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:
|

11 - Problems with building XEmacs
|
|
|
12 - Problems with running XEmacs
|
|
|
13 - Compatibility problems
|

14 - Mule issues

|
16 Use `C-c C-f' to move to the next equal level of outline, and
|
|
223
|
17 `C-c C-b' to move to previous equal level. `C-h m' will give more
|
|
|
18 info about the Outline mode.
|
|
120
|
19
|
|
197
|
20 Also, Try finding the things you need using one of the search commands
|
|
|
21 XEmacs provides (e.g. `C-s').
|
|
|
22
|
|
524
|
23 General advice:
|
|
957
|
24
|
|
524
|
25 WATCH OUT for your init file! (~/.xemacs/init.el or ~/.emacs) If
|
|
|
26 you observe strange problems, invoke XEmacs with the `-vanilla'
|
|
|
27 option and see if you can repeat the problem.
|
|
197
|
28
|
|
957
|
29 Note that most of the problems described here manifest at RUN
|
|
|
30 time, even those described as BUILD problems. It is quite unusual
|
|
|
31 for a released XEmacs to fail to build. So a "build problem"
|
|
|
32 requires you to tweak the build environment, then rebuild XEmacs.
|
|
|
33 A "runtime problem" is one that can be fixed by proper
|
|
|
34 configuration of the existing build. Compatibility problems and
|
|
|
35 Mule issues are generally runtime problems, but are treated
|
|
|
36 separately for convenience.

39 * Problems with building XEmacs

|
42 ** General
|
|
915
|
43 Much general information is in INSTALL. If it's covered in
|
|
|
44 INSTALL, we don't repeat it here.
|
|
|
45
|
|
|
46 *** How does I configure to get the buffer tabs/progress bars?
|
|
|
47
|
|
|
48 These features depend on support for "native widgets". Use the
|
|
|
49 --with-widgets option to configure. Configuration of widgets is
|
|
|
50 automatic for "modern" toolkits (MS Windows, GTK, and Motif), but if
|
|
|
51 you are using Xt and the Athena widgets, you will probably want to
|
|
|
52 specify a "3d" widget set. See configure --usage, and don't forget to
|
|
|
53 install the corresponding development libraries.
|
|
|
54
|
|
|
55 *** I know I have libfoo installed, but configure doesn't find it.
|
|
|
56
|
|
|
57 Typical of Linux systems with package managers. To link with a shared
|
|
|
58 library, you only need the shared library. To compile objects that
|
|
|
59 link with it, you need the headers---and distros don't provide them with
|
|
|
60 the libraries. You need the additional "development" package, too.
|
|
|
61
|
|
394
|
62 *** Don't use -O2 with gcc 2.8.1 and egcs 1.0 under SPARC architectures
|
|
|
63 without also using `-fno-schedule-insns'.
|
|
|
64
|
|
|
65 gcc will generate incorrect code otherwise, typically resulting in
|
|
|
66 crashes in the function skip-syntax-backward.
|
|
|
67
|
|
382
|
68 *** egcs-1.1
|
|
|
69
|
|
|
70 There have been reports of egcs-1.1 not compiling XEmacs correctly on
|
|
|
71 Alpha Linux. There have also been reports that egcs-1.0.3a is O.K.
|
|
|
72
|
|
432
|
73 *** Don't use -O2 or -O3 with Cygwin 1.0, CodeFusion-99070 or gcc 2.7.2 on x86
|
|
|
74 without also using `-fno-strength-reduce'.
|
|
124
|
75
|
|
|
76 gcc will generate incorrect code otherwise. This bug is present in at
|
|
|
77 least 2.6.x and 2.7.[0-2]. This bug has been fixed in GCC 2.7.2.1 and
|
|
263
|
78 later. This bug is O/S independent, but is limited to x86 architectures.
|
|
|
79
|
|
|
80 This problem is known to be fixed in egcs (or pgcc) 1.0 or later.
|
|
229
|
81
|
|
432
|
82 Unfortunately, later releases of Cygnus-released compilers (not the
|
|
|
83 Net-released ones) have a bug with the same `problem signature'.
|
|
|
84
|
|
|
85 If you're lucky, you'll get an error while compiling that looks like:
|
|
|
86
|
|
|
87 event-stream.c:3189: internal error--unrecognizable insn:
|
|
|
88 (insn 256 14 15 (set (reg/v:SI 24)
|
|
|
89 (minus:SI (reg/v:SI 25)
|
|
|
90 (const_int 2))) -1 (insn_list 11 (nil))
|
|
|
91 (nil))
|
|
|
92 0 0 [main]
|
|
|
93
|
|
|
94 If you're unlucky, your code will simply execute incorrectly.
|
|
|
95
|
|
|
96 *** Don't use gcc-2.95.2 with -mcpu=ultrasparc on Solaris 2.6.
|
|
|
97
|
|
|
98 gcc will assume a 64-bit operating system, even though you've
|
|
|
99 merely told it to assume a 64-bit instruction set.
|
|
|
100
|
|
373
|
101 *** Don't use -O2 with gcc 2.7.2 under Intel architectures without also
|
|
229
|
102 using `-fno-caller-saves'.
|
|
|
103
|
|
263
|
104 gcc will generate incorrect code otherwise. This bug is still
|
|
|
105 present in gcc 2.7.2.3. There have been no reports to indicate the
|
|
|
106 bug is present in egcs 1.0 (or pgcc 1.0) or later. This bug is O/S
|
|
|
107 independent, but limited to x86 architectures.
|
|
|
108
|
|
|
109 This problem is known to be fixed in egcs (or pgcc) 1.0 or later.
|
|
124
|
110
|
|
373
|
111 *** When using gcc, you get the error message "undefined symbol __fixunsdfsi".
|
|
|
112 When using gcc, you get the error message "undefined symbol __main".
|
|
|
113
|
|
|
114 This means that you need to link with the gcc library. It may be called
|
|
|
115 "gcc-gnulib" or "libgcc.a"; figure out where it is, and define LIB_GCC in
|
|
|
116 config.h to point to it.
|
|
|
117
|
|
|
118 It may also work to use the GCC version of `ld' instead of the standard one.
|
|
|
119
|
|
|
120 *** Excessive optimization with pgcc can break XEmacs
|
|
124
|
121
|
|
|
122 It has been reported on some systems that compiling with -O6 can lead
|
|
|
123 to XEmacs failures. The workaround is to use a lower optimization
|
|
|
124 level. -O2 and -O4 have been tested extensively.
|
|
|
125
|
|
229
|
126 All of this depends heavily on the version of pgcc and the version
|
|
|
127 of libc. Snapshots near the release of pgcc-1.0 have been tested
|
|
|
128 extensively and no sign of breakage has been seen on systems using
|
|
|
129 glibc-2.
|
|
|
130
|
|
373
|
131 *** src/Makefile and lib-src/Makefile are truncated--most of the file missing.
|
|
229
|
132
|
|
373
|
133 This can happen if configure uses GNU sed version 2.03. That version
|
|
|
134 had a bug. GNU sed version 2.05 works properly.
|
|
124
|
135
|
|
373
|
136 *** When compiling with X11, you get "undefined symbol _XtStrings".
|
|
124
|
137
|
|
373
|
138 This means that you are trying to link emacs against the X11r4 version of
|
|
|
139 libXt.a, but you have compiled either Emacs or the code in the lwlib
|
|
|
140 subdirectory with the X11r5 header files. That doesn't work.
|
|
124
|
141
|
|
373
|
142 Remember, you can't compile lwlib for r4 and emacs for r5, or vice versa.
|
|
|
143 They must be in sync.
|
|
124
|
144
|
|
373
|
145 *** test-distrib says that the distribution has been clobbered
|
|
197
|
146 or, temacs prints "Command key out of range 0-127"
|
|
|
147 or, temacs runs and dumps xemacs, but xemacs totally fails to work.
|
|
|
148 or, temacs gets errors dumping xemacs
|
|
|
149
|
|
|
150 This can be because the .elc files have been garbled. Do not be
|
|
|
151 fooled by the fact that most of a .elc file is text: these are binary
|
|
|
152 files and can contain all 256 byte values.
|
|
|
153
|
|
|
154 In particular `shar' cannot be used for transmitting GNU Emacs. It
|
|
|
155 typically truncates "lines". (this does not apply to GNU shar, which
|
|
|
156 uses uuencode to encode binary files.)
|
|
|
157
|
|
|
158 If you have a copy of Emacs that has been damaged in its nonprinting
|
|
|
159 characters, you can fix them by running:
|
|
|
160
|
|
|
161 make all-elc
|
|
|
162
|
|
|
163 This will rebuild all the needed .elc files.
|
|
|
164
|
|
373
|
165 *** `compress' and `uncompress' not found and XFree86
|
|
|
166
|
|
|
167 XFree86 installs a very old version of libz.a by default ahead of where
|
|
|
168 more modern version of libz might be installed. This will cause problems
|
|
|
169 when attempting to link against libMagick. The fix is to remove the old
|
|
|
170 libz.a in the X11 binary directory.
|
|
|
171
|
|
|
172
|
|
|
173 ** AIX
|
|
1009
|
174 *** IBM compiler fails: "The character # is not a valid C source character."
|
|
|
175
|
|
|
176 Most recently observed in 21.5.9, due to USE_KKCC ifdefs (they just
|
|
|
177 happen to tickle the implementation).
|
|
|
178
|
|
|
179 Valdis Kletnieks says:
|
|
|
180
|
|
|
181 The problem is that IBM defines a *MACRO* called 'memcpy', and we
|
|
|
182 have stuck a #ifdef/#endif inside the macro call. As a workaround,
|
|
|
183 try adding '-U__STR__' to your CFLAGS - this will cause string.h to
|
|
|
184 not do a #define for strcpy() to __strcpy() - it uses this for
|
|
|
185 automatic inlining support.
|
|
|
186
|
|
|
187 (For the record, the same issue affects a number of other functions
|
|
|
188 defined in string.h - basically anything the compiler knows how to
|
|
|
189 inline.)
|
|
|
190
|
|
373
|
191 *** On AIX 4.3, you must specify --with-dialogs=athena with configure
|
|
|
192
|
|
442
|
193 *** The libXt shipped with AIX 4.3 up to 4.3.2 is broken. This causes
|
|
|
194 xemacs -nw to fail in various ways. The official APAR is this:
|
|
|
195
|
|
|
196 APAR NUMBER: <IX89470> RESOLVED AS: PROGRAM ERROR
|
|
|
197
|
|
|
198 ABSTRACT:
|
|
|
199 <IX89470>: LIBXT.A INCORRECT HANDLING OF EXCEPTIONS IN XTAPPADDINPUT
|
|
|
200
|
|
|
201 The solution is to install X11.base.lib at version >=4.3.2.5.
|
|
392
|
202
|
|
373
|
203 *** On AIX, you get this compiler error message:
|
|
|
204
|
|
|
205 Processing include file ./XMenuInt.h
|
|
|
206 1501-106: (S) Include file X11/Xlib.h not found.
|
|
|
207
|
|
|
208 This means your system was installed with only the X11 runtime i.d
|
|
|
209 libraries. You have to find your sipo (bootable tape) and install
|
|
|
210 X11Dev... with smit.
|
|
|
211
|
|
|
212 *** On AIX 4.1.2, linker error messages such as
|
|
|
213 ld: 0711-212 SEVERE ERROR: Symbol .__quous, found in the global symbol table
|
|
|
214 of archive /usr/lib/libIM.a, was not defined in archive member shr.o.
|
|
|
215
|
|
|
216 This is a problem in libIM.a. You can work around it by executing
|
|
|
217 these shell commands in the src subdirectory of the directory where
|
|
|
218 you build Emacs:
|
|
|
219
|
|
|
220 cp /usr/lib/libIM.a .
|
|
|
221 chmod 664 libIM.a
|
|
|
222 ranlib libIM.a
|
|
|
223
|
|
|
224 Then change -lIM to ./libIM.a in the command to link temacs (in
|
|
|
225 Makefile).
|
|
|
226
|
|
|

263 *** Dumping error when using GNU binutils / GNU ld on a Sun.
|

265 Errors similar to the following:

|
|
266
|
|
|
267 Dumping under the name xemacs unexec():
|
|
|
268 dldump(/space/rpluim/xemacs-obj/src/xemacs): ld.so.1: ./temacs:

|
|
|
270 1879048176
|
|
|
271
|
|
|
272 are caused by using GNU ld. There are several workarounds available:
|
|
|
273
|
|
|
274 In XEmacs 21.2 or later, configure using the new portable dumper
|
|
|
275 (--pdump).
|
|
|
276
|
|
|
277 Alternatively, you can link using the Sun version of ld, which is
|
|
|
278 normally held in /usr/ccs/bin. This can be done by one of:
|
|
|
279
|
|
|
280 - building gcc with these configure flags:
|
|
|
281 configure --with-ld=/usr/ccs/bin/ld --with-as=/usr/ccs/bin/as
|
|
|
282
|
|
|
283 - adding -B/usr/ccs/bin/ to CFLAGS used to configure XEmacs
|
|
|
284 (Note: The trailing '/' there is significant.)
|
|
|
285
|
|
|
286 - uninstalling GNU ld.

287
|
|
|
288 The Solaris2 FAQ claims:
|
|
|
289
|
|
|
290 When you install gcc, don't make the mistake of installing
|
|
|
291 GNU binutils or GNU libc, they are not as capable as their
|
|
|
292 counterparts you get with Solaris 2.x.

|
294 *** Link failure when using acc on a Sun.
|
|
|
295
|
|
|
296 To use acc, you need additional options just before the libraries, such as
|
|
|
297
|
|
|
298 /usr/lang/SC2.0.1/values-Xt.o -L/usr/lang/SC2.0.1/cg87 -L/usr/lang/SC2.0.1
|
|
|
299
|
|
|
300 and you need to add -lansi just before -lc.
|
|
|
301
|
|
|
302 The precise file names depend on the compiler version, so we
|
|
|
303 cannot easily arrange to supply them.

305 *** Problems finding X11 libraries on Solaris with Openwindows
|
|
|
306
|

307 Some users have reported problems in this area. The reported solution

309 it to `/usr/openwin'.

326 The SparcWorks C compiler may have difficulty building those modules

331

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

|
|
344 *** On Sunos 4, you get the error ld: Undefined symbol __lib_version.
|
|
|
345
|
|
|
346 This is the result of using cc or gcc with the shared library meant
|

347 for acc (the Sunpro compiler). Check your LD_LIBRARY_PATH and delete
|
|

348 /usr/lang/SC2.0.1 or some similar directory.

352 If you get the undefined symbols _atowc _wcslen, _iswprint, _iswspace,
|
|
|
353 _iswcntrl, _wcscpy, and _wcsncpy, then you need to add -lXwchar after

369 Apparently the version of libXmu.so.a that Sun ships is hosed: it's missing
|
|
454
|
370 some stuff that is in libXmu.a (the static version). Sun has a patch for
|
|
373
|
371 this, but a workaround is to use the static version of libXmu, by changing
|
|
|
372 the link command from "-lXmu" to "-Bstatic -lXmu -Bdynamic". If you have
|
|
|
373 OpenWindows 3.0, ask Sun for these patches:

374 100512-02 4.1.x OpenWindows 3.0 libXt Jumbo patch

416 There are a couple of problems [with use of -rpath with Irix ld], though:
|
|
|
417
|
|
|
418 1. The ld in IRIX 5.3 ignores all but the last -rpath
|
|
|
419 spec, so the patched configure spits out a warning
|
|
|
420 if --x-libraries or --site-runtime-libraries are
|
|
454
|
421 specified under irix 5.x, and it only adds -rpath
|
|
124
|
422 entries for the --site-runtime-libraries. This bug was
|
|
|
423 fixed sometime between 5.3 and 6.2.
|
|
|
424
|
|
|
425 2. IRIX gcc 2.7.2 doesn't accept -rpath directly, so
|
|
|
426 it would have to be prefixed by -Xlinker or "-Wl,".
|
|
|
427 This would be fine, except that configure compiles with
|
|
|
428 ${CC-cc} $CFLAGS $LDFLAGS ...
|
|
|
429 rather than quoting $LDFLAGS with prefix-args, like
|
|
|
430 src/Makefile does. So if you specify --x-libraries
|
|
|
431 or --site-runtime-libraries, you must use --use-gcc=no,

|
|
124
|
562
|
|
454
|
563 Unlike XEmacs 19.13, building with the native cc on SCO OpenServer 5
|
|
124
|
564 now produces a functional binary. I will typically build this
|
|
|
565 configuration for COFF with:
|
|
|
566
|
|
197
|
567 /path_to_xemacs_source/configure --with-gcc=no \
|
|
124
|
568 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
569 --with-xpm --with-xface --with-sound=nas
|
|
|
570
|
|
454
|
571 This version now supports ELF builds. I highly recommend this to
|
|
|
572 reduce the in-core footprint of XEmacs. This is now how I compile
|
|
124
|
573 all my test releases. Build it like this:
|
|
|
574
|
|
|
575 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
|
576 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
577 --with-xpm --with-xface --with-sound=nas --dynamic
|
|
|
578
|
|
454
|
579 The compiler known as icc [ supplied with the OpenServer 5 Development
|
|
124
|
580 System ] generates a working binary, but it takes forever to generate
|
|
|
581 XEmacs. ICC also whines more about the code than /bin/cc does. I do
|
|
|
582 believe all its whining is legitimate, however. Note that you do
|
|
|
583 have to 'cd src ; make LD=icc' to avoid linker errors.
|
|
|
584
|
|
|
585 The way I handle the build procedure is:
|
|
|
586
|
|
|
587 /path_to_XEmacs_source/configure --with-gcc=no \
|
|
|
588 --site-includes=/usr/local/include --site-libraries=/usr/local/lib \
|
|
|
589 --with-xpm --with-xface --with-sound=nas --dynamic --compiler="icc"
|
|
|
590
|
|
454
|
591 NOTE I have the xpm, xface, and audio libraries and includes in
|
|
124
|
592 /usr/local/lib, /usr/local/include. If you don't have these,
|
|
|
593 don't include the "--with-*" arguments in any of my examples.
|
|
|
594
|
|
454
|
595 In previous versions of XEmacs, you had to override the defaults while
|
|
124
|
596 compiling font-lock.o and extents.o when building with icc. This seems
|
|
|
597 to no longer be true, but I'm including this old information in case it
|
|
|
598 resurfaces. The process I used was:
|
|
|
599
|
|
454
|
600 make -k
|
|
|
601 [ procure pizza, beer, repeat ]
|
|
124
|
602 cd src
|
|
|
603 make CC="icc -W0,-mP1COPT_max_tree_size=3000" font-lock.o extents.o
|
|
|
604 make LD=icc
|
|

605
|
|
454
|
606 If you want sound support, get the tls566 supplement from
|
|
|
607 ftp.sco.com:/TLS or any of its mirrors. It works just groovy

614 In earlier releases, gnuserv/gnuclient/gnudoit would open a frame
|
|
124
|
615 just fine, but the client would lock up and the server would
|
|
454
|
616 terminate when you used C-x # to close the frame. This is now
|
|
124
|
617 fixed in XEmacs.

620 The comments at the top of emacskeys.sco describe its function, and
|
|
|
621 the emacstrs.sco is a suitable candidate for /usr/lib/keyboard/strings
|
|
|
622 to take advantage of the keyboard map in emacskeys.sco.

|
|
|
631 The script etc/check_cygwin_setup.sh will attempt to detect whether
|
|
524
|
632 you have a suitable environment for building. This script may not work
|
|
392

633 correctly if you are using ash instead of bash (see below).

|

392
|
637
|
|
524
|
638 This may be because you are using the default cygwin shell. The
|
|
|
639 default cygwin shell (/bin/sh.exe) is ash which appears to work in
|
|
|
640 most circumstances but has some weird failure modes. You need to
|

641 replace the symlink with bash.exe.

646 Your partition holding the source files is mounted binary. It needs
|
|
|
647 to be mounted text. (This will not screw up any binary files because
|
|
|
648 the Cygwin utilities specify explicitly whether they want binary or
|
|
|
649 text mode when working with source vs. binary files, which overrides
|
|
|
650 the mount type.) To fix this, you just need to run the appropriate
|
|
|
651 mount command once -- afterwards, the settings are remembered in the
|
|
|
652 registry.

677 * Problems with running XEmacs
|
|
|
678 ==============================
|
|
|
679 ** General
|
|
1042
|
680 *** At startup I get a warning on stderr about missing charsets:
|
|
|
681
|
|
|
682 Warning: Missing charsets in String to FontSet conversion
|
|
|
683
|
|
|
684 You need to specify appropriate charsets for your locale (usually the
|
|
1056
|
685 value of the LANG environment variable) in .Xresources. See
|
|
|
686 etc/Emacs.ad for the relevant resources (mostly menubar fonts and
|
|
|
687 fontsets). Do not edit this file, it's purely informative.
|
|
|
688
|
|
|
689 If you have no satisfactory fonts for iso-8859-1, XEmacs will crash.
|
|
|
690
|
|
|
691 It looks like XFree86 4.x (the usual server on Linux and *BSD) has
|
|
|
692 some braindamage where .UTF-8 locales will always generate this
|
|
|
693 message, because the XFree86 (font)server doesn't know that UTF-8 will
|
|
|
694 use the ISO10646-1 font registry (or a Cmap or something).
|
|
|
695
|
|
|
696 If you are not using a .UTF-8 locale and see this warning for a
|
|
|
697 character set not listed in the default in Emacs.ad, please let
|
|
1042
|
698 xemacs-beta@xemacs.org know about it, so we can add fonts to the
|
|
|
699 appropriate fontsets and stifle this warning. (Unfortunately it's
|
|
|
700 buried in Xlib, so we can't easily get rid of it otherwise.)

710 Thanks to giacomo boffi <giacomo.boffi@polimi.it> on comp.emacs.xemacs:
|
|
|
711
|
|
|
712 tell your ftp client to not attempt AUTH authentication (or do not
|
|
|
713 use FTP servers that don't understand AUTH)
|
|
|
714
|
|
|
715 and notes that you need to add an element (often "-u") to
|
|
|
716 `efs-ftp-program-args'. Use M-x customize-variable, and verify the
|
|
|
717 needed flag with `man ftp' or other local documentation.

719 *** gnuserv is running, some clients can connect, but others cannot.
|
|
|
720
|
|
|
721 The code in gnuslib.c respects the value of TMPDIR. If the server and
|
|
|
722 the client have different values in their environment, you lose.
|
|
|
723 One program known to set TMPDIR and manifest this problem is exmh.
|
|
|
724 You can defeat the use of TMPDIR by unsetting USE_TMPDIR at the top of
|
|
|
725 gnuserv.h at build time.
|

|
727 *** C-z just refreshes the screen instead of suspending Emacs.
|
|
124
|
728
|
|
|
729 You are probably using a shell that doesn't support job control, even
|
|
197
|
730 though the system itself is capable of it. Try using a different
|
|
|
731 shell.
|
|
124
|
732
|
|
373
|
733 *** You type Control-H (Backspace) expecting to delete characters.
|
|
124
|
734
|
|
|
735 Emacs has traditionally used Control-H for help; unfortunately this
|
|
424
|
736 interferes with its use as Backspace on TTY's. As of XEmacs 21,
|
|
|
737 XEmacs looks at the "erase" setting of TTY structures and maps C-h to
|
|
|
738 backspace when erase is set to C-h. This is sort of a special hack,
|
|
|
739 but it makes it possible for you to use the standard:
|
|
|
740
|
|
|
741 stty erase ^H
|
|
355
|
742
|
|
424
|
743 to get your backspace key to erase characters. The erase setting is
|
|
|
744 recorded in the Lisp variable `tty-erase-char', which you can use to
|
|
|
745 tune the settings in your .emacs.
|
|
124
|
746
|
|
424
|
747 A major drawback of this is that when C-h becomes backspace, it no
|
|
|
748 longer invokes help. In that case, you need to use f1 for help, or
|
|
|
749 bind another key. An example of the latter is the following code,
|
|
|
750 which moves help to Meta-? (ESC ?):
|
|
124
|
751
|
|
424
|
752 (global-set-key "\M-?" 'help-command)
|
|

|
753

|
754 *** Mail agents (VM, Gnus, rmail) cannot get new mail
|
|
197
|
755
|
|
|
756 rmail and VM get new mail from /usr/spool/mail/$USER using a program
|
|
|
757 called `movemail'. This program interlocks with /bin/mail using the
|
|
|
758 protocol defined by /bin/mail.
|
|
|
759
|
|
|
760 There are two different protocols in general use. One of them uses
|
|
|
761 the `flock' system call. The other involves creating a lock file;
|
|
|
762 `movemail' must be able to write in /usr/spool/mail in order to do
|
|
|
763 this. You control which one is used by defining, or not defining, the
|
|
|
764 macro MAIL_USE_FLOCK in config.h or the m- or s- file it includes. IF
|
|
|
765 YOU DON'T USE THE FORM OF INTERLOCKING THAT IS NORMAL ON YOUR SYSTEM,
|
|
|
766 YOU CAN LOSE MAIL!
|
|
|
767
|
|
|
768 If your system uses the lock file protocol, and fascist restrictions
|
|
|
769 prevent ordinary users from writing the lock files in /usr/spool/mail,
|
|
|
770 you may need to make `movemail' setgid to a suitable group such as
|
|
|
771 `mail'. To do this, use the following commands (as root) after doing
|
|
|
772 the make install.
|
|
|
773
|
|
|
774 chgrp mail movemail
|
|
|
775 chmod 2755 movemail
|
|
|
776
|
|
|
777 Installation normally copies movemail from the build directory to an
|
|
|
778 installation directory which is usually under /usr/local/lib. The
|
|
|
779 installed copy of movemail is usually in the directory
|
|
|
780 /usr/local/lib/emacs/VERSION/TARGET. You must change the group and
|
|
|
781 mode of the installed copy; changing the group and mode of the build
|
|
|
782 directory copy is ineffective.

|
373
|
784 *** VM appears to hang in large folders.
|
|
124
|
785
|

|
786 This is normal (trust us) when upgrading to VM-6.22 from earlier
|
|
|
787 versions. Let VM finish what it is doing and all will be well.

|
|
|
793 fix this, do `M-x byte-recompile-directory' and specify the directory

794 that contains the Lisp files.

801

197

802 The fonts of the "bold" and "italic" faces are generated from the font
|
|
|
803 of the "default" face; in this way, your bold and italic fonts will
|
|
|
804 have the appropriate size and family. However, emacs can only be
|
|
|
805 clever in this way if you have specified the default font using the
|
|
|
806 XLFD (X Logical Font Description) format, which looks like
|
|
0
|
807
|
|
|
808 *-courier-medium-r-*-*-*-120-*-*-*-*-*-*
|

809

816
|
|

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

820 xfontsel(1).

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

0
|
823
|
|
|
824 Two causes have been seen for such problems.
|
|
|
825
|
|
|
826 1) On a system where getpagesize is not a system call, it is defined
|
|
|
827 as a macro. If the definition (in both unexec.c and malloc.c) is wrong,
|
|
|
828 it can cause problems like this. You might be able to find the correct
|
|
|
829 value in the man page for a.out (5).
|
|
|
830
|
|
|
831 2) Some systems allocate variables declared static among the
|
|
|
832 initialized variables. Emacs makes all initialized variables in most
|
|
|
833 of its files pure after dumping, but the variables declared static and
|
|
|
834 not initialized are not supposed to be pure. On these systems you
|
|
|
835 may need to add "#define static" to the m- or the s- file.
|
|
|
836
|
|

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

|
|
|
840 There is a problem with file-locking on some systems (possibly related
|
|
454
|
841 to NFS) that I don't understand. Please send mail to the address

|
844 *** When emacs starts up, I get lots of warnings about unknown keysyms.
|
|
124
|
845
|
|
|
846 If you are running the prebuilt binaries, the Motif library expects to find
|
|
|
847 certain thing in the XKeysymDB file. This file is normally in /usr/lib/X11/
|
|
|
848 or in /usr/openwin/lib/. If you keep yours in a different place, set the
|
|
454
|
849 environment variable $XKEYSYMDB to point to it before starting emacs. If
|
|
|
850 you still have the problem after doing that, perhaps your version of X is
|
|
124
|
851 too old. There is a copy of the MIT X11R5 XKeysymDB file in the emacs `etc'
|
|
|
852 directory. Try using that one.

|

197

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

866 most window managers don't implement them correctly.

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

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

886 *** Emacs spontaneously displays "I-search: " at the bottom of the screen.
|
|
0
|
887
|
|
|
888 This means that Control-S/Control-Q (XON/XOFF) "flow control" is being
|
|
|
889 used. C-s/C-q flow control is bad for Emacs editors because it takes
|
|
|
890 away C-s and C-q as user commands. Since editors do not output long
|
|
|
891 streams of text without user commands, there is no need for a
|
|
|
892 user-issuable "stop output" command in an editor; therefore, a
|
|
|
893 properly designed flow control mechanism would transmit all possible
|
|
|
894 input characters without interference. Designing such a mechanism is
|
|
|
895 easy, for a person with at least half a brain.
|
|
|
896
|
|
|
897 There are three possible reasons why flow control could be taking place:
|
|
|
898
|
|
|
899 1) Terminal has not been told to disable flow control
|
|
|
900 2) Insufficient padding for the terminal in use
|
|
|
901 3) Some sort of terminal concentrator or line switch is responsible
|
|
|
902
|
|
|
903 First of all, many terminals have a set-up mode which controls whether
|
|
|
904 they generate XON/XOFF flow control characters. This must be set to
|
|
|
905 "no XON/XOFF" in order for Emacs to work. Sometimes there is an
|
|
|
906 escape sequence that the computer can send to turn flow control off
|
|
|
907 and on. If so, perhaps the termcap `ti' string should turn flow
|
|
|
908 control off, and the `te' string should turn it on.
|
|
|
909
|
|
|
910 Once the terminal has been told "no flow control", you may find it
|
|
|
911 needs more padding. The amount of padding Emacs sends is controlled
|
|
|
912 by the termcap entry for the terminal in use, and by the output baud
|
|
|
913 rate as known by the kernel. The shell command `stty' will print
|
|
|
914 your output baud rate; `stty' with suitable arguments will set it if
|
|
|
915 it is wrong. Setting to a higher speed causes increased padding. If
|
|
|
916 the results are wrong for the correct speed, there is probably a
|
|
|
917 problem in the termcap entry. You must speak to a local Unix wizard
|
|
|
918 to fix this. Perhaps you are just using the wrong terminal type.
|
|
|
919
|
|
|
920 For terminals that lack a "no flow control" mode, sometimes just
|
|
|
921 giving lots of padding will prevent actual generation of flow control
|
|
|
922 codes. You might as well try it.
|
|
|
923
|
|
|
924 If you are really unlucky, your terminal is connected to the computer
|
|
|
925 through a concentrator which sends XON/XOFF flow control to the
|
|
|
926 computer, or it insists on sending flow control itself no matter how
|
|
|
927 much padding you give it. Unless you can figure out how to turn flow
|
|
|
928 control off on this concentrator (again, refer to your local wizard),
|
|
|
929 you are screwed! You should have the terminal or concentrator
|
|
|
930 replaced with a properly designed one. In the mean time, some drastic
|
|
|
931 measures can make Emacs semi-work.
|
|
|
932
|
|
|
933 You can make Emacs ignore C-s and C-q and let the operating system
|
|
|
934 handle them. To do this on a per-session basis, just type M-x
|
|
|
935 enable-flow-control RET. You will see a message that C-\ and C-^ are
|
|
|
936 now translated to C-s and C-q. (Use the same command M-x
|
|
|
937 enable-flow-control to turn *off* this special mode. It toggles flow
|
|
|
938 control handling.)
|
|
|
939
|
|
|
940 If C-\ and C-^ are inconvenient for you (for example, if one of them
|
|
|
941 is the escape character of your terminal concentrator), you can choose
|
|
|
942 other characters by setting the variables flow-control-c-s-replacement
|
|
|
943 and flow-control-c-q-replacement. But choose carefully, since all
|
|
|
944 other control characters are already used by emacs.
|
|
|
945
|
|
|
946 IMPORTANT: if you type C-s by accident while flow control is enabled,
|
|
|
947 Emacs output will freeze, and you will have to remember to type C-q in
|
|
|
948 order to continue.
|
|
|
949
|
|
|
950 If you work in an environment where a majority of terminals of a
|
|
|
951 certain type are flow control hobbled, you can use the function
|
|
|
952 `enable-flow-control-on' to turn on this flow control avoidance scheme
|
|
|
953 automatically. Here is an example:
|
|
|
954
|
|
|
955 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")
|
|
|
956
|
|
|
957 If this isn't quite correct (e.g. you have a mixture of flow-control hobbled
|
|
|
958 and good vt200 terminals), you can still run enable-flow-control
|
|
|
959 manually.
|
|
|
960
|
|
|
961 I have no intention of ever redesigning the Emacs command set for the
|
|
|
962 assumption that terminals use C-s/C-q flow control. XON/XOFF flow
|
|
|
963 control technique is a bad design, and terminals that need it are bad
|
|
|
964 merchandise and should not be purchased. Now that X is becoming
|
|
|
965 widespread, XON/XOFF seems to be on the way out. If you can get some
|
|
|
966 use out of GNU Emacs on inferior terminals, more power to you, but I
|
|
|
967 will not make Emacs worse for properly designed systems for the sake
|
|
|
968 of inferior systems.

970 *** Control-S and Control-Q commands are ignored completely.
|
|
0
|
971
|
|
|
972 For some reason, your system is using brain-damaged C-s/C-q flow
|
|
|
973 control despite Emacs's attempts to turn it off. Perhaps your
|
|
|
974 terminal is connected to the computer through a concentrator
|
|
|
975 that wants to use flow control.
|
|
|
976
|
|
|
977 You should first try to tell the concentrator not to use flow control.
|
|
|
978 If you succeed in this, try making the terminal work without
|
|
|
979 flow control, as described in the preceding section.
|
|
|
980
|
|
|
981 If that line of approach is not successful, map some other characters
|
|
|
982 into C-s and C-q using keyboard-translate-table. The example above
|
|
|
983 shows how to do this with C-^ and C-\.

988 Some versions of rlogin (and possibly telnet) do not pass flow
|
|
|
989 control characters to the remote system to which they connect.
|
|
|
990 On such systems, emacs on the remote system cannot disable flow
|
|
|
991 control on the local system.
|
|
|
992
|
|
|
993 One way to cure this is to disable flow control on the local host
|
|
|
994 (the one running rlogin, not the one running rlogind) using the
|
|
|
995 stty command, before starting the rlogin process. On many systems,
|
|
120
|
996 `stty start u stop u' will do this.
|
|
0
|
997
|
|
|
998 Some versions of tcsh will prevent even this from working. One way
|
|
|
999 around this is to start another shell before starting rlogin, and
|
|
|
1000 issue the stty command to disable flow control from that shell.
|
|
|
1001
|
|
|
1002 If none of these methods work, the best solution is to type
|
|
120
|
1003 `M-x enable-flow-control' at the beginning of your emacs session, or
|
|
0
|
1004 if you expect the problem to continue, add a line such as the
|
|
|
1005 following to your .emacs (on the host running rlogind):
|
|
|
1006
|
|
|
1007 (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")

|

197

1013
|
|
|
1014 XEmacs has fairly new TTY redisplay support (beginning from 19.12),
|
|
|
1015 which doesn't include some basic TTY optimizations -- like using
|
|
|
1016 scrolling regions to move around blocks of text. This is why
|
|
454
|
1017 redisplay on the traditional terminals, or over slow lines can be very
|
|
197
|
1018 slow.

120
|
1025 This could mean that the termcap entry you are using for that terminal

1027 combination of features specified for that terminal.
|

0
|
1028
|
|
|
1029 The first step in tracking this down is to record what characters
|
|
|
1030 Emacs is sending to the terminal. Execute the Lisp expression
|
|
120
|
1031 (open-termscript "./emacs-script") to make Emacs write all terminal
|
|
|
1032 output into the file ~/emacs-script as well; then do what makes the
|
|
|
1033 screen update wrong, and look at the file and decode the characters
|
|
|
1034 using the manual for the terminal. There are several possibilities:
|
|
0
|
1035
|
|
|
1036 1) The characters sent are correct, according to the terminal manual.
|
|
|
1037
|
|
|
1038 In this case, there is no obvious bug in Emacs, and most likely you
|
|
|
1039 need more padding, or possibly the terminal manual is wrong.
|
|
|
1040
|
|
120
|
1041 2) The characters sent are incorrect, due to an obscure aspect of the
|
|
|
1042 terminal behavior not described in an obvious way by termcap.
|
|
0
|
1043
|
|
120
|
1044 This case is hard. It will be necessary to think of a way for Emacs
|
|
|
1045 to distinguish between terminals with this kind of behavior and other
|
|
|
1046 terminals that behave subtly differently but are classified the same
|
|
|
1047 by termcap; or else find an algorithm for Emacs to use that avoids the
|
|
|
1048 difference. Such changes must be tested on many kinds of terminals.
|
|
0
|
1049
|
|
|
1050 3) The termcap entry is wrong.
|
|
|
1051
|
|
120
|
1052 See the file etc/TERMS for information on changes that are known to be
|
|
|
1053 needed in commonly used termcap entries for certain terminals.
|
|
0
|
1054
|
|
120
|
1055 4) The characters sent are incorrect, and clearly cannot be right for
|
|
|
1056 any terminal with the termcap entry you were using.
|

0
|
1057
|
|
120

1058 This is unambiguously an Emacs bug, and can probably be fixed in

1069

1071 You can tell it to obey them with this command in your `.twmrc' file:

1077
|
|
|
1078 This has been traced to communicating with your machine via kermit,
|
|
|
1079 with C-\ as the kermit escape character. One solution is to use
|
|
|
1080 another escape character in kermit. One user did
|

|
1081
|
|
|
1082 set escape-character 17
|
|
|
1083

|
|
1093 do not yet know what. If it is an Emacs bug, we hope someone can
|
|
|
1094 explain what the bug is so we can fix it. In the mean time, removing

1095 the resource prevents the problem.

1097 *** After running emacs once, subsequent invocations crash.

|
|
|
1102
|
|
|
1103 Contact your vendor and ask for the mmap bug fix; in the mean time,
|
|
|
1104 you may be able to work around the problem by adding a line to your
|
|
|
1105 operating system description file (whose name is reported by the
|
|
|
1106 configure script) that reads:
|
|
|
1107 #define SYSTEM_MALLOC
|
|
|
1108 This makes Emacs use memory less efficiently, but seems to work around
|
|

1109 the kernel bug.

1111 *** Inability to send an Alt-modified key, when Emacs is communicating
|
|
|
1112 directly with an X server.
|
|
|
1113
|
|
|
1114 If you have tried to bind an Alt-modified key as a command, and it
|
|
|
1115 does not work to type the command, the first thing you should check is
|
|
|
1116 whether the key is getting through to Emacs. To do this, type C-h c
|
|
|
1117 followed by the Alt-modified key. C-h c should say what kind of event
|
|
|
1118 it read. If it says it read an Alt-modified key, then make sure you
|
|
|
1119 have made the key binding correctly.
|
|
|
1120
|
|
|
1121 If C-h c reports an event that doesn't have the Alt modifier, it may
|
|
|
1122 be because your X server has no key for the Alt modifier. The X
|
|
|
1123 server that comes from MIT does not set up the Alt modifier by
|
|
|
1124 default.
|
|
|
1125
|
|
|
1126 If your keyboard has keys named Alt, you can enable them as follows:
|
|
|
1127
|
|
|
1128 xmodmap -e 'add mod2 = Alt_L'
|
|
|
1129 xmodmap -e 'add mod2 = Alt_R'
|
|
|
1130
|
|
|
1131 If the keyboard has just one key named Alt, then only one of those
|
|
|
1132 commands is needed. The modifier `mod2' is a reasonable choice if you
|
|
|
1133 are using an unmodified MIT version of X. Otherwise, choose any
|
|
|
1134 modifier bit not otherwise used.
|
|
|
1135
|
|
|
1136 If your keyboard does not have keys named Alt, you can use some other
|
|
|
1137 keys. Use the keysym command in xmodmap to turn a function key (or
|
|
|
1138 some other 'spare' key) into Alt_L or into Alt_R, and then use the
|
|
|
1139 commands show above to make them modifier keys.
|
|
|
1140
|
|
|
1141 Note that if you have Alt keys but no Meta keys, Emacs translates Alt
|
|
|
1142 into Meta. This is because of the great importance of Meta in Emacs.

|
|
1143
|
|
|
1144 *** In Shell mode, you get a ^M at the end of every line.
|
|
|
1145
|
|
|
1146 This happens to people who use tcsh, because it is trying to be too
|
|
|
1147 smart. It sees that the Shell uses terminal type `unknown' and turns
|
|
|
1148 on the flag to output ^M at the end of each line. You can fix the
|
|
|
1149 problem by adding this to your .cshrc file:
|
|
|
1150
|
|
|
1151 if ($?EMACS) then
|
|
|
1152 if ($EMACS == "t") then

|
|
|
1177 using XSendEvent. Allowing emacs to react to synthetic events is a
|
|
|
1178 security hole, so this is turned off by default. You can enable it by
|
|
|
1179 setting the variable x-allow-sendevents to t. You can also cause fix
|
|
|
1180 this by telling OLWM to not grab the help key, with the null binding

1186 The cause of this is a shell startup file that sets the TERMCAP

1187 environment variable. The terminal emulator uses that variable to
|
|
|
1188 provide the information on the special terminal type that Emacs
|
|

1189 emulates.
|
|
|
1190
|
|
|
1191 Rewrite your shell startup file so that it does not change TERMCAP
|
|
|
1192 in such a case. You could use the following conditional which sets
|
|
|
1193 it only if it is undefined.
|
|
|
1194
|
|
|
1195 if ( ! ${?TERMCAP} ) setenv TERMCAP ~/my-termcap-file
|
|
|
1196

1284 now explicitly forbidden in ANSI preprocessors, namely substitution

1286 workaround for this problem. Lucid's C compiler is shipped with a new

|
|
1324 Be sure also to edit x/config/cf/sun.cf so that OSMinorVersion is 4

1325 (as it should be for Solaris 2.4). The file has three definitions for
|

|

0
|
1356
|
|
124
|
1357 Many emacs mail user agents (VM and rmail, for instance) use the
|
|
|
1358 sendmail.el library. This library can arrange for mail to be
|
|
|
1359 delivered by passing messages to the /usr/lib/sendmail (usually)
|
|
|
1360 program . In doing so, it passes the '-t' flag to sendmail, which
|
|
|
1361 means that the name of the recipient of the message is not on the
|
|
|
1362 command line and, therefore, that sendmail must parse the message to
|
|
|
1363 obtain the destination address.
|
|
|
1364
|
|
|
1365 There is a bug in the SunOS4.1.1 and SunOS4.1.3 versions of sendmail.
|
|
|
1366 In short, when given the -t flag, the SunOS sendmail won't recognize
|
|
|
1367 non-local (i.e. NIS) aliases. It has been reported that the Solaris
|
|
|
1368 2.x versions of sendmail do not have this bug. For those using SunOS
|
|
|
1369 4.1, the best fix is to install sendmail V8 or IDA sendmail (which
|
|
|
1370 have other advantages over the regular sendmail as well). At the time
|
|
|
1371 of this writing, these official versions are available:
|
|
|
1372
|
|
|
1373 Sendmail V8 on ftp.cs.berkeley.edu in /ucb/sendmail:

1386
|

124
|
1387 This typically happens on Suns and other systems that use shared
|
|
|
1388 libraries. The cause is that the site has installed a version of the
|
|
|
1389 shared library which uses a name server--but has not installed a
|
|
|
1390 similar version of the unshared library which Emacs uses.

|
1391
|
|
124

1392 The result is that most programs, using the shared library, work with
|
|
|
1393 the nameserver, but Emacs does not.
|
|
|
1394
|
|
|
1395 The fix is to install an unshared library that corresponds to what you
|
|

1396 installed in the shared library, and then relink Emacs.

|
1400 If you have already installed the name resolver in the file libresolv.a,
|
|
|
1401 then you need to compile Emacs to use that library. The easiest way to
|
|
|
1402 do this is to add to config.h a definition of LIBS_SYSTEM, LIBS_MACHINE
|
|
|
1403 or LIB_STANDARD which uses -lresolv. Watch out! If you redefine a macro
|
|
|
1404 that is already in use in your configuration to supply some other libraries,
|
|
|
1405 be careful not to lose the others.
|
|
|
1406
|
|
|
1407 Thus, you could start by adding this to config.h:
|
|
|
1408
|
|
|
1409 #define LIBS_SYSTEM -lresolv
|
|
|
1410
|
|
|
1411 Then if this gives you an error for redefining a macro, and you see that
|
|
|
1412 the s- file defines LIBS_SYSTEM as -lfoo -lbar, you could change config.h
|
|
|
1413 again to say this:
|
|
|
1414
|
|
|
1415 #define LIBS_SYSTEM -lresolv -lfoo -lbar

|

|
|
|
1420 On SunOS systems, this problem has been seen to be a result of an
|
|
|
1421 incomplete installation of gcc 2.2 which allowed some non-ANSI
|
|
|
1422 compatible include files into the compilation. In particular this
|
|

1423 affected virtually all ioctl() calls.

1427 *** XEmacs crashes on startup, in make-frame.
|
|

1428
|

1429 Typically the Lisp backtrace includes
|
|
|
1430
|
|
|
1431 make-frame(nil #<x-device on ":0.0" 0x2558>)
|
|
|
1432
|
|
|
1433 somewhere near the top. The problem is due to an improvement in GNU
|
|
|
1434 ld that sorts the ELF reloc sections in the executable, giving
|
|
|
1435 dramatic speedups in startup for large executables. It also confuses
|
|
|
1436 the traditional unexec code in XEmacs, leading to the core dump. The
|
|
|
1437 solution is to use the --pdump or --ldflags='-z nocombreloc' options
|
|
|
1438 to configure. Recent 21.4 and 12.5 autodetect this in configure.
|
|
|
1439
|
|
|
1440 Red Hat and SuSE (at least) distributed a prerelease version of ld
|
|
|
1441 (versions around 2.11.90.x.y) where autodetection is impossible. The
|
|
|
1442 recommended procedure is to upgrade to binutils >= 2.12 and rerun
|
|
|
1443 configure. Otherwise you must apply the flags by hand. --pdump is
|
|
|
1444 recommended.

1446 *** I want XEmacs to use the Alt key, not the XXX key, for Meta commands
|
|
|
1447
|
|
|
1448 For historical reasons, XEmacs looks for a Meta key, then an Alt key.
|
|
|
1449 It binds Meta commands to the X11 modifier bit attached to the first
|
|
|
1450 of these it finds. On PCs, the Windows key is often assigned the Meta
|
|
|
1451 bit, but many desktop environments go to great lengths to get all apps
|
|
|
1452 to use the Alt key, and reserve the Windows key to (sensibly enough)
|
|
|
1453 the window manager.
|
|
|
1454
|
|
|
1455 One correct way to implement this was suggested on comp.emacs.xemacs
|
|
|
1456 (by Kilian Foth and in more detail by Michael Piotrowski): unmap the
|
|
|
1457 Meta modifier using xmodmap or xkb, and then map the Meta/Windows key
|
|
450
|
1458 to the Super or Hyper keysym and an appropriate mod bit. XEmacs will
|
|
|
1459 not find the Meta keysym, and default to using the Alt key for Meta
|
|
|
1460 keybindings. Typically few applications use the (X11) Meta modifier;
|
|
|
1461 it is tedious but not too much so to teach the ones you need to use
|
|
|
1462 Super instead of Meta. There may be further useful hints in the
|
|
|
1463 discussion of keymapping on non-Linux platforms.

|
1465 *** The color-gcc wrapper
|
|
|
1466
|
|
|
1467 This wrapper colorizes the error messages from gcc. By default XEmacs
|
|
|
1468 does not interpret the escape sequences used to generate colors,
|
|
|
1469 resulting in a cluttered, hard-to-read buffer. You can remove the
|
|
|
1470 wrapper, or defeat the wrapper colorization in Emacs process buffers
|
|
|
1471 by editing the "nocolor" attribute in /etc/colorgccrc:
|
|
|
1472
|
|
|
1473 $ diff -u /etc/colorgccrc.old /etc/colorgccrc

1488 *** Slow startup on Linux.
|
|
|
1489
|
|
|
1490 People using systems based on the Linux kernel sometimes report that
|
|
448
|
1491 startup takes 10 to 15 seconds longer than `usual'. There are two
|
|
|
1492 problems, one older, one newer.

|
|
|
1494 **** Old problem: IPv4 host lookup
|
|
373
|
1495
|
|
448
|
1496 On older systems, this is because Emacs looks up the host name when it
|
|
|
1497 starts. Normally, this takes negligible time; the extra delay is due
|
|
|
1498 to improper system configuration. (Recent Linux distros usually have
|
|
|
1499 this configuration correct "out of the box".) This problem can occur
|
|
|
1500 for both networked and non-networked machines.
|
|
373
|
1501
|
|
|
1502 Here is how to fix the configuration. It requires being root.
|
|
|
1503
|
|
448
|
1504 ***** Networked Case
|
|
373
|
1505
|
|
|
1506 First, make sure the files `/etc/hosts' and `/etc/host.conf' both
|
|
|
1507 exist. The first line in the `/etc/hosts' file should look like this
|
|
|
1508 (replace HOSTNAME with your host name):
|
|
|
1509
|
|
|
1510 127.0.0.1 localhost HOSTNAME
|
|
|
1511
|
|
|
1512 Also make sure that the `/etc/host.conf' files contains the following
|
|
|
1513 lines:
|
|
|
1514
|
|
454
|
1515 order hosts, bind
|
|
373
|
1516 multi on
|
|
|
1517
|
|
|
1518 Any changes, permanent and temporary, to the host name should be
|
|
|
1519 indicated in the `/etc/hosts' file, since it acts a limited local
|
|
|
1520 database of addresses and names (e.g., some SLIP connections
|
|
|
1521 dynamically allocate ip addresses).
|
|
|
1522
|
|
448
|
1523 ***** Non-Networked Case
|
|
373
|
1524
|
|
|
1525 The solution described in the networked case applies here as well.
|
|
|
1526 However, if you never intend to network your machine, you can use a
|
|
|
1527 simpler solution: create an empty `/etc/host.conf' file. The command
|
|
|
1528 `touch /etc/host.conf' suffices to create the file. The `/etc/hosts'
|
|
|
1529 file is not necessary with this approach.

1531 **** New problem: IPv6 CNAME lookup
|
|
|
1532
|
|
|
1533 A newer problem is due to XEmacs changing to use the modern
|
|
|
1534 getaddrinfo() interface from the older gethostbyname() interface. The
|
|
|
1535 solution above is insufficient, because getaddrinfo() by default tries
|
|
|
1536 to get IPv6 information for localhost. This always involves a dns
|
|
|
1537 lookup to get the CNAME, and the strategies above don't work. It then
|
|
724
|
1538 falls back to IPv4 behavior. This is good[tm] according the people at
|
|
|
1539 WIDE who know about IPv6.
|
|
448
|
1540
|
|
|
1541 ***** Robust network case
|
|
|
1542
|
|
|
1543 Configure your network so that there are no nameservers configured
|
|
|
1544 until the network is actually running. getaddrinfo() will not try to
|
|
|
1545 access a nameserver that isn't configured.
|
|
|
1546
|
|
|
1547 ***** Flaky network case
|
|
|
1548
|
|
|
1549 If you have a flaky modem or DSL connection that can be relied on only
|
|
|
1550 to go down whenever you want to bring XEmacs up, you need to force
|
|
|
1551 IPv4 behavior. Explicitly setting DISPLAY=127.0.0.1:0.0 (or whatever
|
|
|
1552 is appropriate) works in most cases.
|
|
|
1553
|
|
|
1554 If you cannot or do not want to do that, you can hard code IPv4
|
|
|
1555 behavior in src/process-unix.c. This is bad[tm], on your own head be
|
|
724
|
1556 it. Use the configure option `--with-ipv6-cname=no'.

1558 *** Mandrake
|
|
|
1559
|
|
|
1560 The Mandrake Linux distribution is attempting to comprehensively
|
|
|
1561 update the user interface, and make it consistent across
|
|
|
1562 applications. This is very difficult, and will occasionally cause
|
|
|
1563 conflicts with applications like Emacs with their own long-established
|
|
|
1564 interfaces. Known issues specific to Mandrake or especially common:
|
|
|
1565
|
|
|
1566 Some versions of XEmacs (21.1.9 is known) distributed with Mandrake
|
|
|
1567 were patched to make the Meta and Alt keysyms synonymous. These
|
|
|
1568 normally work as expected in the Mandrake environment. However,
|
|
|
1569 custom-built XEmacsen (including all 21.2 betas) will "inexplicably"
|
|
|
1570 not respect the "Alt-invokes-Meta-commands" convention. See "I want
|
|
|
1571 XEmacs to use the Alt key" below.
|
|
|
1572
|
|
|
1573 The color-gcc wrapper (see below) is in common use on the Mandrake
|
|
|
1574 platform.

1576 *** You get crashes in a non-C locale with Linux GNU Libc 2.0.
|
|
|
1577
|
|
|
1578 Internationalization was not the top priority for GNU Libc 2.0.
|
|
|
1579 As of this writing (1998-12-28) you may get crashes while running
|
|
|
1580 XEmacs in a non-C locale. For example, `LC_ALL=en_US xemacs' crashes
|
|
|
1581 while `LC_ALL=C xemacs' runs fine. This happens for example with GNU
|
|
|
1582 libc 2.0.7. Installing libintl.a and libintl.h built from gettext
|
|
|
1583 0.10.35 and re-building XEmacs solves the crashes. Presumably soon
|
|
|
1584 everyone will upgrade to GNU Libc 2.1 and this problem will go away.
|
|

1585
|
|
|
1586 *** `C-z', or `M-x suspend-emacs' hangs instead of suspending.
|
|
|
1587
|
|
|
1588 If you build with `gpm' support on Linux, you cannot suspend XEmacs
|
|
|
1589 because gpm installs a buggy SIGTSTP handler. Either compile with
|
|
|
1590 `--with-gpm=no', or don't suspend XEmacs on the Linux console until
|
|
|
1591 this bug is fixed.

|
1596 One user on a Linux system reported that this problem went away with
|
|
|
1597 installation of a new X server. The failing server was XFree86 3.1.1.

1603
|
|
|
1604 SGI ships a really old Xpm library in /usr/lib which does not work at
|
|
|
1605 all well with XEmacs. The solution is to install your own copy of the
|
|
|
1606 latest version of Xpm somewhere and then use the --site-includes and
|
|
|
1607 --site-libraries flags to tell configure where to find it.

1634 with large compilation buffers, or in other regex applications.
|

373
|
1635
|
|
|
1636 The default stack size under Digital Unix is rather small (2M as

1637 opposed to Solaris 8M), hosing the regexp code, which uses alloca()

1639 Workarounds:

|
312
|
1640
|
|
373
|
1641 1) Increase your stack size, using `ulimit -s 8192' or a (t)csh

1646 *** The `Alt' key doesn't behave as `Meta' when running DECwindows.
|
|
|
1647
|
|

1648 The default DEC keyboard mapping has the Alt keys set up to generate the
|
|
|
1649 keysym `Multi_key', which has a meaning to xemacs which is distinct from that
|
|
|
1650 of the `Meta_L' and `Meta-R' keysyms. A second problem is that certain keys
|
|
|
1651 have the Mod2 modifier attached to them for no adequately explored reason.
|
|
|
1652 The correct fix is to pass this file to xmodmap upon starting X:
|
|
|
1653
|
|
|
1654 clear mod2
|
|
|
1655 keysym Multi_key = Alt_L

1669 in the passwd database before dumping Emacs (say, by using

1671 in the dumped Emacs on any host but the one Emacs was dumped on.
|
|
|
1672
|
|
|
1673 The solution? Don't use expand-file-name in site-init.el, or in
|
|
|
1674 anything it loads. Yuck - some solution.
|
|

1675
|

1677 going on, and perhaps find a fix or a workaround, please let us know.
|

1678 Perhaps the YP functions cache some information, the cache is included

1686 The default HP keymap is set up to have Mod1 assigned to two different keys:
|
|
|
1687 Meta_L and Mode_switch (even though there is not actually a Mode_switch key on
|
|
|
1688 the keyboard -- it uses an "imaginary" keycode.) There actually is a reason
|
|
|
1689 for this, but it's not a good one. The correct fix is to execute this command
|
|

1690 upon starting X:

1737 *** XEmacs dumps core at startup when native audio is used. Native
|
|
|
1738 audio does not work with recent versions of HP-UX.
|
|
|
1739
|
|
|
1740 Under HP-UX 10.20 and later (e.g., HP-UX 11.XX), with native audio
|
|
|
1741 enabled, the dumped XEmacs binary ("xemacs") core dumps at startup if
|
|
|
1742 recent versions of the libAlib.sl audio shared library is used. Note
|
|
|
1743 that "temacs" will run, but "xemacs" will dump core. This, of course,
|
|
|
1744 causes the XEmacs build to fail. If GNU malloc is enabled, a stack
|
|
|
1745 trace will show XEmacs to have crashed in the "first" call to malloc().
|
|
|
1746
|
|
|
1747 This bug currently exists in all versions of XEmacs, when the undump
|
|
|
1748 mechanism is used. It is not known if using the experimental portable
|
|
|
1749 dumper will allow native audio to work.
|
|
|
1750
|
|
|
1751 **** Cause:
|
|
|
1752
|
|
|
1753 Recent versions of the HP-UX 10.20 (and later) audio shared library (in
|
|
|
1754 /opt/audio/lib), pulls in the libdce shared library, which pulls in a
|
|
|
1755 thread (libcma) library. This prevents the HP-UX undump() routine (in
|
|
|
1756 unexhp9k800.c) from properly working. What's happening is that some
|
|
|
1757 initialization routines are being called in the libcma library, *BEFORE*
|
|
|
1758 main() is called, and these initialization routines are calling
|
|
|
1759 malloc(). Unfortunately, in order for the undumper to work, XEmacs must
|
|
|
1760 adjust (move upwards) the sbrk() value *BEFORE* the first call to
|
|
|
1761 malloc(); if malloc() is called before XEmacs has properly adjusted sbrk
|
|
|
1762 (which is what is happening), dumped memory that is being used by
|
|
|
1763 XEmacs, is improperly re-allocated for use by malloc() and the dumped
|
|
|
1764 memory is corrupted. This causes XEmacs to die an horrible death.
|
|
|
1765
|
|
|
1766 It is believed that versions of the audio library past December 1998
|
|
|
1767 will trigger this problem. Under HP-UX 10.20, you probably have to
|
|
|
1768 install audio library patches to encounter this. It's probable that
|
|
|
1769 recent "fresh, out-of-the-box" HP-UX 11.XX workstations also have this
|
|
|
1770 problem. For HP-UX 10.20, it's believed that audio patch PHSS_17121 (or
|
|
|
1771 a superceeding one, like PHSS_17554, PHSS_17971, PHSS_18777, PHSS_21481,
|
|
|
1772 or PHSS_21662, etc.) will trigger this.
|
|
|
1773
|
|
|
1774 To check if your audio library will cause problems for XEmacs, run
|
|
|
1775 "chatr /opt/audio/lib/libAlib.sl". If "libdce" appears in the displayed
|
|
|
1776 shared library list, XEmacs will probably encounter problems if audio is
|
|
|
1777 enabled.
|
|
|
1778
|
|
|
1779 **** Workaround:
|
|
|
1780
|
|
|
1781 Don't enable native audio. Re-run configure without native audio
|
|
|
1782 support.
|
|
|
1783
|
|
|
1784 If your site supports it, try using NAS (Network Audio Support).
|
|
|
1785
|
|
|
1786 Try using the experimental portable dumper. It may work, or it may
|
|
|
1787 not.

1790 *** `Pid xxx killed due to text modification or page I/O error'

197

1804 execute `tty`. If you are not running the shell on a real tty then tty
|
|
|
1805 will print "not a tty". Csh expects one word in some places, but tty

|
1806 is giving it back 3.
|

1865 * Compatibility problems (with Emacs 18, GNU Emacs, or previous XEmacs/lemacs)
|
|
197
|
1866 ==============================================================================
|
|

|
1867
|
|
373
|
1868 *** "Symbol's value as variable is void: unread-command-char".
|
|
197
|
1869 "Wrong type argument: arrayp, #<keymap 143 entries>"
|
|
|
1870 "Wrong type argument: stringp, [#<keypress-event return>]"
|
|
88
|
1871
|
|
124
|
1872 There are a few incompatible changes in XEmacs, and these are the
|
|
|
1873 symptoms. Some of the emacs-lisp code you are running needs to be
|
|
|
1874 updated to be compatible with XEmacs.
|
|
|
1875
|
|
|
1876 The code should not treat keymaps as arrays (use `define-key', etc.),
|
|
|
1877 should not use obsolete variables like `unread-command-char' (use
|
|
197
|
1878 `unread-command-events'). Many (most) of the new ways of doing things
|
|
124
|
1879 are compatible in GNU Emacs and XEmacs.
|
|
88
|
1880
|
|
197
|
1881 Modern Emacs packages (Gnus, VM, W3, efs, etc) are written to support
|
|
|
1882 GNU Emacs and XEmacs. We have provided modified versions of several
|
|
|
1883 popular emacs packages (dired, etc) which are compatible with this
|
|
|
1884 version of emacs. Check to make sure you have not set your load-path
|
|
|
1885 so that your private copies of these packages are being found before
|
|
|
1886 the versions in the lisp directory.
|
|
124
|
1887
|
|
|
1888 Make sure that your load-path and your $EMACSLOADPATH environment
|
|
|
1889 variable are not pointing at an Emacs18 lisp directory. This will
|
|
|
1890 cripple emacs.

1892 ** Some packages that worked before now cause the error

223
|
1893 Wrong type argument: arrayp, #<face ... >
|
|
124
|
1894
|
|
197
|
1895 Code which uses the `face' accessor functions must be recompiled with
|
|
|
1896 xemacs 19.9 or later. The functions whose callers must be recompiled
|
|
|
1897 are: face-font, face-foreground, face-background,
|
|
|
1898 face-background-pixmap, and face-underline-p. The .elc files
|
|
|
1899 generated by version 19.9 will work in 19.6 and 19.8, but older .elc
|
|
|
1900 files which contain calls to these functions will not work in 19.9.

1902 ** Signaling: (error "Byte code stack underflow (byte compiler bug), pc 38")
|
|
88
|
1903
|
|
120
|
1904 This error is given when XEmacs 20 is compiled without MULE support
|
|
88
|
1905 but is attempting to load a .elc which requires MULE support. The fix
|
|
|
1906 is to rebytecompile the offending file.

|

1912 that comes with bbdb and use the one that comes with XEmacs.

1915 * MULE issues
|
|
197
|
1916 =============
|
|
144
|
1917
|
|
223
|
1918 ** A reminder: XEmacs/Mule work does not currently receive *any*
|
|
|
1919 funding, and all work is done by volunteers. If you think you can
|
|
|
1920 help, please contact the XEmacs maintainers.
|
|
|
1921
|
|
278
|
1922 ** XEmacs/Mule doesn't support TTY's satisfactorily.
|
|
223
|
1923
|
|
|
1924 This is a major problem, which we plan to address in a future release
|
|
|
1925 of XEmacs. Basically, XEmacs should have primitives to be told
|
|
|
1926 whether the terminal can handle international output, and which
|
|
|
1927 locale. Also, it should be able to do approximations of characters to
|
|
|
1928 the nearest supported by the locale.
|
|
|
1929
|
|
197
|
1930 ** Internationalized (Asian) Isearch doesn't work.
|
|
144
|
1931
|
|
|
1932 Currently, Isearch doesn't directly support any of the input methods
|
|
|
1933 that are not XIM based (like egg, canna and quail) (and there are
|
|
223
|
1934 potential problems with XIM version too...). If you're using egg
|
|
|
1935 there is a workaround. Hitting <RET> right after C-s to invoke
|
|
|
1936 Isearch will put Isearch in string mode, where a complete string can
|
|
|
1937 be typed into the minibuffer and then processed by Isearch afterwards.
|
|
|
1938 Since egg is now supported in the minibuffer using string mode you can
|
|
|
1939 now use egg to input your Japanese, Korean or Chinese string, then hit
|
|
|
1940 return to send that to Isearch and then use standard Isearch commands
|
|
|
1941 from there.
|
|
144
|
1942
|
|
223
|
1943 ** Using egg and mousing around while in 'fence' mode screws up my
|
|
|
1944 buffer.
|
|
144
|
1945
|
|
|
1946 Don't do this. The fence modes of egg and canna are currently very
|
|
|
1947 modal, and messing with where they expect point to be and what they
|
|
|
1948 think is the current buffer is just asking for trouble. If you're
|
|
|
1949 lucky they will realize that something is awry, and simply delete the
|
|
|
1950 fence, but worst case can trash other buffers too. We've tried to
|
|
|
1951 protect against this where we can, but there still are many ways to
|
|
|
1952 shoot yourself in the foot. So just finish what you are typing into
|
|
|
1953 the fence before reaching for the mouse.
|
|
223
|
1954
|
|
|
1955 ** Not all languages in Quail are supported like Devanagari and Indian
|
|
|
1956 languages, Lao and Tibetan.
|
|
|
1957
|
|
|
1958 Quail requires more work and testing. Although it has been ported to
|
|
|
1959 XEmacs, it works really well for Japanese and for the European
|
|
|
1960 languages.
|
|
|
1961
|
|
|
1962 ** Right-to-left mode is not yet implemented, so languages like
|
|
|
1963 Arabic, Hebrew and Thai don't work.
|
|
|
1964
|
|
|
1965 Getting this right requires more work. It may be implemented in a
|
|
|
1966 future XEmacs version, but don't hold your breath. If you know
|
|
|
1967 someone who is ready to implement this, please let us know.
|
|
|
1968
|
|
|
1969 ** We need more developers and native language testers. It's extremely
|
|
|
1970 difficult (and not particularly productive) to address languages that
|
|
|
1971 nobody is using and testing.
|
|
|
1972
|
|
|
1973 ** The kWnn and cWnn support for Chinese and Korean needs developers
|
|
|
1974 and testers. It probably doesn't work.
|
|
|
1975
|
|
|
1976 ** There are no `native XEmacs' TUTORIALs for any Asian languages,
|
|
454
|
1977 including Japanese. FSF Emacs and XEmacs tutorials are quite similar,
|
|
223
|
1978 so it should be sufficient to skim through the differences and apply
|
|
|
1979 them to the Japanese version.
|
|
|
1980
|
|
|
1981 ** We only have localized menus translated for Japanese, and the
|
|
|
1982 Japanese menus are developing bitrot (the Mule menu appears in
|
|
|
1983 English).
|
|
|
1984
|
|
|
1985 ** XIM is untested for any language other than Japanese.
