This file describes various problems that have been encountered
in compiling, installing and running GNU Emacs.
+* Process output truncated on Mac OS X (Carbon) when using pty's.
+
+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.
+
+* Emacs crashes on Mac OS X (Carbon) after system software upgrade.
+
+This problem seems to be now solved by Steven Tamm's patch to
+unexmacosx.c on Nov 24, 2002.
+
+Between Mac OS X release 10.2.1 and 10.2.2 there was an incompatible
+change in the memory allocator that causes a EXC_BAD_ACCESS error near
+xrealloc(). Relinking the application (by deleting src/temacs and
+running make) will solve the problem. It appears to be caused by some
+problems with the unexec code and its interaction with libSystem.B.
+
+* Characters from the mule-unicode charsets aren't displayed under X.
+
+XFree86 4 contains many fonts in iso10646-1 encoding which have
+minimal character repertoires (whereas the encoding part of the font
+name is meant to be a reasonable indication of the repertoire
+according to the XLFD spec). Emacs may choose one of these to display
+characters from the mule-unicode charsets and then typically won't be
+able to find the glyphs to display many characters. (Check with C-u
+C-x = .) To avoid this, you may need to use a fontset which sets the
+font for the mule-unicode sets explicitly. E.g. to use GNU unifont,
+include in the fontset spec:
+
+mule-unicode-2500-33ff:-gnu-unifont-*-iso10646-1,\
+mule-unicode-e000-ffff:-gnu-unifont-*-iso10646-1,\
+mule-unicode-0100-24ff:-gnu-unifont-*-iso10646-1
+
+* The UTF-8/16/7 coding systems don't encode CJK (Far Eastern) characters.
+
+Emacs by default only supports the parts of the Unicode BMP whose code
+points are in the ranges 0000-33ff and e000-ffff. This excludes: most
+of CJK, Yi and Hangul, as well as everything outside the BMP.
+
+If you read UTF-8 data with code points outside these ranges, the
+characters appear in the buffer as raw bytes of the original UTF-8
+(composed into a single quasi-character) and they will be written back
+correctly as UTF-8, assuming you don't break the composed sequences.
+If you read such characters from UTF-16 or UTF-7 data, they are
+substituted with the Unicode `replacement character', and you lose
+information.
+
+To edit such UTF data, turn on Utf-Translate-Cjk mode, which makes
+many common CJK characters available for encoding and decoding and can
+be extended by updating the tables it uses. This also allows you to
+save as UTF buffers containing characters decoded by the chinese-,
+japanese- and korean- coding systems, e.g. cut and pasted from
+elsewhere.
+
+* Problems with file dialogs in Emacs built with Open Motif.
+
+When Emacs 21 is built with Open Motif 2.1, it can happen that the
+graphical file dialog boxes do not work properly. The "OK", "Filter"
+and "Cancel" buttons do not respond to mouse clicks. Dragging the
+file dialog window usually causes the buttons to work again.
+
+The solution is to use LessTif instead. LessTif is a free replacement
+for Motif. See the file INSTALL for information on how to do this.
+
+Another workaround is not to use the mouse to trigger file prompts,
+but to use the keyboard. This way, you will be prompted for a file in
+the minibuffer instead of a graphical file dialog.
+
+* Emacs reports a BadAtom error (from X) running on Solaris 7 or 8.
+
+This happens when Emacs was built on some other version of Solaris.
+Rebuild it on Solaris 8.
+
+* Mule-UCS loads very slowly.
+
+Changes to Emacs internals interact badly with Mule-UCS's `un-define'
+library, which is the usual interface to Mule-UCS. Apply the
+following patch to Mule-UCS 0.84 and rebuild it. That will help,
+though loading will still be slower than in Emacs 20. (Some
+distributions, such as Debian, may already have applied such a patch.)

* 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
Note that this problem does not pertain to the MS-Windows port of
Emacs, since it doesn't use the preprocessor to generate Makefiles.
+* Building Emacs with a system compiler fails to link because of an
+undefined symbol such as __eprintf which does not appear in Emacs.
+
+This can happen if some of the libraries linked into Emacs were built
+with GCC, but Emacs itself is being linked with a compiler other than
+GCC. Object files compiled with GCC might need some helper functions
+from libgcc.a, the library which comes with GCC, but the system
+compiler does not instruct the linker to search libgcc.a during the
+link stage.
+
+A solution is to link with GCC, like this:
+
+ make CC=gcc
+
+Since the .o object files already exist, this will not recompile Emacs
+with GCC, but just restart by trying again to link temacs.
+
* Building the MS-Windows port with Cygwin GCC can fail.
Emacs may not build using recent Cygwin builds of GCC, such as Cygwin
The error message might be something like this:

-* Improving performance with slow X connections
-If you don't need X Input Methods (XIM) for entering text in some
-language you use, you can improve performance on WAN links by
-configuring Emacs with option `--without-xim'. Configuring Emacs
-without XIM does not affect the use of Emacs' own input methods, which
-are part of the Leim package.
+* Improving performance with slow X connections
-If the connection is very slow, you might also want to consider
-switching off scroll bars, menu bar, and tool bar.
+There are several ways to improve this performance, any subset of which can
+be carried out at the same time:
+
+1) If you don't need X Input Methods (XIM) for entering text in some
+ language you use, you can improve performance on WAN links by using
+ the X resource useXIM to turn off use of XIM. This does not affect
+ the use of Emacs' own input methods, which are part of the Leim
+ package.
+
+2) If the connection is very slow, you might also want to consider
+ switching off scroll bars, menu bar, and tool bar.
+
+3) Use ssh to forward the X connection, and enable compression on this
+ forwarded X connection (ssh -XC remotehostname emacs ...).
+
+4) Use lbxproxy on the remote end of the connection. This is an interface
+ to the low bandwidth X extension in most modern X servers, which
+ improves performance dramatically, at the slight expense of correctness
+ of the X protocol. lbxproxy acheives the performance gain by grouping
+ several X requests in one TCP packet and sending them off together,
+ instead of requiring a round-trip for each X request in a seperate
+ packet. The switches that seem to work best for emacs are:
+ -noatomsfile -nowinattr -cheaterrors -cheatevents
+ Note that the -nograbcmap option is known to cause problems.
+ For more about lbxproxy, see:
+ http://www.xfree86.org/4.3.0/lbxproxy.1.html
* Getting a Meta key on the FreeBSD console
is probably a bug in Xaw3d; when Xaw3d is compiled with arrows, the
problem disappears.
+* There are known binary incompatibilities between Xaw, Xaw3d, neXtaw,
+XawM and the few other derivatives of Xaw. So when you compile with
+one of these, it may not work to dynamically link with another one.
+For example, strange problems, such as Emacs exiting when you type
+"C-x 1", were reported when Emacs compiled with Xaw3d and libXaw was
+used with neXtaw at run time.
+
+The solution is to rebuild Emacs with the toolkit version you actually
+want to use, or set LD_PRELOAD to preload the same toolkit version you
+built Emacs with.
+
* 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.
+* Emacs aborts inside the function `tparam1'.
+
+This can happen if Emacs was built without terminfo support, but the
+terminal's capabilities use format that is only supported by terminfo.
+If your system has ncurses installed, this might happen if your
+version of ncurses is broken; upgrading to a newer version of ncurses
+and reconfiguring and rebuilding Emacs should solve this.
+
+All modern systems support terminfo, so even if ncurses is not the
+problem, you should look for a way to configure Emacs so that it uses
+terminfo when built.
+
+* Error messages about undefined colors on X.
+
+The messages might say something like this:
+
+ Unable to load color "grey95"
+
+(typically, in the `*Messages*' buffer), or something like this:
+
+ Error while displaying tooltip: (error Undefined color lightyellow)
+
+These problems could happen if some other X program has used up too
+many colors of the X palette, leaving Emacs with insufficient system
+resources to load all the colors it needs.
+
+A solution is to exit the offending X programs before starting Emacs.
+
* Colors are not available on a tty or in xterm.
Emacs 21 supports colors on character terminals and terminal
`xterm-color' might activate the color support on an xterm-compatible
emulator.
+Beginning with version 21.4, Emacs supports the --color command-line
+option which may be used to force Emacs to use one of a few popular
+modes for getting colors on a tty. For example, --color=ansi8 sets up
+for using the ANSI-standard escape sequences that support 8 colors.
+
Some modes do not use colors unless you turn on the Font-lock mode.
Some people have long ago set their `~/.emacs' files to turn on
Font-lock on X only, so they won't see colors on a tty. The
global-font-lock-mode RET" or by customizing the variable
`global-font-lock-mode'.
+* Emacs on a tty switches the cursor to large blinking block.
+
+This was reported to happen on some GNU/Linux systems which use
+ncurses version 5.0, but could be relevant for other versions as well.
+These versions of ncurses come with a `linux' terminfo entry, where
+the "cvvis" capability (termcap "vs") is defined as "\E[?25h\E[?8c"
+(show cursor, change size). This escape sequence switches on a
+blinking hardware text-mode cursor whose size is a full character
+cell. This blinking cannot be stopped, since a hardware cursor
+always blinks.
+
+A work-around is to redefine the "cvvis" capability so that it
+enables a *software* cursor. The software cursor works by inverting
+the colors of the character at point, so what you see is a block
+cursor that doesn't blink. For this to work, you need to redefine
+the "cnorm" capability as well, so that it operates on the software
+cursor instead of the hardware cursor.
+
+To this end, run "infocmp linux > linux-term", edit the file
+`linux-term' to make both the "cnorm" and "cvvis" capabilities send
+the sequence "\E[?25h\E[?17;0;64c", and then run "tic linux-term" to
+produce a modified terminfo entry.
+
+Alternatively, if you want a blinking underscore as your Emacs cursor,
+change the "cvvis" capability to send the "\E[?25h\E[?0c" command.
+
* Problems in Emacs built with LessTif.
The problems seem to depend on the version of LessTif and the Motif
what causes these problems; they are not reproducible 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.
-
-Help text that is displayed in a tooltip on other window systems, on
-Windows is printed in the echo area, since tooltips are not yet
-available. Help text for menu items is not displayed at all.
-
-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:
+* Known problems with the MS-Windows port of Emacs 21.2.
- . 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.
+Frames are not refreshed while the File or Font dialog or a pop-up menu
+is displayed. This also means help text for pop-up menus is not
+displayed at all. This is because message handling under Windows is
+synchronous, so we cannot handle repaint (or any other) messages while
+waiting for a system function to return the result of the dialog or
+pop-up menu interaction.
- . When the 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.
+Windows 95 and Windows NT up to version 4.0 do not support help text
+for menus. Help text is only available in later versions of Windows.
- . Window contents are 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.
+There are problems with display if mouse-tracking is enabled and the
+mouse is moved off a frame, over another frame then back over the first
+frame. A workaround is to click the left mouse button inside the frame
+after moving back into it.
-Again, these problems only occur if `redisplay-dont-pause' is nil.
+Some minor flickering still persists during mouse-tracking, although
+not as severely as in 21.1.
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.
-Windows 2000 input methods are not recognized by Emacs (as of v21.1).
-These input methods cause the keyboard to send characters encoded in
-the appropriate coding system (e.g., ISO 8859-1 for Latin-1
+Windows input methods are not recognized by Emacs (as of v21.2). Some
+of these input methods cause the keyboard to send characters encoded
+in the appropriate coding system (e.g., ISO 8859-1 for Latin-1
characters, ISO 8859-8 for Hebrew characters, etc.). To make this
work, set the keyboard coding system to the appropriate value after
you activate the Windows input method. For example, if you activate
appropriate keyboard encoding automatically, but it doesn't do that
yet.)
-Multilingual text put into the Windows 2000 clipboard by Windows
-applications cannot be safely pasted into Emacs (as of v21.1). This
-is because Windows 2000 uses Unicode to represent multilingual text,
-but Emacs does not yet support Unicode well enough to decode it. This
-means that Emacs can only interchange non-ASCII text with other
-Windows 2000 programs if the characters are in the system codepage.
-Reportedly, a partial solution is to install the Mule-UCS package and
-set selection-coding-system to utf-16-le-dos.
+Windows uses UTF-16 encoding to deal with multilingual text (text not
+encodable in the `system codepage') in the clipboard. To deal with
+this, load the library `utf-16' and use `set-selection-coding-system'
+to set the clipboard coding system to `utf-16-le-with-signature-dos'.
-* The `configure' script doesn't find the jpeg library.
+The %b specifier for format-time-string does not produce abbreviated
+month names with consistent widths for some locales on some versions
+of Windows. This is caused by a deficiency in the underlying system
+library function.
-This can happen because the linker by default only looks for shared
-libraries, but jpeg distribution by default doesn't build and doesn't
-install a shared version of the library, `libjpeg.so'. One system
-where this is known to happen is Compaq OSF/1 (`Tru64'), but it
-probably isn't limited to that system.
+* The `configure' script doesn't find the jpeg library.
-You can configure the jpeg library with the `--enable-shared' option
-and then rebuild libjpeg. This produces a shared version of libjpeg,
-which you need to install. Finally, rerun the Emacs configure script,
-which should now find the jpeg library. Alternatively, modify the
-generated src/Makefile to link the .a file explicitly.
+There are reports that this happens on some systems because the linker
+by default only looks for shared libraries, but jpeg distribution by
+default only installs a nonshared version of the library, `libjpeg.a'.
-(If you need the static version of the jpeg library as well, configure
-libjpeg with both `--enable-static' and `--enable-shared' options.)
+If this is the problem, you can configure the jpeg library with the
+`--enable-shared' option and then rebuild libjpeg. This produces a
+shared version of libjpeg, which you need to install. Finally, rerun
+the Emacs configure script, which should now find the jpeg library.
+Alternatively, modify the generated src/Makefile to link the .a file
+explicitly, and edit src/config.h to define HAVE_JPEG.

+Emacs executable to fail with the above message.
In some of these cases, a time skew between the NFS server and the
machine where Emacs is built is detected and reported by GNU Make
The solution is to remove this line from `etc/fstab'.
+* Emacs binary is not in executable format, and cannot be run.
+
+This was reported to happen when Emacs is built in a directory mounted
+via NFS. Usually, the file `emacs' produced in these cases is full of
+binary null characters, and the `file' utility says:
+
+ emacs: ASCII text, with no line terminators
+
+We don't know what exactly causes this failure. A work-around is to
+build Emacs in a directory on a local disk.
+
* Accented ISO-8859-1 characters are displayed as | or _.
Try other font set sizes (S-mouse-1). If the problem persists with

libungif-4.1.0 are resolved by using version libungif-4.1.0b1.

+if a binary built against a shared libungif is run on a system with an
+older version.
-* Font Lock displays portions of the bufefr in incorrect faces.
+* Font Lock displays portions of the buffer in incorrect faces.
By far the most frequent cause of this is a parenthesis `(' or a brace
`{' in column zero. Font Lock assumes that such a paren is outside of

parens, and therefore this assumption is used to allow optimizations
in Font Lock's syntactical analysis. These optimizations avoid some

+pathological cases where jit-lock, the Just-in-Time fontification
introduced with Emacs 21.1, could significantly slow down scrolling
through the buffer, especially scrolling backwards, and also jumping
to the end of a very large buffer.
+Beginning with version 21.4, a parenthesis or a brace in column zero
+is highlighted in bold-red face if it is inside a string or a comment,
+to indicate that it could interfere with Font Lock (and also with
+indentation) and should be moved or escaped with a backslash.
+
If you don't use large buffers, or have a very fast machine which
makes the delays insignificant, you can avoid the incorrect
fontification by setting the variable
Another alternative is to avoid a paren in column zero. For example,
in a Lisp string you could precede the paren with a backslash.
+* When running on KDE, colors or fonts are not as specified for Emacs,
+or messed up.
+
+For example, you could see background you set for Emacs only in the
+empty portions of the Emacs display, while characters have some other
+background.
+
+This happens because KDE's defaults apply its color and font
+definitions even to applications that weren't compiled for KDE. The
+solution is to uncheck the "Apply fonts and colors to non-KDE apps"
+option in Preferences->Look&Feel->Style (KDE 2). In KDE 3, this option
+is in the "Colors" section, rather than "Style".
+
+Alternatively, if you do want the KDE defaults to apply to other
+applications, but not to Emacs, you could modify the file `Emacs.ad'
+(should be in the `/usr/share/apps/kdisplay/app-defaults/' directory)
+so that it doesn't set the default background and foreground only for
+Emacs. For example, make sure the following resources are either not
+present or commented out:
+
+ Emacs.default.attributeForeground
+ Emacs.default.attributeBackground
+ Emacs*Foreground
+ Emacs*Background
+
* Interrupting Cygwin port of Bash from Emacs doesn't work.
Cygwin 1.x builds of the ported Bash cannot be interrupted from the
keyboard interrupt event sent by Emacs to Bash. (Older Cygwin ports
of Bash, up to b20.1, did receive SIGINT from Emacs.)
+* Dired is very slow.
+
+This could happen if invocation of the `df' program takes a long
+time. Possible reasons for this include:
+
+ - ClearCase mounted filesystems (VOBs) that sometimes make `df'
+ response time extremely slow (dozens of seconds);
+
+ - slow automounters on some old versions of Unix;
+
+ - slow operation of some versions of `df'.
+
+To work around the problem, you could either (a) set the variable
+`directory-free-space-program' to nil, and thus prevent Emacs from
+invoking `df'; (b) use `df' from the GNU Fileutils package; or
+(c) use CVS, which is Free Software, instead of ClearCase.
+
* Accessing remote files with ange-ftp hangs the MS-Windows version of Emacs.
If the FTP client is the Cygwin port of GNU `ftp', this appears to be
The solution is to downgrade to an older version of the Cygwin DLL
(version 1.3.2 was reported to solve the problem), or use the stock
-Windows FTP client, usually found in the `C:\WINDOWS' directory. To
-force ange-ftp use the stock Windows client, set the variable
-`ange-ftp-ftp-program-name' to the absolute file name of the client's
-executable. For example:

are compiling with the system's `cc' and CFLAGS containing `-O5'. If
so, you have hit a compiler bug. Please make sure to re-configure
Emacs so that it isn't compiled with `-O5'.
-* The PSGML package uses the obsolete variables
+* Compiling on AIX 4.3.x or 4.4 fails.
+
+This could happen if you use /bin/c89 as your compiler, instead of
+the default `cc'. /bin/c89 treats certain warnings, such as benign
+redefinitions of macros, as errors, and fails the build. A solution
+is to use the default compiler `cc'.
+
+* Old versions of the PSGML package use the obsolete variables
`before-change-function' and `after-change-function', which are no
-longer used by Emacs. These changes to PSGML 1.2.2 fix that.

-* Unicode characters are not unified with other Mule charsets.
-
-As of v21.1, Emacs charsets are still not unified. This means that
-characters which belong to charsets such as Latin-2, Greek, Hebrew,
-etc. and the same characters in the `mule-unicode-*' charsets are
-different characters, as far as Emacs is concerned. For example, text
-which includes Unicode characters from the Latin-2 locale cannot be
-encoded by Emacs with ISO 8859-2 coding system; and if you yank Greek
-text from a buffer whose buffer-file-coding-system is greek-iso-8bit
-into a mule-unicode-0100-24ff buffer, Emacs won't be able to save that
-buffer neither as ISO 8859-7 nor as UTF-8.
-
-To work around this, install some add-on package such as Mule-UCS.
+longer used by Emacs. Please use PSGML 1.2.3 or later.
+
+* PSGML conflicts with sgml-mode.
+
+PSGML package uses the same names of some variables (like keymap)
+as built-in sgml-mode.el because it was created as a replacement
+of that package. The conflict will be shown if you load
+sgml-mode.el before psgml.el. E.g. this could happen if you edit
+HTML page and then start to work with SGML or XML file. html-mode
+(from sgml-mode.el) is used for HTML file and loading of psgml.el
+(for sgml-mode or xml-mode) will cause an error.

+
+It can fail to work with ldapsearch program from OpenLDAP version 1.
+Version 1 of OpenLDAP is now deprecated. If you are still using it,
+please upgrade to version 2. As a temporary workaround, remove
+argument "-x" from the variable `ldap-ldapsearch-args'.
* The `oc-unicode' package doesn't work with Emacs 21.
This package tries to define more private charsets than there are free
-slots now. If the built-in Unicode/UTF-8 support is insufficient,
-e.g. if you need more CJK coverage, use the current Mule-UCS package.

+flexible. (Use option `utf-translate-cjk-mode' if you need CJK
+support.) Files encoded as emacs-mule using oc-unicode aren't
+generally read correctly by Emacs 21.
* Using epop3.el package causes Emacs to signal an error.
for epop3 that fixes this, but perhaps a newer version of epop3
corrects that.
+* ps-print commands fail to find prologue files ps-prin*.ps.
+
+This can happen if you use an old version of X-Symbol package: it
+defines compatibility functions which trick ps-print into thinking it
+runs in XEmacs, and look for the prologue files in a wrong directory.
+
+The solution is to upgrade X-Symbol to a later version.
+
+* lpr commands don't work on MS-Windows with some cheap printers.
+
+This problem may also strike other platforms, but the solution is
+likely to be a global one, and not Emacs specific.
+
+Many cheap inkjet, and even some cheap laser printers, do not
+print plain text anymore, they will only print through graphical
+printer drivers. A workaround on MS-Windows is to use Windows' basic
+built in editor to print (this is possibly the only useful purpose it
+has):
+
+(setq printer-name "") ;; notepad takes the default
+(setq lpr-command "notepad") ;; notepad
+(setq lpr-switches nil) ;; not needed
+(setq lpr-printer-switch "/P") ;; run notepad as batch printer
+
* 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.
+Similar problems could prevent Emacs from building, since the build
+process invokes Emacs several times.
+
On many systems, it is possible to set LD_LIBRARY_PATH in your
environment to specify additional directories where shared libraries
can be found.
Emacs is linked. With LD_RUN_PATH set, the linker will include a
specified run-time search path in the executable.
+On some systems, Emacs can crash due to problems with dynamic
+linking. Specifically, on SGI Irix 6.5, crashes were reported with
+backtraces like this:
+
+ (dbx) where
+ 0 strcmp(0xf49239d, 0x4031184, 0x40302b4, 0x12, 0xf0000000, 0xf4923aa, 0x0, 0x492ddb2) ["/xlv22/ficus-jan23/work/irix/lib/libc/libc_n32_M3_ns/strings/strcmp.s":35, 0xfb7e480]

+(`rld' is the dynamic linker.) We don't know yet why this
+happens, but setting the environment variable LD_BIND_NOW to 1 (which
+forces the dynamic linker to bind all shared objects early on) seems
+to work around the problem.

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
Auto-compress mode it needs for this will not be loaded until later,
when your .emacs file is processed. (The package `fontset.el' is
required to set up fonts used to display text on window systems, and
-its loaded very early in the startup procedure.)
+it's loaded very early in the startup procedure.)
Similarly, any other .el file for which there's no corresponding .elc
file could fail to load if it is compressed.
The solution is to uncompress all .el files which don't have a .elc
file.
+Another possible reason for such failures is stale *.elc files
+lurking somewhere on your load-path. The following command will
+print any duplicate Lisp files that are present in load-path:
+
+ emacs -q -batch -f list-load-path-shadows
+
+If this command prints any file names, some of these files are stale,
+and should be deleted or their directories removed from your
+load-path.
+
+* Emacs prints an error at startup after upgrading from an earlier version.
+
+An example of such an error is:
+
+ x-complement-fontset-spec: "Wrong type argument: stringp, nil"
+
+This can be another symptom of stale *.elc files in your classpath.
+The following command will print any duplicate Lisp files that are
+present in load-path:
+
+ emacs -q -batch -f list-load-path-shadows
+
+If this command prints any file names, some of these files are stale,
+and should be deleted or their directories removed from your
+load-path.
+
* Attempting to visit remote files via ange-ftp fails.
If the error message is "ange-ftp-file-modtime: Specified time is not
representable", then this could happen when `lukemftp' is used as the
-ftp client. This was reported to happen on Debian GNU/Linux 2.4.3
