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.

19
|
|

|
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

|
327
|
33 *** egcs-1.1
|
|
|
34
|
|
|
35 There have been reports of egcs-1.1 not compiling XEmacs correctly on
|
|
|
36 Alpha Linux. There have also been reports that egcs-1.0.3a is O.K.
|
|
|
37
|
|
312
|
38 *** Don't use -O2 with gcc 2.7.2 under Intel/XXX without also using
|
|
223
|
39 `-fno-strength-reduce'.
|
|
124
|
40
|
|
|
41 gcc will generate incorrect code otherwise. This bug is present in at
|
|
|
42 least 2.6.x and 2.7.[0-2]. This bug has been fixed in GCC 2.7.2.1 and
|
|
263
|
43 later. This bug is O/S independent, but is limited to x86 architectures.
|
|
|
44
|
|
|
45 This problem is known to be fixed in egcs (or pgcc) 1.0 or later.
|
|
229
|
46
|
|
312
|
47 *** Don't use -O2 with gcc 2.7.2 under Intel architectures without also
|
|
229
|
48 using `-fno-caller-saves'.

49
|

50 gcc will generate incorrect code otherwise. This bug is still
|
|
|
51 present in gcc 2.7.2.3. There have been no reports to indicate the
|
|
|
52 bug is present in egcs 1.0 (or pgcc 1.0) or later. This bug is O/S
|
|
|
53 independent, but limited to x86 architectures.
|
|
|
54
|
|
|
55 This problem is known to be fixed in egcs (or pgcc) 1.0 or later.
|
|
124
|
56
|
|
312
|
57 *** When using gcc, you get the error message "undefined symbol __fixunsdfsi".
|
|
|
58 When using gcc, you get the error message "undefined symbol __main".
|
|
|
59
|
|
|
60 This means that you need to link with the gcc library. It may be called
|
|
|
61 "gcc-gnulib" or "libgcc.a"; figure out where it is, and define LIB_GCC in
|
|
|
62 config.h to point to it.
|
|
|
63
|
|
|
64 It may also work to use the GCC version of `ld' instead of the standard one.
|
|
|
65
|
|
|
66 *** Excessive optimization with pgcc can break XEmacs
|
|
124
|
67
|
|
|
68 It has been reported on some systems that compiling with -O6 can lead
|
|
|
69 to XEmacs failures. The workaround is to use a lower optimization
|
|
|
70 level. -O2 and -O4 have been tested extensively.
|
|
|
71
|
|
229
|
72 All of this depends heavily on the version of pgcc and the version
|
|
|
73 of libc. Snapshots near the release of pgcc-1.0 have been tested
|
|
|
74 extensively and no sign of breakage has been seen on systems using
|
|
|
75 glibc-2.
|
|
|
76
|
|
312
|
77 *** src/Makefile and lib-src/Makefile are truncated--most of the file missing.
|
|
229
|
78
|
|
312
|
79 This can happen if configure uses GNU sed version 2.03. That version
|
|
|
80 had a bug. GNU sed version 2.05 works properly.
|
|
124
|
81
|
|
312
|
82 *** When compiling with X11, you get "undefined symbol _XtStrings".
|
|
124
|
83
|
|
312
|
84 This means that you are trying to link emacs against the X11r4 version of
|
|
|
85 libXt.a, but you have compiled either Emacs or the code in the lwlib
|
|
|
86 subdirectory with the X11r5 header files. That doesn't work.
|
|
124
|
87
|
|
312
|
88 Remember, you can't compile lwlib for r4 and emacs for r5, or vice versa.
|
|
|
89 They must be in sync.
|
|
124
|
90
|
|
312
|
91 *** test-distrib says that the distribution has been clobbered
|
|
197
|
92 or, temacs prints "Command key out of range 0-127"
|
|
|
93 or, temacs runs and dumps xemacs, but xemacs totally fails to work.
|
|
|
94 or, temacs gets errors dumping xemacs
|
|
|
95
|
|
|
96 This can be because the .elc files have been garbled. Do not be
|
|
|
97 fooled by the fact that most of a .elc file is text: these are binary
|
|
|
98 files and can contain all 256 byte values.
|
|
|
99
|
|
|
100 In particular `shar' cannot be used for transmitting GNU Emacs. It
|
|
|
101 typically truncates "lines". (this does not apply to GNU shar, which
|
|
|
102 uses uuencode to encode binary files.)
|
|
|
103
|
|
|
104 If you have a copy of Emacs that has been damaged in its nonprinting
|
|
|
105 characters, you can fix them by running:
|
|
|
106
|
|
|
107 make all-elc
|
|
|
108
|
|
|
109 This will rebuild all the needed .elc files.
|
|
|
110
|
|
312
|
111 *** `compress' and `uncompress' not found and XFree86
|
|
|
112
|
|
|
113 XFree86 installs a very old version of libz.a by default ahead of where
|
|
|
114 more modern version of libz might be installed. This will cause problems
|
|
|
115 when attempting to link against libMagick. The fix is to remove the old
|
|
|
116 libz.a in the X11 binary directory.
|
|
|
117
|
|
|
118
|
|
|
119 ** AIX
|
|
316
|
120 *** On AIX 4.3, you must specify --with-dialogs=athena with configure
|
|
|
121
|
|
333
|
122 *** The libXt shipped with AIX 4.3 is broken. This causes xemacs -nw
|
|
|
123 to fail in various ways. The solution is to build against stock
|
|
|
124 X11R6.
|
|
|
125
|
|
312
|
126 *** On AIX, you get this compiler error message:
|
|
|
127
|
|
|
128 Processing include file ./XMenuInt.h
|
|
|
129 1501-106: (S) Include file X11/Xlib.h not found.
|
|
|
130
|
|
|
131 This means your system was installed with only the X11 runtime i.d
|
|
|
132 libraries. You have to find your sipo (bootable tape) and install
|
|
|
133 X11Dev... with smit.
|
|
|
134
|
|
|
135 *** On AIX 4.1.2, linker error messages such as
|
|
|
136 ld: 0711-212 SEVERE ERROR: Symbol .__quous, found in the global symbol table
|
|
|
137 of archive /usr/lib/libIM.a, was not defined in archive member shr.o.
|
|
|
138
|
|
|
139 This is a problem in libIM.a. You can work around it by executing
|
|
|
140 these shell commands in the src subdirectory of the directory where
|
|
|
141 you build Emacs:
|
|
|
142
|
|
|
143 cp /usr/lib/libIM.a .
|
|
|
144 chmod 664 libIM.a
|
|
|
145 ranlib libIM.a
|
|
|
146
|
|
|
147 Then change -lIM to ./libIM.a in the command to link temacs (in
|
|
|
148 Makefile).
|
|
|
149
|
|
|

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

155 further.

158 ** SunOS/Solaris
|
|
|
159 *** Link failure when using acc on a Sun.
|
|
|
160
|
|
|
161 To use acc, you need additional options just before the libraries, such as
|
|
|
162
|
|
|
163 /usr/lang/SC2.0.1/values-Xt.o -L/usr/lang/SC2.0.1/cg87 -L/usr/lang/SC2.0.1
|
|
|
164
|
|
|
165 and you need to add -lansi just before -lc.
|
|
|
166
|
|
|
167 The precise file names depend on the compiler version, so we
|
|
|
168 cannot easily arrange to supply them.
|
|
|
169
|
|
|
170 *** Problems finding X11 libraries on Solaris with Openwindows
|
|
|
171
|
|
|
172 Some users have reported problems in this area. The reported solution
|
|
|
173 is to define the environment variable OPENWINHOME, even if you must set
|
|
|
174 it to `/usr/openwin'.
|
|
|
175
|
|
|
176 *** Sed problems on Solaris 2.5
|
|
|
177
|
|
|
178 There have been reports of Sun sed truncating very lines in the
|
|
|
179 Makefile during configuration. The workaround is to use GNU sed or,
|
|
|
180 even better, think of a better way to generate Makefile, and send us a
|
|
|
181 patch. :-)
|
|
|
182
|
|
|
183 *** On Solaris 2 I get undefined symbols from libcurses.a.
|
|
|
184
|
|
|
185 You probably have /usr/ucblib/ on your LD_LIBRARY_PATH. Do the link with
|
|
|
186 LD_LIBRARY_PATH unset. Generally, avoid using any ucb* stuff when
|
|
|
187 building XEmacs.
|
|
|
188
|
|
|
189 *** On Solaris 2 I cannot make alloc.o, glyphs.o or process.o.
|
|
|
190
|
|
|
191 The SparcWorks C compiler may have difficulty building those modules
|
|
|
192 with optimization level -xO4. Try using only "-fast" optimization
|
|
|
193 for just those modules. (Or use gcc).
|
|
|
194
|
|
|
195 *** Solaris 2.3 /bin/sh coredumps during configuration.
|
|
|
196
|
|
|
197 This only occurs if you have LANG != C. This is a known bug with
|
|
|
198 /bin/sh fixed by installing Patch-ID# 101613-01. Or, you can use
|
|
|
199 bash, as a workaround.
|
|
|
200
|
|
|
201 *** On SunOS, you get linker errors
|
|
|
202 ld: Undefined symbol
|
|
|
203 _get_wmShellWidgetClass
|
|
|
204 _get_applicationShellWidgetClass
|
|
|
205
|
|
|
206 The fix to this is to install patch 100573 for OpenWindows 3.0
|
|
|
207 or link libXmu statically.
|
|
|
208
|
|
|
209 *** On Sunos 4, you get the error ld: Undefined symbol __lib_version.
|
|
|
210
|
|
|
211 This is the result of using cc or gcc with the shared library meant
|
|
|
212 for acc (the Sunpro compiler). Check your LD_LIBRARY_PATH and delete
|
|
|
213 /usr/lang/SC2.0.1 or some similar directory.
|
|
|
214
|
|
|
215 *** Undefined symbols when linking on Sunos 4.1.
|
|
|
216
|
|
|
217 If you get the undefined symbols _atowc _wcslen, _iswprint, _iswspace,
|
|
|
218 _iswcntrl, _wcscpy, and _wcsncpy, then you need to add -lXwchar after
|
|
|
219 -lXaw in the command that links temacs.
|
|
|
220
|
|
|
221 This problem seems to arise only when the international language
|
|
|
222 extensions to X11R5 are installed.
|
|
|
223
|
|
|
224 *** On a Sun running SunOS 4.1.1, you get this error message from GNU ld:
|
|
|
225
|
|
|
226 /lib/libc.a(_Q_sub.o): Undefined symbol __Q_get_rp_rd referenced from text segment
|
|
|
227
|
|
|
228 The problem is in the Sun shared C library, not in GNU ld.
|
|
|
229
|
|
|
230 The solution is to install Patch-ID# 100267-03 from Sun.
|
|
|
231
|
|
|
232 *** SunOS 4.1.2: undefined symbol _get_wmShellWidgetClass
|
|
|
233
|
|
|
234 Apparently the version of libXmu.so.a that Sun ships is hosed: it's missing
|
|
|
235 some stuff that is in libXmu.a (the static version). Sun has a patch for
|
|
|
236 this, but a workaround is to use the static version of libXmu, by changing
|
|
|
237 the link command from "-lXmu" to "-Bstatic -lXmu -Bdynamic". If you have
|
|
|
238 OpenWindows 3.0, ask Sun for these patches:
|
|
|
239 100512-02 4.1.x OpenWindows 3.0 libXt Jumbo patch
|
|
|
240 100573-03 4.1.x OpenWindows 3.0 undefined symbols with shared libXmu
|
|
|
241
|
|
|
242 *** Random other SunOS 4.1.[12] link errors.
|
|
|
243
|
|
|
244 The X headers and libraries that Sun ships in /usr/{include,lib}/X11 are
|
|
|
245 broken. Use the ones in /usr/openwin/{include,lib} instead.
|
|
|
246
|
|
|
247 ** Linux
|
|
|
248 *** Under Linux, you get "too many arguments to function `getpgrp'".
|
|
|
249
|
|
|
250 You have probably installed LessTiff under `/usr/local' and `libXm.so'
|
|
|
251 could not be found when linking `getpgrp()' test program, making XEmacs
|
|
|
252 think that `getpgrp()' takes an argument. Try adding `/usr/local/lib'
|
|
|
253 in `/etc/ld.so.conf' and run `ldconfig'. Then run XEmacs's `configure'
|
|
|
254 again. As with all problems of this type, reading the config.log file
|
|
|
255 generated from configure and seeing the log of how the test failed can
|
|
|
256 prove enlightening.
|
|
|
257
|
|
|
258 *** `Error: No ExtNode to pop!' on Linux systems with Lesstif.
|
|
197
|

261 appear to cause any harm.

265 This is a Linux problem where you've compiled the XEmacs binary on a libc
|
|
|
266 5.4 with version higher than 5.4.19 and attempted to run the binary against
|
|
|
267 an earlier version. The solution is to upgrade your old library.

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

272 Darrell Kindred <dkindred@cmu.edu> writes:
|
|
|
273 There are a couple of problems [with use of -rpath with Irix ld], though:
|
|
|
274
|
|
|
275 1. The ld in IRIX 5.3 ignores all but the last -rpath
|
|
|
276 spec, so the patched configure spits out a warning
|
|
|
277 if --x-libraries or --site-runtime-libraries are
|
|
|
278 specified under irix 5.x, and it only adds -rpath
|
|
|
279 entries for the --site-runtime-libraries. This bug was
|
|
|
280 fixed sometime between 5.3 and 6.2.
|
|
|
281
|
|
|
282 2. IRIX gcc 2.7.2 doesn't accept -rpath directly, so
|
|
|
283 it would have to be prefixed by -Xlinker or "-Wl,".
|
|
|
284 This would be fine, except that configure compiles with
|
|
|
285 ${CC-cc} $CFLAGS $LDFLAGS ...
|
|
|
286 rather than quoting $LDFLAGS with prefix-args, like
|
|
|
287 src/Makefile does. So if you specify --x-libraries
|
|
|
288 or --site-runtime-libraries, you must use --use-gcc=no,
|
|
|
289 or configure will fail.

|
|
|
299 in src/Makefile. Edit src/Makefile, after configure is run,
|
|

300 find that string, and take out the spaces.

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

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

310 syms.h.

316 that XEmacs coredumped when the cut or copy toolbar buttons were
|
|
|
317 pressed. This has been fixed by loading the SGI patchset (Feb 98)
|
|
|
318 without having to recompile XEmacs.
|
|
124
|
319
|
|
312
|
320 My versions are XEmacs 20.3 (problem first noted in 19.15) and IRIX
|
|
|
321 6.2, compiled using -n32. I'd guess that the relevant individual
|
|
|
322 patch was "SG0002580: multiple fixes for X libraries". SGI recommends
|
|
|
323 that the complete patch set be installed rather than parts of it.

325 ** Digital UNIX/OSF/VMS
|
|
|
326 *** On Digital UNIX, the DEC C compiler might have a problem compiling
|
|
197
|
327 some files.
|
|
124
|
328
|
|
|
329 In particular, src/extents.c and src/faces.c might cause the DEC C
|
|
|
330 compiler to abort. When this happens: cd src, compile the files by
|
|
|
331 hand, cd .., and redo the "make" command. When recompiling the files by
|
|
|
332 hand, use the old C compiler for the following versions of Digital UNIX:
|
|
|
333 - V3.n: Remove "-migrate" from the compile command.
|
|
|
334 - V4.n: Add "-oldc" to the compile command.
|
|
|
335
|
|
197
|
336 A related compiler bug has been fixed by the DEC compiler team. The
|
|
|
337 new versions of the compiler should run fine.

338
|
|
312
|
339 *** Under some versions of OSF XEmacs runs fine if built without
|
|
|
340 optimization but will crash randomly if built with optimization.
|
|
|
341
|
|
|
342 Using 'cc -g' is not sufficient to eliminate all optimization. Try
|
|
|
343 'cc -g -O0' instead.
|
|
|
344
|
|
|
345 *** Compilation errors on VMS.
|
|
|
346
|
|
|
347 Sorry, XEmacs does not work under VMS. You might consider working on
|
|
|
348 the port if you really want to have XEmacs work under VMS.

374 Some releases of XEmacs (e.g. 20.4) require GNU make to build

|
388 Unfortunately, XEmacs releases <21.0 don't work with Motif2.1. It
|
|
304
|
389 will compile but you will get excessive X11 errors like
|
|
|

|
|
|
391 xemacs: X Error of failed request: BadGC (invalid GC parameter)
|
|
|
392
|
|
|
393 and finally XEmacs gets killed. A workaround is to use the
|
|
|
394 Motif1.2_R6 libraries. You can the following line to your call to
|
|
|
395 configure:
|
|
|
396
|
|
|
397 --x-libraries="/usr/lib/Motif1.2_R6 -L/usr/lib/X11R6"
|
|
|
398
|
|
|
399 Make sure /usr/lib/Motif1.2_R6/libXm.sl is a link to
|
|
|
400 /usr/lib/Motif1.2_R6/libXm.3.

402 ** SCO OpenServer
|
|
|
403 *** Native cc on SCO OpenServer 5 is now OK. Icc may still throw you
|
|
197
|
404 a curve. Here is what Robert Lipe <robertl@arnet.com> says:
|
|
124
|
405
|
|
|
406 Unlike XEmacs 19.13, building with the native cc on SCO OpenServer 5
|
|
|
407 now produces a functional binary. I will typically build this
|
|
|
408 configuration for COFF with:
|
|
|
409
|
|
197
|
410 /path_to_xemacs_source/configure --with-gcc=no \
|
|
124
|
411 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
412 --with-xpm --with-xface --with-sound=nas
|
|
|
413
|
|
|
414 This version now supports ELF builds. I highly recommend this to
|
|
|
415 reduce the in-core footprint of XEmacs. This is now how I compile
|
|
|
416 all my test releases. Build it like this:
|
|
|
417
|
|
|
418 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
|
419 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
420 --with-xpm --with-xface --with-sound=nas --dynamic
|
|
|
421
|
|
|
422 The compiler known as icc [ supplied with the OpenServer 5 Development
|
|
|
423 System ] generates a working binary, but it takes forever to generate
|
|
|
424 XEmacs. ICC also whines more about the code than /bin/cc does. I do
|
|
|
425 believe all its whining is legitimate, however. Note that you do
|
|
|
426 have to 'cd src ; make LD=icc' to avoid linker errors.
|
|
|
427
|
|
|
428 The way I handle the build procedure is:
|
|
|
429
|
|
|
430 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
|
431 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
432 --with-xpm --with-xface --with-sound=nas --dynamic --compiler="icc"
|
|
|
433
|
|
|
434 NOTE I have the xpm, xface, and audio libraries and includes in
|
|
|
435 /usr/local/lib, /usr/local/include. If you don't have these,
|
|
|
436 don't include the "--with-*" arguments in any of my examples.
|
|
|
437
|
|
|
438 In previous versions of XEmacs, you had to override the defaults while
|
|
|
439 compiling font-lock.o and extents.o when building with icc. This seems
|
|
|
440 to no longer be true, but I'm including this old information in case it
|
|
|
441 resurfaces. The process I used was:
|
|
|
442
|
|
|
443 make -k
|
|
|
444 [ procure pizza, beer, repeat ]
|
|
|
445 cd src
|
|
|
446 make CC="icc -W0,-mP1COPT_max_tree_size=3000" font-lock.o extents.o
|
|
|
447 make LD=icc
|
|
|
448
|
|
|
449 If you want sound support, get the tls566 supplement from
|
|
|
450 ftp.sco.com:/TLS or any of its mirrors. It works just groovy
|
|
|
451 with XEmacs.
|
|
|
452
|
|
|
453 The M-x manual-entry is known not to work. If you know Lisp and would
|
|
|
454 like help in making it work, e-mail me at <robertl@dgii.com>.
|
|
|
455 (UNCHECKED for 19.15 -- it might work).
|
|
|
456
|
|
|
457 In earlier releases, gnuserv/gnuclient/gnudoit would open a frame
|
|
|
458 just fine, but the client would lock up and the server would
|
|
|
459 terminate when you used C-x # to close the frame. This is now
|
|
|
460 fixed in XEmacs.
|
|
|
461
|
|
|
462 In etc/ there are two files of note. emacskeys.sco and emacsstrs.sco.
|
|
|
463 The comments at the top of emacskeys.sco describe its function, and
|
|
|
464 the emacstrs.sco is a suitable candidate for /usr/lib/keyboard/strings
|
|
|
465 to take advantage of the keyboard map in emacskeys.sco.
|
|
|
466
|
|
276
|
467 Note: Much of the above entry is probably not valid for XEmacs 21.0
|
|
207
|
468 and later.

470 ** Cygwin
|
|
|
471 *** In general use etc/check_cygwin_setup.sh to trap environment problems.
|
|
|
472
|
|
|
473 The script etc/check_cygwin_setup.sh will attempt to detect whether
|
|
|
474 you have a suitable environment for building. This script may not work
|
|
|
475 correctly if you are using ash instead of bash (see below).
|
|
|
476
|
|
|
477 *** X11 not detected.
|
|
|
478
|
|
|
479 This is usually because xmkmf is not in your path or because you are
|
|
|
480 using the default cygwin shell. The default cygwin shell (/bin/sh.exe)
|
|
|
481 is ash which appears to work in most circumstances but has some wierd
|
|
|
482 failure modes. I recommend replacing sh.exe with bash.exe, this will
|
|
|
483 mean configure is slower but more reliable.
|
|
|
484
|
|
|
485 *** Subprocesses do not work.
|
|
|
486
|
|
|
487 You do not have "tty" in your CYGWIN32 (for b19) or CYGWIN (for b20)
|
|
|
488 environment variable. This must be set in your autoexec.bat (win95) or
|
|
|
489 the system properties (winnt) as it must be read before the cygwin dll
|
|
|
490 initializes.
|
|
|
491
|
|
|
492 *** ^G does not work on hung subprocesses.
|
|
|
493
|
|
|
494 This is a known problem. It can be remedied with cygwin b20 or greater
|
|
|
495 by defining BROKEN_SIGIO in src/s/cygwin32.h, however this currently
|
|
|
496 leads to instability in XEmacs.
|
|
|
497
|
|
|
498 *** The XEmacs executable crashes at startup.
|
|
|
499
|
|
|
500 This can be caused by many things.
|
|
|
501
|
|
|
502 If you are running with X11 you need to have cygwin b19 or cygwin
|
|
|
503 b20.1 or greater, cygwin b20 will not work.
|
|
|
504
|
|
|
505 If you are running with cygwin b19 make sure you are using egcs 1.0.2
|
|
|
506 rather than vanilla gcc. XEmacs builds by default with -O3 which does
|
|
|
507 not work with the gcc that ships with b19. Alternatively use -O2.
|
|
|
508
|
|
|
509 *** The info files will not build.
|
|
|
510
|
|
|
511 makeinfo that ships with cygwin (all versions) is a noop. You need to
|
|
|
512 obtain makeinfo from somewhere or build it yourself.
|
|
|
513
|
|
|
514 *** I have no graphics.
|
|
|
515
|
|
|
516 You need to obtain the various graphics libraries. Pre-built versions
|
|
|
517 of these and the X libraries are located on the XEmacs website in
|
|
|
518 ftp://ftp.xemacs.org/pub/aux/cygwin*.
|
|
|
519
|
|
|
520 *** There are no images in the toolbar buttons.
|
|
|
521
|
|
|
522 You need version 4.71 of commctrl.dll which does not ship with windows
|
|
|
523 95. You can get this by installing IE 4.0 or downloading it from the
|
|
|
524 microsoft website.

527 * Problems with running XEmacs
|
|
|
528 ==============================
|
|
|
529 ** General
|
|
|
530 *** C-z just refreshes the screen instead of suspending Emacs.
|
|
124
|
531
|
|
|
532 You are probably using a shell that doesn't support job control, even
|
|
197
|
533 though the system itself is capable of it. Try using a different
|
|
|
534 shell.
|
|
124
|
535
|
|
312
|
536 *** You type Control-H (Backspace) expecting to delete characters.
|
|
124
|
537
|
|
|
538 Emacs has traditionally used Control-H for help; unfortunately this
|
|
|
539 interferes with its use as Backspace on TTY's. One way to solve this
|
|
|
540 problem is to put this in your .emacs:
|
|
|
541
|
|
197
|
542 (when (eq tty-erase-char ?\C-h)
|
|
|
543 (keyboard-translate ?\C-h ?\C-?)
|
|
|
544 (global-set-key "\M-?" 'help-command))
|
|
124
|
545
|
|
197
|
546 This checks whether the TTY erase char is C-h, and if it is, makes
|
|
|
547 Control-H (Backspace) work sensibly, and moves help to Meta-? (ESC ?).
|
|
124
|
548
|
|
|
549 Note that you can probably also access help using F1.
|
|
|
550
|
|
312
|
551 *** Mail agents (VM, Gnus, rmail) cannot get new mail
|
|
197
|
552
|
|
|
553 rmail and VM get new mail from /usr/spool/mail/$USER using a program
|
|
|
554 called `movemail'. This program interlocks with /bin/mail using the
|
|
|
555 protocol defined by /bin/mail.
|
|
|
556
|
|
|
557 There are two different protocols in general use. One of them uses
|
|
|
558 the `flock' system call. The other involves creating a lock file;
|
|
|
559 `movemail' must be able to write in /usr/spool/mail in order to do
|
|
|
560 this. You control which one is used by defining, or not defining, the
|
|
|
561 macro MAIL_USE_FLOCK in config.h or the m- or s- file it includes. IF
|
|
|
562 YOU DON'T USE THE FORM OF INTERLOCKING THAT IS NORMAL ON YOUR SYSTEM,
|
|
|
563 YOU CAN LOSE MAIL!
|
|
|
564
|
|
|
565 If your system uses the lock file protocol, and fascist restrictions
|
|
|
566 prevent ordinary users from writing the lock files in /usr/spool/mail,
|
|
|
567 you may need to make `movemail' setgid to a suitable group such as
|
|
|
568 `mail'. To do this, use the following commands (as root) after doing
|
|
|
569 the make install.
|
|
|
570
|
|
|
571 chgrp mail movemail
|
|
|
572 chmod 2755 movemail
|
|
|
573
|
|
|
574 Installation normally copies movemail from the build directory to an
|
|
|
575 installation directory which is usually under /usr/local/lib. The
|
|
|
576 installed copy of movemail is usually in the directory
|
|
|
577 /usr/local/lib/emacs/VERSION/TARGET. You must change the group and
|
|
|
578 mode of the installed copy; changing the group and mode of the build
|
|
|
579 directory copy is ineffective.
|
|
|

|
|
312
|
581 *** VM appears to hang in large folders.
|
|
124
|
582
|
|
|
583 This is normal (trust us) when upgrading to VM-6.22 from earlier
|
|
|
584 versions. Let VM finish what it is doing and all will be well.
|

586 *** Changes made to .el files do not take effect.

0
|
587
|
|
197
|
588 You may have forgotten to recompile them into .elc files. Then the
|
|
|
589 old .elc files will be loaded, and your changes will not be seen. To
|
|
|
590 fix this, do `M-x byte-recompile-directory' and specify the directory
|
|
|
591 that contains the Lisp files.
|

|
592

594 older than the corresponding .el file.

598
|

197
|
599 The fonts of the "bold" and "italic" faces are generated from the font
|
|
|
600 of the "default" face; in this way, your bold and italic fonts will
|
|
|
601 have the appropriate size and family. However, emacs can only be
|
|
|
602 clever in this way if you have specified the default font using the
|
|
|
603 XLFD (X Logical Font Description) format, which looks like
|
|
0
|
604
|
|
|
605 *-courier-medium-r-*-*-*-120-*-*-*-*-*-*

606

613

614 then emacs won't be able to guess the names of the "bold" and "italic"
|
|
|
615 versions. All X fonts can be referred to via XLFD-style names, so you
|
|
|
616 should use those forms. See the man pages for X(1), xlsfonts(1), and
|
|
|
617 xfontsel(1).

|
624 as a macro. If the definition (in both unexec.c and malloc.c) is wrong,
|
|
|
625 it can cause problems like this. You might be able to find the correct
|
|

645 or in /usr/openwin/lib/. If you keep yours in a different place, set the

646 environment variable $XKEYSYMDB to point to it before starting emacs. If
|
|

647 you still have the problem after doing that, perhaps your version of X is

684
|
|
|
685 This means that Control-S/Control-Q (XON/XOFF) "flow control" is being
|
|
|
686 used. C-s/C-q flow control is bad for Emacs editors because it takes
|
|
|
687 away C-s and C-q as user commands. Since editors do not output long
|
|
|
688 streams of text without user commands, there is no need for a
|
|
|
689 user-issuable "stop output" command in an editor; therefore, a
|
|
|
690 properly designed flow control mechanism would transmit all possible
|
|
|
691 input characters without interference. Designing such a mechanism is
|
|
|
692 easy, for a person with at least half a brain.
|
|
|
693
|
|
|
694 There are three possible reasons why flow control could be taking place:
|
|
|
695
|
|
|
696 1) Terminal has not been told to disable flow control
|
|
|
697 2) Insufficient padding for the terminal in use
|
|
|
698 3) Some sort of terminal concentrator or line switch is responsible
|
|
|
699
|
|
|
700 First of all, many terminals have a set-up mode which controls whether
|
|
|
701 they generate XON/XOFF flow control characters. This must be set to
|
|
|
702 "no XON/XOFF" in order for Emacs to work. Sometimes there is an
|
|
|
703 escape sequence that the computer can send to turn flow control off
|
|
|
704 and on. If so, perhaps the termcap `ti' string should turn flow
|
|
|
705 control off, and the `te' string should turn it on.
|
|
|
706
|
|
|
707 Once the terminal has been told "no flow control", you may find it
|
|
|
708 needs more padding. The amount of padding Emacs sends is controlled
|
|
|
709 by the termcap entry for the terminal in use, and by the output baud
|
|
|
710 rate as known by the kernel. The shell command `stty' will print
|
|
|
711 your output baud rate; `stty' with suitable arguments will set it if
|
|
|
712 it is wrong. Setting to a higher speed causes increased padding. If
|
|
|
713 the results are wrong for the correct speed, there is probably a
|
|
|
714 problem in the termcap entry. You must speak to a local Unix wizard
|
|
|
715 to fix this. Perhaps you are just using the wrong terminal type.
|
|
|
716
|
|
|
717 For terminals that lack a "no flow control" mode, sometimes just
|
|
|
718 giving lots of padding will prevent actual generation of flow control
|
|
|
719 codes. You might as well try it.
|
|
|
720
|
|
|
721 If you are really unlucky, your terminal is connected to the computer
|
|
|
722 through a concentrator which sends XON/XOFF flow control to the
|
|
|
723 computer, or it insists on sending flow control itself no matter how
|
|
|
724 much padding you give it. Unless you can figure out how to turn flow
|
|
|
725 control off on this concentrator (again, refer to your local wizard),
|
|
|
726 you are screwed! You should have the terminal or concentrator
|
|
|
727 replaced with a properly designed one. In the mean time, some drastic
|
|
|
728 measures can make Emacs semi-work.
|
|
|
729
|
|
|
730 You can make Emacs ignore C-s and C-q and let the operating system
|
|
|
731 handle them. To do this on a per-session basis, just type M-x
|
|
|
732 enable-flow-control RET. You will see a message that C-\ and C-^ are
|
|
|
733 now translated to C-s and C-q. (Use the same command M-x
|
|
|
734 enable-flow-control to turn *off* this special mode. It toggles flow
|
|
|
735 control handling.)
|
|
|
736
|
|
|
737 If C-\ and C-^ are inconvenient for you (for example, if one of them
|
|
|
738 is the escape character of your terminal concentrator), you can choose
|
|
|
739 other characters by setting the variables flow-control-c-s-replacement
|
|
|
740 and flow-control-c-q-replacement. But choose carefully, since all
|
|
|
741 other control characters are already used by emacs.
|
|
|
742
|
|
|
743 IMPORTANT: if you type C-s by accident while flow control is enabled,
|
|
|
744 Emacs output will freeze, and you will have to remember to type C-q in
|
|
|
745 order to continue.
|
|
|
746
|
|
|
747 If you work in an environment where a majority of terminals of a
|
|
|
748 certain type are flow control hobbled, you can use the function
|
|
|
749 `enable-flow-control-on' to turn on this flow control avoidance scheme
|
|
|
750 automatically. Here is an example:
|
|
|
751
|
|
|
752 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")
|
|
|
753
|
|
|
754 If this isn't quite correct (e.g. you have a mixture of flow-control hobbled
|
|
|
755 and good vt200 terminals), you can still run enable-flow-control
|
|
|
756 manually.
|
|
|
757
|
|
|
758 I have no intention of ever redesigning the Emacs command set for the
|
|
|
759 assumption that terminals use C-s/C-q flow control. XON/XOFF flow
|
|
|
760 control technique is a bad design, and terminals that need it are bad
|
|
|
761 merchandise and should not be purchased. Now that X is becoming
|
|
|
762 widespread, XON/XOFF seems to be on the way out. If you can get some
|
|
|
763 use out of GNU Emacs on inferior terminals, more power to you, but I
|
|
|
764 will not make Emacs worse for properly designed systems for the sake
|
|
|
765 of inferior systems.

767 *** Control-S and Control-Q commands are ignored completely.
|
|
0
|
768
|
|
|
769 For some reason, your system is using brain-damaged C-s/C-q flow
|
|
|
770 control despite Emacs's attempts to turn it off. Perhaps your
|
|
|
771 terminal is connected to the computer through a concentrator
|
|
|
772 that wants to use flow control.
|
|
|
773
|
|
|
774 You should first try to tell the concentrator not to use flow control.
|
|
|
775 If you succeed in this, try making the terminal work without
|
|
|
776 flow control, as described in the preceding section.
|
|
|
777
|
|
|
778 If that line of approach is not successful, map some other characters
|
|
|
779 into C-s and C-q using keyboard-translate-table. The example above
|
|
|
780 shows how to do this with C-^ and C-\.

785 Some versions of rlogin (and possibly telnet) do not pass flow
|
|
|
786 control characters to the remote system to which they connect.
|
|
|
787 On such systems, emacs on the remote system cannot disable flow
|
|
|
788 control on the local system.
|
|
|
789
|
|
|
790 One way to cure this is to disable flow control on the local host
|
|
|
791 (the one running rlogin, not the one running rlogind) using the
|
|
|
792 stty command, before starting the rlogin process. On many systems,
|
|
120
|
793 `stty start u stop u' will do this.
|
|
0
|
794
|
|
|
795 Some versions of tcsh will prevent even this from working. One way
|
|
|
796 around this is to start another shell before starting rlogin, and
|
|
|
797 issue the stty command to disable flow control from that shell.
|
|
|
798
|
|
|
799 If none of these methods work, the best solution is to type
|
|
120
|
800 `M-x enable-flow-control' at the beginning of your emacs session, or
|
|
0
|
801 if you expect the problem to continue, add a line such as the
|
|
|
802 following to your .emacs (on the host running rlogind):
|
|
|
803
|
|
|
804 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")

|
|
197
|
810
|
|
|
811 XEmacs has fairly new TTY redisplay support (beginning from 19.12),
|
|
|
812 which doesn't include some basic TTY optimizations -- like using
|
|
|
813 scrolling regions to move around blocks of text. This is why
|
|
|
814 redisplay on the traditional terminals, or over slow lines can be very
|
|
|
815 slow.

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

825

826 The first step in tracking this down is to record what characters
|
|
|
827 Emacs is sending to the terminal. Execute the Lisp expression
|
|
120
|
828 (open-termscript "./emacs-script") to make Emacs write all terminal
|
|
|
829 output into the file ~/emacs-script as well; then do what makes the
|
|
|
830 screen update wrong, and look at the file and decode the characters
|
|
|
831 using the manual for the terminal. There are several possibilities:
|
|
0
|
832
|
|
|
833 1) The characters sent are correct, according to the terminal manual.
|
|
|
834
|
|
|
835 In this case, there is no obvious bug in Emacs, and most likely you
|
|
|
836 need more padding, or possibly the terminal manual is wrong.
|
|
|
837
|
|
120
|
838 2) The characters sent are incorrect, due to an obscure aspect of the
|
|
|
839 terminal behavior not described in an obvious way by termcap.
|
|
0
|
840
|
|
120
|
841 This case is hard. It will be necessary to think of a way for Emacs
|
|
|
842 to distinguish between terminals with this kind of behavior and other
|
|
|
843 terminals that behave subtly differently but are classified the same
|
|
|
844 by termcap; or else find an algorithm for Emacs to use that avoids the
|
|
|
845 difference. Such changes must be tested on many kinds of terminals.

908 *** Inability to send an Alt-modified key, when Emacs is communicating
|
|
|
909 directly with an X server.
|
|
|
910
|
|
|
911 If you have tried to bind an Alt-modified key as a command, and it
|
|
|
912 does not work to type the command, the first thing you should check is
|
|
|
913 whether the key is getting through to Emacs. To do this, type C-h c
|
|
|
914 followed by the Alt-modified key. C-h c should say what kind of event
|
|
|
915 it read. If it says it read an Alt-modified key, then make sure you
|
|
|
916 have made the key binding correctly.
|
|
|
917
|
|
|
918 If C-h c reports an event that doesn't have the Alt modifier, it may
|
|
|
919 be because your X server has no key for the Alt modifier. The X
|
|
|
920 server that comes from MIT does not set up the Alt modifier by
|
|
|
921 default.
|
|
|
922
|
|
|
923 If your keyboard has keys named Alt, you can enable them as follows:
|
|
|
924
|
|
|
925 xmodmap -e 'add mod2 = Alt_L'
|
|
|
926 xmodmap -e 'add mod2 = Alt_R'
|
|
|
927
|
|
|
928 If the keyboard has just one key named Alt, then only one of those
|
|
|
929 commands is needed. The modifier `mod2' is a reasonable choice if you
|
|
|
930 are using an unmodified MIT version of X. Otherwise, choose any
|
|
|
931 modifier bit not otherwise used.
|
|
|
932
|
|
|
933 If your keyboard does not have keys named Alt, you can use some other
|
|
|
934 keys. Use the keysym command in xmodmap to turn a function key (or
|
|
|
935 some other 'spare' key) into Alt_L or into Alt_R, and then use the
|
|
|
936 commands show above to make them modifier keys.
|
|
|
937
|
|
|
938 Note that if you have Alt keys but no Meta keys, Emacs translates Alt
|
|
|
939 into Meta. This is because of the great importance of Meta in Emacs.

941 *** In Shell mode, you get a ^M at the end of every line.
|
|
|
942
|
|
|
943 This happens to people who use tcsh, because it is trying to be too
|
|
|
944 smart. It sees that the Shell uses terminal type `unknown' and turns
|
|
|
945 on the flag to output ^M at the end of each line. You can fix the
|
|
|
946 problem by adding this to your .cshrc file:
|
|
|
947
|
|
|
948 if ($?EMACS) then
|
|
|
949 if ($EMACS == "t") then
|

958 This comes from having an invalid X resource, such as

965 *** Once you pull down a menu from the menubar, it won't go away.
|
|
|
966
|
|
|
967 It has been claimed that this is caused by a bug in certain very old
|
|
|
968 (1990?) versions of the twm window manager. It doesn't happen with
|
|
|
969 recent vintages, or with other window managers.

971 *** Emacs ignores the "help" key when running OLWM.
|
|
|
972
|
|
|
973 OLWM grabs the help key, and retransmits it to the appropriate client
|
|
|
974 using XSendEvent. Allowing emacs to react to synthetic events is a
|
|
|
975 security hole, so this is turned off by default. You can enable it by
|
|
|
976 setting the variable x-allow-sendevents to t. You can also cause fix
|
|
|
977 this by telling OLWM to not grab the help key, with the null binding
|
|
|
978 "OpenWindows.KeyboardCommand.Help:".

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

981 terminal type.
|
|
|
982
|
|
|
983 The cause of this is a shell startup file that sets the TERMCAP
|
|
|
984 environment variable. The terminal emulator uses that variable to
|
|
|
985 provide the information on the special terminal type that Emacs
|
|
|
986 emulates.
|
|
|
987
|
|
|
988 Rewrite your shell startup file so that it does not change TERMCAP
|
|
|
989 in such a case. You could use the following conditional which sets
|
|
|
990 it only if it is undefined.
|
|
|
991
|
|
|
992 if ( ! ${?TERMCAP} ) setenv TERMCAP ~/my-termcap-file
|
|
|
993
|
|
|
994 Or you could set TERMCAP only when you set TERM--which should not
|
|
|
995 happen in a non-login shell.

1063 you have probably compiled using an ANSI C compiler, but with non-ANSI

1064 include files. In particular, on Suns, the file
|
|
|
1065 /usr/include/sun/audioio.h uses the _IOW macro to define the constant
|
|
|
1066 AUDIOSETQSIZE. _IOW in turn uses a K&R preprocessor feature that is
|
|
|
1067 now explicitly forbidden in ANSI preprocessors, namely substitution
|
|
|
1068 inside character constants. All ANSI C compilers must provide a
|
|
|
1069 workaround for this problem. Lucid's C compiler is shipped with a new
|
|
|
1070 set of system include files. If you are using GCC, there is a script
|
|
|
1071 called fixincludes that creates new versions of some system include

1106
|
|
|
1107 Be sure also to edit x/config/cf/sun.cf so that OSMinorVersion is 4
|
|
|
1108 (as it should be for Solaris 2.4). The file has three definitions for
|
|
|
1109 OSMinorVersion: the first is for x86, the second for SPARC under

1110 Solaris, and the third for SunOS 4. Make sure to update the

1111 definition for your type of machine and system.

1112
|
|
|
1113 Then do `make Everything' in the top directory of X11R6, to rebuild

|

0
|
1139
|
|
124
|
1140 Many emacs mail user agents (VM and rmail, for instance) use the
|
|
|
1141 sendmail.el library. This library can arrange for mail to be
|
|
|
1142 delivered by passing messages to the /usr/lib/sendmail (usually)
|
|
|
1143 program . In doing so, it passes the '-t' flag to sendmail, which
|
|
|
1144 means that the name of the recipient of the message is not on the
|
|
|
1145 command line and, therefore, that sendmail must parse the message to
|
|
|
1146 obtain the destination address.
|
|
|
1147
|
|
|
1148 There is a bug in the SunOS4.1.1 and SunOS4.1.3 versions of sendmail.
|
|
|
1149 In short, when given the -t flag, the SunOS sendmail won't recognize
|
|
|
1150 non-local (i.e. NIS) aliases. It has been reported that the Solaris
|
|
|
1151 2.x versions of sendmail do not have this bug. For those using SunOS
|
|
|
1152 4.1, the best fix is to install sendmail V8 or IDA sendmail (which
|
|
|
1153 have other advantages over the regular sendmail as well). At the time
|
|
|
1154 of this writing, these official versions are available:
|
|
|
1155
|
|
|
1156 Sendmail V8 on ftp.cs.berkeley.edu in /ucb/sendmail:
|
|
|
1157 sendmail.8.6.9.base.tar.Z (the base system source & documentation)

1169
|
|
124
|
1170 This typically happens on Suns and other systems that use shared
|
|
|
1171 libraries. The cause is that the site has installed a version of the
|
|
|
1172 shared library which uses a name server--but has not installed a
|
|
|
1173 similar version of the unshared library which Emacs uses.
|
|
0
|
1174
|
|
124
|
1175 The result is that most programs, using the shared library, work with
|
|
|
1176 the nameserver, but Emacs does not.
|
|
|
1177
|
|
|
1178 The fix is to install an unshared library that corresponds to what you
|
|
|
1179 installed in the shared library, and then relink Emacs.

|
|
|
1183 If you have already installed the name resolver in the file libresolv.a,
|
|
|
1184 then you need to compile Emacs to use that library. The easiest way to
|
|
|
1185 do this is to add to config.h a definition of LIBS_SYSTEM, LIBS_MACHINE
|
|
|
1186 or LIB_STANDARD which uses -lresolv. Watch out! If you redefine a macro
|
|
|
1187 that is already in use in your configuration to supply some other libraries,
|
|
|
1188 be careful not to lose the others.
|
|
|
1189
|
|
|
1190 Thus, you could start by adding this to config.h:
|
|
|
1191
|
|
|
1192 #define LIBS_SYSTEM -lresolv
|
|
|
1193
|
|
|
1194 Then if this gives you an error for redefining a macro, and you see that
|
|
|
1195 the s- file defines LIBS_SYSTEM as -lfoo -lbar, you could change config.h
|
|
|
1196 again to say this:
|
|
|
1197
|
|
|
1198 #define LIBS_SYSTEM -lresolv -lfoo -lbar

|

1203 On SunOS systems, this problem has been seen to be a result of an

1204 incomplete installation of gcc 2.2 which allowed some non-ANSI

1212 If you build with `gpm' support on Linux, you cannot suspend XEmacs
|

1220 One user on a Linux system reported that this problem went away with

1227 startup takes 10 to 15 seconds longer than `usual'.
|
|
|
1228
|
|
|
1229 This is because Emacs looks up the host name when it starts.
|
|
|
1230 Normally, this takes negligible time; the extra delay is due to
|

1231 improper system configuration. This problem can occur for both

|

1256
|

1257 The solution described in the networked case applies here as well.
|
|
|
1258 However, if you never intend to network your machine, you can use a
|
|
|
1259 simpler solution: create an empty `/etc/host.conf' file. The command
|
|
|
1260 `touch /etc/host.conf' suffices to create the file. The `/etc/hosts'

1261 file is not necessary with this approach.

1268 SGI ships a really old Xpm library in /usr/lib which does not work at

1271 --site-libraries flags to tell configure where to find it.

|

1298 with large compilation buffers.
|
|
|
1299
|
|
|
1300 The default stack size under Digital Unix is rather small (2M as
|
|
|
1301 opposed to Solaris 8M), hosing the regexp code, which uses alloca()
|
|
|
1302 extensively, overflowing the stack when complex regexps are used.

|
|
1303 Workarounds:
|
|
0
|
1304
|
|
312
|
1305 1) Increase your stack size, using `ulimit -s 8192' or a (t)csh
|
|
|
1306 equivalent;
|

|
1307

1310 *** The `Alt' key doesn't behave as `Meta' when running DECwindows.
|
|
|
1311
|
|
|
1312 The default DEC keyboard mapping has the Alt keys set up to generate the
|
|
|
1313 keysym `Multi_key', which has a meaning to xemacs which is distinct from that
|
|
|
1314 of the `Meta_L' and `Meta-R' keysyms. A second problem is that certain keys
|
|
|
1315 have the Mod2 modifier attached to them for no adequately explored reason.
|
|
|
1316 The correct fix is to pass this file to xmodmap upon starting X:
|
|
|
1317
|
|
|
1318 clear mod2
|
|
|
1319 keysym Multi_key = Alt_L

1332 On Ultrix, if you use any of the functions which look up information
|
|
|
1333 in the passwd database before dumping Emacs (say, by using
|
|
|
1334 expand-file-name in site-init.el), then those functions will not work
|
|
|
1335 in the dumped Emacs on any host but the one Emacs was dumped on.
|
|
|
1336
|
|
|
1337 The solution? Don't use expand-file-name in site-init.el, or in
|
|
|
1338 anything it loads. Yuck - some solution.
|
|
|
1339
|
|
|
1340 I'm not sure why this happens; if you can find out exactly what is
|
|
|
1341 going on, and perhaps find a fix or a workaround, please let us know.
|
|
|
1342 Perhaps the YP functions cache some information, the cache is included
|

1343 in the dumped Emacs, and is then inaccurate on any other host.

|
|
|
1348 but I haven't changed anything.
|
|
|
1349
|
|
|
1350 The default HP keymap is set up to have Mod1 assigned to two different keys:
|
|
|
1351 Meta_L and Mode_switch (even though there is not actually a Mode_switch key on
|
|
|
1352 the keyboard -- it uses an "imaginary" keycode.) There actually is a reason
|
|
|
1353 for this, but it's not a good one. The correct fix is to execute this command
|
|
|
1354 upon starting X:
|
|
|
1355
|
|
|
1356 xmodmap -e 'remove mod1 = Mode_switch'

1402 On HP-UX, you can get that error when the Emacs executable is on an NFS

1412
|
|
|
1413 The problem is that in your .cshrc you have something that tries to
|
|
197
|
1414 execute `tty`. If you are not running the shell on a real tty then tty
|
|
|
1415 will print "not a tty". Csh expects one word in some places, but tty

|
1416 is giving it back 3.
|
|
124
|
1417
|
|
197

1418 The solution is to add a pair of quotes around `tty` to make it a
|
|
|
1419 single word:
|
|
0
|
1420
|
|
124

1421 if (`tty` == "/dev/console")

1457
|
|
124
|
1458 There are a few incompatible changes in XEmacs, and these are the
|
|
|
1459 symptoms. Some of the emacs-lisp code you are running needs to be
|
|
|
1460 updated to be compatible with XEmacs.
|
|
|
1461
|
|
|
1462 The code should not treat keymaps as arrays (use `define-key', etc.),
|
|
|
1463 should not use obsolete variables like `unread-command-char' (use
|
|
197
|
1464 `unread-command-events'). Many (most) of the new ways of doing things
|

124

1467 Modern Emacs packages (Gnus, VM, W3, efs, etc) are written to support
|
|
|
1468 GNU Emacs and XEmacs. We have provided modified versions of several
|
|
|
1469 popular emacs packages (dired, etc) which are compatible with this
|
|
|
1470 version of emacs. Check to make sure you have not set your load-path
|
|
|
1471 so that your private copies of these packages are being found before
|
|
|
1472 the versions in the lisp directory.

|
|
|
1474 Make sure that your load-path and your $EMACSLOADPATH environment

1504 ** A reminder: XEmacs/Mule work does not currently receive *any*
|

1505 funding, and all work is done by volunteers. If you think you can

1508 ** XEmacs/Mule doesn't support TTY's satisfactorily.
|
|
223
|
1509
|
|
|
1510 This is a major problem, which we plan to address in a future release
|
|
|
1511 of XEmacs. Basically, XEmacs should have primitives to be told
|
|
|
1512 whether the terminal can handle international output, and which
|
|
|
1513 locale. Also, it should be able to do approximations of characters to
|
|
|
1514 the nearest supported by the locale.

|

|
1516 ** Internationalized (Asian) Isearch doesn't work.
|
|
144
|
1517
|
|
|
1518 Currently, Isearch doesn't directly support any of the input methods
|
|
|
1519 that are not XIM based (like egg, canna and quail) (and there are
|
|
223
|
1520 potential problems with XIM version too...). If you're using egg
|
|
|
1521 there is a workaround. Hitting <RET> right after C-s to invoke
|
|
|
1522 Isearch will put Isearch in string mode, where a complete string can
|
|
|
1523 be typed into the minibuffer and then processed by Isearch afterwards.
|
|
|
1524 Since egg is now supported in the minibuffer using string mode you can
|
|
|
1525 now use egg to input your Japanese, Korean or Chinese string, then hit
|
|
|
1526 return to send that to Isearch and then use standard Isearch commands
|
|
|
1527 from there.

1531
|
|
|
1532 Don't do this. The fence modes of egg and canna are currently very
|
|
|
1533 modal, and messing with where they expect point to be and what they
|
|
|
1534 think is the current buffer is just asking for trouble. If you're
|
|
|
1535 lucky they will realize that something is awry, and simply delete the
|
|
|
1536 fence, but worst case can trash other buffers too. We've tried to
|
|
|
1537 protect against this where we can, but there still are many ways to
|
|
|
1538 shoot yourself in the foot. So just finish what you are typing into
|
|
|
1539 the fence before reaching for the mouse.
