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
|
|
333
|
128 *** The libXt shipped with AIX 4.3 is broken. This causes xemacs -nw
|
|
|
129 to fail in various ways. The solution is to build against stock
|
|
|
130 X11R6.
|
|
|
131
|
|
312
|
132 *** On AIX, you get this compiler error message:
|
|
|
133
|
|
|
134 Processing include file ./XMenuInt.h
|
|
|
135 1501-106: (S) Include file X11/Xlib.h not found.
|
|
|
136
|
|
|
137 This means your system was installed with only the X11 runtime i.d
|
|
|
138 libraries. You have to find your sipo (bootable tape) and install
|
|
|
139 X11Dev... with smit.
|
|
|
140
|
|
|
141 *** On AIX 4.1.2, linker error messages such as
|
|
|
142 ld: 0711-212 SEVERE ERROR: Symbol .__quous, found in the global symbol table
|
|
|
143 of archive /usr/lib/libIM.a, was not defined in archive member shr.o.
|
|
|
144
|
|
|
145 This is a problem in libIM.a. You can work around it by executing
|
|
|
146 these shell commands in the src subdirectory of the directory where
|
|
|
147 you build Emacs:
|
|
|
148
|
|
|
149 cp /usr/lib/libIM.a .
|
|
|
150 chmod 664 libIM.a
|
|
|
151 ranlib libIM.a
|
|
|
152
|
|
|
153 Then change -lIM to ./libIM.a in the command to link temacs (in
|
|
|
154 Makefile).
|
|
|
155
|
|
|
156 *** Excessive optimization on AIX 4.2 can lead to compiler failure.

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

160 (3.1.4.4), there are problems with -O3. I haven't investigated
|
|
|
161 further.

163
|
|
|
164 ** SunOS/Solaris
|
|
|
165 *** Link failure when using acc on a Sun.
|
|
|
166
|
|
|
167 To use acc, you need additional options just before the libraries, such as
|
|
|
168
|
|
|
169 /usr/lang/SC2.0.1/values-Xt.o -L/usr/lang/SC2.0.1/cg87 -L/usr/lang/SC2.0.1
|
|
|
170
|
|
|
171 and you need to add -lansi just before -lc.
|
|
|
172
|
|
|
173 The precise file names depend on the compiler version, so we
|
|
|
174 cannot easily arrange to supply them.
|
|
|
175
|
|
|
176 *** Problems finding X11 libraries on Solaris with Openwindows
|
|
|
177
|
|
|
178 Some users have reported problems in this area. The reported solution
|
|
|
179 is to define the environment variable OPENWINHOME, even if you must set
|
|
|
180 it to `/usr/openwin'.
|
|
|
181
|
|
|
182 *** Sed problems on Solaris 2.5
|
|
|
183
|
|
|
184 There have been reports of Sun sed truncating very lines in the
|
|
|
185 Makefile during configuration. The workaround is to use GNU sed or,
|
|
|
186 even better, think of a better way to generate Makefile, and send us a
|
|
|
187 patch. :-)
|
|
|
188
|
|
|
189 *** On Solaris 2 I get undefined symbols from libcurses.a.
|
|
|
190
|
|
|
191 You probably have /usr/ucblib/ on your LD_LIBRARY_PATH. Do the link with
|
|
|
192 LD_LIBRARY_PATH unset. Generally, avoid using any ucb* stuff when
|
|
|
193 building XEmacs.
|
|
|
194
|
|
|
195 *** On Solaris 2 I cannot make alloc.o, glyphs.o or process.o.
|
|
|
196
|
|
|
197 The SparcWorks C compiler may have difficulty building those modules
|
|
|
198 with optimization level -xO4. Try using only "-fast" optimization
|
|
|
199 for just those modules. (Or use gcc).
|
|
|
200
|
|
|
201 *** Solaris 2.3 /bin/sh coredumps during configuration.
|
|
|
202
|
|
|
203 This only occurs if you have LANG != C. This is a known bug with
|
|
|
204 /bin/sh fixed by installing Patch-ID# 101613-01. Or, you can use
|
|
|
205 bash, as a workaround.
|
|
|
206
|
|
|
207 *** On SunOS, you get linker errors
|
|
|
208 ld: Undefined symbol
|
|
|
209 _get_wmShellWidgetClass
|
|
|
210 _get_applicationShellWidgetClass
|
|
|
211
|
|
|
212 The fix to this is to install patch 100573 for OpenWindows 3.0
|
|
|
213 or link libXmu statically.
|
|
|
214
|
|
|
215 *** On Sunos 4, you get the error ld: Undefined symbol __lib_version.
|
|
|
216
|
|
|
217 This is the result of using cc or gcc with the shared library meant
|
|
|
218 for acc (the Sunpro compiler). Check your LD_LIBRARY_PATH and delete
|
|
|
219 /usr/lang/SC2.0.1 or some similar directory.
|
|
|
220
|
|
|
221 *** Undefined symbols when linking on Sunos 4.1.
|
|
|
222
|
|
|
223 If you get the undefined symbols _atowc _wcslen, _iswprint, _iswspace,
|
|
|
224 _iswcntrl, _wcscpy, and _wcsncpy, then you need to add -lXwchar after
|
|
|
225 -lXaw in the command that links temacs.
|
|
|
226
|
|
|
227 This problem seems to arise only when the international language
|
|
|
228 extensions to X11R5 are installed.
|
|
|
229
|
|
|
230 *** On a Sun running SunOS 4.1.1, you get this error message from GNU ld:
|
|
|
231
|
|
|
232 /lib/libc.a(_Q_sub.o): Undefined symbol __Q_get_rp_rd referenced from text segment
|
|
|
233
|
|
|
234 The problem is in the Sun shared C library, not in GNU ld.
|
|
|
235
|
|
|
236 The solution is to install Patch-ID# 100267-03 from Sun.
|
|
|
237
|
|
|
238 *** SunOS 4.1.2: undefined symbol _get_wmShellWidgetClass
|
|
|
239
|
|
|
240 Apparently the version of libXmu.so.a that Sun ships is hosed: it's missing
|
|
|
241 some stuff that is in libXmu.a (the static version). Sun has a patch for
|
|
|
242 this, but a workaround is to use the static version of libXmu, by changing
|
|
|
243 the link command from "-lXmu" to "-Bstatic -lXmu -Bdynamic". If you have
|
|
|
244 OpenWindows 3.0, ask Sun for these patches:
|
|
|
245 100512-02 4.1.x OpenWindows 3.0 libXt Jumbo patch
|
|
|
246 100573-03 4.1.x OpenWindows 3.0 undefined symbols with shared libXmu
|
|
|
247
|
|
|
248 *** Random other SunOS 4.1.[12] link errors.
|
|
|
249
|
|
|
250 The X headers and libraries that Sun ships in /usr/{include,lib}/X11 are
|
|
|
251 broken. Use the ones in /usr/openwin/{include,lib} instead.
|
|
|
252
|
|
|
253 ** Linux
|
|
|
254 *** Under Linux, you get "too many arguments to function `getpgrp'".
|
|
|
255
|
|
|
256 You have probably installed LessTiff under `/usr/local' and `libXm.so'
|
|
|
257 could not be found when linking `getpgrp()' test program, making XEmacs
|
|
|
258 think that `getpgrp()' takes an argument. Try adding `/usr/local/lib'
|
|
|
259 in `/etc/ld.so.conf' and run `ldconfig'. Then run XEmacs's `configure'
|
|
|
260 again. As with all problems of this type, reading the config.log file
|
|
|
261 generated from configure and seeing the log of how the test failed can
|
|
|
262 prove enlightening.
|
|
|
263
|
|
|
264 *** `Error: No ExtNode to pop!' on Linux systems with Lesstif.
|
|
197
|
265
|
|
|
266 This error message has been observed with lesstif-0.75a. It does not
|
|
|
267 appear to cause any harm.

312
|
269 *** xemacs: can't resolve symbol '__malloc_hook'
|
|
|
270
|
|
|
271 This is a Linux problem where you've compiled the XEmacs binary on a libc
|
|
|
272 5.4 with version higher than 5.4.19 and attempted to run the binary against
|
|
|
273 an earlier version. The solution is to upgrade your old library.

275 ** IRIX
|
|
|
276 *** Linking with -rpath on IRIX.

278 Darrell Kindred <dkindred@cmu.edu> writes:
|
|
|
279 There are a couple of problems [with use of -rpath with Irix ld], though:
|
|
|
280
|
|
|
281 1. The ld in IRIX 5.3 ignores all but the last -rpath
|
|
|
282 spec, so the patched configure spits out a warning
|
|
|
283 if --x-libraries or --site-runtime-libraries are
|
|
|
284 specified under irix 5.x, and it only adds -rpath
|
|
|
285 entries for the --site-runtime-libraries. This bug was
|
|
|
286 fixed sometime between 5.3 and 6.2.
|
|
|
287
|
|
|
288 2. IRIX gcc 2.7.2 doesn't accept -rpath directly, so
|
|
|
289 it would have to be prefixed by -Xlinker or "-Wl,".
|
|
|
290 This would be fine, except that configure compiles with
|
|
|
291 ${CC-cc} $CFLAGS $LDFLAGS ...
|
|
|
292 rather than quoting $LDFLAGS with prefix-args, like
|
|
|
293 src/Makefile does. So if you specify --x-libraries
|
|
|
294 or --site-runtime-libraries, you must use --use-gcc=no,
|
|
|
295 or configure will fail.

|

207
|
298

303
|
|
|
304 A compiler bug inserts spaces into the string "unexelfsgi . o"
|
|
|
305 in src/Makefile. Edit src/Makefile, after configure is run,
|
|
|
306 find that string, and take out the spaces.
|
|
|
307
|
|
|
308 Compiler fixes in Irix 6.0.1 should eliminate this problem.

311
|
|
312
|
312 The file cmplrs/stsupport.h was included in the wrong file set in the
|
|
|
313 Irix 5.2 distribution. You can find it in the optional fileset
|
|
|
314 compiler_dev, or copy it from some other Irix 5.2 system. A kludgy
|
|
|
315 workaround is to change unexelfsgi.c to include sym.h instead of
|
|
|
316 syms.h.

321 A problem noted by myself and others (I've lost the references) was
|
|
|
322 that XEmacs coredumped when the cut or copy toolbar buttons were
|
|
|
323 pressed. This has been fixed by loading the SGI patchset (Feb 98)
|
|
|
324 without having to recompile XEmacs.
|
|
124
|
325
|
|
312
|
326 My versions are XEmacs 20.3 (problem first noted in 19.15) and IRIX
|
|
|
327 6.2, compiled using -n32. I'd guess that the relevant individual
|
|
|
328 patch was "SG0002580: multiple fixes for X libraries". SGI recommends
|
|
|
329 that the complete patch set be installed rather than parts of it.

332 *** On Digital UNIX, the DEC C compiler might have a problem compiling
|
|
197
|
333 some files.
|
|
124
|
334
|
|
|
335 In particular, src/extents.c and src/faces.c might cause the DEC C
|
|
|
336 compiler to abort. When this happens: cd src, compile the files by
|
|
|
337 hand, cd .., and redo the "make" command. When recompiling the files by
|
|
|
338 hand, use the old C compiler for the following versions of Digital UNIX:
|
|
|
339 - V3.n: Remove "-migrate" from the compile command.
|
|
|
340 - V4.n: Add "-oldc" to the compile command.
|
|
|
341
|
|
197
|
342 A related compiler bug has been fixed by the DEC compiler team. The
|
|
|
343 new versions of the compiler should run fine.

|
346 optimization but will crash randomly if built with optimization.
|
|
|
347
|
|
|
348 Using 'cc -g' is not sufficient to eliminate all optimization. Try
|
|
|
349 'cc -g -O0' instead.

353 Sorry, XEmacs does not work under VMS. You might consider working on

354 the port if you really want to have XEmacs work under VMS.

395 Unfortunately, XEmacs releases prior to 21.0 don't work with

402 configure:
|
|
|

404 --x-libraries="/usr/lib/Motif1.2_R6 -L/usr/lib/X11R6"
|

422 ** SCO OpenServer
|
|
|
423 *** Native cc on SCO OpenServer 5 is now OK. Icc may still throw you
|
|
197
|
424 a curve. Here is what Robert Lipe <robertl@arnet.com> says:
|
|
124
|
425
|
|
|
426 Unlike XEmacs 19.13, building with the native cc on SCO OpenServer 5
|
|
|
427 now produces a functional binary. I will typically build this
|
|
|
428 configuration for COFF with:
|
|
|
429
|
|
197
|
430 /path_to_xemacs_source/configure --with-gcc=no \
|
|
124
|
431 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
432 --with-xpm --with-xface --with-sound=nas
|
|
|
433
|
|
|
434 This version now supports ELF builds. I highly recommend this to
|
|
|
435 reduce the in-core footprint of XEmacs. This is now how I compile
|
|
|
436 all my test releases. Build it like this:
|
|
|
437
|
|
|
438 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
|
439 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
440 --with-xpm --with-xface --with-sound=nas --dynamic
|
|
|
441
|
|
|
442 The compiler known as icc [ supplied with the OpenServer 5 Development
|
|
|
443 System ] generates a working binary, but it takes forever to generate
|
|
|
444 XEmacs. ICC also whines more about the code than /bin/cc does. I do
|
|
|
445 believe all its whining is legitimate, however. Note that you do
|
|
|
446 have to 'cd src ; make LD=icc' to avoid linker errors.
|
|
|
447
|
|
|
448 The way I handle the build procedure is:
|
|
|
449
|
|
|
450 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
|
451 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
452 --with-xpm --with-xface --with-sound=nas --dynamic --compiler="icc"
|
|
|
453
|
|
|
454 NOTE I have the xpm, xface, and audio libraries and includes in
|
|
|
455 /usr/local/lib, /usr/local/include. If you don't have these,
|
|
|
456 don't include the "--with-*" arguments in any of my examples.
|
|
|
457
|
|
|
458 In previous versions of XEmacs, you had to override the defaults while
|
|
|
459 compiling font-lock.o and extents.o when building with icc. This seems
|
|
|
460 to no longer be true, but I'm including this old information in case it
|
|
|
461 resurfaces. The process I used was:
|
|
|
462
|
|
|
463 make -k
|
|
|
464 [ procure pizza, beer, repeat ]
|
|
|
465 cd src
|
|
|
466 make CC="icc -W0,-mP1COPT_max_tree_size=3000" font-lock.o extents.o
|
|
|
467 make LD=icc
|
|
|
468
|
|
|
469 If you want sound support, get the tls566 supplement from
|
|
|
470 ftp.sco.com:/TLS or any of its mirrors. It works just groovy
|
|
|
471 with XEmacs.
|
|
|
472
|
|
|
473 The M-x manual-entry is known not to work. If you know Lisp and would
|
|
|
474 like help in making it work, e-mail me at <robertl@dgii.com>.
|
|
|
475 (UNCHECKED for 19.15 -- it might work).
|
|
|
476
|
|
|
477 In earlier releases, gnuserv/gnuclient/gnudoit would open a frame
|
|
|
478 just fine, but the client would lock up and the server would
|
|
|
479 terminate when you used C-x # to close the frame. This is now
|
|
|
480 fixed in XEmacs.
|
|
|
481
|
|
|
482 In etc/ there are two files of note. emacskeys.sco and emacsstrs.sco.
|
|
|
483 The comments at the top of emacskeys.sco describe its function, and
|
|
|
484 the emacstrs.sco is a suitable candidate for /usr/lib/keyboard/strings
|
|
|
485 to take advantage of the keyboard map in emacskeys.sco.
|
|
|
486
|
|
276
|
487 Note: Much of the above entry is probably not valid for XEmacs 21.0
|
|
207
|
488 and later.

490 ** Cygwin
|
|
|
491 *** In general use etc/check_cygwin_setup.sh to trap environment problems.
|
|
|
492
|
|
|
493 The script etc/check_cygwin_setup.sh will attempt to detect whether
|
|
|
494 you have a suitable environment for building. This script may not work
|
|
|
495 correctly if you are using ash instead of bash (see below).
|
|
|
496
|
|
|
497 *** X11 not detected.
|
|
|
498
|
|
|
499 This is usually because xmkmf is not in your path or because you are
|
|
|
500 using the default cygwin shell. The default cygwin shell (/bin/sh.exe)
|
|
|
501 is ash which appears to work in most circumstances but has some wierd
|
|
|
502 failure modes. I recommend replacing sh.exe with bash.exe, this will
|
|
|
503 mean configure is slower but more reliable.
|
|
|
504
|
|
|
505 *** Subprocesses do not work.
|
|
|
506
|
|
|
507 You do not have "tty" in your CYGWIN32 (for b19) or CYGWIN (for b20)
|
|
|
508 environment variable. This must be set in your autoexec.bat (win95) or
|
|
|
509 the system properties (winnt) as it must be read before the cygwin dll
|
|
|
510 initializes.
|
|
|
511
|
|
|
512 *** ^G does not work on hung subprocesses.
|
|
|
513
|
|
|
514 This is a known problem. It can be remedied with cygwin b20 or greater
|
|
|
515 by defining BROKEN_SIGIO in src/s/cygwin32.h, however this currently
|
|
|
516 leads to instability in XEmacs.
|
|
|
517
|
|
|
518 *** The XEmacs executable crashes at startup.
|
|
|
519
|
|
|
520 This can be caused by many things.
|
|
|
521
|
|
|
522 If you are running with X11 you need to have cygwin b19 or cygwin
|
|
|
523 b20.1 or greater, cygwin b20 will not work.
|
|
|
524
|
|
|
525 If you are running with cygwin b19 make sure you are using egcs 1.0.2
|
|
|
526 rather than vanilla gcc. XEmacs builds by default with -O3 which does
|
|
|
527 not work with the gcc that ships with b19. Alternatively use -O2.
|
|
|
528
|
|
|
529 *** The info files will not build.
|
|
|
530
|
|
|
531 makeinfo that ships with cygwin (all versions) is a noop. You need to
|
|
|
532 obtain makeinfo from somewhere or build it yourself.
|
|
|
533
|
|
|
534 *** I have no graphics.
|
|
|
535
|
|
|
536 You need to obtain the various graphics libraries. Pre-built versions
|
|
|
537 of these and the X libraries are located on the XEmacs website in
|
|
|
538 ftp://ftp.xemacs.org/pub/aux/cygwin*.
|
|
|
539
|
|
|
540 *** There are no images in the toolbar buttons.
|
|
|
541
|
|
|
542 You need version 4.71 of commctrl.dll which does not ship with windows
|
|
|
543 95. You can get this by installing IE 4.0 or downloading it from the
|
|
|
544 microsoft website.

547 * Problems with running XEmacs
|
|
|
548 ==============================
|
|
|
549 ** General
|
|
|
550 *** C-z just refreshes the screen instead of suspending Emacs.
|
|
124
|
551
|
|
|
552 You are probably using a shell that doesn't support job control, even
|
|
197
|
553 though the system itself is capable of it. Try using a different
|
|
|
554 shell.
|
|
124
|
555
|
|
312
|
556 *** You type Control-H (Backspace) expecting to delete characters.
|
|
124
|
557
|
|
|
558 Emacs has traditionally used Control-H for help; unfortunately this
|
|
355
|
559 interferes with its use as Backspace on TTY's. As of XEmacs 21,
|
|
|
560 XEmacs looks at the "erase" setting of TTY structures and maps C-h to
|
|
|
561 backspace when erase is set to C-h. This is sort of a special hack,
|
|
|
562 but it makes it possible for you to use the standard:
|
|
|
563
|
|
|
564 stty erase ^H
|
|
124
|
565
|
|
355
|
566 to get your backspace key to erase characters. The erase setting is
|
|
|
567 recorded in the Lisp variable `tty-erase-char', which you can use to
|
|
|
568 tune the settings in your .emacs.
|
|
124
|
569
|
|
355
|
570 A major drawback of this is that when C-h becomes backspace, it no
|
|
|
571 longer invokes help. In that case, you need to use f1 for help, or
|
|
|
572 bind another key. An example of the latter is the following code,
|
|
|
573 which moves help to Meta-? (ESC ?):
|
|
124
|
574
|
|
355
|
575 (global-set-key "\M-?" 'help-command)
|
|
124
|
576
|
|
312
|
577 *** Mail agents (VM, Gnus, rmail) cannot get new mail
|
|
197
|
578
|
|
|
579 rmail and VM get new mail from /usr/spool/mail/$USER using a program
|
|
|
580 called `movemail'. This program interlocks with /bin/mail using the
|
|
|
581 protocol defined by /bin/mail.
|
|
|
582
|
|
|
583 There are two different protocols in general use. One of them uses
|
|
|
584 the `flock' system call. The other involves creating a lock file;
|
|
|
585 `movemail' must be able to write in /usr/spool/mail in order to do
|
|
|
586 this. You control which one is used by defining, or not defining, the
|
|
|
587 macro MAIL_USE_FLOCK in config.h or the m- or s- file it includes. IF
|
|
|
588 YOU DON'T USE THE FORM OF INTERLOCKING THAT IS NORMAL ON YOUR SYSTEM,
|
|
|
589 YOU CAN LOSE MAIL!
|
|
|
590
|
|
|
591 If your system uses the lock file protocol, and fascist restrictions
|
|
|
592 prevent ordinary users from writing the lock files in /usr/spool/mail,
|
|
|
593 you may need to make `movemail' setgid to a suitable group such as
|
|
|
594 `mail'. To do this, use the following commands (as root) after doing
|
|
|
595 the make install.
|
|
|
596
|
|
|
597 chgrp mail movemail
|
|
|
598 chmod 2755 movemail
|
|
|
599
|
|
|
600 Installation normally copies movemail from the build directory to an
|
|
|
601 installation directory which is usually under /usr/local/lib. The
|
|
|
602 installed copy of movemail is usually in the directory
|
|
|
603 /usr/local/lib/emacs/VERSION/TARGET. You must change the group and
|
|
|
604 mode of the installed copy; changing the group and mode of the build
|
|
|
605 directory copy is ineffective.

607 *** VM appears to hang in large folders.
|
|
124
|
608
|
|
|
609 This is normal (trust us) when upgrading to VM-6.22 from earlier
|
|
|
610 versions. Let VM finish what it is doing and all will be well.

615 old .elc files will be loaded, and your changes will not be seen. To
|
|

626 of the "default" face; in this way, your bold and italic fonts will
|
|
|
627 have the appropriate size and family. However, emacs can only be
|
|
|
628 clever in this way if you have specified the default font using the
|
|
|
629 XLFD (X Logical Font Description) format, which looks like
|
|
0
|
630
|
|
|
631 *-courier-medium-r-*-*-*-120-*-*-*-*-*-*
|
|
|
632

637 and fixed
|
|
|
638 and 9x13
|
|
|
639
|
|
|
640 then emacs won't be able to guess the names of the "bold" and "italic"
|
|
|
641 versions. All X fonts can be referred to via XLFD-style names, so you
|
|
|
642 should use those forms. See the man pages for X(1), xlsfonts(1), and
|
|

643 xfontsel(1).

0
|
646
|
|
|
647 Two causes have been seen for such problems.
|
|
|
648
|
|
|
649 1) On a system where getpagesize is not a system call, it is defined
|
|
|
650 as a macro. If the definition (in both unexec.c and malloc.c) is wrong,
|
|
|
651 it can cause problems like this. You might be able to find the correct
|
|
|
652 value in the man page for a.out (5).
|
|
|
653
|
|
|
654 2) Some systems allocate variables declared static among the
|
|
|
655 initialized variables. Emacs makes all initialized variables in most
|
|
|
656 of its files pure after dumping, but the variables declared static and
|
|
|
657 not initialized are not supposed to be pure. On these systems you
|
|
|
658 may need to add "#define static" to the m- or the s- file.
|
|
|
659
|
|

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

0
|
661
|
|
|
662 Try evaluating the form (setq lock-directory nil) and see if that helps.
|
|
|
663 There is a problem with file-locking on some systems (possibly related
|
|
|
664 to NFS) that I don't understand. Please send mail to the address
|
|
|
665 xemacs@xemacs.org if you figure this one out.
|
|
|
666

312
|
667 *** When emacs starts up, I get lots of warnings about unknown keysyms.
|
|
124
|
668
|
|
|
669 If you are running the prebuilt binaries, the Motif library expects to find
|
|
|
670 certain thing in the XKeysymDB file. This file is normally in /usr/lib/X11/
|
|
|
671 or in /usr/openwin/lib/. If you keep yours in a different place, set the
|
|
|
672 environment variable $XKEYSYMDB to point to it before starting emacs. If
|
|
|
673 you still have the problem after doing that, perhaps your version of X is
|
|
|
674 too old. There is a copy of the MIT X11R5 XKeysymDB file in the emacs `etc'
|
|
|
675 directory. Try using that one.

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

|

197

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

689 most window managers don't implement them correctly.

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

692 handling. Sufficiently recent versions of tvtwm have been fixed. In
|
|
|
693 addition, if you're using twm, make sure you have not specified
|
|
|
694 "NoTitleFocus" in your .tvtwmrc file. The very nature of this option
|
|

695 makes twm do some illegal focus tricks, even with the patch.

709 *** Emacs spontaneously displays "I-search: " at the bottom of the screen.
|
|
0
|
710
|
|
|
711 This means that Control-S/Control-Q (XON/XOFF) "flow control" is being
|
|
|
712 used. C-s/C-q flow control is bad for Emacs editors because it takes
|
|
|
713 away C-s and C-q as user commands. Since editors do not output long
|
|
|
714 streams of text without user commands, there is no need for a
|
|
|
715 user-issuable "stop output" command in an editor; therefore, a
|
|
|
716 properly designed flow control mechanism would transmit all possible
|
|
|
717 input characters without interference. Designing such a mechanism is
|
|
|
718 easy, for a person with at least half a brain.
|
|
|
719
|
|
|
720 There are three possible reasons why flow control could be taking place:
|
|
|
721
|
|
|
722 1) Terminal has not been told to disable flow control
|
|
|
723 2) Insufficient padding for the terminal in use
|
|
|
724 3) Some sort of terminal concentrator or line switch is responsible
|
|
|
725
|
|
|
726 First of all, many terminals have a set-up mode which controls whether
|
|
|
727 they generate XON/XOFF flow control characters. This must be set to
|
|
|
728 "no XON/XOFF" in order for Emacs to work. Sometimes there is an
|
|
|
729 escape sequence that the computer can send to turn flow control off
|
|
|
730 and on. If so, perhaps the termcap `ti' string should turn flow
|
|
|
731 control off, and the `te' string should turn it on.
|
|
|
732
|
|
|
733 Once the terminal has been told "no flow control", you may find it
|
|
|
734 needs more padding. The amount of padding Emacs sends is controlled
|
|
|
735 by the termcap entry for the terminal in use, and by the output baud
|
|
|
736 rate as known by the kernel. The shell command `stty' will print
|
|
|
737 your output baud rate; `stty' with suitable arguments will set it if
|
|
|
738 it is wrong. Setting to a higher speed causes increased padding. If
|
|
|
739 the results are wrong for the correct speed, there is probably a
|
|
|
740 problem in the termcap entry. You must speak to a local Unix wizard
|
|
|
741 to fix this. Perhaps you are just using the wrong terminal type.
|
|
|
742
|
|
|
743 For terminals that lack a "no flow control" mode, sometimes just
|
|
|
744 giving lots of padding will prevent actual generation of flow control
|
|
|
745 codes. You might as well try it.
|
|
|
746
|
|
|
747 If you are really unlucky, your terminal is connected to the computer
|
|
|
748 through a concentrator which sends XON/XOFF flow control to the
|
|
|
749 computer, or it insists on sending flow control itself no matter how
|
|
|
750 much padding you give it. Unless you can figure out how to turn flow
|
|
|
751 control off on this concentrator (again, refer to your local wizard),
|
|
|
752 you are screwed! You should have the terminal or concentrator
|
|
|
753 replaced with a properly designed one. In the mean time, some drastic
|
|
|
754 measures can make Emacs semi-work.
|
|
|
755
|
|
|
756 You can make Emacs ignore C-s and C-q and let the operating system
|
|
|
757 handle them. To do this on a per-session basis, just type M-x
|
|
|
758 enable-flow-control RET. You will see a message that C-\ and C-^ are
|
|
|
759 now translated to C-s and C-q. (Use the same command M-x
|
|
|
760 enable-flow-control to turn *off* this special mode. It toggles flow
|
|
|
761 control handling.)
|
|
|
762
|
|
|
763 If C-\ and C-^ are inconvenient for you (for example, if one of them
|
|
|
764 is the escape character of your terminal concentrator), you can choose
|
|
|
765 other characters by setting the variables flow-control-c-s-replacement
|
|
|
766 and flow-control-c-q-replacement. But choose carefully, since all
|
|
|
767 other control characters are already used by emacs.
|
|
|
768
|
|
|
769 IMPORTANT: if you type C-s by accident while flow control is enabled,
|
|
|
770 Emacs output will freeze, and you will have to remember to type C-q in
|
|
|
771 order to continue.
|
|
|
772
|
|
|
773 If you work in an environment where a majority of terminals of a
|
|
|
774 certain type are flow control hobbled, you can use the function
|
|
|
775 `enable-flow-control-on' to turn on this flow control avoidance scheme
|
|
|
776 automatically. Here is an example:
|
|
|
777
|
|
|
778 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")
|
|
|
779
|
|
|
780 If this isn't quite correct (e.g. you have a mixture of flow-control hobbled
|
|
|
781 and good vt200 terminals), you can still run enable-flow-control
|
|
|
782 manually.
|
|
|
783
|
|
|
784 I have no intention of ever redesigning the Emacs command set for the
|
|
|
785 assumption that terminals use C-s/C-q flow control. XON/XOFF flow
|
|
|
786 control technique is a bad design, and terminals that need it are bad
|
|
|
787 merchandise and should not be purchased. Now that X is becoming
|
|
|
788 widespread, XON/XOFF seems to be on the way out. If you can get some
|
|
|
789 use out of GNU Emacs on inferior terminals, more power to you, but I
|
|
|
790 will not make Emacs worse for properly designed systems for the sake
|
|
|
791 of inferior systems.

793 *** Control-S and Control-Q commands are ignored completely.
|
|
0
|
794
|
|
|
795 For some reason, your system is using brain-damaged C-s/C-q flow
|
|
|
796 control despite Emacs's attempts to turn it off. Perhaps your
|
|
|
797 terminal is connected to the computer through a concentrator
|
|
|
798 that wants to use flow control.
|
|
|
799
|
|
|
800 You should first try to tell the concentrator not to use flow control.
|
|
|
801 If you succeed in this, try making the terminal work without
|
|
|
802 flow control, as described in the preceding section.
|
|
|
803
|
|
|
804 If that line of approach is not successful, map some other characters
|
|
|
805 into C-s and C-q using keyboard-translate-table. The example above
|
|
|
806 shows how to do this with C-^ and C-\.

811 Some versions of rlogin (and possibly telnet) do not pass flow
|
|
|
812 control characters to the remote system to which they connect.
|
|
|
813 On such systems, emacs on the remote system cannot disable flow
|
|
|
814 control on the local system.
|
|
|
815
|
|
|
816 One way to cure this is to disable flow control on the local host
|
|
|
817 (the one running rlogin, not the one running rlogind) using the
|
|
|
818 stty command, before starting the rlogin process. On many systems,
|
|
120
|
819 `stty start u stop u' will do this.
|
|
0
|
820
|
|
|
821 Some versions of tcsh will prevent even this from working. One way
|
|
|
822 around this is to start another shell before starting rlogin, and
|
|
|
823 issue the stty command to disable flow control from that shell.
|
|
|
824
|
|
|
825 If none of these methods work, the best solution is to type
|
|
120
|
826 `M-x enable-flow-control' at the beginning of your emacs session, or
|
|
0
|
827 if you expect the problem to continue, add a line such as the
|
|
|
828 following to your .emacs (on the host running rlogind):
|
|
|
829
|
|
|
830 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")

|
|
197
|
836
|
|
|
837 XEmacs has fairly new TTY redisplay support (beginning from 19.12),
|
|
|
838 which doesn't include some basic TTY optimizations -- like using
|
|
|
839 scrolling regions to move around blocks of text. This is why
|
|
|
840 redisplay on the traditional terminals, or over slow lines can be very
|
|
|
841 slow.

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

850 combination of features specified for that terminal.

0
|
851
|
|
|
852 The first step in tracking this down is to record what characters
|
|
|
853 Emacs is sending to the terminal. Execute the Lisp expression
|
|
120
|
854 (open-termscript "./emacs-script") to make Emacs write all terminal
|
|
|
855 output into the file ~/emacs-script as well; then do what makes the
|
|
|
856 screen update wrong, and look at the file and decode the characters
|
|
|
857 using the manual for the terminal. There are several possibilities:
|
|
0
|
858
|
|
|
859 1) The characters sent are correct, according to the terminal manual.
|
|
|
860
|
|
|
861 In this case, there is no obvious bug in Emacs, and most likely you
|
|
|
862 need more padding, or possibly the terminal manual is wrong.
|
|
|
863
|
|
120
|
864 2) The characters sent are incorrect, due to an obscure aspect of the
|
|
|
865 terminal behavior not described in an obvious way by termcap.
|
|
0
|
866
|
|
120
|
867 This case is hard. It will be necessary to think of a way for Emacs
|
|
|
868 to distinguish between terminals with this kind of behavior and other
|
|
|
869 terminals that behave subtly differently but are classified the same
|
|
|
870 by termcap; or else find an algorithm for Emacs to use that avoids the
|
|
|
871 difference. Such changes must be tested on many kinds of terminals.

934 *** Inability to send an Alt-modified key, when Emacs is communicating
|
|
|
935 directly with an X server.
|
|
|
936
|
|
|
937 If you have tried to bind an Alt-modified key as a command, and it
|
|
|
938 does not work to type the command, the first thing you should check is
|
|
|
939 whether the key is getting through to Emacs. To do this, type C-h c
|
|
|
940 followed by the Alt-modified key. C-h c should say what kind of event
|
|
|
941 it read. If it says it read an Alt-modified key, then make sure you
|
|
|
942 have made the key binding correctly.
|
|
|
943
|
|
|
944 If C-h c reports an event that doesn't have the Alt modifier, it may
|
|
|
945 be because your X server has no key for the Alt modifier. The X
|
|
|
946 server that comes from MIT does not set up the Alt modifier by
|
|
|
947 default.
|
|
|
948
|
|
|
949 If your keyboard has keys named Alt, you can enable them as follows:
|
|
|
950
|
|
|
951 xmodmap -e 'add mod2 = Alt_L'
|
|
|
952 xmodmap -e 'add mod2 = Alt_R'
|
|
|
953
|
|
|
954 If the keyboard has just one key named Alt, then only one of those
|
|
|
955 commands is needed. The modifier `mod2' is a reasonable choice if you
|
|
|
956 are using an unmodified MIT version of X. Otherwise, choose any
|
|
|
957 modifier bit not otherwise used.
|
|
|
958
|
|
|
959 If your keyboard does not have keys named Alt, you can use some other
|
|
|
960 keys. Use the keysym command in xmodmap to turn a function key (or
|
|
|
961 some other 'spare' key) into Alt_L or into Alt_R, and then use the
|
|
|
962 commands show above to make them modifier keys.
|
|
|
963
|
|
|
964 Note that if you have Alt keys but no Meta keys, Emacs translates Alt
|
|
|
965 into Meta. This is because of the great importance of Meta in Emacs.
|
|
|
966
|
|
|
967 *** In Shell mode, you get a ^M at the end of every line.
|
|
|
968
|
|
|
969 This happens to people who use tcsh, because it is trying to be too
|
|
|
970 smart. It sees that the Shell uses terminal type `unknown' and turns
|
|
|
971 on the flag to output ^M at the end of each line. You can fix the
|
|
|
972 problem by adding this to your .cshrc file:
|
|
|
973
|
|
|
974 if ($?EMACS) then
|
|
|
975 if ($EMACS == "t") then
|
|
|
976 unset edit
|
|
|
977 stty -icrnl -onlcr -echo susp ^Z

|
|

983

|
|
984 This comes from having an invalid X resource, such as
|
|
|
985 emacs*Cursor: black
|
|
|
986 (which is invalid because it specifies a color name for something
|
|
|
987 that isn't a color.)

989 The fix is to correct your X resources.

991 *** Once you pull down a menu from the menubar, it won't go away.
|
|
|
992
|
|
|
993 It has been claimed that this is caused by a bug in certain very old
|
|
|
994 (1990?) versions of the twm window manager. It doesn't happen with
|
|
|
995 recent vintages, or with other window managers.

|
997 *** Emacs ignores the "help" key when running OLWM.
|
|
|
998
|
|
|
999 OLWM grabs the help key, and retransmits it to the appropriate client
|
|
|
1000 using XSendEvent. Allowing emacs to react to synthetic events is a
|
|
|
1001 security hole, so this is turned off by default. You can enable it by
|
|
|
1002 setting the variable x-allow-sendevents to t. You can also cause fix
|
|
|
1003 this by telling OLWM to not grab the help key, with the null binding
|
|
|
1004 "OpenWindows.KeyboardCommand.Help:".

1006 *** Programs running under terminal emulator do not recognize `emacs'
|

1007 terminal type.
|
|
|
1008
|
|
|
1009 The cause of this is a shell startup file that sets the TERMCAP
|
|
|
1010 environment variable. The terminal emulator uses that variable to
|
|
|
1011 provide the information on the special terminal type that Emacs
|
|
|
1012 emulates.
|
|
|
1013
|
|
|
1014 Rewrite your shell startup file so that it does not change TERMCAP
|
|
|
1015 in such a case. You could use the following conditional which sets
|
|
|
1016 it only if it is undefined.
|
|
|
1017
|
|
|
1018 if ( ! ${?TERMCAP} ) setenv TERMCAP ~/my-termcap-file
|
|
|
1019
|
|
|
1020 Or you could set TERMCAP only when you set TERM--which should not
|
|
|
1021 happen in a non-login shell.

1089 you have probably compiled using an ANSI C compiler, but with non-ANSI

|
|
1090 include files. In particular, on Suns, the file
|
|
|
1091 /usr/include/sun/audioio.h uses the _IOW macro to define the constant
|
|
|
1092 AUDIOSETQSIZE. _IOW in turn uses a K&R preprocessor feature that is
|
|
|
1093 now explicitly forbidden in ANSI preprocessors, namely substitution
|
|
|
1094 inside character constants. All ANSI C compilers must provide a
|
|
|
1095 workaround for this problem. Lucid's C compiler is shipped with a new
|
|
|
1096 set of system include files. If you are using GCC, there is a script
|
|
|
1097 called fixincludes that creates new versions of some system include
|

1098 files that use this obsolete feature.

1132
|
|
|
1133 Be sure also to edit x/config/cf/sun.cf so that OSMinorVersion is 4
|
|
|
1134 (as it should be for Solaris 2.4). The file has three definitions for
|
|
|
1135 OSMinorVersion: the first is for x86, the second for SPARC under

1136 Solaris, and the third for SunOS 4. Make sure to update the

1137 definition for your type of machine and system.
|
|
|
1138
|
|
|
1139 Then do `make Everything' in the top directory of X11R6, to rebuild

|

0
|
1165
|
|
124
|
1166 Many emacs mail user agents (VM and rmail, for instance) use the
|
|
|
1167 sendmail.el library. This library can arrange for mail to be
|
|
|
1168 delivered by passing messages to the /usr/lib/sendmail (usually)
|
|
|
1169 program . In doing so, it passes the '-t' flag to sendmail, which
|
|
|
1170 means that the name of the recipient of the message is not on the
|
|
|
1171 command line and, therefore, that sendmail must parse the message to
|
|
|
1172 obtain the destination address.
|
|
|
1173
|
|
|
1174 There is a bug in the SunOS4.1.1 and SunOS4.1.3 versions of sendmail.
|
|
|
1175 In short, when given the -t flag, the SunOS sendmail won't recognize
|
|
|
1176 non-local (i.e. NIS) aliases. It has been reported that the Solaris
|
|
|
1177 2.x versions of sendmail do not have this bug. For those using SunOS
|
|
|
1178 4.1, the best fix is to install sendmail V8 or IDA sendmail (which
|
|
|
1179 have other advantages over the regular sendmail as well). At the time
|
|
|
1180 of this writing, these official versions are available:
|
|
|
1181
|
|
|
1182 Sendmail V8 on ftp.cs.berkeley.edu in /ucb/sendmail:

1195
|
|
124
|
1196 This typically happens on Suns and other systems that use shared
|
|
|
1197 libraries. The cause is that the site has installed a version of the
|
|
|
1198 shared library which uses a name server--but has not installed a
|
|
|
1199 similar version of the unshared library which Emacs uses.
|

|
1200
|
|
124
|
1201 The result is that most programs, using the shared library, work with
|
|
|
1202 the nameserver, but Emacs does not.
|
|
|
1203
|
|
|
1204 The fix is to install an unshared library that corresponds to what you
|
|

1205 installed in the shared library, and then relink Emacs.

|
1209 If you have already installed the name resolver in the file libresolv.a,
|
|
|
1210 then you need to compile Emacs to use that library. The easiest way to
|
|
|
1211 do this is to add to config.h a definition of LIBS_SYSTEM, LIBS_MACHINE
|
|
|
1212 or LIB_STANDARD which uses -lresolv. Watch out! If you redefine a macro
|
|
|
1213 that is already in use in your configuration to supply some other libraries,
|
|
|
1214 be careful not to lose the others.
|
|
|
1215
|
|
|
1216 Thus, you could start by adding this to config.h:
|
|
|
1217
|
|
|
1218 #define LIBS_SYSTEM -lresolv
|
|
|
1219
|
|
|
1220 Then if this gives you an error for redefining a macro, and you see that
|
|
|
1221 the s- file defines LIBS_SYSTEM as -lfoo -lbar, you could change config.h
|
|
|
1222 again to say this:
|
|
|
1223
|
|
|
1224 #define LIBS_SYSTEM -lresolv -lfoo -lbar

1229 On SunOS systems, this problem has been seen to be a result of an

1230 incomplete installation of gcc 2.2 which allowed some non-ANSI

1246 One user on a Linux system reported that this problem went away with
|
|
|
1247 installation of a new X server. The failing server was XFree86 3.1.1.

|
1248 XFree86 3.1.2 works.

1249
|
|
|
1250 *** Slow startup on Linux.
|
|
|
1251
|
|
|
1252 People using systems based on the Linux kernel sometimes report that
|
|
|
1253 startup takes 10 to 15 seconds longer than `usual'.
|
|
|
1254
|
|
|
1255 This is because Emacs looks up the host name when it starts.
|
|
|
1256 Normally, this takes negligible time; the extra delay is due to
|
|
|
1257 improper system configuration. This problem can occur for both
|
|
|
1258 networked and non-networked machines.
|
|
|
1259
|
|
|
1260 Here is how to fix the configuration. It requires being root.
|
|
|
1261
|
|
|
1262 **** Networked Case
|
|
|
1263
|
|
|
1264 First, make sure the files `/etc/hosts' and `/etc/host.conf' both
|
|
|
1265 exist. The first line in the `/etc/hosts' file should look like this
|
|
|
1266 (replace HOSTNAME with your host name):
|
|
|
1267
|
|
|
1268 127.0.0.1 localhost HOSTNAME
|
|
|
1269
|
|
|
1270 Also make sure that the `/etc/host.conf' files contains the following
|
|
|
1271 lines:
|
|
|
1272
|
|
|
1273 order hosts, bind
|
|
|
1274 multi on
|
|
|
1275
|
|
|
1276 Any changes, permanent and temporary, to the host name should be
|
|
|
1277 indicated in the `/etc/hosts' file, since it acts a limited local
|
|
|
1278 database of addresses and names (e.g., some SLIP connections
|
|
|
1279 dynamically allocate ip addresses).
|
|
|
1280
|
|
|
1281 **** Non-Networked Case
|
|
|
1282
|
|
|
1283 The solution described in the networked case applies here as well.
|
|
|
1284 However, if you never intend to network your machine, you can use a
|
|
|
1285 simpler solution: create an empty `/etc/host.conf' file. The command
|
|
|
1286 `touch /etc/host.conf' suffices to create the file. The `/etc/hosts'
|
|
|
1287 file is not necessary with this approach.
|
|
|
1288
|
|
|
1289
|
|
|
1290 ** IRIX
|
|
|
1291 *** On Irix, I don't see the toolbar icons and I'm getting lots of
|
|
|
1292 entries in the warnings buffer.
|
|
|
1293
|
|
|
1294 SGI ships a really old Xpm library in /usr/lib which does not work at
|
|
|
1295 all well with XEmacs. The solution is to install your own copy of the
|
|
|
1296 latest version of Xpm somewhere and then use the --site-includes and
|
|
|
1297 --site-libraries flags to tell configure where to find it.
|
|
|
1298
|
|
|
1299 *** Trouble using ptys on IRIX, or running out of ptys.
|
|
|
1300
|
|
|
1301 The program mkpts (which may be in `/usr/adm' or `/usr/sbin') needs to
|
|
|
1302 be set-UID to root, or non-root programs like Emacs will not be able
|
|
|
1303 to allocate ptys reliably.
|
|
|
1304
|
|
|
1305 *** Motif dialog boxes lose on Irix.

1322 ** Digital UNIX/OSF/VMS/Ultrix
|
|
|
1323 *** XEmacs crashes on Digital Unix within font-lock, or when dealing
|
|
|
1324 with large compilation buffers.
|
|
|
1325
|
|
|
1326 The default stack size under Digital Unix is rather small (2M as
|
|
|
1327 opposed to Solaris 8M), hosing the regexp code, which uses alloca()
|
|
|
1328 extensively, overflowing the stack when complex regexps are used.
|
|
|
1329 Workarounds:
|
|
0
|
1330
|
|
312
|
1331 1) Increase your stack size, using `ulimit -s 8192' or a (t)csh
|
|
|
1332 equivalent;
|
|
|
1333
|
|
|
1334 2) Recompile regex.c with REGEX_MALLOC defined.

|
1336 *** The `Alt' key doesn't behave as `Meta' when running DECwindows.
|
|
|
1337
|
|
|
1338 The default DEC keyboard mapping has the Alt keys set up to generate the
|
|
|
1339 keysym `Multi_key', which has a meaning to xemacs which is distinct from that
|
|
|
1340 of the `Meta_L' and `Meta-R' keysyms. A second problem is that certain keys
|
|
|
1341 have the Mod2 modifier attached to them for no adequately explored reason.
|
|
|
1342 The correct fix is to pass this file to xmodmap upon starting X:
|
|
|
1343
|
|
|
1344 clear mod2
|
|
|
1345 keysym Multi_key = Alt_L
|
|
|
1346 add mod1 = Alt_L
|
|
|
1347 add mod1 = Alt_R
|
|
|

|
|
|
1349 *** The Compose key on a DEC keyboard does not work as Meta key.

|

1353 xmodmap -e 'keycode 0xb1 = Meta_L'

|
1354
|
|
|
1355 *** `expand-file-name' fails to work on any but the machine you dumped
|
|
|
1356 Emacs on.
|
|
|
1357
|
|
|
1358 On Ultrix, if you use any of the functions which look up information
|
|
|
1359 in the passwd database before dumping Emacs (say, by using
|
|
|
1360 expand-file-name in site-init.el), then those functions will not work
|
|
|
1361 in the dumped Emacs on any host but the one Emacs was dumped on.
|
|
|
1362
|
|
|
1363 The solution? Don't use expand-file-name in site-init.el, or in
|
|
|
1364 anything it loads. Yuck - some solution.
|
|
|
1365
|
|
|
1366 I'm not sure why this happens; if you can find out exactly what is
|
|
|
1367 going on, and perhaps find a fix or a workaround, please let us know.
|
|
|
1368 Perhaps the YP functions cache some information, the cache is included
|
|
|
1369 in the dumped Emacs, and is then inaccurate on any other host.

1372 ** HP-UX
|
|
|
1373 *** I get complaints about the mapping of my HP keyboard at startup,
|
|
|
1374 but I haven't changed anything.
|
|
|
1375
|
|
|
1376 The default HP keymap is set up to have Mod1 assigned to two different keys:
|
|
|
1377 Meta_L and Mode_switch (even though there is not actually a Mode_switch key on
|
|
|
1378 the keyboard -- it uses an "imaginary" keycode.) There actually is a reason
|
|
|
1379 for this, but it's not a good one. The correct fix is to execute this command
|
|
|
1380 upon starting X:
|
|
|
1381
|
|
|
1382 xmodmap -e 'remove mod1 = Mode_switch'
|

|
|
|
1394 my 9.07 build of 19.14b17 and my (old) build of 19.13 both exhibit
|
|
|
1395 the same behaviour. I've tried various hpux patches to no avail. If
|
|
|
1396 this problem cannot be solved before the release date, binary kits

1397 for HP *must* be linked statically against libc, otherwise this

1399 for this kit, as I won't be available to do it, unless 19.14 gets

1400 delayed until mid-june ;-). I think this problem will be an FAQ soon

1428 On HP-UX, you can get that error when the Emacs executable is on an NFS

1429 file system. HP-UX responds this way if it tries to swap in a page and
|
|

1430 does not get a response from the server within a timeout whose default

1431 value is just ten seconds.

1438
|
|
|
1439 The problem is that in your .cshrc you have something that tries to
|
|
197
|
1440 execute `tty`. If you are not running the shell on a real tty then tty
|
|
|
1441 will print "not a tty". Csh expects one word in some places, but tty

|
|
1442 is giving it back 3.
|
|
124
|
1443
|
|
197
|
1444 The solution is to add a pair of quotes around `tty` to make it a
|
|
|
1445 single word:
|

0
|
1446
|
|
124

1447 if (`tty` == "/dev/console")

1483
|
|
124
|
1484 There are a few incompatible changes in XEmacs, and these are the
|
|
|
1485 symptoms. Some of the emacs-lisp code you are running needs to be
|
|
|
1486 updated to be compatible with XEmacs.
|
|
|
1487
|
|
|
1488 The code should not treat keymaps as arrays (use `define-key', etc.),
|
|
|
1489 should not use obsolete variables like `unread-command-char' (use
|
|
197
|
1490 `unread-command-events'). Many (most) of the new ways of doing things

|
1494 GNU Emacs and XEmacs. We have provided modified versions of several
|
|
|
1495 popular emacs packages (dired, etc) which are compatible with this
|
|
|
1496 version of emacs. Check to make sure you have not set your load-path
|
|
|
1497 so that your private copies of these packages are being found before
|
|
|
1498 the versions in the lisp directory.

|
|
|
1500 Make sure that your load-path and your $EMACSLOADPATH environment

1534 ** XEmacs/Mule doesn't support TTY's satisfactorily.
|
|
223
|
1535
|
|
|
1536 This is a major problem, which we plan to address in a future release
|
|
|
1537 of XEmacs. Basically, XEmacs should have primitives to be told
|
|
|
1538 whether the terminal can handle international output, and which
|
|
|
1539 locale. Also, it should be able to do approximations of characters to
|
|
|
1540 the nearest supported by the locale.

1542 ** Internationalized (Asian) Isearch doesn't work.
|
|
144

|
|

1544 Currently, Isearch doesn't directly support any of the input methods
|
|
|
1545 that are not XIM based (like egg, canna and quail) (and there are
|
|
223
|
1546 potential problems with XIM version too...). If you're using egg
|
|
|
1547 there is a workaround. Hitting <RET> right after C-s to invoke
|
|
|
1548 Isearch will put Isearch in string mode, where a complete string can
|
|
|
1549 be typed into the minibuffer and then processed by Isearch afterwards.
|
|
|
1550 Since egg is now supported in the minibuffer using string mode you can
|
|
|
1551 now use egg to input your Japanese, Korean or Chinese string, then hit
|
|
|
1552 return to send that to Isearch and then use standard Isearch commands
|
|
|
1553 from there.

1555 ** Using egg and mousing around while in 'fence' mode screws up my
|
|
|
1556 buffer.
|
|
144
|
1557
|
|
|
1558 Don't do this. The fence modes of egg and canna are currently very
|
|
|
1559 modal, and messing with where they expect point to be and what they
|
|
|
1560 think is the current buffer is just asking for trouble. If you're
|
|
|
1561 lucky they will realize that something is awry, and simply delete the
|
|
|
1562 fence, but worst case can trash other buffers too. We've tried to
|
|
|
1563 protect against this where we can, but there still are many ways to
|
|
|
1564 shoot yourself in the foot. So just finish what you are typing into
|
|
|
1565 the fence before reaching for the mouse.

1567 ** Not all languages in Quail are supported like Devanagari and Indian
|
|
|
1568 languages, Lao and Tibetan.
|
|
|
1569
|
|
|
1570 Quail requires more work and testing. Although it has been ported to
|
|
|
1571 XEmacs, it works really well for Japanese and for the European
|
|
|
1572 languages.
|
|
|
1573
|
|
|
1574 ** Right-to-left mode is not yet implemented, so languages like
|
|
|
1575 Arabic, Hebrew and Thai don't work.
|
|
|
1576
|
|
|
1577 Getting this right requires more work. It may be implemented in a
|
|
|
1578 future XEmacs version, but don't hold your breath. If you know
|
|
|
1579 someone who is ready to implement this, please let us know.
|
|
|
1580
|
|
|
1581 ** We need more developers and native language testers. It's extremely
|
|
|
1582 difficult (and not particularly productive) to address languages that
|
|
|
1583 nobody is using and testing.
|
|
|
1584
|
|
|
1585 ** The kWnn and cWnn support for Chinese and Korean needs developers
|
|
|
1586 and testers. It probably doesn't work.
|
|
|
1587
|
|
|
1588 ** There are no `native XEmacs' TUTORIALs for any Asian languages,
|
|
|
1589 including Japanese. FSF Emacs and XEmacs tutorials are quite similar,
|
|
|
1590 so it should be sufficient to skim through the differences and apply
|
|
|
1591 them to the Japanese version.
|
|
|
1592
|
|
|
1593 ** We only have localized menus translated for Japanese, and the
|
|
|
1594 Japanese menus are developing bitrot (the Mule menu appears in
|
|
|
1595 English).
|
|
|
1596
|
|
|
1597 ** XIM is untested for any language other than Japanese.
