This file describes various problems that have been encountered
in compiling, installing and running GNU Emacs.
+* Building Emacs with GCC 2.9x fails in the `src' directory.
+
+This may happen if you use a development version of GNU `cpp' from one
+of the GCC snapshots around Oct 2000 and later, or from a released
+version of GCC newer than 2.95.2. The preprocessor in those versions
+expands ".." into ". .", which breaks relative file names that
+reference the parent directory.
+
+The solution is to make sure the preprocessor is run with the
+`-traditional' option. (The `configure' script should do that
+automatically with Emacs 21 and later.)
+
+Note that this problem does not pertain to the MS-Windows port of
+Emacs, since it doesn't use the preprocessor to generate Makefile's.
+
+* Building the MS-Windows port with Cygwin GCC can fail.
+
+Emacs may not build using recent Cygwin builds of GCC, such as Cygwin
+version 1.1.8, using the default configure settings. It appears to be
+necessary to specify the -mwin32 flag when compiling, and define
+__MSVCRT__, like so:
+
+ configure --with-gcc --cflags -mwin32 --cflags -D__MSVCRT__
+
+* Building the MS-Windows port with Leim fails in the `leim' directory.
+
+The error message might be something like this:
+
+ Converting d:/emacs-21.1/leim/CXTERM-DIC/4Corner.tit to quail-package...
+ Invalid ENCODE: value in TIT dictionary
+ NMAKE : fatal error U1077: '"../src/obj-spd/i386/emacs.exe"' : return code
+ '0xffffffff'
+ Stop.
+
+This can happen if the Leim distribution is unpacked with a program
+which converts the `*.tit' files to DOS-style CR-LF text format. The
+`*.tit' files in the leim/CXTERM-DIC directory require Unix-style line
+endings to compile properly, because Emacs reads them without any code
+or EOL conversions.
+
+The solution is to make sure the program used to unpack Leim does not
+change the files' line endings behind your back. The GNU FTP site has
+in the `/gnu/emacs/windows' directory a program called `djtarnt.exe'
+which can be used to unpack `.tar.gz' and `.zip' archives without
+mangling them.
+
+* Building `ctags' for MS-Windows with the MinGW port of GCC fails.
+
+This might happen due to a bug in the MinGW header assert.h, which
+defines the `assert' macro with a trailing semi-colon. The following
+patch to assert.h should solve this:
+
+*** include/assert.h.orig Sun Nov 7 02:41:36 1999
+--- include/assert.h Mon Jan 29 11:49:10 2001
+***************
+*** 41,47 ****
+ /*
+ * If not debugging, assert does nothing.
+ */
+! #define assert(x) ((void)0);
+
+ #else /* debugging enabled */
+
+--- 41,47 ----
+ /*
+ * If not debugging, assert does nothing.
+ */
+! #define assert(x) ((void)0)
+
+ #else /* debugging enabled */
+
+
+* `put-image' and `insert-image' don't work with JPEG images
+
+This can happen if Emacs is built with jpeg-6a library. Upgrading to
+jpeg-6b reportedly solves the problem.
+
+* When using Xaw3d scroll bars without arrows, the very first mouse
+click in a scroll bar might be ignored by the scroll bar widget. This
+is probably a bug in Xaw3d; when Xaw3d is compiled with arrows, the
+problem disappears.
+
+* Clicking C-mouse-2 in the scroll bar doesn't split the window.
+
+This currently doesn't work with scroll-bar widgets (and we don't know
+a good way of implementing it with widgets). If Emacs is configured
+--without-toolkit-scroll-bars, C-mouse-2 on the scroll bar does work.
+
+* Problems in Emacs built with LessTif.
+
+The problems seem to depend on the version of LessTif and the Motif
+emulation for which it is set up.
+
+To the best of our knowledge, only the Motif 1.2 emulation seemed to
+be stable enough in LessTif. Lesstif 0.92-17's Motif 1.2 emulation
+seems to work okay on FreeBSD. On GNU/Linux systems, lesstif-0.92.6
+configured with "./configure --enable-build-12 --enable-default-12" is
+reported to be the most successful. By contrast,
+lesstif-0.92.0-1.i386.rpm was reported to have problems with menu
+placement, and should probably be avoided.
+
+On some systems, even with Motif 1.2 emulation, Emacs occasionally
+locks up, grabbing all mouse and keyboard events. The mouse still
+moves, but will not go outside of the Emacs window (so you can't get
+it over the frame title barm, for instance). None of the menus are
+responsive. In addition, the keyboard will not respond. Keypresses
+are totally ignored, including Ctrl-Alt-F1 to Ctrl-Alt-F6. This means
+you can not even get to the virtual console.
+
+We still don't know what causes these problems; they are not
+reproducible on some systems, notably those used by Emacs developers.
+
+* Known problems with the MS-Windows port of Emacs 21.1.
+
+Emacs 21.1 built for MS-Windows doesn't support images, the tool bar,
+and tooltips. Support for these will be added in future versions.
+
+There are problems with display if the variable `redisplay-dont-pause'
+is set to nil (w32-win.el sets it to t by default, to avoid these
+problems). The problems include:
+
+ . No redisplay as long as help echo is displayed in the echo area,
+ e.g. if the mouse is on a mouse-sensitive part of the mode line.
+
+ . When mode line is dragged with the mouse, multiple copies of the
+ mode line are left behind, until the mouse button is released and
+ the next input event occurs.
+
+ . Window contents is not updated when text is selected by dragging
+ the mouse and the mouse is dragged below the bottom line of the
+ window. When the mouse button is released, the window display is
+ correctly updated.
+
+Again, these problems only occur if `redisplay-dont-pause' is nil.
+
+Emacs can sometimes abort when non-ASCII text, possibly with null
+characters, is copied and pasted into a buffer.
+
+An inactive cursor remains in an active window after the Windows
+Manager driven switch of the focus, until a key is pressed.
+
+* Some accented ISO-8859-1 characters or umlauts are displayed as | or _.
+
+Try other font set sizes (S-mouse-1). If the problem persists with
+other sizes as well, your text is corrupted, probably through software
+that is not 8-bit clean. If the problem goes away with another font
+size, it's probably because some fonts pretend to be ISO-8859-1 fonts
+when they are really ASCII fonts. In particular the schumacher-clean
+fonts have this bug in some versions of X.
+
+To see what glyphs are included in a font, use `xfd', like this:
+
+ xfd -fn -schumacher-clean-medium-r-normal--12-120-75-75-c-60-iso8859-1
+
+If this shows only ASCII glyphs, the font is indeed the source of the
+problem.
+
+The solution is to remove the corresponding lines from the appropriate
+`fonts.alias' file, then run `mkfontdir' in that directory, and then run
+`xset fp rehash'.
+
+* Large file support is disabled on HP-UX. See the comments in
+src/s/hpux10.h.
+
+* Crashes when displaying uncompressed GIFs with version
+libungif-4.1.0 are resolved by using version libungif-4.1.0b1.
+
+* Interrupting Cygwin port of Bash from Emacs doesn't work.
+
+Cygwin 1.x builds of the ported Bash cannot be interrupted from the
+MS-Windows version of Emacs. This is due to some change in the Bash
+port or in the Cygwin library which apparently make Bash ignore the
+keyboard interrupt event sent by Emacs to Bash. (Older Cygwin ports
+of Bash, up to b20.1, did receive SIGINT from Emacs.)
+
+* The W3 package (either from from the CVS sources or the last
+release) currently (2000-12-14) doesn't run properly with Emacs 21 and
+needs work. This patch is reported to make w3-4.0pre.46 work:

+* On systems with shared libraries you might encounter run-time errors
+from the dynamic linker telling you that it is unable to find some
+shared libraries, for instance those for Xaw3d or image support.
+These errors mean Emacs has been linked with a library whose shared
+library is not in the default search path of the dynamic linker.
+
+On many systems, it is possible to set LD_LIBRARY_PATH in your
+environment to specify additional directories where shared libraries
+can be found.
+
+Other systems allow to set LD_RUN_PATH in a similar way, but before
+Emacs is linked. With LD_RUN_PATH set, the linker will include a
+specified run-time search path in the executable.
+
+Please refer to the documentation of your dynamic linker for details.
+
+* On Solaris 2.7, building Emacs with WorkShop Compilers 5.0 98/12/15
+C 5.0 failed, apparently with non-default CFLAGS, most probably due to
+compiler bugs. Using Sun Solaris 2.7 Sun WorkShop 6 update 1 C
+release was reported to work without problems. It worked OK on
+another system with Solaris 8 using apparently the same 5.0 compiler
+and the default CFLAGS.
+
* On Windows 95/98/ME, subprocesses do not terminate properly.
This is a limitation of the Operating System, and can cause problems
This problem is fixed in Patch 3175 for Irix 5.3.
It is also fixed in Irix versions 6.2 and up.
+* The S-C-t key combination doesn't get passed to Emacs on X.
+
+This happens because some X configurations assign the Ctrl-Shift-t
+combination the same meaning as the Multi_key. The offending
+definition is in the file `...lib/X11/locale/iso8859-1/Compose'; there
+might be other similar combinations which are grabbed by X for similar
+purposes.
+
+We think that this can be countermanded with the `xmodmap' utility, if
+you want to be able to bind one of these key sequences within Emacs.
+
* On Solaris, CTRL-t is ignored by Emacs when you use
the fr.ISO-8859-15 locale (and maybe other related locales).
The intlfonts distribution includes a full spectrum of fonts that can
display all the characters Emacs supports.
+Another cause of this for specific characters is fonts which have a
+missing glyph and no default character. This is known ot occur for
+character number 160 (no-break space) in some fonts, such as Lucida
+but Emacs sets the display table for the unibyte and Latin-1 version
+of this character to display a space.
+
* Under X11, some characters appear improperly aligned in their lines.
You may have bad X11 fonts; try installing the intlfonts distribution.
