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:
|
124
|
10
|
197
|
11 - Problems with building XEmacs
|
|
12 - Problems with running XEmacs
|
|
13 - Compatibility problems
|
|
14 - Mule issues

|
16 Use `C-c C-f' to move to the next equal level of outline, and
|
223
|
17 `C-c C-b' to move to previous equal level. `C-h m' will give more
|
|
18 info about the Outline mode.
|
120
|
19
|
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
|
398
|
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
|
398
|
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
|
392
|
147 *** The libXt shipped with AIX 4.3 is broken. This causes xemacs -nw
|
|
148 to fail in various ways. The solution is to build against stock
|
|
149 X11R6.
|
|
150
|
373
|
151 *** On AIX, you get this compiler error message:
|
|
152
|
|
153 Processing include file ./XMenuInt.h
|
|
154 1501-106: (S) Include file X11/Xlib.h not found.
|
|
155
|
|
156 This means your system was installed with only the X11 runtime i.d
|
|
157 libraries. You have to find your sipo (bootable tape) and install
|
|
158 X11Dev... with smit.
|
|
159
|
|
160 *** On AIX 4.1.2, linker error messages such as
|
|
161 ld: 0711-212 SEVERE ERROR: Symbol .__quous, found in the global symbol table
|
|
162 of archive /usr/lib/libIM.a, was not defined in archive member shr.o.
|
|
163
|
|
164 This is a problem in libIM.a. You can work around it by executing
|
|
165 these shell commands in the src subdirectory of the directory where
|
|
166 you build Emacs:
|
|
167
|
|
168 cp /usr/lib/libIM.a .
|
|
169 chmod 664 libIM.a
|
|
170 ranlib libIM.a
|
|
171
|
|
172 Then change -lIM to ./libIM.a in the command to link temacs (in
|
|
173 Makefile).
|
|
174
|
|
175 *** Excessive optimization on AIX 4.2 can lead to compiler failure.

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

179 (3.1.4.4), there are problems with -O3. I haven't investigated
|
|
180 further.
|
|
181
|
|
182
|
|
183 ** SunOS/Solaris
|
|
184 *** Link failure when using acc on a Sun.
|
|
185
|
|
186 To use acc, you need additional options just before the libraries, such as
|
|
187
|
|
188 /usr/lang/SC2.0.1/values-Xt.o -L/usr/lang/SC2.0.1/cg87 -L/usr/lang/SC2.0.1
|
|
189
|
|
190 and you need to add -lansi just before -lc.
|
|
191
|
|
192 The precise file names depend on the compiler version, so we
|
|
193 cannot easily arrange to supply them.
|
|
194
|
|
195 *** Problems finding X11 libraries on Solaris with Openwindows
|
|
196
|
|
197 Some users have reported problems in this area. The reported solution
|
|
198 is to define the environment variable OPENWINHOME, even if you must set
|
|
199 it to `/usr/openwin'.
|
|
200
|
|
201 *** Sed problems on Solaris 2.5
|
|
202
|
|
203 There have been reports of Sun sed truncating very lines in the
|
|
204 Makefile during configuration. The workaround is to use GNU sed or,
|
|
205 even better, think of a better way to generate Makefile, and send us a
|
|
206 patch. :-)
|
|
207
|
|
208 *** On Solaris 2 I get undefined symbols from libcurses.a.
|
|
209
|
|
210 You probably have /usr/ucblib/ on your LD_LIBRARY_PATH. Do the link with
|
|
211 LD_LIBRARY_PATH unset. Generally, avoid using any ucb* stuff when
|
|
212 building XEmacs.
|
|
213
|
|
214 *** On Solaris 2 I cannot make alloc.o, glyphs.o or process.o.
|
|
215
|
|
216 The SparcWorks C compiler may have difficulty building those modules
|
|
217 with optimization level -xO4. Try using only "-fast" optimization
|
|
218 for just those modules. (Or use gcc).
|
|
219
|
|
220 *** Solaris 2.3 /bin/sh coredumps during configuration.
|
|
221
|
|
222 This only occurs if you have LANG != C. This is a known bug with
|
|
223 /bin/sh fixed by installing Patch-ID# 101613-01. Or, you can use
|
|
224 bash, as a workaround.
|
|
225
|
|
226 *** On SunOS, you get linker errors
|
|
227 ld: Undefined symbol
|
|
228 _get_wmShellWidgetClass
|
|
229 _get_applicationShellWidgetClass
|
|
230
|
|
231 The fix to this is to install patch 100573 for OpenWindows 3.0
|
|
232 or link libXmu statically.
|
|
233
|
|
234 *** On Sunos 4, you get the error ld: Undefined symbol __lib_version.
|
|
235
|
|
236 This is the result of using cc or gcc with the shared library meant
|
|
237 for acc (the Sunpro compiler). Check your LD_LIBRARY_PATH and delete
|
|
238 /usr/lang/SC2.0.1 or some similar directory.
|
|
239
|
|
240 *** Undefined symbols when linking on Sunos 4.1.
|
|
241
|
|
242 If you get the undefined symbols _atowc _wcslen, _iswprint, _iswspace,
|
|
243 _iswcntrl, _wcscpy, and _wcsncpy, then you need to add -lXwchar after
|
|
244 -lXaw in the command that links temacs.
|
|
245
|
|
246 This problem seems to arise only when the international language
|
|
247 extensions to X11R5 are installed.
|
|
248
|
|
249 *** On a Sun running SunOS 4.1.1, you get this error message from GNU ld:
|
|
250
|
|
251 /lib/libc.a(_Q_sub.o): Undefined symbol __Q_get_rp_rd referenced from text segment
|
|
252
|
|
253 The problem is in the Sun shared C library, not in GNU ld.
|
|
254
|
|
255 The solution is to install Patch-ID# 100267-03 from Sun.
|
|
256
|
|
257 *** SunOS 4.1.2: undefined symbol _get_wmShellWidgetClass
|
|
258
|
|
259 Apparently the version of libXmu.so.a that Sun ships is hosed: it's missing
|
|
260 some stuff that is in libXmu.a (the static version). Sun has a patch for
|
|
261 this, but a workaround is to use the static version of libXmu, by changing
|
|
262 the link command from "-lXmu" to "-Bstatic -lXmu -Bdynamic". If you have
|
|
263 OpenWindows 3.0, ask Sun for these patches:
|
|
264 100512-02 4.1.x OpenWindows 3.0 libXt Jumbo patch
|
|
265 100573-03 4.1.x OpenWindows 3.0 undefined symbols with shared libXmu
|
|
266
|
|
267 *** Random other SunOS 4.1.[12] link errors.
|
|
268
|
|
269 The X headers and libraries that Sun ships in /usr/{include,lib}/X11 are
|
|
270 broken. Use the ones in /usr/openwin/{include,lib} instead.
|
|
271
|
|
272 ** Linux
|
|
273 *** Under Linux, you get "too many arguments to function `getpgrp'".
|
|
274
|
|
275 You have probably installed LessTiff under `/usr/local' and `libXm.so'
|
|
276 could not be found when linking `getpgrp()' test program, making XEmacs
|
|
277 think that `getpgrp()' takes an argument. Try adding `/usr/local/lib'
|
|
278 in `/etc/ld.so.conf' and run `ldconfig'. Then run XEmacs's `configure'
|
|
279 again. As with all problems of this type, reading the config.log file
|
|
280 generated from configure and seeing the log of how the test failed can
|
|
281 prove enlightening.
|
|
282
|
|
283 *** `Error: No ExtNode to pop!' on Linux systems with Lesstif.
|
197
|
284
|
|
285 This error message has been observed with lesstif-0.75a. It does not
|
|
286 appear to cause any harm.
|
|
287
|
373
|
288 *** xemacs: can't resolve symbol '__malloc_hook'
|
|
289
|
|
290 This is a Linux problem where you've compiled the XEmacs binary on a libc
|
|
291 5.4 with version higher than 5.4.19 and attempted to run the binary against
|
|
292 an earlier version. The solution is to upgrade your old library.
|
|
293
|
|
294 ** IRIX
|
|
295 *** Linking with -rpath on IRIX.
|
124
|
296
|
|
297 Darrell Kindred <dkindred@cmu.edu> writes:
|
|
298 There are a couple of problems [with use of -rpath with Irix ld], though:
|
|
299
|
|
300 1. The ld in IRIX 5.3 ignores all but the last -rpath
|
|
301 spec, so the patched configure spits out a warning
|
|
302 if --x-libraries or --site-runtime-libraries are
|
|
303 specified under irix 5.x, and it only adds -rpath
|
|
304 entries for the --site-runtime-libraries. This bug was
|
|
305 fixed sometime between 5.3 and 6.2.
|
|
306
|
|
307 2. IRIX gcc 2.7.2 doesn't accept -rpath directly, so
|
|
308 it would have to be prefixed by -Xlinker or "-Wl,".
|
|
309 This would be fine, except that configure compiles with
|
|
310 ${CC-cc} $CFLAGS $LDFLAGS ...
|
|
311 rather than quoting $LDFLAGS with prefix-args, like
|
|
312 src/Makefile does. So if you specify --x-libraries
|
|
313 or --site-runtime-libraries, you must use --use-gcc=no,
|
|
314 or configure will fail.
|
|
315
|
373
|
316 *** On Irix 6.3, the SGI ld quits with segmentation fault when linking temacs
|
207
|
317
|
|
318 This occurs if you use the SGI linker version 7.1. Installing the
|
|
319 patch SG0001872 fixes this problem.

373

321 *** On Irix 6.0, make tries (and fails) to build a program named unexelfsgi
|
|
322
|
|
323 A compiler bug inserts spaces into the string "unexelfsgi . o"
|
|
324 in src/Makefile. Edit src/Makefile, after configure is run,
|
|
325 find that string, and take out the spaces.
|
|
326
|
|
327 Compiler fixes in Irix 6.0.1 should eliminate this problem.
|
124
|
328
|
373
|
329 *** On Irix 5.2, unexelfsgi.c can't find cmplrs/stsupport.h.
|
124
|
330
|
373
|
331 The file cmplrs/stsupport.h was included in the wrong file set in the
|
|
332 Irix 5.2 distribution. You can find it in the optional fileset
|
|
333 compiler_dev, or copy it from some other Irix 5.2 system. A kludgy
|
|
334 workaround is to change unexelfsgi.c to include sym.h instead of
|
|
335 syms.h.

|
|
355 compiler to abort. When this happens: cd src, compile the files by
|
|
356 hand, cd .., and redo the "make" command. When recompiling the files by
|
|
357 hand, use the old C compiler for the following versions of Digital UNIX:
|
|
358 - V3.n: Remove "-migrate" from the compile command.
|
|
359 - V4.n: Add "-oldc" to the compile command.
|
|
360
|

|
361 A related compiler bug has been fixed by the DEC compiler team. The
|
|
362 new versions of the compiler should run fine.

412

398
|
413 Unfortunately, XEmacs releases prior to 21.0 don't work with
|
|
414 Motif2.1. It will compile but you will get excessive X11 errors like
|
304
|
415
|
|
416 xemacs: X Error of failed request: BadGC (invalid GC parameter)
|
|
417
|

418 and finally XEmacs gets killed. A workaround is to use the
|
|
419 Motif1.2_R6 libraries. You can the following line to your call to
|
|
420 configure:
|
|
421
|
|
422 --x-libraries="/usr/lib/Motif1.2_R6 -L/usr/lib/X11R6"
|
|
423
|
|
424 Make sure /usr/lib/Motif1.2_R6/libXm.sl is a link to

427 ** SCO OpenServer
|
|
428 *** Native cc on SCO OpenServer 5 is now OK. Icc may still throw you
|
197
|
429 a curve. Here is what Robert Lipe <robertl@arnet.com> says:
|
124
|
430
|
|
431 Unlike XEmacs 19.13, building with the native cc on SCO OpenServer 5
|
|
432 now produces a functional binary. I will typically build this
|
|
433 configuration for COFF with:
|
|
434
|
197
|
435 /path_to_xemacs_source/configure --with-gcc=no \
|
124
|
436 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
437 --with-xpm --with-xface --with-sound=nas
|
|
438
|
|
439 This version now supports ELF builds. I highly recommend this to
|
|
440 reduce the in-core footprint of XEmacs. This is now how I compile
|
|
441 all my test releases. Build it like this:
|
|
442
|
|
443 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
444 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
445 --with-xpm --with-xface --with-sound=nas --dynamic
|
|
446
|
|
447 The compiler known as icc [ supplied with the OpenServer 5 Development
|
|
448 System ] generates a working binary, but it takes forever to generate
|
|
449 XEmacs. ICC also whines more about the code than /bin/cc does. I do
|
|
450 believe all its whining is legitimate, however. Note that you do
|
|
451 have to 'cd src ; make LD=icc' to avoid linker errors.
|
|
452
|
|
453 The way I handle the build procedure is:
|
|
454
|
|
455 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
456 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
457 --with-xpm --with-xface --with-sound=nas --dynamic --compiler="icc"
|
|
458
|
|
459 NOTE I have the xpm, xface, and audio libraries and includes in
|
|
460 /usr/local/lib, /usr/local/include. If you don't have these,
|
|
461 don't include the "--with-*" arguments in any of my examples.
|
|
462
|
|
463 In previous versions of XEmacs, you had to override the defaults while
|
|
464 compiling font-lock.o and extents.o when building with icc. This seems
|
|
465 to no longer be true, but I'm including this old information in case it
|
|
466 resurfaces. The process I used was:
|
|
467
|
|
468 make -k
|
|
469 [ procure pizza, beer, repeat ]
|
|
470 cd src
|
|
471 make CC="icc -W0,-mP1COPT_max_tree_size=3000" font-lock.o extents.o
|
|
472 make LD=icc
|
|
473
|
|
474 If you want sound support, get the tls566 supplement from
|
|
475 ftp.sco.com:/TLS or any of its mirrors. It works just groovy
|
|
476 with XEmacs.
|
|
477
|
|
478 The M-x manual-entry is known not to work. If you know Lisp and would
|
|
479 like help in making it work, e-mail me at <robertl@dgii.com>.
|
|
480 (UNCHECKED for 19.15 -- it might work).
|
|
481
|
|
482 In earlier releases, gnuserv/gnuclient/gnudoit would open a frame
|
|
483 just fine, but the client would lock up and the server would
|
|
484 terminate when you used C-x # to close the frame. This is now
|
|
485 fixed in XEmacs.
|
|
486
|
|
487 In etc/ there are two files of note. emacskeys.sco and emacsstrs.sco.
|
|
488 The comments at the top of emacskeys.sco describe its function, and
|
|
489 the emacstrs.sco is a suitable candidate for /usr/lib/keyboard/strings
|
|
490 to take advantage of the keyboard map in emacskeys.sco.
|
|
491
|
373
|
492 Note: Much of the above entry is probably not valid for XEmacs 21.0
|
207
|
493 and later.

495 ** Cygwin
|
|
496 *** In general use etc/check_cygwin_setup.sh to trap environment problems.
|
|
497
|
|
498 The script etc/check_cygwin_setup.sh will attempt to detect whether
|
|
499 you have a suitable environment for building. This script may not work
|
|
500 correctly if you are using ash instead of bash (see below).
|
|
501
|
|
502 *** X11 not detected.
|
|
503
|
|
504 This is usually because xmkmf is not in your path or because you are
|
|
505 using the default cygwin shell. The default cygwin shell (/bin/sh.exe)
|
|
506 is ash which appears to work in most circumstances but has some wierd
|
|
507 failure modes. I recommend replacing sh.exe with bash.exe, this will
|
|
508 mean configure is slower but more reliable.
|
|
509
|
|
510 *** Subprocesses do not work.
|
|
511
|
|
512 You do not have "tty" in your CYGWIN32 (for b19) or CYGWIN (for b20)
|
|
513 environment variable. This must be set in your autoexec.bat (win95) or
|
|
514 the system properties (winnt) as it must be read before the cygwin dll
|
|
515 initializes.
|
|
516
|
|
517 *** ^G does not work on hung subprocesses.
|
|
518
|
|
519 This is a known problem. It can be remedied with cygwin b20 or greater
|
|
520 by defining BROKEN_SIGIO in src/s/cygwin32.h, however this currently
|
|
521 leads to instability in XEmacs.
|
|
522
|
|
523 *** The XEmacs executable crashes at startup.
|
|
524
|
|
525 This can be caused by many things.
|
|
526
|
|
527 If you are running with X11 you need to have cygwin b19 or cygwin
|
|
528 b20.1 or greater, cygwin b20 will not work.
|
|
529
|
|
530 If you are running with cygwin b19 make sure you are using egcs 1.0.2
|
|
531 rather than vanilla gcc. XEmacs builds by default with -O3 which does
|
|
532 not work with the gcc that ships with b19. Alternatively use -O2.
|
|
533
|
|
534 *** The info files will not build.
|
|
535
|
|
536 makeinfo that ships with cygwin (all versions) is a noop. You need to
|
|
537 obtain makeinfo from somewhere or build it yourself.
|
|
538
|
|
539 *** I have no graphics.
|
|
540
|
|
541 You need to obtain the various graphics libraries. Pre-built versions
|
|
542 of these and the X libraries are located on the XEmacs website in
|
|
543 ftp://ftp.xemacs.org/pub/aux/cygwin*.
|
|
544
|
|
545 *** There are no images in the toolbar buttons.
|
|
546
|
|
547 You need version 4.71 of commctrl.dll which does not ship with windows
|
|
548 95. You can get this by installing IE 4.0 or downloading it from the
|
|
549 microsoft website.

552 * Problems with running XEmacs
|
|
553 ==============================
|
|
554 ** General
|
|
555 *** C-z just refreshes the screen instead of suspending Emacs.
|
124
|
556
|
|
557 You are probably using a shell that doesn't support job control, even
|
197
|
558 though the system itself is capable of it. Try using a different
|
|
559 shell.
|
124
|
560
|
373
|
561 *** You type Control-H (Backspace) expecting to delete characters.
|
124
|
562
|
|
563 Emacs has traditionally used Control-H for help; unfortunately this
|
398
|
564 interferes with its use as Backspace on TTY's. As of XEmacs 21,
|
|
565 XEmacs looks at the "erase" setting of TTY structures and maps C-h to
|
|
566 backspace when erase is set to C-h. This is sort of a special hack,
|
|
567 but it makes it possible for you to use the standard:
|
|
568
|
|
569 stty erase ^H
|
355
|
570
|
398
|
571 to get your backspace key to erase characters. The erase setting is
|
|
572 recorded in the Lisp variable `tty-erase-char', which you can use to
|
|
573 tune the settings in your .emacs.
|
124
|
574
|
398
|
575 A major drawback of this is that when C-h becomes backspace, it no
|
|
576 longer invokes help. In that case, you need to use f1 for help, or
|
|
577 bind another key. An example of the latter is the following code,
|
|
578 which moves help to Meta-? (ESC ?):
|
124
|
579
|
398
|
580 (global-set-key "\M-?" 'help-command)
|
124
|
581
|
373
|
582 *** Mail agents (VM, Gnus, rmail) cannot get new mail
|
197
|
583
|
|
584 rmail and VM get new mail from /usr/spool/mail/$USER using a program
|
|
585 called `movemail'. This program interlocks with /bin/mail using the
|
|
586 protocol defined by /bin/mail.
|
|
587
|
|
588 There are two different protocols in general use. One of them uses
|
|
589 the `flock' system call. The other involves creating a lock file;
|
|
590 `movemail' must be able to write in /usr/spool/mail in order to do
|
|
591 this. You control which one is used by defining, or not defining, the
|
|
592 macro MAIL_USE_FLOCK in config.h or the m- or s- file it includes. IF
|
|
593 YOU DON'T USE THE FORM OF INTERLOCKING THAT IS NORMAL ON YOUR SYSTEM,
|
|
594 YOU CAN LOSE MAIL!
|
|
595
|
|
596 If your system uses the lock file protocol, and fascist restrictions
|
|
597 prevent ordinary users from writing the lock files in /usr/spool/mail,
|
|
598 you may need to make `movemail' setgid to a suitable group such as
|
|
599 `mail'. To do this, use the following commands (as root) after doing
|
|
600 the make install.
|
|
601
|
|
602 chgrp mail movemail
|
|
603 chmod 2755 movemail
|
|
604
|
|
605 Installation normally copies movemail from the build directory to an
|
|
606 installation directory which is usually under /usr/local/lib. The
|
|
607 installed copy of movemail is usually in the directory
|
|
608 /usr/local/lib/emacs/VERSION/TARGET. You must change the group and
|
|
609 mode of the installed copy; changing the group and mode of the build
|
|
610 directory copy is ineffective.
|
|
611
|
373
|
612 *** VM appears to hang in large folders.
|
124
|
613
|
|
614 This is normal (trust us) when upgrading to VM-6.22 from earlier
|
|
615 versions. Let VM finish what it is doing and all will be well.
|
|
616
|
373
|
617 *** Changes made to .el files do not take effect.
|
0
|
618
|
197
|
619 You may have forgotten to recompile them into .elc files. Then the
|
|
620 old .elc files will be loaded, and your changes will not be seen. To
|
|
621 fix this, do `M-x byte-recompile-directory' and specify the directory
|
|
622 that contains the Lisp files.
|
0
|
623

197

|
|
625 older than the corresponding .el file.

627 *** Things which should be bold or italic (such as the initial
|

|
628 copyright notice) are not.
|
0
|
629
|
197
|
630 The fonts of the "bold" and "italic" faces are generated from the font
|
|
631 of the "default" face; in this way, your bold and italic fonts will
|
|
632 have the appropriate size and family. However, emacs can only be
|
|
633 clever in this way if you have specified the default font using the
|
|
634 XLFD (X Logical Font Description) format, which looks like
|
0
|
635
|
|
636 *-courier-medium-r-*-*-*-120-*-*-*-*-*-*
|
|
637
|
197
|
638 if you use any of the other, less strict font name formats, some of
|
|
639 which look like:
|
|
640
|

|
641 lucidasanstypewriter-12
|
|
642 and fixed
|
|
643 and 9x13
|
|
644
|
|
645 then emacs won't be able to guess the names of the "bold" and "italic"
|
|
646 versions. All X fonts can be referred to via XLFD-style names, so you
|
|
647 should use those forms. See the man pages for X(1), xlsfonts(1), and

|
648 xfontsel(1).

650 *** The dumped Emacs crashes when run, trying to write pure data.
|
0
|
651
|
|
652 Two causes have been seen for such problems.
|
|
653
|
|
654 1) On a system where getpagesize is not a system call, it is defined
|
|
655 as a macro. If the definition (in both unexec.c and malloc.c) is wrong,
|
|
656 it can cause problems like this. You might be able to find the correct
|
|
657 value in the man page for a.out (5).
|
|
658
|
|
659 2) Some systems allocate variables declared static among the
|
|
660 initialized variables. Emacs makes all initialized variables in most
|
|
661 of its files pure after dumping, but the variables declared static and
|
|
662 not initialized are not supposed to be pure. On these systems you
|
|
663 may need to add "#define static" to the m- or the s- file.
|
|
664
|
373
|
665 *** Reading and writing files is very very slow.
|
0
|
666
|
|
667 Try evaluating the form (setq lock-directory nil) and see if that helps.
|
|
668 There is a problem with file-locking on some systems (possibly related
|
|
669 to NFS) that I don't understand. Please send mail to the address
|
|
670 xemacs@xemacs.org if you figure this one out.
|
|
671
|
373
|
672 *** When emacs starts up, I get lots of warnings about unknown keysyms.
|
124
|
673
|
|
674 If you are running the prebuilt binaries, the Motif library expects to find
|
|
675 certain thing in the XKeysymDB file. This file is normally in /usr/lib/X11/
|
|
676 or in /usr/openwin/lib/. If you keep yours in a different place, set the
|
|
677 environment variable $XKEYSYMDB to point to it before starting emacs. If
|
|
678 you still have the problem after doing that, perhaps your version of X is
|
|
679 too old. There is a copy of the MIT X11R5 XKeysymDB file in the emacs `etc'
|
|
680 directory. Try using that one.
|
|
681
|
373
|
682 *** My X resources used to work, and now some of them are being ignored.
|
0
|
683
|
124
|
684 Check the resources in .../etc/Emacs.ad (which is the same as the file
|
|
685 sample.Xdefaults). Perhaps some of the default resources built in to
|
|
686 emacs are now overriding your existing resources. Copy and edit the
|
|
687 resources in Emacs.ad as necessary.
|
|
688
|
373
|
689 *** I have focus problems when I use `M-o' to switch to another screen
|
197
|
690 without using the mouse.
|
124
|
691
|
197
|
692 The focus issues with a program like XEmacs, which has multiple
|
|
693 homogeneous top-level windows, are very complicated, and as a result,
|
|
694 most window managers don't implement them correctly.

|
|
716 This means that Control-S/Control-Q (XON/XOFF) "flow control" is being
|
|
717 used. C-s/C-q flow control is bad for Emacs editors because it takes
|
|
718 away C-s and C-q as user commands. Since editors do not output long
|
|
719 streams of text without user commands, there is no need for a
|
|
720 user-issuable "stop output" command in an editor; therefore, a
|
|
721 properly designed flow control mechanism would transmit all possible
|
|
722 input characters without interference. Designing such a mechanism is
|
|
723 easy, for a person with at least half a brain.
|
|
724
|
|
725 There are three possible reasons why flow control could be taking place:
|
|
726
|
|
727 1) Terminal has not been told to disable flow control
|
|
728 2) Insufficient padding for the terminal in use
|
|
729 3) Some sort of terminal concentrator or line switch is responsible
|
|
730
|
|
731 First of all, many terminals have a set-up mode which controls whether
|
|
732 they generate XON/XOFF flow control characters. This must be set to
|
|
733 "no XON/XOFF" in order for Emacs to work. Sometimes there is an
|
|
734 escape sequence that the computer can send to turn flow control off
|
|
735 and on. If so, perhaps the termcap `ti' string should turn flow
|
|
736 control off, and the `te' string should turn it on.
|
|
737
|
|
738 Once the terminal has been told "no flow control", you may find it
|
|
739 needs more padding. The amount of padding Emacs sends is controlled
|
|
740 by the termcap entry for the terminal in use, and by the output baud
|
|
741 rate as known by the kernel. The shell command `stty' will print
|
|
742 your output baud rate; `stty' with suitable arguments will set it if
|
|
743 it is wrong. Setting to a higher speed causes increased padding. If
|
|
744 the results are wrong for the correct speed, there is probably a
|
|
745 problem in the termcap entry. You must speak to a local Unix wizard
|
|
746 to fix this. Perhaps you are just using the wrong terminal type.
|
|
747
|
|
748 For terminals that lack a "no flow control" mode, sometimes just
|
|
749 giving lots of padding will prevent actual generation of flow control
|
|
750 codes. You might as well try it.
|
|
751
|
|
752 If you are really unlucky, your terminal is connected to the computer
|
|
753 through a concentrator which sends XON/XOFF flow control to the
|
|
754 computer, or it insists on sending flow control itself no matter how
|
|
755 much padding you give it. Unless you can figure out how to turn flow
|
|
756 control off on this concentrator (again, refer to your local wizard),
|
|
757 you are screwed! You should have the terminal or concentrator
|
|
758 replaced with a properly designed one. In the mean time, some drastic
|
|
759 measures can make Emacs semi-work.
|
|
760
|
|
761 You can make Emacs ignore C-s and C-q and let the operating system
|
|
762 handle them. To do this on a per-session basis, just type M-x
|
|
763 enable-flow-control RET. You will see a message that C-\ and C-^ are
|
|
764 now translated to C-s and C-q. (Use the same command M-x
|
|
765 enable-flow-control to turn *off* this special mode. It toggles flow
|
|
766 control handling.)
|
|
767
|
|
768 If C-\ and C-^ are inconvenient for you (for example, if one of them
|
|
769 is the escape character of your terminal concentrator), you can choose
|
|
770 other characters by setting the variables flow-control-c-s-replacement
|
|
771 and flow-control-c-q-replacement. But choose carefully, since all
|
|
772 other control characters are already used by emacs.
|
|
773
|
|
774 IMPORTANT: if you type C-s by accident while flow control is enabled,
|
|
775 Emacs output will freeze, and you will have to remember to type C-q in
|
|
776 order to continue.
|
|
777
|
|
778 If you work in an environment where a majority of terminals of a
|
|
779 certain type are flow control hobbled, you can use the function
|
|
780 `enable-flow-control-on' to turn on this flow control avoidance scheme
|
|
781 automatically. Here is an example:
|
|
782
|
|
783 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")
|
|
784
|
|
785 If this isn't quite correct (e.g. you have a mixture of flow-control hobbled
|
|
786 and good vt200 terminals), you can still run enable-flow-control
|
|
787 manually.
|
|
788
|
|
789 I have no intention of ever redesigning the Emacs command set for the
|
|
790 assumption that terminals use C-s/C-q flow control. XON/XOFF flow
|
|
791 control technique is a bad design, and terminals that need it are bad
|
|
792 merchandise and should not be purchased. Now that X is becoming
|
|
793 widespread, XON/XOFF seems to be on the way out. If you can get some
|
|
794 use out of GNU Emacs on inferior terminals, more power to you, but I
|
|
795 will not make Emacs worse for properly designed systems for the sake
|
|
796 of inferior systems.

798 *** Control-S and Control-Q commands are ignored completely.
|
0
|
799
|
|
800 For some reason, your system is using brain-damaged C-s/C-q flow
|
|
801 control despite Emacs's attempts to turn it off. Perhaps your
|
|
802 terminal is connected to the computer through a concentrator
|
|
803 that wants to use flow control.
|
|
804
|
|
805 You should first try to tell the concentrator not to use flow control.
|
|
806 If you succeed in this, try making the terminal work without
|
|
807 flow control, as described in the preceding section.
|
|
808
|
|
809 If that line of approach is not successful, map some other characters
|
|
810 into C-s and C-q using keyboard-translate-table. The example above
|
|
811 shows how to do this with C-^ and C-\.

816 Some versions of rlogin (and possibly telnet) do not pass flow
|
|
817 control characters to the remote system to which they connect.
|
|
818 On such systems, emacs on the remote system cannot disable flow
|
|
819 control on the local system.
|
|
820
|
|
821 One way to cure this is to disable flow control on the local host
|
|
822 (the one running rlogin, not the one running rlogind) using the
|
|
823 stty command, before starting the rlogin process. On many systems,
|
120
|
824 `stty start u stop u' will do this.
|
0
|
825
|
|
826 Some versions of tcsh will prevent even this from working. One way
|
|
827 around this is to start another shell before starting rlogin, and
|
|
828 issue the stty command to disable flow control from that shell.
|
|
829
|
|
830 If none of these methods work, the best solution is to type
|
120
|
831 `M-x enable-flow-control' at the beginning of your emacs session, or
|
0
|
832 if you expect the problem to continue, add a line such as the
|
|
833 following to your .emacs (on the host running rlogind):
|
|
834
|
|
835 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")

|
197
|
841
|

842 XEmacs has fairly new TTY redisplay support (beginning from 19.12),
|
|
843 which doesn't include some basic TTY optimizations -- like using
|
|
844 scrolling regions to move around blocks of text. This is why
|
|
845 redisplay on the traditional terminals, or over slow lines can be very
|
|
846 slow.
|
|
847
|
|

852
|
120
|
853 This could mean that the termcap entry you are using for that terminal

|
|
855 combination of features specified for that terminal.
|
0
|
856
|
|
857 The first step in tracking this down is to record what characters
|
|
858 Emacs is sending to the terminal. Execute the Lisp expression
|
120
|
859 (open-termscript "./emacs-script") to make Emacs write all terminal
|
|
860 output into the file ~/emacs-script as well; then do what makes the
|
|
861 screen update wrong, and look at the file and decode the characters
|
|
862 using the manual for the terminal. There are several possibilities:
|
0
|
863
|
|
864 1) The characters sent are correct, according to the terminal manual.
|
|
865
|
|
866 In this case, there is no obvious bug in Emacs, and most likely you
|
|
867 need more padding, or possibly the terminal manual is wrong.
|
|
868
|
120
|
869 2) The characters sent are incorrect, due to an obscure aspect of the
|
|
870 terminal behavior not described in an obvious way by termcap.
|
0
|
871
|
120
|
872 This case is hard. It will be necessary to think of a way for Emacs
|
|
873 to distinguish between terminals with this kind of behavior and other
|
|
874 terminals that behave subtly differently but are classified the same
|
|
875 by termcap; or else find an algorithm for Emacs to use that avoids the
|
|
876 difference. Such changes must be tested on many kinds of terminals.

|
881 needed in commonly used termcap entries for certain terminals.
|
0
|
882
|
120
|
883 4) The characters sent are incorrect, and clearly cannot be right for
|
|
884 any terminal with the termcap entry you were using.

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

|
|
888 redisplay-output.c, or redisplay.c.

897

898 twm normally ignores "program-specified" positions.

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

901 UsePPosition "on" #allow clents to request a position

903 *** With M-x enable-flow-control, you need to type C-\ twice to do

|
904 incremental search--a single C-\ gets no response.
|
|
905
|
|
906 This has been traced to communicating with your machine via kermit,
|
|
907 with C-\ as the kermit escape character. One solution is to use
|
|
908 another escape character in kermit. One user did
|
|
909
|
|
910 set escape-character 17
|
|
911
|
|
912 in his .kermrc file, to make C-q the kermit escape character.

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

|
|
918 Emacs*default.attributeFont: -*-courier-medium-r-*-*-*-140-*-*-*-*-iso8859-*
|
|
919
|
|
920 That the resource has this effect indicates a bug in something, but we
|
|
921 do not yet know what. If it is an Emacs bug, we hope someone can
|
|
922 explain what the bug is so we can fix it. In the mean time, removing
|
|
923 the resource prevents the problem.
|
|
924
|
|
925 *** After running emacs once, subsequent invocations crash.
|
|
926
|
|
927 Some versions of SVR4 have a serious bug in the implementation of the
|
|
928 mmap () system call in the kernel; this causes emacs to run correctly
|
|
929 the first time, and then crash when run a second time.
|
|
930
|
|
931 Contact your vendor and ask for the mmap bug fix; in the mean time,
|
|
932 you may be able to work around the problem by adding a line to your
|
|
933 operating system description file (whose name is reported by the
|
|
934 configure script) that reads:
|
|
935 #define SYSTEM_MALLOC
|
|
936 This makes Emacs use memory less efficiently, but seems to work around
|
|
937 the kernel bug.
|
|
938
|
|
939 *** Inability to send an Alt-modified key, when Emacs is communicating
|
|
940 directly with an X server.
|
|
941
|
|
942 If you have tried to bind an Alt-modified key as a command, and it
|
|
943 does not work to type the command, the first thing you should check is
|
|
944 whether the key is getting through to Emacs. To do this, type C-h c
|
|
945 followed by the Alt-modified key. C-h c should say what kind of event
|
|
946 it read. If it says it read an Alt-modified key, then make sure you
|
|
947 have made the key binding correctly.
|
|
948
|
|
949 If C-h c reports an event that doesn't have the Alt modifier, it may
|
|
950 be because your X server has no key for the Alt modifier. The X
|
|
951 server that comes from MIT does not set up the Alt modifier by
|
|
952 default.
|
|
953
|
|
954 If your keyboard has keys named Alt, you can enable them as follows:
|
|
955
|
|
956 xmodmap -e 'add mod2 = Alt_L'
|
|
957 xmodmap -e 'add mod2 = Alt_R'
|
|
958
|
|
959 If the keyboard has just one key named Alt, then only one of those
|
|
960 commands is needed. The modifier `mod2' is a reasonable choice if you
|
|
961 are using an unmodified MIT version of X. Otherwise, choose any
|
|
962 modifier bit not otherwise used.
|
|
963
|
|
964 If your keyboard does not have keys named Alt, you can use some other
|
|
965 keys. Use the keysym command in xmodmap to turn a function key (or
|
|
966 some other 'spare' key) into Alt_L or into Alt_R, and then use the
|
|
967 commands show above to make them modifier keys.
|
|
968
|
|
969 Note that if you have Alt keys but no Meta keys, Emacs translates Alt
|
|
970 into Meta. This is because of the great importance of Meta in Emacs.
|
|

|
|
972 *** In Shell mode, you get a ^M at the end of every line.
|
|
973
|
|
974 This happens to people who use tcsh, because it is trying to be too
|
|
975 smart. It sees that the Shell uses terminal type `unknown' and turns
|
|
976 on the flag to output ^M at the end of each line. You can fix the
|
|
977 problem by adding this to your .cshrc file:
|
|
978
|
|
979 if ($?EMACS) then
|
|
980 if ($EMACS == "t") then
|

|
|
1003
|
|
1004 OLWM grabs the help key, and retransmits it to the appropriate client
|
|
1005 using XSendEvent. Allowing emacs to react to synthetic events is a
|
|
1006 security hole, so this is turned off by default. You can enable it by
|
|
1007 setting the variable x-allow-sendevents to t. You can also cause fix
|

1008 this by telling OLWM to not grab the help key, with the null binding
|

1009 "OpenWindows.KeyboardCommand.Help:".

|
|
1013
|

1014 The cause of this is a shell startup file that sets the TERMCAP
|

1015 environment variable. The terminal emulator uses that variable to
|
|
1016 provide the information on the special terminal type that Emacs
|
|
1017 emulates.
|
|
1018
|
|
1019 Rewrite your shell startup file so that it does not change TERMCAP
|
|
1020 in such a case. You could use the following conditional which sets
|
|
1021 it only if it is undefined.
|
|
1022
|
|
1023 if ( ! ${?TERMCAP} ) setenv TERMCAP ~/my-termcap-file
|
|
1024
|
|
1025 Or you could set TERMCAP only when you set TERM--which should not

1026 happen in a non-login shell.

1094 you have probably compiled using an ANSI C compiler, but with non-ANSI

1095 include files. In particular, on Suns, the file
|
|
1096 /usr/include/sun/audioio.h uses the _IOW macro to define the constant
|
|
1097 AUDIOSETQSIZE. _IOW in turn uses a K&R preprocessor feature that is
|
|
1098 now explicitly forbidden in ANSI preprocessors, namely substitution
|
|
1099 inside character constants. All ANSI C compilers must provide a
|
|
1100 workaround for this problem. Lucid's C compiler is shipped with a new
|
|
1101 set of system include files. If you are using GCC, there is a script
|
|
1102 called fixincludes that creates new versions of some system include
|
|
1103 files that use this obsolete feature.

1123 casper@fwi.uva.nl says the problem is in X11R6. Rebuild libX11.so

1124 after changing the file xc/config/cf/sunLib.tmpl. Change the lines
|
|
1125
|
|
1126 #if ThreadedX
|
|
1127 #define SharedX11Reqs -lthread
|
|

|
|
1137
|
|
1138 Be sure also to edit x/config/cf/sun.cf so that OSMinorVersion is 4
|
|
1139 (as it should be for Solaris 2.4). The file has three definitions for
|
|
1140 OSMinorVersion: the first is for x86, the second for SPARC under
|
|
1141 Solaris, and the third for SunOS 4. Make sure to update the
|
|
1142 definition for your type of machine and system.
|
|
1143
|
|
1144 Then do `make Everything' in the top directory of X11R6, to rebuild

1145 the makefiles and rebuild X. The X built this way work only on

1158 in sun.cf and did `make World' to rebuild X11R6. Removing all

1169 *** Mail is lost when sent to local aliases.
|
0
|
1170
|
124
|
1171 Many emacs mail user agents (VM and rmail, for instance) use the
|
|
1172 sendmail.el library. This library can arrange for mail to be
|
|
1173 delivered by passing messages to the /usr/lib/sendmail (usually)
|
|
1174 program . In doing so, it passes the '-t' flag to sendmail, which
|
|
1175 means that the name of the recipient of the message is not on the
|
|
1176 command line and, therefore, that sendmail must parse the message to
|
|
1177 obtain the destination address.
|
|
1178
|
|
1179 There is a bug in the SunOS4.1.1 and SunOS4.1.3 versions of sendmail.
|
|
1180 In short, when given the -t flag, the SunOS sendmail won't recognize
|
|
1181 non-local (i.e. NIS) aliases. It has been reported that the Solaris
|
|
1182 2.x versions of sendmail do not have this bug. For those using SunOS
|
|
1183 4.1, the best fix is to install sendmail V8 or IDA sendmail (which
|
|
1184 have other advantages over the regular sendmail as well). At the time
|
|
1185 of this writing, these official versions are available:
|
|
1186
|
|
1187 Sendmail V8 on ftp.cs.berkeley.edu in /ucb/sendmail:
|
|
1188 sendmail.8.6.9.base.tar.Z (the base system source & documentation)
|

1200
|
124
|
1201 This typically happens on Suns and other systems that use shared
|
|
1202 libraries. The cause is that the site has installed a version of the
|
|
1203 shared library which uses a name server--but has not installed a
|
|
1204 similar version of the unshared library which Emacs uses.
|
0
|
1205
|
124
|
1206 The result is that most programs, using the shared library, work with
|
|
1207 the nameserver, but Emacs does not.
|
|
1208
|
|
1209 The fix is to install an unshared library that corresponds to what you
|
|
1210 installed in the shared library, and then relink Emacs.

1212 On SunOS 4.1, simply define HAVE_RES_INIT.
|
|
1213
|
|
1214 If you have already installed the name resolver in the file libresolv.a,
|
|
1215 then you need to compile Emacs to use that library. The easiest way to
|
|
1216 do this is to add to config.h a definition of LIBS_SYSTEM, LIBS_MACHINE
|
|
1217 or LIB_STANDARD which uses -lresolv. Watch out! If you redefine a macro
|
|
1218 that is already in use in your configuration to supply some other libraries,
|
|
1219 be careful not to lose the others.
|
|
1220
|
|
1221 Thus, you could start by adding this to config.h:
|
|
1222
|
|
1223 #define LIBS_SYSTEM -lresolv
|
|
1224
|
|
1225 Then if this gives you an error for redefining a macro, and you see that
|
|
1226 the s- file defines LIBS_SYSTEM as -lfoo -lbar, you could change config.h
|
|
1227 again to say this:
|
|
1228
|
|
1229 #define LIBS_SYSTEM -lresolv -lfoo -lbar

1234 On SunOS systems, this problem has been seen to be a result of an
|
|
1235 incomplete installation of gcc 2.2 which allowed some non-ANSI
|
|
1236 compatible include files into the compilation. In particular this
|
|
1237 affected virtually all ioctl() calls.

1242
|
|
1243 Internationalization was not the top priority for GNU Libc 2.0.
|
|
1244 As of this writing (1998-12-28) you may get crashes while running
|
|
1245 XEmacs in a non-C locale. For example, `LC_ALL=en_US xemacs' crashes
|
|
1246 while `LC_ALL=C xemacs' runs fine. This happens for example with GNU
|
|
1247 libc 2.0.7. Installing libintl.a and libintl.h built from gettext
|
|
1248 0.10.35 and re-building XEmacs solves the crashes. Presumably soon
|
|
1249 everyone will upgrade to GNU Libc 2.1 and this problem will go away.

|
|
1254 because gpm installs a buggy SIGTSTP handler. Either compile with

1261 One user on a Linux system reported that this problem went away with
|
|
1262 installation of a new X server. The failing server was XFree86 3.1.1.

1263 XFree86 3.1.2 works.

1265 *** Slow startup on Linux.
|
|
1266
|
|
1267 People using systems based on the Linux kernel sometimes report that
|
|
1268 startup takes 10 to 15 seconds longer than `usual'.
|
|
1269
|
|
1270 This is because Emacs looks up the host name when it starts.
|
|
1271 Normally, this takes negligible time; the extra delay is due to
|
|
1272 improper system configuration. This problem can occur for both
|
|
1273 networked and non-networked machines.
|
|
1274
|
|
1275 Here is how to fix the configuration. It requires being root.
|
|
1276
|
|
1277 **** Networked Case
|
|
1278
|
|
1279 First, make sure the files `/etc/hosts' and `/etc/host.conf' both
|
|
1280 exist. The first line in the `/etc/hosts' file should look like this
|
|
1281 (replace HOSTNAME with your host name):
|
|
1282
|
|
1283 127.0.0.1 localhost HOSTNAME
|
|
1284
|
|
1285 Also make sure that the `/etc/host.conf' files contains the following
|
|
1286 lines:
|
|
1287
|
|
1288 order hosts, bind
|
|
1289 multi on
|
|
1290
|
|
1291 Any changes, permanent and temporary, to the host name should be
|
|
1292 indicated in the `/etc/hosts' file, since it acts a limited local
|
|
1293 database of addresses and names (e.g., some SLIP connections
|
|
1294 dynamically allocate ip addresses).
|
|
1295
|
|
1296 **** Non-Networked Case
|
|
1297
|
|
1298 The solution described in the networked case applies here as well.
|
|
1299 However, if you never intend to network your machine, you can use a
|
|
1300 simpler solution: create an empty `/etc/host.conf' file. The command
|
|
1301 `touch /etc/host.conf' suffices to create the file. The `/etc/hosts'
|
|
1302 file is not necessary with this approach.
|
|
1303
|
|
1304
|
|
1305 ** IRIX
|
|
1306 *** On Irix, I don't see the toolbar icons and I'm getting lots of
|
|
1307 entries in the warnings buffer.
|
|
1308
|
|
1309 SGI ships a really old Xpm library in /usr/lib which does not work at
|
|
1310 all well with XEmacs. The solution is to install your own copy of the
|
|
1311 latest version of Xpm somewhere and then use the --site-includes and
|
|
1312 --site-libraries flags to tell configure where to find it.
|
|
1313
|
|
1314 *** Trouble using ptys on IRIX, or running out of ptys.
|
|
1315
|
|
1316 The program mkpts (which may be in `/usr/adm' or `/usr/sbin') needs to
|
|
1317 be set-UID to root, or non-root programs like Emacs will not be able
|
|
1318 to allocate ptys reliably.
|
|

|
|
1338 *** XEmacs crashes on Digital Unix within font-lock, or when dealing
|
|
1339 with large compilation buffers.
|
|
1340
|
|
1341 The default stack size under Digital Unix is rather small (2M as
|
|
1342 opposed to Solaris 8M), hosing the regexp code, which uses alloca()
|
|
1343 extensively, overflowing the stack when complex regexps are used.
|
|
1344 Workarounds:
|
312
|
1345
|
373
|
1346 1) Increase your stack size, using `ulimit -s 8192' or a (t)csh
|
|
1347 equivalent;
|
|
1348
|
|
1349 2) Recompile regex.c with REGEX_MALLOC defined.

|
1351 *** The `Alt' key doesn't behave as `Meta' when running DECwindows.
|
|
1352
|
|
1353 The default DEC keyboard mapping has the Alt keys set up to generate the
|
|
1354 keysym `Multi_key', which has a meaning to xemacs which is distinct from that
|
|
1355 of the `Meta_L' and `Meta-R' keysyms. A second problem is that certain keys
|
|
1356 have the Mod2 modifier attached to them for no adequately explored reason.
|
|
1357 The correct fix is to pass this file to xmodmap upon starting X:
|
|
1358
|
|
1359 clear mod2
|
|
1360 keysym Multi_key = Alt_L
|
|
1361 add mod1 = Alt_L
|
|
1362 add mod1 = Alt_R
|
|
1363
|
|
1364 *** The Compose key on a DEC keyboard does not work as Meta key.
|
|
1365
|
|
1366 This shell command should fix it:
|
|
1367
|
|
1368 xmodmap -e 'keycode 0xb1 = Meta_L'
|
|
1369
|
|
1370 *** `expand-file-name' fails to work on any but the machine you dumped
|
|
1371 Emacs on.
|
|
1372
|
|
1373 On Ultrix, if you use any of the functions which look up information
|
|
1374 in the passwd database before dumping Emacs (say, by using
|
|
1375 expand-file-name in site-init.el), then those functions will not work
|
|
1376 in the dumped Emacs on any host but the one Emacs was dumped on.
|
|
1377
|
|
1378 The solution? Don't use expand-file-name in site-init.el, or in
|
|
1379 anything it loads. Yuck - some solution.
|
|
1380
|
|
1381 I'm not sure why this happens; if you can find out exactly what is
|
|
1382 going on, and perhaps find a fix or a workaround, please let us know.
|
|
1383 Perhaps the YP functions cache some information, the cache is included
|
|
1384 in the dumped Emacs, and is then inaccurate on any other host.

1389 but I haven't changed anything.
|
|
1390
|
|
1391 The default HP keymap is set up to have Mod1 assigned to two different keys:
|
|
1392 Meta_L and Mode_switch (even though there is not actually a Mode_switch key on
|
|
1393 the keyboard -- it uses an "imaginary" keycode.) There actually is a reason
|
|
1394 for this, but it's not a good one. The correct fix is to execute this command
|
|
1395 upon starting X:
|
|
1396
|
|
1397 xmodmap -e 'remove mod1 = Mode_switch'
|

1405 event (mouse, keyboard, expose...) results in a "poll: Interrupted
|
|
1406 system call" message in the window where XEmacs was
|
|
1407 launched. Forcing a static link of libc.a alone by adding
|
|
1408 /usr/lib/libc.a at the end of the link line solves this. Note that
|
|
1409 my 9.07 build of 19.14b17 and my (old) build of 19.13 both exhibit
|
|
1410 the same behaviour. I've tried various hpux patches to no avail. If
|
|
1411 this problem cannot be solved before the release date, binary kits
|
|
1412 for HP *must* be linked statically against libc, otherwise this
|
|
1413 problem will show up. (This is directed at whoever will volunteer
|
|
1414 for this kit, as I won't be available to do it, unless 19.14 gets
|
|
1415 delayed until mid-june ;-). I think this problem will be an FAQ soon
|
|
1416 after the release otherwise.

1421 *** The right Alt key works wrong on German HP keyboards (and perhaps

1422 other non-English HP keyboards too).
|
|
1423
|
|
1424 This is because HP-UX defines the modifiers wrong in X. Here is a
|
|
1425 shell script to fix the problem; be sure that it is run after VUE
|

1441 *** `Pid xxx killed due to text modification or page I/O error'
|

1442
|
|
1443 On HP-UX, you can get that error when the Emacs executable is on an NFS
|
|
1444 file system. HP-UX responds this way if it tries to swap in a page and
|
|
1445 does not get a response from the server within a timeout whose default
|
|
1446 value is just ten seconds.
|
|
1447
|
|
1448 If this happens to you, extend the timeout period.

1452 christos@theory.tn.cornell.edu says:
|
|
1453
|
|
1454 The problem is that in your .cshrc you have something that tries to
|
197
|
1455 execute `tty`. If you are not running the shell on a real tty then tty
|
|
1456 will print "not a tty". Csh expects one word in some places, but tty
|
|
1457 is giving it back 3.
|
124
|
1458
|
197
|
1459 The solution is to add a pair of quotes around `tty` to make it a
|
|
1460 single word:
|
0
|
1461
|
124
|
1462 if (`tty` == "/dev/console")
|
|
1463
|
|
1464 should be changed to:
|
|
1465
|
|
1466 if ("`tty`" == "/dev/console")
|
|
1467
|
|
1468 Even better, move things that set up terminal sections out of .cshrc
|
|
1469 and into .login.

1492 * Compatibility problems (with Emacs 18, GNU Emacs, or previous XEmacs/lemacs)
|
197
|
1493 ==============================================================================

|
1494

|
1495 *** "Symbol's value as variable is void: unread-command-char".
|
197
|
1496 "Wrong type argument: arrayp, #<keymap 143 entries>"
|
|
1497 "Wrong type argument: stringp, [#<keypress-event return>]"
|
88
|
1498
|
124
|
1499 There are a few incompatible changes in XEmacs, and these are the
|
|
1500 symptoms. Some of the emacs-lisp code you are running needs to be
|
|
1501 updated to be compatible with XEmacs.
|
|
1502
|
|
1503 The code should not treat keymaps as arrays (use `define-key', etc.),
|
|
1504 should not use obsolete variables like `unread-command-char' (use
|
197
|
1505 `unread-command-events'). Many (most) of the new ways of doing things
|
124
|
1506 are compatible in GNU Emacs and XEmacs.
|
88
|
1507
|
197
|
1508 Modern Emacs packages (Gnus, VM, W3, efs, etc) are written to support
|
|
1509 GNU Emacs and XEmacs. We have provided modified versions of several
|
|
1510 popular emacs packages (dired, etc) which are compatible with this
|
|
1511 version of emacs. Check to make sure you have not set your load-path
|
|
1512 so that your private copies of these packages are being found before
|
|
1513 the versions in the lisp directory.
|
124
|
1514
|
|
1515 Make sure that your load-path and your $EMACSLOADPATH environment
|
|
1516 variable are not pointing at an Emacs18 lisp directory. This will
|
|
1517 cripple emacs.

1521
|
197
|
1522 Code which uses the `face' accessor functions must be recompiled with
|
|
1523 xemacs 19.9 or later. The functions whose callers must be recompiled
|
|
1524 are: face-font, face-foreground, face-background,
|
|
1525 face-background-pixmap, and face-underline-p. The .elc files
|
|
1526 generated by version 19.9 will work in 19.6 and 19.8, but older .elc
|
|
1527 files which contain calls to these functions will not work in 19.9.

|
1531 This error is given when XEmacs 20 is compiled without MULE support
|
88
|
1532 but is attempting to load a .elc which requires MULE support. The fix
|
|
1533 is to rebytecompile the offending file.

1542 * MULE issues
|
197
|
1543 =============
|
144
|
1544
|
223
|
1545 ** A reminder: XEmacs/Mule work does not currently receive *any*
|
|
1546 funding, and all work is done by volunteers. If you think you can
|
|
1547 help, please contact the XEmacs maintainers.
|
|
1548
|
278
|
1549 ** XEmacs/Mule doesn't support TTY's satisfactorily.
|
223
|
1550
|
|
1551 This is a major problem, which we plan to address in a future release
|
|
1552 of XEmacs. Basically, XEmacs should have primitives to be told
|
|
1553 whether the terminal can handle international output, and which
|
|
1554 locale. Also, it should be able to do approximations of characters to
|
|
1555 the nearest supported by the locale.
|
|
1556
|
197
|
1557 ** Internationalized (Asian) Isearch doesn't work.
|
144
|
1558
|
|
1559 Currently, Isearch doesn't directly support any of the input methods
|
|
1560 that are not XIM based (like egg, canna and quail) (and there are
|
223
|
1561 potential problems with XIM version too...). If you're using egg
|
|
1562 there is a workaround. Hitting <RET> right after C-s to invoke
|
|
1563 Isearch will put Isearch in string mode, where a complete string can
|
|
1564 be typed into the minibuffer and then processed by Isearch afterwards.
|
|
1565 Since egg is now supported in the minibuffer using string mode you can
|
|
1566 now use egg to input your Japanese, Korean or Chinese string, then hit
|
|
1567 return to send that to Isearch and then use standard Isearch commands
|
|
1568 from there.
|
144
|
1569
|
223
|
1570 ** Using egg and mousing around while in 'fence' mode screws up my
|
|
1571 buffer.
|
144
|
1572
|
|
1573 Don't do this. The fence modes of egg and canna are currently very
|
|
1574 modal, and messing with where they expect point to be and what they
|
|
1575 think is the current buffer is just asking for trouble. If you're
|
|
1576 lucky they will realize that something is awry, and simply delete the
|
|
1577 fence, but worst case can trash other buffers too. We've tried to
|
|
1578 protect against this where we can, but there still are many ways to
|
|
1579 shoot yourself in the foot. So just finish what you are typing into
|
|
1580 the fence before reaching for the mouse.
|
223
|
1581
|
|
1582 ** Not all languages in Quail are supported like Devanagari and Indian
|
|
1583 languages, Lao and Tibetan.
|
|
1584
|
|
1585 Quail requires more work and testing. Although it has been ported to
|
|
1586 XEmacs, it works really well for Japanese and for the European
|
|
1587 languages.
|
|
1588
|
|
1589 ** Right-to-left mode is not yet implemented, so languages like
|
|
1590 Arabic, Hebrew and Thai don't work.
|
|
1591
|
|
1592 Getting this right requires more work. It may be implemented in a
|
|
1593 future XEmacs version, but don't hold your breath. If you know
|
|
1594 someone who is ready to implement this, please let us know.
|
|
1595
|
|
1596 ** We need more developers and native language testers. It's extremely
|
|
1597 difficult (and not particularly productive) to address languages that
|
|
1598 nobody is using and testing.
|
|
1599
|
|
1600 ** The kWnn and cWnn support for Chinese and Korean needs developers
|
|
1601 and testers. It probably doesn't work.
|
|
1602
|
|
1603 ** There are no `native XEmacs' TUTORIALs for any Asian languages,
|
|
1604 including Japanese. FSF Emacs and XEmacs tutorials are quite similar,
|
|
1605 so it should be sufficient to skim through the differences and apply
|
|
1606 them to the Japanese version.
|
|
1607
|
|
1608 ** We only have localized menus translated for Japanese, and the
|
|
1609 Japanese menus are developing bitrot (the Mule menu appears in
|
|
1610 English).
|
|
1611
|
|
1612 ** XIM is untested for any language other than Japanese.
