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:

|
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.
|
|

|

|
|
|
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

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. :-)

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.

102 ** Linking with -rpath on IRIX.
|
|
|

|
|
|
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.

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.

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.
|

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

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.

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.

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.

359 /lib/libc.a(_Q_sub.o): Undefined symbol __Q_get_rp_rd referenced from text segment
|
|
|
360
|
|
|
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.

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:

|
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.

|
|
|
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

405 * Problems with running XEmacs
|
|
197
|
406 ==============================
|
|
124
|
407
|
|
|
408 ** You type Control-H (Backspace) expecting to delete characters.
|
|
|
409
|
|
|
410 Emacs has traditionally used Control-H for help; unfortunately this
|
|
|
411 interferes with its use as Backspace on TTY's. One way to solve this
|
|
|
412 problem is to put this in your .emacs:
|
|
|
413
|
|
197
|
414 (when (eq tty-erase-char ?\C-h)
|
|
|
415 (keyboard-translate ?\C-h ?\C-?)
|
|
|
416 (global-set-key "\M-?" 'help-command))
|
|
124
|
417
|
|
197
|
418 This checks whether the TTY erase char is C-h, and if it is, makes
|
|
|
419 Control-H (Backspace) work sensibly, and moves help to Meta-? (ESC ?).
|
|
124
|
420
|
|
|
421 Note that you can probably also access help using F1.
|
|
|
422
|
|
197
|
423 ** Mail agents (VM, Gnus, rmail) cannot get new mail
|
|
|
424
|
|
|
425 rmail and VM get new mail from /usr/spool/mail/$USER using a program
|
|
|
426 called `movemail'. This program interlocks with /bin/mail using the
|
|
|
427 protocol defined by /bin/mail.
|
|
|
428
|
|
|
429 There are two different protocols in general use. One of them uses
|
|
|
430 the `flock' system call. The other involves creating a lock file;
|
|
|
431 `movemail' must be able to write in /usr/spool/mail in order to do
|
|
|
432 this. You control which one is used by defining, or not defining, the
|
|
|
433 macro MAIL_USE_FLOCK in config.h or the m- or s- file it includes. IF
|
|
|
434 YOU DON'T USE THE FORM OF INTERLOCKING THAT IS NORMAL ON YOUR SYSTEM,
|
|
|
435 YOU CAN LOSE MAIL!
|
|
|
436
|
|
|
437 If your system uses the lock file protocol, and fascist restrictions
|
|
|
438 prevent ordinary users from writing the lock files in /usr/spool/mail,
|
|
|
439 you may need to make `movemail' setgid to a suitable group such as
|
|
|
440 `mail'. To do this, use the following commands (as root) after doing
|
|
|
441 the make install.
|
|
|
442
|
|
|
443 chgrp mail movemail
|
|
|
444 chmod 2755 movemail
|
|
|
445
|
|
|
446 Installation normally copies movemail from the build directory to an
|
|
|
447 installation directory which is usually under /usr/local/lib. The
|
|
|
448 installed copy of movemail is usually in the directory
|
|
|
449 /usr/local/lib/emacs/VERSION/TARGET. You must change the group and
|
|
|
450 mode of the installed copy; changing the group and mode of the build
|
|
|
451 directory copy is ineffective.

453 ** XEmacs crashes on Digital Unix when dealing with large compilation

|
|
|
455
|

|
456 This is a known problem with the regexp code, that uses alloca
|
|
|
457 extensively, and overflows the stack in case of complex regexp
|
|
|
458 matches. As a workaround, you can recompile with REGEX_MALLOC
|
|
|
459 defined.

461 ** On Solaris, C-x doesn't get through to Emacs when you use the console.
|

462
|
|
|
463 This is a Solaris feature (at least on Intel x86 cpus). Type C-r
|
|
|
464 C-r C-t, to toggle whether C-x gets through to Emacs.

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

|

486 have the appropriate size and family. However, emacs can only be
|
|
|
487 clever in this way if you have specified the default font using the
|

488 XLFD (X Logical Font Description) format, which looks like

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

500 versions. All X fonts can be referred to via XLFD-style names, so you
|
|
|
501 should use those forms. See the man pages for X(1), xlsfonts(1), and

504 ** The dumped Emacs crashes when run, trying to write pure data.
|
|
0
|
505
|
|
|
506 Two causes have been seen for such problems.
|
|
|
507
|
|
|
508 1) On a system where getpagesize is not a system call, it is defined
|
|
|
509 as a macro. If the definition (in both unexec.c and malloc.c) is wrong,
|
|
|
510 it can cause problems like this. You might be able to find the correct
|
|
|
511 value in the man page for a.out (5).
|
|
|
512
|
|
|
513 2) Some systems allocate variables declared static among the
|
|
|
514 initialized variables. Emacs makes all initialized variables in most
|
|
|
515 of its files pure after dumping, but the variables declared static and
|
|
|
516 not initialized are not supposed to be pure. On these systems you
|
|
|
517 may need to add "#define static" to the m- or the s- file.
|
|
|
518
|
|
124
|
519 ** Reading and writing files is very very slow.
|
|
0
|
520
|
|
|
521 Try evaluating the form (setq lock-directory nil) and see if that helps.
|
|
|
522 There is a problem with file-locking on some systems (possibly related
|
|
|
523 to NFS) that I don't understand. Please send mail to the address
|
|
|
524 xemacs@xemacs.org if you figure this one out.
|
|
|
525
|
|
124
|
526 ** The Emacs window disappears when you type M-q.
|
|
|
527
|
|
|
528 Some versions of the Open Look window manager interpret M-q as a quit
|
|
|
529 command for whatever window you are typing at. If you want to use
|
|
|
530 Emacs with that window manager, you should try to configure the window
|
|
|
531 manager to use some other command. You can disable the
|
|
|
532 shortcut keys entirely by adding this line to ~/.OWdefaults:
|
|
|
533
|
|
|
534 OpenWindows.WindowMenuAccelerators: False
|
|
|
535
|
|
|
536 ** The `Alt' key doesn't behave as `Meta' when running DECwindows.
|
|
|
537
|
|
|
538 The default DEC keyboard mapping has the Alt keys set up to generate the
|
|
|
539 keysym `Multi_key', which has a meaning to xemacs which is distinct from that
|
|
|
540 of the `Meta_L' and `Meta-R' keysyms. A second problem is that certain keys
|
|
|
541 have the Mod2 modifier attached to them for no adequately explored reason.
|
|
|
542 The correct fix is to pass this file to xmodmap upon starting X:
|
|
|
543
|
|
|
544 clear mod2
|
|
|
545 keysym Multi_key = Alt_L
|
|
|
546 add mod1 = Alt_L
|
|
|
547 add mod1 = Alt_R
|
|
|
548
|
|
|
549 ** The Compose key on a DEC keyboard does not work as Meta key.
|
|
|
550
|
|
|
551 This shell command should fix it:
|
|
|
552
|
|
|
553 xmodmap -e 'keycode 0xb1 = Meta_L'
|
|
|
554
|
|
|
555 ** When emacs starts up, I get lots of warnings about unknown keysyms.
|
|
|
556
|
|
|
557 If you are running the prebuilt binaries, the Motif library expects to find
|
|
|
558 certain thing in the XKeysymDB file. This file is normally in /usr/lib/X11/
|
|
|
559 or in /usr/openwin/lib/. If you keep yours in a different place, set the
|
|
|
560 environment variable $XKEYSYMDB to point to it before starting emacs. If
|
|
|
561 you still have the problem after doing that, perhaps your version of X is
|
|
|
562 too old. There is a copy of the MIT X11R5 XKeysymDB file in the emacs `etc'
|
|
|
563 directory. Try using that one.

|
|

569 emacs are now overriding your existing resources. Copy and edit the

572 ** I get complaints about the mapping of my HP keyboard at startup,
|
|
|
573 but I haven't changed anything.
|
|
124
|
574
|
|
|
575 The default HP keymap is set up to have Mod1 assigned to two different keys:
|
|
|
576 Meta_L and Mode_switch (even though there is not actually a Mode_switch key on
|
|
|
577 the keyboard -- it uses an "imaginary" keycode.) There actually is a reason
|
|
|
578 for this, but it's not a good one. The correct fix is to execute this command
|
|
|
579 upon starting X:
|
|
|
580
|
|
|
581 xmodmap -e 'remove mod1 = Mode_switch'

197

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

588 most window managers don't implement them correctly.

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

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

608 ** Emacs spontaneously displays "I-search: " at the bottom of the screen.

|
609
|
|
|
610 This means that Control-S/Control-Q (XON/XOFF) "flow control" is being
|
|
|
611 used. C-s/C-q flow control is bad for Emacs editors because it takes
|
|
|
612 away C-s and C-q as user commands. Since editors do not output long
|
|
|
613 streams of text without user commands, there is no need for a
|
|
|
614 user-issuable "stop output" command in an editor; therefore, a
|
|
|
615 properly designed flow control mechanism would transmit all possible
|
|
|
616 input characters without interference. Designing such a mechanism is
|
|
|
617 easy, for a person with at least half a brain.
|
|
|
618
|
|
|
619 There are three possible reasons why flow control could be taking place:
|
|
|
620
|
|
|
621 1) Terminal has not been told to disable flow control
|
|
|
622 2) Insufficient padding for the terminal in use
|
|
|
623 3) Some sort of terminal concentrator or line switch is responsible
|
|
|
624
|
|
|
625 First of all, many terminals have a set-up mode which controls whether
|
|
|
626 they generate XON/XOFF flow control characters. This must be set to
|
|
|
627 "no XON/XOFF" in order for Emacs to work. Sometimes there is an
|
|
|
628 escape sequence that the computer can send to turn flow control off
|
|
|
629 and on. If so, perhaps the termcap `ti' string should turn flow
|
|
|
630 control off, and the `te' string should turn it on.
|
|
|
631
|
|
|
632 Once the terminal has been told "no flow control", you may find it
|
|
|
633 needs more padding. The amount of padding Emacs sends is controlled
|
|
|
634 by the termcap entry for the terminal in use, and by the output baud
|
|
|
635 rate as known by the kernel. The shell command `stty' will print
|
|
|
636 your output baud rate; `stty' with suitable arguments will set it if
|
|
|
637 it is wrong. Setting to a higher speed causes increased padding. If
|
|
|
638 the results are wrong for the correct speed, there is probably a
|
|
|
639 problem in the termcap entry. You must speak to a local Unix wizard
|
|
|
640 to fix this. Perhaps you are just using the wrong terminal type.
|
|
|
641
|
|
|
642 For terminals that lack a "no flow control" mode, sometimes just
|
|
|
643 giving lots of padding will prevent actual generation of flow control
|
|
|
644 codes. You might as well try it.
|
|
|
645
|
|
|
646 If you are really unlucky, your terminal is connected to the computer
|
|
|
647 through a concentrator which sends XON/XOFF flow control to the
|
|
|
648 computer, or it insists on sending flow control itself no matter how
|
|
|
649 much padding you give it. Unless you can figure out how to turn flow
|
|
|
650 control off on this concentrator (again, refer to your local wizard),
|
|
|
651 you are screwed! You should have the terminal or concentrator
|
|
|
652 replaced with a properly designed one. In the mean time, some drastic
|
|
|
653 measures can make Emacs semi-work.
|
|
|
654
|
|
|
655 You can make Emacs ignore C-s and C-q and let the operating system
|
|
|
656 handle them. To do this on a per-session basis, just type M-x
|
|
|
657 enable-flow-control RET. You will see a message that C-\ and C-^ are
|
|
|
658 now translated to C-s and C-q. (Use the same command M-x
|
|
|
659 enable-flow-control to turn *off* this special mode. It toggles flow
|
|
|
660 control handling.)
|
|
|
661
|
|
|
662 If C-\ and C-^ are inconvenient for you (for example, if one of them
|
|
|
663 is the escape character of your terminal concentrator), you can choose
|
|
|
664 other characters by setting the variables flow-control-c-s-replacement
|
|
|
665 and flow-control-c-q-replacement. But choose carefully, since all
|
|
|
666 other control characters are already used by emacs.
|
|
|
667
|
|
|
668 IMPORTANT: if you type C-s by accident while flow control is enabled,
|
|
|
669 Emacs output will freeze, and you will have to remember to type C-q in
|
|
|
670 order to continue.
|
|
|
671
|
|
|
672 If you work in an environment where a majority of terminals of a
|
|
|
673 certain type are flow control hobbled, you can use the function
|
|
|
674 `enable-flow-control-on' to turn on this flow control avoidance scheme
|
|
|
675 automatically. Here is an example:
|
|
|
676
|
|
|
677 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")
|
|
|
678
|
|
|
679 If this isn't quite correct (e.g. you have a mixture of flow-control hobbled
|
|
|
680 and good vt200 terminals), you can still run enable-flow-control
|
|
|
681 manually.
|
|
|
682
|
|
|
683 I have no intention of ever redesigning the Emacs command set for the
|
|
|
684 assumption that terminals use C-s/C-q flow control. XON/XOFF flow
|
|
|
685 control technique is a bad design, and terminals that need it are bad
|
|
|
686 merchandise and should not be purchased. Now that X is becoming
|
|
|
687 widespread, XON/XOFF seems to be on the way out. If you can get some
|
|
|
688 use out of GNU Emacs on inferior terminals, more power to you, but I
|
|
|
689 will not make Emacs worse for properly designed systems for the sake
|
|
|
690 of inferior systems.

692 ** Control-S and Control-Q commands are ignored completely.
|
|
0
|
693
|
|
|
694 For some reason, your system is using brain-damaged C-s/C-q flow
|
|
|
695 control despite Emacs's attempts to turn it off. Perhaps your
|
|
|
696 terminal is connected to the computer through a concentrator
|
|
|
697 that wants to use flow control.
|
|
|
698
|
|
|
699 You should first try to tell the concentrator not to use flow control.
|
|
|
700 If you succeed in this, try making the terminal work without
|
|
|
701 flow control, as described in the preceding section.
|
|
|
702
|
|
|
703 If that line of approach is not successful, map some other characters
|
|
|
704 into C-s and C-q using keyboard-translate-table. The example above
|
|
|
705 shows how to do this with C-^ and C-\.

710 Some versions of rlogin (and possibly telnet) do not pass flow
|
|
|
711 control characters to the remote system to which they connect.
|
|
|
712 On such systems, emacs on the remote system cannot disable flow
|
|
|
713 control on the local system.
|
|
|
714
|
|
|
715 One way to cure this is to disable flow control on the local host
|
|
|
716 (the one running rlogin, not the one running rlogind) using the
|
|
|
717 stty command, before starting the rlogin process. On many systems,
|
|
120
|
718 `stty start u stop u' will do this.
|
|
0
|
719
|
|
|
720 Some versions of tcsh will prevent even this from working. One way
|
|
|
721 around this is to start another shell before starting rlogin, and
|
|
|
722 issue the stty command to disable flow control from that shell.
|
|
|
723
|
|
|
724 If none of these methods work, the best solution is to type
|
|
120
|
725 `M-x enable-flow-control' at the beginning of your emacs session, or
|
|
0
|
726 if you expect the problem to continue, add a line such as the
|
|
|
727 following to your .emacs (on the host running rlogind):
|
|
|
728
|
|
|
729 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")

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

|
|
|
749 combination of features specified for that terminal.

750
|
|

751 The first step in tracking this down is to record what characters
|
|
|
752 Emacs is sending to the terminal. Execute the Lisp expression
|
|
120
|
753 (open-termscript "./emacs-script") to make Emacs write all terminal
|
|
|
754 output into the file ~/emacs-script as well; then do what makes the
|
|
|
755 screen update wrong, and look at the file and decode the characters
|
|
|
756 using the manual for the terminal. There are several possibilities:
|
|
0
|
757
|
|
|
758 1) The characters sent are correct, according to the terminal manual.
|
|
|
759
|
|
|
760 In this case, there is no obvious bug in Emacs, and most likely you
|
|
|
761 need more padding, or possibly the terminal manual is wrong.
|
|
|
762
|
|
120
|
763 2) The characters sent are incorrect, due to an obscure aspect of the
|
|
|
764 terminal behavior not described in an obvious way by termcap.
|
|
0
|
765
|
|
120
|
766 This case is hard. It will be necessary to think of a way for Emacs
|
|
|
767 to distinguish between terminals with this kind of behavior and other
|
|
|
768 terminals that behave subtly differently but are classified the same
|
|
|
769 by termcap; or else find an algorithm for Emacs to use that avoids the
|
|
|
770 difference. Such changes must be tested on many kinds of terminals.

0

771

772 3) The termcap entry is wrong.

120

774 See the file etc/TERMS for information on changes that are known to be
|
|
|
775 needed in commonly used termcap entries for certain terminals.
|
|
0
|
776
|
|
120
|
777 4) The characters sent are incorrect, and clearly cannot be right for
|
|
|
778 any terminal with the termcap entry you were using.
|

0
|
779
|
|
120
|
780 This is unambiguously an Emacs bug, and can probably be fixed in

197

781 termcap.c, terminfo.c, tparam.c, cm.c, redisplay-tty.c,
|
|
|
782 redisplay-output.c, or redisplay.c.

|
|
942 lines:

|

|
|
|
944 order hosts, bind
|
|
|
945 multi on
|
|
|
946
|
|
|
947 Any changes, permanent and temporary, to the host name should be
|
|
|
948 indicated in the `/etc/hosts' file, since it acts a limited local
|
|
|
949 database of addresses and names (e.g., some SLIP connections
|
|
|
950 dynamically allocate ip addresses).

952 *** Non-Networked Case
|
|
|
953
|
|
|
954 The solution described in the networked case applies here as well.
|
|
|
955 However, if you never intend to network your machine, you can use a
|
|
|
956 simpler solution: create an empty `/etc/host.conf' file. The command
|
|
|
957 `touch /etc/host.conf' suffices to create the file. The `/etc/hosts'
|
|
|
958 file is not necessary with this approach.

963 casper@fwi.uva.nl says the problem is in X11R6. Rebuild libX11.so
|
|
|
964 after changing the file xc/config/cf/sunLib.tmpl. Change the lines
|
|
|
965
|
|
|
966 #if ThreadedX
|
|
|
967 #define SharedX11Reqs -lthread
|

975 #endif

977
|
|
|
978 Be sure also to edit x/config/cf/sun.cf so that OSMinorVersion is 4
|
|
|
979 (as it should be for Solaris 2.4). The file has three definitions for
|
|
|
980 OSMinorVersion: the first is for x86, the second for SPARC under
|
|
|
981 Solaris, and the third for SunOS 4. Make sure to update the
|
|
|
982 definition for your type of machine and system.
|
|
|
983
|
|
|
984 Then do `make Everything' in the top directory of X11R6, to rebuild

1024 ** Regular expressions matching bugs on SCO systems.
|
|

1025
|

1026 On SCO, there are problems in regexp matching when Emacs is compiled
|
|
|
1027 with the system compiler. The compiler version is "Microsoft C
|
|
|
1028 version 6", SCO 4.2.0h Dev Sys Maintenance Supplement 01/06/93; Quick
|

1029 C Compiler Version 1.00.46 (Beta). The solution is to compile with

1032 ** In Shell mode, you get a ^M at the end of every line.

1034 This happens to people who use tcsh, because it is trying to be too
|
|
|
1035 smart. It sees that the Shell uses terminal type `unknown' and turns
|
|
|
1036 on the flag to output ^M at the end of each line. You can fix the

|
|
1037 problem by adding this to your .cshrc file:

1040 if ($EMACS == "t") then

1049 This comes from having an invalid X resource, such as

|
|
|
1052 that isn't a color.)

1056 ** Mail is lost when sent to local aliases.
|

0
|
1057
|
|
124
|
1058 Many emacs mail user agents (VM and rmail, for instance) use the
|
|
|
1059 sendmail.el library. This library can arrange for mail to be
|
|
|
1060 delivered by passing messages to the /usr/lib/sendmail (usually)
|
|
|
1061 program . In doing so, it passes the '-t' flag to sendmail, which
|
|
|
1062 means that the name of the recipient of the message is not on the
|
|
|
1063 command line and, therefore, that sendmail must parse the message to
|
|
|
1064 obtain the destination address.
|
|
|
1065
|
|
|
1066 There is a bug in the SunOS4.1.1 and SunOS4.1.3 versions of sendmail.
|
|
|
1067 In short, when given the -t flag, the SunOS sendmail won't recognize
|
|
|
1068 non-local (i.e. NIS) aliases. It has been reported that the Solaris
|
|
|
1069 2.x versions of sendmail do not have this bug. For those using SunOS
|
|
|
1070 4.1, the best fix is to install sendmail V8 or IDA sendmail (which
|
|
|
1071 have other advantages over the regular sendmail as well). At the time
|
|
|
1072 of this writing, these official versions are available:
|
|
|
1073
|
|
|
1074 Sendmail V8 on ftp.cs.berkeley.edu in /ucb/sendmail:
|
|
|
1075 sendmail.8.6.9.base.tar.Z (the base system source & documentation)
|
|
|
1076 sendmail.8.6.9.cf.tar.Z (configuration files)

1077 sendmail.8.6.9.misc.tar.Z (miscellaneous support programs)
|
|

1078 sendmail.8.6.9.xdoc.tar.Z (extended documentation, with postscript)

1099 ** After running emacs once, subsequent invocations crash.
|
|
|
1100
|
|
|
1101 Some versions of SVR4 have a serious bug in the implementation of the
|
|
|
1102 mmap () system call in the kernel; this causes emacs to run correctly
|
|
|
1103 the first time, and then crash when run a second time.
|
|
|
1104
|
|
|
1105 Contact your vendor and ask for the mmap bug fix; in the mean time,
|
|
|
1106 you may be able to work around the problem by adding a line to your
|
|
|
1107 operating system description file (whose name is reported by the
|
|
|
1108 configure script) that reads:
|
|
|
1109 #define SYSTEM_MALLOC
|
|
|
1110 This makes Emacs use memory less efficiently, but seems to work around
|
|
|
1111 the kernel bug.

1113 ** Inability to send an Alt-modified key, when Emacs is communicating
|
|
197
|
1114 directly with an X server.
|
|
0
|
1115
|
|
124
|
1116 If you have tried to bind an Alt-modified key as a command, and it
|
|
|
1117 does not work to type the command, the first thing you should check is
|
|
|
1118 whether the key is getting through to Emacs. To do this, type C-h c
|
|
|
1119 followed by the Alt-modified key. C-h c should say what kind of event
|
|
|
1120 it read. If it says it read an Alt-modified key, then make sure you
|
|
|
1121 have made the key binding correctly.
|
|
|
1122
|
|
|
1123 If C-h c reports an event that doesn't have the Alt modifier, it may
|
|
|
1124 be because your X server has no key for the Alt modifier. The X
|
|
|
1125 server that comes from MIT does not set up the Alt modifier by
|
|
|
1126 default.
|
|
|
1127
|
|
|
1128 If your keyboard has keys named Alt, you can enable them as follows:
|
|
0
|
1129
|
|
124
|
1130 xmodmap -e 'add mod2 = Alt_L'
|
|
|
1131 xmodmap -e 'add mod2 = Alt_R'
|
|
|
1132
|
|
|
1133 If the keyboard has just one key named Alt, then only one of those
|
|
|
1134 commands is needed. The modifier `mod2' is a reasonable choice if you
|
|
|
1135 are using an unmodified MIT version of X. Otherwise, choose any
|
|
|
1136 modifier bit not otherwise used.
|
|
0
|
1137
|
|
124
|
1138 If your keyboard does not have keys named Alt, you can use some other
|
|
|
1139 keys. Use the keysym command in xmodmap to turn a function key (or
|
|
|
1140 some other 'spare' key) into Alt_L or into Alt_R, and then use the
|
|
|
1141 commands show above to make them modifier keys.
|
|
|
1142
|
|
|
1143 Note that if you have Alt keys but no Meta keys, Emacs translates Alt
|
|
|
1144 into Meta. This is because of the great importance of Meta in Emacs.

124
|
1148 On HP/UX, you can get that error when the Emacs executable is on an NFS
|
|
|
1149 file system. HP/UX responds this way if it tries to swap in a page and
|
|
|
1150 does not get a response from the server within a timeout whose default
|
|
|
1151 value is just ten seconds.
|
|
|

1158 On Ultrix, if you use any of the functions which look up information

1159 in the passwd database before dumping Emacs (say, by using
|
|
|
1160 expand-file-name in site-init.el), then those functions will not work
|
|
|
1161 in the dumped Emacs on any host but the one Emacs was dumped on.
|
|
|
1162
|
|
|
1163 The solution? Don't use expand-file-name in site-init.el, or in
|
|
|
1164 anything it loads. Yuck - some solution.

1176 This typically happens on Suns and other systems that use shared
|
|
|
1177 libraries. The cause is that the site has installed a version of the
|
|
|
1178 shared library which uses a name server--but has not installed a
|
|
|
1179 similar version of the unshared library which Emacs uses.
|
|
0
|
1180
|
|
124
|
1181 The result is that most programs, using the shared library, work with
|
|
|
1182 the nameserver, but Emacs does not.
|
|
|
1183
|
|
|
1184 The fix is to install an unshared library that corresponds to what you
|
|
|
1185 installed in the shared library, and then relink Emacs.

1188
|
|
|
1189 If you have already installed the name resolver in the file libresolv.a,
|
|
|
1190 then you need to compile Emacs to use that library. The easiest way to
|
|
|
1191 do this is to add to config.h a definition of LIBS_SYSTEM, LIBS_MACHINE
|
|
|
1192 or LIB_STANDARD which uses -lresolv. Watch out! If you redefine a macro
|
|
|
1193 that is already in use in your configuration to supply some other libraries,
|
|
|
1194 be careful not to lose the others.
|
|
|
1195
|
|
|
1196 Thus, you could start by adding this to config.h:
|
|
|
1197
|
|
|
1198 #define LIBS_SYSTEM -lresolv
|
|
|
1199
|
|
|
1200 Then if this gives you an error for redefining a macro, and you see that
|
|
|
1201 the s- file defines LIBS_SYSTEM as -lfoo -lbar, you could change config.h
|
|
|
1202 again to say this:
|
|
|
1203
|
|
|
1204 #define LIBS_SYSTEM -lresolv -lfoo -lbar

|
|
1213 christos@theory.tn.cornell.edu says:
|
|
|
1214
|
|
|
1215 The problem is that in your .cshrc you have something that tries to
|
|
197
|
1216 execute `tty`. If you are not running the shell on a real tty then tty
|
|
|
1217 will print "not a tty". Csh expects one word in some places, but tty
|
|
|
1218 is giving it back 3.
|
|
124
|
1219
|
|
197
|
1220 The solution is to add a pair of quotes around `tty` to make it a
|
|
|
1221 single word:
|
|
0
|
1222
|
|
124
|
1223 if (`tty` == "/dev/console")

1226
|
|
|
1227 if ("`tty`" == "/dev/console")
|
|
|
1228

1255 ** Programs running under terminal emulator do not recognize `emacs'
|
|
197
|
1256 terminal type.
|
|
88
|
1257
|
|
124
|
1258 The cause of this is a shell startup file that sets the TERMCAP
|
|
|
1259 environment variable. The terminal emulator uses that variable to
|
|
|
1260 provide the information on the special terminal type that Emacs
|
|
|
1261 emulates.
|
|
88
|
1262
|
|
124
|
1263 Rewrite your shell startup file so that it does not change TERMCAP
|
|
|
1264 in such a case. You could use the following conditional which sets
|
|
|
1265 it only if it is undefined.
|
|
|
1266
|
|
|
1267 if ( ! ${?TERMCAP} ) setenv TERMCAP ~/my-termcap-file
|
|
|
1268
|
|
|
1269 Or you could set TERMCAP only when you set TERM--which should not
|
|
|
1270 happen in a non-login shell.

1273 * Compatibility problems (with Emacs 18, GNU Emacs, or previous XEmacs/lemacs)
|
|
197
|
1274 ==============================================================================
|
|
88
|
1275
|
|
124
|
1276 ** "Symbol's value as variable is void: unread-command-char".
|
|
197
|
1277 "Wrong type argument: arrayp, #<keymap 143 entries>"
|
|
|
1278 "Wrong type argument: stringp, [#<keypress-event return>]"
|
|
88
|
1279
|
|
124
|
1280 There are a few incompatible changes in XEmacs, and these are the
|
|
|
1281 symptoms. Some of the emacs-lisp code you are running needs to be
|
|
|
1282 updated to be compatible with XEmacs.
|
|
|
1283
|
|
|
1284 The code should not treat keymaps as arrays (use `define-key', etc.),
|
|
|
1285 should not use obsolete variables like `unread-command-char' (use
|
|
197
|
1286 `unread-command-events'). Many (most) of the new ways of doing things
|
|
124
|
1287 are compatible in GNU Emacs and XEmacs.
|
|
88
|
1288
|
|
197
|
1289 Modern Emacs packages (Gnus, VM, W3, efs, etc) are written to support
|
|
|
1290 GNU Emacs and XEmacs. We have provided modified versions of several
|
|
|
1291 popular emacs packages (dired, etc) which are compatible with this
|
|
|
1292 version of emacs. Check to make sure you have not set your load-path
|
|
|
1293 so that your private copies of these packages are being found before
|
|
|
1294 the versions in the lisp directory.
|
|
124
|
1295
|
|
|
1296 Make sure that your load-path and your $EMACSLOADPATH environment
|
|
|
1297 variable are not pointing at an Emacs18 lisp directory. This will
|
|
|
1298 cripple emacs.

1300 ** Some packages that worked before now cause the error
|
|
223
|
1301 Wrong type argument: arrayp, #<face ... >
|
|
124
|
1302
|
|
197
|
1303 Code which uses the `face' accessor functions must be recompiled with
|
|
|
1304 xemacs 19.9 or later. The functions whose callers must be recompiled
|
|
|
1305 are: face-font, face-foreground, face-background,
|
|
|
1306 face-background-pixmap, and face-underline-p. The .elc files
|
|
|
1307 generated by version 19.9 will work in 19.6 and 19.8, but older .elc
|
|
|
1308 files which contain calls to these functions will not work in 19.9.

1310 ** Signaling: (error "Byte code stack underflow (byte compiler bug), pc 38")
|
|
88
|
1311
|
|
120
|
1312 This error is given when XEmacs 20 is compiled without MULE support
|
|
88
|
1313 but is attempting to load a .elc which requires MULE support. The fix
|
|
|
1314 is to rebytecompile the offending file.

|
|

1319 which includes an outdated copy of mail-abbrevs.el. Remove the copy
|

1320 that comes with bbdb and use the one that comes with XEmacs.

1323 * MULE issues
|
|
197
|
1324 =============
|
|
144
|
1325
|
|
223
|
1326 ** A reminder: XEmacs/Mule work does not currently receive *any*
|
|
|
1327 funding, and all work is done by volunteers. If you think you can
|
|
|
1328 help, please contact the XEmacs maintainers.
|
|
|
1329
|
|
|
1330 ** XEmacs/Mule doesn't work on a tty.
|
|
|
1331
|
|
|
1332 This is a major problem, which we plan to address in a future release
|
|
|
1333 of XEmacs. Basically, XEmacs should have primitives to be told
|
|
|
1334 whether the terminal can handle international output, and which
|
|
|
1335 locale. Also, it should be able to do approximations of characters to
|
|
|
1336 the nearest supported by the locale.
|
|
|
1337
|
|
197
|
1338 ** Internationalized (Asian) Isearch doesn't work.
|
|
144
|
1339
|
|
|
1340 Currently, Isearch doesn't directly support any of the input methods
|
|
|
1341 that are not XIM based (like egg, canna and quail) (and there are
|
|
223
|
1342 potential problems with XIM version too...). If you're using egg
|
|
|
1343 there is a workaround. Hitting <RET> right after C-s to invoke
|
|
|
1344 Isearch will put Isearch in string mode, where a complete string can
|
|
|
1345 be typed into the minibuffer and then processed by Isearch afterwards.
|
|
|
1346 Since egg is now supported in the minibuffer using string mode you can
|
|
|
1347 now use egg to input your Japanese, Korean or Chinese string, then hit
|
|
|
1348 return to send that to Isearch and then use standard Isearch commands
|
|
|
1349 from there.
|
|
144
|
1350
|
|
223
|
1351 ** Using egg and mousing around while in 'fence' mode screws up my
|
|
|
1352 buffer.
|
|
144
|
1353
|
|
|
1354 Don't do this. The fence modes of egg and canna are currently very
|
|
|
1355 modal, and messing with where they expect point to be and what they
|
|
|
1356 think is the current buffer is just asking for trouble. If you're
|
|
|
1357 lucky they will realize that something is awry, and simply delete the
|
|
|
1358 fence, but worst case can trash other buffers too. We've tried to
|
|
|
1359 protect against this where we can, but there still are many ways to
|
|
|
1360 shoot yourself in the foot. So just finish what you are typing into
|
|
|
1361 the fence before reaching for the mouse.
|
|
223
|
1362
|
|
|
1363 ** Not all languages in Quail are supported like Devanagari and Indian
|
|
|
1364 languages, Lao and Tibetan.
|
|
|
1365
|
|
|
1366 Quail requires more work and testing. Although it has been ported to
|
|
|
1367 XEmacs, it works really well for Japanese and for the European
|
|
|
1368 languages.
|
|
|
1369
|
|
|
1370 ** Right-to-left mode is not yet implemented, so languages like
|
|
|
1371 Arabic, Hebrew and Thai don't work.
|
|
|
1372
|
|
|
1373 Getting this right requires more work. It may be implemented in a
|
|
|
1374 future XEmacs version, but don't hold your breath. If you know
|
|
|
1375 someone who is ready to implement this, please let us know.
|
|
|
1376
|
|
|
1377 ** We need more developers and native language testers. It's extremely
|
|
|
1378 difficult (and not particularly productive) to address languages that
|
|
|
1379 nobody is using and testing.
|
|
|
1380
|
|
|
1381 ** The kWnn and cWnn support for Chinese and Korean needs developers
|
|
|
1382 and testers. It probably doesn't work.
|
|
|
1383
|
|
|
1384 ** There are no `native XEmacs' TUTORIALs for any Asian languages,
|
|
|
1385 including Japanese. FSF Emacs and XEmacs tutorials are quite similar,
|
|
|
1386 so it should be sufficient to skim through the differences and apply
|
|
|
1387 them to the Japanese version.
|
|
|
1388
|
|
|
1389 ** We only have localized menus translated for Japanese, and the
|
|
|
1390 Japanese menus are developing bitrot (the Mule menu appears in
|
|
|
1391 English).
|
|
|
1392
|
|
|
1393 ** XIM is untested for any language other than Japanese.
