6 This file is large, but we have tried to sort the entries by their
|
|
7 respective relevance for XEmacs, but may have not succeeded completely
|
197
|
8 in that task. The file is divided into four parts:
|
124

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

|
15 Use `C-c C-f' to move to the next equal level of outline, and
|
223
|
16 `C-c C-b' to move to previous equal level. `C-h m' will give more
|
|
17 info about the Outline mode.
|
120
|
18
|
197
|
19 Also, Try finding the things you need using one of the search commands
|
|
20 XEmacs provides (e.g. `C-s').
|
|
21
|
|
22 A general advice:
|
|
23 WATCH OUT for .emacs file! ~/.emacs is your Emacs init file. If
|
|
24 you observe strange problems, invoke XEmacs with the `-q' option
|
|
25 and see if you can repeat the problem.

31 ** Don't use -O2 with gcc 2.7.2 under Intel/XXX without also using
|
223
|
32 `-fno-strength-reduce'.
|
124
|
33
|
|
34 gcc will generate incorrect code otherwise. This bug is present in at
|
|
35 least 2.6.x and 2.7.[0-2]. This bug has been fixed in GCC 2.7.2.1 and
|
229
|
36 later. This bug is also O/S independent.
|
|
37
|
|
38 ** Don't use -O2 with gcc 2.7.2 under Intel architectures without also
|
|
39 using `-fno-caller-saves'.
|
|
40
|
|
41 gcc will generate incorrect code otherwise. This bug is still present
|
|
42 in gcc 2.7.2.3. There have been no reports to indicate the bug is
|
|
43 present in egcs 1.0 (or pgcc 1.0) or later. This bug is O/S independent.
|
124
|
44
|
|
45 ** Excessive optimization with pgcc can break XEmacs
|
|
46
|
|
47 It has been reported on some systems that compiling with -O6 can lead
|
|
48 to XEmacs failures. The workaround is to use a lower optimization
|
|
49 level. -O2 and -O4 have been tested extensively.
|
|
50
|
229
|
51 All of this depends heavily on the version of pgcc and the version
|
|
52 of libc. Snapshots near the release of pgcc-1.0 have been tested
|
|
53 extensively and no sign of breakage has been seen on systems using
|
|
54 glibc-2.
|
|
55
|
|
56 ** `compress' and `uncompress' not found and XFree86
|
|
57
|
|
58 XFree86 installs a very old version of libz.a by default ahead of where
|
|
59 more modern version of libz might be installed. This will cause problems
|
|
60 when attempting to link against libMagick. The fix is to remove the old
|
|
61 libz.a in the X11 binary directory.
|
124
|
62
|
|
63 ** Excessive optimization on AIX 4.2 can lead to compiler failure.

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

67 (3.1.4.4), there are problems with -O3. I haven't investigated
|
|
68 further.
|
|
69
|
|
70 ** Sed problems on Solaris 2.5
|
|
71
|
|
72 There have been reports of Sun sed truncating very lines in the
|
|
73 Makefile during configuration. The workaround is to use GNU sed or,
|
|
74 even better, think of a better way to generate Makefile, and send us a
|
|
75 patch. :-)

76

|
77 ** test-distrib says that the distribution has been clobbered
|
|
78 or, temacs prints "Command key out of range 0-127"
|
|
79 or, temacs runs and dumps xemacs, but xemacs totally fails to work.
|
|
80 or, temacs gets errors dumping xemacs
|
|
81
|
|
82 This can be because the .elc files have been garbled. Do not be
|
|
83 fooled by the fact that most of a .elc file is text: these are binary
|
|
84 files and can contain all 256 byte values.
|
|
85
|
|
86 In particular `shar' cannot be used for transmitting GNU Emacs. It
|
|
87 typically truncates "lines". (this does not apply to GNU shar, which
|
|
88 uses uuencode to encode binary files.)
|
|
89
|
|
90 If you have a copy of Emacs that has been damaged in its nonprinting
|
|
91 characters, you can fix them by running:
|
|
92
|
|
93 make all-elc
|
|
94
|
|
95 This will rebuild all the needed .elc files.

|
|
97 ** `Error: No ExtNode to pop!' on Linux systems with Lesstif.
|
|
98
|
|
99 This error message has been observed with lesstif-0.75a. It does not
|
|
100 appear to cause any harm.
|

|
124
|
102 ** Linking with -rpath on IRIX.
|
|
103
|
|
104 Darrell Kindred <dkindred@cmu.edu> writes:
|
|
105 There are a couple of problems [with use of -rpath with Irix ld], though:
|
|
106
|
|
107 1. The ld in IRIX 5.3 ignores all but the last -rpath
|
|
108 spec, so the patched configure spits out a warning
|
|
109 if --x-libraries or --site-runtime-libraries are
|
|
110 specified under irix 5.x, and it only adds -rpath
|
|
111 entries for the --site-runtime-libraries. This bug was
|
|
112 fixed sometime between 5.3 and 6.2.
|
|
113
|
|
114 2. IRIX gcc 2.7.2 doesn't accept -rpath directly, so
|
|
115 it would have to be prefixed by -Xlinker or "-Wl,".
|
|
116 This would be fine, except that configure compiles with
|
|
117 ${CC-cc} $CFLAGS $LDFLAGS ...
|
|
118 rather than quoting $LDFLAGS with prefix-args, like
|
|
119 src/Makefile does. So if you specify --x-libraries
|
|
120 or --site-runtime-libraries, you must use --use-gcc=no,
|
|
121 or configure will fail.
|
|
122
|
207
|
123 ** On Irix 6.3, the SGI ld quits with segmentation fault when linking temacs
|
|
124
|
|
125 This occurs if you use the SGI linker version 7.1. Installing the
|
|
126 patch SG0001872 fixes this problem.
|
197
|
127
|
124
|
128 ** xemacs: can't resolve symbol '__malloc_hook'
|
|
129
|
|
130 This is a Linux problem where you've compiled the XEmacs binary on a libc
|
|
131 5.4 with version higher than 5.4.19 and attempted to run the binary against
|
|
132 an earlier version. The solution is to upgrade your old library.
|
|
133
|
|
134 ** Compilation errors on VMS.
|
|
135
|
|
136 Sorry, XEmacs does not work under VMS. You might consider working on
|
|
137 the port if you really want to have XEmacs work under VMS.
|
|
138
|
197
|
139 ** On Solaris 2 I get undefined symbols from libcurses.a.
|
124
|
140
|
|
141 You probably have /usr/ucblib/ on your LD_LIBRARY_PATH. Do the link with
|
197
|
142 LD_LIBRARY_PATH unset. Generally, avoid using any ucb* stuff when
|
|
143 building XEmacs.
|
124
|
144
|
197
|
145 ** On Solaris 2 I cannot make alloc.o, glyphs.o or process.o.
|
124
|
146
|
|
147 The SparcWorks C compiler may have difficulty building those modules
|
|
148 with optimization level -xO4. Try using only "-fast" optimization
|
|
149 for just those modules. (Or use gcc).
|
|
150
|
|
151 ** On Digital UNIX, the DEC C compiler might have a problem compiling
|
197
|
152 some files.
|
124
|
153
|
|
154 In particular, src/extents.c and src/faces.c might cause the DEC C
|
|
155 compiler to abort. When this happens: cd src, compile the files by
|
|
156 hand, cd .., and redo the "make" command. When recompiling the files by
|
|
157 hand, use the old C compiler for the following versions of Digital UNIX:
|
|
158 - V3.n: Remove "-migrate" from the compile command.
|
|
159 - V4.n: Add "-oldc" to the compile command.
|
|
160
|
197
|
161 A related compiler bug has been fixed by the DEC compiler team. The
|
|
162 new versions of the compiler should run fine.
|
126
|
163
|
124
|
164 ** On HPUX, the HP C compiler might have a problem compiling some files
|
|
165 with optimization.

|

|
|
168
|
|
169 Had to drop once again to level 2 optimization, at least to
|
|
170 compile lstream.c. Otherwise, I get a "variable is void: \if"
|
|
171 problem while dumping (this is a problem I already reported
|
|
172 with vanilla hpux 10.01 and 9.07, which went away after
|
|
173 applying patches for the C compiler). Trouble is I still
|
|
174 haven't found the same patch for hpux 10.10, and I don't
|
|
175 remember the patch numbers. I think potential XEmacs builders
|
|
176 on HP should be warned about this.
|
|
177
|
|
178 ** I don't have `xmkmf' and `imake' on my HP.
|
|
179
|
|
180 You can get these standard X tools by anonymous FTP to hpcvaaz.cv.hp.com.
|
|
181 Essentially all X programs need these.
|
|
182
|
|
183 ** Solaris 2.3 /bin/sh coredumps during configuration.
|
|
184
|
|
185 This only occurs if you have LANG != C. This is a known bug with
|
197
|
186 /bin/sh fixed by installing Patch-ID# 101613-01. Or, you can use
|
|
187 bash, as a workaround.
|
124
|
188
|
|
189 ** On Irix 6.0, make tries (and fails) to build a program named unexelfsgi
|
|
190
|
|
191 A compiler bug inserts spaces into the string "unexelfsgi . o"
|
|
192 in src/Makefile. Edit src/Makefile, after configure is run,
|
|
193 find that string, and take out the spaces.
|
|
194
|
|
195 Compiler fixes in Irix 6.0.1 should eliminate this problem.
|
|
196
|
|
197 ** Native cc on SCO OpenServer 5 is now OK. Icc may still throw you
|
197
|
198 a curve. Here is what Robert Lipe <robertl@arnet.com> says:
|
124
|
199
|
|
200 Unlike XEmacs 19.13, building with the native cc on SCO OpenServer 5
|
|
201 now produces a functional binary. I will typically build this
|
|
202 configuration for COFF with:
|
|
203
|
197
|
204 /path_to_xemacs_source/configure --with-gcc=no \
|
124
|
205 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
206 --with-xpm --with-xface --with-sound=nas
|
|
207
|
|
208 This version now supports ELF builds. I highly recommend this to
|
|
209 reduce the in-core footprint of XEmacs. This is now how I compile
|
|
210 all my test releases. Build it like this:
|
|
211
|
|
212 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
213 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
214 --with-xpm --with-xface --with-sound=nas --dynamic
|
|
215
|
|
216 The compiler known as icc [ supplied with the OpenServer 5 Development
|
|
217 System ] generates a working binary, but it takes forever to generate
|
|
218 XEmacs. ICC also whines more about the code than /bin/cc does. I do
|
|
219 believe all its whining is legitimate, however. Note that you do
|
|
220 have to 'cd src ; make LD=icc' to avoid linker errors.
|
|
221
|
|
222 The way I handle the build procedure is:
|
|
223
|
|
224 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
225 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
226 --with-xpm --with-xface --with-sound=nas --dynamic --compiler="icc"
|
|
227
|
|
228 NOTE I have the xpm, xface, and audio libraries and includes in
|
|
229 /usr/local/lib, /usr/local/include. If you don't have these,
|
|
230 don't include the "--with-*" arguments in any of my examples.
|
|
231
|
|
232 In previous versions of XEmacs, you had to override the defaults while
|
|
233 compiling font-lock.o and extents.o when building with icc. This seems
|
|
234 to no longer be true, but I'm including this old information in case it
|
|
235 resurfaces. The process I used was:
|
|
236
|
|
237 make -k
|
|
238 [ procure pizza, beer, repeat ]
|
|
239 cd src
|
|
240 make CC="icc -W0,-mP1COPT_max_tree_size=3000" font-lock.o extents.o
|
|
241 make LD=icc
|
|
242
|
|
243 If you want sound support, get the tls566 supplement from
|
|
244 ftp.sco.com:/TLS or any of its mirrors. It works just groovy
|
|
245 with XEmacs.
|
|
246
|
|
247 The M-x manual-entry is known not to work. If you know Lisp and would
|
|
248 like help in making it work, e-mail me at <robertl@dgii.com>.
|
|
249 (UNCHECKED for 19.15 -- it might work).
|
|
250
|
|
251 In earlier releases, gnuserv/gnuclient/gnudoit would open a frame
|
|
252 just fine, but the client would lock up and the server would
|
|
253 terminate when you used C-x # to close the frame. This is now
|
|
254 fixed in XEmacs.
|
|
255
|
|
256 In etc/ there are two files of note. emacskeys.sco and emacsstrs.sco.
|
|
257 The comments at the top of emacskeys.sco describe its function, and
|
|
258 the emacstrs.sco is a suitable candidate for /usr/lib/keyboard/strings
|
|
259 to take advantage of the keyboard map in emacskeys.sco.
|
|
260
|
227
|
261 Note: Much of the above entry is probably not valid for XEmacs 20.5
|
207
|
262 and later.
|
197
|
263
|
124
|
264 ** Under some versions of OSF XEmacs runs fine if built without
|
197
|
265 optimization but will crash randomly if built with optimization.
|
124
|
266
|
|
267 Using 'cc -g' is not sufficient to eliminate all optimization. Try
|
|
268 'cc -g -O0' instead.
|
|
269
|
|
270 ** On SunOS, you get linker errors
|
|
271 ld: Undefined symbol
|
|
272 _get_wmShellWidgetClass
|
|
273 _get_applicationShellWidgetClass
|
|
274
|
|
275 The fix to this is to install patch 100573 for OpenWindows 3.0
|
|
276 or link libXmu statically.
|
|
277
|
|
278 ** On Sunos 4, you get the error ld: Undefined symbol __lib_version.
|
|
279
|
|
280 This is the result of using cc or gcc with the shared library meant
|
|
281 for acc (the Sunpro compiler). Check your LD_LIBRARY_PATH and delete
|
|
282 /usr/lang/SC2.0.1 or some similar directory.
|
|
283
|
|
284 ** On AIX 4.1.2, linker error messages such as
|
|
285 ld: 0711-212 SEVERE ERROR: Symbol .__quous, found in the global symbol table
|
|
286 of archive /usr/lib/libIM.a, was not defined in archive member shr.o.
|
|
287
|
|
288 This is a problem in libIM.a. You can work around it by executing
|
|
289 these shell commands in the src subdirectory of the directory where
|
|
290 you build Emacs:
|
|
291
|
|
292 cp /usr/lib/libIM.a .
|
|
293 chmod 664 libIM.a
|
|
294 ranlib libIM.a
|
|
295
|
|
296 Then change -lIM to ./libIM.a in the command to link temacs (in
|
|
297 Makefile).
|
|
298
|
|
299 ** On Irix 5.2, unexelfsgi.c can't find cmplrs/stsupport.h.
|
|
300
|
|
301 The file cmplrs/stsupport.h was included in the wrong file set in the
|
|
302 Irix 5.2 distribution. You can find it in the optional fileset
|
|
303 compiler_dev, or copy it from some other Irix 5.2 system. A kludgy
|
|
304 workaround is to change unexelfsgi.c to include sym.h instead of
|
|
305 syms.h.
|
|
306
|
|
307 ** Link failure when using acc on a Sun.
|
|
308
|
|
309 To use acc, you need additional options just before the libraries, such as
|
|
310
|
|
311 /usr/lang/SC2.0.1/values-Xt.o -L/usr/lang/SC2.0.1/cg87 -L/usr/lang/SC2.0.1
|
|
312
|
|
313 and you need to add -lansi just before -lc.
|
|
314
|
|
315 The precise file names depend on the compiler version, so we
|
|
316 cannot easily arrange to supply them.
|
|
317
|
|
318 ** Link failure on IBM AIX 1.3 ptf 0013.
|
|
319
|
|
320 There is a real duplicate definition of the function `_slibc_free' in
|
|
321 the library /lib/libc_s.a (just do nm on it to verify). The
|
|
322 workaround/fix is:
|
|
323
|
|
324 cd /lib
|
|
325 ar xv libc_s.a NLtmtime.o
|
|
326 ar dv libc_s.a NLtmtime.o
|
|
327
|
|
328 ** Undefined symbols when linking on Sunos 4.1.
|
|
329
|
|
330 If you get the undefined symbols _atowc _wcslen, _iswprint, _iswspace,
|
|
331 _iswcntrl, _wcscpy, and _wcsncpy, then you need to add -lXwchar after
|
|
332 -lXaw in the command that links temacs.
|
|
333
|
|
334 This problem seems to arise only when the international language
|
|
335 extensions to X11R5 are installed.
|
|
336
|
|
337 ** src/Makefile and lib-src/Makefile are truncated--most of the file missing.
|
|
338
|
|
339 This can happen if configure uses GNU sed version 2.03. That version
|
|
340 had a bug. GNU sed version 2.05 works properly.
|
|
341
|
|
342 ** On AIX, you get this compiler error message:
|
|
343
|
|
344 Processing include file ./XMenuInt.h
|
|
345 1501-106: (S) Include file X11/Xlib.h not found.
|
|
346
|
|
347 This means your system was installed with only the X11 runtime i.d
|
|
348 libraries. You have to find your sipo (bootable tape) and install
|
|
349 X11Dev... with smit.
|
|
350
|
|
351 ** C-z just refreshes the screen instead of suspending Emacs.
|
|
352
|
|
353 You are probably using a shell that doesn't support job control, even
|
197
|
354 though the system itself is capable of it. Try using a different
|
|
355 shell.
|
124
|
356
|
|
357 ** On a Sun running SunOS 4.1.1, you get this error message from GNU ld:

|
361 The problem is in the Sun shared C library, not in GNU ld.
|
|
362
|
|
363 The solution is to install Patch-ID# 100267-03 from Sun.
|
|
364
|
|
365 ** SunOS 4.1.2: undefined symbol _get_wmShellWidgetClass
|
|
366
|
|
367 Apparently the version of libXmu.so.a that Sun ships is hosed: it's missing
|
|
368 some stuff that is in libXmu.a (the static version). Sun has a patch for
|
|
369 this, but a workaround is to use the static version of libXmu, by changing
|
|
370 the link command from "-lXmu" to "-Bstatic -lXmu -Bdynamic". If you have
|
|
371 OpenWindows 3.0, ask Sun for these patches:
|
|
372 100512-02 4.1.x OpenWindows 3.0 libXt Jumbo patch
|
|
373 100573-03 4.1.x OpenWindows 3.0 undefined symbols with shared libXmu
|
|
374
|
|
375 ** Random other SunOS 4.1.[12] link errors.
|
|
376
|
|
377 The X headers and libraries that Sun ships in /usr/{include,lib}/X11 are
|
|
378 broken. Use the ones in /usr/openwin/{include,lib} instead.
|
|
379
|
|
380 ** When using gcc, you get the error message "undefined symbol __fixunsdfsi".
|
197
|
381 When using gcc, you get the error message "undefined symbol __main".
|
124
|
382
|
|
383 This means that you need to link with the gcc library. It may be called
|
|
384 "gcc-gnulib" or "libgcc.a"; figure out where it is, and define LIB_GCC in
|
|
385 config.h to point to it.
|
|
386
|
|
387 It may also work to use the GCC version of `ld' instead of the standard one.
|
|
388
|
|
389 ** When compiling with X11, you get "undefined symbol _XtStrings".
|
|
390
|
|
391 This means that you are trying to link emacs against the X11r4 version of
|
|
392 libXt.a, but you have compiled either Emacs or the code in the lwlib
|
|
393 subdirectory with the X11r5 header files. That doesn't work.
|
|
394
|
|
395 Remember, you can't compile lwlib for r4 and emacs for r5, or vice versa.
|
|
396 They must be in sync.
|
|
397
|
136
|
398 ** Problems finding X11 libraries on Solaris with Openwindows
|
|
399
|
|
400 Some users have reported problems in this area. The reported solution
|
|
401 is to define the environment variable OPENWINHOME, even if you must set
|
|
402 it to `/usr/openwin'.
|
|
403
|
251
|
404 ** Under Linux, you get "too many arguments to function `getpgrp'".
|
|
405
|
|
406 You have probably installed LessTiff under `/usr/local' and `libXm.so'
|
|
407 could not be found when linking `getpgrp()' test program, making XEmacs
|
|
408 think that `getpgrp()' takes an argument. Try adding `/usr/local/lib'
|
|
409 in `/etc/ld.so.conf' and run `ldconfig'. Then run XEmacs's `configure'
|
|
410 again. As with all problems of this type, reading the config.log file
|
|
411 generated from configure and seeing the log of how the test failed can
|
|
412 prove enlightening.

415 * Problems with running XEmacs
|
197
|
416 ==============================
|
124
|
417
|
259
|
418 ** `C-z', or `M-x suspend-emacs' hangs instead of suspending.
|
|
419
|
|
420 If you build with `gpm' support on Linux, you cannot suspend XEmacs
|
|
421 because gpm installs a buggy SIGTSTP handler. Either compile with
|
|
422 `--with-gpm=no', or don't suspend XEmacs on the Linux console until
|
|
423 this bug is fixed.
|
|
424
|
124
|
425 ** You type Control-H (Backspace) expecting to delete characters.
|
|
426
|
|
427 Emacs has traditionally used Control-H for help; unfortunately this
|
|
428 interferes with its use as Backspace on TTY's. One way to solve this
|
|
429 problem is to put this in your .emacs:
|
|
430
|
197
|
431 (when (eq tty-erase-char ?\C-h)
|
|
432 (keyboard-translate ?\C-h ?\C-?)
|
|
433 (global-set-key "\M-?" 'help-command))
|
124
|
434
|
197
|
435 This checks whether the TTY erase char is C-h, and if it is, makes
|
|
436 Control-H (Backspace) work sensibly, and moves help to Meta-? (ESC ?).
|
124
|
437
|
|
438 Note that you can probably also access help using F1.
|
|
439
|
197
|
440 ** Mail agents (VM, Gnus, rmail) cannot get new mail
|
|
441
|
|
442 rmail and VM get new mail from /usr/spool/mail/$USER using a program
|
|
443 called `movemail'. This program interlocks with /bin/mail using the
|
|
444 protocol defined by /bin/mail.
|
|
445
|
|
446 There are two different protocols in general use. One of them uses
|
|
447 the `flock' system call. The other involves creating a lock file;
|
|
448 `movemail' must be able to write in /usr/spool/mail in order to do
|
|
449 this. You control which one is used by defining, or not defining, the
|
|
450 macro MAIL_USE_FLOCK in config.h or the m- or s- file it includes. IF
|
|
451 YOU DON'T USE THE FORM OF INTERLOCKING THAT IS NORMAL ON YOUR SYSTEM,
|
|
452 YOU CAN LOSE MAIL!
|
|
453
|
|
454 If your system uses the lock file protocol, and fascist restrictions
|
|
455 prevent ordinary users from writing the lock files in /usr/spool/mail,
|
|
456 you may need to make `movemail' setgid to a suitable group such as
|
|
457 `mail'. To do this, use the following commands (as root) after doing
|
|
458 the make install.
|
|
459
|
|
460 chgrp mail movemail
|
|
461 chmod 2755 movemail
|
|
462
|
|
463 Installation normally copies movemail from the build directory to an
|
|
464 installation directory which is usually under /usr/local/lib. The
|
|
465 installed copy of movemail is usually in the directory
|
|
466 /usr/local/lib/emacs/VERSION/TARGET. You must change the group and
|
|
467 mode of the installed copy; changing the group and mode of the build
|
|
468 directory copy is ineffective.
|
|
469
|
203
|
470 ** XEmacs crashes on Digital Unix when dealing with large compilation
|
|
471 buffers.
|
|
472
|
|
473 This is a known problem with the regexp code, that uses alloca
|
|
474 extensively, and overflows the stack in case of complex regexp
|
|
475 matches. As a workaround, you can recompile with REGEX_MALLOC
|
|
476 defined.

477
|
124
|
478 ** On Solaris, C-x doesn't get through to Emacs when you use the console.
|
|
479
|
|
480 This is a Solaris feature (at least on Intel x86 cpus). Type C-r
|
|
481 C-r C-t, to toggle whether C-x gets through to Emacs.
|
|
482
|
197
|
483 ** VM appears to hang in large folders.
|
124
|
484
|
|
485 This is normal (trust us) when upgrading to VM-6.22 from earlier
|
|
486 versions. Let VM finish what it is doing and all will be well.

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

500

197
|
501 The fonts of the "bold" and "italic" faces are generated from the font

502 of the "default" face; in this way, your bold and italic fonts will
|
|
503 have the appropriate size and family. However, emacs can only be
|
|
504 clever in this way if you have specified the default font using the
|
|
505 XLFD (X Logical Font Description) format, which looks like
|
0
|
506
|
|
507 *-courier-medium-r-*-*-*-120-*-*-*-*-*-*
|

508

513 and fixed

|
514 and 9x13
|
|
515
|
|
516 then emacs won't be able to guess the names of the "bold" and "italic"
|
|
517 versions. All X fonts can be referred to via XLFD-style names, so you
|
|
518 should use those forms. See the man pages for X(1), xlsfonts(1), and

519 xfontsel(1).

521 ** The dumped Emacs crashes when run, trying to write pure data.
|
0
|
522
|
|
523 Two causes have been seen for such problems.
|
|
524
|
|
525 1) On a system where getpagesize is not a system call, it is defined
|
|
526 as a macro. If the definition (in both unexec.c and malloc.c) is wrong,
|
|
527 it can cause problems like this. You might be able to find the correct
|
|
528 value in the man page for a.out (5).
|
|
529
|
|
530 2) Some systems allocate variables declared static among the
|
|
531 initialized variables. Emacs makes all initialized variables in most
|
|
532 of its files pure after dumping, but the variables declared static and
|
|
533 not initialized are not supposed to be pure. On these systems you
|
|
534 may need to add "#define static" to the m- or the s- file.
|
|
535
|
124
|
536 ** Reading and writing files is very very slow.
|
0
|
537
|
|
538 Try evaluating the form (setq lock-directory nil) and see if that helps.
|
|
539 There is a problem with file-locking on some systems (possibly related
|
|
540 to NFS) that I don't understand. Please send mail to the address
|
|
541 xemacs@xemacs.org if you figure this one out.
|
|
542
|
124
|
543 ** The Emacs window disappears when you type M-q.
|
|
544
|
|
545 Some versions of the Open Look window manager interpret M-q as a quit
|
|
546 command for whatever window you are typing at. If you want to use
|
|
547 Emacs with that window manager, you should try to configure the window
|
|
548 manager to use some other command. You can disable the
|
|
549 shortcut keys entirely by adding this line to ~/.OWdefaults:
|
|
550
|
|
551 OpenWindows.WindowMenuAccelerators: False
|
|
552
|
|
553 ** The `Alt' key doesn't behave as `Meta' when running DECwindows.
|
|
554
|
|
555 The default DEC keyboard mapping has the Alt keys set up to generate the
|
|
556 keysym `Multi_key', which has a meaning to xemacs which is distinct from that
|
|
557 of the `Meta_L' and `Meta-R' keysyms. A second problem is that certain keys
|
|
558 have the Mod2 modifier attached to them for no adequately explored reason.
|
|
559 The correct fix is to pass this file to xmodmap upon starting X:
|
|
560
|
|
561 clear mod2
|
|
562 keysym Multi_key = Alt_L
|
|
563 add mod1 = Alt_L
|
|
564 add mod1 = Alt_R
|
|
565
|
|
566 ** The Compose key on a DEC keyboard does not work as Meta key.
|
|
567
|
|
568 This shell command should fix it:
|
|
569
|
|
570 xmodmap -e 'keycode 0xb1 = Meta_L'
|
|
571
|
|
572 ** When emacs starts up, I get lots of warnings about unknown keysyms.
|
|
573
|
|
574 If you are running the prebuilt binaries, the Motif library expects to find
|
|
575 certain thing in the XKeysymDB file. This file is normally in /usr/lib/X11/
|
|
576 or in /usr/openwin/lib/. If you keep yours in a different place, set the
|
|
577 environment variable $XKEYSYMDB to point to it before starting emacs. If
|
|
578 you still have the problem after doing that, perhaps your version of X is
|
|
579 too old. There is a copy of the MIT X11R5 XKeysymDB file in the emacs `etc'
|
|
580 directory. Try using that one.

582 ** My X resources used to work, and now some of them are being ignored.

584 Check the resources in .../etc/Emacs.ad (which is the same as the file

585 sample.Xdefaults). Perhaps some of the default resources built in to
|
|
586 emacs are now overriding your existing resources. Copy and edit the
|
|
587 resources in Emacs.ad as necessary.

589 ** I get complaints about the mapping of my HP keyboard at startup,
|
|
590 but I haven't changed anything.
|
124
|
591
|
|
592 The default HP keymap is set up to have Mod1 assigned to two different keys:
|
|
593 Meta_L and Mode_switch (even though there is not actually a Mode_switch key on
|
|
594 the keyboard -- it uses an "imaginary" keycode.) There actually is a reason
|
|
595 for this, but it's not a good one. The correct fix is to execute this command
|
|
596 upon starting X:
|
|
597
|
|
598 xmodmap -e 'remove mod1 = Mode_switch'
|

603 The focus issues with a program like XEmacs, which has multiple

607 The R4/R5 version of twm (and all of its descendants) had buggy focus

|
|
609 addition, if you're using twm, make sure you have not specified
|
|
610 "NoTitleFocus" in your .tvtwmrc file. The very nature of this option
|

611 makes twm do some illegal focus tricks, even with the patch.

625 ** Emacs spontaneously displays "I-search: " at the bottom of the screen.
|
0
|
626
|
|
627 This means that Control-S/Control-Q (XON/XOFF) "flow control" is being
|
|
628 used. C-s/C-q flow control is bad for Emacs editors because it takes
|
|
629 away C-s and C-q as user commands. Since editors do not output long
|
|
630 streams of text without user commands, there is no need for a
|
|
631 user-issuable "stop output" command in an editor; therefore, a
|
|
632 properly designed flow control mechanism would transmit all possible
|
|
633 input characters without interference. Designing such a mechanism is
|
|
634 easy, for a person with at least half a brain.
|
|
635
|
|
636 There are three possible reasons why flow control could be taking place:
|
|
637
|
|
638 1) Terminal has not been told to disable flow control
|
|
639 2) Insufficient padding for the terminal in use
|
|
640 3) Some sort of terminal concentrator or line switch is responsible
|
|
641
|
|
642 First of all, many terminals have a set-up mode which controls whether
|
|
643 they generate XON/XOFF flow control characters. This must be set to
|
|
644 "no XON/XOFF" in order for Emacs to work. Sometimes there is an
|
|
645 escape sequence that the computer can send to turn flow control off
|
|
646 and on. If so, perhaps the termcap `ti' string should turn flow
|
|
647 control off, and the `te' string should turn it on.
|
|
648
|
|
649 Once the terminal has been told "no flow control", you may find it
|
|
650 needs more padding. The amount of padding Emacs sends is controlled
|
|
651 by the termcap entry for the terminal in use, and by the output baud
|
|
652 rate as known by the kernel. The shell command `stty' will print
|
|
653 your output baud rate; `stty' with suitable arguments will set it if
|
|
654 it is wrong. Setting to a higher speed causes increased padding. If
|
|
655 the results are wrong for the correct speed, there is probably a
|
|
656 problem in the termcap entry. You must speak to a local Unix wizard
|
|
657 to fix this. Perhaps you are just using the wrong terminal type.
|
|
658
|
|
659 For terminals that lack a "no flow control" mode, sometimes just
|
|
660 giving lots of padding will prevent actual generation of flow control
|
|
661 codes. You might as well try it.
|
|
662
|
|
663 If you are really unlucky, your terminal is connected to the computer
|
|
664 through a concentrator which sends XON/XOFF flow control to the
|
|
665 computer, or it insists on sending flow control itself no matter how
|
|
666 much padding you give it. Unless you can figure out how to turn flow
|
|
667 control off on this concentrator (again, refer to your local wizard),
|
|
668 you are screwed! You should have the terminal or concentrator
|
|
669 replaced with a properly designed one. In the mean time, some drastic
|
|
670 measures can make Emacs semi-work.
|
|
671
|
|
672 You can make Emacs ignore C-s and C-q and let the operating system
|
|
673 handle them. To do this on a per-session basis, just type M-x
|
|
674 enable-flow-control RET. You will see a message that C-\ and C-^ are
|
|
675 now translated to C-s and C-q. (Use the same command M-x
|
|
676 enable-flow-control to turn *off* this special mode. It toggles flow
|
|
677 control handling.)
|
|
678
|
|
679 If C-\ and C-^ are inconvenient for you (for example, if one of them
|
|
680 is the escape character of your terminal concentrator), you can choose
|
|
681 other characters by setting the variables flow-control-c-s-replacement
|
|
682 and flow-control-c-q-replacement. But choose carefully, since all
|
|
683 other control characters are already used by emacs.
|
|
684
|
|
685 IMPORTANT: if you type C-s by accident while flow control is enabled,
|
|
686 Emacs output will freeze, and you will have to remember to type C-q in
|
|
687 order to continue.
|
|
688
|
|
689 If you work in an environment where a majority of terminals of a
|
|
690 certain type are flow control hobbled, you can use the function
|
|
691 `enable-flow-control-on' to turn on this flow control avoidance scheme
|
|
692 automatically. Here is an example:
|
|
693
|
|
694 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")
|
|
695
|
|
696 If this isn't quite correct (e.g. you have a mixture of flow-control hobbled
|
|
697 and good vt200 terminals), you can still run enable-flow-control
|
|
698 manually.
|
|
699
|
|
700 I have no intention of ever redesigning the Emacs command set for the
|
|
701 assumption that terminals use C-s/C-q flow control. XON/XOFF flow
|
|
702 control technique is a bad design, and terminals that need it are bad
|
|
703 merchandise and should not be purchased. Now that X is becoming
|
|
704 widespread, XON/XOFF seems to be on the way out. If you can get some

|
711 For some reason, your system is using brain-damaged C-s/C-q flow
|
|
712 control despite Emacs's attempts to turn it off. Perhaps your
|
|
713 terminal is connected to the computer through a concentrator
|
|
714 that wants to use flow control.
|
|
715
|
|
716 You should first try to tell the concentrator not to use flow control.
|
|
717 If you succeed in this, try making the terminal work without
|
|
718 flow control, as described in the preceding section.
|
|
719
|
|
720 If that line of approach is not successful, map some other characters
|
|
721 into C-s and C-q using keyboard-translate-table. The example above
|
|
722 shows how to do this with C-^ and C-\.

727 Some versions of rlogin (and possibly telnet) do not pass flow
|
|
728 control characters to the remote system to which they connect.
|
|
729 On such systems, emacs on the remote system cannot disable flow
|
|
730 control on the local system.
|
|
731
|
|
732 One way to cure this is to disable flow control on the local host
|
|
733 (the one running rlogin, not the one running rlogind) using the
|
|
734 stty command, before starting the rlogin process. On many systems,
|
120
|
735 `stty start u stop u' will do this.
|
0
|
736
|
|
737 Some versions of tcsh will prevent even this from working. One way
|
|
738 around this is to start another shell before starting rlogin, and
|
|
739 issue the stty command to disable flow control from that shell.
|
|
740
|
|
741 If none of these methods work, the best solution is to type
|
120
|
742 `M-x enable-flow-control' at the beginning of your emacs session, or
|
0
|
743 if you expect the problem to continue, add a line such as the
|
|
744 following to your .emacs (on the host running rlogind):
|
|
745
|
|
746 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")

751 ** TTY redisplay is slow.
|
|
752
|
|
753 XEmacs has fairly new TTY redisplay support (beginning from 19.12),
|
|
754 which doesn't include some basic TTY optimizations -- like using
|
|
755 scrolling regions to move around blocks of text. This is why
|
|
756 redisplay on the traditional terminals, or over slow lines can be very
|
|
757 slow.

|
758

762 ** Screen is updated wrong, but only on one kind of terminal.

763

120
|
764 This could mean that the termcap entry you are using for that terminal

|
|
766 combination of features specified for that terminal.
|
0
|
767
|
|
768 The first step in tracking this down is to record what characters
|
|
769 Emacs is sending to the terminal. Execute the Lisp expression
|
120
|
770 (open-termscript "./emacs-script") to make Emacs write all terminal
|
|
771 output into the file ~/emacs-script as well; then do what makes the
|
|
772 screen update wrong, and look at the file and decode the characters
|
|
773 using the manual for the terminal. There are several possibilities:
|
0
|
774
|
|
775 1) The characters sent are correct, according to the terminal manual.
|
|
776
|
|
777 In this case, there is no obvious bug in Emacs, and most likely you
|
|
778 need more padding, or possibly the terminal manual is wrong.
|
|
779
|
120
|
780 2) The characters sent are incorrect, due to an obscure aspect of the
|
|
781 terminal behavior not described in an obvious way by termcap.
|
0
|
782
|
120
|
783 This case is hard. It will be necessary to think of a way for Emacs
|
|
784 to distinguish between terminals with this kind of behavior and other
|
|
785 terminals that behave subtly differently but are classified the same
|
|
786 by termcap; or else find an algorithm for Emacs to use that avoids the
|
|
787 difference. Such changes must be tested on many kinds of terminals.
|

789 3) The termcap entry is wrong.

|
|
792 needed in commonly used termcap entries for certain terminals.
|
0
|
793
|
120
|
794 4) The characters sent are incorrect, and clearly cannot be right for
|
|
795 any terminal with the termcap entry you were using.
|
0
|
796
|
120

797 This is unambiguously an Emacs bug, and can probably be fixed in
|
197

798 termcap.c, terminfo.c, tparam.c, cm.c, redisplay-tty.c,
|
|
799 redisplay-output.c, or redisplay.c.

863 now explicitly forbidden in ANSI preprocessors, namely substitution

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

124

948 Here is how to fix the configuration. It requires being root.
|
|
949
|
|
950 *** Networked Case
|
|
951
|
|
952 First, make sure the files `/etc/hosts' and `/etc/host.conf' both
|
|
953 exist. The first line in the `/etc/hosts' file should look like this
|
|
954 (replace HOSTNAME with your host name):
|
|
955
|
|
956 127.0.0.1 localhost HOSTNAME
|
|
957
|
|
958 Also make sure that the `/etc/host.conf' files contains the following
|
|
959 lines:
|
|
960
|
|
961 order hosts, bind
|
|
962 multi on
|
|
963
|
|
964 Any changes, permanent and temporary, to the host name should be
|
|
965 indicated in the `/etc/hosts' file, since it acts a limited local
|
|
966 database of addresses and names (e.g., some SLIP connections
|
|
967 dynamically allocate ip addresses).
|
|
968
|
|
969 *** Non-Networked Case
|
|
970
|
|
971 The solution described in the networked case applies here as well.
|
|
972 However, if you never intend to network your machine, you can use a
|
|
973 simpler solution: create an empty `/etc/host.conf' file. The command
|
|
974 `touch /etc/host.conf' suffices to create the file. The `/etc/hosts'
|
|
975 file is not necessary with this approach.
|
|

977 ** On Solaris 2.4, Dired hangs and C-g does not work. Or Emacs hangs

|
124
|
979
|
|
980 casper@fwi.uva.nl says the problem is in X11R6. Rebuild libX11.so
|
|
981 after changing the file xc/config/cf/sunLib.tmpl. Change the lines
|
|
982
|
|
983 #if ThreadedX
|
|
984 #define SharedX11Reqs -lthread
|
|
985 #endif
|
|
986
|
|
987 to:
|
|
988
|
|
989 #if OSMinorVersion < 4
|
|
990 #if ThreadedX
|
|
991 #define SharedX11Reqs -lthread
|
|
992 #endif
|
|
993 #endif
|
|
994
|
|
995 Be sure also to edit x/config/cf/sun.cf so that OSMinorVersion is 4
|
|
996 (as it should be for Solaris 2.4). The file has three definitions for
|
|
997 OSMinorVersion: the first is for x86, the second for SPARC under
|
|
998 Solaris, and the third for SunOS 4. Make sure to update the
|
|
999 definition for your type of machine and system.
|
|
1000
|
|
1001 Then do `make Everything' in the top directory of X11R6, to rebuild
|
|
1002 the makefiles and rebuild X. The X built this way work only on
|
|
1003 Solaris 2.4, not on 2.3.

|
|
1012 #define ThreadedX YES
|
|
1013 to
|
|
1014 #define ThreadedX NO
|
|
1015 in sun.cf and did `make World' to rebuild X11R6. Removing all
|
|
1016 `-DXTHREAD*' flags and `-lthread' entries from lib/X11/Makefile and
|
|
1017 typing 'make install' in that directory also seemed to work.

1053 on the flag to output ^M at the end of each line. You can fix the

1066 This comes from having an invalid X resource, such as
|
|
1067 emacs*Cursor: black
|
|
1068 (which is invalid because it specifies a color name for something
|
|
1069 that isn't a color.)
|
|
1070
|
|
1071 The fix is to correct your X resources.

1073 ** Mail is lost when sent to local aliases.
|
0
|
1074
|
124
|
1075 Many emacs mail user agents (VM and rmail, for instance) use the
|
|
1076 sendmail.el library. This library can arrange for mail to be
|
|
1077 delivered by passing messages to the /usr/lib/sendmail (usually)
|
|
1078 program . In doing so, it passes the '-t' flag to sendmail, which
|
|
1079 means that the name of the recipient of the message is not on the
|
|
1080 command line and, therefore, that sendmail must parse the message to
|
|
1081 obtain the destination address.
|
|
1082
|
|
1083 There is a bug in the SunOS4.1.1 and SunOS4.1.3 versions of sendmail.
|
|
1084 In short, when given the -t flag, the SunOS sendmail won't recognize
|
|
1085 non-local (i.e. NIS) aliases. It has been reported that the Solaris
|
|
1086 2.x versions of sendmail do not have this bug. For those using SunOS
|
|
1087 4.1, the best fix is to install sendmail V8 or IDA sendmail (which
|
|
1088 have other advantages over the regular sendmail as well). At the time
|
|
1089 of this writing, these official versions are available:
|
|
1090
|
|
1091 Sendmail V8 on ftp.cs.berkeley.edu in /ucb/sendmail:
|
|
1092 sendmail.8.6.9.base.tar.Z (the base system source & documentation)
|
|
1093 sendmail.8.6.9.cf.tar.Z (configuration files)
|
|
1094 sendmail.8.6.9.misc.tar.Z (miscellaneous support programs)
|
|
1095 sendmail.8.6.9.xdoc.tar.Z (extended documentation, with postscript)
|
|
1096

1116 ** After running emacs once, subsequent invocations crash.
|
|
1117
|
|
1118 Some versions of SVR4 have a serious bug in the implementation of the
|
|
1119 mmap () system call in the kernel; this causes emacs to run correctly
|
|
1120 the first time, and then crash when run a second time.
|
|
1121
|
|
1122 Contact your vendor and ask for the mmap bug fix; in the mean time,
|
|
1123 you may be able to work around the problem by adding a line to your
|
|
1124 operating system description file (whose name is reported by the
|
|
1125 configure script) that reads:
|
|
1126 #define SYSTEM_MALLOC
|
|
1127 This makes Emacs use memory less efficiently, but seems to work around
|
|
1128 the kernel bug.

1130 ** Inability to send an Alt-modified key, when Emacs is communicating
|
197
|
1131 directly with an X server.
|
0
|
1132
|
124
|
1133 If you have tried to bind an Alt-modified key as a command, and it
|
|
1134 does not work to type the command, the first thing you should check is
|
|
1135 whether the key is getting through to Emacs. To do this, type C-h c
|
|
1136 followed by the Alt-modified key. C-h c should say what kind of event
|
|
1137 it read. If it says it read an Alt-modified key, then make sure you
|
|
1138 have made the key binding correctly.
|
|
1139
|
|
1140 If C-h c reports an event that doesn't have the Alt modifier, it may
|
|
1141 be because your X server has no key for the Alt modifier. The X
|
|
1142 server that comes from MIT does not set up the Alt modifier by
|
|
1143 default.
|
|
1144
|
|
1145 If your keyboard has keys named Alt, you can enable them as follows:
|
0
|
1146
|
124
|
1147 xmodmap -e 'add mod2 = Alt_L'
|
|
1148 xmodmap -e 'add mod2 = Alt_R'
|
|
1149
|
|
1150 If the keyboard has just one key named Alt, then only one of those
|
|
1151 commands is needed. The modifier `mod2' is a reasonable choice if you
|
|
1152 are using an unmodified MIT version of X. Otherwise, choose any
|
|
1153 modifier bit not otherwise used.
|
0
|
1154
|
124
|
1155 If your keyboard does not have keys named Alt, you can use some other
|
|
1156 keys. Use the keysym command in xmodmap to turn a function key (or
|
|
1157 some other 'spare' key) into Alt_L or into Alt_R, and then use the
|
|
1158 commands show above to make them modifier keys.
|
|
1159
|
|
1160 Note that if you have Alt keys but no Meta keys, Emacs translates Alt
|
|
1161 into Meta. This is because of the great importance of Meta in Emacs.

1163 ** `Pid xxx killed due to text modification or page I/O error'

1165 On HP/UX, you can get that error when the Emacs executable is on an NFS

1166 file system. HP/UX responds this way if it tries to swap in a page and
|
|
1167 does not get a response from the server within a timeout whose default
|
|
1168 value is just ten seconds.
|
|
1169

1170 If this happens to you, extend the timeout period.

1172 ** `expand-file-name' fails to work on any but the machine you dumped
|

1173 Emacs on.
|
124
|
1174
|
|
1175 On Ultrix, if you use any of the functions which look up information
|
|
1176 in the passwd database before dumping Emacs (say, by using
|
|
1177 expand-file-name in site-init.el), then those functions will not work
|
|
1178 in the dumped Emacs on any host but the one Emacs was dumped on.
|
|
1179
|
|
1180 The solution? Don't use expand-file-name in site-init.el, or in
|
|
1181 anything it loads. Yuck - some solution.

0
|
1182
|
124
|
1183 I'm not sure why this happens; if you can find out exactly what is
|
|
1184 going on, and perhaps find a fix or a workaround, please let us know.
|
|
1185 Perhaps the YP functions cache some information, the cache is included
|
|
1186 in the dumped Emacs, and is then inaccurate on any other host.

|
1192
|
124
|
1193 This typically happens on Suns and other systems that use shared
|
|
1194 libraries. The cause is that the site has installed a version of the
|
|
1195 shared library which uses a name server--but has not installed a
|
|
1196 similar version of the unshared library which Emacs uses.
|
0
|
1197
|
124
|
1198 The result is that most programs, using the shared library, work with
|
|
1199 the nameserver, but Emacs does not.
|
|
1200
|
|
1201 The fix is to install an unshared library that corresponds to what you
|
|
1202 installed in the shared library, and then relink Emacs.

1204 On SunOS 4.1, simply define HAVE_RES_INIT.
|
|
1205
|
|
1206 If you have already installed the name resolver in the file libresolv.a,
|
|
1207 then you need to compile Emacs to use that library. The easiest way to
|
|
1208 do this is to add to config.h a definition of LIBS_SYSTEM, LIBS_MACHINE
|
|
1209 or LIB_STANDARD which uses -lresolv. Watch out! If you redefine a macro
|
|
1210 that is already in use in your configuration to supply some other libraries,
|
|
1211 be careful not to lose the others.
|
|
1212
|
|
1213 Thus, you could start by adding this to config.h:
|
|
1214
|
|
1215 #define LIBS_SYSTEM -lresolv
|
|
1216
|
|
1217 Then if this gives you an error for redefining a macro, and you see that
|
|
1218 the s- file defines LIBS_SYSTEM as -lfoo -lbar, you could change config.h
|
|
1219 again to say this:
|
|
1220
|
|
1221 #define LIBS_SYSTEM -lresolv -lfoo -lbar

|
1229
|
|
1230 christos@theory.tn.cornell.edu says:
|
|
1231
|
|
1232 The problem is that in your .cshrc you have something that tries to
|
197
|
1233 execute `tty`. If you are not running the shell on a real tty then tty
|
|
1234 will print "not a tty". Csh expects one word in some places, but tty
|
|
1235 is giving it back 3.
|
124
|
1236
|
197
|
1237 The solution is to add a pair of quotes around `tty` to make it a
|
|
1238 single word:
|
0
|
1239
|
124
|
1240 if (`tty` == "/dev/console")
|
|
1241
|
|
1242 should be changed to:
|
|
1243
|
|
1244 if ("`tty`" == "/dev/console")
|
|
1245
|
|
1246 Even better, move things that set up terminal sections out of .cshrc
|
|
1247 and into .login.

1259 It has been claimed that this is caused by a bug in certain very old

88
|
1264
|
197
|
1265 OLWM grabs the help key, and retransmits it to the appropriate client
|
|
1266 using XSendEvent. Allowing emacs to react to synthetic events is a
|
|
1267 security hole, so this is turned off by default. You can enable it by
|
|
1268 setting the variable x-allow-sendevents to t. You can also cause fix
|
|
1269 this by telling OLWM to not grab the help key, with the null binding

1270 "OpenWindows.KeyboardCommand.Help:".

|
88
|
1274
|
124
|
1275 The cause of this is a shell startup file that sets the TERMCAP
|
|
1276 environment variable. The terminal emulator uses that variable to
|
|
1277 provide the information on the special terminal type that Emacs
|
|
1278 emulates.
|
88
|
1279
|
124
|
1280 Rewrite your shell startup file so that it does not change TERMCAP
|
|
1281 in such a case. You could use the following conditional which sets
|
|
1282 it only if it is undefined.
|
|
1283
|
|
1284 if ( ! ${?TERMCAP} ) setenv TERMCAP ~/my-termcap-file
|
|
1285
|
|
1286 Or you could set TERMCAP only when you set TERM--which should not
|
|
1287 happen in a non-login shell.

|
88
|
1296
|
124
|
1297 There are a few incompatible changes in XEmacs, and these are the
|
|
1298 symptoms. Some of the emacs-lisp code you are running needs to be
|
|
1299 updated to be compatible with XEmacs.
|
|
1300
|
|
1301 The code should not treat keymaps as arrays (use `define-key', etc.),
|
|
1302 should not use obsolete variables like `unread-command-char' (use
|
197
|
1303 `unread-command-events'). Many (most) of the new ways of doing things
|
124
|
1304 are compatible in GNU Emacs and XEmacs.
|
88
|
1305
|
197
|
1306 Modern Emacs packages (Gnus, VM, W3, efs, etc) are written to support
|
|
1307 GNU Emacs and XEmacs. We have provided modified versions of several
|
|
1308 popular emacs packages (dired, etc) which are compatible with this
|
|
1309 version of emacs. Check to make sure you have not set your load-path
|
|
1310 so that your private copies of these packages are being found before
|
|
1311 the versions in the lisp directory.
|
124
|
1312
|
|
1313 Make sure that your load-path and your $EMACSLOADPATH environment
|
|
1314 variable are not pointing at an Emacs18 lisp directory. This will
|
|
1315 cripple emacs.

|
|
1322 are: face-font, face-foreground, face-background,
|
|
1323 face-background-pixmap, and face-underline-p. The .elc files

197

1341 =============
|
144
|
1342
|
223
|
1343 ** A reminder: XEmacs/Mule work does not currently receive *any*
|
|
1344 funding, and all work is done by volunteers. If you think you can
|
|
1345 help, please contact the XEmacs maintainers.
|
|
1346
|
|
1347 ** XEmacs/Mule doesn't work on a tty.
|
|
1348
|
|
1349 This is a major problem, which we plan to address in a future release
|
|
1350 of XEmacs. Basically, XEmacs should have primitives to be told
|
|
1351 whether the terminal can handle international output, and which
|
|
1352 locale. Also, it should be able to do approximations of characters to
|
|
1353 the nearest supported by the locale.
|
|
1354
|
197
|
1355 ** Internationalized (Asian) Isearch doesn't work.
|
144
|
1356
|
|
1357 Currently, Isearch doesn't directly support any of the input methods
|
|
1358 that are not XIM based (like egg, canna and quail) (and there are
|
223
|
1359 potential problems with XIM version too...). If you're using egg
|
|
1360 there is a workaround. Hitting <RET> right after C-s to invoke
|
|
1361 Isearch will put Isearch in string mode, where a complete string can
|
|
1362 be typed into the minibuffer and then processed by Isearch afterwards.
|
|
1363 Since egg is now supported in the minibuffer using string mode you can
|
|
1364 now use egg to input your Japanese, Korean or Chinese string, then hit
|
|
1365 return to send that to Isearch and then use standard Isearch commands
|
|
1366 from there.
|
144
|
1367
|
223
|
1368 ** Using egg and mousing around while in 'fence' mode screws up my
|
|
1369 buffer.
|
144
|
1370
|
|
1371 Don't do this. The fence modes of egg and canna are currently very
|
|
1372 modal, and messing with where they expect point to be and what they
|
|
1373 think is the current buffer is just asking for trouble. If you're
|
|
1374 lucky they will realize that something is awry, and simply delete the
|
|
1375 fence, but worst case can trash other buffers too. We've tried to
|
|
1376 protect against this where we can, but there still are many ways to
|
|
1377 shoot yourself in the foot. So just finish what you are typing into
|
|
1378 the fence before reaching for the mouse.
|
223
|
1379
|
|
1380 ** Not all languages in Quail are supported like Devanagari and Indian
|
|
1381 languages, Lao and Tibetan.
|
|
1382
|
|
1383 Quail requires more work and testing. Although it has been ported to
|
|
1384 XEmacs, it works really well for Japanese and for the European
|
|
1385 languages.
|
|
1386
|
|
1387 ** Right-to-left mode is not yet implemented, so languages like
|
|
1388 Arabic, Hebrew and Thai don't work.
|
|
1389
|
|
1390 Getting this right requires more work. It may be implemented in a
|
|
1391 future XEmacs version, but don't hold your breath. If you know
|
|
1392 someone who is ready to implement this, please let us know.
|
|
1393
|
|
1394 ** We need more developers and native language testers. It's extremely
