5 This file is large, but we have tried to sort the entries by their
|
|
|
6 respective relevance for XEmacs, but may have not succeeded completely
|
|
|
7 in that task. Try finding the things you need using one of the search
|
|
|
8 commands XEmacs provides (e.g. `C-s').

12 * Watch out for .emacs file
|
|
|
13
|
|
|
14 ~/.emacs is your Emacs init file. If you observe strange problems,
|
|
|
15 invoke XEmacs with the `-q' option and see if you can repeat the
|
|
|
16 problem.

22 Are you using an ANSI C compiler, like lcc or gcc? The SunOS 4.1 bundled cc
|
|
|
23 is not ANSI.
|
|
|
24
|
|
|
25 If X has not been configured to compile itself using lcc, gcc, or another ANSI
|
|
|
26 compiler, then you will have to hack the automatically-generated makefile in
|
|
|
27 the `lwlib' directory by hand to make it use an ANSI compiler.

|
|
34 This can be because the .elc files have been garbled. Do not be
|
|
|
35 fooled by the fact that most of a .elc file is text: these are
|
|
|
36 binary files and can contain all 256 byte values.
|
|
|
37
|
|
|
38 In particular `shar' cannot be used for transmitting GNU Emacs.
|
|
|
39 It typically truncates "lines". What appear to be "lines" in
|
|
|
40 a binary file can of course be of any length. Even once `shar'
|
|
|
41 itself is made to work correctly, `sh' discards null characters
|
|
|
42 when unpacking the shell archive.
|
|
|
43
|
|
|
44 I have also seen character \177 changed into \377. I do not know
|
|
|
45 what transfer means caused this problem. Various network
|
|
|
46 file transfer programs are suspected of clobbering the high bit.
|
|
|
47
|
|
|
48 If you have a copy of Emacs that has been damaged in its
|
|
|
49 nonprinting characters, you can fix them:
|
|
|
50
|
|
|
51 1) Record the names of all the .elc files.
|
|
|
52 2) Delete all the .elc files.
|
|
|
53 3) Recompile alloc.c with a value of PURESIZE twice as large.
|
|
|
54 You might as well save the old alloc.o.
|
|
|
55 4) Remake xemacs. It should work now.
|
|
|
56 5) Running xemacs, do Meta-x byte-compile-file repeatedly
|
|
|
57 to recreate all the .elc files that used to exist.
|
|
|
58 You may need to increase the value of the variable
|
|
|
59 max-lisp-eval-depth to succeed in running the compiler interpreted
|
|
|
60 on certain .el files. 400 was sufficient as of last report.
|
|
|
61 6) Reinstall the old alloc.o (undoing changes to alloc.c if any)
|
|
|
62 and remake temacs.
|
|
|
63 7) Remake xemacs. It should work now, with valid .elc files.
|
|
|
64
|
|
124
|
65 ** temacs prints "Pure Lisp storage exhausted"
|
|
0
|
66
|
|
|
67 This means that the Lisp code loaded from the .elc and .el
|
|
|
68 files during temacs -l loadup inc dump took up more
|
|
|
69 space than was allocated.
|
|
|
70
|
|
|
71 This could be caused by
|
|
|
72 1) adding code to the preloaded Lisp files
|
|
|
73 2) adding more preloaded files in loadup.el
|
|
|
74 3) having a site-init.el or site-load.el which loads files.
|
|
|
75 Note that ANY site-init.el or site-load.el is nonstandard;
|
|
|
76 if you have received Emacs from some other site
|
|
|
77 and it contains a site-init.el or site-load.el file, consider
|
|
|
78 deleting that file.
|
|
|
79 4) getting the wrong .el or .elc files
|
|
|
80 (not from the directory you expected).
|
|
|
81 5) deleting some .elc files that are supposed to exist.
|
|
|
82 This would cause the source files (.el files) to be
|
|
|
83 loaded instead. They take up more room, so you lose.
|
|
|
84 6) a bug in the Emacs distribution which underestimates
|
|
|
85 the space required.
|
|
|
86
|
|
|
87 If the need for more space is legitimate, use the --puresize option
|
|
|
88 to `configure' to specify more pure space.
|
|
|
89
|
|
|
90 But in some of the cases listed above, this problem is a consequence
|
|
|
91 of something else that is wrong. Be sure to check and fix the real
|
|
|
92 problem.

94 ** Don't use -O2 with gcc 2.7.2 under Linux without also using

96
|
|
|
97 gcc will generate incorrect code otherwise. This bug is present in at
|
|
|
98 least 2.6.x and 2.7.[0-2]. This bug has been fixed in GCC 2.7.2.1 and
|
|
|
99 later.

106 ** Movemail on Linux doesn't work any more
|

107

108 Linux now defaults to using .lock mail locking. To get back to the
|
|
|
109 previous flock locking, edit src/s/linux.h and uncomment out the

110 `# define MAIL_USE_FLOCK' line.

112 ** Sparc Linux -vs- libXmu.
|
|
|
113
|
|
|
114 There have been reports of configure not detecting libXmu on
|
|
|
115 SparcLinux. The fix is to add -lXmu to the link flags.
|
|
|
116
|
|
|
117 ** Debian Linux and Berkeley db include files.
|
|
|
118
|
|
|
119 Debian Linux puts the Berkeley db include files in /usr/include/db
|
|
|
120 instead of /usr/include. The fix is to use
|
|
|
121 --site-includes=/usr/include/db with configure.

132 It has been reported on some systems that compiling with -O6 can lead

152

153 There have been reports of Sun sed truncating very lines in the

154 Makefile during configuration. The workaround is to use GNU sed or,
|
|
|
155 even better, think of a better way to generate Makefile, and send us a
|
|
|
156 patch. :-)

161 I have to force /usr/dt/{lib,include} into the site include/lib

|
|

163 would think these should be pretty standard (to my knowledge, that's
|
|
|
164 also where Sun puts its CDE stuff), so that wouldn't fix the problem
|
|
|
165 on other architectures. AAMOF, when these path are given, CDE is
|
|

166 detected, and DragAndDrop works (more or less, see next issue).

168 ** Linking with -rpath on IRIX.
|
|
|
169
|
|
|
170 Darrell Kindred <dkindred@cmu.edu> writes:
|
|
|
171 There are a couple of problems [with use of -rpath with Irix ld], though:
|
|
|
172
|
|
|
173 1. The ld in IRIX 5.3 ignores all but the last -rpath
|
|
|
174 spec, so the patched configure spits out a warning
|
|
|
175 if --x-libraries or --site-runtime-libraries are
|
|
|
176 specified under irix 5.x, and it only adds -rpath
|
|
|
177 entries for the --site-runtime-libraries. This bug was
|
|
|
178 fixed sometime between 5.3 and 6.2.
|
|
|
179
|
|
|
180 2. IRIX gcc 2.7.2 doesn't accept -rpath directly, so
|
|
|
181 it would have to be prefixed by -Xlinker or "-Wl,".
|
|
|
182 This would be fine, except that configure compiles with
|
|
|
183 ${CC-cc} $CFLAGS $LDFLAGS ...
|
|
|
184 rather than quoting $LDFLAGS with prefix-args, like
|
|
|
185 src/Makefile does. So if you specify --x-libraries
|
|
|
186 or --site-runtime-libraries, you must use --use-gcc=no,
|
|
|
187 or configure will fail.
|
|

|
189 ** On Irix 5.x and 6.x, the dumped XEmacs (xemacs) core dumps when executed
|
|
|
190 on another machine, or after newer SGI IRIX patches have been installed.
|
|
|
191
|
|
|
192 The xemacs binary must be executed with the same "libc.so" file which
|
|
|
193 was used when the xemacs binary was dumped. Some SGI IRIX patches
|
|
|
194 update this file. Make sure that all machines using the xemacs binary
|
|
|
195 are using the same set of IRIX patches. If xemacs core dumps after a
|
|
|
196 patch upgrade then you will have to redump it from temacs.

197
|
|
|
198 ** xemacs: can't resolve symbol '__malloc_hook'
|
|
|
199
|
|
|
200 This is a Linux problem where you've compiled the XEmacs binary on a libc
|
|
|
201 5.4 with version higher than 5.4.19 and attempted to run the binary against
|
|
|
202 an earlier version. The solution is to upgrade your old library.
|
|
|
203
|
|
|
204 ** Compilation errors on VMS.
|
|
|
205
|
|
|
206 Sorry, XEmacs does not work under VMS. You might consider working on
|
|
|
207 the port if you really want to have XEmacs work under VMS.
|
|
|
208
|
|
|
209 ** On HP/UX configure selects gcc even though it isn't actually present.
|
|
|
210
|
|
|
211 Some versions of SoftBench have an executable called 'gcc' that is not
|
|
|
212 actually the GNU C compiler. Use the --with-gcc=no flag when running
|
|
|
213 configure.
|
|
|
214
|
|
|
215 ** On Solaris 2.* I get undefined symbols from libcurses.a.
|
|
|
216
|
|
|
217 You probably have /usr/ucblib/ on your LD_LIBRARY_PATH. Do the link with
|
|
|
218 LD_LIBRARY_PATH unset.
|
|
|
219
|
|
|
220 ** On Solaris 2.* I cannot make alloc.o, glyphs.o or process.o.
|
|
|
221
|
|
|
222 The SparcWorks C compiler may have difficulty building those modules
|
|
|
223 with optimization level -xO4. Try using only "-fast" optimization
|
|
|
224 for just those modules. (Or use gcc).
|
|
|
225
|
|
|
226 ** On Digital UNIX, the DEC C compiler might have a problem compiling
|
|
|
227 some files.
|
|
|
228
|
|
|
229 In particular, src/extents.c and src/faces.c might cause the DEC C
|
|
|
230 compiler to abort. When this happens: cd src, compile the files by
|
|
|
231 hand, cd .., and redo the "make" command. When recompiling the files by
|
|
|
232 hand, use the old C compiler for the following versions of Digital UNIX:
|
|
|
233 - V3.n: Remove "-migrate" from the compile command.
|
|
|
234 - V4.n: Add "-oldc" to the compile command.

|
236 ** On Digital UNIX, TOOLTALK gets misdetected and misconfigured

239 LIB_TOOLTALK string into the Makefile.

|
|
|
251 haven't found the same patch for hpux 10.10, and I don't

252 remember the patch numbers. I think potential XEmacs builders

253 on HP should be warned about this.

260 ** Solaris 2.3 /bin/sh coredumps during configuration.
|

261

262 This only occurs if you have LANG != C. This is a known bug with

273 ** Native cc on SCO OpenServer 5 is now OK. Icc may still throw you
|
|
|
274 a curve. Here is what Robert Lipe <robertl@arnet.com> says:
|
|
|
275
|
|
|
276 Unlike XEmacs 19.13, building with the native cc on SCO OpenServer 5
|
|
|
277 now produces a functional binary. I will typically build this
|
|
|
278 configuration for COFF with:
|
|
|
279
|
|
|
280 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
|
281 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
282 --with-xpm --with-xface --with-sound=nas
|
|
|
283
|
|
|
284 This version now supports ELF builds. I highly recommend this to
|
|
|
285 reduce the in-core footprint of XEmacs. This is now how I compile
|
|
|
286 all my test releases. Build it like this:
|
|
|
287
|
|
|
288 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
|
289 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
290 --with-xpm --with-xface --with-sound=nas --dynamic
|
|
|
291
|
|
|
292 The compiler known as icc [ supplied with the OpenServer 5 Development
|
|
|
293 System ] generates a working binary, but it takes forever to generate
|
|
|
294 XEmacs. ICC also whines more about the code than /bin/cc does. I do
|
|
|
295 believe all its whining is legitimate, however. Note that you do
|
|
|
296 have to 'cd src ; make LD=icc' to avoid linker errors.
|
|
|
297
|
|
|
298 The way I handle the build procedure is:
|
|
|
299
|
|
|
300 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
|
301 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
302 --with-xpm --with-xface --with-sound=nas --dynamic --compiler="icc"
|
|
|
303
|
|
|
304 NOTE I have the xpm, xface, and audio libraries and includes in
|
|
|
305 /usr/local/lib, /usr/local/include. If you don't have these,
|
|
|
306 don't include the "--with-*" arguments in any of my examples.
|
|
|
307
|
|
|
308 In previous versions of XEmacs, you had to override the defaults while
|
|
|
309 compiling font-lock.o and extents.o when building with icc. This seems
|
|
|
310 to no longer be true, but I'm including this old information in case it
|
|
|
311 resurfaces. The process I used was:
|
|
|
312
|
|
|
313 make -k
|
|
|
314 [ procure pizza, beer, repeat ]
|
|
|
315 cd src
|
|
|
316 make CC="icc -W0,-mP1COPT_max_tree_size=3000" font-lock.o extents.o
|
|
|
317 make LD=icc
|
|
|
318
|
|
|
319 If you want sound support, get the tls566 supplement from
|
|
|
320 ftp.sco.com:/TLS or any of its mirrors. It works just groovy
|
|
|
321 with XEmacs.

323 The M-x manual-entry is known not to work. If you know Lisp and would
|
|
|
324 like help in making it work, e-mail me at <robertl@dgii.com>.
|
|
|
325 (UNCHECKED for 19.15 -- it might work).
|
|
|
326
|
|
|
327 In earlier releases, gnuserv/gnuclient/gnudoit would open a frame
|
|
|
328 just fine, but the client would lock up and the server would
|
|
|
329 terminate when you used C-x # to close the frame. This is now
|
|
|
330 fixed in XEmacs.
|
|
|
331
|
|
|
332 In etc/ there are two files of note. emacskeys.sco and emacsstrs.sco.
|
|
|
333 The comments at the top of emacskeys.sco describe its function, and
|
|
|
334 the emacstrs.sco is a suitable candidate for /usr/lib/keyboard/strings
|
|
|
335 to take advantage of the keyboard map in emacskeys.sco.
|
|
|
336
|
|
|
337 ** Under some versions of OSF XEmacs runs fine if built without
|
|
|
338 optimization but will crash randomly if built with optimization.
|
|
|
339
|
|
|
340 Using 'cc -g' is not sufficient to eliminate all optimization. Try
|
|
|
341 'cc -g -O0' instead.

343 ** On SunOS, you get linker errors
|
|
|
344 ld: Undefined symbol
|
|
|
345 _get_wmShellWidgetClass
|
|
|
346 _get_applicationShellWidgetClass
|
|
|
347
|
|
|
348 The fix to this is to install patch 100573 for OpenWindows 3.0
|
|
|
349 or link libXmu statically.
|
|
|
350
|
|
|
351 ** On Sunos 4, you get the error ld: Undefined symbol __lib_version.
|
|
|
352
|
|
|
353 This is the result of using cc or gcc with the shared library meant
|
|
|
354 for acc (the Sunpro compiler). Check your LD_LIBRARY_PATH and delete
|
|
|
355 /usr/lang/SC2.0.1 or some similar directory.
|
|
|
356
|
|
|
357 ** On AIX 4.1.2, linker error messages such as
|
|
|
358 ld: 0711-212 SEVERE ERROR: Symbol .__quous, found in the global symbol table
|
|
|
359 of archive /usr/lib/libIM.a, was not defined in archive member shr.o.
|
|
|
360
|
|
|
361 This is a problem in libIM.a. You can work around it by executing
|
|
|
362 these shell commands in the src subdirectory of the directory where
|
|
|
363 you build Emacs:
|
|
|
364
|
|
|
365 cp /usr/lib/libIM.a .
|
|
|
366 chmod 664 libIM.a
|
|
|
367 ranlib libIM.a
|
|
|
368
|
|
|
369 Then change -lIM to ./libIM.a in the command to link temacs (in
|
|
|
370 Makefile).
|
|
|
371
|
|
|
372 ** On Irix 5.2, unexelfsgi.c can't find cmplrs/stsupport.h.
|
|
|
373
|
|
|
374 The file cmplrs/stsupport.h was included in the wrong file set in the
|
|
|
375 Irix 5.2 distribution. You can find it in the optional fileset
|
|
|
376 compiler_dev, or copy it from some other Irix 5.2 system. A kludgy
|
|
|
377 workaround is to change unexelfsgi.c to include sym.h instead of
|
|
|
378 syms.h.
|
|
|
379
|
|
|
380 ** Link failure when using acc on a Sun.
|
|
|
381
|
|
|
382 To use acc, you need additional options just before the libraries, such as
|
|
|
383
|
|
|
384 /usr/lang/SC2.0.1/values-Xt.o -L/usr/lang/SC2.0.1/cg87 -L/usr/lang/SC2.0.1
|
|
|
385
|
|
|
386 and you need to add -lansi just before -lc.
|
|
|
387
|
|
|
388 The precise file names depend on the compiler version, so we
|
|
|
389 cannot easily arrange to supply them.
|
|
|
390
|
|
|
391 ** Link failure on IBM AIX 1.3 ptf 0013.
|
|
|
392
|
|
|
393 There is a real duplicate definition of the function `_slibc_free' in
|
|
|
394 the library /lib/libc_s.a (just do nm on it to verify). The
|
|
|
395 workaround/fix is:
|
|
|
396
|
|
|
397 cd /lib
|
|
|
398 ar xv libc_s.a NLtmtime.o
|
|
|
399 ar dv libc_s.a NLtmtime.o

|
|
401 ** Undefined symbols _dlopen, _dlsym and/or _dlclose on a Sun.
|
|
|
402
|
|
|
403 If you see undefined symbols _dlopen, _dlsym, or _dlclose when linking
|
|
|
404 with -lX11, compile and link against the file mit/util/misc/dlsym.c in
|
|
|
405 the MIT X11R5 distribution. Alternatively, link temacs using shared
|
|
|
406 libraries with s/sunos4shr.h. (This doesn't work if you use the X
|
|
|
407 toolkit.)
|
|
|
408
|
|
|
409 If you get the additional error that the linker could not find
|
|
|
410 lib_version.o, try extracting it from X11/usr/lib/X11/libvim.a in
|
|
|
411 X11R4, then use it in the link.
|
|
|
412
|
|
|
413 ** Undefined symbols when linking on Sunos 4.1.
|
|
|
414
|
|
|
415 If you get the undefined symbols _atowc _wcslen, _iswprint, _iswspace,
|
|
|
416 _iswcntrl, _wcscpy, and _wcsncpy, then you need to add -lXwchar after
|
|
|
417 -lXaw in the command that links temacs.
|
|
|
418
|
|
|
419 This problem seems to arise only when the international language
|
|
|
420 extensions to X11R5 are installed.
|
|
|
421
|
|
|
422 ** src/Makefile and lib-src/Makefile are truncated--most of the file missing.
|
|
|
423
|
|
|
424 This can happen if configure uses GNU sed version 2.03. That version
|
|
|
425 had a bug. GNU sed version 2.05 works properly.
|
|
|
426
|
|
|
427 ** On AIX, you get this compiler error message:
|
|
|
428

429 Processing include file ./XMenuInt.h
|
|
|
430 1501-106: (S) Include file X11/Xlib.h not found.
|
|
|
431
|
|
|
432 This means your system was installed with only the X11 runtime i.d
|
|
|
433 libraries. You have to find your sipo (bootable tape) and install
|
|
|
434 X11Dev... with smit.

435
|
|
|
436 ** C-z just refreshes the screen instead of suspending Emacs.
|
|
|
437
|
|
|
438 You are probably using a shell that doesn't support job control, even
|
|
|
439 though the system itself is capable of it. Either use a different shell,
|
|
|
440 or set the variable `cannot-suspend' to a non-nil value.
|
|
|
441
|
|
|
442 ** On a Sun running SunOS 4.1.1, you get this error message from GNU ld:
|
|
|
443
|
|
|
444 /lib/libc.a(_Q_sub.o): Undefined symbol __Q_get_rp_rd referenced from text segment
|
|
|
445
|
|
|
446 The problem is in the Sun shared C library, not in GNU ld.
|
|
|
447
|
|
|
448 The solution is to install Patch-ID# 100267-03 from Sun.
|
|
|
449
|
|
|
450 ** SunOS 4.1.2: undefined symbol _get_wmShellWidgetClass
|
|
|
451
|
|
|
452 Apparently the version of libXmu.so.a that Sun ships is hosed: it's missing
|
|
|
453 some stuff that is in libXmu.a (the static version). Sun has a patch for
|
|
|
454 this, but a workaround is to use the static version of libXmu, by changing
|
|
|
455 the link command from "-lXmu" to "-Bstatic -lXmu -Bdynamic". If you have
|
|
|
456 OpenWindows 3.0, ask Sun for these patches:
|
|
|
457 100512-02 4.1.x OpenWindows 3.0 libXt Jumbo patch
|
|
|
458 100573-03 4.1.x OpenWindows 3.0 undefined symbols with shared libXmu

459
|
|
|
460 ** Random other SunOS 4.1.[12] link errors.
|
|
|
461
|
|
|
462 The X headers and libraries that Sun ships in /usr/{include,lib}/X11 are
|
|
|
463 broken. Use the ones in /usr/openwin/{include,lib} instead.

464
|
|
|
465 ** When using gcc, you get the error message "undefined symbol __fixunsdfsi".
|
|
|
466 ** When using gcc, you get the error message "undefined symbol __main".
|
|
|
467
|
|
|
468 This means that you need to link with the gcc library. It may be called
|
|
|
469 "gcc-gnulib" or "libgcc.a"; figure out where it is, and define LIB_GCC in
|
|
|
470 config.h to point to it.
|
|
|
471
|
|
|
472 It may also work to use the GCC version of `ld' instead of the standard one.
|
|
|
473
|
|
|
474 ** When compiling with X11, you get "undefined symbol _XtStrings".
|
|
|
475
|
|
|
476 This means that you are trying to link emacs against the X11r4 version of
|
|
|
477 libXt.a, but you have compiled either Emacs or the code in the lwlib
|
|
|
478 subdirectory with the X11r5 header files. That doesn't work.
|
|
|
479
|
|
|
480 Remember, you can't compile lwlib for r4 and emacs for r5, or vice versa.
|
|
|
481 They must be in sync.

|
483 ** Problems finding X11 libraries on Solaris with Openwindows
|
|
|
484
|
|
|
485 Some users have reported problems in this area. The reported solution
|
|
|
486 is to define the environment variable OPENWINHOME, even if you must set
|
|
|
487 it to `/usr/openwin'.
|
|
|
488
|

124
|
489 * Problems with running XEmacs
|
|
|
490
|
|
|
491 ** You type Control-H (Backspace) expecting to delete characters.
|
|
|
492
|
|
|
493 Emacs has traditionally used Control-H for help; unfortunately this
|
|
|
494 interferes with its use as Backspace on TTY's. One way to solve this
|
|
|
495 problem is to put this in your .emacs:
|
|
|
496
|
|
|
497 (keyboard-translate ?\C-h ?\C-?)
|
|
|
498 (global-set-key "\M-?" 'help-command)
|
|
|
499
|
|
|
500 This makes Control-H (Backspace) work sensibly, and moves help to
|
|
|
501 Meta-? (ESC ?).
|
|
|
502
|
|
|
503 Note that you can probably also access help using F1.
|
|
|
504
|
|
|
505 ** On Solaris, C-x doesn't get through to Emacs when you use the console.
|
|
|
506
|
|
|
507 This is a Solaris feature (at least on Intel x86 cpus). Type C-r
|
|
|
508 C-r C-t, to toggle whether C-x gets through to Emacs.
|
|
|
509
|
|
|
510 ** VM appears to hang in large folders
|
|
|
511
|
|
|
512 This is normal (trust us) when upgrading to VM-6.22 from earlier
|
|
|
513 versions. Let VM finish what it is doing and all will be well.

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

0
|
516
|
|
|
517 You may have forgotten to recompile them into .elc files.
|
|
|
518 Then the old .elc files will be loaded, and your changes
|
|
|
519 will not be seen. To fix this, do M-x byte-recompile-directory
|
|
|
520 and specify the directory that contains the Lisp files.
|
|
|
521
|
|
|
522 Note that you may get a warning when loading a .elc file that
|
|
|
523 is older than the corresponding .el file.

525 ** Things which should be bold or italic (such as the initial copyright notice)
|
|

526 are not.
|

0
|
527
|
|
|
528 The fonts of the "bold" and "italic" faces are generated from the font of
|
|
|
529 the "default" face; in this way, your bold and italic fonts will have the
|
|
|
530 appropriate size and family. However, emacs can only be clever in this
|
|
|
531 way if you have specified the default font using the XLFD (X Logical Font
|
|
|
532 Description) format, which looks like
|
|
|
533
|
|
|
534 *-courier-medium-r-*-*-*-120-*-*-*-*-*-*
|
|
|
535
|
|
|
536 if you use any of the other, less strict font name formats, some of which
|
|
|
537 look like

538 lucidasanstypewriter-12
|
|
|
539 and fixed
|
|
|
540 and 9x13
|
|
|
541
|
|
|
542 then emacs won't be able to guess the names of the "bold" and "italic"
|
|
|
543 versions. All X fonts can be referred to via XLFD-style names, so you
|
|
|
544 should use those forms. See the man pages for X(1), xlsfonts(1), and
|
|
|
545 xfontsel(1).

547 ** The dumped Emacs (XEmacs) crashes when run, trying to write pure data.
|
|
0
|
548
|
|
|
549 Two causes have been seen for such problems.
|
|
|
550
|
|
|
551 1) On a system where getpagesize is not a system call, it is defined
|
|
|
552 as a macro. If the definition (in both unexec.c and malloc.c) is wrong,
|
|
|
553 it can cause problems like this. You might be able to find the correct
|
|
|
554 value in the man page for a.out (5).
|
|
|
555
|
|
|
556 2) Some systems allocate variables declared static among the
|
|
|
557 initialized variables. Emacs makes all initialized variables in most
|
|
|
558 of its files pure after dumping, but the variables declared static and
|
|
|
559 not initialized are not supposed to be pure. On these systems you
|
|
|
560 may need to add "#define static" to the m- or the s- file.
|
|
|
561
|
|
124
|
562 ** Reading and writing files is very very slow.
|
|
0
|
563
|
|
|
564 Try evaluating the form (setq lock-directory nil) and see if that helps.
|
|
|
565 There is a problem with file-locking on some systems (possibly related
|
|
|
566 to NFS) that I don't understand. Please send mail to the address
|
|
|
567 xemacs@xemacs.org if you figure this one out.
|
|
|
568
|
|
124
|
569 ** The Emacs window disappears when you type M-q.
|
|
|
570
|
|
|
571 Some versions of the Open Look window manager interpret M-q as a quit
|
|
|
572 command for whatever window you are typing at. If you want to use
|
|
|
573 Emacs with that window manager, you should try to configure the window
|
|
|
574 manager to use some other command. You can disable the
|
|
|
575 shortcut keys entirely by adding this line to ~/.OWdefaults:
|
|
|
576
|
|
|
577 OpenWindows.WindowMenuAccelerators: False
|
|
|
578
|
|
|
579 ** The `Alt' key doesn't behave as `Meta' when running DECwindows.
|
|
|
580
|
|
|
581 The default DEC keyboard mapping has the Alt keys set up to generate the
|
|
|
582 keysym `Multi_key', which has a meaning to xemacs which is distinct from that
|
|
|
583 of the `Meta_L' and `Meta-R' keysyms. A second problem is that certain keys
|
|
|
584 have the Mod2 modifier attached to them for no adequately explored reason.
|
|
|
585 The correct fix is to pass this file to xmodmap upon starting X:
|
|
|
586
|
|
|
587 clear mod2
|
|
|
588 keysym Multi_key = Alt_L
|
|
|
589 add mod1 = Alt_L
|
|
|
590 add mod1 = Alt_R
|
|
|
591
|
|
|
592 ** The Compose key on a DEC keyboard does not work as Meta key.
|
|
|
593
|
|
|
594 This shell command should fix it:
|
|
|
595
|
|
|
596 xmodmap -e 'keycode 0xb1 = Meta_L'
|
|
|
597
|
|
|
598
|
|
|
599 ** When emacs starts up, I get lots of warnings about unknown keysyms.
|
|
|
600
|
|
|
601 If you are running the prebuilt binaries, the Motif library expects to find
|
|
|
602 certain thing in the XKeysymDB file. This file is normally in /usr/lib/X11/
|
|
|
603 or in /usr/openwin/lib/. If you keep yours in a different place, set the
|
|
|
604 environment variable $XKEYSYMDB to point to it before starting emacs. If
|
|
|
605 you still have the problem after doing that, perhaps your version of X is
|
|
|
606 too old. There is a copy of the MIT X11R5 XKeysymDB file in the emacs `etc'
|
|
|
607 directory. Try using that one.
|
|
|

609 ** My X resources used to work, and now some of them are being ignored.

610
|
|
124
|
611 Check the resources in .../etc/Emacs.ad (which is the same as the file
|
|
|
612 sample.Xdefaults). Perhaps some of the default resources built in to
|
|
|
613 emacs are now overriding your existing resources. Copy and edit the
|

614 resources in Emacs.ad as necessary.

616 ** I get complaints about the mapping of my HP keyboard at startup, but I
|
|
|
617 haven't changed anything.
|
|
|
618
|
|
|
619 The default HP keymap is set up to have Mod1 assigned to two different keys:
|
|
|
620 Meta_L and Mode_switch (even though there is not actually a Mode_switch key on
|
|
|
621 the keyboard -- it uses an "imaginary" keycode.) There actually is a reason
|
|
|
622 for this, but it's not a good one. The correct fix is to execute this command
|
|
|
623 upon starting X:
|
|
|
624
|
|
|
625 xmodmap -e 'remove mod1 = Mode_switch'

629
|
|
|
630 The focus issues with a program like XEmacs, which has multiple homogeneous
|
|
|
631 top-level windows, are very complicated, and as a result, most window managers
|
|
|
632 don't implement them correctly.

647 In older versions of NCDwm, one could not even type at XEmacs windows. This

648 has been fixed in newer versions (2.4.3, and possibly earlier).
|
|
|
649
|
|
|
650 (Many people suggest that XEmacs should warp the mouse when focusing on
|
|
|
651 another screen in point-to-type mode. This is not ICCCM-compliant behavior.
|
|
|
652 Implementing such policy is the responsibility of the window manager itself,
|
|
|
653 it is not legal for a client to do this.)

661 There are two different protocols in general use. One of them uses

|
120
|
664 this. You control which one is used by defining, or not defining, the

|
|
665 macro MAIL_USE_FLOCK in config.h or the m- or s- file it includes. IF

693 ** Emacs spontaneously displays "I-search: " at the bottom of the screen.
|
|
0
|
694
|
|
|
695 This means that Control-S/Control-Q (XON/XOFF) "flow control" is being
|
|
|
696 used. C-s/C-q flow control is bad for Emacs editors because it takes
|
|
|
697 away C-s and C-q as user commands. Since editors do not output long
|
|
|
698 streams of text without user commands, there is no need for a
|
|
|
699 user-issuable "stop output" command in an editor; therefore, a
|
|
|
700 properly designed flow control mechanism would transmit all possible
|
|
|
701 input characters without interference. Designing such a mechanism is
|
|
|
702 easy, for a person with at least half a brain.
|
|
|
703
|
|
|
704 There are three possible reasons why flow control could be taking place:
|
|
|
705
|
|
|
706 1) Terminal has not been told to disable flow control
|
|
|
707 2) Insufficient padding for the terminal in use
|
|
|
708 3) Some sort of terminal concentrator or line switch is responsible
|
|
|
709
|
|
|
710 First of all, many terminals have a set-up mode which controls whether
|
|
|
711 they generate XON/XOFF flow control characters. This must be set to
|
|
|
712 "no XON/XOFF" in order for Emacs to work. Sometimes there is an
|
|
|
713 escape sequence that the computer can send to turn flow control off
|
|
|
714 and on. If so, perhaps the termcap `ti' string should turn flow
|
|
|
715 control off, and the `te' string should turn it on.
|
|
|
716
|
|
|
717 Once the terminal has been told "no flow control", you may find it
|
|
|
718 needs more padding. The amount of padding Emacs sends is controlled
|
|
|
719 by the termcap entry for the terminal in use, and by the output baud
|
|
|
720 rate as known by the kernel. The shell command `stty' will print
|
|
|
721 your output baud rate; `stty' with suitable arguments will set it if
|
|
|
722 it is wrong. Setting to a higher speed causes increased padding. If
|
|
|
723 the results are wrong for the correct speed, there is probably a
|
|
|
724 problem in the termcap entry. You must speak to a local Unix wizard
|
|
|
725 to fix this. Perhaps you are just using the wrong terminal type.
|
|
|
726
|
|
|
727 For terminals that lack a "no flow control" mode, sometimes just
|
|
|
728 giving lots of padding will prevent actual generation of flow control
|
|
|
729 codes. You might as well try it.
|
|
|
730
|
|
|
731 If you are really unlucky, your terminal is connected to the computer
|
|
|
732 through a concentrator which sends XON/XOFF flow control to the
|
|
|
733 computer, or it insists on sending flow control itself no matter how
|
|
|
734 much padding you give it. Unless you can figure out how to turn flow
|
|
|
735 control off on this concentrator (again, refer to your local wizard),
|
|
|
736 you are screwed! You should have the terminal or concentrator
|
|
|
737 replaced with a properly designed one. In the mean time, some drastic
|
|
|
738 measures can make Emacs semi-work.
|
|
|
739
|
|
|
740 You can make Emacs ignore C-s and C-q and let the operating system
|
|
|
741 handle them. To do this on a per-session basis, just type M-x
|
|
|
742 enable-flow-control RET. You will see a message that C-\ and C-^ are
|
|
|
743 now translated to C-s and C-q. (Use the same command M-x
|
|
|
744 enable-flow-control to turn *off* this special mode. It toggles flow
|
|
|
745 control handling.)
|
|
|
746
|
|
|
747 If C-\ and C-^ are inconvenient for you (for example, if one of them
|
|
|
748 is the escape character of your terminal concentrator), you can choose
|
|
|
749 other characters by setting the variables flow-control-c-s-replacement
|
|
|
750 and flow-control-c-q-replacement. But choose carefully, since all
|
|
|
751 other control characters are already used by emacs.
|
|
|
752
|
|
|
753 IMPORTANT: if you type C-s by accident while flow control is enabled,
|
|
|
754 Emacs output will freeze, and you will have to remember to type C-q in
|
|
|
755 order to continue.
|
|
|
756
|
|
|
757 If you work in an environment where a majority of terminals of a
|
|
|
758 certain type are flow control hobbled, you can use the function
|
|
|
759 `enable-flow-control-on' to turn on this flow control avoidance scheme
|
|
|
760 automatically. Here is an example:
|
|
|
761
|
|
|
762 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")
|
|
|
763
|
|
|
764 If this isn't quite correct (e.g. you have a mixture of flow-control hobbled
|
|
|
765 and good vt200 terminals), you can still run enable-flow-control
|
|
|
766 manually.
|
|
|
767
|
|
|
768 I have no intention of ever redesigning the Emacs command set for the
|
|
|
769 assumption that terminals use C-s/C-q flow control. XON/XOFF flow
|
|
|
770 control technique is a bad design, and terminals that need it are bad
|
|
|
771 merchandise and should not be purchased. Now that X is becoming
|
|
|
772 widespread, XON/XOFF seems to be on the way out. If you can get some
|
|
|
773 use out of GNU Emacs on inferior terminals, more power to you, but I
|
|
|
774 will not make Emacs worse for properly designed systems for the sake
|
|
|
775 of inferior systems.

|
|

|
777 ** Control-S and Control-Q commands are ignored completely.
|
|
0
|
778
|
|
|
779 For some reason, your system is using brain-damaged C-s/C-q flow
|
|
|
780 control despite Emacs's attempts to turn it off. Perhaps your
|
|
|
781 terminal is connected to the computer through a concentrator
|
|
|
782 that wants to use flow control.
|
|
|
783
|
|
|
784 You should first try to tell the concentrator not to use flow control.
|
|
|
785 If you succeed in this, try making the terminal work without
|
|
|
786 flow control, as described in the preceding section.
|
|
|
787
|
|
|
788 If that line of approach is not successful, map some other characters
|
|
|
789 into C-s and C-q using keyboard-translate-table. The example above
|
|
|
790 shows how to do this with C-^ and C-\.

795 Some versions of rlogin (and possibly telnet) do not pass flow
|
|
|
796 control characters to the remote system to which they connect.
|
|
|
797 On such systems, emacs on the remote system cannot disable flow
|
|
|
798 control on the local system.
|
|
|
799
|
|
|
800 One way to cure this is to disable flow control on the local host
|
|
|
801 (the one running rlogin, not the one running rlogind) using the
|
|
|
802 stty command, before starting the rlogin process. On many systems,
|
|
120
|
803 `stty start u stop u' will do this.
|
|
0
|
804
|
|
|
805 Some versions of tcsh will prevent even this from working. One way
|
|
|
806 around this is to start another shell before starting rlogin, and
|
|
|
807 issue the stty command to disable flow control from that shell.
|
|
|
808
|
|
|
809 If none of these methods work, the best solution is to type
|
|
120
|
810 `M-x enable-flow-control' at the beginning of your emacs session, or
|
|
0
|
811 if you expect the problem to continue, add a line such as the
|
|
|
812 following to your .emacs (on the host running rlogind):
|
|
|
813
|
|
|
814 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")

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

822 is wrong, or it could mean that Emacs has a bug handing the
|
|
|
823 combination of features specified for that terminal.
|
|
0
|
824
|
|
|
825 The first step in tracking this down is to record what characters
|
|
|
826 Emacs is sending to the terminal. Execute the Lisp expression
|
|
120
|
827 (open-termscript "./emacs-script") to make Emacs write all terminal
|
|
|
828 output into the file ~/emacs-script as well; then do what makes the
|
|
|
829 screen update wrong, and look at the file and decode the characters
|
|
|
830 using the manual for the terminal. There are several possibilities:
|
|
0
|
831
|
|
|
832 1) The characters sent are correct, according to the terminal manual.
|
|
|
833
|
|
|
834 In this case, there is no obvious bug in Emacs, and most likely you
|
|
|
835 need more padding, or possibly the terminal manual is wrong.
|
|
|
836
|
|
120
|
837 2) The characters sent are incorrect, due to an obscure aspect of the
|
|
|
838 terminal behavior not described in an obvious way by termcap.
|
|
0
|
839
|
|
120
|
840 This case is hard. It will be necessary to think of a way for Emacs
|
|
|
841 to distinguish between terminals with this kind of behavior and other
|
|
|
842 terminals that behave subtly differently but are classified the same
|
|
|
843 by termcap; or else find an algorithm for Emacs to use that avoids the
|
|
|
844 difference. Such changes must be tested on many kinds of terminals.

857 ** Output from Control-V is slow.
|
|
0
|
858
|
|
|
859 On many bit-map terminals, scrolling operations are fairly slow.
|
|
|
860 Often the termcap entry for the type of terminal in use fails
|
|
|
861 to inform Emacs of this. The two lines at the bottom of the screen
|
|
|
862 before a Control-V command are supposed to appear at the top after
|
|
|
863 the Control-V command. If Emacs thinks scrolling the lines is fast,
|
|
|
864 it will scroll them to the top of the screen.
|
|
|
865
|
|
|
866 If scrolling is slow but Emacs thinks it is fast, the usual reason is
|
|
|
867 that the termcap entry for the terminal you are using does not
|
|
|
868 specify any padding time for the `al' and `dl' strings. Emacs
|
|
|
869 concludes that these operations take only as much time as it takes to
|
|
|
870 send the commands at whatever line speed you are using. You must
|
|
|
871 fix the termcap entry to specify, for the `al' and `dl', as much
|
|
|
872 time as the operations really take.
|
|
|
873
|
|
|
874 Currently Emacs thinks in terms of serial lines which send characters
|
|
|
875 at a fixed rate, so that any operation which takes time for the
|
|
|
876 terminal to execute must also be padded. With bit-map terminals
|
|
|
877 operated across networks, often the network provides some sort of
|
|
|
878 flow control so that padding is never needed no matter how slow
|
|
|
879 an operation is. You must still specify a padding time if you want
|
|
|
880 Emacs to realize that the operation takes a long time. This will
|
|
|
881 cause padding characters to be sent unnecessarily, but they do
|
|
|
882 not really cost much. They will be transmitted while the scrolling
|
|
|
883 is happening and then discarded quickly by the terminal.
|
|
|
884
|
|
|
885 Most bit-map terminals provide commands for inserting or deleting
|
|
|
886 multiple lines at once. Define the `AL' and `DL' strings in the
|
|
|
887 termcap entry to say how to do these things, and you will have
|
|
|
888 fast output without wasted padding characters. These strings should
|
|
|
889 each contain a single %-spec saying how to send the number of lines
|
|
|
890 to be scrolled. These %-specs are like those in the termcap
|
|
|
891 `cm' string.
|
|
|
892
|
|
|
893 You should also define the `IC' and `DC' strings if your terminal
|
|
|
894 has a command to insert or delete multiple characters. These
|
|
|
895 take the number of positions to insert or delete as an argument.
|
|
|
896
|
|
|
897 A `cs' string to set the scrolling region will reduce the amount
|
|
|
898 of motion you see on the screen when part of the screen is scrolled.

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

1042 While making the OS and the compiler able to work on 64b

1043 architectures, SGI designed another mode for using registers

|
1044 and passing parameters between functions, activated on the

1045 compiler by using -64. Since it was much more efficient ar
|
|
|
1046 using registers even for 32b architectures, they designed
|
|
|
1047 a version for 32b called n32. And it _is_ really better.
|
|
|
1048 This mode should always be used when not using gcc (which
|
|
|
1049 can only do o32 afaik).
|
|
|
1050
|
|
|
1051 Too bad xemacs can't do n32 out of the box. So here is what
|
|
|
1052 I had to do to compile it in this mode:
|
|
|
1053
|
|
|
1054 s/irix6-0.h:
|
|
|
1055 - #define LD_SWITCH_SYSTEM -32
|
|
|
1056 + #define LD_SWITCH_SYSTEM -n32 -G 0
|
|
|
1057
|
|
|
1058 m/iris4d.h:
|
|
|
1059 - #define LIBS_MACHINE -lmld
|
|
|
1060 + #define LIBS_MACHINE
|
|
|
1061
|
|
|
1062 - #define C_SWITCH_MACHINE -32
|
|
|
1063 + #define C_SWITCH_MACHINE -n32 -G 0
|
|
|
1064
|
|
|
1065 (the mld lib does not exist in n32 mode)
|
|
|
1066
|
|
|
1067 I also added a --cflags='-n32 -O2 -G 0 -s' to the configuration
|
|
|
1068 line but it seems that these flags are ignored for configure test
|
|
|
1069 and since o32 and n32 libraries are independant I had to revert
|
|
|
1070 to the CFLAGS env var.
|
|
|
1071
|
|
|
1072 Anyway, once done that the compile has gone succesfully, the dump
|
|
|
1073 was OK and I'm writing this in the resulting xemacs-20.2b1 ;-)

1075 ** Slow startup on Linux.
|
|
|
1076
|
|
|
1077 People using systems based on the Linux kernel sometimes report that
|
|
|
1078 startup takes 10 to 15 seconds longer than `usual'.
|
|
|
1079
|
|
|
1080 This is because Emacs looks up the host name when it starts.
|
|
|
1081 Normally, this takes negligible time; the extra delay is due to
|
|
|
1082 improper system configuration. This problem can occur for both
|
|
|
1083 networked and non-networked machines.
|
|
0
|
1084
|
|
124
|
1085 Here is how to fix the configuration. It requires being root.
|
|
|
1086
|
|
|
1087 *** Networked Case
|
|
|
1088
|
|
|
1089 First, make sure the files `/etc/hosts' and `/etc/host.conf' both
|
|
|
1090 exist. The first line in the `/etc/hosts' file should look like this
|
|
|
1091 (replace HOSTNAME with your host name):
|
|
|
1092
|
|
|
1093 127.0.0.1 localhost HOSTNAME
|
|
|
1094
|
|
|
1095 Also make sure that the `/etc/host.conf' files contains the following
|
|
|
1096 lines:
|
|
|
1097
|
|
|
1098 order hosts, bind
|
|
|
1099 multi on
|
|
|
1100
|
|
|
1101 Any changes, permanent and temporary, to the host name should be
|
|
|
1102 indicated in the `/etc/hosts' file, since it acts a limited local
|
|
|
1103 database of addresses and names (e.g., some SLIP connections
|
|
|
1104 dynamically allocate ip addresses).
|
|
|
1105
|
|
|
1106 *** Non-Networked Case
|
|
|
1107
|
|
|
1108 The solution described in the networked case applies here as well.
|
|
|
1109 However, if you never intend to network your machine, you can use a
|
|
|
1110 simpler solution: create an empty `/etc/host.conf' file. The command
|
|
|
1111 `touch /etc/host.conf' suffices to create the file. The `/etc/hosts'
|
|
|
1112 file is not necessary with this approach.
|
|
|
1113
|
|
|
1114 ** On Solaris 2.4, Dired hangs and C-g does not work. Or Emacs hangs
|
|
|
1115 forever waiting for termination of a subprocess that is a zombie.
|
|
|
1116
|
|
|
1117 casper@fwi.uva.nl says the problem is in X11R6. Rebuild libX11.so
|
|
|
1118 after changing the file xc/config/cf/sunLib.tmpl. Change the lines
|
|
|
1119
|
|
|
1120 #if ThreadedX
|
|
|
1121 #define SharedX11Reqs -lthread
|
|
|
1122 #endif
|
|
|
1123
|
|
|
1124 to:
|
|
|
1125
|
|
|
1126 #if OSMinorVersion < 4
|
|
|
1127 #if ThreadedX
|
|
|
1128 #define SharedX11Reqs -lthread
|
|
|
1129 #endif
|
|
|
1130 #endif
|
|
|
1131
|
|
|
1132 Be sure also to edit x/config/cf/sun.cf so that OSMinorVersion is 4
|
|
|
1133 (as it should be for Solaris 2.4). The file has three definitions for
|
|
|
1134 OSMinorVersion: the first is for x86, the second for SPARC under
|
|
|
1135 Solaris, and the third for SunOS 4. Make sure to update the
|
|
|
1136 definition for your type of machine and system.
|
|
|
1137
|
|
|
1138 Then do `make Everything' in the top directory of X11R6, to rebuild
|
|
|
1139 the makefiles and rebuild X. The X built this way work only on
|
|
|
1140 Solaris 2.4, not on 2.3.
|
|
|
1141
|
|
|
1142 For multithreaded X to work it necessary to install patch
|
|
|
1143 101925-02 to fix problems in header files [2.4]. You need
|
|
|
1144 to reinstall gcc or re-run just-fixinc after installing that
|
|
|
1145 patch.

|
1146
|
|
124
|
1147 However, Frank Rust <frust@iti.cs.tu-bs.de> used a simpler solution:
|
|
|
1148 he changed
|
|
|
1149 #define ThreadedX YES
|
|
|
1150 to
|
|
|
1151 #define ThreadedX NO
|
|
|
1152 in sun.cf and did `make World' to rebuild X11R6. Removing all
|
|
|
1153 `-DXTHREAD*' flags and `-lthread' entries from lib/X11/Makefile and
|
|
|
1154 typing 'make install' in that directory also seemed to work.
|
|
|

|
1158
|
|
124
|
1159 This has been traced to communicating with your machine via kermit,
|
|
|
1160 with C-\ as the kermit escape character. One solution is to use
|
|
|
1161 another escape character in kermit. One user did
|
|
|
1162
|
|
|
1163 set escape-character 17
|
|
|
1164
|
|
|
1165 in his .kermrc file, to make C-q the kermit escape character.

1167 ** The Motif version of Emacs paints the screen a solid color.

|
|

1172
|
|
|
1173 That the resource has this effect indicates a bug in something, but we
|
|
|
1174 do not yet know what. If it is an Emacs bug, we hope someone can
|
|
|
1175 explain what the bug is so we can fix it. In the mean time, removing
|
|
|
1176 the resource prevents the problem.

1178 ** Regular expressions matching bugs on SCO systems.

1187

1188 This happens to people who use tcsh, because it is trying to be too
|
|
|
1189 smart. It sees that the Shell uses terminal type `unknown' and turns
|
|
|
1190 on the flag to output ^M at the end of each line. You can fix the
|
|
|
1191 problem by adding this to your .cshrc file:
|
|
|
1192
|
|
|
1193 if ($?EMACS) then
|
|
|
1194 if ($EMACS == "t") then

|
|
1196 stty -icrnl -onlcr -echo susp ^Z

1200 ** An error message such as `X protocol error: BadMatch (invalid

1203 This comes from having an invalid X resource, such as
|
|
|
1204 emacs*Cursor: black
|
|
|
1205 (which is invalid because it specifies a color name for something
|
|
|
1206 that isn't a color.)
|
|
|
1207
|
|
|
1208 The fix is to correct your X resources.

1210 ** Mail is lost when sent to local aliases.
|

0
|
1211
|
|
124
|
1212 Many emacs mail user agents (VM and rmail, for instance) use the
|
|
|
1213 sendmail.el library. This library can arrange for mail to be
|
|
|
1214 delivered by passing messages to the /usr/lib/sendmail (usually)
|
|
|
1215 program . In doing so, it passes the '-t' flag to sendmail, which
|
|
|
1216 means that the name of the recipient of the message is not on the
|
|
|
1217 command line and, therefore, that sendmail must parse the message to
|
|
|
1218 obtain the destination address.
|
|
|
1219
|
|
|
1220 There is a bug in the SunOS4.1.1 and SunOS4.1.3 versions of sendmail.
|
|
|
1221 In short, when given the -t flag, the SunOS sendmail won't recognize
|
|
|
1222 non-local (i.e. NIS) aliases. It has been reported that the Solaris
|
|
|
1223 2.x versions of sendmail do not have this bug. For those using SunOS
|
|
|
1224 4.1, the best fix is to install sendmail V8 or IDA sendmail (which
|
|
|
1225 have other advantages over the regular sendmail as well). At the time
|
|
|
1226 of this writing, these official versions are available:
|
|
|
1227
|
|
|
1228 Sendmail V8 on ftp.cs.berkeley.edu in /ucb/sendmail:
|
|
|
1229 sendmail.8.6.9.base.tar.Z (the base system source & documentation)
|

1254

1255 Some versions of SVR4 have a serious bug in the implementation of the

|
|
|
1257 the first time, and then crash when run a second time.
|
|
|
1258
|
|
|
1259 Contact your vendor and ask for the mmap bug fix; in the mean time,
|
|
|
1260 you may be able to work around the problem by adding a line to your
|
|
|
1261 operating system description file (whose name is reported by the
|
|
|
1262 configure script) that reads:
|

1263 #define SYSTEM_MALLOC

|
1270 If you have tried to bind an Alt-modified key as a command, and it
|
|
|
1271 does not work to type the command, the first thing you should check is
|
|
|
1272 whether the key is getting through to Emacs. To do this, type C-h c
|
|
|
1273 followed by the Alt-modified key. C-h c should say what kind of event
|
|
|
1274 it read. If it says it read an Alt-modified key, then make sure you
|
|
|
1275 have made the key binding correctly.
|
|
|
1276
|
|
|
1277 If C-h c reports an event that doesn't have the Alt modifier, it may
|
|
|
1278 be because your X server has no key for the Alt modifier. The X
|
|
|
1279 server that comes from MIT does not set up the Alt modifier by
|
|
|
1280 default.
|
|
|
1281
|
|
|
1282 If your keyboard has keys named Alt, you can enable them as follows:
|
|
0
|
1283
|
|
124
|
1284 xmodmap -e 'add mod2 = Alt_L'
|
|
|
1285 xmodmap -e 'add mod2 = Alt_R'
|
|
|
1286
|
|
|
1287 If the keyboard has just one key named Alt, then only one of those
|
|
|
1288 commands is needed. The modifier `mod2' is a reasonable choice if you
|
|
|
1289 are using an unmodified MIT version of X. Otherwise, choose any
|
|
|
1290 modifier bit not otherwise used.
|
|
0
|
1291
|
|
124
|
1292 If your keyboard does not have keys named Alt, you can use some other
|
|
|
1293 keys. Use the keysym command in xmodmap to turn a function key (or
|
|
|
1294 some other 'spare' key) into Alt_L or into Alt_R, and then use the
|
|
|
1295 commands show above to make them modifier keys.
|
|
|
1296
|
|
|
1297 Note that if you have Alt keys but no Meta keys, Emacs translates Alt
|
|
|
1298 into Meta. This is because of the great importance of Meta in Emacs.

|
1302 On HP/UX, you can get that error when the Emacs executable is on an NFS
|
|
|
1303 file system. HP/UX responds this way if it tries to swap in a page and
|
|
|
1304 does not get a response from the server within a timeout whose default
|
|
|
1305 value is just ten seconds.
|
|
|
1306
|
|

1307 If this happens to you, extend the timeout period.

1309 ** `expand-file-name' fails to work on any but the machine you dumped Emacs on.
|

1310
|
|
|
1311 On Ultrix, if you use any of the functions which look up information
|
|
|
1312 in the passwd database before dumping Emacs (say, by using
|
|
|
1313 expand-file-name in site-init.el), then those functions will not work
|
|
|
1314 in the dumped Emacs on any host but the one Emacs was dumped on.
|
|
|
1315
|
|
|
1316 The solution? Don't use expand-file-name in site-init.el, or in
|
|
|
1317 anything it loads. Yuck - some solution.

1319 I'm not sure why this happens; if you can find out exactly what is

1320 going on, and perhaps find a fix or a workaround, please let us know.
|
|
|
1321 Perhaps the YP functions cache some information, the cache is included
|
|
|
1322 in the dumped Emacs, and is then inaccurate on any other host.

1329 This typically happens on Suns and other systems that use shared
|
|
|
1330 libraries. The cause is that the site has installed a version of the
|
|
|
1331 shared library which uses a name server--but has not installed a
|
|
|
1332 similar version of the unshared library which Emacs uses.
|
|
0
|
1333
|
|
124
|
1334 The result is that most programs, using the shared library, work with
|
|
|
1335 the nameserver, but Emacs does not.
|
|
|
1336
|
|
|
1337 The fix is to install an unshared library that corresponds to what you
|
|
|
1338 installed in the shared library, and then relink Emacs.

1340 On SunOS 4.1, simply define HAVE_RES_INIT.
|
|
|
1341
|
|
|
1342 If you have already installed the name resolver in the file libresolv.a,
|
|
|
1343 then you need to compile Emacs to use that library. The easiest way to
|
|
|
1344 do this is to add to config.h a definition of LIBS_SYSTEM, LIBS_MACHINE
|
|
|
1345 or LIB_STANDARD which uses -lresolv. Watch out! If you redefine a macro
|
|
|
1346 that is already in use in your configuration to supply some other libraries,
|
|
|
1347 be careful not to lose the others.
|
|
|
1348
|
|
|
1349 Thus, you could start by adding this to config.h:
|
|
|
1350
|
|
|
1351 #define LIBS_SYSTEM -lresolv
|
|
|
1352
|
|
|
1353 Then if this gives you an error for redefining a macro, and you see that
|
|
|
1354 the s- file defines LIBS_SYSTEM as -lfoo -lbar, you could change config.h
|
|
|
1355 again to say this:
|
|
|
1356
|
|
|
1357 #define LIBS_SYSTEM -lresolv -lfoo -lbar
|
|
|
1358

1359 ** Bus errors on startup when compiled with Sun's "acc" (in the routine
|
|
|
1360 make_string_internal() called from initialize_environment_alist())
|
|
|
1361
|
|
|
1362 The Sun ANSI compiler doesn't place uninitialized static variables in BSS
|
|
|
1363 space like other compilers do. This breaks emacs. If you want to use acc,
|
|
|
1364 you need to make the file "lastfile.o" be the *first* file in the link
|
|
|
1365 command. Better yet, use Lucid C or GCC.

|
|
|
1374 christos@theory.tn.cornell.edu says:
|
|
|
1375
|
|
|
1376 The problem is that in your .cshrc you have something that tries to
|
|
|
1377 execute `tty`. If you are not running the shell on a real tty then
|
|
|
1378 tty will print "not a tty". Csh expects one word in some places,
|
|
|
1379 but tty is giving it back 3.
|
|
|
1380
|
|
|
1381 The solution is to add a pair of quotes around `tty` to make it a single
|
|
|
1382 word:
|
|
0
|
1383
|
|
124
|
1384 if (`tty` == "/dev/console")
|
|
|
1385
|
|
|
1386 should be changed to:
|
|
|
1387
|
|
|
1388 if ("`tty`" == "/dev/console")
|
|
|
1389
|
|
|
1390 Even better, move things that set up terminal sections out of .cshrc
|
|
|
1391 and into .login.

1396 On SunOS systems, this problem has been seen to be a result of an incomplete

1398 into the compilation. In particular this affected virtually all ioctl() calls.

1402 It has been claimed that this is caused by a bug in certain very old (1990?)

1404 or with other window managers.

88

1407
|
|
124
|
1408 OLWM grabs the help key, and retransmits it to the appropriate client using
|
|
|
1409 XSendEvent. Allowing emacs to react to synthetic events is a security hole,
|
|
|
1410 so this is turned off by default. You can enable it by setting the variable
|
|
|
1411 x-allow-sendevents to t. You can also cause fix this by telling OLWM to not
|
|
|
1412 grab the help key, with the null binding "OpenWindows.KeyboardCommand.Help:".

1415 terminal type.
|
|
88
|
1416
|
|
124
|
1417 The cause of this is a shell startup file that sets the TERMCAP
|
|
|
1418 environment variable. The terminal emulator uses that variable to
|
|
|
1419 provide the information on the special terminal type that Emacs
|
|
|
1420 emulates.
|
|
88
|
1421
|
|
124
|
1422 Rewrite your shell startup file so that it does not change TERMCAP
|
|
|
1423 in such a case. You could use the following conditional which sets
|
|
|
1424 it only if it is undefined.
|
|
|
1425
|
|
|
1426 if ( ! ${?TERMCAP} ) setenv TERMCAP ~/my-termcap-file
|
|
|
1427
|
|
|
1428 Or you could set TERMCAP only when you set TERM--which should not
|
|
|
1429 happen in a non-login shell.

1436
|
|
124
|
1437 There are a few incompatible changes in XEmacs, and these are the
|
|
|
1438 symptoms. Some of the emacs-lisp code you are running needs to be
|
|
|
1439 updated to be compatible with XEmacs.
|
|
|
1440
|
|
|
1441 The code should not treat keymaps as arrays (use `define-key', etc.),
|
|
|
1442 should not use obsolete variables like `unread-command-char' (use
|
|
|
1443 `unread-command-event'). Many (most) of the new ways of doing things
|
|
|
1444 are compatible in GNU Emacs and XEmacs.
|
|
88
|
1445
|
|
124
|
1446 Modern Emacs packages (Gnus, VM, etc) are written to support GNU Emacs
|
|
|
1447 and XEmacs. We have provided modified versions of several popular
|
|
|
1448 emacs packages (dired, etc) which are compatible with this version of
|
|
|
1449 emacs. Check to make sure you have not set your load-path so that
|
|
|
1450 your private copies of these packages are being found before the
|
|
|
1451 versions in the lisp directory.
|
|
|
1452
|
|
|
1453 Make sure that your load-path and your $EMACSLOADPATH environment
|
|
|
1454 variable are not pointing at an Emacs18 lisp directory. This will
|
|
|
1455 cripple emacs.

|
|
1462 face-foreground, face-background, face-background-pixmap, and face-underline-p.
