavior and other
|
|
|
1196 terminals that behave subtly differently but are classified the same
|
|
|
1197 by termcap; or else find an algorithm for Emacs to use that avoids the
|
|
|
1198 difference. Such changes must be tested on many kinds of terminals.

1219
|

1220 twm normally ignores "program-specified" positions.
|
|
|
1221 You can tell it to obey them with this command in your `.twmrc' file:

1227

|
|
1228 This has been traced to communicating with your machine via kermit,
|
|
|
1229 with C-\ as the kermit escape character. One solution is to use
|
|
|
1230 another escape character in kermit. One user did

|
1232 set escape-character 17

1236 *** The Motif version of Emacs paints the screen a solid color.

1240 Emacs*default.attributeFont: -*-courier-medium-r-*-*-*-140-*-*-*-*-iso8859-*
|
|
|
1241
|
|
|
1242 That the resource has this effect indicates a bug in something, but we
|
|
|
1243 do not yet know what. If it is an Emacs bug, we hope someone can
|
|
|
1244 explain what the bug is so we can fix it. In the mean time, removing
|
|
|
1245 the resource prevents the problem.

|
|
1247 *** After running emacs once, subsequent invocations crash.
|
|
|
1248
|
|
|
1249 Some versions of SVR4 have a serious bug in the implementation of the
|
|
|
1250 mmap () system call in the kernel; this causes emacs to run correctly
|
|
|
1251 the first time, and then crash when run a second time.
|
|
|
1252
|
|
|
1253 Contact your vendor and ask for the mmap bug fix; in the mean time,
|
|
|
1254 you may be able to work around the problem by adding a line to your
|
|
|
1255 operating system description file (whose name is reported by the
|
|
|
1256 configure script) that reads:
|
|
|
1257 #define SYSTEM_MALLOC
|
|
|
1258 This makes Emacs use memory less efficiently, but seems to work around
|
|
|
1259 the kernel bug.

|
1261 *** Inability to send an Alt-modified key, when Emacs is communicating
|
|
|
1262 directly with an X server.
|
|
|
1263
|
|
|
1264 If you have tried to bind an Alt-modified key as a command, and it
|
|
|
1265 does not work to type the command, the first thing you should check is
|
|
|
1266 whether the key is getting through to Emacs. To do this, type C-h c
|
|
|
1267 followed by the Alt-modified key. C-h c should say what kind of event
|
|
|
1268 it read. If it says it read an Alt-modified key, then make sure you
|
|
|
1269 have made the key binding correctly.
|
|
|
1270
|
|
|
1271 If C-h c reports an event that doesn't have the Alt modifier, it may
|
|
|
1272 be because your X server has no key for the Alt modifier. The X
|
|
|
1273 server that comes from MIT does not set up the Alt modifier by
|
|
|
1274 default.
|
|
|
1275
|
|
|
1276 If your keyboard has keys named Alt, you can enable them as follows:
|
|
|
1277
|
|
|
1278 xmodmap -e 'add mod2 = Alt_L'
|
|
|
1279 xmodmap -e 'add mod2 = Alt_R'
|
|
|
1280
|
|
|
1281 If the keyboard has just one key named Alt, then only one of those
|
|
|
1282 commands is needed. The modifier `mod2' is a reasonable choice if you
|
|
|
1283 are using an unmodified MIT version of X. Otherwise, choose any
|
|
|
1284 modifier bit not otherwise used.
|
|
|
1285
|
|
|
1286 If your keyboard does not have keys named Alt, you can use some other
|
|
|
1287 keys. Use the keysym command in xmodmap to turn a function key (or
|
|
|
1288 some other 'spare' key) into Alt_L or into Alt_R, and then use the
|
|
|
1289 commands show above to make them modifier keys.
|
|
|
1290
|
|
|
1291 Note that if you have Alt keys but no Meta keys, Emacs translates Alt
|
|
|
1292 into Meta. This is because of the great importance of Meta in Emacs.
|
|
|
1293
|
|
|
1294 *** In Shell mode, you get a ^M at the end of every line.
|
|
|
1295
|
|
|
1296 This happens to people who use tcsh, because it is trying to be too
|
|
|
1297 smart. It sees that the Shell uses terminal type `unknown' and turns
|
|
|
1298 on the flag to output ^M at the end of each line. You can fix the
|
|
|
1299 problem by adding this to your .cshrc file:
|
|
|
1300
|
|
|
1301 if ($?EMACS) then
|
|
|
1302 if ($EMACS == "t") then
|

1311 This comes from having an invalid X resource, such as
|
|
|
1312 emacs*Cursor: black
|
|
|
1313 (which is invalid because it specifies a color name for something

1318 *** Once you pull down a menu from the menubar, it won't go away.
|
|
|
1319
|
|
|
1320 It has been claimed that this is caused by a bug in certain very old
|
|
|
1321 (1990?) versions of the twm window manager. It doesn't happen with
|
|
|
1322 recent vintages, or with other window managers.

1324 *** Emacs ignores the "help" key when running OLWM.
|
|
|
1325
|
|
|
1326 OLWM grabs the help key, and retransmits it to the appropriate client
|
|
|
1327 using XSendEvent. Allowing emacs to react to synthetic events is a
|
|
|
1328 security hole, so this is turned off by default. You can enable it by
|
|
|
1329 setting the variable x-allow-sendevents to t. You can also cause fix
|
|
|
1330 this by telling OLWM to not grab the help key, with the null binding
|
|
|
1331 "OpenWindows.KeyboardCommand.Help:".

1333 *** Programs running under terminal emulator do not recognize `emacs'
|
|
|
1334 terminal type.
|
|
|
1335
|
|
|
1336 The cause of this is a shell startup file that sets the TERMCAP
|
|
|
1337 environment variable. The terminal emulator uses that variable to
|
|
|
1338 provide the information on the special terminal type that Emacs
|
|
|
1339 emulates.
|
|
|
1340
|
|
|
1341 Rewrite your shell startup file so that it does not change TERMCAP
|
|
|
1342 in such a case. You could use the following conditional which sets
|
|
|
1343 it only if it is undefined.
|
|
|
1344
|
|
|
1345 if ( ! ${?TERMCAP} ) setenv TERMCAP ~/my-termcap-file
|
|
|
1346
|
|
|
1347 Or you could set TERMCAP only when you set TERM--which should not
|
|
|
1348 happen in a non-login shell.

|
|
|
1361 undefined symbols.
|
|
|
1362
|
|
|
1363 The only known case in which this happens is if you are using gcc, you
|
|
|
1364 configured with --error-checking=all and --with-modules, and you
|
|
|
1365 compiled with no optimization. If you encounter this problem in any
|
|
|
1366 other situation, please inform xemacs-beta@xemacs.org.
|
|
|
1367
|
|
|
1368 This problem stems from a gcc bug. With no optimization, functions
|
|
|
1369 declared `extern inline' sometimes are not completely compiled away. An
|
|
|
1370 undefined symbol with the function's name is put into the resulting
|
|
|
1371 object file. In this case, when the postgresql module is loaded, the
|
|
|
1372 linker is unable to resolve that symbol, so the module load fails. The
|
|
|
1373 workaround is to recompile the module with optimization turned on. Any
|
|
|
1374 optimization level, including -Os, appears to work.

1384 with large compilation buffers, or in other regex applications.

1385
|
|
|
1386 The default stack size under MacOS/X is rather small (512k as opposed
|
|

1387 to Solaris 8M), hosing the regexp code, which uses alloca()
|
|
|
1388 extensively, overflowing the stack when complex regexps are used.
|
|
|
1389 Workarounds:
|
|
|
1390
|
|
|
1391 1) Increase your stack size, using `ulimit -s 8192' or a (t)csh
|
|
|
1392 equivalent;
|
|
|
1393
|
|
|
1394 2) Recompile regex.c with REGEX_MALLOC defined.

1452 include files. In particular, on Suns, the file

|
1453 /usr/include/sun/audioio.h uses the _IOW macro to define the constant
|
|
|
1454 AUDIOSETQSIZE. _IOW in turn uses a K&R preprocessor feature that is
|
|
|
1455 now explicitly forbidden in ANSI preprocessors, namely substitution
|
|
|
1456 inside character constants. All ANSI C compilers must provide a
|

1457 workaround for this problem. Lucid's C compiler is shipped with a new

|
1521 This happens if you configure Emacs specifying just `sparc-sun-sunos4'
|
|
|
1522 on a system that is version 4.1.3. You must specify the precise
|
|
|
1523 version number (or let configure figure out the configuration, which
|
|
|
1524 it can do perfectly well for SunOS).

1526 *** Mail is lost when sent to local aliases.
|

0
|
1527
|
|
124
|
1528 Many emacs mail user agents (VM and rmail, for instance) use the
|
|
|
1529 sendmail.el library. This library can arrange for mail to be
|
|
|
1530 delivered by passing messages to the /usr/lib/sendmail (usually)
|
|
|
1531 program . In doing so, it passes the '-t' flag to sendmail, which
|
|
|
1532 means that the name of the recipient of the message is not on the
|
|
|
1533 command line and, therefore, that sendmail must parse the message to
|
|
|
1534 obtain the destination address.
|
|
|
1535
|
|
|
1536 There is a bug in the SunOS4.1.1 and SunOS4.1.3 versions of sendmail.
|
|
|
1537 In short, when given the -t flag, the SunOS sendmail won't recognize
|
|
|
1538 non-local (i.e. NIS) aliases. It has been reported that the Solaris
|
|
|
1539 2.x versions of sendmail do not have this bug. For those using SunOS
|
|
|
1540 4.1, the best fix is to install sendmail V8 or IDA sendmail (which
|
|
|
1541 have other advantages over the regular sendmail as well). At the time
|
|
|
1542 of this writing, these official versions are available:
|
|
|
1543
|
|
|
1544 Sendmail V8 on ftp.cs.berkeley.edu in /ucb/sendmail:
|
|
|
1545 sendmail.8.6.9.base.tar.Z (the base system source & documentation)
|
|
|
1546 sendmail.8.6.9.cf.tar.Z (configuration files)

|
1557
|
|
124
|
1558 This typically happens on Suns and other systems that use shared
|
|
|
1559 libraries. The cause is that the site has installed a version of the
|
|
|
1560 shared library which uses a name server--but has not installed a
|
|
|
1561 similar version of the unshared library which Emacs uses.
|
|
0
|
1562
|
|
124
|
1563 The result is that most programs, using the shared library, work with
|
|
|
1564 the nameserver, but Emacs does not.
|
|
|
1565
|
|
|
1566 The fix is to install an unshared library that corresponds to what you
|
|
|
1567 installed in the shared library, and then relink Emacs.

1568

1569 On SunOS 4.1, simply define HAVE_RES_INIT.
|
|
|
1570
|
|
|
1571 If you have already installed the name resolver in the file libresolv.a,
|
|
|
1572 then you need to compile Emacs to use that library. The easiest way to
|
|
|
1573 do this is to add to config.h a definition of LIBS_SYSTEM, LIBS_MACHINE
|
|
|
1574 or LIB_STANDARD which uses -lresolv. Watch out! If you redefine a macro
|
|
|
1575 that is already in use in your configuration to supply some other libraries,
|
|
|
1576 be careful not to lose the others.
|
|
|
1577
|
|
|
1578 Thus, you could start by adding this to config.h:
|
|
|
1579
|
|
|
1580 #define LIBS_SYSTEM -lresolv
|
|
|
1581
|
|
|
1582 Then if this gives you an error for redefining a macro, and you see that
|
|
|
1583 the s- file defines LIBS_SYSTEM as -lfoo -lbar, you could change config.h
|
|
|
1584 again to say this:
|
|
|
1585
|
|
|
1586 #define LIBS_SYSTEM -lresolv -lfoo -lbar

|
|
|
1590
|
|
|
1591 On SunOS systems, this problem has been seen to be a result of an
|
|
|
1592 incomplete installation of gcc 2.2 which allowed some non-ANSI
|
|
|
1593 compatible include files into the compilation. In particular this
|
|
|
1594 affected virtually all ioctl() calls.

1598 *** XEmacs crashes on startup, in make-frame.
|
|
|
1599
|
|
|
1600 Typically the Lisp backtrace includes
|
|
|
1601
|
|
|
1602 make-frame(nil #<x-device on ":0.0" 0x2558>)
|
|
|
1603
|
|
|
1604 somewhere near the top. The problem is due to an improvement in GNU
|
|
|
1605 ld that sorts the ELF reloc sections in the executable, giving
|
|
|
1606 dramatic speedups in startup for large executables. It also confuses
|
|
|
1607 the traditional unexec code in XEmacs, leading to the core dump. The
|
|
|
1608 solution is to use the --pdump or --ldflags='-z nocombreloc' options
|
|
|
1609 to configure. Recent 21.4 and 12.5 autodetect this in configure.
|
|
|
1610
|
|
|
1611 Red Hat and SuSE (at least) distributed a prerelease version of ld
|
|
|
1612 (versions around 2.11.90.x.y) where autodetection is impossible. The
|
|
|
1613 recommended procedure is to upgrade to binutils >= 2.12 and rerun
|
|
|
1614 configure. Otherwise you must apply the flags by hand. --pdump is
|
|
|
1615 recommended.

1617 *** I want XEmacs to use the Alt key, not the XXX key, for Meta commands
|
|
|
1618
|
|
|
1619 For historical reasons, XEmacs looks for a Meta key, then an Alt key.
|
|
|
1620 It binds Meta commands to the X11 modifier bit attached to the first
|
|
|
1621 of these it finds. On PCs, the Windows key is often assigned the Meta
|
|
|
1622 bit, but many desktop environments go to great lengths to get all apps
|
|
|
1623 to use the Alt key, and reserve the Windows key to (sensibly enough)
|
|
|
1624 the window manager.
|
|
|
1625
|
|
|
1626 One correct way to implement this was suggested on comp.emacs.xemacs
|
|
|
1627 (by Kilian Foth and in more detail by Michael Piotrowski): unmap the
|
|
|
1628 Meta modifier using xmodmap or xkb, and then map the Meta/Windows key
|
|
450
|
1629 to the Super or Hyper keysym and an appropriate mod bit. XEmacs will
|
|
|
1630 not find the Meta keysym, and default to using the Alt key for Meta
|
|
|
1631 keybindings. Typically few applications use the (X11) Meta modifier;
|
|
|
1632 it is tedious but not too much so to teach the ones you need to use
|
|
|
1633 Super instead of Meta. There may be further useful hints in the
|
|
|
1634 discussion of keymapping on non-Linux platforms.

|
|
|
1636 *** The color-gcc wrapper
|
|
|
1637
|
|
|
1638 This wrapper colorizes the error messages from gcc. By default XEmacs
|
|
|
1639 does not interpret the escape sequences used to generate colors,
|
|
|
1640 resulting in a cluttered, hard-to-read buffer. You can remove the
|
|
|
1641 wrapper, or defeat the wrapper colorization in Emacs process buffers
|
|
|
1642 by editing the "nocolor" attribute in /etc/colorgccrc:
|
|
|
1643
|
|
|
1644 $ diff -u /etc/colorgccrc.old /etc/colorgccrc

|
1659 *** Slow startup on Linux.
|
|
|
1660
|
|
|
1661 People using systems based on the Linux kernel sometimes report that
|
|
448
|
1662 startup takes 10 to 15 seconds longer than `usual'. There are two
|
|
|
1663 problems, one older, one newer.
|
|
|
1664
|
|
|
1665 **** Old problem: IPv4 host lookup
|
|
373
|
1666
|
|
448
|
1667 On older systems, this is because Emacs looks up the host name when it
|
|
|
1668 starts. Normally, this takes negligible time; the extra delay is due
|
|
|
1669 to improper system configuration. (Recent Linux distros usually have
|
|
|
1670 this configuration correct "out of the box".) This problem can occur
|
|
|
1671 for both networked and non-networked machines.
|
|
373
|
1672
|
|
|
1673 Here is how to fix the configuration. It requires being root.
|
|
|
1674
|
|
448
|
1675 ***** Networked Case
|
|
373
|
1676
|
|
|
1677 First, make sure the files `/etc/hosts' and `/etc/host.conf' both
|
|
|
1678 exist. The first line in the `/etc/hosts' file should look like this
|
|
|
1679 (replace HOSTNAME with your host name):
|
|
|
1680
|
|
|
1681 127.0.0.1 localhost HOSTNAME
|
|
|
1682
|
|
|
1683 Also make sure that the `/etc/host.conf' files contains the following
|
|
|
1684 lines:
|
|
|
1685
|
|
454
|
1686 order hosts, bind
|
|
373
|
1687 multi on
|
|
|
1688
|
|
|
1689 Any changes, permanent and temporary, to the host name should be
|
|
|
1690 indicated in the `/etc/hosts' file, since it acts a limited local
|
|
|
1691 database of addresses and names (e.g., some SLIP connections
|
|
|
1692 dynamically allocate ip addresses).
|
|
|
1693
|
|
448
|
1694 ***** Non-Networked Case
|
|
373
|
1695
|
|
|
1696 The solution described in the networked case applies here as well.
|
|
|
1697 However, if you never intend to network your machine, you can use a
|
|
|
1698 simpler solution: create an empty `/etc/host.conf' file. The command
|
|
|
1699 `touch /etc/host.conf' suffices to create the file. The `/etc/hosts'
|
|
|
1700 file is not necessary with this approach.
|
|
|
1701
|
|
448
|
1702 **** New problem: IPv6 CNAME lookup
|
|
|
1703
|
|
|
1704 A newer problem is due to XEmacs changing to use the modern
|
|
|
1705 getaddrinfo() interface from the older gethostbyname() interface. The
|
|
|
1706 solution above is insufficient, because getaddrinfo() by default tries
|
|
|
1707 to get IPv6 information for localhost. This always involves a dns
|
|
|
1708 lookup to get the CNAME, and the strategies above don't work. It then
|
|
724
|
1709 falls back to IPv4 behavior. This is good[tm] according the people at
|
|
|
1710 WIDE who know about IPv6.
|
|
448
|
1711
|
|
|
1712 ***** Robust network case
|
|
|
1713
|
|
|
1714 Configure your network so that there are no nameservers configured
|
|
|
1715 until the network is actually running. getaddrinfo() will not try to
|
|
|
1716 access a nameserver that isn't configured.
|
|
|
1717
|
|
|
1718 ***** Flaky network case
|
|
|
1719
|
|
|
1720 If you have a flaky modem or DSL connection that can be relied on only
|
|
|
1721 to go down whenever you want to bring XEmacs up, you need to force
|
|
|
1722 IPv4 behavior. Explicitly setting DISPLAY=127.0.0.1:0.0 (or whatever
|
|
|
1723 is appropriate) works in most cases.
|
|
|
1724
|
|
|
1725 If you cannot or do not want to do that, you can hard code IPv4
|
|
|
1726 behavior in src/process-unix.c. This is bad[tm], on your own head be
|
|
724
|
1727 it. Use the configure option `--with-ipv6-cname=no'.
|
|
373
|
1728
|
|
845
|
1729 *** Mandrake
|
|
|
1730
|
|
|
1731 The Mandrake Linux distribution is attempting to comprehensively
|
|
|
1732 update the user interface, and make it consistent across
|
|
|
1733 applications. This is very difficult, and will occasionally cause
|
|
|
1734 conflicts with applications like Emacs with their own long-established
|
|
|
1735 interfaces. Known issues specific to Mandrake or especially common:
|
|
|
1736
|
|
|
1737 Some versions of XEmacs (21.1.9 is known) distributed with Mandrake
|
|
|
1738 were patched to make the Meta and Alt keysyms synonymous. These
|
|
|
1739 normally work as expected in the Mandrake environment. However,
|
|
|
1740 custom-built XEmacsen (including all 21.2 betas) will "inexplicably"
|
|
|
1741 not respect the "Alt-invokes-Meta-commands" convention. See "I want
|
|
|
1742 XEmacs to use the Alt key" below.
|
|
|
1743
|
|
|
1744 The color-gcc wrapper (see below) is in common use on the Mandrake
|
|
|
1745 platform.
|
|
|
1746
|
|
|
1747 *** You get crashes in a non-C locale with Linux GNU Libc 2.0.
|
|
|
1748
|
|
|
1749 Internationalization was not the top priority for GNU Libc 2.0.
|
|
|
1750 As of this writing (1998-12-28) you may get crashes while running
|
|
|
1751 XEmacs in a non-C locale. For example, `LC_ALL=en_US xemacs' crashes
|
|
|
1752 while `LC_ALL=C xemacs' runs fine. This happens for example with GNU
|
|
|
1753 libc 2.0.7. Installing libintl.a and libintl.h built from gettext
|
|
|
1754 0.10.35 and re-building XEmacs solves the crashes. Presumably soon
|
|
|
1755 everyone will upgrade to GNU Libc 2.1 and this problem will go away.
|
|
|
1756
|
|
|
1757 *** `C-z', or `M-x suspend-emacs' hangs instead of suspending.
|
|
|
1758
|
|
|
1759 If you build with `gpm' support on Linux, you cannot suspend XEmacs
|
|
|
1760 because gpm installs a buggy SIGTSTP handler. Either compile with
|
|
|
1761 `--with-gpm=no', or don't suspend XEmacs on the Linux console until
|
|
|
1762 this bug is fixed.

1764 *** With certain fonts, when the cursor appears on a character, the
|
|
|
1765 character doesn't appear--you get a solid box instead.
|
|
|
1766
|
|
|
1767 One user on a Linux system reported that this problem went away with
|
|
|
1768 installation of a new X server. The failing server was XFree86 3.1.1.
|
|
|
1769 XFree86 3.1.2 works.

|

|

1774
|
|
|
1775 SGI ships a really old Xpm library in /usr/lib which does not work at
|
|
|
1776 all well with XEmacs. The solution is to install your own copy of the
|
|
|
1777 latest version of Xpm somewhere and then use the --site-includes and
|
|
|
1778 --site-libraries flags to tell configure where to find it.
|
|
|
1779
|
|
|
1780 *** Trouble using ptys on IRIX, or running out of ptys.
|
|
|
1781
|
|
|
1782 The program mkpts (which may be in `/usr/adm' or `/usr/sbin') needs to
|
|
|
1783 be set-UID to root, or non-root programs like Emacs will not be able
|
|
|
1784 to allocate ptys reliably.

373
|
1797
|

1798 The default stack size under Digital Unix is rather small (2M as

1801 Workarounds:

373
|
1803 1) Increase your stack size, using `ulimit -s 8192' or a (t)csh

1810 The default DEC keyboard mapping has the Alt keys set up to generate the

1811 keysym `Multi_key', which has a meaning to xemacs which is distinct from that
|
|
|
1812 of the `Meta_L' and `Meta-R' keysyms. A second problem is that certain keys
|
|
|
1813 have the Mod2 modifier attached to them for no adequately explored reason.
|
|
|
1814 The correct fix is to pass this file to xmodmap upon starting X:

1816 clear mod2

1817 keysym Multi_key = Alt_L

1849 Meta_L and Mode_switch (even though there is not actually a Mode_switch key on

|
1850 the keyboard -- it uses an "imaginary" keycode.) There actually is a reason

|
|
1851 for this, but it's not a good one. The correct fix is to execute this command
|

1852 upon starting X:

1899 *** XEmacs dumps core at startup when native audio is used. Native
|
|
|
1900 audio does not work with recent versions of HP-UX.
|
|
|
1901
|
|
|
1902 Under HP-UX 10.20 and later (e.g., HP-UX 11.XX), with native audio
|
|
|
1903 enabled, the dumped XEmacs binary ("xemacs") core dumps at startup if
|
|
|
1904 recent versions of the libAlib.sl audio shared library is used. Note
|
|
|
1905 that "temacs" will run, but "xemacs" will dump core. This, of course,
|
|
|
1906 causes the XEmacs build to fail. If GNU malloc is enabled, a stack
|
|
|
1907 trace will show XEmacs to have crashed in the "first" call to malloc().
|
|
|
1908
|
|
|
1909 This bug currently exists in all versions of XEmacs, when the undump
|
|
|
1910 mechanism is used. It is not known if using the experimental portable
|
|
|
1911 dumper will allow native audio to work.
|
|
|
1912
|
|
|
1913 **** Cause:
|
|
|
1914
|
|
|
1915 Recent versions of the HP-UX 10.20 (and later) audio shared library (in
|
|
|
1916 /opt/audio/lib), pulls in the libdce shared library, which pulls in a
|
|
|
1917 thread (libcma) library. This prevents the HP-UX undump() routine (in
|
|
|
1918 unexhp9k800.c) from properly working. What's happening is that some
|
|
|
1919 initialization routines are being called in the libcma library, *BEFORE*
|
|
|
1920 main() is called, and these initialization routines are calling
|
|
|
1921 malloc(). Unfortunately, in order for the undumper to work, XEmacs must
|
|
|
1922 adjust (move upwards) the sbrk() value *BEFORE* the first call to
|
|
|
1923 malloc(); if malloc() is called before XEmacs has properly adjusted sbrk
|
|
|
1924 (which is what is happening), dumped memory that is being used by
|
|
|
1925 XEmacs, is improperly re-allocated for use by malloc() and the dumped
|
|
|
1926 memory is corrupted. This causes XEmacs to die an horrible death.
|
|
|
1927
|
|
|
1928 It is believed that versions of the audio library past December 1998
|
|
|
1929 will trigger this problem. Under HP-UX 10.20, you probably have to
|
|
|
1930 install audio library patches to encounter this. It's probable that
|
|
|
1931 recent "fresh, out-of-the-box" HP-UX 11.XX workstations also have this
|
|
|
1932 problem. For HP-UX 10.20, it's believed that audio patch PHSS_17121 (or
|
|
|
1933 a superceeding one, like PHSS_17554, PHSS_17971, PHSS_18777, PHSS_21481,
|
|
|
1934 or PHSS_21662, etc.) will trigger this.
|
|
|
1935
|
|
|
1936 To check if your audio library will cause problems for XEmacs, run
|
|
|
1937 "chatr /opt/audio/lib/libAlib.sl". If "libdce" appears in the displayed
|
|
|
1938 shared library list, XEmacs will probably encounter problems if audio is
|
|
|
1939 enabled.
|
|
|
1940
|
|
|
1941 **** Workaround:
|
|
|
1942
|
|
|
1943 Don't enable native audio. Re-run configure without native audio
|
|
|
1944 support.
|
|
|
1945
|
|
|
1946 If your site supports it, try using NAS (Network Audio Support).
|
|
|
1947
|
|
|
1948 Try using the experimental portable dumper. It may work, or it may
|
|
|
1949 not.

1952 *** `Pid xxx killed due to text modification or page I/O error'

1953
|
|
|
1954 On HP-UX, you can get that error when the Emacs executable is on an NFS
|
|
|
1955 file system. HP-UX responds this way if it tries to swap in a page and
|
|
|
1956 does not get a response from the server within a timeout whose default
|
|
|
1957 value is just ten seconds.

1964
|

|
1965 The problem is that in your .cshrc you have something that tries to
|
|
197
|
1966 execute `tty`. If you are not running the shell on a real tty then tty
|
|
|
1967 will print "not a tty". Csh expects one word in some places, but tty
|
|
|
1968 is giving it back 3.
|
|
124
|
1969
|
|
197
|
1970 The solution is to add a pair of quotes around `tty` to make it a
|
|
|
1971 single word:
|

0

1972

454

1973 if (`tty` == "/dev/console")

|
|
|
1995
|
|

1996 Depending on how it is installed, FSF NTEmacs may setup various EMACS*
|
|
|
1997 variables in your environment. The presence of these variables may
|
|
|
1998 cause XEmacs to fail at startup, cause you to see corrupted
|
|
|
1999 doc-strings, or cause other random problems.
|
|
|
2000
|
|
|
2001 You should remove these variables from your environment. These
|
|
|
2002 variables are not required to run FSF NTEmacs if you start it by
|
|
|
2003 running emacs.bat.

|
|
|
2005 *** XEmacs can't find my init file
|
|
|
2006
|
|
|
2007 XEmacs looks for your init in your "home" directory -- either in
|
|
|
2008 `~/.xemacs/init.el' or `~/.emacs'. XEmacs decides that your "home"
|
|
|
2009 directory is, in order of preference:
|
|
|
2010
|
|
|
2011 - The value of the HOME environment variable, if the variable exists.
|
|
|
2012 - The value of the registry entry SOFTWARE\XEmacs\XEmacs\HOME,
|
|
|
2013 if it exists.
|
|
|
2014 - The value of the HOMEDRIVE and HOMEPATH environment variables, if
|
|
|
2015 these variables both exist.
|
|
|
2016 - C:\.
|
|
|
2017
|
|
|
2018 To determine what XEmacs thinks your home directory is, try opening
|
|
|
2019 a file in the `~' directory, and you should see its expansion in the
|
|
|
2020 modeline. If this doesn't work, type ESC : (user-home-directory).
|
|
|
2021
|
|
|
2022 *** XEmacs can't find any packages
|
|
|
2023
|
|
|
2024 XEmacs looks for your packages in subdirectories of a directory which
|
|
|
2025 is set at compile-time (see `config.inc'), and whose default is
|
|
|
2026 `C:\Program Files\XEmacs'. XEmacs also looks in `~/.xemacs', where
|
|
|
2027 `~' refers to your home directory (see previous entry). The variable
|
|
|
2028 `configure-package-path' holds the actual path that was compiled into
|
|
|
2029 your copy of XEmacs.
|
|
|
2030
|
|
|
2031 The compile-time default location can be overridden by the EMACSPACKAGEPATH
|
|
|
2032 environment variable or by the SOFTWARE\XEmacs\XEmacs\EMACSPACKAGEPATH
|
|
|
2033 registry entry. You should check that these variables, if they exist,
|
|
|
2034 point to the actual location of your package tree.

|

|
|
|
2040 It is safe to
|
|
|
2041 "Click OK to quit the program and Windows",
|
|
|
2042 but you won't be offered a chance to save any modified XEmacs buffers.

|
2044 *** Key bindings
|
|
|
2045
|
|
|
2046 The C-z, C-x, C-c, and C-v keystrokes have traditional uses in both
|
|
|
2047 emacs and Windows programs. XEmacs binds these keys to their
|
|
|
2048 traditional emacs uses, and provides Windows 3.x style bindings for
|
|
|
2049 the Cut, Copy and Paste functions.

|
|

2057
|

2058 You can rebind keys to make XEmacs more Windows-compatible; for
|
|
|
2059 example, to bind C-z to undo:
|
|
|
2060
|
|
|
2061 (global-set-key [(control z)] 'undo)
|
|
|
2062
|
|
|
2063 Rebindind C-x and C-c is trickier because by default these are prefix
|
|
|
2064 keys in XEmacs. See the "Key Bindings" node in the XEmacs manual.

2071 *** Limitations on the use of the AltGr key.
|
|
|
2072
|
|
|
2073 In some locale and OS combinations you can't generate M-AltGr-key or
|
|
|
2074 C-M-AltGr-key sequences at all.
|
|
|
2075
|
|
|
2076 To generate C-AltGr-key or C-M-AltGr-key sequences you must use the
|
|
|
2077 right-hand Control key and you must press it *after* AltGr.
|
|
|
2078
|
|
|
2079 These limitations arise from fundamental problems in the way that the
|
|
|
2080 win32 API reports AltGr key events. There isn't anything that XEmacs
|
|
|
2081 can do to work round these problems that it isn't already doing.
|
|
|
2082
|
|
|
2083 You may want to create alternative bindings if any of the standard
|
|
|
2084 XEmacs bindings require you to use some combination of Control or Meta
|
|
|
2085 and AltGr.

2087 *** Limited support for subprocesses under Windows 9x
|
|
|
2088
|
|
|
2089 Attempting to use call-process to run a 16bit program gives a
|
|
|
2090 "Spawning child process: Exec format error". For example shell-command
|
|
|
2091 fails under Windows 95 and 98 if you use command.com or any other
|
|
|
2092 16bit program as your shell.
|
|
|
2093
|
|
|
2094 XEmacs may incorrectly quote your call-process command if it contains
|
|
|
2095 double quotes, backslashes or spaces.
|
|
|
2096
|
|
|
2097 start-process and functions that rely on it are supported under Windows 95,
|
|
|
2098 98 and NT. However, starting a 16bit program that requires keyboard input
|
|
|
2099 may cause XEmacs to hang or crash under Windows 95 and 98, and will leave
|
|
|
2100 the orphaned 16bit program consuming all available CPU time.
|
|
|
2101
|
|
|
2102 Sending signals to subprocesses started by call-process or by
|
|
|
2103 start-process fails with a "Cannot send signal to process" error under
|
|
|
2104 Windows 95 and 98. As a side effect of this, quitting XEmacs while it
|
|
|
2105 is still running subprocesses causes it to crash under Windows 95 and
|

|
2106 98.

2147 * Compatibility problems (with Emacs 18, GNU Emacs, or previous XEmacs/lemacs)
|
|
197
|
2148 ==============================================================================
|
|

|
2149
|
|

|
2150 *** "Symbol's value as variable is void: unread-command-char".
|
|
197
|
2151 "Wrong type argument: arrayp, #<keymap 143 entries>"
|
|
|
2152 "Wrong type argument: stringp, [#<keypress-event return>]"
|
|
88
|
2153
|
|
124
|
2154 There are a few incompatible changes in XEmacs, and these are the
|
|
|
2155 symptoms. Some of the emacs-lisp code you are running needs to be
|
|
|
2156 updated to be compatible with XEmacs.
|
|
|
2157
|
|
|
2158 The code should not treat keymaps as arrays (use `define-key', etc.),
|
|
|
2159 should not use obsolete variables like `unread-command-char' (use
|
|
197
|
2160 `unread-command-events'). Many (most) of the new ways of doing things
|
|
124
|
2161 are compatible in GNU Emacs and XEmacs.
|
|
88
|
2162
|
|
197
|
2163 Modern Emacs packages (Gnus, VM, W3, efs, etc) are written to support
|
|
|
2164 GNU Emacs and XEmacs. We have provided modified versions of several
|
|
|
2165 popular emacs packages (dired, etc) which are compatible with this
|
|
|
2166 version of emacs. Check to make sure you have not set your load-path
|
|
|
2167 so that your private copies of these packages are being found before
|
|
|
2168 the versions in the lisp directory.
|
|
124
|
2169
|
|
|
2170 Make sure that your load-path and your $EMACSLOADPATH environment
|
|
|
2171 variable are not pointing at an Emacs18 lisp directory. This will
|
|
|
2172 cripple emacs.
|
|

|
2173
|
|
124
|
2174 ** Some packages that worked before now cause the error
|
|
223
|
2175 Wrong type argument: arrayp, #<face ... >
|
|
124
|
2176
|
|
197
|
2177 Code which uses the `face' accessor functions must be recompiled with
|
|
|
2178 xemacs 19.9 or later. The functions whose callers must be recompiled
|
|
|
2179 are: face-font, face-foreground, face-background,
|
|
|
2180 face-background-pixmap, and face-underline-p. The .elc files
|
|
|
2181 generated by version 19.9 will work in 19.6 and 19.8, but older .elc
|
|
|
2182 files which contain calls to these functions will not work in 19.9.
|
|

|
2183
|
|
|
2184 ** Signaling: (error "Byte code stack underflow (byte compiler bug), pc 38")
|
|
88
|
2185
|
|
120
|
2186 This error is given when XEmacs 20 is compiled without MULE support
|
|
88
|
2187 but is attempting to load a .elc which requires MULE support. The fix
|
|
|
2188 is to rebytecompile the offending file.

2190 ** Signaling: (wrong-type-argument ...) when loading mail-abbrevs

197
|
2192 The is seen when installing the Insidious Big Brother Data Base (bbdb)
|
|
|
2193 which includes an outdated copy of mail-abbrevs.el. Remove the copy
|
|
|
2194 that comes with bbdb and use the one that comes with XEmacs.

2197 * MULE issues
|
|
197
|
2198 =============
|
|
144
|
2199
|
|
223
|
2200 ** A reminder: XEmacs/Mule work does not currently receive *any*
|
|
|
2201 funding, and all work is done by volunteers. If you think you can
|
|
|
2202 help, please contact the XEmacs maintainers.
|
|
|
2203
|
|
278
|
2204 ** XEmacs/Mule doesn't support TTY's satisfactorily.
|
|
223
|
2205
|
|
|
2206 This is a major problem, which we plan to address in a future release
|
|
|
2207 of XEmacs. Basically, XEmacs should have primitives to be told
|
|
|
2208 whether the terminal can handle international output, and which
|
|
|
2209 locale. Also, it should be able to do approximations of characters to
|
|
|
2210 the nearest supported by the locale.
|
|
|
2211
|
|
197
|
2212 ** Internationalized (Asian) Isearch doesn't work.
|
|
144
|
2213
|
|
|
2214 Currently, Isearch doesn't directly support any of the input methods
|
|
|
2215 that are not XIM based (like egg, canna and quail) (and there are
|
|
223
|
2216 potential problems with XIM version too...). If you're using egg
|
|
|
2217 there is a workaround. Hitting <RET> right after C-s to invoke
|
|
|
2218 Isearch will put Isearch in string mode, where a complete string can
|
|
|
2219 be typed into the minibuffer and then processed by Isearch afterwards.
|
|
|
2220 Since egg is now supported in the minibuffer using string mode you can
|
|
|
2221 now use egg to input your Japanese, Korean or Chinese string, then hit
|
|
|
2222 return to send that to Isearch and then use standard Isearch commands
|
|
|
2223 from there.
|
|
144
|
2224
|
|
223
|
2225 ** Using egg and mousing around while in 'fence' mode screws up my
|
|
|
2226 buffer.
|
|
144
|
2227
|
|
|
2228 Don't do this. The fence modes of egg and canna are currently very
|
|
|
2229 modal, and messing with where they expect point to be and what they
|
|
|
2230 think is the current buffer is just asking for trouble. If you're
|
|
|
2231 lucky they will realize that something is awry, and simply delete the
|
|
|
2232 fence, but worst case can trash other buffers too. We've tried to
|
|
|
2233 protect against this where we can, but there still are many ways to
|
|
|
2234 shoot yourself in the foot. So just finish what you are typing into
|
|
|
2235 the fence before reaching for the mouse.
|
|
223
|
2236
|
|
|
2237 ** Not all languages in Quail are supported like Devanagari and Indian
|
|
|
2238 languages, Lao and Tibetan.
|
|
|
2239
|
|
|
2240 Quail requires more work and testing. Although it has been ported to
|
|
|
2241 XEmacs, it works really well for Japanese and for the European
|
|
|
2242 languages.
|
|
|
2243
|
|
|
2244 ** Right-to-left mode is not yet implemented, so languages like
|
|
|
2245 Arabic, Hebrew and Thai don't work.
|
|
|
2246
|
|
|
2247 Getting this right requires more work. It may be implemented in a
|
|
|
2248 future XEmacs version, but don't hold your breath. If you know
|
|
|
2249 someone who is ready to implement this, please let us know.
|
|
|
2250
|
|
|
2251 ** We need more developers and native language testers. It's extremely
|
|
|
2252 difficult (and not particularly productive) to address languages that
|
|
|
2253 nobody is using and testing.
|
|
|
2254
|
|
|
2255 ** The kWnn and cWnn support for Chinese and Korean needs developers
|
|
|
2256 and testers. It probably doesn't work.
|
|
|
2257
|
|
|
2258 ** There are no `native XEmacs' TUTORIALs for any Asian languages,
|
|
454
|
2259 including Japanese. FSF Emacs and XEmacs tutorials are quite similar,
|
|
223
|
2260 so it should be sufficient to skim through the differences and apply
|
|
|
2261 them to the Japanese version.
|
|
|
2262
|
|
|
2263 ** We only have localized menus translated for Japanese, and the
|
|
|
2264 Japanese menus are developing bitrot (the Mule menu appears in
|
|
|
2265 English).
|
|
|
2266
|
|
|
2267 ** XIM is untested for any language other than Japanese.
