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

11 - Problems with building XEmacs
|
|
|
12 - Problems with running XEmacs

13 - Compatibility problems

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

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

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

|
|
|
186 further.

189 ** SunOS/Solaris
|
|
|
190 *** Link failure when using acc on a Sun.
|
|
|
191
|
|
|
192 To use acc, you need additional options just before the libraries, such as
|
|
|
193
|
|
|
194 /usr/lang/SC2.0.1/values-Xt.o -L/usr/lang/SC2.0.1/cg87 -L/usr/lang/SC2.0.1
|
|
|
195
|
|
|
196 and you need to add -lansi just before -lc.
|
|
|
197
|
|
|
198 The precise file names depend on the compiler version, so we
|
|
|
199 cannot easily arrange to supply them.
|
|
|
200
|
|
|
201 *** Problems finding X11 libraries on Solaris with Openwindows
|
|
|
202
|
|
|
203 Some users have reported problems in this area. The reported solution
|
|
|
204 is to define the environment variable OPENWINHOME, even if you must set
|
|
|
205 it to `/usr/openwin'.
|
|
|
206
|
|
|
207 *** Sed problems on Solaris 2.5
|
|
|
208
|
|
|
209 There have been reports of Sun sed truncating very lines in the
|
|
|
210 Makefile during configuration. The workaround is to use GNU sed or,
|
|
|
211 even better, think of a better way to generate Makefile, and send us a
|
|
|
212 patch. :-)
|
|
|
213
|
|
|
214 *** On Solaris 2 I get undefined symbols from libcurses.a.
|
|
|
215
|
|
|
216 You probably have /usr/ucblib/ on your LD_LIBRARY_PATH. Do the link with
|
|
|
217 LD_LIBRARY_PATH unset. Generally, avoid using any ucb* stuff when
|
|
|
218 building XEmacs.
|
|
|
219
|
|
|
220 *** On Solaris 2 I cannot make alloc.o, glyphs.o or process.o.
|
|
|
221
|
|
|
222 The SparcWorks C compiler may have difficulty building those modules
|
|
|
223 with optimization level -xO4. Try using only "-fast" optimization
|
|
|
224 for just those modules. (Or use gcc).
|
|
|
225
|
|
|
226 *** Solaris 2.3 /bin/sh coredumps during configuration.
|
|
|
227
|
|
|
228 This only occurs if you have LANG != C. This is a known bug with
|
|
|
229 /bin/sh fixed by installing Patch-ID# 101613-01. Or, you can use
|
|
|
230 bash, as a workaround.
|
|
|
231
|
|
|
232 *** On SunOS, you get linker errors
|
|
|
233 ld: Undefined symbol
|
|
|
234 _get_wmShellWidgetClass
|
|
|
235 _get_applicationShellWidgetClass
|
|
|
236
|
|
|
237 The fix to this is to install patch 100573 for OpenWindows 3.0
|
|
|
238 or link libXmu statically.
|
|
|
239
|
|
|
240 *** On Sunos 4, you get the error ld: Undefined symbol __lib_version.
|
|
|
241
|
|
|
242 This is the result of using cc or gcc with the shared library meant
|
|
|
243 for acc (the Sunpro compiler). Check your LD_LIBRARY_PATH and delete
|
|
|
244 /usr/lang/SC2.0.1 or some similar directory.
|
|
|
245
|
|
|
246 *** Undefined symbols when linking on Sunos 4.1.
|
|
|
247
|
|
|
248 If you get the undefined symbols _atowc _wcslen, _iswprint, _iswspace,
|
|
|
249 _iswcntrl, _wcscpy, and _wcsncpy, then you need to add -lXwchar after
|
|
|
250 -lXaw in the command that links temacs.
|
|
|
251
|
|
|
252 This problem seems to arise only when the international language
|
|
|
253 extensions to X11R5 are installed.
|
|
|
254
|
|
|
255 *** On a Sun running SunOS 4.1.1, you get this error message from GNU ld:
|
|
|
256
|
|
|
257 /lib/libc.a(_Q_sub.o): Undefined symbol __Q_get_rp_rd referenced from text segment
|
|
|
258
|
|
|
259 The problem is in the Sun shared C library, not in GNU ld.
|
|
|
260
|
|
|
261 The solution is to install Patch-ID# 100267-03 from Sun.
|
|
|
262
|
|
|
263 *** SunOS 4.1.2: undefined symbol _get_wmShellWidgetClass
|
|
|
264
|
|
|
265 Apparently the version of libXmu.so.a that Sun ships is hosed: it's missing
|
|
|
266 some stuff that is in libXmu.a (the static version). Sun has a patch for
|
|
|
267 this, but a workaround is to use the static version of libXmu, by changing
|
|
|
268 the link command from "-lXmu" to "-Bstatic -lXmu -Bdynamic". If you have
|
|
|
269 OpenWindows 3.0, ask Sun for these patches:
|
|
|
270 100512-02 4.1.x OpenWindows 3.0 libXt Jumbo patch
|
|
|
271 100573-03 4.1.x OpenWindows 3.0 undefined symbols with shared libXmu
|
|
|
272
|
|
|
273 *** Random other SunOS 4.1.[12] link errors.
|
|
|
274
|
|
|
275 The X headers and libraries that Sun ships in /usr/{include,lib}/X11 are
|
|
|
276 broken. Use the ones in /usr/openwin/{include,lib} instead.
|
|
|
277
|
|
|
278 ** Linux
|
|
|
279 *** Under Linux, you get "too many arguments to function `getpgrp'".
|
|
|
280
|
|
|
281 You have probably installed LessTiff under `/usr/local' and `libXm.so'
|
|
|
282 could not be found when linking `getpgrp()' test program, making XEmacs
|
|
|
283 think that `getpgrp()' takes an argument. Try adding `/usr/local/lib'
|
|
|
284 in `/etc/ld.so.conf' and run `ldconfig'. Then run XEmacs's `configure'
|
|
|
285 again. As with all problems of this type, reading the config.log file
|
|
|
286 generated from configure and seeing the log of how the test failed can
|
|
|
287 prove enlightening.
|
|
|
288
|
|
|
289 *** `Error: No ExtNode to pop!' on Linux systems with Lesstif.
|
|
197
|
290
|
|
|
291 This error message has been observed with lesstif-0.75a. It does not
|
|
|
292 appear to cause any harm.
|
|
|
293
|
|
373
|
294 *** xemacs: can't resolve symbol '__malloc_hook'
|
|
|
295
|
|
|
296 This is a Linux problem where you've compiled the XEmacs binary on a libc
|
|
|
297 5.4 with version higher than 5.4.19 and attempted to run the binary against
|
|
|
298 an earlier version. The solution is to upgrade your old library.

300 ** IRIX
|
|
|
301 *** Linking with -rpath on IRIX.

303 Darrell Kindred <dkindred@cmu.edu> writes:
|
|
|
304 There are a couple of problems [with use of -rpath with Irix ld], though:
|
|
|
305
|
|
|
306 1. The ld in IRIX 5.3 ignores all but the last -rpath
|
|
|
307 spec, so the patched configure spits out a warning
|
|
|
308 if --x-libraries or --site-runtime-libraries are
|
|
|
309 specified under irix 5.x, and it only adds -rpath
|
|
|
310 entries for the --site-runtime-libraries. This bug was
|
|
|
311 fixed sometime between 5.3 and 6.2.
|
|
|
312
|
|
|
313 2. IRIX gcc 2.7.2 doesn't accept -rpath directly, so
|
|
|
314 it would have to be prefixed by -Xlinker or "-Wl,".
|
|
|
315 This would be fine, except that configure compiles with
|
|
|
316 ${CC-cc} $CFLAGS $LDFLAGS ...
|
|
|
317 rather than quoting $LDFLAGS with prefix-args, like
|

318 src/Makefile does. So if you specify --x-libraries
|
|
|
319 or --site-runtime-libraries, you must use --use-gcc=no,

320 or configure will fail.

338 Irix 5.2 distribution. You can find it in the optional fileset
|
|
|
339 compiler_dev, or copy it from some other Irix 5.2 system. A kludgy

|
362 hand, cd .., and redo the "make" command. When recompiling the files by

363 hand, use the old C compiler for the following versions of Digital UNIX:

|
|
364 - V3.n: Remove "-migrate" from the compile command.
|

|
365 - V4.n: Add "-oldc" to the compile command.

447 ** SCO OpenServer
|
|
|
448 *** Native cc on SCO OpenServer 5 is now OK. Icc may still throw you
|
|
197
|
449 a curve. Here is what Robert Lipe <robertl@arnet.com> says:
|
|
124
|
450
|
|
|
451 Unlike XEmacs 19.13, building with the native cc on SCO OpenServer 5
|
|
|
452 now produces a functional binary. I will typically build this
|
|
|
453 configuration for COFF with:
|
|
|
454
|
|
197
|
455 /path_to_xemacs_source/configure --with-gcc=no \
|
|
124
|
456 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
457 --with-xpm --with-xface --with-sound=nas
|
|
|
458
|
|
|
459 This version now supports ELF builds. I highly recommend this to
|
|
|
460 reduce the in-core footprint of XEmacs. This is now how I compile
|
|
|
461 all my test releases. Build it like this:
|
|
|
462
|
|
|
463 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
|
464 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
465 --with-xpm --with-xface --with-sound=nas --dynamic
|
|
|
466
|
|
|
467 The compiler known as icc [ supplied with the OpenServer 5 Development
|
|
|
468 System ] generates a working binary, but it takes forever to generate
|
|
|
469 XEmacs. ICC also whines more about the code than /bin/cc does. I do
|
|
|
470 believe all its whining is legitimate, however. Note that you do
|
|
|
471 have to 'cd src ; make LD=icc' to avoid linker errors.
|
|
|
472
|
|
|
473 The way I handle the build procedure is:
|
|
|
474
|
|
|
475 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
|
476 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
477 --with-xpm --with-xface --with-sound=nas --dynamic --compiler="icc"
|
|
|
478
|
|
|
479 NOTE I have the xpm, xface, and audio libraries and includes in
|
|
|
480 /usr/local/lib, /usr/local/include. If you don't have these,
|
|
|
481 don't include the "--with-*" arguments in any of my examples.
|
|
|
482
|
|
|
483 In previous versions of XEmacs, you had to override the defaults while
|
|
|
484 compiling font-lock.o and extents.o when building with icc. This seems
|
|
|
485 to no longer be true, but I'm including this old information in case it
|
|
|
486 resurfaces. The process I used was:
|
|
|
487
|
|
|
488 make -k
|
|
|
489 [ procure pizza, beer, repeat ]
|
|
|
490 cd src
|
|
|
491 make CC="icc -W0,-mP1COPT_max_tree_size=3000" font-lock.o extents.o
|
|
|
492 make LD=icc
|
|
|
493
|
|
|
494 If you want sound support, get the tls566 supplement from
|
|
|
495 ftp.sco.com:/TLS or any of its mirrors. It works just groovy
|
|
|
496 with XEmacs.
|
|
|
497
|
|
|
498 The M-x manual-entry is known not to work. If you know Lisp and would
|
|
|
499 like help in making it work, e-mail me at <robertl@dgii.com>.
|
|
|
500 (UNCHECKED for 19.15 -- it might work).
|
|
|
501
|
|
|
502 In earlier releases, gnuserv/gnuclient/gnudoit would open a frame
|
|
|
503 just fine, but the client would lock up and the server would
|
|
|
504 terminate when you used C-x # to close the frame. This is now
|
|
|
505 fixed in XEmacs.
|
|
|
506
|
|
|
507 In etc/ there are two files of note. emacskeys.sco and emacsstrs.sco.
|
|
|
508 The comments at the top of emacskeys.sco describe its function, and
|
|
|
509 the emacstrs.sco is a suitable candidate for /usr/lib/keyboard/strings
|
|
|
510 to take advantage of the keyboard map in emacskeys.sco.
|
|
|
511
|
|
373
|
512 Note: Much of the above entry is probably not valid for XEmacs 21.0
|
|
207
|
513 and later.

515 ** Cygwin
|
|
|
516 *** In general use etc/check_cygwin_setup.sh to trap environment problems.
|
|
|
517
|
|
|
518 The script etc/check_cygwin_setup.sh will attempt to detect whether
|
|
|
519 you have a suitable environment for building. This script may not work
|
|
|
520 correctly if you are using ash instead of bash (see below).
|
|
|
521
|
|
|
522 *** X11 not detected.
|
|
|
523
|
|
|
524 This is usually because xmkmf is not in your path or because you are
|
|
|
525 using the default cygwin shell. The default cygwin shell (/bin/sh.exe)
|
|
442
|
526 is ash which appears to work in most circumstances but has some weird
|
|
392
|
527 failure modes. I recommend replacing sh.exe with bash.exe, this will
|
|
|
528 mean configure is slower but more reliable.
|
|
|
529
|
|
|
530 *** Subprocesses do not work.
|
|
|
531
|
|
|
532 You do not have "tty" in your CYGWIN32 (for b19) or CYGWIN (for b20)
|
|
|
533 environment variable. This must be set in your autoexec.bat (win95) or
|
|
|
534 the system properties (winnt) as it must be read before the cygwin dll
|
|
|
535 initializes.
|
|
|
536
|
|
|
537 *** ^G does not work on hung subprocesses.
|
|
|
538
|
|
|
539 This is a known problem. It can be remedied with cygwin b20 or greater
|
|
|
540 by defining BROKEN_SIGIO in src/s/cygwin32.h, however this currently
|
|
|
541 leads to instability in XEmacs.
|
|
|
542
|
|
|
543 *** The XEmacs executable crashes at startup.
|
|
|
544
|
|
|
545 This can be caused by many things.
|
|
|
546
|
|
|
547 If you are running with X11 you need to have cygwin b19 or cygwin
|
|
|
548 b20.1 or greater, cygwin b20 will not work.
|
|
|
549
|
|
|
550 If you are running with cygwin b19 make sure you are using egcs 1.0.2
|
|
|
551 rather than vanilla gcc. XEmacs builds by default with -O3 which does
|
|
|
552 not work with the gcc that ships with b19. Alternatively use -O2.
|
|
|
553
|
|
|
554 *** The info files will not build.
|
|
|
555
|
|
|
556 makeinfo that ships with cygwin (all versions) is a noop. You need to
|
|
|
557 obtain makeinfo from somewhere or build it yourself.
|
|
|
558
|
|
|
559 *** I have no graphics.
|
|
|
560
|
|
|
561 You need to obtain the various graphics libraries. Pre-built versions
|
|
|
562 of these and the X libraries are located on the XEmacs website in
|
|
|
563 ftp://ftp.xemacs.org/pub/aux/cygwin*.
|
|
|
564
|
|
|
565 *** There are no images in the toolbar buttons.
|
|
|
566
|
|
|
567 You need version 4.71 of commctrl.dll which does not ship with windows
|
|
|
568 95. You can get this by installing IE 4.0 or downloading it from the

572 * Problems with running XEmacs
|
|
|
573 ==============================
|
|
|
574 ** General
|
|
|
575 *** C-z just refreshes the screen instead of suspending Emacs.
|
|
124
|
576
|
|
|
577 You are probably using a shell that doesn't support job control, even
|
|
197
|
578 though the system itself is capable of it. Try using a different
|
|
|
579 shell.
|
|
124
|
580
|
|
373
|
581 *** You type Control-H (Backspace) expecting to delete characters.
|
|
124
|
582
|
|
|
583 Emacs has traditionally used Control-H for help; unfortunately this
|
|
424
|
584 interferes with its use as Backspace on TTY's. As of XEmacs 21,
|
|
|
585 XEmacs looks at the "erase" setting of TTY structures and maps C-h to
|
|
|
586 backspace when erase is set to C-h. This is sort of a special hack,
|
|
|
587 but it makes it possible for you to use the standard:
|
|
|
588
|
|
|
589 stty erase ^H
|
|
355
|
590
|
|
424
|
591 to get your backspace key to erase characters. The erase setting is
|
|
|
592 recorded in the Lisp variable `tty-erase-char', which you can use to
|
|
|
593 tune the settings in your .emacs.
|
|
124
|
594
|
|
424
|
595 A major drawback of this is that when C-h becomes backspace, it no
|
|
|
596 longer invokes help. In that case, you need to use f1 for help, or
|
|
|
597 bind another key. An example of the latter is the following code,
|
|
|
598 which moves help to Meta-? (ESC ?):
|
|
124
|
599
|
|
424
|
600 (global-set-key "\M-?" 'help-command)
|
|
124
|
601
|
|
373
|
602 *** Mail agents (VM, Gnus, rmail) cannot get new mail
|
|
197
|
603
|
|
|
604 rmail and VM get new mail from /usr/spool/mail/$USER using a program
|
|
|
605 called `movemail'. This program interlocks with /bin/mail using the
|
|
|
606 protocol defined by /bin/mail.
|
|
|
607
|
|
|
608 There are two different protocols in general use. One of them uses
|
|
|
609 the `flock' system call. The other involves creating a lock file;
|
|
|
610 `movemail' must be able to write in /usr/spool/mail in order to do
|
|
|
611 this. You control which one is used by defining, or not defining, the
|
|
|
612 macro MAIL_USE_FLOCK in config.h or the m- or s- file it includes. IF
|
|
|
613 YOU DON'T USE THE FORM OF INTERLOCKING THAT IS NORMAL ON YOUR SYSTEM,
|
|
|
614 YOU CAN LOSE MAIL!
|
|
|
615
|
|
|
616 If your system uses the lock file protocol, and fascist restrictions
|
|
|
617 prevent ordinary users from writing the lock files in /usr/spool/mail,
|
|
|
618 you may need to make `movemail' setgid to a suitable group such as
|
|
|
619 `mail'. To do this, use the following commands (as root) after doing
|
|
|
620 the make install.
|
|
|
621
|
|
|
622 chgrp mail movemail
|
|
|
623 chmod 2755 movemail
|
|
|

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

0
|
671
|
|
|
672 Two causes have been seen for such problems.
|
|
|
673
|
|
|
674 1) On a system where getpagesize is not a system call, it is defined
|
|
|
675 as a macro. If the definition (in both unexec.c and malloc.c) is wrong,
|
|
|
676 it can cause problems like this. You might be able to find the correct
|
|
|
677 value in the man page for a.out (5).
|
|
|
678
|
|
|
679 2) Some systems allocate variables declared static among the
|
|
|
680 initialized variables. Emacs makes all initialized variables in most
|
|
|
681 of its files pure after dumping, but the variables declared static and
|
|
|
682 not initialized are not supposed to be pure. On these systems you
|
|
|
683 may need to add "#define static" to the m- or the s- file.

|

687 Try evaluating the form (setq lock-directory nil) and see if that helps.
|
|
|
688 There is a problem with file-locking on some systems (possibly related
|
|
|
689 to NFS) that I don't understand. Please send mail to the address
|
|

692 *** When emacs starts up, I get lots of warnings about unknown keysyms.
|
|
124
|
693
|
|
|
694 If you are running the prebuilt binaries, the Motif library expects to find
|
|
|
695 certain thing in the XKeysymDB file. This file is normally in /usr/lib/X11/
|
|
|
696 or in /usr/openwin/lib/. If you keep yours in a different place, set the
|
|
|
697 environment variable $XKEYSYMDB to point to it before starting emacs. If
|
|
|
698 you still have the problem after doing that, perhaps your version of X is
|
|
|
699 too old. There is a copy of the MIT X11R5 XKeysymDB file in the emacs `etc'
|
|
|
700 directory. Try using that one.

|

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

714 most window managers don't implement them correctly.

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

717 handling. Sufficiently recent versions of tvtwm have been fixed. In
|
|
|
718 addition, if you're using twm, make sure you have not specified
|
|
|
719 "NoTitleFocus" in your .tvtwmrc file. The very nature of this option
|
|
|
720 makes twm do some illegal focus tricks, even with the patch.

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

|
0
|
735
|
|
|
736 This means that Control-S/Control-Q (XON/XOFF) "flow control" is being
|
|
|
737 used. C-s/C-q flow control is bad for Emacs editors because it takes
|
|
|
738 away C-s and C-q as user commands. Since editors do not output long
|
|
|
739 streams of text without user commands, there is no need for a
|
|
|
740 user-issuable "stop output" command in an editor; therefore, a
|
|
|
741 properly designed flow control mechanism would transmit all possible
|
|
|
742 input characters without interference. Designing such a mechanism is
|
|
|
743 easy, for a person with at least half a brain.
|
|
|
744
|
|
|
745 There are three possible reasons why flow control could be taking place:
|
|
|
746
|
|
|
747 1) Terminal has not been told to disable flow control
|
|
|
748 2) Insufficient padding for the terminal in use
|
|
|
749 3) Some sort of terminal concentrator or line switch is responsible
|
|
|
750
|
|
|
751 First of all, many terminals have a set-up mode which controls whether
|
|
|
752 they generate XON/XOFF flow control characters. This must be set to
|
|
|
753 "no XON/XOFF" in order for Emacs to work. Sometimes there is an
|
|
|
754 escape sequence that the computer can send to turn flow control off
|
|
|
755 and on. If so, perhaps the termcap `ti' string should turn flow
|
|
|
756 control off, and the `te' string should turn it on.
|
|
|
757
|
|
|
758 Once the terminal has been told "no flow control", you may find it
|
|
|
759 needs more padding. The amount of padding Emacs sends is controlled
|
|
|
760 by the termcap entry for the terminal in use, and by the output baud
|
|
|
761 rate as known by the kernel. The shell command `stty' will print
|
|
|
762 your output baud rate; `stty' with suitable arguments will set it if
|
|
|
763 it is wrong. Setting to a higher speed causes increased padding. If
|
|
|
764 the results are wrong for the correct speed, there is probably a
|
|
|
765 problem in the termcap entry. You must speak to a local Unix wizard
|
|
|
766 to fix this. Perhaps you are just using the wrong terminal type.
|
|
|
767
|
|
|
768 For terminals that lack a "no flow control" mode, sometimes just
|
|
|
769 giving lots of padding will prevent actual generation of flow control
|
|
|
770 codes. You might as well try it.
|
|
|
771
|
|
|
772 If you are really unlucky, your terminal is connected to the computer
|
|
|
773 through a concentrator which sends XON/XOFF flow control to the
|
|
|
774 computer, or it insists on sending flow control itself no matter how
|
|
|
775 much padding you give it. Unless you can figure out how to turn flow
|
|
|
776 control off on this concentrator (again, refer to your local wizard),
|
|
|
777 you are screwed! You should have the terminal or concentrator
|
|
|
778 replaced with a properly designed one. In the mean time, some drastic
|
|
|
779 measures can make Emacs semi-work.
|
|
|
780
|
|
|
781 You can make Emacs ignore C-s and C-q and let the operating system
|
|
|
782 handle them. To do this on a per-session basis, just type M-x
|
|
|
783 enable-flow-control RET. You will see a message that C-\ and C-^ are
|
|
|
784 now translated to C-s and C-q. (Use the same command M-x
|
|
|
785 enable-flow-control to turn *off* this special mode. It toggles flow
|
|
|
786 control handling.)
|
|
|
787
|
|
|
788 If C-\ and C-^ are inconvenient for you (for example, if one of them
|
|
|
789 is the escape character of your terminal concentrator), you can choose
|
|
|
790 other characters by setting the variables flow-control-c-s-replacement
|
|
|
791 and flow-control-c-q-replacement. But choose carefully, since all
|
|
|
792 other control characters are already used by emacs.
|
|
|
793
|
|
|
794 IMPORTANT: if you type C-s by accident while flow control is enabled,
|
|
|
795 Emacs output will freeze, and you will have to remember to type C-q in
|
|
|
796 order to continue.
|
|
|
797
|
|
|
798 If you work in an environment where a majority of terminals of a
|
|
|
799 certain type are flow control hobbled, you can use the function
|
|
|
800 `enable-flow-control-on' to turn on this flow control avoidance scheme
|
|
|
801 automatically. Here is an example:
|
|
|
802
|
|
|
803 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")
|
|
|
804
|
|
|
805 If this isn't quite correct (e.g. you have a mixture of flow-control hobbled
|
|
|
806 and good vt200 terminals), you can still run enable-flow-control
|
|
|
807 manually.
|
|
|
808
|
|
|
809 I have no intention of ever redesigning the Emacs command set for the
|
|
|
810 assumption that terminals use C-s/C-q flow control. XON/XOFF flow
|
|
|
811 control technique is a bad design, and terminals that need it are bad
|
|
|
812 merchandise and should not be purchased. Now that X is becoming
|
|
|
813 widespread, XON/XOFF seems to be on the way out. If you can get some
|
|
|
814 use out of GNU Emacs on inferior terminals, more power to you, but I
|
|
|
815 will not make Emacs worse for properly designed systems for the sake
|
|
|
816 of inferior systems.

818 *** Control-S and Control-Q commands are ignored completely.
|
|
0
|
819
|
|
|
820 For some reason, your system is using brain-damaged C-s/C-q flow
|
|
|
821 control despite Emacs's attempts to turn it off. Perhaps your
|
|
|
822 terminal is connected to the computer through a concentrator
|
|
|
823 that wants to use flow control.
|
|
|
824
|
|
|
825 You should first try to tell the concentrator not to use flow control.
|
|
|
826 If you succeed in this, try making the terminal work without
|
|
|
827 flow control, as described in the preceding section.
|
|
|
828
|
|
|
829 If that line of approach is not successful, map some other characters
|
|
|
830 into C-s and C-q using keyboard-translate-table. The example above
|
|
|
831 shows how to do this with C-^ and C-\.

836 Some versions of rlogin (and possibly telnet) do not pass flow
|
|
|
837 control characters to the remote system to which they connect.
|
|
|
838 On such systems, emacs on the remote system cannot disable flow
|
|
|
839 control on the local system.
|
|
|
840
|
|
|
841 One way to cure this is to disable flow control on the local host
|
|
|
842 (the one running rlogin, not the one running rlogind) using the
|
|
|
843 stty command, before starting the rlogin process. On many systems,
|
|
120
|
844 `stty start u stop u' will do this.
|
|
0
|
845
|
|
|
846 Some versions of tcsh will prevent even this from working. One way
|
|
|
847 around this is to start another shell before starting rlogin, and
|
|
|
848 issue the stty command to disable flow control from that shell.
|
|
|
849
|
|
|
850 If none of these methods work, the best solution is to type
|
|
120
|
851 `M-x enable-flow-control' at the beginning of your emacs session, or
|
|
0
|
852 if you expect the problem to continue, add a line such as the
|
|
|
853 following to your .emacs (on the host running rlogind):
|
|

854
|
|
|
855 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")

|
|
197
|
861
|
|
|
862 XEmacs has fairly new TTY redisplay support (beginning from 19.12),
|
|
|
863 which doesn't include some basic TTY optimizations -- like using
|
|
|
864 scrolling regions to move around blocks of text. This is why
|
|
|
865 redisplay on the traditional terminals, or over slow lines can be very
|
|
|
866 slow.

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

875 combination of features specified for that terminal.

0
|
876
|
|

877 The first step in tracking this down is to record what characters
|
|
|
878 Emacs is sending to the terminal. Execute the Lisp expression
|
|
120
|
879 (open-termscript "./emacs-script") to make Emacs write all terminal
|
|
|
880 output into the file ~/emacs-script as well; then do what makes the
|
|
|
881 screen update wrong, and look at the file and decode the characters
|
|
|
882 using the manual for the terminal. There are several possibilities:
|
|
0
|
883
|
|
|
884 1) The characters sent are correct, according to the terminal manual.
|
|
|
885
|
|
|
886 In this case, there is no obvious bug in Emacs, and most likely you
|
|
|
887 need more padding, or possibly the terminal manual is wrong.
|
|
|
888
|
|
120
|
889 2) The characters sent are incorrect, due to an obscure aspect of the
|
|
|
890 terminal behavior not described in an obvious way by termcap.
|
|
0
|
891
|
|
120
|
892 This case is hard. It will be necessary to think of a way for Emacs
|
|
|
893 to distinguish between terminals with this kind of behavior and other
|
|
|
894 terminals that behave subtly differently but are classified the same
|
|
|
895 by termcap; or else find an algorithm for Emacs to use that avoids the
|
|
|
896 difference. Such changes must be tested on many kinds of terminals.

934 *** The Motif version of Emacs paints the screen a solid color.
|
|
|
935
|

|
936 This has been observed to result from the following X resource:
|
|
|
937
|
|
|
938 Emacs*default.attributeFont: -*-courier-medium-r-*-*-*-140-*-*-*-*-iso8859-*
|
|
|
939
|
|
|
940 That the resource has this effect indicates a bug in something, but we
|
|
|
941 do not yet know what. If it is an Emacs bug, we hope someone can
|
|
|
942 explain what the bug is so we can fix it. In the mean time, removing
|
|
|
943 the resource prevents the problem.
|
|
|
944
|
|
|
945 *** After running emacs once, subsequent invocations crash.
|
|
|
946
|
|
|
947 Some versions of SVR4 have a serious bug in the implementation of the
|
|
|
948 mmap () system call in the kernel; this causes emacs to run correctly
|
|
|
949 the first time, and then crash when run a second time.
|
|
|
950
|
|
|
951 Contact your vendor and ask for the mmap bug fix; in the mean time,
|
|
|
952 you may be able to work around the problem by adding a line to your
|
|
|
953 operating system description file (whose name is reported by the
|
|
|
954 configure script) that reads:
|
|
|
955 #define SYSTEM_MALLOC
|
|
|
956 This makes Emacs use memory less efficiently, but seems to work around
|
|
|
957 the kernel bug.

|
959 *** Inability to send an Alt-modified key, when Emacs is communicating
|
|
|
960 directly with an X server.
|
|
|
961
|
|
|
962 If you have tried to bind an Alt-modified key as a command, and it
|
|
|
963 does not work to type the command, the first thing you should check is
|
|
|
964 whether the key is getting through to Emacs. To do this, type C-h c
|
|
|
965 followed by the Alt-modified key. C-h c should say what kind of event
|
|
|
966 it read. If it says it read an Alt-modified key, then make sure you
|
|
|
967 have made the key binding correctly.
|
|
|
968
|
|
|
969 If C-h c reports an event that doesn't have the Alt modifier, it may
|
|
|
970 be because your X server has no key for the Alt modifier. The X
|
|
|
971 server that comes from MIT does not set up the Alt modifier by
|
|
|
972 default.
|
|
|
973
|
|
|
974 If your keyboard has keys named Alt, you can enable them as follows:
|
|
|
975
|
|
|
976 xmodmap -e 'add mod2 = Alt_L'
|
|
|
977 xmodmap -e 'add mod2 = Alt_R'
|
|
|
978
|
|
|
979 If the keyboard has just one key named Alt, then only one of those
|
|
|
980 commands is needed. The modifier `mod2' is a reasonable choice if you
|
|
|
981 are using an unmodified MIT version of X. Otherwise, choose any
|
|
|
982 modifier bit not otherwise used.
|
|
|
983
|
|
|
984 If your keyboard does not have keys named Alt, you can use some other
|
|
|
985 keys. Use the keysym command in xmodmap to turn a function key (or
|
|
|
986 some other 'spare' key) into Alt_L or into Alt_R, and then use the
|
|
|
987 commands show above to make them modifier keys.
|
|
|
988
|
|
|
989 Note that if you have Alt keys but no Meta keys, Emacs translates Alt
|
|
|
990 into Meta. This is because of the great importance of Meta in Emacs.
|
|
|
991
|
|
|
992 *** In Shell mode, you get a ^M at the end of every line.
|
|
|
993
|
|
|
994 This happens to people who use tcsh, because it is trying to be too
|
|
|
995 smart. It sees that the Shell uses terminal type `unknown' and turns
|
|
|
996 on the flag to output ^M at the end of each line. You can fix the
|
|
|
997 problem by adding this to your .cshrc file:
|
|
|
998
|
|
|
999 if ($?EMACS) then
|
|
|
1000 if ($EMACS == "t") then
|
|
|
1001 unset edit
|
|
|
1002 stty -icrnl -onlcr -echo susp ^Z

1008

1009 This comes from having an invalid X resource, such as
|
|
|
1010 emacs*Cursor: black
|
|
|
1011 (which is invalid because it specifies a color name for something

|

1012 that isn't a color.)

1016 *** Once you pull down a menu from the menubar, it won't go away.
|
|
|
1017
|
|
|
1018 It has been claimed that this is caused by a bug in certain very old
|
|
|
1019 (1990?) versions of the twm window manager. It doesn't happen with
|
|
|
1020 recent vintages, or with other window managers.

1022 *** Emacs ignores the "help" key when running OLWM.
|
|
|
1023
|
|
|
1024 OLWM grabs the help key, and retransmits it to the appropriate client
|
|
|
1025 using XSendEvent. Allowing emacs to react to synthetic events is a
|
|
|
1026 security hole, so this is turned off by default. You can enable it by
|
|
|
1027 setting the variable x-allow-sendevents to t. You can also cause fix
|
|
|
1028 this by telling OLWM to not grab the help key, with the null binding
|
|
|
1029 "OpenWindows.KeyboardCommand.Help:".

1031 *** Programs running under terminal emulator do not recognize `emacs'
|
|
|
1032 terminal type.
|
|
|
1033
|
|
|
1034 The cause of this is a shell startup file that sets the TERMCAP
|
|
|
1035 environment variable. The terminal emulator uses that variable to
|
|
|
1036 provide the information on the special terminal type that Emacs
|
|
|
1037 emulates.
|
|
|
1038
|
|
|
1039 Rewrite your shell startup file so that it does not change TERMCAP
|
|
|
1040 in such a case. You could use the following conditional which sets
|
|
|
1041 it only if it is undefined.
|
|
|
1042
|
|
|
1043 if ( ! ${?TERMCAP} ) setenv TERMCAP ~/my-termcap-file
|
|
|
1044
|
|
|
1045 Or you could set TERMCAP only when you set TERM--which should not
|
|
|
1046 happen in a non-login shell.

1114 you have probably compiled using an ANSI C compiler, but with non-ANSI
|
|
|
1115 include files. In particular, on Suns, the file
|
|
|
1116 /usr/include/sun/audioio.h uses the _IOW macro to define the constant
|
|
|
1117 AUDIOSETQSIZE. _IOW in turn uses a K&R preprocessor feature that is
|
|
|
1118 now explicitly forbidden in ANSI preprocessors, namely substitution
|
|
|
1119 inside character constants. All ANSI C compilers must provide a
|
|
|
1120 workaround for this problem. Lucid's C compiler is shipped with a new
|
|
|
1121 set of system include files. If you are using GCC, there is a script
|
|
|
1122 called fixincludes that creates new versions of some system include
|
|
|
1123 files that use this obsolete feature.

|
|
|
1158 Be sure also to edit x/config/cf/sun.cf so that OSMinorVersion is 4
|
|
|
1159 (as it should be for Solaris 2.4). The file has three definitions for
|
|
|
1160 OSMinorVersion: the first is for x86, the second for SPARC under

1162 definition for your type of machine and system.

|
1163
|
|
|
1164 Then do `make Everything' in the top directory of X11R6, to rebuild

|

0
|
1190
|
|
124
|
1191 Many emacs mail user agents (VM and rmail, for instance) use the
|
|
|
1192 sendmail.el library. This library can arrange for mail to be
|
|
|
1193 delivered by passing messages to the /usr/lib/sendmail (usually)
|
|
|
1194 program . In doing so, it passes the '-t' flag to sendmail, which
|
|
|
1195 means that the name of the recipient of the message is not on the
|
|
|
1196 command line and, therefore, that sendmail must parse the message to
|
|
|
1197 obtain the destination address.
|
|
|
1198
|
|
|
1199 There is a bug in the SunOS4.1.1 and SunOS4.1.3 versions of sendmail.
|
|
|
1200 In short, when given the -t flag, the SunOS sendmail won't recognize
|
|
|
1201 non-local (i.e. NIS) aliases. It has been reported that the Solaris
|
|
|
1202 2.x versions of sendmail do not have this bug. For those using SunOS
|
|
|
1203 4.1, the best fix is to install sendmail V8 or IDA sendmail (which
|
|
|
1204 have other advantages over the regular sendmail as well). At the time
|
|
|
1205 of this writing, these official versions are available:
|
|
|
1206
|
|
|
1207 Sendmail V8 on ftp.cs.berkeley.edu in /ucb/sendmail:

|
1221 This typically happens on Suns and other systems that use shared
|
|
|
1222 libraries. The cause is that the site has installed a version of the
|
|
|
1223 shared library which uses a name server--but has not installed a
|
|
|
1224 similar version of the unshared library which Emacs uses.
|

|
1225
|
|
124

1226 The result is that most programs, using the shared library, work with
|
|
|
1227 the nameserver, but Emacs does not.
|
|
|
1228
|
|
|
1229 The fix is to install an unshared library that corresponds to what you

1230 installed in the shared library, and then relink Emacs.

1234 If you have already installed the name resolver in the file libresolv.a,
|
|
|
1235 then you need to compile Emacs to use that library. The easiest way to
|
|
|
1236 do this is to add to config.h a definition of LIBS_SYSTEM, LIBS_MACHINE
|
|
|
1237 or LIB_STANDARD which uses -lresolv. Watch out! If you redefine a macro
|
|
|
1238 that is already in use in your configuration to supply some other libraries,

1241 Thus, you could start by adding this to config.h:
|
|
|
1242
|
|
|
1243 #define LIBS_SYSTEM -lresolv
|
|
|
1244
|
|
|
1245 Then if this gives you an error for redefining a macro, and you see that
|
|
|
1246 the s- file defines LIBS_SYSTEM as -lfoo -lbar, you could change config.h
|
|
|
1247 again to say this:
|
|
|
1248
|
|
|
1249 #define LIBS_SYSTEM -lresolv -lfoo -lbar

|
|
|
1254 On SunOS systems, this problem has been seen to be a result of an

|
|
1255 incomplete installation of gcc 2.2 which allowed some non-ANSI
|
|
|
1256 compatible include files into the compilation. In particular this

|

1257 affected virtually all ioctl() calls.

1261 *** You get crashes in a non-C locale with Linux GNU Libc 2.0.
|
|
|
1262
|
|
|
1263 Internationalization was not the top priority for GNU Libc 2.0.
|
|
|
1264 As of this writing (1998-12-28) you may get crashes while running
|
|
|
1265 XEmacs in a non-C locale. For example, `LC_ALL=en_US xemacs' crashes
|
|
|
1266 while `LC_ALL=C xemacs' runs fine. This happens for example with GNU
|
|
|
1267 libc 2.0.7. Installing libintl.a and libintl.h built from gettext
|
|
|
1268 0.10.35 and re-building XEmacs solves the crashes. Presumably soon
|
|
|
1269 everyone will upgrade to GNU Libc 2.1 and this problem will go away.

1273 If you build with `gpm' support on Linux, you cannot suspend XEmacs
|
|
|
1274 because gpm installs a buggy SIGTSTP handler. Either compile with
|
|
|
1275 `--with-gpm=no', or don't suspend XEmacs on the Linux console until
|
|
|
1276 this bug is fixed.

|
1281 One user on a Linux system reported that this problem went away with
|
|
|
1282 installation of a new X server. The failing server was XFree86 3.1.1.

1285 *** Slow startup on Linux.
|
|
|
1286
|
|
|
1287 People using systems based on the Linux kernel sometimes report that
|
|
|
1288 startup takes 10 to 15 seconds longer than `usual'.
|
|
|
1289
|
|
|
1290 This is because Emacs looks up the host name when it starts.
|
|
|
1291 Normally, this takes negligible time; the extra delay is due to
|
|
|
1292 improper system configuration. This problem can occur for both
|
|
|
1293 networked and non-networked machines.
|
|
|
1294
|
|
|
1295 Here is how to fix the configuration. It requires being root.
|
|
|
1296
|
|
|
1297 **** Networked Case
|
|
|
1298
|
|
|
1299 First, make sure the files `/etc/hosts' and `/etc/host.conf' both
|
|
|
1300 exist. The first line in the `/etc/hosts' file should look like this
|
|
|
1301 (replace HOSTNAME with your host name):
|
|
|
1302
|
|
|
1303 127.0.0.1 localhost HOSTNAME
|
|
|
1304
|
|
|
1305 Also make sure that the `/etc/host.conf' files contains the following
|
|
|
1306 lines:
|
|
|
1307
|
|
|
1308 order hosts, bind
|
|
|
1309 multi on
|
|
|
1310
|
|
|
1311 Any changes, permanent and temporary, to the host name should be
|
|
|
1312 indicated in the `/etc/hosts' file, since it acts a limited local
|
|
|
1313 database of addresses and names (e.g., some SLIP connections
|
|
|
1314 dynamically allocate ip addresses).
|
|
|
1315
|
|
|
1316 **** Non-Networked Case
|
|
|
1317
|
|
|
1318 The solution described in the networked case applies here as well.
|
|
|
1319 However, if you never intend to network your machine, you can use a
|
|
|
1320 simpler solution: create an empty `/etc/host.conf' file. The command
|
|
|
1321 `touch /etc/host.conf' suffices to create the file. The `/etc/hosts'
|
|
|
1322 file is not necessary with this approach.
|
|
|
1323
|
|
|
1324
|
|
|
1325 ** IRIX
|
|
|
1326 *** On Irix, I don't see the toolbar icons and I'm getting lots of
|
|
|
1327 entries in the warnings buffer.
|
|
|
1328
|
|
|
1329 SGI ships a really old Xpm library in /usr/lib which does not work at
|
|
|
1330 all well with XEmacs. The solution is to install your own copy of the
|
|
|
1331 latest version of Xpm somewhere and then use the --site-includes and
|
|
|
1332 --site-libraries flags to tell configure where to find it.
|
|
|
1333
|
|
|
1334 *** Trouble using ptys on IRIX, or running out of ptys.
|
|
|
1335
|
|
|
1336 The program mkpts (which may be in `/usr/adm' or `/usr/sbin') needs to
|
|
|
1337 be set-UID to root, or non-root programs like Emacs will not be able
|
|
|
1338 to allocate ptys reliably.
|
|
|
1339
|
|
|
1340 *** Motif dialog boxes lose on Irix.

|
|
|
1359 with large compilation buffers.
|
|
|
1360
|
|
|
1361 The default stack size under Digital Unix is rather small (2M as
|
|
|
1362 opposed to Solaris 8M), hosing the regexp code, which uses alloca()
|
|
|
1363 extensively, overflowing the stack when complex regexps are used.
|
|
|
1364 Workarounds:
|
|
312
|
1365
|
|
373
|
1366 1) Increase your stack size, using `ulimit -s 8192' or a (t)csh
|
|
|
1367 equivalent;
|
|
|
1368
|
|
|
1369 2) Recompile regex.c with REGEX_MALLOC defined.

1371 *** The `Alt' key doesn't behave as `Meta' when running DECwindows.
|
|
|
1372
|
|
|
1373 The default DEC keyboard mapping has the Alt keys set up to generate the
|
|
|
1374 keysym `Multi_key', which has a meaning to xemacs which is distinct from that
|
|
|
1375 of the `Meta_L' and `Meta-R' keysyms. A second problem is that certain keys
|
|
|
1376 have the Mod2 modifier attached to them for no adequately explored reason.
|
|
|
1377 The correct fix is to pass this file to xmodmap upon starting X:
|
|
|
1378
|
|
|
1379 clear mod2
|
|
|
1380 keysym Multi_key = Alt_L
|
|
|
1381 add mod1 = Alt_L
|
|
|
1382 add mod1 = Alt_R

|
|
1384 *** The Compose key on a DEC keyboard does not work as Meta key.

1390 *** `expand-file-name' fails to work on any but the machine you dumped
|
|
|
1391 Emacs on.
|
|
|
1392
|
|
|
1393 On Ultrix, if you use any of the functions which look up information
|
|
|
1394 in the passwd database before dumping Emacs (say, by using
|
|
|
1395 expand-file-name in site-init.el), then those functions will not work
|
|
|
1396 in the dumped Emacs on any host but the one Emacs was dumped on.
|
|
|
1397
|
|
|
1398 The solution? Don't use expand-file-name in site-init.el, or in
|
|
|
1399 anything it loads. Yuck - some solution.
|
|
|
1400
|
|
|
1401 I'm not sure why this happens; if you can find out exactly what is
|
|
|
1402 going on, and perhaps find a fix or a workaround, please let us know.
|
|
|
1403 Perhaps the YP functions cache some information, the cache is included
|
|
|
1404 in the dumped Emacs, and is then inaccurate on any other host.

1407 ** HP-UX

|
|
|
1409 but I haven't changed anything.
|
|
|
1410
|
|
|
1411 The default HP keymap is set up to have Mod1 assigned to two different keys:
|
|
|
1412 Meta_L and Mode_switch (even though there is not actually a Mode_switch key on
|
|
|
1413 the keyboard -- it uses an "imaginary" keycode.) There actually is a reason
|
|
|
1414 for this, but it's not a good one. The correct fix is to execute this command
|
|
|
1415 upon starting X:
|
|
|
1416
|
|
|
1417 xmodmap -e 'remove mod1 = Mode_switch'

1430 the same behavior. I've tried various hpux patches to no avail. If

1434 for this kit, as I won't be available to do it, unless 19.14 gets

1462 *** XEmacs dumps core at startup when native audio is used. Native
|
|
|
1463 audio does not work with recent versions of HP-UX.
|
|
|
1464
|
|
|
1465 Under HP-UX 10.20 and later (e.g., HP-UX 11.XX), with native audio
|
|
|
1466 enabled, the dumped XEmacs binary ("xemacs") core dumps at startup if
|
|
|
1467 recent versions of the libAlib.sl audio shared library is used. Note
|
|
|
1468 that "temacs" will run, but "xemacs" will dump core. This, of course,
|
|
|
1469 causes the XEmacs build to fail. If GNU malloc is enabled, a stack
|
|
|
1470 trace will show XEmacs to have crashed in the "first" call to malloc().
|
|
|
1471
|
|
|
1472 This bug currently exists in all versions of XEmacs, when the undump
|
|
|
1473 mechanism is used. It is not known if using the experimental portable
|
|
|
1474 dumper will allow native audio to work.
|
|
|
1475
|
|
|
1476 **** Cause:
|
|
|
1477
|
|
|
1478 Recent versions of the HP-UX 10.20 (and later) audio shared library (in
|
|
|
1479 /opt/audio/lib), pulls in the libdce shared library, which pulls in a
|
|
|
1480 thread (libcma) library. This prevents the HP-UX undump() routine (in
|
|
|
1481 unexhp9k800.c) from properly working. What's happening is that some
|
|
|
1482 initialization routines are being called in the libcma library, *BEFORE*
|
|
|
1483 main() is called, and these initialization routines are calling
|
|
|
1484 malloc(). Unfortunately, in order for the undumper to work, XEmacs must
|
|
|
1485 adjust (move upwards) the sbrk() value *BEFORE* the first call to
|
|
|
1486 malloc(); if malloc() is called before XEmacs has properly adjusted sbrk
|
|
|
1487 (which is what is happening), dumped memory that is being used by
|
|
|
1488 XEmacs, is improperly re-allocated for use by malloc() and the dumped
|
|
|
1489 memory is corrupted. This causes XEmacs to die an horrible death.
|
|
|
1490
|
|
|
1491 It is believed that versions of the audio library past December 1998
|
|
|
1492 will trigger this problem. Under HP-UX 10.20, you probably have to
|
|
|
1493 install audio library patches to encounter this. It's probable that
|
|
|
1494 recent "fresh, out-of-the-box" HP-UX 11.XX workstations also have this
|
|
|
1495 problem. For HP-UX 10.20, it's believed that audio patch PHSS_17121 (or
|
|
|
1496 a superceeding one, like PHSS_17554, PHSS_17971, PHSS_18777, PHSS_21481,
|
|
|
1497 or PHSS_21662, etc.) will trigger this.
|
|
|
1498
|
|
|
1499 To check if your audio library will cause problems for XEmacs, run
|
|
|
1500 "chatr /opt/audio/lib/libAlib.sl". If "libdce" appears in the displayed
|
|
|
1501 shared library list, XEmacs will probably encounter problems if audio is
|
|
|
1502 enabled.
|
|
|
1503
|
|
|
1504 **** Workaround:
|
|
|
1505
|
|
|
1506 Don't enable native audio. Re-run configure without native audio
|
|
|
1507 support.
|
|
|
1508
|
|
|
1509 If your site supports it, try using NAS (Network Audio Support).
|
|
|
1510
|
|
|
1511 Try using the experimental portable dumper. It may work, or it may
|
|
|
1512 not.

1515 *** `Pid xxx killed due to text modification or page I/O error'

|
1516
|
|
|
1517 On HP-UX, you can get that error when the Emacs executable is on an NFS
|
|
|
1518 file system. HP-UX responds this way if it tries to swap in a page and
|
|

1519 does not get a response from the server within a timeout whose default
|
|
|
1520 value is just ten seconds.

1526 christos@theory.tn.cornell.edu says:

1527

1528 The problem is that in your .cshrc you have something that tries to
|
|
197
|
1529 execute `tty`. If you are not running the shell on a real tty then tty
|
|
|
1530 will print "not a tty". Csh expects one word in some places, but tty

|
|
1531 is giving it back 3.
|
|
124
|
1532
|
|
197

1533 The solution is to add a pair of quotes around `tty` to make it a

1534 single word:

|

124

1560 A certain X server for Windows had a bug which caused this.

1566 * Compatibility problems (with Emacs 18, GNU Emacs, or previous XEmacs/lemacs)

1569 *** "Symbol's value as variable is void: unread-command-char".
|
|

|
1570 "Wrong type argument: arrayp, #<keymap 143 entries>"
|
|
|
1571 "Wrong type argument: stringp, [#<keypress-event return>]"
|
|
88
|
1572
|
|
124
|
1573 There are a few incompatible changes in XEmacs, and these are the
|
|
|
1574 symptoms. Some of the emacs-lisp code you are running needs to be
|
|
|
1575 updated to be compatible with XEmacs.
|
|
|
1576
|
|
|
1577 The code should not treat keymaps as arrays (use `define-key', etc.),
|
|
|
1578 should not use obsolete variables like `unread-command-char' (use
|
|
197
|
1579 `unread-command-events'). Many (most) of the new ways of doing things
|
|
124
|
1580 are compatible in GNU Emacs and XEmacs.
|
|
88
|
1581
|
|
197
|
1582 Modern Emacs packages (Gnus, VM, W3, efs, etc) are written to support
|
|
|
1583 GNU Emacs and XEmacs. We have provided modified versions of several
|
|
|
1584 popular emacs packages (dired, etc) which are compatible with this
|
|
|
1585 version of emacs. Check to make sure you have not set your load-path
|
|
|
1586 so that your private copies of these packages are being found before
|
|
|
1587 the versions in the lisp directory.
|
|
124
|
1588
|
|
|
1589 Make sure that your load-path and your $EMACSLOADPATH environment
|
|
|
1590 variable are not pointing at an Emacs18 lisp directory. This will
|
|
|
1591 cripple emacs.
|
|

|

|

|
1593 ** Some packages that worked before now cause the error
|
|
223
|
1594 Wrong type argument: arrayp, #<face ... >
|
|
124
|
1595
|
|
197
|
1596 Code which uses the `face' accessor functions must be recompiled with
|
|
|
1597 xemacs 19.9 or later. The functions whose callers must be recompiled
|
|
|
1598 are: face-font, face-foreground, face-background,
|
|
|
1599 face-background-pixmap, and face-underline-p. The .elc files
|
|
|
1600 generated by version 19.9 will work in 19.6 and 19.8, but older .elc
|
|
|
1601 files which contain calls to these functions will not work in 19.9.
|
|

|
1603 ** Signaling: (error "Byte code stack underflow (byte compiler bug), pc 38")
|
|
88
|
1604
|
|
120
|
1605 This error is given when XEmacs 20 is compiled without MULE support
|
|
88
|
1606 but is attempting to load a .elc which requires MULE support. The fix
|
|
|
1607 is to rebytecompile the offending file.

|
1611 The is seen when installing the Insidious Big Brother Data Base (bbdb)
|
|
|
1612 which includes an outdated copy of mail-abbrevs.el. Remove the copy
|
|
|
1613 that comes with bbdb and use the one that comes with XEmacs.

1616 * MULE issues
|
|
197
|
1617 =============
|
|
144
|
1618
|
|
223
|
1619 ** A reminder: XEmacs/Mule work does not currently receive *any*
|
|
|
1620 funding, and all work is done by volunteers. If you think you can
|
|
|
1621 help, please contact the XEmacs maintainers.
|
|
|
1622
|
|
278
|
1623 ** XEmacs/Mule doesn't support TTY's satisfactorily.
|
|
223
|
1624
|
|
|
1625 This is a major problem, which we plan to address in a future release
|
|
|
1626 of XEmacs. Basically, XEmacs should have primitives to be told
|
|
|
1627 whether the terminal can handle international output, and which
|
|
|
1628 locale. Also, it should be able to do approximations of characters to
|
|
|
1629 the nearest supported by the locale.
|
|
|
1630
|
|
197
|
1631 ** Internationalized (Asian) Isearch doesn't work.
|
|
144
|
1632
|
|
|
1633 Currently, Isearch doesn't directly support any of the input methods
|
|
|
1634 that are not XIM based (like egg, canna and quail) (and there are
|
|
223
|
1635 potential problems with XIM version too...). If you're using egg
|
|
|
1636 there is a workaround. Hitting <RET> right after C-s to invoke
|
|
|
1637 Isearch will put Isearch in string mode, where a complete string can
|
|
|
1638 be typed into the minibuffer and then processed by Isearch afterwards.
|
|
|
1639 Since egg is now supported in the minibuffer using string mode you can
|
|
|
1640 now use egg to input your Japanese, Korean or Chinese string, then hit
|
|
|
1641 return to send that to Isearch and then use standard Isearch commands
|
|
|
1642 from there.
|
|
144
|
1643
|
|
223
|
1644 ** Using egg and mousing around while in 'fence' mode screws up my
|
|
|
1645 buffer.
|
|
144
|
1646
|
|
|
1647 Don't do this. The fence modes of egg and canna are currently very
|
|
|
1648 modal, and messing with where they expect point to be and what they
|
|
|
1649 think is the current buffer is just asking for trouble. If you're
|
|
|
1650 lucky they will realize that something is awry, and simply delete the
|
|
|
1651 fence, but worst case can trash other buffers too. We've tried to
|
|
|
1652 protect against this where we can, but there still are many ways to
|
|
|
1653 shoot yourself in the foot. So just finish what you are typing into
|
|
|
1654 the fence before reaching for the mouse.
|
|
223
|
1655
|
|
|
1656 ** Not all languages in Quail are supported like Devanagari and Indian
|
|
|
1657 languages, Lao and Tibetan.
|
|
|
1658
|
|
|
1659 Quail requires more work and testing. Although it has been ported to
|
|
|
1660 XEmacs, it works really well for Japanese and for the European
|
|
|
1661 languages.
|
|
|
1662
|
|
|
1663 ** Right-to-left mode is not yet implemented, so languages like
|
|
|
1664 Arabic, Hebrew and Thai don't work.
|
|
|
1665
|
|
|
1666 Getting this right requires more work. It may be implemented in a
|
|
|
1667 future XEmacs version, but don't hold your breath. If you know
|
|
|
1668 someone who is ready to implement this, please let us know.
|
|
|
1669
|
|
|
1670 ** We need more developers and native language testers. It's extremely
|
|
|
1671 difficult (and not particularly productive) to address languages that
|
|
|
1672 nobody is using and testing.
|
|
|
1673
|
|
|
1674 ** The kWnn and cWnn support for Chinese and Korean needs developers
|
|
|
1675 and testers. It probably doesn't work.
|
|
|
1676
|
|
|
1677 ** There are no `native XEmacs' TUTORIALs for any Asian languages,
|
|
|
1678 including Japanese. FSF Emacs and XEmacs tutorials are quite similar,
|
|
|
1679 so it should be sufficient to skim through the differences and apply
|
|
|
1680 them to the Japanese version.
|
|
|
1681
|
|
|
1682 ** We only have localized menus translated for Japanese, and the
|
|
|
1683 Japanese menus are developing bitrot (the Mule menu appears in
|
|
|
1684 English).
|
|
|
1685
|
|
|
1686 ** XIM is untested for any language other than Japanese.
