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:
|

|
11 - Problems with building XEmacs
|
|
12 - Problems with running XEmacs
|
|
13 - Compatibility problems
|
|
14 - Mule issues

|
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
|

|
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:
|
|
24 WATCH OUT for your init file! (~/.xemacs/init.el or ~/.emacs) If
|
|
25 you observe strange problems, invoke XEmacs with the `-vanilla'
|
|
26 option and see if you can repeat the problem.

|
32 ** General
|
394
|
33 *** Don't use -O2 with gcc 2.8.1 and egcs 1.0 under SPARC architectures
|
|
34 without also using `-fno-schedule-insns'.
|
|
35
|
|
36 gcc will generate incorrect code otherwise, typically resulting in
|
|
37 crashes in the function skip-syntax-backward.
|
|
38
|
382
|
39 *** egcs-1.1
|
|
40
|
|
41 There have been reports of egcs-1.1 not compiling XEmacs correctly on
|
|
42 Alpha Linux. There have also been reports that egcs-1.0.3a is O.K.
|
|
43
|
432
|
44 *** Don't use -O2 or -O3 with Cygwin 1.0, CodeFusion-99070 or gcc 2.7.2 on x86
|
|
45 without also using `-fno-strength-reduce'.
|
124
|
46
|
|
47 gcc will generate incorrect code otherwise. This bug is present in at
|
|
48 least 2.6.x and 2.7.[0-2]. This bug has been fixed in GCC 2.7.2.1 and
|
263
|
49 later. This bug is O/S independent, but is limited to x86 architectures.
|
|
50
|
|
51 This problem is known to be fixed in egcs (or pgcc) 1.0 or later.
|
229
|
52
|
432
|
53 Unfortunately, later releases of Cygnus-released compilers (not the
|
|
54 Net-released ones) have a bug with the same `problem signature'.
|
|
55
|
|
56 If you're lucky, you'll get an error while compiling that looks like:
|
|
57
|
|
58 event-stream.c:3189: internal error--unrecognizable insn:
|
|
59 (insn 256 14 15 (set (reg/v:SI 24)
|
|
60 (minus:SI (reg/v:SI 25)
|
|
61 (const_int 2))) -1 (insn_list 11 (nil))
|
|
62 (nil))
|
|
63 0 0 [main]
|
|
64
|
|
65 If you're unlucky, your code will simply execute incorrectly.
|
|
66
|
|
67 *** Don't use gcc-2.95.2 with -mcpu=ultrasparc on Solaris 2.6.
|
|
68
|
|
69 gcc will assume a 64-bit operating system, even though you've
|
|
70 merely told it to assume a 64-bit instruction set.
|
|
71
|
373
|
72 *** Don't use -O2 with gcc 2.7.2 under Intel architectures without also
|
229
|
73 using `-fno-caller-saves'.
|
|
74
|
263
|
75 gcc will generate incorrect code otherwise. This bug is still
|
|
76 present in gcc 2.7.2.3. There have been no reports to indicate the
|
|
77 bug is present in egcs 1.0 (or pgcc 1.0) or later. This bug is O/S
|
|
78 independent, but limited to x86 architectures.
|
|
79
|
|
80 This problem is known to be fixed in egcs (or pgcc) 1.0 or later.
|
124
|
81
|
373
|
82 *** When using gcc, you get the error message "undefined symbol __fixunsdfsi".
|
|
83 When using gcc, you get the error message "undefined symbol __main".
|
|
84
|
|
85 This means that you need to link with the gcc library. It may be called
|
|
86 "gcc-gnulib" or "libgcc.a"; figure out where it is, and define LIB_GCC in
|
|
87 config.h to point to it.
|
|
88
|
|
89 It may also work to use the GCC version of `ld' instead of the standard one.
|
|
90
|
|
91 *** Excessive optimization with pgcc can break XEmacs
|
124
|
92
|
|
93 It has been reported on some systems that compiling with -O6 can lead
|
|
94 to XEmacs failures. The workaround is to use a lower optimization
|
|
95 level. -O2 and -O4 have been tested extensively.
|
|
96
|
229
|
97 All of this depends heavily on the version of pgcc and the version
|
|
98 of libc. Snapshots near the release of pgcc-1.0 have been tested
|
|
99 extensively and no sign of breakage has been seen on systems using
|
|
100 glibc-2.
|
|
101
|
373
|
102 *** src/Makefile and lib-src/Makefile are truncated--most of the file missing.
|
229
|
103
|
373
|
104 This can happen if configure uses GNU sed version 2.03. That version
|
|
105 had a bug. GNU sed version 2.05 works properly.
|
124
|
106
|
373
|
107 *** When compiling with X11, you get "undefined symbol _XtStrings".
|
124
|
108
|
373
|
109 This means that you are trying to link emacs against the X11r4 version of
|
|
110 libXt.a, but you have compiled either Emacs or the code in the lwlib
|
|
111 subdirectory with the X11r5 header files. That doesn't work.
|
124
|
112
|
373
|
113 Remember, you can't compile lwlib for r4 and emacs for r5, or vice versa.
|
|
114 They must be in sync.
|
124
|
115
|
373
|
116 *** test-distrib says that the distribution has been clobbered
|
197
|
117 or, temacs prints "Command key out of range 0-127"
|
|
118 or, temacs runs and dumps xemacs, but xemacs totally fails to work.
|
|
119 or, temacs gets errors dumping xemacs
|
|
120
|
|
121 This can be because the .elc files have been garbled. Do not be
|
|
122 fooled by the fact that most of a .elc file is text: these are binary
|
|
123 files and can contain all 256 byte values.
|
|
124
|
|
125 In particular `shar' cannot be used for transmitting GNU Emacs. It
|
|
126 typically truncates "lines". (this does not apply to GNU shar, which
|
|
127 uses uuencode to encode binary files.)
|
|
128
|
|
129 If you have a copy of Emacs that has been damaged in its nonprinting
|
|
130 characters, you can fix them by running:
|
|
131
|
|
132 make all-elc
|
|
133
|
|
134 This will rebuild all the needed .elc files.
|
|
135
|
373
|
136 *** `compress' and `uncompress' not found and XFree86
|
|
137
|
|
138 XFree86 installs a very old version of libz.a by default ahead of where
|
|
139 more modern version of libz might be installed. This will cause problems
|
|
140 when attempting to link against libMagick. The fix is to remove the old
|
|
141 libz.a in the X11 binary directory.
|
|
142
|
|
143
|
|
144 ** AIX
|
|
145 *** On AIX 4.3, you must specify --with-dialogs=athena with configure
|
|
146
|
442
|
147 *** The libXt shipped with AIX 4.3 up to 4.3.2 is broken. This causes
|
|
148 xemacs -nw to fail in various ways. The official APAR is this:
|
|
149
|
|
150 APAR NUMBER: <IX89470> RESOLVED AS: PROGRAM ERROR
|
|
151
|
|
152 ABSTRACT:
|
|
153 <IX89470>: LIBXT.A INCORRECT HANDLING OF EXCEPTIONS IN XTAPPADDINPUT
|
|
154
|
|
155 The solution is to install X11.base.lib at version >=4.3.2.5.
|
392
|
156
|
373
|
157 *** On AIX, you get this compiler error message:
|
|
158
|
|
159 Processing include file ./XMenuInt.h
|
|
160 1501-106: (S) Include file X11/Xlib.h not found.
|
|
161
|
|
162 This means your system was installed with only the X11 runtime i.d
|
|
163 libraries. You have to find your sipo (bootable tape) and install
|
|
164 X11Dev... with smit.
|
|
165
|
|
166 *** On AIX 4.1.2, linker error messages such as
|
|
167 ld: 0711-212 SEVERE ERROR: Symbol .__quous, found in the global symbol table
|
|
168 of archive /usr/lib/libIM.a, was not defined in archive member shr.o.
|
|
169
|
|
170 This is a problem in libIM.a. You can work around it by executing
|
|
171 these shell commands in the src subdirectory of the directory where
|
|
172 you build Emacs:
|
|
173
|
|
174 cp /usr/lib/libIM.a .
|
|
175 chmod 664 libIM.a
|
|
176 ranlib libIM.a
|
|
177
|
|
178 Then change -lIM to ./libIM.a in the command to link temacs (in
|
|
179 Makefile).
|
|
180
|
|
181 *** Excessive optimization on AIX 4.2 can lead to compiler failure.

184 At least at the b34 level, and the latest-and-greatest IBM xlc

|
|
208 has been reported to solve the problem on Solaris 2.7:
|
|
209
|
|
210 107081-40 107656-07
|
|
211
|
|
212 For information (although they have not been confirmed to work), the
|
|
213 equivalent patches for Solaris 2.8 are:
|
|
214
|
|
215 108940-33 108652-25

217 *** Dumping error when using GNU binutils / GNU ld on a Sun.
|
|
218
|
|
219 Errors similar to the following:
|
|
220
|
|
221 Dumping under the name xemacs unexec():
|
|
222 dldump(/space/rpluim/xemacs-obj/src/xemacs): ld.so.1: ./temacs:
|
|
223 fatal: /space/rpluim/xemacs-obj/src/xemacs: unknown dynamic entry:
|
|
224 1879048176
|
|
225
|
|
226 are caused by using GNU ld. There are several workarounds available:
|
|
227
|
|
228 In XEmacs 21.2 or later, configure using the new portable dumper
|
|
229 (--pdump).
|
|
230
|
|
231 Alternatively, you can link using the Sun version of ld, which is
|
|
232 normally held in /usr/ccs/bin. This can be done by one of:
|
|
233
|
|
234 - building gcc with these configure flags:
|
|
235 configure --with-ld=/usr/ccs/bin/ld --with-as=/usr/ccs/bin/as
|
|
236
|
|
237 - adding -B/usr/ccs/bin/ to CFLAGS used to configure XEmacs
|
|
238 (Note: The trailing '/' there is significant.)
|
|
239
|
|
240 - uninstalling GNU ld.
|
|
241
|
|
242 The Solaris2 FAQ claims:
|
|
243
|
|
244 When you install gcc, don't make the mistake of installing
|
|
245 GNU binutils or GNU libc, they are not as capable as their
|
|
246 counterparts you get with Solaris 2.x.
|
|
247
|
373
|
248 *** Link failure when using acc on a Sun.
|
|
249
|
|
250 To use acc, you need additional options just before the libraries, such as
|
|
251
|
|
252 /usr/lang/SC2.0.1/values-Xt.o -L/usr/lang/SC2.0.1/cg87 -L/usr/lang/SC2.0.1
|
|
253
|
|
254 and you need to add -lansi just before -lc.
|
|
255
|
|
256 The precise file names depend on the compiler version, so we
|
|
257 cannot easily arrange to supply them.
|
|
258
|
|
259 *** Problems finding X11 libraries on Solaris with Openwindows
|
|
260
|
|
261 Some users have reported problems in this area. The reported solution
|
|
262 is to define the environment variable OPENWINHOME, even if you must set
|
|
263 it to `/usr/openwin'.
|
|
264
|
|
265 *** Sed problems on Solaris 2.5
|
|
266
|
|
267 There have been reports of Sun sed truncating very lines in the
|
|
268 Makefile during configuration. The workaround is to use GNU sed or,
|
454
|
269 even better, think of a better way to generate Makefile, and send us a
|
373
|
270 patch. :-)
|
|
271
|
|
272 *** On Solaris 2 I get undefined symbols from libcurses.a.
|
|
273
|
|
274 You probably have /usr/ucblib/ on your LD_LIBRARY_PATH. Do the link with
|
|
275 LD_LIBRARY_PATH unset. Generally, avoid using any ucb* stuff when
|
|
276 building XEmacs.
|
|
277
|
|
278 *** On Solaris 2 I cannot make alloc.o, glyphs.o or process.o.
|
|
279
|
|
280 The SparcWorks C compiler may have difficulty building those modules
|
|
281 with optimization level -xO4. Try using only "-fast" optimization
|
|
282 for just those modules. (Or use gcc).
|
|
283
|
|
284 *** Solaris 2.3 /bin/sh coredumps during configuration.
|
|
285
|
|
286 This only occurs if you have LANG != C. This is a known bug with
|
|
287 /bin/sh fixed by installing Patch-ID# 101613-01. Or, you can use
|
|
288 bash, as a workaround.
|
|
289
|
|
290 *** On SunOS, you get linker errors
|
454
|
291 ld: Undefined symbol
|
373
|
292 _get_wmShellWidgetClass
|
|
293 _get_applicationShellWidgetClass
|
|
294
|
|
295 The fix to this is to install patch 100573 for OpenWindows 3.0
|
|
296 or link libXmu statically.
|
|
297
|
|
298 *** On Sunos 4, you get the error ld: Undefined symbol __lib_version.
|
|
299
|
|
300 This is the result of using cc or gcc with the shared library meant
|
|
301 for acc (the Sunpro compiler). Check your LD_LIBRARY_PATH and delete
|
|
302 /usr/lang/SC2.0.1 or some similar directory.
|
|
303
|
|
304 *** Undefined symbols when linking on Sunos 4.1.
|
|
305
|
|
306 If you get the undefined symbols _atowc _wcslen, _iswprint, _iswspace,
|
|
307 _iswcntrl, _wcscpy, and _wcsncpy, then you need to add -lXwchar after
|
|
308 -lXaw in the command that links temacs.
|
|
309
|
|
310 This problem seems to arise only when the international language
|
|
311 extensions to X11R5 are installed.
|
|
312
|
|
313 *** On a Sun running SunOS 4.1.1, you get this error message from GNU ld:
|
|
314
|
454
|
315 /lib/libc.a(_Q_sub.o): Undefined symbol __Q_get_rp_rd referenced from text segment
|
373
|
316
|
|
317 The problem is in the Sun shared C library, not in GNU ld.
|
|
318
|
|
319 The solution is to install Patch-ID# 100267-03 from Sun.
|
|
320
|
|
321 *** SunOS 4.1.2: undefined symbol _get_wmShellWidgetClass
|
|
322
|
|
323 Apparently the version of libXmu.so.a that Sun ships is hosed: it's missing
|
454
|
324 some stuff that is in libXmu.a (the static version). Sun has a patch for
|
373
|
325 this, but a workaround is to use the static version of libXmu, by changing
|
|
326 the link command from "-lXmu" to "-Bstatic -lXmu -Bdynamic". If you have
|
|
327 OpenWindows 3.0, ask Sun for these patches:
|
|
328 100512-02 4.1.x OpenWindows 3.0 libXt Jumbo patch
|
|
329 100573-03 4.1.x OpenWindows 3.0 undefined symbols with shared libXmu
|
|
330
|
|
331 *** Random other SunOS 4.1.[12] link errors.
|
|
332
|
|
333 The X headers and libraries that Sun ships in /usr/{include,lib}/X11 are
|
|
334 broken. Use the ones in /usr/openwin/{include,lib} instead.
|
|
335
|
|
336 ** Linux
|
|
337 *** Under Linux, you get "too many arguments to function `getpgrp'".
|
|
338
|
|
339 You have probably installed LessTiff under `/usr/local' and `libXm.so'
|
|
340 could not be found when linking `getpgrp()' test program, making XEmacs
|
|
341 think that `getpgrp()' takes an argument. Try adding `/usr/local/lib'
|
|
342 in `/etc/ld.so.conf' and run `ldconfig'. Then run XEmacs's `configure'
|
|
343 again. As with all problems of this type, reading the config.log file
|
|
344 generated from configure and seeing the log of how the test failed can
|
|
345 prove enlightening.
|
|
346
|
|
347 *** `Error: No ExtNode to pop!' on Linux systems with Lesstif.
|
197
|
348
|
|
349 This error message has been observed with lesstif-0.75a. It does not
|
|
350 appear to cause any harm.

354 This is a Linux problem where you've compiled the XEmacs binary on a libc
|
|
355 5.4 with version higher than 5.4.19 and attempted to run the binary against
|
|
356 an earlier version. The solution is to upgrade your old library.

360 *** On Irix 6.5, the MIPSpro compiler gets an internal compiler error
|
|
361
|
|
362 The MIPSpro Compiler (at least version 7.2.1) can't seem to handle the
|
|
363 union type properly, and fails to compile src/glyphs.c. To avoid this
|
|
364 problem, always build ---use-union-type=no (but that's the default, so
|
|
365 you should only see this problem if you're an XEmacs maintainer).

370 There are a couple of problems [with use of -rpath with Irix ld], though:
|
|
371
|
|
372 1. The ld in IRIX 5.3 ignores all but the last -rpath
|
|
373 spec, so the patched configure spits out a warning
|
|
374 if --x-libraries or --site-runtime-libraries are
|
454
|
375 specified under irix 5.x, and it only adds -rpath
|
124
|
376 entries for the --site-runtime-libraries. This bug was
|
|
377 fixed sometime between 5.3 and 6.2.
|
|
378
|
|
379 2. IRIX gcc 2.7.2 doesn't accept -rpath directly, so
|
|
380 it would have to be prefixed by -Xlinker or "-Wl,".
|
|
381 This would be fine, except that configure compiles with
|
|
382 ${CC-cc} $CFLAGS $LDFLAGS ...
|
|
383 rather than quoting $LDFLAGS with prefix-args, like
|
|
384 src/Makefile does. So if you specify --x-libraries
|
|
385 or --site-runtime-libraries, you must use --use-gcc=no,
|
|
386 or configure will fail.

405 compiler_dev, or copy it from some other Irix 5.2 system. A kludgy

513 ** SCO OpenServer
|
|
514 *** Native cc on SCO OpenServer 5 is now OK. Icc may still throw you
|
197
|
515 a curve. Here is what Robert Lipe <robertl@arnet.com> says:
|
124
|
516
|
454
|
517 Unlike XEmacs 19.13, building with the native cc on SCO OpenServer 5
|
124
|
518 now produces a functional binary. I will typically build this
|
|
519 configuration for COFF with:
|
|
520
|
197
|
521 /path_to_xemacs_source/configure --with-gcc=no \
|
124
|
522 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
523 --with-xpm --with-xface --with-sound=nas
|
|
524
|
454
|
525 This version now supports ELF builds. I highly recommend this to
|
|
526 reduce the in-core footprint of XEmacs. This is now how I compile
|
124
|
527 all my test releases. Build it like this:
|
|
528
|
|
529 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
530 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
531 --with-xpm --with-xface --with-sound=nas --dynamic
|
|
532
|
454
|
533 The compiler known as icc [ supplied with the OpenServer 5 Development
|
124
|
534 System ] generates a working binary, but it takes forever to generate
|
|
535 XEmacs. ICC also whines more about the code than /bin/cc does. I do
|
|
536 believe all its whining is legitimate, however. Note that you do
|
|
537 have to 'cd src ; make LD=icc' to avoid linker errors.
|
|
538
|
|
539 The way I handle the build procedure is:
|
|
540
|
|
541 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
542 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
543 --with-xpm --with-xface --with-sound=nas --dynamic --compiler="icc"
|
|
544
|
454
|
545 NOTE I have the xpm, xface, and audio libraries and includes in
|
124
|
546 /usr/local/lib, /usr/local/include. If you don't have these,
|
|
547 don't include the "--with-*" arguments in any of my examples.
|
|
548
|
454
|
549 In previous versions of XEmacs, you had to override the defaults while
|
124
|
550 compiling font-lock.o and extents.o when building with icc. This seems
|
|
551 to no longer be true, but I'm including this old information in case it
|
|
552 resurfaces. The process I used was:
|
|
553
|
454
|
554 make -k
|
|
555 [ procure pizza, beer, repeat ]
|
124
|
556 cd src
|
|
557 make CC="icc -W0,-mP1COPT_max_tree_size=3000" font-lock.o extents.o
|
|
558 make LD=icc
|
|
559
|
454
|
560 If you want sound support, get the tls566 supplement from
|
|
561 ftp.sco.com:/TLS or any of its mirrors. It works just groovy
|
124
|
562 with XEmacs.
|
|
563
|
|
564 The M-x manual-entry is known not to work. If you know Lisp and would
|
|
565 like help in making it work, e-mail me at <robertl@dgii.com>.
|
|
566 (UNCHECKED for 19.15 -- it might work).
|
|
567
|
454
|
568 In earlier releases, gnuserv/gnuclient/gnudoit would open a frame
|
124
|
569 just fine, but the client would lock up and the server would
|
454
|
570 terminate when you used C-x # to close the frame. This is now
|
124
|
571 fixed in XEmacs.
|
|
572
|
|
573 In etc/ there are two files of note. emacskeys.sco and emacsstrs.sco.
|
|
574 The comments at the top of emacskeys.sco describe its function, and
|
|
575 the emacstrs.sco is a suitable candidate for /usr/lib/keyboard/strings
|
|
576 to take advantage of the keyboard map in emacskeys.sco.
|
|
577
|

207
|
579 and later.

585 The script etc/check_cygwin_setup.sh will attempt to detect whether

524
|
586 you have a suitable environment for building. This script may not work

590 in inexplicable situations, etc.

392

591
|
524
|
592 This may be because you are using the default cygwin shell. The
|
|
593 default cygwin shell (/bin/sh.exe) is ash which appears to work in
|
|
594 most circumstances but has some weird failure modes. You need to
|
|
595 replace the symlink with bash.exe.

600 Your partition holding the source files is mounted binary. It needs
|
|
601 to be mounted text. (This will not screw up any binary files because
|
|
602 the Cygwin utilities specify explicitly whether they want binary or
|
|
603 text mode when working with source vs. binary files, which overrides
|
|
604 the mount type.) To fix this, you just need to run the appropriate
|
|
605 mount command once -- afterwards, the settings are remembered in the
|
|
606 registry.

642 Thanks to giacomo boffi <giacomo.boffi@polimi.it> on comp.emacs.xemacs:
|

643

644 tell your ftp client to not attempt AUTH authentication (or do not
|
|
645 use FTP servers that don't understand AUTH)
|
|
646
|
|
647 and notes that you need to add an element (often "-u") to
|
|
648 `efs-ftp-program-args'. Use M-x customize-variable, and verify the
|
|
649 needed flag with `man ftp' or other local documentation.

|
651 *** gnuserv is running, some clients can connect, but others cannot.
|
|
652
|
|
653 The code in gnuslib.c respects the value of TMPDIR. If the server and
|
|
654 the client have different values in their environment, you lose.
|
|
655 One program known to set TMPDIR and manifest this problem is exmh.
|
|
656 You can defeat the use of TMPDIR by unsetting USE_TMPDIR at the top of
|
|
657 gnuserv.h at build time.
|
|
658
|
373
|
659 *** C-z just refreshes the screen instead of suspending Emacs.
|
124
|
660
|
|
661 You are probably using a shell that doesn't support job control, even
|
197
|
662 though the system itself is capable of it. Try using a different
|
|
663 shell.
|
124
|
664
|
373
|
665 *** You type Control-H (Backspace) expecting to delete characters.
|
124
|
666
|
|
667 Emacs has traditionally used Control-H for help; unfortunately this
|
424
|
668 interferes with its use as Backspace on TTY's. As of XEmacs 21,
|
|
669 XEmacs looks at the "erase" setting of TTY structures and maps C-h to
|
|
670 backspace when erase is set to C-h. This is sort of a special hack,
|
|
671 but it makes it possible for you to use the standard:
|
|
672
|
|
673 stty erase ^H
|
355
|
674
|
424
|
675 to get your backspace key to erase characters. The erase setting is
|
|
676 recorded in the Lisp variable `tty-erase-char', which you can use to
|
|
677 tune the settings in your .emacs.
|
124
|
678
|
424
|
679 A major drawback of this is that when C-h becomes backspace, it no
|
|
680 longer invokes help. In that case, you need to use f1 for help, or
|
|
681 bind another key. An example of the latter is the following code,
|
|
682 which moves help to Meta-? (ESC ?):
|
124
|
683
|
424
|
684 (global-set-key "\M-?" 'help-command)

688 rmail and VM get new mail from /usr/spool/mail/$USER using a program
|
|
689 called `movemail'. This program interlocks with /bin/mail using the
|
|
690 protocol defined by /bin/mail.
|
|
691
|
|
692 There are two different protocols in general use. One of them uses
|
|
693 the `flock' system call. The other involves creating a lock file;
|
|
694 `movemail' must be able to write in /usr/spool/mail in order to do
|
|
695 this. You control which one is used by defining, or not defining, the
|
|
696 macro MAIL_USE_FLOCK in config.h or the m- or s- file it includes. IF
|
|
697 YOU DON'T USE THE FORM OF INTERLOCKING THAT IS NORMAL ON YOUR SYSTEM,
|
|
698 YOU CAN LOSE MAIL!
|
|
699
|
|
700 If your system uses the lock file protocol, and fascist restrictions
|
|
701 prevent ordinary users from writing the lock files in /usr/spool/mail,
|
|
702 you may need to make `movemail' setgid to a suitable group such as
|
|
703 `mail'. To do this, use the following commands (as root) after doing
|
|
704 the make install.
|
|
705
|
|
706 chgrp mail movemail
|
|
707 chmod 2755 movemail
|
|
708
|
|
709 Installation normally copies movemail from the build directory to an
|
|
710 installation directory which is usually under /usr/local/lib. The
|
|
711 installed copy of movemail is usually in the directory
|
|
712 /usr/local/lib/emacs/VERSION/TARGET. You must change the group and
|
|
713 mode of the installed copy; changing the group and mode of the build
|
|
714 directory copy is ineffective.

749 then emacs won't be able to guess the names of the "bold" and "italic"

754 *** The dumped Emacs crashes when run, trying to write pure data.
|
0
|
755
|
|
756 Two causes have been seen for such problems.
|
|
757
|
|
758 1) On a system where getpagesize is not a system call, it is defined
|
|
759 as a macro. If the definition (in both unexec.c and malloc.c) is wrong,
|
|
760 it can cause problems like this. You might be able to find the correct
|
|
761 value in the man page for a.out (5).
|
|
762
|
|
763 2) Some systems allocate variables declared static among the
|
|
764 initialized variables. Emacs makes all initialized variables in most
|
|
765 of its files pure after dumping, but the variables declared static and
|
|
766 not initialized are not supposed to be pure. On these systems you
|
|
767 may need to add "#define static" to the m- or the s- file.

776 *** When emacs starts up, I get lots of warnings about unknown keysyms.
|
124
|
777
|
|
778 If you are running the prebuilt binaries, the Motif library expects to find
|
|
779 certain thing in the XKeysymDB file. This file is normally in /usr/lib/X11/
|
|
780 or in /usr/openwin/lib/. If you keep yours in a different place, set the
|
454
|
781 environment variable $XKEYSYMDB to point to it before starting emacs. If
|
|
782 you still have the problem after doing that, perhaps your version of X is
|
124
|
783 too old. There is a copy of the MIT X11R5 XKeysymDB file in the emacs `etc'
|
|
784 directory. Try using that one.

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

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

|
819
|
|
820 This means that Control-S/Control-Q (XON/XOFF) "flow control" is being
|
|
821 used. C-s/C-q flow control is bad for Emacs editors because it takes
|
|
822 away C-s and C-q as user commands. Since editors do not output long
|
|
823 streams of text without user commands, there is no need for a
|
|
824 user-issuable "stop output" command in an editor; therefore, a
|
|
825 properly designed flow control mechanism would transmit all possible
|
|
826 input characters without interference. Designing such a mechanism is
|
|
827 easy, for a person with at least half a brain.
|
|
828
|
|
829 There are three possible reasons why flow control could be taking place:
|
|
830
|
|
831 1) Terminal has not been told to disable flow control
|
|
832 2) Insufficient padding for the terminal in use
|
|
833 3) Some sort of terminal concentrator or line switch is responsible
|
|
834
|
|
835 First of all, many terminals have a set-up mode which controls whether
|
|
836 they generate XON/XOFF flow control characters. This must be set to
|
|
837 "no XON/XOFF" in order for Emacs to work. Sometimes there is an
|
|
838 escape sequence that the computer can send to turn flow control off
|
|
839 and on. If so, perhaps the termcap `ti' string should turn flow
|
|
840 control off, and the `te' string should turn it on.
|
|
841
|
|
842 Once the terminal has been told "no flow control", you may find it
|
|
843 needs more padding. The amount of padding Emacs sends is controlled
|
|
844 by the termcap entry for the terminal in use, and by the output baud
|
|
845 rate as known by the kernel. The shell command `stty' will print
|
|
846 your output baud rate; `stty' with suitable arguments will set it if
|
|
847 it is wrong. Setting to a higher speed causes increased padding. If
|
|
848 the results are wrong for the correct speed, there is probably a
|
|
849 problem in the termcap entry. You must speak to a local Unix wizard
|
|
850 to fix this. Perhaps you are just using the wrong terminal type.
|
|
851
|
|
852 For terminals that lack a "no flow control" mode, sometimes just
|
|
853 giving lots of padding will prevent actual generation of flow control
|
|
854 codes. You might as well try it.
|
|
855
|
|
856 If you are really unlucky, your terminal is connected to the computer
|
|
857 through a concentrator which sends XON/XOFF flow control to the
|
|
858 computer, or it insists on sending flow control itself no matter how
|
|
859 much padding you give it. Unless you can figure out how to turn flow
|
|
860 control off on this concentrator (again, refer to your local wizard),
|
|
861 you are screwed! You should have the terminal or concentrator
|
|
862 replaced with a properly designed one. In the mean time, some drastic
|
|
863 measures can make Emacs semi-work.
|
|
864
|
|
865 You can make Emacs ignore C-s and C-q and let the operating system
|
|
866 handle them. To do this on a per-session basis, just type M-x
|
|
867 enable-flow-control RET. You will see a message that C-\ and C-^ are
|
|
868 now translated to C-s and C-q. (Use the same command M-x
|
|
869 enable-flow-control to turn *off* this special mode. It toggles flow
|
|
870 control handling.)
|
|
871
|
|
872 If C-\ and C-^ are inconvenient for you (for example, if one of them
|
|
873 is the escape character of your terminal concentrator), you can choose
|
|
874 other characters by setting the variables flow-control-c-s-replacement
|
|
875 and flow-control-c-q-replacement. But choose carefully, since all
|
|
876 other control characters are already used by emacs.
|
|
877
|
|
878 IMPORTANT: if you type C-s by accident while flow control is enabled,
|
|
879 Emacs output will freeze, and you will have to remember to type C-q in
|
|
880 order to continue.
|
|
881
|
|
882 If you work in an environment where a majority of terminals of a
|
|
883 certain type are flow control hobbled, you can use the function
|
|
884 `enable-flow-control-on' to turn on this flow control avoidance scheme
|
|
885 automatically. Here is an example:
|
|
886
|
|
887 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")
|
|
888
|
|
889 If this isn't quite correct (e.g. you have a mixture of flow-control hobbled
|
|
890 and good vt200 terminals), you can still run enable-flow-control
|
|
891 manually.
|
|
892
|
|
893 I have no intention of ever redesigning the Emacs command set for the
|
|
894 assumption that terminals use C-s/C-q flow control. XON/XOFF flow
|
|
895 control technique is a bad design, and terminals that need it are bad
|
|
896 merchandise and should not be purchased. Now that X is becoming
|
|
897 widespread, XON/XOFF seems to be on the way out. If you can get some
|
|
898 use out of GNU Emacs on inferior terminals, more power to you, but I
|
|
899 will not make Emacs worse for properly designed systems for the sake
|
|
900 of inferior systems.

902 *** Control-S and Control-Q commands are ignored completely.
|
0
|
903
|
|
904 For some reason, your system is using brain-damaged C-s/C-q flow
|
|
905 control despite Emacs's attempts to turn it off. Perhaps your
|
|
906 terminal is connected to the computer through a concentrator
|
|
907 that wants to use flow control.
|
|
908
|
|
909 You should first try to tell the concentrator not to use flow control.
|
|
910 If you succeed in this, try making the terminal work without
|
|
911 flow control, as described in the preceding section.
|
|
912
|
|
913 If that line of approach is not successful, map some other characters
|
|
914 into C-s and C-q using keyboard-translate-table. The example above
|
|
915 shows how to do this with C-^ and C-\.

|
|
920 Some versions of rlogin (and possibly telnet) do not pass flow
|
|
921 control characters to the remote system to which they connect.
|
|
922 On such systems, emacs on the remote system cannot disable flow
|
|
923 control on the local system.
|
|
924
|
|
925 One way to cure this is to disable flow control on the local host
|
|
926 (the one running rlogin, not the one running rlogind) using the
|
|
927 stty command, before starting the rlogin process. On many systems,
|
120
|
928 `stty start u stop u' will do this.
|
0
|
929
|
|
930 Some versions of tcsh will prevent even this from working. One way
|
|
931 around this is to start another shell before starting rlogin, and
|
|
932 issue the stty command to disable flow control from that shell.
|
|
933
|
|
934 If none of these methods work, the best solution is to type
|
120
|
935 `M-x enable-flow-control' at the beginning of your emacs session, or
|
0
|
936 if you expect the problem to continue, add a line such as the
|
|
937 following to your .emacs (on the host running rlogind):

|

|
939 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")

197

945
|

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

|
951

0

960

|
961 The first step in tracking this down is to record what characters
|
|
962 Emacs is sending to the terminal. Execute the Lisp expression
|
120
|
963 (open-termscript "./emacs-script") to make Emacs write all terminal
|
|
964 output into the file ~/emacs-script as well; then do what makes the
|
|
965 screen update wrong, and look at the file and decode the characters
|
|
966 using the manual for the terminal. There are several possibilities:
|
0
|
967
|
|
968 1) The characters sent are correct, according to the terminal manual.
|
|
969
|
|
970 In this case, there is no obvious bug in Emacs, and most likely you
|
|
971 need more padding, or possibly the terminal manual is wrong.
|
|
972
|
120
|
973 2) The characters sent are incorrect, due to an obscure aspect of the
|
|
974 terminal behavior not described in an obvious way by termcap.
|
0
|
975
|
120
|
976 This case is hard. It will be necessary to think of a way for Emacs
|
|
977 to distinguish between terminals with this kind of behavior and other
|
|
978 terminals that behave subtly differently but are classified the same
|
|
979 by termcap; or else find an algorithm for Emacs to use that avoids the
|
|
980 difference. Such changes must be tested on many kinds of terminals.

985 needed in commonly used termcap entries for certain terminals.

1003 You can tell it to obey them with this command in your `.twmrc' file:

1010 This has been traced to communicating with your machine via kermit,
|
|
1011 with C-\ as the kermit escape character. One solution is to use
|
|
1012 another escape character in kermit. One user did

1031 Some versions of SVR4 have a serious bug in the implementation of the
|
|
1032 mmap () system call in the kernel; this causes emacs to run correctly
|
|
1033 the first time, and then crash when run a second time.
|
|
1034
|
|
1035 Contact your vendor and ask for the mmap bug fix; in the mean time,
|
|
1036 you may be able to work around the problem by adding a line to your
|
|
1037 operating system description file (whose name is reported by the
|
|
1038 configure script) that reads:
|
|
1039 #define SYSTEM_MALLOC
|
|
1040 This makes Emacs use memory less efficiently, but seems to work around
|
|
1041 the kernel bug.

1043 *** Inability to send an Alt-modified key, when Emacs is communicating
|
|
1044 directly with an X server.
|
|
1045
|
|
1046 If you have tried to bind an Alt-modified key as a command, and it
|
|
1047 does not work to type the command, the first thing you should check is
|
|
1048 whether the key is getting through to Emacs. To do this, type C-h c
|
|
1049 followed by the Alt-modified key. C-h c should say what kind of event
|
|
1050 it read. If it says it read an Alt-modified key, then make sure you
|
|
1051 have made the key binding correctly.
|
|
1052
|
|
1053 If C-h c reports an event that doesn't have the Alt modifier, it may
|
|
1054 be because your X server has no key for the Alt modifier. The X
|
|
1055 server that comes from MIT does not set up the Alt modifier by
|
|
1056 default.
|
|
1057
|
|
1058 If your keyboard has keys named Alt, you can enable them as follows:
|
|
1059
|
|
1060 xmodmap -e 'add mod2 = Alt_L'
|
|
1061 xmodmap -e 'add mod2 = Alt_R'
|
|
1062
|
|
1063 If the keyboard has just one key named Alt, then only one of those
|
|
1064 commands is needed. The modifier `mod2' is a reasonable choice if you
|
|
1065 are using an unmodified MIT version of X. Otherwise, choose any
|
|
1066 modifier bit not otherwise used.
|
|
1067
|
|
1068 If your keyboard does not have keys named Alt, you can use some other
|
|
1069 keys. Use the keysym command in xmodmap to turn a function key (or
|
|
1070 some other 'spare' key) into Alt_L or into Alt_R, and then use the
|
|
1071 commands show above to make them modifier keys.
|
|
1072
|
|
1073 Note that if you have Alt keys but no Meta keys, Emacs translates Alt
|
|
1074 into Meta. This is because of the great importance of Meta in Emacs.
|
|
1075
|
|
1076 *** In Shell mode, you get a ^M at the end of every line.
|
|
1077
|
|
1078 This happens to people who use tcsh, because it is trying to be too
|
|
1079 smart. It sees that the Shell uses terminal type `unknown' and turns
|
|
1080 on the flag to output ^M at the end of each line. You can fix the
|
|
1081 problem by adding this to your .cshrc file:
|
|
1082
|
|
1083 if ($?EMACS) then
|
|
1084 if ($EMACS == "t") then
|
454
|
1085 unset edit
|
373
|

|
|
1092
|
|
1093 This comes from having an invalid X resource, such as
|
|
1094 emacs*Cursor: black
|
|
1095 (which is invalid because it specifies a color name for something
|
|
1096 that isn't a color.)

1100 *** Once you pull down a menu from the menubar, it won't go away.
|
|
1101
|
|
1102 It has been claimed that this is caused by a bug in certain very old
|
|
1103 (1990?) versions of the twm window manager. It doesn't happen with
|
|
1104 recent vintages, or with other window managers.

1105
|
|
1106 *** Emacs ignores the "help" key when running OLWM.
|
|
1107
|
|
1108 OLWM grabs the help key, and retransmits it to the appropriate client
|
|
1109 using XSendEvent. Allowing emacs to react to synthetic events is a
|
|
1110 security hole, so this is turned off by default. You can enable it by
|
|
1111 setting the variable x-allow-sendevents to t. You can also cause fix
|
|
1112 this by telling OLWM to not grab the help key, with the null binding
|
|
1113 "OpenWindows.KeyboardCommand.Help:".

|
1115 *** Programs running under terminal emulator do not recognize `emacs'
|
|
1116 terminal type.
|
|
1117
|
|
1118 The cause of this is a shell startup file that sets the TERMCAP
|
|
1119 environment variable. The terminal emulator uses that variable to
|
|
1120 provide the information on the special terminal type that Emacs
|
|
1121 emulates.
|
|
1122
|
|
1123 Rewrite your shell startup file so that it does not change TERMCAP
|
|
1124 in such a case. You could use the following conditional which sets
|
|
1125 it only if it is undefined.
|
|
1126
|
|
1127 if ( ! ${?TERMCAP} ) setenv TERMCAP ~/my-termcap-file
|
|
1128
|
|
1129 Or you could set TERMCAP only when you set TERM--which should not
|
|
1130 happen in a non-login shell.

1198 you have probably compiled using an ANSI C compiler, but with non-ANSI

1199 include files. In particular, on Suns, the file
|
|
1200 /usr/include/sun/audioio.h uses the _IOW macro to define the constant
|
|
1201 AUDIOSETQSIZE. _IOW in turn uses a K&R preprocessor feature that is
|
|
1202 now explicitly forbidden in ANSI preprocessors, namely substitution
|
|
1203 inside character constants. All ANSI C compilers must provide a
|
|
1204 workaround for this problem. Lucid's C compiler is shipped with a new
|
|
1205 set of system include files. If you are using GCC, there is a script
|
|
1206 called fixincludes that creates new versions of some system include
|
|
1207 files that use this obsolete feature.

1227 casper@fwi.uva.nl says the problem is in X11R6. Rebuild libX11.so

1231 #define SharedX11Reqs -lthread
|
|

1239 #endif

|
|
1241
|
|
1242 Be sure also to edit x/config/cf/sun.cf so that OSMinorVersion is 4
|
|
1243 (as it should be for Solaris 2.4). The file has three definitions for
|
|
1244 OSMinorVersion: the first is for x86, the second for SPARC under

|
0
|
1274
|
124
|
1275 Many emacs mail user agents (VM and rmail, for instance) use the
|
|
1276 sendmail.el library. This library can arrange for mail to be
|
|
1277 delivered by passing messages to the /usr/lib/sendmail (usually)
|
|
1278 program . In doing so, it passes the '-t' flag to sendmail, which
|
|
1279 means that the name of the recipient of the message is not on the
|
|
1280 command line and, therefore, that sendmail must parse the message to
|
|
1281 obtain the destination address.
|
|
1282
|
|
1283 There is a bug in the SunOS4.1.1 and SunOS4.1.3 versions of sendmail.
|
|
1284 In short, when given the -t flag, the SunOS sendmail won't recognize
|
|
1285 non-local (i.e. NIS) aliases. It has been reported that the Solaris
|
|
1286 2.x versions of sendmail do not have this bug. For those using SunOS
|
|
1287 4.1, the best fix is to install sendmail V8 or IDA sendmail (which
|
|
1288 have other advantages over the regular sendmail as well). At the time
|
|
1289 of this writing, these official versions are available:
|

|
1291 Sendmail V8 on ftp.cs.berkeley.edu in /ucb/sendmail:

1304

124
|
1305 This typically happens on Suns and other systems that use shared
|
|
1306 libraries. The cause is that the site has installed a version of the
|
|
1307 shared library which uses a name server--but has not installed a
|
|
1308 similar version of the unshared library which Emacs uses.
|
0
|
1309
|
124
|
1310 The result is that most programs, using the shared library, work with
|
|
1311 the nameserver, but Emacs does not.
|
|
1312
|
|
1313 The fix is to install an unshared library that corresponds to what you
|

1314 installed in the shared library, and then relink Emacs.

1318 If you have already installed the name resolver in the file libresolv.a,
|
|
1319 then you need to compile Emacs to use that library. The easiest way to
|
|
1320 do this is to add to config.h a definition of LIBS_SYSTEM, LIBS_MACHINE
|
|
1321 or LIB_STANDARD which uses -lresolv. Watch out! If you redefine a macro
|
|
1322 that is already in use in your configuration to supply some other libraries,
|
|
1323 be careful not to lose the others.
|
|
1324
|
|
1325 Thus, you could start by adding this to config.h:
|
|
1326
|
|
1327 #define LIBS_SYSTEM -lresolv
|
|
1328
|
|
1329 Then if this gives you an error for redefining a macro, and you see that
|
|
1330 the s- file defines LIBS_SYSTEM as -lfoo -lbar, you could change config.h
|
|
1331 again to say this:
|
|
1332
|
|
1333 #define LIBS_SYSTEM -lresolv -lfoo -lbar

1338 On SunOS systems, this problem has been seen to be a result of an

1349 make-frame(nil #<x-device on ":0.0" 0x2558>)
|
|
1350
|
|
1351 somewhere near the top. The problem is due to an improvement in GNU
|
|
1352 ld that sorts the ELF reloc sections in the executable, giving
|
|
1353 dramatic speedups in startup for large executables. It also confuses
|
|
1354 the traditional unexec code in XEmacs, leading to the core dump. The
|
|
1355 solution is to use the --pdump or --ldflags='-z nocombreloc' options
|
|
1356 to configure. Recent 21.4 and 12.5 autodetect this in configure.
|
|
1357
|
|
1358 Red Hat and SuSE (at least) distributed a prerelease version of ld
|
|
1359 (versions around 2.11.90.x.y) where autodetection is impossible. The
|
|
1360 recommended procedure is to upgrade to binutils >= 2.12 and rerun

1364 *** I want XEmacs to use the Alt key, not the XXX key, for Meta commands
|
|
1365
|
|
1366 For historical reasons, XEmacs looks for a Meta key, then an Alt key.
|
|
1367 It binds Meta commands to the X11 modifier bit attached to the first
|
|
1368 of these it finds. On PCs, the Windows key is often assigned the Meta
|
|
1369 bit, but many desktop environments go to great lengths to get all apps
|
|
1370 to use the Alt key, and reserve the Windows key to (sensibly enough)
|
|
1371 the window manager.
|
|
1372
|
|
1373 One correct way to implement this was suggested on comp.emacs.xemacs

1374 (by Kilian Foth and in more detail by Michael Piotrowski): unmap the
|
|
1375 Meta modifier using xmodmap or xkb, and then map the Meta/Windows key
|
450
|
1376 to the Super or Hyper keysym and an appropriate mod bit. XEmacs will
|
|
1377 not find the Meta keysym, and default to using the Alt key for Meta
|
|
1378 keybindings. Typically few applications use the (X11) Meta modifier;
|
|
1379 it is tedious but not too much so to teach the ones you need to use
|
|
1380 Super instead of Meta. There may be further useful hints in the
|
|
1381 discussion of keymapping on non-Linux platforms.

1383 *** The color-gcc wrapper
|
|
1384
|
|
1385 This wrapper colorizes the error messages from gcc. By default XEmacs
|
|
1386 does not interpret the escape sequences used to generate colors,
|
|
1387 resulting in a cluttered, hard-to-read buffer. You can remove the
|
|
1388 wrapper, or defeat the wrapper colorization in Emacs process buffers
|
|
1389 by editing the "nocolor" attribute in /etc/colorgccrc:
|
|
1390
|
|
1391 $ diff -u /etc/colorgccrc.old /etc/colorgccrc
|
|
1392 --- /etc/colorgccrc.old Tue Dec 26 02:17:46 2000

1406 *** Slow startup on Linux.
|
|
1407
|
|
1408 People using systems based on the Linux kernel sometimes report that
|
448
|
1409 startup takes 10 to 15 seconds longer than `usual'. There are two
|
|
1410 problems, one older, one newer.
|
|
1411
|
|
1412 **** Old problem: IPv4 host lookup
|
373
|
1413
|
448
|
1414 On older systems, this is because Emacs looks up the host name when it
|
|
1415 starts. Normally, this takes negligible time; the extra delay is due
|
|
1416 to improper system configuration. (Recent Linux distros usually have
|
|
1417 this configuration correct "out of the box".) This problem can occur
|
|
1418 for both networked and non-networked machines.
|
373
|
1419
|
|
1420 Here is how to fix the configuration. It requires being root.
|
|
1421
|
448
|
1422 ***** Networked Case
|
373
|
1423
|
|
1424 First, make sure the files `/etc/hosts' and `/etc/host.conf' both
|
|
1425 exist. The first line in the `/etc/hosts' file should look like this
|
|
1426 (replace HOSTNAME with your host name):
|
|
1427
|
|
1428 127.0.0.1 localhost HOSTNAME
|
|
1429
|
|
1430 Also make sure that the `/etc/host.conf' files contains the following
|
|
1431 lines:
|
|
1432
|
454
|
1433 order hosts, bind
|
373
|
1434 multi on
|
|
1435
|
|
1436 Any changes, permanent and temporary, to the host name should be
|
|
1437 indicated in the `/etc/hosts' file, since it acts a limited local
|
|
1438 database of addresses and names (e.g., some SLIP connections
|
|
1439 dynamically allocate ip addresses).
|
|
1440
|
448
|
1441 ***** Non-Networked Case
|
373
|
1442
|
|
1443 The solution described in the networked case applies here as well.
|
|
1444 However, if you never intend to network your machine, you can use a
|
|
1445 simpler solution: create an empty `/etc/host.conf' file. The command
|
|
1446 `touch /etc/host.conf' suffices to create the file. The `/etc/hosts'
|
|
1447 file is not necessary with this approach.
|
|
1448
|
448
|
1449 **** New problem: IPv6 CNAME lookup
|
|
1450
|
|
1451 A newer problem is due to XEmacs changing to use the modern
|
|
1452 getaddrinfo() interface from the older gethostbyname() interface. The
|
|
1453 solution above is insufficient, because getaddrinfo() by default tries
|
|
1454 to get IPv6 information for localhost. This always involves a dns
|
|
1455 lookup to get the CNAME, and the strategies above don't work. It then
|
724
|
1456 falls back to IPv4 behavior. This is good[tm] according the people at
|
|
1457 WIDE who know about IPv6.
|
448
|
1458
|
|
1459 ***** Robust network case
|
|
1460
|
|
1461 Configure your network so that there are no nameservers configured
|
|
1462 until the network is actually running. getaddrinfo() will not try to
|
|
1463 access a nameserver that isn't configured.
|
|
1464
|
|
1465 ***** Flaky network case
|
|
1466
|
|
1467 If you have a flaky modem or DSL connection that can be relied on only
|
|
1468 to go down whenever you want to bring XEmacs up, you need to force
|
|
1469 IPv4 behavior. Explicitly setting DISPLAY=127.0.0.1:0.0 (or whatever
|
|
1470 is appropriate) works in most cases.
|
|
1471
|
|
1472 If you cannot or do not want to do that, you can hard code IPv4
|
|
1473 behavior in src/process-unix.c. This is bad[tm], on your own head be
|
724
|
1474 it. Use the configure option `--with-ipv6-cname=no'.
|
373
|
1475
|
845
|
1476 *** Mandrake
|
|
1477
|
|
1478 The Mandrake Linux distribution is attempting to comprehensively
|
|
1479 update the user interface, and make it consistent across
|
|
1480 applications. This is very difficult, and will occasionally cause
|
|
1481 conflicts with applications like Emacs with their own long-established
|
|
1482 interfaces. Known issues specific to Mandrake or especially common:
|
|
1483
|
|
1484 Some versions of XEmacs (21.1.9 is known) distributed with Mandrake
|
|
1485 were patched to make the Meta and Alt keysyms synonymous. These
|
|
1486 normally work as expected in the Mandrake environment. However,
|
|
1487 custom-built XEmacsen (including all 21.2 betas) will "inexplicably"
|
|
1488 not respect the "Alt-invokes-Meta-commands" convention. See "I want
|
|
1489 XEmacs to use the Alt key" below.
|
|
1490
|
|
1491 The color-gcc wrapper (see below) is in common use on the Mandrake
|
|
1492 platform.
|
|
1493
|
|
1494 *** You get crashes in a non-C locale with Linux GNU Libc 2.0.
|
|
1495
|
|
1496 Internationalization was not the top priority for GNU Libc 2.0.
|
|
1497 As of this writing (1998-12-28) you may get crashes while running
|
|
1498 XEmacs in a non-C locale. For example, `LC_ALL=en_US xemacs' crashes
|
|
1499 while `LC_ALL=C xemacs' runs fine. This happens for example with GNU
|
|
1500 libc 2.0.7. Installing libintl.a and libintl.h built from gettext
|
|
1501 0.10.35 and re-building XEmacs solves the crashes. Presumably soon
|
|
1502 everyone will upgrade to GNU Libc 2.1 and this problem will go away.
|
|
1503
|
|
1504 *** `C-z', or `M-x suspend-emacs' hangs instead of suspending.
|
|
1505
|
|
1506 If you build with `gpm' support on Linux, you cannot suspend XEmacs
|
|
1507 because gpm installs a buggy SIGTSTP handler. Either compile with
|
|
1508 `--with-gpm=no', or don't suspend XEmacs on the Linux console until
|
|
1509 this bug is fixed.
|
|
1510
|
|
1511 *** With certain fonts, when the cursor appears on a character, the
|
|
1512 character doesn't appear--you get a solid box instead.
|
|
1513
|
|
1514 One user on a Linux system reported that this problem went away with
|
|
1515 installation of a new X server. The failing server was XFree86 3.1.1.
|
|
1516 XFree86 3.1.2 works.

1518 ** IRIX

1519 *** On Irix, I don't see the toolbar icons and I'm getting lots of
|
|
1520 entries in the warnings buffer.
|
|
1521
|
|
1522 SGI ships a really old Xpm library in /usr/lib which does not work at
|
|
1523 all well with XEmacs. The solution is to install your own copy of the
|
|
1524 latest version of Xpm somewhere and then use the --site-includes and
|
|
1525 --site-libraries flags to tell configure where to find it.
|
|
1526
|
|
1527 *** Trouble using ptys on IRIX, or running out of ptys.
|
|
1528
|
|
1529 The program mkpts (which may be in `/usr/adm' or `/usr/sbin') needs to
|
|
1530 be set-UID to root, or non-root programs like Emacs will not be able
|
|
1531 to allocate ptys reliably.

1550 ** Digital UNIX/OSF/VMS/Ultrix
|
|
1551 *** XEmacs crashes on Digital Unix within font-lock, or when dealing
|
|
1552 with large compilation buffers.
|
|
1553
|
|
1554 The default stack size under Digital Unix is rather small (2M as
|
|
1555 opposed to Solaris 8M), hosing the regexp code, which uses alloca()
|
|
1556 extensively, overflowing the stack when complex regexps are used.
|
|
1557 Workarounds:
|
312
|
1558
|
373
|
1559 1) Increase your stack size, using `ulimit -s 8192' or a (t)csh
|
|
1560 equivalent;
|
|
1561
|
|
1562 2) Recompile regex.c with REGEX_MALLOC defined.
|
|
1563
|
|
1564 *** The `Alt' key doesn't behave as `Meta' when running DECwindows.
|
|
1565
|
|
1566 The default DEC keyboard mapping has the Alt keys set up to generate the
|
|
1567 keysym `Multi_key', which has a meaning to xemacs which is distinct from that
|
|
1568 of the `Meta_L' and `Meta-R' keysyms. A second problem is that certain keys
|
|
1569 have the Mod2 modifier attached to them for no adequately explored reason.
|
|
1570 The correct fix is to pass this file to xmodmap upon starting X:
|
|
1571
|
|
1572 clear mod2
|
|
1573 keysym Multi_key = Alt_L
|
|
1574 add mod1 = Alt_L
|
|
1575 add mod1 = Alt_R
|
|
1576
|
|
1577 *** The Compose key on a DEC keyboard does not work as Meta key.
|
|
1578
|
|
1579 This shell command should fix it:
|
|
1580
|
|
1581 xmodmap -e 'keycode 0xb1 = Meta_L'
|
|
1582
|
|
1583 *** `expand-file-name' fails to work on any but the machine you dumped
|
|
1584 Emacs on.
|
|
1585
|
|
1586 On Ultrix, if you use any of the functions which look up information
|
|
1587 in the passwd database before dumping Emacs (say, by using
|
|
1588 expand-file-name in site-init.el), then those functions will not work
|
|
1589 in the dumped Emacs on any host but the one Emacs was dumped on.
|
|
1590
|
|
1591 The solution? Don't use expand-file-name in site-init.el, or in
|
|
1592 anything it loads. Yuck - some solution.
|
|
1593
|
|
1594 I'm not sure why this happens; if you can find out exactly what is
|
|
1595 going on, and perhaps find a fix or a workaround, please let us know.
|
|
1596 Perhaps the YP functions cache some information, the cache is included
|
|
1597 in the dumped Emacs, and is then inaccurate on any other host.

1601 *** I get complaints about the mapping of my HP keyboard at startup,
|
|
1602 but I haven't changed anything.
|
|
1603
|
|
1604 The default HP keymap is set up to have Mod1 assigned to two different keys:
|
|
1605 Meta_L and Mode_switch (even though there is not actually a Mode_switch key on
|
|
1606 the keyboard -- it uses an "imaginary" keycode.) There actually is a reason
|
|
1607 for this, but it's not a good one. The correct fix is to execute this command
|
|
1608 upon starting X:
|
|
1609
|
|
1610 xmodmap -e 'remove mod1 = Mode_switch'
|

1655 *** XEmacs dumps core at startup when native audio is used. Native
|
|
1656 audio does not work with recent versions of HP-UX.
|
|
1657
|
|
1658 Under HP-UX 10.20 and later (e.g., HP-UX 11.XX), with native audio
|
|
1659 enabled, the dumped XEmacs binary ("xemacs") core dumps at startup if
|
|
1660 recent versions of the libAlib.sl audio shared library is used. Note
|
|
1661 that "temacs" will run, but "xemacs" will dump core. This, of course,
|
|
1662 causes the XEmacs build to fail. If GNU malloc is enabled, a stack
|
|
1663 trace will show XEmacs to have crashed in the "first" call to malloc().
|
|
1664
|
|
1665 This bug currently exists in all versions of XEmacs, when the undump
|
|
1666 mechanism is used. It is not known if using the experimental portable
|
|
1667 dumper will allow native audio to work.
|
|
1668
|
|
1669 **** Cause:
|
|
1670
|
|
1671 Recent versions of the HP-UX 10.20 (and later) audio shared library (in
|
|
1672 /opt/audio/lib), pulls in the libdce shared library, which pulls in a
|
|
1673 thread (libcma) library. This prevents the HP-UX undump() routine (in
|
|
1674 unexhp9k800.c) from properly working. What's happening is that some
|
|
1675 initialization routines are being called in the libcma library, *BEFORE*
|
|
1676 main() is called, and these initialization routines are calling
|
|
1677 malloc(). Unfortunately, in order for the undumper to work, XEmacs must
|
|
1678 adjust (move upwards) the sbrk() value *BEFORE* the first call to
|
|
1679 malloc(); if malloc() is called before XEmacs has properly adjusted sbrk
|
|
1680 (which is what is happening), dumped memory that is being used by
|
|
1681 XEmacs, is improperly re-allocated for use by malloc() and the dumped
|
|
1682 memory is corrupted. This causes XEmacs to die an horrible death.
|
|
1683
|
|
1684 It is believed that versions of the audio library past December 1998
|
|
1685 will trigger this problem. Under HP-UX 10.20, you probably have to
|
|
1686 install audio library patches to encounter this. It's probable that
|
|
1687 recent "fresh, out-of-the-box" HP-UX 11.XX workstations also have this
|
|
1688 problem. For HP-UX 10.20, it's believed that audio patch PHSS_17121 (or
|
|
1689 a superceeding one, like PHSS_17554, PHSS_17971, PHSS_18777, PHSS_21481,
|
|
1690 or PHSS_21662, etc.) will trigger this.
|
|
1691
|
|
1692 To check if your audio library will cause problems for XEmacs, run
|
|
1693 "chatr /opt/audio/lib/libAlib.sl". If "libdce" appears in the displayed
|
|
1694 shared library list, XEmacs will probably encounter problems if audio is
|
|
1695 enabled.
|
|
1696
|
|
1697 **** Workaround:
|
|
1698
|
|
1699 Don't enable native audio. Re-run configure without native audio
|
|
1700 support.
|
|
1701
|
|
1702 If your site supports it, try using NAS (Network Audio Support).
|
|
1703
|
|
1704 Try using the experimental portable dumper. It may work, or it may
|
|
1705 not.

1720
|
|
1721 The problem is that in your .cshrc you have something that tries to
|
197
|
1722 execute `tty`. If you are not running the shell on a real tty then tty
|
|
1723 will print "not a tty". Csh expects one word in some places, but tty
|
|
1724 is giving it back 3.
|
124
|
1725
|
197
|
1726 The solution is to add a pair of quotes around `tty` to make it a
|
|
1727 single word:
|
0
|
1728
|
454
|
1729 if (`tty` == "/dev/console")
|
124
|
1730
|
|
1731 should be changed to:
|
|
1732
|
454
|
1733 if ("`tty`" == "/dev/console")
|
124
|
1734
|
|
1735 Even better, move things that set up terminal sections out of .cshrc
|
|
1736 and into .login.

1759

1760 You do not have "tty" in your CYGWIN environment variable. This must

1761 be set in your autoexec.bat (win95) or the system properties (winnt)

1762 as it must be read before the cygwin DLL initializes.

1766 This is a known problem. It can be remedied by defining BROKEN_SIGIO
|

1767 in src/s/cygwin.h, however this currently leads to instability in XEmacs.

1783 * Compatibility problems (with Emacs 18, GNU Emacs, or previous XEmacs/lemacs)
|
197
|
1784 ==============================================================================
|
88
|
1785
|
373
|
1786 *** "Symbol's value as variable is void: unread-command-char".
|
197
|
1787 "Wrong type argument: arrayp, #<keymap 143 entries>"
|
|
1788 "Wrong type argument: stringp, [#<keypress-event return>]"
|
88
|
1789
|
124
|
1790 There are a few incompatible changes in XEmacs, and these are the
|
|
1791 symptoms. Some of the emacs-lisp code you are running needs to be
|
|
1792 updated to be compatible with XEmacs.
|
|
1793
|
|
1794 The code should not treat keymaps as arrays (use `define-key', etc.),
|
|
1795 should not use obsolete variables like `unread-command-char' (use
|
197
|
1796 `unread-command-events'). Many (most) of the new ways of doing things
|
124
|
1797 are compatible in GNU Emacs and XEmacs.
|
88
|
1798
|
197
|
1799 Modern Emacs packages (Gnus, VM, W3, efs, etc) are written to support
|
|
1800 GNU Emacs and XEmacs. We have provided modified versions of several
|
|
1801 popular emacs packages (dired, etc) which are compatible with this
|
|
1802 version of emacs. Check to make sure you have not set your load-path
|
|
1803 so that your private copies of these packages are being found before
|
|
1804 the versions in the lisp directory.
|
124
|
1805
|
|
1806 Make sure that your load-path and your $EMACSLOADPATH environment
|
|
1807 variable are not pointing at an Emacs18 lisp directory. This will
|
|
1808 cripple emacs.

1810 ** Some packages that worked before now cause the error
|
223
|
1811 Wrong type argument: arrayp, #<face ... >
|
124
|
1812
|
197
|
1813 Code which uses the `face' accessor functions must be recompiled with
|
|
1814 xemacs 19.9 or later. The functions whose callers must be recompiled
|
|
1815 are: face-font, face-foreground, face-background,
|
|
1816 face-background-pixmap, and face-underline-p. The .elc files
|
|
1817 generated by version 19.9 will work in 19.6 and 19.8, but older .elc
|
|
1818 files which contain calls to these functions will not work in 19.9.

1820 ** Signaling: (error "Byte code stack underflow (byte compiler bug), pc 38")
|
88

120
|
1822 This error is given when XEmacs 20 is compiled without MULE support
|
88
|
1823 but is attempting to load a .elc which requires MULE support. The fix
|
|
1824 is to rebytecompile the offending file.

1829 which includes an outdated copy of mail-abbrevs.el. Remove the copy

1833 * MULE issues
|
197
|
1834 =============
|
144
|
1835
|
223
|
1836 ** A reminder: XEmacs/Mule work does not currently receive *any*
|
|
1837 funding, and all work is done by volunteers. If you think you can
|
|
1838 help, please contact the XEmacs maintainers.
|
|
1839
|
278
|
1840 ** XEmacs/Mule doesn't support TTY's satisfactorily.
|
223
|
1841
|
|
1842 This is a major problem, which we plan to address in a future release
|
|
1843 of XEmacs. Basically, XEmacs should have primitives to be told
|
|
1844 whether the terminal can handle international output, and which
|
|
1845 locale. Also, it should be able to do approximations of characters to
|
|
1846 the nearest supported by the locale.
|
|
1847
|
197
|
1848 ** Internationalized (Asian) Isearch doesn't work.
|
144
|
1849
|
|
1850 Currently, Isearch doesn't directly support any of the input methods
|
|
1851 that are not XIM based (like egg, canna and quail) (and there are
|
223
|
1852 potential problems with XIM version too...). If you're using egg
|
|
1853 there is a workaround. Hitting <RET> right after C-s to invoke
|
|
1854 Isearch will put Isearch in string mode, where a complete string can
|
|
1855 be typed into the minibuffer and then processed by Isearch afterwards.
|
|
1856 Since egg is now supported in the minibuffer using string mode you can
|
|
1857 now use egg to input your Japanese, Korean or Chinese string, then hit
|
|
1858 return to send that to Isearch and then use standard Isearch commands
|
|
1859 from there.
|
144
|
1860
|
223
|
1861 ** Using egg and mousing around while in 'fence' mode screws up my
|
|
1862 buffer.
|
144
|
1863
|
|
1864 Don't do this. The fence modes of egg and canna are currently very
|
|
1865 modal, and messing with where they expect point to be and what they
|
|
1866 think is the current buffer is just asking for trouble. If you're
|
|
1867 lucky they will realize that something is awry, and simply delete the
|
|
1868 fence, but worst case can trash other buffers too. We've tried to
|
|
1869 protect against this where we can, but there still are many ways to
|
|
1870 shoot yourself in the foot. So just finish what you are typing into
|
|
1871 the fence before reaching for the mouse.
|
223
|
1872
|
|
1873 ** Not all languages in Quail are supported like Devanagari and Indian
|
|
1874 languages, Lao and Tibetan.
|
|
1875
|
|
1876 Quail requires more work and testing. Although it has been ported to
|
|
1877 XEmacs, it works really well for Japanese and for the European
|
|
1878 languages.
|
|
1879
|
|
1880 ** Right-to-left mode is not yet implemented, so languages like
|
|
1881 Arabic, Hebrew and Thai don't work.
|
|
1882
|
|
1883 Getting this right requires more work. It may be implemented in a
|
|
1884 future XEmacs version, but don't hold your breath. If you know
|
|
1885 someone who is ready to implement this, please let us know.
|
|
1886
|
|
1887 ** We need more developers and native language testers. It's extremely
|
|
1888 difficult (and not particularly productive) to address languages that
|
|
1889 nobody is using and testing.
|
|
1890
|
|
1891 ** The kWnn and cWnn support for Chinese and Korean needs developers
|
|
1892 and testers. It probably doesn't work.
|
|
1893
|
|
1894 ** There are no `native XEmacs' TUTORIALs for any Asian languages,
|
454
|
1895 including Japanese. FSF Emacs and XEmacs tutorials are quite similar,
|
223
|
1896 so it should be sufficient to skim through the differences and apply
|
|
1897 them to the Japanese version.
|
|
1898
|
|
1899 ** We only have localized menus translated for Japanese, and the
|
|
1900 Japanese menus are developing bitrot (the Mule menu appears in
|
|
1901 English).
|
|
1902
|
|
1903 ** XIM is untested for any language other than Japanese.
