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:

|
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
|
|
335
|
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
|
|
327
|
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
|
|
312
|
44 *** Don't use -O2 with gcc 2.7.2 under Intel/XXX without also using
|
|
223
|
45 `-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
|
|
312
|
53 *** Don't use -O2 with gcc 2.7.2 under Intel architectures without also
|
|
229
|
54 using `-fno-caller-saves'.
|
|
|
55
|
|
263
|
56 gcc will generate incorrect code otherwise. This bug is still
|
|
|
57 present in gcc 2.7.2.3. There have been no reports to indicate the
|
|
|
58 bug is present in egcs 1.0 (or pgcc 1.0) or later. This bug is O/S
|
|
|
59 independent, but limited to x86 architectures.
|
|
|
60
|
|
|
61 This problem is known to be fixed in egcs (or pgcc) 1.0 or later.
|
|
124
|
62
|
|
312
|
63 *** When using gcc, you get the error message "undefined symbol __fixunsdfsi".
|
|
|
64 When using gcc, you get the error message "undefined symbol __main".
|
|
|
65
|
|
|
66 This means that you need to link with the gcc library. It may be called
|
|
|
67 "gcc-gnulib" or "libgcc.a"; figure out where it is, and define LIB_GCC in
|
|
|
68 config.h to point to it.
|
|
|
69
|
|
|
70 It may also work to use the GCC version of `ld' instead of the standard one.
|
|
|
71
|
|
|
72 *** Excessive optimization with pgcc can break XEmacs
|
|
124
|
73
|
|
|
74 It has been reported on some systems that compiling with -O6 can lead
|
|
|
75 to XEmacs failures. The workaround is to use a lower optimization
|
|
|
76 level. -O2 and -O4 have been tested extensively.
|
|
|
77
|
|
229
|
78 All of this depends heavily on the version of pgcc and the version
|
|
|
79 of libc. Snapshots near the release of pgcc-1.0 have been tested
|
|
|
80 extensively and no sign of breakage has been seen on systems using
|
|
|
81 glibc-2.
|
|
|
82
|
|
312
|
83 *** src/Makefile and lib-src/Makefile are truncated--most of the file missing.
|
|
229
|
84
|
|
312
|
85 This can happen if configure uses GNU sed version 2.03. That version
|
|
|
86 had a bug. GNU sed version 2.05 works properly.
|
|
124
|
87
|
|
312
|
88 *** When compiling with X11, you get "undefined symbol _XtStrings".
|
|
124
|
89
|
|
312
|
90 This means that you are trying to link emacs against the X11r4 version of
|
|
|
91 libXt.a, but you have compiled either Emacs or the code in the lwlib
|
|
|
92 subdirectory with the X11r5 header files. That doesn't work.
|
|
124
|
93
|
|
312
|
94 Remember, you can't compile lwlib for r4 and emacs for r5, or vice versa.
|
|
|
95 They must be in sync.
|
|
124
|
96
|
|
312
|
97 *** test-distrib says that the distribution has been clobbered
|
|
197
|
98 or, temacs prints "Command key out of range 0-127"
|
|
|
99 or, temacs runs and dumps xemacs, but xemacs totally fails to work.
|
|
|
100 or, temacs gets errors dumping xemacs
|
|
|
101
|
|
|
102 This can be because the .elc files have been garbled. Do not be
|
|
|
103 fooled by the fact that most of a .elc file is text: these are binary
|
|
|
104 files and can contain all 256 byte values.
|
|
|
105
|
|
|
106 In particular `shar' cannot be used for transmitting GNU Emacs. It
|
|
|
107 typically truncates "lines". (this does not apply to GNU shar, which
|
|
|
108 uses uuencode to encode binary files.)
|
|
|
109
|
|
|
110 If you have a copy of Emacs that has been damaged in its nonprinting
|
|
|
111 characters, you can fix them by running:
|
|
|
112
|
|
|
113 make all-elc
|
|
|
114
|
|
|
115 This will rebuild all the needed .elc files.
|
|
|
116
|
|
312
|
117 *** `compress' and `uncompress' not found and XFree86
|
|
|
118
|
|
|
119 XFree86 installs a very old version of libz.a by default ahead of where
|
|
|
120 more modern version of libz might be installed. This will cause problems
|
|
|
121 when attempting to link against libMagick. The fix is to remove the old
|
|
|
122 libz.a in the X11 binary directory.
|
|
|
123
|
|
|
124
|
|
|
125 ** AIX
|
|
316
|
126 *** On AIX 4.3, you must specify --with-dialogs=athena with configure
|
|
|
127
|
|
361
|
128 *** The libXt shipped with AIX 4.3 up to 4.3.2 is broken. This causes
|
|
|
129 xemacs -nw to fail in various ways. The official APAR is this:
|
|
|
130
|
|
|
131 APAR NUMBER: <IX89470> RESOLVED AS: PROGRAM ERROR
|
|
|
132
|
|
|
133 ABSTRACT:
|
|
|
134 <IX89470>: LIBXT.A INCORRECT HANDLING OF EXCEPTIONS IN XTAPPADDINPUT
|
|
|
135
|
|
|
136 The solution is to install X11.base.lib at version >=4.3.2.5.
|
|
333
|
137
|
|
312
|
138 *** On AIX, you get this compiler error message:
|
|
|
139
|
|
|
140 Processing include file ./XMenuInt.h
|
|
|
141 1501-106: (S) Include file X11/Xlib.h not found.
|
|
|
142
|
|
|
143 This means your system was installed with only the X11 runtime i.d
|
|
|
144 libraries. You have to find your sipo (bootable tape) and install
|
|
|
145 X11Dev... with smit.
|
|
|
146
|
|
|
147 *** On AIX 4.1.2, linker error messages such as
|
|
|
148 ld: 0711-212 SEVERE ERROR: Symbol .__quous, found in the global symbol table
|
|
|
149 of archive /usr/lib/libIM.a, was not defined in archive member shr.o.
|
|
|
150
|
|
|
151 This is a problem in libIM.a. You can work around it by executing
|
|
|
152 these shell commands in the src subdirectory of the directory where
|
|
|
153 you build Emacs:
|
|
|
154
|
|
|
155 cp /usr/lib/libIM.a .
|
|
|
156 chmod 664 libIM.a
|
|
|
157 ranlib libIM.a
|
|
|
158
|
|
|
159 Then change -lIM to ./libIM.a in the command to link temacs (in
|
|
|
160 Makefile).
|
|
|
161
|
|
|
162 *** Excessive optimization on AIX 4.2 can lead to compiler failure.

170 ** SunOS/Solaris
|
|
369
|
171 *** Dumping error when using GNU binutils / GNU ld on a Sun.
|
|
|
172
|
|
|
173 Errors similar to the following:
|
|
|
174
|
|
|
175 Dumping under the name xemacs unexec():
|
|
|
176 dldump(/space/rpluim/xemacs-obj/src/xemacs): ld.so.1: ./temacs:
|
|
|
177 fatal: /space/rpluim/xemacs-obj/src/xemacs: unknown dynamic entry:
|
|
|
178 1879048176
|
|
|
179
|
|
|
180 are caused by using GNU ld. There are several workarounds available:
|
|
|
181
|
|
|
182 In XEmacs 21.2 or later, configure using the new portable dumper
|
|
|
183 (--pdump).
|
|
|
184
|
|
|
185 Alternatively, you can link using the Sun version of ld, which is
|
|
|
186 normally held in /usr/ccs/bin. This can be done by one of:
|
|
|
187
|
|
|
188 - building gcc with these configure flags:
|
|
|
189 configure --with-ld=/usr/ccs/bin/ld --with-as=/usr/ccs/bin/as
|
|
|
190
|
|
|
191 - adding -B/usr/ccs/bin/ to CFLAGS used to configure XEmacs
|
|
|
192 (Note: The trailing '/' there is significant.)
|
|
|
193
|
|
|
194 - uninstalling GNU ld.
|
|
|
195
|
|
|
196 The Solaris2 FAQ claims:
|
|
|
197
|
|
|
198 When you install gcc, don't make the mistake of installing
|
|
|
199 GNU binutils or GNU libc, they are not as capable as their
|
|
|
200 counterparts you get with Solaris 2.x.
|
|
|
201
|
|
312
|
202 *** Link failure when using acc on a Sun.
|
|
|
203
|
|
|
204 To use acc, you need additional options just before the libraries, such as
|
|
|
205
|
|
|
206 /usr/lang/SC2.0.1/values-Xt.o -L/usr/lang/SC2.0.1/cg87 -L/usr/lang/SC2.0.1
|
|
|
207
|
|
|
208 and you need to add -lansi just before -lc.
|
|
|
209
|
|
|
210 The precise file names depend on the compiler version, so we
|
|
|
211 cannot easily arrange to supply them.
|
|
|
212
|
|
|
213 *** Problems finding X11 libraries on Solaris with Openwindows
|
|
|
214
|
|
|
215 Some users have reported problems in this area. The reported solution
|
|
|
216 is to define the environment variable OPENWINHOME, even if you must set
|
|
|
217 it to `/usr/openwin'.
|
|
|
218
|
|
|
219 *** Sed problems on Solaris 2.5
|
|
|
220
|
|
|
221 There have been reports of Sun sed truncating very lines in the
|
|
|
222 Makefile during configuration. The workaround is to use GNU sed or,
|
|
|
223 even better, think of a better way to generate Makefile, and send us a
|
|
|
224 patch. :-)
|
|
|
225
|
|
|
226 *** On Solaris 2 I get undefined symbols from libcurses.a.
|
|
|
227
|
|
|
228 You probably have /usr/ucblib/ on your LD_LIBRARY_PATH. Do the link with
|
|
|
229 LD_LIBRARY_PATH unset. Generally, avoid using any ucb* stuff when
|
|
|
230 building XEmacs.
|
|
|
231
|
|
|
232 *** On Solaris 2 I cannot make alloc.o, glyphs.o or process.o.
|
|
|
233
|
|
|
234 The SparcWorks C compiler may have difficulty building those modules
|
|
|
235 with optimization level -xO4. Try using only "-fast" optimization
|
|
|
236 for just those modules. (Or use gcc).
|
|
|
237
|
|
|
238 *** Solaris 2.3 /bin/sh coredumps during configuration.
|
|
|
239
|
|
|
240 This only occurs if you have LANG != C. This is a known bug with
|
|
|
241 /bin/sh fixed by installing Patch-ID# 101613-01. Or, you can use
|
|
|
242 bash, as a workaround.
|
|
|
243
|
|
|
244 *** On SunOS, you get linker errors
|
|
|
245 ld: Undefined symbol
|
|
|
246 _get_wmShellWidgetClass
|
|
|
247 _get_applicationShellWidgetClass
|
|
|
248
|
|
|
249 The fix to this is to install patch 100573 for OpenWindows 3.0
|
|
|
250 or link libXmu statically.
|
|
|
251
|
|
|
252 *** On Sunos 4, you get the error ld: Undefined symbol __lib_version.
|
|
|
253
|
|
|
254 This is the result of using cc or gcc with the shared library meant
|
|
|
255 for acc (the Sunpro compiler). Check your LD_LIBRARY_PATH and delete
|
|
|
256 /usr/lang/SC2.0.1 or some similar directory.
|
|
|
257
|
|
|
258 *** Undefined symbols when linking on Sunos 4.1.
|
|
|
259
|
|
|
260 If you get the undefined symbols _atowc _wcslen, _iswprint, _iswspace,
|
|
|
261 _iswcntrl, _wcscpy, and _wcsncpy, then you need to add -lXwchar after
|
|
|
262 -lXaw in the command that links temacs.
|
|
|
263
|
|
|
264 This problem seems to arise only when the international language
|
|
|
265 extensions to X11R5 are installed.
|
|
|
266
|
|
|
267 *** On a Sun running SunOS 4.1.1, you get this error message from GNU ld:
|
|
|
268
|
|
|
269 /lib/libc.a(_Q_sub.o): Undefined symbol __Q_get_rp_rd referenced from text segment
|
|
|
270
|
|
|
271 The problem is in the Sun shared C library, not in GNU ld.
|
|
|
272
|
|
|
273 The solution is to install Patch-ID# 100267-03 from Sun.
|
|
|
274
|
|
|
275 *** SunOS 4.1.2: undefined symbol _get_wmShellWidgetClass
|
|
|
276
|
|
|
277 Apparently the version of libXmu.so.a that Sun ships is hosed: it's missing
|
|
|
278 some stuff that is in libXmu.a (the static version). Sun has a patch for
|
|
|
279 this, but a workaround is to use the static version of libXmu, by changing
|
|
|
280 the link command from "-lXmu" to "-Bstatic -lXmu -Bdynamic". If you have
|
|
|
281 OpenWindows 3.0, ask Sun for these patches:
|
|
|
282 100512-02 4.1.x OpenWindows 3.0 libXt Jumbo patch
|
|
|
283 100573-03 4.1.x OpenWindows 3.0 undefined symbols with shared libXmu
|
|
|
284
|
|
|
285 *** Random other SunOS 4.1.[12] link errors.
|
|
|
286
|
|
|
287 The X headers and libraries that Sun ships in /usr/{include,lib}/X11 are
|
|
|
288 broken. Use the ones in /usr/openwin/{include,lib} instead.
|
|
|
289
|
|
|
290 ** Linux
|
|
|
291 *** Under Linux, you get "too many arguments to function `getpgrp'".
|
|
|
292
|
|
|
293 You have probably installed LessTiff under `/usr/local' and `libXm.so'
|
|
|
294 could not be found when linking `getpgrp()' test program, making XEmacs
|
|
|
295 think that `getpgrp()' takes an argument. Try adding `/usr/local/lib'
|
|
|
296 in `/etc/ld.so.conf' and run `ldconfig'. Then run XEmacs's `configure'
|
|
|
297 again. As with all problems of this type, reading the config.log file
|
|
|
298 generated from configure and seeing the log of how the test failed can
|
|
|
299 prove enlightening.
|
|
|
300
|
|
|
301 *** `Error: No ExtNode to pop!' on Linux systems with Lesstif.
|
|
197
|
302
|
|
|
303 This error message has been observed with lesstif-0.75a. It does not
|
|
|
304 appear to cause any harm.

305
|
|
312
|
306 *** xemacs: can't resolve symbol '__malloc_hook'
|
|
|
307
|
|
|
308 This is a Linux problem where you've compiled the XEmacs binary on a libc
|
|
|
309 5.4 with version higher than 5.4.19 and attempted to run the binary against
|
|
|
310 an earlier version. The solution is to upgrade your old library.

|
312 ** IRIX
|
|
369
|
313
|
|
|
314 *** On Irix 6.5, the MIPSpro compiler gets an internal compiler error
|
|
|
315
|
|
|
316 The MIPSpro Compiler (at least version 7.2.1) can't seem to handle the
|
|
|
317 union type properly, and fails to compile src/glyphs.c. To avoid this
|
|
|
318 problem, always build ---use-union-type=3Dno (but that's the default, so
|
|
|
319 you should only see this problem if you're an XEmacs maintainer).
|
|
|

324 There are a couple of problems [with use of -rpath with Irix ld], though:
|
|
|
325
|
|
|
326 1. The ld in IRIX 5.3 ignores all but the last -rpath
|
|
|
327 spec, so the patched configure spits out a warning
|
|
|
328 if --x-libraries or --site-runtime-libraries are
|
|
|
329 specified under irix 5.x, and it only adds -rpath
|
|
|
330 entries for the --site-runtime-libraries. This bug was
|
|
|
331 fixed sometime between 5.3 and 6.2.
|
|
|
332
|
|
|
333 2. IRIX gcc 2.7.2 doesn't accept -rpath directly, so
|
|
|
334 it would have to be prefixed by -Xlinker or "-Wl,".
|
|
|
335 This would be fine, except that configure compiles with
|
|
|
336 ${CC-cc} $CFLAGS $LDFLAGS ...
|
|
|
337 rather than quoting $LDFLAGS with prefix-args, like
|
|
|
338 src/Makefile does. So if you specify --x-libraries
|
|
|
339 or --site-runtime-libraries, you must use --use-gcc=no,
|
|
|
340 or configure will fail.

349 A compiler bug inserts spaces into the string "unexelfsgi . o"
|
|
|
350 in src/Makefile. Edit src/Makefile, after configure is run,
|
|
|
351 find that string, and take out the spaces.
|

357 The file cmplrs/stsupport.h was included in the wrong file set in the

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

360 workaround is to change unexelfsgi.c to include sym.h instead of
|

361 syms.h.

367 that XEmacs coredumped when the cut or copy toolbar buttons were

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

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

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

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

467 ** SCO OpenServer
|
|
|
468 *** Native cc on SCO OpenServer 5 is now OK. Icc may still throw you
|
|
197
|
469 a curve. Here is what Robert Lipe <robertl@arnet.com> says:
|
|
124
|
470
|
|
|
471 Unlike XEmacs 19.13, building with the native cc on SCO OpenServer 5
|
|
|
472 now produces a functional binary. I will typically build this
|
|
|
473 configuration for COFF with:
|
|
|
474
|
|
197
|
475 /path_to_xemacs_source/configure --with-gcc=no \
|
|
124
|
476 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
477 --with-xpm --with-xface --with-sound=nas
|
|
|
478
|
|
|
479 This version now supports ELF builds. I highly recommend this to
|
|
|
480 reduce the in-core footprint of XEmacs. This is now how I compile
|
|
|
481 all my test releases. Build it like this:
|
|
|
482
|
|
|
483 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
|
484 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
485 --with-xpm --with-xface --with-sound=nas --dynamic
|
|
|
486
|
|
|
487 The compiler known as icc [ supplied with the OpenServer 5 Development
|
|
|
488 System ] generates a working binary, but it takes forever to generate
|
|
|
489 XEmacs. ICC also whines more about the code than /bin/cc does. I do
|
|
|
490 believe all its whining is legitimate, however. Note that you do
|
|
|
491 have to 'cd src ; make LD=icc' to avoid linker errors.
|
|
|
492
|
|
|
493 The way I handle the build procedure is:
|
|
|
494
|
|
|
495 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
|
496 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
497 --with-xpm --with-xface --with-sound=nas --dynamic --compiler="icc"
|
|
|
498
|
|
|
499 NOTE I have the xpm, xface, and audio libraries and includes in
|
|
|
500 /usr/local/lib, /usr/local/include. If you don't have these,
|
|
|
501 don't include the "--with-*" arguments in any of my examples.
|
|
|
502
|
|
|
503 In previous versions of XEmacs, you had to override the defaults while
|
|
|
504 compiling font-lock.o and extents.o when building with icc. This seems
|
|
|
505 to no longer be true, but I'm including this old information in case it
|
|
|
506 resurfaces. The process I used was:
|
|
|
507
|
|
|
508 make -k
|
|
|
509 [ procure pizza, beer, repeat ]
|
|
|
510 cd src
|
|
|
511 make CC="icc -W0,-mP1COPT_max_tree_size=3000" font-lock.o extents.o
|
|
|
512 make LD=icc
|
|
|
513
|
|
|
514 If you want sound support, get the tls566 supplement from
|
|
|
515 ftp.sco.com:/TLS or any of its mirrors. It works just groovy
|
|
|
516 with XEmacs.
|
|
|
517
|
|
|
518 The M-x manual-entry is known not to work. If you know Lisp and would
|
|
|
519 like help in making it work, e-mail me at <robertl@dgii.com>.
|
|
|
520 (UNCHECKED for 19.15 -- it might work).
|
|
|
521
|
|
|
522 In earlier releases, gnuserv/gnuclient/gnudoit would open a frame
|
|
|
523 just fine, but the client would lock up and the server would
|
|
|
524 terminate when you used C-x # to close the frame. This is now
|
|
|
525 fixed in XEmacs.
|
|
|
526
|
|
|
527 In etc/ there are two files of note. emacskeys.sco and emacsstrs.sco.
|
|
|
528 The comments at the top of emacskeys.sco describe its function, and
|
|
|
529 the emacstrs.sco is a suitable candidate for /usr/lib/keyboard/strings
|
|
|
530 to take advantage of the keyboard map in emacskeys.sco.
|
|
|
531
|
|
276
|
532 Note: Much of the above entry is probably not valid for XEmacs 21.0
|
|
207
|
533 and later.

535 ** Cygwin
|
|
|
536 *** In general use etc/check_cygwin_setup.sh to trap environment problems.
|
|
|
537
|
|
|
538 The script etc/check_cygwin_setup.sh will attempt to detect whether
|
|
|
539 you have a suitable environment for building. This script may not work
|
|
|
540 correctly if you are using ash instead of bash (see below).
|
|
|
541
|
|
|
542 *** X11 not detected.
|
|
|
543
|
|
|
544 This is usually because xmkmf is not in your path or because you are
|
|
|
545 using the default cygwin shell. The default cygwin shell (/bin/sh.exe)
|
|
365
|
546 is ash which appears to work in most circumstances but has some weird
|
|
333
|
547 failure modes. I recommend replacing sh.exe with bash.exe, this will
|
|
|
548 mean configure is slower but more reliable.
|
|
|
549
|
|
|
550 *** Subprocesses do not work.
|
|
|
551
|
|
|
552 You do not have "tty" in your CYGWIN32 (for b19) or CYGWIN (for b20)
|
|
|
553 environment variable. This must be set in your autoexec.bat (win95) or
|
|
|
554 the system properties (winnt) as it must be read before the cygwin dll
|
|
|
555 initializes.
|

|
556
|
|
|
557 *** ^G does not work on hung subprocesses.
|
|
|
558
|
|
|
559 This is a known problem. It can be remedied with cygwin b20 or greater
|
|
|
560 by defining BROKEN_SIGIO in src/s/cygwin32.h, however this currently
|
|
|
561 leads to instability in XEmacs.
|
|
|
562
|
|
|
563 *** The XEmacs executable crashes at startup.
|
|
|
564
|
|
|
565 This can be caused by many things.
|
|
|
566
|
|
|
567 If you are running with X11 you need to have cygwin b19 or cygwin
|
|
|
568 b20.1 or greater, cygwin b20 will not work.
|
|
|
569
|
|
|
570 If you are running with cygwin b19 make sure you are using egcs 1.0.2
|
|
|
571 rather than vanilla gcc. XEmacs builds by default with -O3 which does
|
|
|
572 not work with the gcc that ships with b19. Alternatively use -O2.
|

573
|
|
|
574 *** The info files will not build.
|
|
|
575
|
|

576 makeinfo that ships with cygwin (all versions) is a noop. You need to

|
577 obtain makeinfo from somewhere or build it yourself.
|
|
|
578
|
|
|
579 *** I have no graphics.
|
|
|
580
|
|
|
581 You need to obtain the various graphics libraries. Pre-built versions
|
|
|
582 of these and the X libraries are located on the XEmacs website in
|
|
|
583 ftp://ftp.xemacs.org/pub/aux/cygwin*.

|
584
|
|
|
585 *** There are no images in the toolbar buttons.
|

586
|
|

587 You need version 4.71 of commctrl.dll which does not ship with windows

592 * Problems with running XEmacs
|
|
|
593 ==============================
|
|
|
594 ** General
|
|
|
595 *** C-z just refreshes the screen instead of suspending Emacs.
|
|
124
|
596
|
|
|
597 You are probably using a shell that doesn't support job control, even
|
|
197
|
598 though the system itself is capable of it. Try using a different
|
|
|
599 shell.
|
|
124
|
600
|
|
312
|
601 *** You type Control-H (Backspace) expecting to delete characters.
|
|
124
|
602
|
|
|
603 Emacs has traditionally used Control-H for help; unfortunately this
|
|
355
|
604 interferes with its use as Backspace on TTY's. As of XEmacs 21,
|
|
|
605 XEmacs looks at the "erase" setting of TTY structures and maps C-h to
|
|
|
606 backspace when erase is set to C-h. This is sort of a special hack,
|
|
|
607 but it makes it possible for you to use the standard:
|
|
|
608
|
|
|
609 stty erase ^H
|
|
124
|
610
|
|
355
|
611 to get your backspace key to erase characters. The erase setting is
|
|
|
612 recorded in the Lisp variable `tty-erase-char', which you can use to
|
|
|
613 tune the settings in your .emacs.
|
|
124
|
614
|
|
355
|
615 A major drawback of this is that when C-h becomes backspace, it no
|
|
|
616 longer invokes help. In that case, you need to use f1 for help, or
|
|
|
617 bind another key. An example of the latter is the following code,
|
|
|
618 which moves help to Meta-? (ESC ?):
|
|
124
|
619
|
|
355
|
620 (global-set-key "\M-?" 'help-command)
|
|
124
|
621
|
|
312
|
622 *** Mail agents (VM, Gnus, rmail) cannot get new mail
|
|
197
|
623
|
|
|
624 rmail and VM get new mail from /usr/spool/mail/$USER using a program
|
|
|
625 called `movemail'. This program interlocks with /bin/mail using the
|
|
|
626 protocol defined by /bin/mail.
|
|

627
|
|
|
628 There are two different protocols in general use. One of them uses
|
|
|
629 the `flock' system call. The other involves creating a lock file;
|
|
|
630 `movemail' must be able to write in /usr/spool/mail in order to do
|
|
|
631 this. You control which one is used by defining, or not defining, the
|
|
|
632 macro MAIL_USE_FLOCK in config.h or the m- or s- file it includes. IF
|
|
|
633 YOU DON'T USE THE FORM OF INTERLOCKING THAT IS NORMAL ON YOUR SYSTEM,
|
|
|
634 YOU CAN LOSE MAIL!
|
|
|
635
|
|
|
636 If your system uses the lock file protocol, and fascist restrictions
|
|
|
637 prevent ordinary users from writing the lock files in /usr/spool/mail,
|
|
|
638 you may need to make `movemail' setgid to a suitable group such as
|
|
|
639 `mail'. To do this, use the following commands (as root) after doing
|
|
|
640 the make install.
|
|
|
641
|
|
|
642 chgrp mail movemail
|
|
|
643 chmod 2755 movemail
|
|
|
644
|
|
|
645 Installation normally copies movemail from the build directory to an
|
|
|
646 installation directory which is usually under /usr/local/lib. The
|
|
|
647 installed copy of movemail is usually in the directory
|
|
|
648 /usr/local/lib/emacs/VERSION/TARGET. You must change the group and
|
|
|
649 mode of the installed copy; changing the group and mode of the build
|
|
|
650 directory copy is ineffective.

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

|

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

|

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

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

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

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

|
0
|
691
|
|
|
692 Two causes have been seen for such problems.
|
|
|
693
|
|
|
694 1) On a system where getpagesize is not a system call, it is defined
|
|
|
695 as a macro. If the definition (in both unexec.c and malloc.c) is wrong,
|
|
|
696 it can cause problems like this. You might be able to find the correct
|
|
|
697 value in the man page for a.out (5).
|
|
|
698
|
|
|
699 2) Some systems allocate variables declared static among the
|
|
|
700 initialized variables. Emacs makes all initialized variables in most
|
|
|
701 of its files pure after dumping, but the variables declared static and
|
|
|
702 not initialized are not supposed to be pure. On these systems you
|
|
|
703 may need to add "#define static" to the m- or the s- file.
|
|

704
|
|

|
705 *** Reading and writing files is very very slow.

706
|

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

710 xemacs@xemacs.org if you figure this one out.

|
712 *** When emacs starts up, I get lots of warnings about unknown keysyms.
|
|
124
|
713
|
|
|
714 If you are running the prebuilt binaries, the Motif library expects to find
|
|
|
715 certain thing in the XKeysymDB file. This file is normally in /usr/lib/X11/
|
|
|
716 or in /usr/openwin/lib/. If you keep yours in a different place, set the
|
|
|
717 environment variable $XKEYSYMDB to point to it before starting emacs. If
|
|
|
718 you still have the problem after doing that, perhaps your version of X is
|
|
|
719 too old. There is a copy of the MIT X11R5 XKeysymDB file in the emacs `etc'
|
|
|
720 directory. Try using that one.

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

|
|

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

124
|
731
|
|
197
|
732 The focus issues with a program like XEmacs, which has multiple
|
|
|
733 homogeneous top-level windows, are very complicated, and as a result,
|
|
|
734 most window managers don't implement them correctly.

|
736 The R4/R5 version of twm (and all of its descendants) had buggy focus
|
|
197
|
737 handling. Sufficiently recent versions of tvtwm have been fixed. In
|
|
|
738 addition, if you're using twm, make sure you have not specified
|
|
|
739 "NoTitleFocus" in your .tvtwmrc file. The very nature of this option
|
|
|
740 makes twm do some illegal focus tricks, even with the patch.

742 It is known that olwm and olvwm are buggy, and in different ways. If

754 *** Emacs spontaneously displays "I-search: " at the bottom of the screen.
|
|
0
|
755
|
|
|
756 This means that Control-S/Control-Q (XON/XOFF) "flow control" is being
|
|
|
757 used. C-s/C-q flow control is bad for Emacs editors because it takes
|
|
|
758 away C-s and C-q as user commands. Since editors do not output long
|
|
|
759 streams of text without user commands, there is no need for a
|
|
|
760 user-issuable "stop output" command in an editor; therefore, a
|
|
|
761 properly designed flow control mechanism would transmit all possible
|
|
|
762 input characters without interference. Designing such a mechanism is
|
|
|
763 easy, for a person with at least half a brain.
|
|
|
764
|
|
|
765 There are three possible reasons why flow control could be taking place:
|
|
|
766
|
|
|
767 1) Terminal has not been told to disable flow control
|
|
|
768 2) Insufficient padding for the terminal in use
|
|
|
769 3) Some sort of terminal concentrator or line switch is responsible
|
|
|
770
|
|
|
771 First of all, many terminals have a set-up mode which controls whether
|
|
|
772 they generate XON/XOFF flow control characters. This must be set to
|
|
|
773 "no XON/XOFF" in order for Emacs to work. Sometimes there is an
|
|
|
774 escape sequence that the computer can send to turn flow control off
|
|
|
775 and on. If so, perhaps the termcap `ti' string should turn flow
|
|
|
776 control off, and the `te' string should turn it on.
|
|
|
777
|
|
|
778 Once the terminal has been told "no flow control", you may find it
|
|
|
779 needs more padding. The amount of padding Emacs sends is controlled
|
|
|
780 by the termcap entry for the terminal in use, and by the output baud
|
|
|
781 rate as known by the kernel. The shell command `stty' will print
|
|
|
782 your output baud rate; `stty' with suitable arguments will set it if
|
|
|
783 it is wrong. Setting to a higher speed causes increased padding. If
|
|
|
784 the results are wrong for the correct speed, there is probably a
|
|
|
785 problem in the termcap entry. You must speak to a local Unix wizard
|
|
|
786 to fix this. Perhaps you are just using the wrong terminal type.
|
|
|
787
|
|
|
788 For terminals that lack a "no flow control" mode, sometimes just
|
|
|
789 giving lots of padding will prevent actual generation of flow control
|
|
|
790 codes. You might as well try it.
|
|
|
791
|
|
|
792 If you are really unlucky, your terminal is connected to the computer
|
|
|
793 through a concentrator which sends XON/XOFF flow control to the
|
|
|
794 computer, or it insists on sending flow control itself no matter how
|
|
|
795 much padding you give it. Unless you can figure out how to turn flow
|
|
|
796 control off on this concentrator (again, refer to your local wizard),
|
|
|
797 you are screwed! You should have the terminal or concentrator
|
|
|
798 replaced with a properly designed one. In the mean time, some drastic
|
|
|
799 measures can make Emacs semi-work.
|
|
|
800
|
|
|
801 You can make Emacs ignore C-s and C-q and let the operating system
|
|
|
802 handle them. To do this on a per-session basis, just type M-x
|
|
|
803 enable-flow-control RET. You will see a message that C-\ and C-^ are
|
|
|
804 now translated to C-s and C-q. (Use the same command M-x
|
|
|
805 enable-flow-control to turn *off* this special mode. It toggles flow
|
|
|
806 control handling.)
|
|
|
807
|
|
|
808 If C-\ and C-^ are inconvenient for you (for example, if one of them
|
|
|
809 is the escape character of your terminal concentrator), you can choose
|
|
|
810 other characters by setting the variables flow-control-c-s-replacement
|
|
|
811 and flow-control-c-q-replacement. But choose carefully, since all
|
|
|
812 other control characters are already used by emacs.
|
|
|
813
|
|
|
814 IMPORTANT: if you type C-s by accident while flow control is enabled,
|
|
|
815 Emacs output will freeze, and you will have to remember to type C-q in
|
|
|
816 order to continue.
|
|
|
817
|
|
|
818 If you work in an environment where a majority of terminals of a
|
|
|
819 certain type are flow control hobbled, you can use the function
|
|
|
820 `enable-flow-control-on' to turn on this flow control avoidance scheme
|
|
|
821 automatically. Here is an example:
|
|
|
822
|
|
|
823 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")
|
|
|
824
|
|
|
825 If this isn't quite correct (e.g. you have a mixture of flow-control hobbled
|
|
|
826 and good vt200 terminals), you can still run enable-flow-control
|
|
|
827 manually.
|
|
|
828
|
|
|
829 I have no intention of ever redesigning the Emacs command set for the
|
|
|
830 assumption that terminals use C-s/C-q flow control. XON/XOFF flow
|
|
|
831 control technique is a bad design, and terminals that need it are bad
|
|
|
832 merchandise and should not be purchased. Now that X is becoming
|
|
|
833 widespread, XON/XOFF seems to be on the way out. If you can get some
|
|
|
834 use out of GNU Emacs on inferior terminals, more power to you, but I
|
|
|
835 will not make Emacs worse for properly designed systems for the sake
|
|
|
836 of inferior systems.

838 *** Control-S and Control-Q commands are ignored completely.
|
|
0
|
839
|
|
|
840 For some reason, your system is using brain-damaged C-s/C-q flow
|
|
|
841 control despite Emacs's attempts to turn it off. Perhaps your
|
|
|
842 terminal is connected to the computer through a concentrator
|
|
|
843 that wants to use flow control.
|
|
|
844
|
|
|
845 You should first try to tell the concentrator not to use flow control.
|
|
|
846 If you succeed in this, try making the terminal work without
|
|
|
847 flow control, as described in the preceding section.
|
|
|
848
|
|
|
849 If that line of approach is not successful, map some other characters
|
|
|
850 into C-s and C-q using keyboard-translate-table. The example above
|
|
|
851 shows how to do this with C-^ and C-\.

856 Some versions of rlogin (and possibly telnet) do not pass flow
|
|
|
857 control characters to the remote system to which they connect.
|
|
|
858 On such systems, emacs on the remote system cannot disable flow
|
|
|
859 control on the local system.
|
|
|
860
|
|
|
861 One way to cure this is to disable flow control on the local host
|
|
|
862 (the one running rlogin, not the one running rlogind) using the
|
|
|
863 stty command, before starting the rlogin process. On many systems,
|
|
120
|
864 `stty start u stop u' will do this.
|
|
0
|
865
|
|
|
866 Some versions of tcsh will prevent even this from working. One way
|
|
|
867 around this is to start another shell before starting rlogin, and
|
|
|
868 issue the stty command to disable flow control from that shell.
|
|
|
869
|
|
|
870 If none of these methods work, the best solution is to type
|
|
120
|
871 `M-x enable-flow-control' at the beginning of your emacs session, or
|
|
0
|
872 if you expect the problem to continue, add a line such as the
|
|
|
873 following to your .emacs (on the host running rlogind):
|
|
|
874
|
|
|
875 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")

|
|
197
|
881
|
|
|
882 XEmacs has fairly new TTY redisplay support (beginning from 19.12),
|
|
|
883 which doesn't include some basic TTY optimizations -- like using
|
|
|
884 scrolling regions to move around blocks of text. This is why
|
|
|
885 redisplay on the traditional terminals, or over slow lines can be very
|
|
|
886 slow.

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

|
896
|

897 The first step in tracking this down is to record what characters
|
|
|
898 Emacs is sending to the terminal. Execute the Lisp expression
|
|
120
|
899 (open-termscript "./emacs-script") to make Emacs write all terminal
|
|
|
900 output into the file ~/emacs-script as well; then do what makes the
|
|
|
901 screen update wrong, and look at the file and decode the characters
|
|
|
902 using the manual for the terminal. There are several possibilities:
|
|
0
|
903
|
|
|
904 1) The characters sent are correct, according to the terminal manual.
|
|
|
905
|
|
|
906 In this case, there is no obvious bug in Emacs, and most likely you
|
|
|
907 need more padding, or possibly the terminal manual is wrong.
|
|
|
908
|
|
120
|
909 2) The characters sent are incorrect, due to an obscure aspect of the
|
|
|
910 terminal behavior not described in an obvious way by termcap.
|
|
0
|
911
|
|
120
|
912 This case is hard. It will be necessary to think of a way for Emacs
|
|
|
913 to distinguish between terminals with this kind of behavior and other
|
|
|
914 terminals that behave subtly differently but are classified the same
|
|
|
915 by termcap; or else find an algorithm for Emacs to use that avoids the
|
|
|
916 difference. Such changes must be tested on many kinds of terminals.

936 *** A position you specified in .Xdefaults is ignored, using twm.
|
|
|
937
|
|
|
938 twm normally ignores "program-specified" positions.
|
|
|
939 You can tell it to obey them with this command in your `.twmrc' file:
|
|
|
940
|
|
|
941 UsePPosition "on" #allow clents to request a position
|

943 *** With M-x enable-flow-control, you need to type C-\ twice to do
|
|
|
944 incremental search--a single C-\ gets no response.
|
|
|
945
|
|
|
946 This has been traced to communicating with your machine via kermit,
|
|
|
947 with C-\ as the kermit escape character. One solution is to use
|
|
|
948 another escape character in kermit. One user did
|
|
|
949
|
|
|
950 set escape-character 17
|
|
|
951
|
|
|
952 in his .kermrc file, to make C-q the kermit escape character.

954 *** The Motif version of Emacs paints the screen a solid color.
|
|
|
955
|
|
|
956 This has been observed to result from the following X resource:
|
|
|
957
|
|
|
958 Emacs*default.attributeFont: -*-courier-medium-r-*-*-*-140-*-*-*-*-iso8859-*
|
|
|
959
|
|
|
960 That the resource has this effect indicates a bug in something, but we
|
|
|
961 do not yet know what. If it is an Emacs bug, we hope someone can
|
|
|
962 explain what the bug is so we can fix it. In the mean time, removing
|
|
|
963 the resource prevents the problem.
|
|
|
964
|
|
|
965 *** After running emacs once, subsequent invocations crash.
|
|
|
966
|
|
|
967 Some versions of SVR4 have a serious bug in the implementation of the
|
|
|
968 mmap () system call in the kernel; this causes emacs to run correctly
|
|
|
969 the first time, and then crash when run a second time.
|
|
|
970
|
|
|
971 Contact your vendor and ask for the mmap bug fix; in the mean time,
|
|
|
972 you may be able to work around the problem by adding a line to your
|
|
|
973 operating system description file (whose name is reported by the
|
|
|
974 configure script) that reads:
|
|
|
975 #define SYSTEM_MALLOC
|
|
|
976 This makes Emacs use memory less efficiently, but seems to work around
|
|
|
977 the kernel bug.

|
|
978
|
|
|
979 *** Inability to send an Alt-modified key, when Emacs is communicating
|
|
|
980 directly with an X server.
|
|
|
981
|
|
|
982 If you have tried to bind an Alt-modified key as a command, and it
|
|
|
983 does not work to type the command, the first thing you should check is
|
|
|
984 whether the key is getting through to Emacs. To do this, type C-h c
|
|
|
985 followed by the Alt-modified key. C-h c should say what kind of event
|
|
|
986 it read. If it says it read an Alt-modified key, then make sure you
|
|
|
987 have made the key binding correctly.
|
|
|
988
|
|
|
989 If C-h c reports an event that doesn't have the Alt modifier, it may
|
|
|
990 be because your X server has no key for the Alt modifier. The X
|
|
|
991 server that comes from MIT does not set up the Alt modifier by
|
|
|
992 default.
|
|
|
993
|
|
|
994 If your keyboard has keys named Alt, you can enable them as follows:
|
|
|
995
|
|
|
996 xmodmap -e 'add mod2 = Alt_L'
|
|
|
997 xmodmap -e 'add mod2 = Alt_R'
|
|
|
998
|
|
|
999 If the keyboard has just one key named Alt, then only one of those
|
|
|
1000 commands is needed. The modifier `mod2' is a reasonable choice if you
|
|
|
1001 are using an unmodified MIT version of X. Otherwise, choose any
|
|
|
1002 modifier bit not otherwise used.
|
|
|
1003
|
|
|
1004 If your keyboard does not have keys named Alt, you can use some other
|
|
|
1005 keys. Use the keysym command in xmodmap to turn a function key (or
|
|
|
1006 some other 'spare' key) into Alt_L or into Alt_R, and then use the
|
|
|
1007 commands show above to make them modifier keys.
|
|
|
1008
|
|
|
1009 Note that if you have Alt keys but no Meta keys, Emacs translates Alt
|
|
|
1010 into Meta. This is because of the great importance of Meta in Emacs.
|
|
|
1011
|
|
|
1012 *** In Shell mode, you get a ^M at the end of every line.
|
|
|
1013
|
|
|
1014 This happens to people who use tcsh, because it is trying to be too
|
|
|
1015 smart. It sees that the Shell uses terminal type `unknown' and turns
|
|
|
1016 on the flag to output ^M at the end of each line. You can fix the
|
|
|
1017 problem by adding this to your .cshrc file:
|
|
|
1018
|
|
|
1019 if ($?EMACS) then
|
|
|
1020 if ($EMACS == "t") then
|
|
|
1021 unset edit
|
|
|
1022 stty -icrnl -onlcr -echo susp ^Z

|

1028

1029 This comes from having an invalid X resource, such as
|
|
|
1030 emacs*Cursor: black
|
|
|
1031 (which is invalid because it specifies a color name for something

1036 *** Once you pull down a menu from the menubar, it won't go away.
|
|
|
1037
|
|
|
1038 It has been claimed that this is caused by a bug in certain very old
|
|
|
1039 (1990?) versions of the twm window manager. It doesn't happen with
|
|
|
1040 recent vintages, or with other window managers.

1042 *** Emacs ignores the "help" key when running OLWM.
|
|
|
1043
|
|
|
1044 OLWM grabs the help key, and retransmits it to the appropriate client
|
|
|
1045 using XSendEvent. Allowing emacs to react to synthetic events is a
|
|
|
1046 security hole, so this is turned off by default. You can enable it by
|
|
|
1047 setting the variable x-allow-sendevents to t. You can also cause fix
|
|
|
1048 this by telling OLWM to not grab the help key, with the null binding
|
|
|
1049 "OpenWindows.KeyboardCommand.Help:".

1051 *** Programs running under terminal emulator do not recognize `emacs'
|
|
|
1052 terminal type.
|
|
|
1053
|
|
|
1054 The cause of this is a shell startup file that sets the TERMCAP
|
|
|
1055 environment variable. The terminal emulator uses that variable to
|
|
|
1056 provide the information on the special terminal type that Emacs
|
|
|
1057 emulates.
|
|
|
1058
|
|
|
1059 Rewrite your shell startup file so that it does not change TERMCAP
|
|
|
1060 in such a case. You could use the following conditional which sets
|
|
|
1061 it only if it is undefined.
|
|
|
1062
|
|
|
1063 if ( ! ${?TERMCAP} ) setenv TERMCAP ~/my-termcap-file
|
|
|
1064
|
|
|
1065 Or you could set TERMCAP only when you set TERM--which should not
|
|
|
1066 happen in a non-login shell.

|

1134 you have probably compiled using an ANSI C compiler, but with non-ANSI
|
|
|
1135 include files. In particular, on Suns, the file
|
|
|
1136 /usr/include/sun/audioio.h uses the _IOW macro to define the constant
|
|
|
1137 AUDIOSETQSIZE. _IOW in turn uses a K&R preprocessor feature that is
|
|
|
1138 now explicitly forbidden in ANSI preprocessors, namely substitution
|
|
|
1139 inside character constants. All ANSI C compilers must provide a
|
|
|
1140 workaround for this problem. Lucid's C compiler is shipped with a new
|
|
|
1141 set of system include files. If you are using GCC, there is a script
|
|
|
1142 called fixincludes that creates new versions of some system include
|

1143 files that use this obsolete feature.

1178 Be sure also to edit x/config/cf/sun.cf so that OSMinorVersion is 4

1179 (as it should be for Solaris 2.4). The file has three definitions for
|

1210
|
|
124
|
1211 Many emacs mail user agents (VM and rmail, for instance) use the
|
|
|
1212 sendmail.el library. This library can arrange for mail to be
|
|
|
1213 delivered by passing messages to the /usr/lib/sendmail (usually)
|
|
|
1214 program . In doing so, it passes the '-t' flag to sendmail, which
|
|
|
1215 means that the name of the recipient of the message is not on the
|
|
|
1216 command line and, therefore, that sendmail must parse the message to
|
|
|
1217 obtain the destination address.

1218
|
|
|
1219 There is a bug in the SunOS4.1.1 and SunOS4.1.3 versions of sendmail.
|
|
|
1220 In short, when given the -t flag, the SunOS sendmail won't recognize
|
|

1221 non-local (i.e. NIS) aliases. It has been reported that the Solaris

1222 2.x versions of sendmail do not have this bug. For those using SunOS
|
|
|
1223 4.1, the best fix is to install sendmail V8 or IDA sendmail (which
|
|
|
1224 have other advantages over the regular sendmail as well). At the time

1225 of this writing, these official versions are available:

1242 libraries. The cause is that the site has installed a version of the
|
|
|
1243 shared library which uses a name server--but has not installed a
|
|
|
1244 similar version of the unshared library which Emacs uses.
|
|
0
|
1245
|
|
124
|
1246 The result is that most programs, using the shared library, work with
|
|
|
1247 the nameserver, but Emacs does not.
|
|
|
1248
|
|
|
1249 The fix is to install an unshared library that corresponds to what you
|
|
|
1250 installed in the shared library, and then relink Emacs.

|
1252 On SunOS 4.1, simply define HAVE_RES_INIT.
|
|
|
1253
|
|
|
1254 If you have already installed the name resolver in the file libresolv.a,
|
|
|
1255 then you need to compile Emacs to use that library. The easiest way to
|
|
|
1256 do this is to add to config.h a definition of LIBS_SYSTEM, LIBS_MACHINE
|
|
|
1257 or LIB_STANDARD which uses -lresolv. Watch out! If you redefine a macro
|
|
|
1258 that is already in use in your configuration to supply some other libraries,
|
|
|
1259 be careful not to lose the others.
|
|
|
1260
|
|
|
1261 Thus, you could start by adding this to config.h:
|
|
|
1262
|
|
|
1263 #define LIBS_SYSTEM -lresolv
|
|
|
1264
|
|
|
1265 Then if this gives you an error for redefining a macro, and you see that
|
|
|
1266 the s- file defines LIBS_SYSTEM as -lfoo -lbar, you could change config.h
|
|
|
1267 again to say this:
|
|
|
1268
|
|
|
1269 #define LIBS_SYSTEM -lresolv -lfoo -lbar

1271 *** With process-connection-type set to t, each line of subprocess

|
|
|
1273
|
|
|
1274 On SunOS systems, this problem has been seen to be a result of an
|
|
|
1275 incomplete installation of gcc 2.2 which allowed some non-ANSI
|
|
|
1276 compatible include files into the compilation. In particular this
|
|
|
1277 affected virtually all ioctl() calls.

1280 ** Linux
|
|
367
|
1281 *** Mandrake
|
|
|
1282
|
|
|
1283 The Mandrake Linux distribution is attempting to comprehensively
|
|
|
1284 update the user interface, and make it consistent across
|
|
|
1285 applications. This is very difficult, and will occasionally cause
|
|
|
1286 conflicts with applications like Emacs with their own long-established
|
|
|
1287 interfaces. Known issues specific to Mandrake or especially common:
|
|
|
1288
|
|
|
1289 Some versions of XEmacs distributed with Mandrake were patched to make
|
|
|
1290 the Meta and Alt keysyms synonymous. These normally work as expected
|
|
|
1291 in the Mandrake environment. However, custom-built XEmacsen will seem
|
|
|
1292 to "inexplicably" not respect the "Alt-invokes-Meta-commands" convention.
|
|
|
1293 See "I want XEmacs to use the Alt key" below.
|
|
|
1294
|
|
|
1295 The color-gcc wrapper (see below) is in common use on the Mandrake
|
|
|
1296 platform.
|
|
|
1297
|
|
|
1298 *** I want XEmacs to use the Alt key, not the XXX key, for Meta commands
|
|
|
1299
|
|
|
1300 For historical reasons, XEmacs looks for a Meta key, then an Alt key.
|
|
|
1301 It binds Meta commands to the X11 modifier bit attached to the first
|
|
|
1302 of these it finds. On PCs, the Windows key is often assigned the Meta
|
|
|
1303 bit, but many desktop environments go to great lengths to get all apps
|
|
|
1304 to use the Alt key, and reserve the Windows key to (sensibly enough)
|
|
|
1305 the window manager.
|
|
|
1306
|
|
|
1307 One correct way to implement this was suggested on comp.emacs.xemacs
|
|
|
1308 (by Kilian Foth and in more detail by Michael Piotrowski): unmap the
|
|
|
1309 Meta modifier using xmodmap or xkb, and then map the Meta/Windows key
|
|
|
1310 to the Super or Hyper keysym and an appropriate mod bit. XEmacs will
|
|
|
1311 not find the Meta keysym, and default to using the Alt key for Meta
|
|
|
1312 keybindings. Typically few applications use the (X11) Meta modifier;
|
|
|
1313 it is tedious but not too much so to teach the ones you need to use
|
|
|
1314 Super instead of Meta. There may be further useful hints in the
|
|
|
1315 discussion of keymapping on non-Linux platforms.
|
|
|
1316
|
|
|
1317 *** The color-gcc wrapper
|
|
|
1318
|
|
|
1319 This wrapper colorizes the error messages from gcc. By default XEmacs
|
|
|
1320 does not interpret the escape sequences used to generate colors,
|
|
|
1321 resulting in a cluttered, hard-to-read buffer. You can remove or
|
|
|
1322 defeat the wrapper, or you may get good results from the ansi-color.el
|
|
|
1323 library:

|
1327 *** `C-z', or `M-x suspend-emacs' hangs instead of suspending.
|
|
|
1328
|
|
|
1329 If you build with `gpm' support on Linux, you cannot suspend XEmacs
|
|
|
1330 because gpm installs a buggy SIGTSTP handler. Either compile with
|
|
|
1331 `--with-gpm=no', or don't suspend XEmacs on the Linux console until
|
|
|
1332 this bug is fixed.

1334 *** With certain fonts, when the cursor appears on a character, the
|
|
|
1335 character doesn't appear--you get a solid box instead.
|
|
|
1336
|
|
|
1337 One user on a Linux system reported that this problem went away with
|
|
|
1338 installation of a new X server. The failing server was XFree86 3.1.1.
|
|
|
1339 XFree86 3.1.2 works.
|
|
|
1340
|
|
|
1341 *** Slow startup on Linux.
|
|
|
1342
|
|
|
1343 People using systems based on the Linux kernel sometimes report that
|
|
|
1344 startup takes 10 to 15 seconds longer than `usual'.
|
|
|
1345
|
|
|
1346 This is because Emacs looks up the host name when it starts.
|
|
|
1347 Normally, this takes negligible time; the extra delay is due to
|
|
|
1348 improper system configuration. This problem can occur for both
|
|
|
1349 networked and non-networked machines.
|
|
|
1350
|
|
|
1351 Here is how to fix the configuration. It requires being root.
|
|
|
1352
|
|
|
1353 **** Networked Case
|
|
|
1354
|
|
|
1355 First, make sure the files `/etc/hosts' and `/etc/host.conf' both
|
|
|
1356 exist. The first line in the `/etc/hosts' file should look like this
|
|
|
1357 (replace HOSTNAME with your host name):
|
|
|
1358
|
|
|
1359 127.0.0.1 localhost HOSTNAME
|
|
|
1360
|
|
|
1361 Also make sure that the `/etc/host.conf' files contains the following
|
|
|
1362 lines:
|
|
|
1363
|
|
|
1364 order hosts, bind
|
|
|
1365 multi on
|
|
|
1366
|
|
|
1367 Any changes, permanent and temporary, to the host name should be
|
|
|
1368 indicated in the `/etc/hosts' file, since it acts a limited local
|
|
|
1369 database of addresses and names (e.g., some SLIP connections
|
|
|
1370 dynamically allocate ip addresses).
|
|
|
1371
|
|
|
1372 **** Non-Networked Case
|
|
|
1373
|
|
|
1374 The solution described in the networked case applies here as well.
|
|
|
1375 However, if you never intend to network your machine, you can use a
|
|
|
1376 simpler solution: create an empty `/etc/host.conf' file. The command
|
|
|
1377 `touch /etc/host.conf' suffices to create the file. The `/etc/hosts'
|
|
|
1378 file is not necessary with this approach.
|
|
|
1379
|
|
|
1380
|
|
|
1381 ** IRIX
|
|
|
1382 *** On Irix, I don't see the toolbar icons and I'm getting lots of
|
|
|
1383 entries in the warnings buffer.
|
|
|
1384
|
|
|
1385 SGI ships a really old Xpm library in /usr/lib which does not work at
|
|
|
1386 all well with XEmacs. The solution is to install your own copy of the
|
|
|
1387 latest version of Xpm somewhere and then use the --site-includes and
|
|
|
1388 --site-libraries flags to tell configure where to find it.
|
|
|
1389
|
|
|
1390 *** Trouble using ptys on IRIX, or running out of ptys.
|
|
|
1391
|
|
|
1392 The program mkpts (which may be in `/usr/adm' or `/usr/sbin') needs to
|
|
|
1393 be set-UID to root, or non-root programs like Emacs will not be able
|
|
|
1394 to allocate ptys reliably.
|
|
|
1395
|
|
|
1396 *** Motif dialog boxes lose on Irix.

|

1414 *** XEmacs crashes on Digital Unix within font-lock, or when dealing
|
|
|
1415 with large compilation buffers.
|
|
|
1416
|
|
|
1417 The default stack size under Digital Unix is rather small (2M as
|
|
|
1418 opposed to Solaris 8M), hosing the regexp code, which uses alloca()
|
|
|
1419 extensively, overflowing the stack when complex regexps are used.
|
|
|

|
|
0
|
1421
|
|
312
|
1422 1) Increase your stack size, using `ulimit -s 8192' or a (t)csh
|
|
|
1423 equivalent;
|
|
|
1424

|
|
1425 2) Recompile regex.c with REGEX_MALLOC defined.

|
|
1427 *** The `Alt' key doesn't behave as `Meta' when running DECwindows.
|
|
|
1428
|
|
|
1429 The default DEC keyboard mapping has the Alt keys set up to generate the
|
|
|
1430 keysym `Multi_key', which has a meaning to xemacs which is distinct from that
|
|
|
1431 of the `Meta_L' and `Meta-R' keysyms. A second problem is that certain keys
|
|
|
1432 have the Mod2 modifier attached to them for no adequately explored reason.
|
|
|
1433 The correct fix is to pass this file to xmodmap upon starting X:
|
|
|
1434
|
|
|
1435 clear mod2
|
|
|
1436 keysym Multi_key = Alt_L
|
|
|
1437 add mod1 = Alt_L
|
|
|
1438 add mod1 = Alt_R

|
|
1440 *** The Compose key on a DEC keyboard does not work as Meta key.

1444 xmodmap -e 'keycode 0xb1 = Meta_L'

1445

1446 *** `expand-file-name' fails to work on any but the machine you dumped
|
|
|
1447 Emacs on.
|
|
|
1448
|
|
|
1449 On Ultrix, if you use any of the functions which look up information
|
|
|
1450 in the passwd database before dumping Emacs (say, by using
|
|
|
1451 expand-file-name in site-init.el), then those functions will not work
|
|
|
1452 in the dumped Emacs on any host but the one Emacs was dumped on.
|
|
|
1453
|
|
|
1454 The solution? Don't use expand-file-name in site-init.el, or in
|
|
|
1455 anything it loads. Yuck - some solution.
|
|
|
1456
|
|
|
1457 I'm not sure why this happens; if you can find out exactly what is
|
|
|
1458 going on, and perhaps find a fix or a workaround, please let us know.
|
|
|
1459 Perhaps the YP functions cache some information, the cache is included
|
|
|
1460 in the dumped Emacs, and is then inaccurate on any other host.

1463 ** HP-UX

1464 *** I get complaints about the mapping of my HP keyboard at startup,
|
|
|
1465 but I haven't changed anything.
|
|
|
1466
|
|
|
1467 The default HP keymap is set up to have Mod1 assigned to two different keys:
|
|
|
1468 Meta_L and Mode_switch (even though there is not actually a Mode_switch key on
|
|
|
1469 the keyboard -- it uses an "imaginary" keycode.) There actually is a reason
|
|
|
1470 for this, but it's not a good one. The correct fix is to execute this command
|
|
|
1471 upon starting X:
|
|
|
1472
|
|
|
1473 xmodmap -e 'remove mod1 = Mode_switch'

1518 *** XEmacs dumps core at startup when native audio is used. Native
|
|
|
1519 audio does not work with recent versions of HP-UX.
|
|
|
1520
|
|
|
1521 Under HP-UX 10.20 and later (e.g., HP-UX 11.XX), with native audio
|
|
|
1522 enabled, the dumped XEmacs binary ("xemacs") core dumps at startup if
|
|
|
1523 recent versions of the libAlib.sl audio shared library is used. Note
|
|
|
1524 that "temacs" will run, but "xemacs" will dump core. This, of course,
|
|
|
1525 causes the XEmacs build to fail. If GNU malloc is enabled, a stack
|
|
|
1526 trace will show XEmacs to have crashed in the "first" call to malloc().
|
|
|
1527
|
|
|
1528 This bug currently exists in all versions of XEmacs, when the undump
|
|
|
1529 mechanism is used. It is not known if using the experimental portable
|
|
|
1530 dumper will allow native audio to work.
|
|
|
1531
|
|
|
1532 **** Cause:
|
|
|
1533
|
|
|
1534 Recent versions of the HP-UX 10.20 (and later) audio shared library (in
|
|
|
1535 /opt/audio/lib), pulls in the libdce shared library, which pulls in a
|
|
|
1536 thread (libcma) library. This prevents the HP-UX undump() routine (in
|
|
|
1537 unexhp9k800.c) from properly working. What's happening is that some
|
|
|
1538 initialization routines are being called in the libcma library, *BEFORE*
|
|
|
1539 main() is called, and these initialization routines are calling
|
|
|
1540 malloc(). Unfortunately, in order for the undumper to work, XEmacs must
|
|
|
1541 adjust (move upwards) the sbrk() value *BEFORE* the first call to
|
|
|
1542 malloc(); if malloc() is called before XEmacs has properly adjusted sbrk
|
|
|
1543 (which is what is happening), dumped memory that is being used by
|
|
|
1544 XEmacs, is improperly re-allocated for use by malloc() and the dumped
|
|
|
1545 memory is corrupted. This causes XEmacs to die an horrible death.
|
|
|
1546
|
|
|
1547 It is believed that versions of the audio library past December 1998
|
|
|
1548 will trigger this problem. Under HP-UX 10.20, you probably have to
|
|
|
1549 install audio library patches to encounter this. It's probable that
|
|
|
1550 recent "fresh, out-of-the-box" HP-UX 11.XX workstations also have this
|
|
|
1551 problem. For HP-UX 10.20, it's believed that audio patch PHSS_17121 (or
|
|
|
1552 a superceeding one, like PHSS_17554, PHSS_17971, PHSS_18777, PHSS_21481,
|
|
|

|
|
1555 To check if your audio library will cause problems for XEmacs, run
|
|
|
1556 "chatr /opt/audio/lib/libAlib.sl". If "libdce" appears in the displayed
|
|
|
1557 shared library list, XEmacs will probably encounter problems if audio is
|
|
|
1558 enabled.
|
|
|
1559
|
|
|
1560 **** Workaround:
|
|
|
1561
|
|
|
1562 Don't enable native audio. Re-run configure without native audio
|
|
|
1563 support.

|
1565 If your site supports it, try using NAS (Network Audio Support).

|
|
1568 not.

1571 *** `Pid xxx killed due to text modification or page I/O error'
|
|
|
1572
|
|
|
1573 On HP-UX, you can get that error when the Emacs executable is on an NFS
|
|
|
1574 file system. HP-UX responds this way if it tries to swap in a page and
|
|
|
1575 does not get a response from the server within a timeout whose default
|
|
|
1576 value is just ten seconds.
|
|
|
1577
|
|
|
1578 If this happens to you, extend the timeout period.

1582 christos@theory.tn.cornell.edu says:
|
|
|
1583
|
|
|
1584 The problem is that in your .cshrc you have something that tries to
|
|
197
|
1585 execute `tty`. If you are not running the shell on a real tty then tty
|
|
|
1586 will print "not a tty". Csh expects one word in some places, but tty
|
|
|
1587 is giving it back 3.
|
|
124
|
1588
|
|
197
|
1589 The solution is to add a pair of quotes around `tty` to make it a
|
|
|
1590 single word:
|
|
0
|
1591
|
|
124
|
1592 if (`tty` == "/dev/console")
|
|
|
1593
|
|
|
1594 should be changed to:
|
|
|
1595
|
|
|
1596 if ("`tty`" == "/dev/console")
|
|
|
1597
|
|
|
1598 Even better, move things that set up terminal sections out of .cshrc
|
|
|
1599 and into .login.

1622 * Compatibility problems (with Emacs 18, GNU Emacs, or previous XEmacs/lemacs)
|

1625 *** "Symbol's value as variable is void: unread-command-char".
|

|
|
88
|
1628
|
|
124
|
1629 There are a few incompatible changes in XEmacs, and these are the
|
|
|
1630 symptoms. Some of the emacs-lisp code you are running needs to be
|
|
|
1631 updated to be compatible with XEmacs.
|
|
|
1632
|
|
|
1633 The code should not treat keymaps as arrays (use `define-key', etc.),
|
|
|
1634 should not use obsolete variables like `unread-command-char' (use
|
|
197
|
1635 `unread-command-events'). Many (most) of the new ways of doing things
|
|
124
|
1636 are compatible in GNU Emacs and XEmacs.
|
|
88
|
1637
|
|
197
|
1638 Modern Emacs packages (Gnus, VM, W3, efs, etc) are written to support
|
|
|
1639 GNU Emacs and XEmacs. We have provided modified versions of several
|
|
|
1640 popular emacs packages (dired, etc) which are compatible with this
|
|
|
1641 version of emacs. Check to make sure you have not set your load-path
|
|
|
1642 so that your private copies of these packages are being found before
|
|
|
1643 the versions in the lisp directory.
|
|
124
|
1644
|
|
|
1645 Make sure that your load-path and your $EMACSLOADPATH environment
|
|
|
1646 variable are not pointing at an Emacs18 lisp directory. This will
|
|
|
1647 cripple emacs.

|
|
124
|
1651
|
|
197
|
1652 Code which uses the `face' accessor functions must be recompiled with
|
|
|
1653 xemacs 19.9 or later. The functions whose callers must be recompiled
|
|
|
1654 are: face-font, face-foreground, face-background,
|
|
|
1655 face-background-pixmap, and face-underline-p. The .elc files
|
|
|
1656 generated by version 19.9 will work in 19.6 and 19.8, but older .elc
|
|
|
1657 files which contain calls to these functions will not work in 19.9.

1661 This error is given when XEmacs 20 is compiled without MULE support
|

1672 * MULE issues
|
|
197
|
1673 =============
|
|
144
|
1674
|
|
223
|
1675 ** A reminder: XEmacs/Mule work does not currently receive *any*
|
|
|
1676 funding, and all work is done by volunteers. If you think you can
|
|
|
1677 help, please contact the XEmacs maintainers.
|
|
|
1678
|
|
278
|
1679 ** XEmacs/Mule doesn't support TTY's satisfactorily.
|
|
223
|
1680
|
|
|
1681 This is a major problem, which we plan to address in a future release
|
|
|
1682 of XEmacs. Basically, XEmacs should have primitives to be told
|
|
|
1683 whether the terminal can handle international output, and which
|
|
|
1684 locale. Also, it should be able to do approximations of characters to
|
|
|
1685 the nearest supported by the locale.
|
|
|
1686
|
|
197
|
1687 ** Internationalized (Asian) Isearch doesn't work.
|
|
144
|
1688
|
|
|
1689 Currently, Isearch doesn't directly support any of the input methods
|
|
|
1690 that are not XIM based (like egg, canna and quail) (and there are
|
|
223
|
1691 potential problems with XIM version too...). If you're using egg
|
|
|
1692 there is a workaround. Hitting <RET> right after C-s to invoke
|
|
|
1693 Isearch will put Isearch in string mode, where a complete string can
|
|
|
1694 be typed into the minibuffer and then processed by Isearch afterwards.
|
|
|
1695 Since egg is now supported in the minibuffer using string mode you can
|
|
|
1696 now use egg to input your Japanese, Korean or Chinese string, then hit
|
|
|
1697 return to send that to Isearch and then use standard Isearch commands
|
|
|
1698 from there.
|
|
144
|
1699
|
|
223
|
1700 ** Using egg and mousing around while in 'fence' mode screws up my
|
|
|
1701 buffer.
|
|
144
|
1702
|
|
|
1703 Don't do this. The fence modes of egg and canna are currently very
|
|
|
1704 modal, and messing with where they expect point to be and what they
|
|
|
1705 think is the current buffer is just asking for trouble. If you're
|
|
|
1706 lucky they will realize that something is awry, and simply delete the
|
|
|
1707 fence, but worst case can trash other buffers too. We've tried to
|
|
|
1708 protect against this where we can, but there still are many ways to
|
|
|
1709 shoot yourself in the foot. So just finish what you are typing into
|
|
|
1710 the fence before reaching for the mouse.
|
|
223
|
1711
|
|
|
1712 ** Not all languages in Quail are supported like Devanagari and Indian
|
|
|
1713 languages, Lao and Tibetan.
|
|
|
1714
|
|
|
1715 Quail requires more work and testing. Although it has been ported to
|
|
|
1716 XEmacs, it works really well for Japanese and for the European
|
|
|
1717 languages.
|
|
|
1718
|
|
|
1719 ** Right-to-left mode is not yet implemented, so languages like
|
|
|
1720 Arabic, Hebrew and Thai don't work.
|
|
|
1721
|
|
|
1722 Getting this right requires more work. It may be implemented in a
|
|
|
1723 future XEmacs version, but don't hold your breath. If you know
|
|
|
1724 someone who is ready to implement this, please let us know.
|
|
|
1725
|
|
|
1726 ** We need more developers and native language testers. It's extremely
|
|
|
1727 difficult (and not particularly productive) to address languages that
|
|
|
1728 nobody is using and testing.
|
|
|
1729
|
|
|
1730 ** The kWnn and cWnn support for Chinese and Korean needs developers
|
|
|
1731 and testers. It probably doesn't work.
|
|
|
1732
|
|
|
1733 ** There are no `native XEmacs' TUTORIALs for any Asian languages,
|
|
|
1734 including Japanese. FSF Emacs and XEmacs tutorials are quite similar,
|
|
|
1735 so it should be sufficient to skim through the differences and apply
|
|
|
1736 them to the Japanese version.
|
|
|
1737
|
|
|
1738 ** We only have localized menus translated for Japanese, and the
|
|
|
1739 Japanese menus are developing bitrot (the Mule menu appears in
|
|
|
1740 English).
|
|
|
1741
|
|
|
1742 ** XIM is untested for any language other than Japanese.
