** Emacs crashes with SIGSEGV in XtInitializeWidgetClass.
This happens because of bugs in Gtk+. Gtk+ 2.10 seems to be OK. See bug
http://bugzilla.gnome.org/show_bug.cgi?id=85715.
+** Emacs compiled with Gtk+ may loop forever if a display crashes.
+
+This is related to the bug above. A scenario for this is when emacs is run
+as a server, and an X frame is created. If the X server for the frame
+crashes or exits unexpectedly and an attempt is made to create a new
+frame on another X display, then a Gtk+ error happens in the emacs
+server that results in an endless loop. This is not fixed in any known
+Gtk+ version (2.14.4 being current).
+
** Emacs compiled with Gtk+ crashes on startup on Cygwin.
A typical error message is
`mail'. To do this, use the following commands (as root) after doing the
make install.
- chgrp mail movemail
- chmod 2755 movemail
+ chgrp mail movemail
+ chmod 2755 movemail
Installation normally copies movemail from the build directory to an
installation directory which is usually under /usr/local/lib. The
The fix is to install an unshared library that corresponds to what you
installed in the shared library, and then relink Emacs.
-On SunOS 4.1, simply define HAVE_RES_INIT.
-
If you have already installed the name resolver in the file libresolv.a,
then you need to compile Emacs to use that library. The easiest way to
do this is to add to config.h a definition of LIBS_SYSTEM, LIBS_MACHINE

* Runtime problems related to font handling
-** Under X11, some characters appear as hollow boxes.
+** Characters are displayed as empty boxes or with wrong font under X.
+
+*** This can occur when two different versions of FontConfig are used.
+For example, XFree86 4.3.0 has one version and Gnome usually comes
+with a newer version. Emacs compiled with Gtk+ will then use the
+newer version. In most cases the problem can be temporarily fixed by
+stopping the application that has the error (it can be Emacs or any
+other application), removing ~/.fonts.cache-1, and then start the
+application again. If removing ~/.fonts.cache-1 and restarting
+doesn't help, the application with problem must be recompiled with the
+same version of FontConfig as the rest of the system uses. For KDE,
+it is sufficient to recompile Qt.
+
+*** Some fonts have a missing glyph and no default character. This is
+known to 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.
+
+*** Some of the fonts called for in your fontset may not exist on your
+X server.
Each X11 font covers just a fraction of the characters that Emacs
supports. To display the whole range of Emacs characters requires

by ps-print and ps-mule to print Unicode characters.

+
+** Under X, an unexpected monospace font is used as the default font.
+
+When compiled with XFT, Emacs tries to use a default font named
+"monospace". This is a "virtual font", which the operating system
+(Fontconfig) redirects to a suitable font such as DejaVu Sans Mono.
+On some systems, there exists a font that is actually named Monospace,
+which takes over the virtual font. This is considered an operating
+system bug; see
+
+http://lists.gnu.org/archive/html/emacs-devel/2008-10/msg00696.html
-** Certain fonts make each line take one pixel more than it "should".
+If you encounter this problem, set the default font to a specific font
+in your .Xresources or initialization file. For instance, you can put
+the following in your .Xresources:

-than the font's nominal height. Emacs needs to make sure that

One way to avoid this problem is to eliminate the type-1 fonts from
your font path, like this:

+*** Prevent double pastes in X
+
+The problem: a region, such as a command, is pasted twice when you copy
+it with your mouse from GNU Emacs to an xterm or an RXVT shell in X.
+The solution: try the following in your X configuration file,
+/etc/X11/xorg.conf This should enable both PS/2 and USB mice for
+single copies. You do not need any other drivers or options.

* Runtime problems on character terminals
** Emacs spontaneously displays "I-search: " at the bottom of the screen.
Using the old library version is a workaround.
-** Mac OS X
-
-*** Mac OS X (Carbon): Environment Variables from dotfiles are ignored.
-
-When starting Emacs from the Dock or the Finder on Mac OS X, the
-environment variables that are set up in dotfiles, such as .cshrc or
-.profile, are ignored. This is because the Finder and Dock are not
-started from a shell, but instead from the Window Manager itself.
-
-The workaround for this is to create a .MacOSX/environment.plist file to
-setup these environment variables. These environment variables will
-apply to all processes regardless of where they are started.
-For me information, see http://developer.apple.com/qa/qa2001/qa1067.html.
-
-*** Mac OS X (Carbon): Process output truncated when using ptys.
-
-There appears to be a problem with the implementation of pty's on the
-Mac OS X that causes process output to be truncated. To avoid this,
-leave process-connection-type set to its default value of nil.
-
-*** Mac OS X 10.3.9 (Carbon): QuickTime updater breaks build.
-
-Some QuickTime updaters such as 7.0.4 and 7.2.0 are known to break
-build at the link stage with the message like "Undefined symbols:
-_HICopyAccessibilityActionDescription referenced from QuickTime
-expected to be defined in Carbon". A workaround is to use a QuickTime
-reinstaller. Alternatively, you can link with the frameworks in the
-corresponding SDK by specifying LDFLAGS as
-"-Wl,-F/Developer/SDKs/MacOSX10.3.0.sdk/System/Library/Frameworks".
-
** FreeBSD
*** FreeBSD 2.1.5: useless symbolic links remain in /tmp or other
You can fix this by editing the file:
- /usr/openwin/lib/locale/iso8859-15/Compose
+ /usr/openwin/lib/locale/iso8859-15/Compose
Near the bottom there is a line that reads:
- Ctrl<t> <quotedbl> <Y> : "\276" threequarters
+ Ctrl<t> <quotedbl> <Y> : "\276" threequarters
that should read:
- Ctrl<T> <quotedbl> <Y> : "\276" threequarters
+ Ctrl<T> <quotedbl> <Y> : "\276" threequarters
Note the lower case <t>. Changing this line should make C-t work.
+*** On Solaris, Emacs fails to set menu-bar-update-hook on startup, with error
+"Error in menu-bar-update-hook: (error Point before start of properties)".
+This seems to be a GCC optimization bug that occurs for GCC 4.1.2 (-g
+and -g -O2) and GCC 4.2.3 (-g -O and -g -O2). You can fix this by
+compiling with GCC 4.2.3 or CC 5.7, with no optimizations.
+
** Irix
*** Irix 6.5: Emacs crashes on the SGI R10K, when compiled with GCC.
* Runtime problems specific to MS-Windows
+** PATH can contain unexpanded environment variables
+
+Old releases of TCC (version 9) and 4NT (up to version 8) do not correctly
+expand App Paths entries of type REG_EXPAND_SZ. When Emacs is run from TCC
+and such an entry exists for emacs.exe, exec-path will contain the
+unexpanded entry. This has been fixed in TCC 10. For more information,
+see bug#2062.
+
+** Setting w32-pass-rwindow-to-system and w32-pass-lwindow-to-system to nil
+does not prevent the Start menu from popping up when the left or right
+``Windows'' key is pressed.
+
+This was reported to happen when XKeymacs is installed. At least with
+XKeymacs Version 3.47, deactivating XKeymacs when Emacs is active is
+not enough to avoid its messing with the keyboard input. Exiting
+XKeymacs completely is reported to solve the problem.
+
** Windows 95 and networking.
To support server sockets, Emacs 22.1 loads ws2_32.dll. If this file
Supposedly the newer 32-bit version of this server doesn't have the
problem.
-** Known problems with the MS-Windows port of Emacs 22.1
+** Emacs crashes when opening a file with a UNC path and rails-mode is loaded.
+
+Loading rails-mode seems to interfere with UNC path handling. This has been
+reported as a bug against both Emacs and rails-mode, so look for an updated
+rails-mode that avoids this crash, or avoid using UNC paths if using
+rails-mode.
+
+** Known problems with the MS-Windows port of Emacs 22.3
+
+M-x term does not work on MS-Windows. TTY emulation on Windows is
+undocumented, and programs such as stty which are used on posix platforms
+to control tty emulation do not exist for native windows terminals.
Using create-fontset-from-ascii-font or the --font startup parameter
with a Chinese, Japanese or Korean font leads to display problems.
When "ClearType" method is selected as the "method to smooth edges of
screen fonts" (in Display Properties, Appearance tab, under
"Effects"), there are various problems related to display of
-characters: 2-pixel trace is left behind when moving overlays, bold
-fonts can be hard to read, small portions of some characters could
-appear chopped, etc. This happens because, under ClearType,
-characters are drawn outside their advertised bounding box. Emacs 21
-disabled the use of ClearType, whereas Emacs 22 allows it and has some
-code to enlarge the width of the bounding box. Apparently, this
-display feature needs more changes to get it 100% right. A workaround

*** Building the native MS-Windows port with Cygwin GCC can fail.
-Emacs may not build using recent Cygwin builds of GCC, such as Cygwin
+Emacs may not build using some 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:
to detect the shell correctly. Try "make SHELL=cmd.exe", or if that
fails, try running make from Cygwin bash instead.
-*** Building the MS-Windows port with Leim fails in the `leim' directory.
-
-The error message might be something like this:
-
- Converting d:/emacs-21.3/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
conflict between the versions of malloc in the DLL and in Emacs, which
is not resolvable due to the way Windows does dynamic linking.
-We recommend the use of the MingW port of GCC for compiling Emacs, as
+We recommend the use of the MinGW port of GCC for compiling Emacs, as
not only does it not suffer these problems, but it is also Free
software like Emacs.
+*** Building the MS-Windows port with Visual Studio fails compiling emacs.rc

+If the build fails with the following message then the problem
+described here most likely applies:
+
+../nt/emacs.rc(1) : error RC2176 : old DIB in icons\emacs.ico; pass it
+through SDKPAINT
+
+The Emacs icon contains a high resolution PNG icon for Vista, which is
+not recognized by older versions of the resource compiler. There are
+several workarounds for this problem:
+ 1. Use Free MinGW tools to compile, which do not have this problem.
+ 2. Install the latest Windows SDK.
+ 3. Replace emacs.ico with an older or edited icon.

+
+Bootstrapping (compiling the .el files) is normally only necessary

-*** SunOS
-
-SunOS 4.1.4 stopped shipping on Sep 30 1998.
-
-**** SunOS: You get linker errors
- ld: Undefined symbol
- _get_wmShellWidgetClass
- _get_applicationShellWidgetClass
-
-**** Sun 4.0.x: M-x shell persistently reports "Process shell exited abnormally with code 1".
-
-This happened on Suns as a result of what is said to be a bug in Sunos
-version 4.0.x. The only fix was to reboot the machine.
-
-**** SunOS4.1.1 and SunOS4.1.3: Mail is lost when sent to local aliases.
-
-Many emacs mail user agents (VM and rmail, for instance) use the
-sendmail.el library. This library can arrange for mail to be
-delivered by passing messages to the /usr/lib/sendmail (usually)
-program . In doing so, it passes the '-t' flag to sendmail, which
-means that the name of the recipient of the message is not on the
-command line and, therefore, that sendmail must parse the message to
-obtain the destination address.
-
-There is a bug in the SunOS4.1.1 and SunOS4.1.3 versions of sendmail.
-In short, when given the -t flag, the SunOS sendmail won't recognize
-non-local (i.e. NIS) aliases. It has been reported that the Solaris
-2.x versions of sendmail do not have this bug. For those using SunOS
-4.1, the best fix is to install sendmail V8 or IDA sendmail (which
-have other advantages over the regular sendmail as well). At the time
-of this writing, these official versions are available:
-
- Sendmail V8 on ftp.cs.berkeley.edu in /ucb/sendmail:
- sendmail.8.6.9.base.tar.Z (the base system source & documentation)
- sendmail.8.6.9.cf.tar.Z (configuration files)
- sendmail.8.6.9.misc.tar.Z (miscellaneous support programs)
- sendmail.8.6.9.xdoc.tar.Z (extended documentation, with postscript)
-
- IDA sendmail on vixen.cso.uiuc.edu in /pub:
- sendmail-5.67b+IDA-1.5.tar.gz
-
-**** Sunos 4: You get the error ld: Undefined symbol __lib_version.
-
-This is the result of using cc or gcc with the shared library meant
-for acc (the Sunpro compiler). Check your LD_LIBRARY_PATH and delete
-/usr/lang/SC2.0.1 or some similar directory.
-
-**** SunOS 4.1.3: Emacs unpredictably crashes in _yp_dobind_soft.
-
-This happens if you configure Emacs specifying just `sparc-sun-sunos4'
-on a system that is version 4.1.3. You must specify the precise
-version number (or let configure figure out the configuration, which
-it can do perfectly well for SunOS).
-
-**** Sunos 4.1.3: Emacs gets hung shortly after startup.

-**** SunOS 4: Emacs processes keep going after you kill the X server
-(or log out, if you logged in using X).
-
-Someone reported that recompiling with GCC 2.7.0 fixed this problem.
-
-The fix to this is to install patch 100573 for OpenWindows 3.0
-or link libXmu statically.
-
**** Sunos 5.3: Subprocesses remain, hanging but not zombies.
A bug in Sunos 5.3 causes Emacs subprocesses to remain after Emacs
applies to ptys, and doesn't fix the problem with subprocesses
communicating through pipes.
-*** Apollo Domain
-
-**** Shell mode ignores interrupts on Apollo Domain.
-
-You may find that M-x shell prints the following message:
-
- Warning: no access to tty; thus no job control in this shell...
-
-This can happen if there are not enough ptys on your system.
-Here is how to make more of them.
-
- % cd /dev
- % ls pty*
- # shows how many pty's you have. I had 8, named pty0 to pty7)
- % /etc/crpty 8
- # creates eight new pty's

- *Background: scoBackground

The best solution is to create an application-specific resource file for
Emacs, /usr/lib/X11/sco/startup/Emacs, with the following contents:
- Emacs*Font: -*-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-1

(These settings mimic the Emacs defaults, but you can change them to
suit your needs.) This resource file is only read when the X server

** MS-DOS
-*** When compiling with DJGPP on MS-Windows NT, "config msdos" fails.
+*** When compiling with DJGPP on MS-Windows NT or later, "config msdos" fails.
If the error message is "VDM has been already loaded", this is because
Windows has a program called `redir.exe' that is incompatible with a
config.bat. To resolve this, move the DJGPP's `bin' subdirectory to
the front of your PATH environment variable.
+*** When Emacs compiled with DJGPP runs on Windows 2000 and later, it cannot
+find your HOME directory.
+
+This was reported to happen when you click on "Save for future
+sessions" button in a Customize buffer. You might see an error
+message like this one:
+
+ basic-save-buffer-2: c:/FOO/BAR/~dosuser/: no such directory
+
+(The telltale sign is the "~USER" part at the end of the directory
+Emacs complains about, where USER is your username or the literal
+string "dosuser", which is the default username set up by the DJGPP
+startup file DJGPP.ENV.)
+
+This happens when the functions `user-login-name' and
+`user-real-login-name' return different strings for your username as
+Emacs sees it. To correct this, make sure both USER and USERNAME
+environment variables are set to the same value. Windows 2000 and
+later sets USERNAME, so if you want to keep that, make sure USER is
+set to the same value. If you don't want to set USER globally, you
+can do it in the [emacs] section of your DJGPP.ENV file.
+
+*** When Emacs compiled with DJGPP runs on Vista, it runs out of memory.
+
+If Emacs running on Vista displays "!MEM FULL!" in the mode line, you
+are hitting the memory allocation bugs in the Vista DPMI server. See
+msdos/INSTALL for how to work around these bugs (search for "Vista").

*** When compiling with DJGPP on MS-Windows 95, Make fails for some targets
like make-docfile.
This can happen if long file name support (the setting of environment
variable LFN) when Emacs distribution was unpacked and during
-compilation are not the same. See the MSDOG section of INSTALL for

Another possible reason for such failures is that Emacs compiled for
MSDOS is used on Windows NT, where long file names are not supported
However, the easiest approach is to build Xlib with the default
floating point option: -fsoft.
-** SunOS: Undefined symbols _dlopen, _dlsym and/or _dlclose.
-
-If you see undefined symbols _dlopen, _dlsym, or _dlclose when linking
-with -lX11, compile and link against the file mit/util/misc/dlsym.c in
-the MIT X11R5 distribution. Alternatively, link temacs using shared
-libraries with s/sunos4shr.h. (This doesn't work if you use the X
-toolkit.)
-
-If you get the additional error that the linker could not find
-lib_version.o, try extracting it from X11/usr/lib/X11/libvim.a in
-X11R4, then use it in the link.
-
-** SunOS4, DGUX 5.4.2: --with-x-toolkit version crashes when used with shared libraries.
-
-On some systems, including Sunos 4 and DGUX 5.4.2 and perhaps others,
-unexec doesn't work properly with the shared library for the X
-toolkit. You might be able to work around this by using a nonshared
-libXt.a library. The real fix is to upgrade the various versions of
-unexec and/or ralloc. We think this has been fixed on Sunos 4
-and Solaris in version 19.29.
-
** HPUX 10.20: Emacs crashes during dumping on the HPPA machine.
This seems to be due to a GCC bug; it is fixed in GCC 2.8.1.
-** VMS: Compilation errors on VMS.
-
-You will get warnings when compiling on VMS because there are
-variable names longer than 32 (or whatever it is) characters.
-This is not an error. Ignore it.
-
-VAX C does not support #if defined(foo). Uses of this construct
-were removed, but some may have crept back in. They must be rewritten.
-
-There is a bug in the C compiler which fails to sign extend characters
-in conditional expressions. The bug is:
- char c = -1, d = 1;
- int i;
-
- i = d ? c : d;
-The result is i == 255; the fix is to typecast the char in the
-conditional expression as an (int). Known occurrences of such
-constructs in Emacs have been fixed.
-
** Vax C compiler bugs affecting Emacs.
You may get one of these problems compiling Emacs:
In the XCONS, etc., macros in lisp.h you must replace (a).u.val with
((a).u.val + coercedummy) where coercedummy is declared as int.
-This problem will not happen if the m-...h file for your type
-of machine defines NO_UNION_TYPE. That is the recommended setting now.
+This problem will only happen if USE_LISP_UNION_TYPE is manually
+defined in lisp.h.
*** C compilers lose on returning unions.
Most of the functions in GNU Emacs return type Lisp_Object, which is
defined as a union on some rare architectures.
