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
|
|
|
16 `C-c C-f' to move to previous equal level. `C-h m' will give more
|
|
|
17 advice 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 Linux without also using
|
|
|
32 `-fno-strength-reduce'.
|
|
|
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
|
|
|
36 later.
|
|
|
37
|
|
|
38 ** Excessive optimization with pgcc can break XEmacs
|
|
|
39
|
|
|
40 It has been reported on some systems that compiling with -O6 can lead
|
|
|
41 to XEmacs failures. The workaround is to use a lower optimization
|
|
|
42 level. -O2 and -O4 have been tested extensively.
|
|
|
43
|
|
197
|
44 All of this depends heavily on the version of pgcc.

49 At least at the b34 level, and the latest-and-greatest IBM xlc
|
|
|
50 (3.1.4.4), there are problems with -O3. I haven't investigated
|
|
|
51 further.

|
|
52
|
|
|
53 ** Sed problems on Solaris 2.5
|
|
|
54
|
|
|
55 There have been reports of Sun sed truncating very lines in the
|
|
|
56 Makefile during configuration. The workaround is to use GNU sed or,
|
|
|
57 even better, think of a better way to generate Makefile, and send us a
|
|
|
58 patch. :-)
|
|
|
59
|

|
60 ** test-distrib says that the distribution has been clobbered
|
|
|
61 or, temacs prints "Command key out of range 0-127"
|
|
|
62 or, temacs runs and dumps xemacs, but xemacs totally fails to work.
|
|
|
63 or, temacs gets errors dumping xemacs
|
|
|
64
|
|
|
65 This can be because the .elc files have been garbled. Do not be
|
|
|
66 fooled by the fact that most of a .elc file is text: these are binary
|
|
|
67 files and can contain all 256 byte values.
|
|
|
68
|
|
|
69 In particular `shar' cannot be used for transmitting GNU Emacs. It
|
|
|
70 typically truncates "lines". (this does not apply to GNU shar, which
|
|
|
71 uses uuencode to encode binary files.)
|
|
|
72
|
|
|
73 If you have a copy of Emacs that has been damaged in its nonprinting
|
|
|
74 characters, you can fix them by running:
|
|
|
75
|
|
|
76 make all-elc
|
|
|
77
|
|
|
78 This will rebuild all the needed .elc files.

80 ** `Error: No ExtNode to pop!' on Linux systems with Lesstif.
|
|
|
81
|
|
|
82 This error message has been observed with lesstif-0.75a. It does not
|
|
|
83 appear to cause any harm.
|
|
|
84
|
|
|
85 ### Does this happen in any of the more recent versions of
|
|
|
86 Lesstif/XEmacs?

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

|
90 Darrell Kindred <dkindred@cmu.edu> writes:
|
|
|
91 There are a couple of problems [with use of -rpath with Irix ld], though:
|
|
|
92
|
|
|
93 1. The ld in IRIX 5.3 ignores all but the last -rpath
|
|
|
94 spec, so the patched configure spits out a warning
|
|
|
95 if --x-libraries or --site-runtime-libraries are
|
|
|
96 specified under irix 5.x, and it only adds -rpath
|
|
|
97 entries for the --site-runtime-libraries. This bug was
|
|
|
98 fixed sometime between 5.3 and 6.2.
|
|
|
99
|
|
|
100 2. IRIX gcc 2.7.2 doesn't accept -rpath directly, so
|
|
|
101 it would have to be prefixed by -Xlinker or "-Wl,".
|
|
|
102 This would be fine, except that configure compiles with
|
|
|
103 ${CC-cc} $CFLAGS $LDFLAGS ...
|
|
|
104 rather than quoting $LDFLAGS with prefix-args, like
|
|
|
105 src/Makefile does. So if you specify --x-libraries
|
|
|
106 or --site-runtime-libraries, you must use --use-gcc=no,
|
|
|
107 or configure will fail.
|
|
|
108
|

109 ### Is this valid in 20.3?

|
111 ** On Irix 5.x and 6.x, the dumped XEmacs (xemacs) core dumps when executed
|
|
197
|
112 on another machine, or after newer SGI IRIX patches have been installed.
|
|
124
|
113
|
|
|
114 The xemacs binary must be executed with the same "libc.so" file which
|
|
|
115 was used when the xemacs binary was dumped. Some SGI IRIX patches
|
|
|
116 update this file. Make sure that all machines using the xemacs binary
|
|
|
117 are using the same set of IRIX patches. If xemacs core dumps after a
|
|
|
118 patch upgrade then you will have to redump it from temacs.
|
|
|
119
|
|
197
|
120 We don't know what causes this tight dependency, but we hope to fix it
|
|
|
121 in the future.
|
|
|
122
|
|
124
|
123 ** xemacs: can't resolve symbol '__malloc_hook'
|
|
|
124
|
|
|
125 This is a Linux problem where you've compiled the XEmacs binary on a libc
|
|
|
126 5.4 with version higher than 5.4.19 and attempted to run the binary against
|
|
|
127 an earlier version. The solution is to upgrade your old library.
|
|
|
128
|
|
|
129 ** Compilation errors on VMS.
|
|
|
130
|
|
|
131 Sorry, XEmacs does not work under VMS. You might consider working on
|
|
|
132 the port if you really want to have XEmacs work under VMS.
|
|
|
133
|
|
197
|
134 ** On Solaris 2 I get undefined symbols from libcurses.a.
|
|
124
|
135
|
|
|
136 You probably have /usr/ucblib/ on your LD_LIBRARY_PATH. Do the link with
|
|
197
|
137 LD_LIBRARY_PATH unset. Generally, avoid using any ucb* stuff when
|
|
|
138 building XEmacs.
|
|
124
|
139
|
|
197
|
140 ** On Solaris 2 I cannot make alloc.o, glyphs.o or process.o.
|
|
124
|
141
|
|
|
142 The SparcWorks C compiler may have difficulty building those modules
|
|
|
143 with optimization level -xO4. Try using only "-fast" optimization
|
|
|
144 for just those modules. (Or use gcc).
|
|
|
145
|
|
|
146 ** On Digital UNIX, the DEC C compiler might have a problem compiling
|
|
197
|
147 some files.
|
|
124
|
148
|
|
|
149 In particular, src/extents.c and src/faces.c might cause the DEC C
|
|
|
150 compiler to abort. When this happens: cd src, compile the files by
|
|
|
151 hand, cd .., and redo the "make" command. When recompiling the files by
|
|
|
152 hand, use the old C compiler for the following versions of Digital UNIX:
|
|
|
153 - V3.n: Remove "-migrate" from the compile command.
|
|
|
154 - V4.n: Add "-oldc" to the compile command.
|
|
|
155
|
|
197
|
156 A related compiler bug has been fixed by the DEC compiler team. The
|
|
|
157 new versions of the compiler should run fine.
|
|
126
|
158
|
|
124
|
159 ** On HPUX, the HP C compiler might have a problem compiling some files
|
|
|
160 with optimization.

164 Had to drop once again to level 2 optimization, at least to
|
|
|
165 compile lstream.c. Otherwise, I get a "variable is void: \if"
|
|
|
166 problem while dumping (this is a problem I already reported
|
|
|
167 with vanilla hpux 10.01 and 9.07, which went away after
|
|
|
168 applying patches for the C compiler). Trouble is I still
|
|
|
169 haven't found the same patch for hpux 10.10, and I don't
|
|
|
170 remember the patch numbers. I think potential XEmacs builders
|
|
|
171 on HP should be warned about this.
|
|
|
172
|
|
197
|
173 ### Fixed in 20.3?
|
|
|
174
|
|
124
|
175 ** I don't have `xmkmf' and `imake' on my HP.
|
|
|
176
|
|
|
177 You can get these standard X tools by anonymous FTP to hpcvaaz.cv.hp.com.
|
|
|
178 Essentially all X programs need these.
|
|
|
179
|
|
|
180 ** Solaris 2.3 /bin/sh coredumps during configuration.
|
|
|
181
|
|
|
182 This only occurs if you have LANG != C. This is a known bug with
|
|
197
|
183 /bin/sh fixed by installing Patch-ID# 101613-01. Or, you can use
|
|
|
184 bash, as a workaround.
|
|
124
|
185
|
|
|
186 ** On Irix 6.0, make tries (and fails) to build a program named unexelfsgi
|
|
|
187
|
|
|
188 A compiler bug inserts spaces into the string "unexelfsgi . o"
|
|
|
189 in src/Makefile. Edit src/Makefile, after configure is run,
|
|
|
190 find that string, and take out the spaces.
|
|
|
191
|
|
|
192 Compiler fixes in Irix 6.0.1 should eliminate this problem.
|
|
|
193
|
|
197
|
194 ### Fixed in 20.3?
|
|
|
195
|
|
124
|
196 ** Native cc on SCO OpenServer 5 is now OK. Icc may still throw you
|
|
197
|
197 a curve. Here is what Robert Lipe <robertl@arnet.com> says:
|
|
124
|
198
|
|
|
199 Unlike XEmacs 19.13, building with the native cc on SCO OpenServer 5
|
|
|
200 now produces a functional binary. I will typically build this
|
|
|
201 configuration for COFF with:
|
|
|
202
|
|
197
|
203 /path_to_xemacs_source/configure --with-gcc=no \
|
|
124
|
204 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
205 --with-xpm --with-xface --with-sound=nas
|
|
|
206
|
|
|
207 This version now supports ELF builds. I highly recommend this to
|
|
|
208 reduce the in-core footprint of XEmacs. This is now how I compile
|
|
|
209 all my test releases. Build it like this:
|
|
|
210
|
|
|
211 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
|
212 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
213 --with-xpm --with-xface --with-sound=nas --dynamic
|
|
|
214
|
|
|
215 The compiler known as icc [ supplied with the OpenServer 5 Development
|
|
|
216 System ] generates a working binary, but it takes forever to generate
|
|
|
217 XEmacs. ICC also whines more about the code than /bin/cc does. I do
|
|
|
218 believe all its whining is legitimate, however. Note that you do
|
|
|
219 have to 'cd src ; make LD=icc' to avoid linker errors.
|
|
|
220
|
|
|
221 The way I handle the build procedure is:
|
|
|
222
|
|
|
223 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
|
224 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
225 --with-xpm --with-xface --with-sound=nas --dynamic --compiler="icc"
|
|
|
226
|
|
|
227 NOTE I have the xpm, xface, and audio libraries and includes in
|
|
|
228 /usr/local/lib, /usr/local/include. If you don't have these,
|
|
|
229 don't include the "--with-*" arguments in any of my examples.
|
|
|
230
|
|
|
231 In previous versions of XEmacs, you had to override the defaults while
|
|
|
232 compiling font-lock.o and extents.o when building with icc. This seems
|
|
|
233 to no longer be true, but I'm including this old information in case it
|
|
|
234 resurfaces. The process I used was:
|
|
|
235
|
|
|
236 make -k
|
|
|
237 [ procure pizza, beer, repeat ]
|
|
|
238 cd src
|
|
|
239 make CC="icc -W0,-mP1COPT_max_tree_size=3000" font-lock.o extents.o
|
|
|
240 make LD=icc
|
|
|
241
|
|
|
242 If you want sound support, get the tls566 supplement from
|
|
|
243 ftp.sco.com:/TLS or any of its mirrors. It works just groovy
|
|
|
244 with XEmacs.
|
|
|
245
|
|
|
246 The M-x manual-entry is known not to work. If you know Lisp and would
|
|
|
247 like help in making it work, e-mail me at <robertl@dgii.com>.
|
|
|
248 (UNCHECKED for 19.15 -- it might work).
|
|
|
249
|
|
|
250 In earlier releases, gnuserv/gnuclient/gnudoit would open a frame
|
|
|
251 just fine, but the client would lock up and the server would
|
|
|
252 terminate when you used C-x # to close the frame. This is now
|
|
|
253 fixed in XEmacs.
|
|
|
254
|
|
|
255 In etc/ there are two files of note. emacskeys.sco and emacsstrs.sco.
|
|
|
256 The comments at the top of emacskeys.sco describe its function, and
|
|
|
257 the emacstrs.sco is a suitable candidate for /usr/lib/keyboard/strings
|
|
|
258 to take advantage of the keyboard map in emacskeys.sco.
|
|
|
259
|
|
197
|
260 ### Is this valid in 20.3?
|
|
|
261
|
|
124
|
262 ** Under some versions of OSF XEmacs runs fine if built without
|
|
197
|
263 optimization but will crash randomly if built with optimization.
|
|
124
|
264
|
|
|
265 Using 'cc -g' is not sufficient to eliminate all optimization. Try
|
|
|
266 'cc -g -O0' instead.
|
|
|
267
|
|
|
268 ** On SunOS, you get linker errors
|
|
|
269 ld: Undefined symbol
|
|
|
270 _get_wmShellWidgetClass
|
|
|
271 _get_applicationShellWidgetClass
|
|
|
272
|
|
|
273 The fix to this is to install patch 100573 for OpenWindows 3.0
|
|
|
274 or link libXmu statically.
|
|
|
275
|
|
|
276 ** On Sunos 4, you get the error ld: Undefined symbol __lib_version.
|
|
|
277
|
|
|
278 This is the result of using cc or gcc with the shared library meant
|
|
|
279 for acc (the Sunpro compiler). Check your LD_LIBRARY_PATH and delete
|
|
|
280 /usr/lang/SC2.0.1 or some similar directory.
|
|
|
281
|
|
|
282 ** On AIX 4.1.2, linker error messages such as
|
|
|
283 ld: 0711-212 SEVERE ERROR: Symbol .__quous, found in the global symbol table
|
|
|
284 of archive /usr/lib/libIM.a, was not defined in archive member shr.o.
|
|
|
285
|
|
|
286 This is a problem in libIM.a. You can work around it by executing
|
|
|
287 these shell commands in the src subdirectory of the directory where
|
|
|
288 you build Emacs:
|
|
|
289
|
|
|
290 cp /usr/lib/libIM.a .
|
|
|
291 chmod 664 libIM.a
|
|
|
292 ranlib libIM.a
|
|
|
293
|
|
|
294 Then change -lIM to ./libIM.a in the command to link temacs (in
|
|
|
295 Makefile).
|
|
|
296
|
|
|
297 ** On Irix 5.2, unexelfsgi.c can't find cmplrs/stsupport.h.
|
|
|
298
|
|
|
299 The file cmplrs/stsupport.h was included in the wrong file set in the
|
|
|
300 Irix 5.2 distribution. You can find it in the optional fileset
|
|
|
301 compiler_dev, or copy it from some other Irix 5.2 system. A kludgy
|
|
|
302 workaround is to change unexelfsgi.c to include sym.h instead of
|
|
|
303 syms.h.
|
|
|
304
|
|
|
305 ** Link failure when using acc on a Sun.
|
|
|
306
|
|
|
307 To use acc, you need additional options just before the libraries, such as
|
|
|
308
|
|
|
309 /usr/lang/SC2.0.1/values-Xt.o -L/usr/lang/SC2.0.1/cg87 -L/usr/lang/SC2.0.1
|
|
|
310
|
|
|
311 and you need to add -lansi just before -lc.
|
|
|
312
|
|
|
313 The precise file names depend on the compiler version, so we
|
|
|
314 cannot easily arrange to supply them.
|
|
|
315
|
|
|
316 ** Link failure on IBM AIX 1.3 ptf 0013.
|
|
|
317
|
|
|
318 There is a real duplicate definition of the function `_slibc_free' in
|

326 ** Undefined symbols when linking on Sunos 4.1.
|

327
|

|
328 If you get the undefined symbols _atowc _wcslen, _iswprint, _iswspace,
|
|
|
329 _iswcntrl, _wcscpy, and _wcsncpy, then you need to add -lXwchar after
|
|
|
330 -lXaw in the command that links temacs.
|
|
|
331
|
|
|
332 This problem seems to arise only when the international language

335 ** src/Makefile and lib-src/Makefile are truncated--most of the file missing.

337 This can happen if configure uses GNU sed version 2.03. That version
|
|
|
338 had a bug. GNU sed version 2.05 works properly.

|
|
|
344
|
|
|
345 This means your system was installed with only the X11 runtime i.d

347 X11Dev... with smit.

|
|
|
359 The problem is in the Sun shared C library, not in GNU ld.

361 The solution is to install Patch-ID# 100267-03 from Sun.

365 Apparently the version of libXmu.so.a that Sun ships is hosed: it's missing
|
|
|
366 some stuff that is in libXmu.a (the static version). Sun has a patch for
|
|
|
367 this, but a workaround is to use the static version of libXmu, by changing
|
|
|
368 the link command from "-lXmu" to "-Bstatic -lXmu -Bdynamic". If you have
|
|
|
369 OpenWindows 3.0, ask Sun for these patches:

379 When using gcc, you get the error message "undefined symbol __main".
|
|
124
|
380
|
|
|
381 This means that you need to link with the gcc library. It may be called
|
|
|
382 "gcc-gnulib" or "libgcc.a"; figure out where it is, and define LIB_GCC in
|
|
|
383 config.h to point to it.
|
|
|
384
|

385 It may also work to use the GCC version of `ld' instead of the standard one.

387 ** When compiling with X11, you get "undefined symbol _XtStrings".

388
|

389 This means that you are trying to link emacs against the X11r4 version of
|

390 libXt.a, but you have compiled either Emacs or the code in the lwlib
|
|
|
391 subdirectory with the X11r5 header files. That doesn't work.

|
392
|

403 * Problems with running XEmacs
|
|
197
|
404 ==============================
|
|
124
|
405
|
|
|
406 ** You type Control-H (Backspace) expecting to delete characters.
|
|
|
407
|
|
|
408 Emacs has traditionally used Control-H for help; unfortunately this
|
|
|
409 interferes with its use as Backspace on TTY's. One way to solve this
|
|
|
410 problem is to put this in your .emacs:
|
|
|
411
|
|
197
|
412 (when (eq tty-erase-char ?\C-h)
|
|
|
413 (keyboard-translate ?\C-h ?\C-?)
|
|
|
414 (global-set-key "\M-?" 'help-command))
|
|
124
|
415
|
|
197
|
416 This checks whether the TTY erase char is C-h, and if it is, makes
|
|
|
417 Control-H (Backspace) work sensibly, and moves help to Meta-? (ESC ?).
|
|
124
|
418
|
|
|
419 Note that you can probably also access help using F1.
|
|
|
420
|
|
197
|
421 ** Mail agents (VM, Gnus, rmail) cannot get new mail
|
|
|
422
|
|
|
423 rmail and VM get new mail from /usr/spool/mail/$USER using a program
|
|
|
424 called `movemail'. This program interlocks with /bin/mail using the
|
|
|
425 protocol defined by /bin/mail.
|
|
|
426
|
|
|
427 There are two different protocols in general use. One of them uses
|
|
|
428 the `flock' system call. The other involves creating a lock file;
|
|
|
429 `movemail' must be able to write in /usr/spool/mail in order to do
|
|
|
430 this. You control which one is used by defining, or not defining, the
|
|
|
431 macro MAIL_USE_FLOCK in config.h or the m- or s- file it includes. IF
|
|
|
432 YOU DON'T USE THE FORM OF INTERLOCKING THAT IS NORMAL ON YOUR SYSTEM,
|
|
|
433 YOU CAN LOSE MAIL!
|
|
|
434
|
|
|
435 If your system uses the lock file protocol, and fascist restrictions
|
|
|
436 prevent ordinary users from writing the lock files in /usr/spool/mail,
|
|
|
437 you may need to make `movemail' setgid to a suitable group such as
|
|
|
438 `mail'. To do this, use the following commands (as root) after doing
|
|
|
439 the make install.
|
|
|
440
|
|
|
441 chgrp mail movemail
|
|
|
442 chmod 2755 movemail
|
|
|
443
|
|
|
444 Installation normally copies movemail from the build directory to an
|
|
|
445 installation directory which is usually under /usr/local/lib. The
|
|
|
446 installed copy of movemail is usually in the directory
|
|
|
447 /usr/local/lib/emacs/VERSION/TARGET. You must change the group and
|
|
|
448 mode of the installed copy; changing the group and mode of the build
|
|
|
449 directory copy is ineffective.

451 ** On Solaris, C-x doesn't get through to Emacs when you use the console.
|
|
|
452
|
|
|
453 This is a Solaris feature (at least on Intel x86 cpus). Type C-r
|
|
|
454 C-r C-t, to toggle whether C-x gets through to Emacs.

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

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

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

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

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

494 ** The dumped Emacs crashes when run, trying to write pure data.

0
|
495
|
|
|
496 Two causes have been seen for such problems.
|
|
|
497
|
|
|
498 1) On a system where getpagesize is not a system call, it is defined
|
|
|
499 as a macro. If the definition (in both unexec.c and malloc.c) is wrong,
|
|
|
500 it can cause problems like this. You might be able to find the correct
|
|
|
501 value in the man page for a.out (5).
|
|
|
502
|
|
|
503 2) Some systems allocate variables declared static among the
|
|
|
504 initialized variables. Emacs makes all initialized variables in most
|
|
|
505 of its files pure after dumping, but the variables declared static and
|
|
|
506 not initialized are not supposed to be pure. On these systems you
|
|
|
507 may need to add "#define static" to the m- or the s- file.
|
|
|
508
|
|
124
|
509 ** Reading and writing files is very very slow.

|
510
|
|
|
511 Try evaluating the form (setq lock-directory nil) and see if that helps.
|
|
|
512 There is a problem with file-locking on some systems (possibly related
|
|
|
513 to NFS) that I don't understand. Please send mail to the address
|
|
|
514 xemacs@xemacs.org if you figure this one out.

124
|
516 ** The Emacs window disappears when you type M-q.
|
|
|
517
|
|
|
518 Some versions of the Open Look window manager interpret M-q as a quit
|
|
|
519 command for whatever window you are typing at. If you want to use
|
|
|
520 Emacs with that window manager, you should try to configure the window
|
|
|
521 manager to use some other command. You can disable the
|
|
|
522 shortcut keys entirely by adding this line to ~/.OWdefaults:
|
|
|
523
|
|
|
524 OpenWindows.WindowMenuAccelerators: False
|
|
|
525
|

|
526 ** The `Alt' key doesn't behave as `Meta' when running DECwindows.
|
|
|
527
|
|
|
528 The default DEC keyboard mapping has the Alt keys set up to generate the
|
|
|
529 keysym `Multi_key', which has a meaning to xemacs which is distinct from that
|
|
|
530 of the `Meta_L' and `Meta-R' keysyms. A second problem is that certain keys
|
|
|
531 have the Mod2 modifier attached to them for no adequately explored reason.
|
|
|
532 The correct fix is to pass this file to xmodmap upon starting X:
|
|
|
533
|
|
|
534 clear mod2
|
|
|
535 keysym Multi_key = Alt_L
|
|
|
536 add mod1 = Alt_L
|
|
|
537 add mod1 = Alt_R
|
|
|
538
|
|
|
539 ** The Compose key on a DEC keyboard does not work as Meta key.
|
|
|
540
|
|
|
541 This shell command should fix it:
|
|
|
542
|
|
|
543 xmodmap -e 'keycode 0xb1 = Meta_L'
|
|
|
544
|
|
|
545 ** When emacs starts up, I get lots of warnings about unknown keysyms.
|
|
|
546
|
|
|
547 If you are running the prebuilt binaries, the Motif library expects to find
|
|
|
548 certain thing in the XKeysymDB file. This file is normally in /usr/lib/X11/
|
|
|
549 or in /usr/openwin/lib/. If you keep yours in a different place, set the
|
|
|
550 environment variable $XKEYSYMDB to point to it before starting emacs. If
|
|
|
551 you still have the problem after doing that, perhaps your version of X is
|
|
|
552 too old. There is a copy of the MIT X11R5 XKeysymDB file in the emacs `etc'
|
|
|
553 directory. Try using that one.

|

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

|
|
|
563 but I haven't changed anything.
|
|
124
|
564
|
|
|
565 The default HP keymap is set up to have Mod1 assigned to two different keys:
|
|
|
566 Meta_L and Mode_switch (even though there is not actually a Mode_switch key on
|
|
|
567 the keyboard -- it uses an "imaginary" keycode.) There actually is a reason
|
|
|
568 for this, but it's not a good one. The correct fix is to execute this command
|
|
|
569 upon starting X:
|
|
|
570
|
|
|
571 xmodmap -e 'remove mod1 = Mode_switch'

197
|
576 The focus issues with a program like XEmacs, which has multiple
|

578 most window managers don't implement them correctly.

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

598 ** Emacs spontaneously displays "I-search: " at the bottom of the screen.
|
|
0
|
599
|
|
|
600 This means that Control-S/Control-Q (XON/XOFF) "flow control" is being
|
|
|
601 used. C-s/C-q flow control is bad for Emacs editors because it takes
|
|
|
602 away C-s and C-q as user commands. Since editors do not output long
|
|
|
603 streams of text without user commands, there is no need for a
|
|
|
604 user-issuable "stop output" command in an editor; therefore, a
|
|
|
605 properly designed flow control mechanism would transmit all possible
|
|
|
606 input characters without interference. Designing such a mechanism is
|
|
|
607 easy, for a person with at least half a brain.
|
|
|
608
|
|
|
609 There are three possible reasons why flow control could be taking place:
|
|
|
610
|
|
|
611 1) Terminal has not been told to disable flow control
|
|
|
612 2) Insufficient padding for the terminal in use
|
|
|
613 3) Some sort of terminal concentrator or line switch is responsible
|
|
|
614
|
|
|
615 First of all, many terminals have a set-up mode which controls whether
|
|
|
616 they generate XON/XOFF flow control characters. This must be set to
|
|
|
617 "no XON/XOFF" in order for Emacs to work. Sometimes there is an
|
|
|
618 escape sequence that the computer can send to turn flow control off
|
|
|
619 and on. If so, perhaps the termcap `ti' string should turn flow
|
|
|
620 control off, and the `te' string should turn it on.
|
|
|
621
|
|
|
622 Once the terminal has been told "no flow control", you may find it
|
|
|
623 needs more padding. The amount of padding Emacs sends is controlled
|
|
|
624 by the termcap entry for the terminal in use, and by the output baud
|
|
|
625 rate as known by the kernel. The shell command `stty' will print
|
|
|
626 your output baud rate; `stty' with suitable arguments will set it if
|
|
|
627 it is wrong. Setting to a higher speed causes increased padding. If
|

|
628 the results are wrong for the correct speed, there is probably a
|
|
|
629 problem in the termcap entry. You must speak to a local Unix wizard
|
|
|
630 to fix this. Perhaps you are just using the wrong terminal type.
|
|
|
631
|
|
|
632 For terminals that lack a "no flow control" mode, sometimes just
|
|
|
633 giving lots of padding will prevent actual generation of flow control
|
|
|
634 codes. You might as well try it.
|
|
|
635
|
|
|
636 If you are really unlucky, your terminal is connected to the computer
|
|
|
637 through a concentrator which sends XON/XOFF flow control to the
|
|
|
638 computer, or it insists on sending flow control itself no matter how
|
|
|
639 much padding you give it. Unless you can figure out how to turn flow
|
|
|
640 control off on this concentrator (again, refer to your local wizard),
|
|
|
641 you are screwed! You should have the terminal or concentrator
|
|
|
642 replaced with a properly designed one. In the mean time, some drastic
|
|
|
643 measures can make Emacs semi-work.
|
|
|
644
|
|
|
645 You can make Emacs ignore C-s and C-q and let the operating system
|
|
|
646 handle them. To do this on a per-session basis, just type M-x
|
|
|
647 enable-flow-control RET. You will see a message that C-\ and C-^ are
|
|
|
648 now translated to C-s and C-q. (Use the same command M-x
|
|
|
649 enable-flow-control to turn *off* this special mode. It toggles flow
|
|
|
650 control handling.)
|
|
|
651
|
|
|
652 If C-\ and C-^ are inconvenient for you (for example, if one of them
|
|
|
653 is the escape character of your terminal concentrator), you can choose
|
|
|
654 other characters by setting the variables flow-control-c-s-replacement
|
|
|
655 and flow-control-c-q-replacement. But choose carefully, since all
|
|
|
656 other control characters are already used by emacs.
|
|
|
657
|
|
|
658 IMPORTANT: if you type C-s by accident while flow control is enabled,
|
|
|
659 Emacs output will freeze, and you will have to remember to type C-q in
|
|
|
660 order to continue.
|
|
|
661
|
|
|
662 If you work in an environment where a majority of terminals of a
|
|
|
663 certain type are flow control hobbled, you can use the function
|
|
|
664 `enable-flow-control-on' to turn on this flow control avoidance scheme
|
|
|
665 automatically. Here is an example:
|
|
|
666
|
|
|
667 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")
|
|
|
668
|
|
|
669 If this isn't quite correct (e.g. you have a mixture of flow-control hobbled
|
|
|
670 and good vt200 terminals), you can still run enable-flow-control
|
|
|
671 manually.
|
|
|
672
|
|
|
673 I have no intention of ever redesigning the Emacs command set for the
|
|
|
674 assumption that terminals use C-s/C-q flow control. XON/XOFF flow
|
|
|
675 control technique is a bad design, and terminals that need it are bad
|
|
|
676 merchandise and should not be purchased. Now that X is becoming
|
|
|
677 widespread, XON/XOFF seems to be on the way out. If you can get some
|
|
|
678 use out of GNU Emacs on inferior terminals, more power to you, but I
|
|
|
679 will not make Emacs worse for properly designed systems for the sake
|
|
|
680 of inferior systems.
|
|
|

|
|

|
682 ** Control-S and Control-Q commands are ignored completely.
|
|
0
|
683
|
|
|
684 For some reason, your system is using brain-damaged C-s/C-q flow
|
|
|
685 control despite Emacs's attempts to turn it off. Perhaps your
|
|
|
686 terminal is connected to the computer through a concentrator
|
|
|
687 that wants to use flow control.
|
|
|
688
|
|
|
689 You should first try to tell the concentrator not to use flow control.
|
|
|
690 If you succeed in this, try making the terminal work without
|
|
|
691 flow control, as described in the preceding section.
|
|
|
692
|
|
|
693 If that line of approach is not successful, map some other characters
|
|
|
694 into C-s and C-q using keyboard-translate-table. The example above
|
|
|
695 shows how to do this with C-^ and C-\.

700 Some versions of rlogin (and possibly telnet) do not pass flow
|
|
|
701 control characters to the remote system to which they connect.
|
|
|
702 On such systems, emacs on the remote system cannot disable flow
|
|
|
703 control on the local system.
|
|
|
704
|
|
|
705 One way to cure this is to disable flow control on the local host
|
|
|
706 (the one running rlogin, not the one running rlogind) using the
|
|
|
707 stty command, before starting the rlogin process. On many systems,
|
|
120
|
708 `stty start u stop u' will do this.
|
|
0
|
709
|
|
|
710 Some versions of tcsh will prevent even this from working. One way
|
|
|
711 around this is to start another shell before starting rlogin, and
|
|
|
712 issue the stty command to disable flow control from that shell.
|
|
|
713
|
|
|
714 If none of these methods work, the best solution is to type
|
|
120
|
715 `M-x enable-flow-control' at the beginning of your emacs session, or
|
|
0
|
716 if you expect the problem to continue, add a line such as the
|
|
|
717 following to your .emacs (on the host running rlogind):
|
|
|
718
|
|
|
719 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")

724 ** TTY redisplay is slow.
|
|
|
725
|
|
|
726 XEmacs has fairly new TTY redisplay support (beginning from 19.12),
|
|
|
727 which doesn't include some basic TTY optimizations -- like using
|
|
|
728 scrolling regions to move around blocks of text. This is why
|
|
|
729 redisplay on the traditional terminals, or over slow lines can be very
|
|
|
730 slow.

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

738 is wrong, or it could mean that Emacs has a bug handing the
|
|
|
739 combination of features specified for that terminal.

0
|
740
|
|
|
741 The first step in tracking this down is to record what characters
|
|
|
742 Emacs is sending to the terminal. Execute the Lisp expression
|
|
120
|
743 (open-termscript "./emacs-script") to make Emacs write all terminal
|
|
|
744 output into the file ~/emacs-script as well; then do what makes the
|
|
|
745 screen update wrong, and look at the file and decode the characters
|
|
|
746 using the manual for the terminal. There are several possibilities:
|
|
0
|
747
|
|
|
748 1) The characters sent are correct, according to the terminal manual.
|
|
|
749
|
|
|
750 In this case, there is no obvious bug in Emacs, and most likely you
|
|
|
751 need more padding, or possibly the terminal manual is wrong.
|
|
|
752
|
|
120
|
753 2) The characters sent are incorrect, due to an obscure aspect of the
|
|
|
754 terminal behavior not described in an obvious way by termcap.
|
|
0
|
755
|
|
120
|
756 This case is hard. It will be necessary to think of a way for Emacs
|
|
|
757 to distinguish between terminals with this kind of behavior and other
|
|
|
758 terminals that behave subtly differently but are classified the same
|
|
|
759 by termcap; or else find an algorithm for Emacs to use that avoids the
|
|
|
760 difference. Such changes must be tested on many kinds of terminals.

0

761

762 3) The termcap entry is wrong.

764 See the file etc/TERMS for information on changes that are known to be
|
|
|
765 needed in commonly used termcap entries for certain terminals.
|
|
0
|
766
|
|
120

767 4) The characters sent are incorrect, and clearly cannot be right for
|
|
|
768 any terminal with the termcap entry you were using.

769

120

770 This is unambiguously an Emacs bug, and can probably be fixed in

|

772 redisplay-output.c, or redisplay.c.

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

833 /usr/include/sun/audioio.h uses the _IOW macro to define the constant

834 AUDIOSETQSIZE. _IOW in turn uses a K&R preprocessor feature that is
|
|
|
835 now explicitly forbidden in ANSI preprocessors, namely substitution
|
|
|
836 inside character constants. All ANSI C compilers must provide a
|
|
|
837 workaround for this problem. Lucid's C compiler is shipped with a new
|

838 set of system include files. If you are using GCC, there is a script

927
|
|
|
928 First, make sure the files `/etc/hosts' and `/etc/host.conf' both
|
|
|
929 exist. The first line in the `/etc/hosts' file should look like this
|
|
|
930 (replace HOSTNAME with your host name):
|
|
|
931
|
|
|
932 127.0.0.1 localhost HOSTNAME
|
|
|
933
|
|
|
934 Also make sure that the `/etc/host.conf' files contains the following
|
|
|
935 lines:
|
|
|
936
|
|
|
937 order hosts, bind
|
|
|
938 multi on
|
|
|
939
|
|
|
940 Any changes, permanent and temporary, to the host name should be
|
|
|
941 indicated in the `/etc/hosts' file, since it acts a limited local
|
|
|
942 database of addresses and names (e.g., some SLIP connections
|
|
|
943 dynamically allocate ip addresses).

945 *** Non-Networked Case
|
|
|
946
|
|
|
947 The solution described in the networked case applies here as well.
|
|
|
948 However, if you never intend to network your machine, you can use a
|
|
|
949 simpler solution: create an empty `/etc/host.conf' file. The command
|
|
|
950 `touch /etc/host.conf' suffices to create the file. The `/etc/hosts'
|
|
|
951 file is not necessary with this approach.
|
|
|
952
|
|
|
953 ** On Solaris 2.4, Dired hangs and C-g does not work. Or Emacs hangs
|
|

|
954 forever waiting for termination of a subprocess that is a zombie.
|
|
124
|
955
|
|
|
956 casper@fwi.uva.nl says the problem is in X11R6. Rebuild libX11.so
|
|
|
957 after changing the file xc/config/cf/sunLib.tmpl. Change the lines
|
|
|
958
|
|
|
959 #if ThreadedX
|
|
|
960 #define SharedX11Reqs -lthread
|
|
|
961 #endif
|
|
|
962
|
|
|
963 to:
|
|
|
964
|
|
|
965 #if OSMinorVersion < 4
|
|
|
966 #if ThreadedX
|
|
|
967 #define SharedX11Reqs -lthread
|
|
|
968 #endif
|
|
|
969 #endif
|
|
|
970
|
|
|
971 Be sure also to edit x/config/cf/sun.cf so that OSMinorVersion is 4
|
|
|
972 (as it should be for Solaris 2.4). The file has three definitions for
|
|
|
973 OSMinorVersion: the first is for x86, the second for SPARC under
|
|
|
974 Solaris, and the third for SunOS 4. Make sure to update the
|
|
|
975 definition for your type of machine and system.
|
|
|
976
|
|
|
977 Then do `make Everything' in the top directory of X11R6, to rebuild
|
|
|
978 the makefiles and rebuild X. The X built this way work only on
|
|
|
979 Solaris 2.4, not on 2.3.
|
|
|
980
|
|
|
981 For multithreaded X to work it necessary to install patch
|
|
|
982 101925-02 to fix problems in header files [2.4]. You need
|
|
|
983 to reinstall gcc or re-run just-fixinc after installing that
|
|
|
984 patch.

|
986 However, Frank Rust <frust@iti.cs.tu-bs.de> used a simpler solution:
|
|
|
987 he changed
|
|
|
988 #define ThreadedX YES
|
|
|
989 to
|
|
|
990 #define ThreadedX NO
|
|
|
991 in sun.cf and did `make World' to rebuild X11R6. Removing all
|
|
|
992 `-DXTHREAD*' flags and `-lthread' entries from lib/X11/Makefile and
|
|
|
993 typing 'make install' in that directory also seemed to work.

997

124

998 This has been traced to communicating with your machine via kermit,

|
999 with C-\ as the kermit escape character. One solution is to use
|
|
|
1000 another escape character in kermit. One user did
|
|
|
1001
|
|
|
1002 set escape-character 17
|
|
|
1003
|
|
|
1004 in his .kermrc file, to make C-q the kermit escape character.

1006 ** The Motif version of Emacs paints the screen a solid color.

|
|

1011
|
|
|
1012 That the resource has this effect indicates a bug in something, but we
|
|
|
1013 do not yet know what. If it is an Emacs bug, we hope someone can
|
|
|
1014 explain what the bug is so we can fix it. In the mean time, removing
|
|
|
1015 the resource prevents the problem.

1017 ** Regular expressions matching bugs on SCO systems.
|
|
|
1018
|
|
|
1019 On SCO, there are problems in regexp matching when Emacs is compiled
|
|
|
1020 with the system compiler. The compiler version is "Microsoft C
|
|
|
1021 version 6", SCO 4.2.0h Dev Sys Maintenance Supplement 01/06/93; Quick
|
|
|
1022 C Compiler Version 1.00.46 (Beta). The solution is to compile with
|
|
|
1023 GCC.

1025 ** In Shell mode, you get a ^M at the end of every line.
|
|
|
1026
|
|
|
1027 This happens to people who use tcsh, because it is trying to be too
|
|
|
1028 smart. It sees that the Shell uses terminal type `unknown' and turns
|
|
|
1029 on the flag to output ^M at the end of each line. You can fix the
|
|
|
1030 problem by adding this to your .cshrc file:
|
|
|
1031
|
|
|
1032 if ($?EMACS) then
|
|
|
1033 if ($EMACS == "t") then
|
|
|
1034 unset edit

1040 parameter attributes) on protocol request 93'.
|
|
|
1041
|
|
|
1042 This comes from having an invalid X resource, such as
|
|
|
1043 emacs*Cursor: black
|
|
|
1044 (which is invalid because it specifies a color name for something
|
|
|
1045 that isn't a color.)
|
|
|
1046
|
|
|
1047 The fix is to correct your X resources.

1049 ** Mail is lost when sent to local aliases.
|
|
0
|
1050
|
|
124
|
1051 Many emacs mail user agents (VM and rmail, for instance) use the
|
|
|
1052 sendmail.el library. This library can arrange for mail to be
|
|
|
1053 delivered by passing messages to the /usr/lib/sendmail (usually)
|
|
|
1054 program . In doing so, it passes the '-t' flag to sendmail, which
|
|
|
1055 means that the name of the recipient of the message is not on the
|
|
|
1056 command line and, therefore, that sendmail must parse the message to
|
|
|
1057 obtain the destination address.
|
|
|
1058
|
|
|
1059 There is a bug in the SunOS4.1.1 and SunOS4.1.3 versions of sendmail.
|
|
|
1060 In short, when given the -t flag, the SunOS sendmail won't recognize
|
|
|
1061 non-local (i.e. NIS) aliases. It has been reported that the Solaris
|
|
|
1062 2.x versions of sendmail do not have this bug. For those using SunOS
|
|
|
1063 4.1, the best fix is to install sendmail V8 or IDA sendmail (which
|
|
|
1064 have other advantages over the regular sendmail as well). At the time
|
|
|
1065 of this writing, these official versions are available:
|
|
|
1066
|
|
|
1067 Sendmail V8 on ftp.cs.berkeley.edu in /ucb/sendmail:
|
|
|
1068 sendmail.8.6.9.base.tar.Z (the base system source & documentation)
|
|
|
1069 sendmail.8.6.9.cf.tar.Z (configuration files)
|
|
|
1070 sendmail.8.6.9.misc.tar.Z (miscellaneous support programs)
|
|
|
1071 sendmail.8.6.9.xdoc.tar.Z (extended documentation, with postscript)
|
|
|
1072
|
|
|
1073 IDA sendmail on vixen.cso.uiuc.edu in /pub:

1089 These can happen when you try to run on AIX 3.2.5 a program that was

|
1092 ** After running emacs once, subsequent invocations crash.
|
|
|
1093
|
|
|
1094 Some versions of SVR4 have a serious bug in the implementation of the
|
|
|
1095 mmap () system call in the kernel; this causes emacs to run correctly
|
|
|
1096 the first time, and then crash when run a second time.
|
|
|
1097
|
|
|
1098 Contact your vendor and ask for the mmap bug fix; in the mean time,
|
|
|
1099 you may be able to work around the problem by adding a line to your
|
|
|
1100 operating system description file (whose name is reported by the
|
|
|
1101 configure script) that reads:
|
|
|
1102 #define SYSTEM_MALLOC
|
|
|
1103 This makes Emacs use memory less efficiently, but seems to work around
|
|
|
1104 the kernel bug.

|
1105
|
|
|
1106 ** Inability to send an Alt-modified key, when Emacs is communicating
|
|
197
|
1107 directly with an X server.
|
|
0
|
1108
|
|
124
|
1109 If you have tried to bind an Alt-modified key as a command, and it
|
|
|
1110 does not work to type the command, the first thing you should check is
|
|
|
1111 whether the key is getting through to Emacs. To do this, type C-h c
|
|
|
1112 followed by the Alt-modified key. C-h c should say what kind of event
|
|
|
1113 it read. If it says it read an Alt-modified key, then make sure you
|
|
|
1114 have made the key binding correctly.
|
|
|
1115
|
|
|
1116 If C-h c reports an event that doesn't have the Alt modifier, it may
|
|
|
1117 be because your X server has no key for the Alt modifier. The X
|
|
|
1118 server that comes from MIT does not set up the Alt modifier by
|
|
|
1119 default.
|
|
|
1120
|
|
|
1121 If your keyboard has keys named Alt, you can enable them as follows:
|
|
0
|
1122
|
|
124
|
1123 xmodmap -e 'add mod2 = Alt_L'
|
|
|
1124 xmodmap -e 'add mod2 = Alt_R'
|
|
|
1125
|
|
|
1126 If the keyboard has just one key named Alt, then only one of those
|
|
|
1127 commands is needed. The modifier `mod2' is a reasonable choice if you
|
|
|
1128 are using an unmodified MIT version of X. Otherwise, choose any
|
|
|
1129 modifier bit not otherwise used.
|
|
0
|
1130
|
|
124
|
1131 If your keyboard does not have keys named Alt, you can use some other
|
|
|
1132 keys. Use the keysym command in xmodmap to turn a function key (or
|
|
|
1133 some other 'spare' key) into Alt_L or into Alt_R, and then use the
|
|
|
1134 commands show above to make them modifier keys.
|
|
|
1135
|
|
|
1136 Note that if you have Alt keys but no Meta keys, Emacs translates Alt
|
|
|
1137 into Meta. This is because of the great importance of Meta in Emacs.

1140
|
|
124
|
1141 On HP/UX, you can get that error when the Emacs executable is on an NFS
|
|
|
1142 file system. HP/UX responds this way if it tries to swap in a page and
|
|
|
1143 does not get a response from the server within a timeout whose default
|
|
|
1144 value is just ten seconds.
|
|
|
1145
|
|
|
1146 If this happens to you, extend the timeout period.

1149 Emacs on.
|
|
124
|
1150
|
|
|
1151 On Ultrix, if you use any of the functions which look up information
|
|
|
1152 in the passwd database before dumping Emacs (say, by using
|
|
|
1153 expand-file-name in site-init.el), then those functions will not work
|
|
|
1154 in the dumped Emacs on any host but the one Emacs was dumped on.
|
|
|
1155
|
|
|
1156 The solution? Don't use expand-file-name in site-init.el, or in
|
|
|
1157 anything it loads. Yuck - some solution.

1159 I'm not sure why this happens; if you can find out exactly what is
|
|

1160 going on, and perhaps find a fix or a workaround, please let us know.
|
|
|
1161 Perhaps the YP functions cache some information, the cache is included
|
|
|
1162 in the dumped Emacs, and is then inaccurate on any other host.

1169 This typically happens on Suns and other systems that use shared
|
|
|
1170 libraries. The cause is that the site has installed a version of the
|
|
|
1171 shared library which uses a name server--but has not installed a
|
|
|
1172 similar version of the unshared library which Emacs uses.
|
|
0
|
1173
|
|
124
|
1174 The result is that most programs, using the shared library, work with
|
|
|
1175 the nameserver, but Emacs does not.
|
|
|
1176
|
|
|
1177 The fix is to install an unshared library that corresponds to what you
|
|
|
1178 installed in the shared library, and then relink Emacs.

1180 On SunOS 4.1, simply define HAVE_RES_INIT.
|
|
|
1181
|
|
|
1182 If you have already installed the name resolver in the file libresolv.a,
|
|
|
1183 then you need to compile Emacs to use that library. The easiest way to
|
|
|
1184 do this is to add to config.h a definition of LIBS_SYSTEM, LIBS_MACHINE
|
|
|
1185 or LIB_STANDARD which uses -lresolv. Watch out! If you redefine a macro
|
|
|
1186 that is already in use in your configuration to supply some other libraries,
|
|
|
1187 be careful not to lose the others.
|
|
|
1188
|
|
|
1189 Thus, you could start by adding this to config.h:
|
|
|
1190
|
|
|
1191 #define LIBS_SYSTEM -lresolv
|
|
|
1192
|
|
|
1193 Then if this gives you an error for redefining a macro, and you see that
|
|
|
1194 the s- file defines LIBS_SYSTEM as -lfoo -lbar, you could change config.h
|
|
|
1195 again to say this:
|
|
|
1196
|
|
|
1197 #define LIBS_SYSTEM -lresolv -lfoo -lbar

|
|
|
1206 christos@theory.tn.cornell.edu says:
|
|
|
1207
|
|
|
1208 The problem is that in your .cshrc you have something that tries to
|
|
197
|
1209 execute `tty`. If you are not running the shell on a real tty then tty
|
|
|
1210 will print "not a tty". Csh expects one word in some places, but tty
|
|
|
1211 is giving it back 3.
|
|
124
|
1212
|
|
197
|
1213 The solution is to add a pair of quotes around `tty` to make it a
|
|
|
1214 single word:
|
|
0
|
1215
|
|
124
|
1216 if (`tty` == "/dev/console")
|

1217

|
|
1219
|
|
|
1220 if ("`tty`" == "/dev/console")
|
|
|
1221
|
|
|
1222 Even better, move things that set up terminal sections out of .cshrc
|
|
|
1223 and into .login.

1243 security hole, so this is turned off by default. You can enable it by
|
|

1244 setting the variable x-allow-sendevents to t. You can also cause fix

1256 Rewrite your shell startup file so that it does not change TERMCAP
|
|
|
1257 in such a case. You could use the following conditional which sets
|
|
|
1258 it only if it is undefined.
|
|
|
1259
|
|
|
1260 if ( ! ${?TERMCAP} ) setenv TERMCAP ~/my-termcap-file
|
|
|
1261
|
|
|
1262 Or you could set TERMCAP only when you set TERM--which should not
|
|
|
1263 happen in a non-login shell.

1266 * Compatibility problems (with Emacs 18, GNU Emacs, or previous XEmacs/lemacs)
|

1267 ==============================================================================

|
1269 ** "Symbol's value as variable is void: unread-command-char".
|
|
197
|
1270 "Wrong type argument: arrayp, #<keymap 143 entries>"
|
|
|
1271 "Wrong type argument: stringp, [#<keypress-event return>]"
|
|
88
|
1272
|
|
124
|
1273 There are a few incompatible changes in XEmacs, and these are the
|
|
|
1274 symptoms. Some of the emacs-lisp code you are running needs to be
|
|
|
1275 updated to be compatible with XEmacs.
|
|
|
1276
|
|
|
1277 The code should not treat keymaps as arrays (use `define-key', etc.),
|
|
|
1278 should not use obsolete variables like `unread-command-char' (use
|
|
197
|
1279 `unread-command-events'). Many (most) of the new ways of doing things
|
|
124
|
1280 are compatible in GNU Emacs and XEmacs.
|
|
88
|
1281
|
|
197
|
1282 Modern Emacs packages (Gnus, VM, W3, efs, etc) are written to support
|
|
|
1283 GNU Emacs and XEmacs. We have provided modified versions of several
|
|
|
1284 popular emacs packages (dired, etc) which are compatible with this
|
|
|
1285 version of emacs. Check to make sure you have not set your load-path
|
|
|
1286 so that your private copies of these packages are being found before
|
|
|
1287 the versions in the lisp directory.
|
|
124
|
1288
|
|
|
1289 Make sure that your load-path and your $EMACSLOADPATH environment
|
|
|
1290 variable are not pointing at an Emacs18 lisp directory. This will
|
|
|
1291 cripple emacs.

1293 ** Some packages that worked before now cause the error
|
|
|
1294 Wrong type argument: arrayp, #<face ... >
|
|
|
1295
|
|
197
|
1296 Code which uses the `face' accessor functions must be recompiled with
|
|
|
1297 xemacs 19.9 or later. The functions whose callers must be recompiled
|
|
|
1298 are: face-font, face-foreground, face-background,
|
|
|
1299 face-background-pixmap, and face-underline-p. The .elc files
|
|
|
1300 generated by version 19.9 will work in 19.6 and 19.8, but older .elc
|
|
|
1301 files which contain calls to these functions will not work in 19.9.

1303 ** Signaling: (error "Byte code stack underflow (byte compiler bug), pc 38")
|
|

|
1304
|
|
120
|
1305 This error is given when XEmacs 20 is compiled without MULE support
|
|
88
|
1306 but is attempting to load a .elc which requires MULE support. The fix
|
|
|
1307 is to rebytecompile the offending file.

1313 that comes with bbdb and use the one that comes with XEmacs.

1316 * MULE issues
|

|
1317 =============
|
|
144
|
1318
|
|
197
|
1319 ** Internationalized (Asian) Isearch doesn't work.
|
|
144
|
1320
|
|
|
1321 Currently, Isearch doesn't directly support any of the input methods
|
|
|
1322 that are not XIM based (like egg, canna and quail) (and there are
|
|
|
1323 potential problems with XIM version too...). This is something
|
|
|
1324 we are working on, but for the moment, if you're using egg there is a
|
|
|
1325 workaround. Hitting <RET> right after C-s to invoke Isearch will put
|
|
|
1326 Isearch in string mode, where a complete string can be typed into the
|
|
|
1327 minibuffer and then processed by Isearch afterwards. Since egg is now
|
|
|
1328 supported in the minibuffer using string mode you can now use egg to
|
|
|
1329 input your Japanese, Korean or Chinese string, then hit return to send
|
|
|
1330 that to Isearch and then use standard Isearch commands from there.
|
|
|
1331
|
|
|
1332 ** Using egg or canna and mousing around while in 'fence' mode screws
|
|
197
|
1333 up my buffer.
|
|
144
|
1334
|
|
|
1335 Don't do this. The fence modes of egg and canna are currently very
|
|
|
1336 modal, and messing with where they expect point to be and what they
|
|
|
1337 think is the current buffer is just asking for trouble. If you're
|
|
|
1338 lucky they will realize that something is awry, and simply delete the
|
|
|
1339 fence, but worst case can trash other buffers too. We've tried to
|
|
|
1340 protect against this where we can, but there still are many ways to
|
|
|
1341 shoot yourself in the foot. So just finish what you are typing into
|
|
|
1342 the fence before reaching for the mouse.
