Emacs for Windows
This README file describes how to set up and run a precompiled
version of GNU Emacs for Windows. This distribution can be found on
the ftp.gnu.org server and its mirrors:
ftp://ftp.gnu.org/gnu/emacs/windows/
This server contains other distributions, including the full Emacs
source distribution and a barebin distribution which can be installed
over it, as well as older releases of Emacs for Windows.
Answers to frequently asked questions, and further information about
this port of GNU Emacs and related software packages can be found via
http:
http://www.gnu.org/software/emacs/windows/
* Preliminaries
Along with this file should be six subdirectories (bin, etc, info,
lisp, leim, site-lisp). If you have downloaded the barebin
distribution, then it will contain only the bin directory and the
built in documentation in etc/DOC-X, the rest of the subdirectories
are in the src distribution, which the barebin distribution is
designed to be used with.
* Setting up Emacs
To install Emacs, simply unpack all the files into a directory of
your choice, but note that you might encounter minor problems if
there is a space anywhere in the directory name. To complete the
installation process, you can optionally run the program addpm.exe
in the bin subdirectory. This will put an icon for Emacs in the
Start Menu under "Start -> Programs -> Gnu Emacs".
Some users have reported that the Start Menu item is not created for
them. If this happens, just create your own shortcut to runemacs.exe,
eg. by dragging it on to the desktop or the Start button.
Note that running addpm is now an optional step; Emacs is able to
locate all of its files without needing any information to be set in
the environment or the registry, although such settings will still
be obeyed if present. This is convenient for running Emacs on a
machine which disallows registry changes, or on which software
should not be installed. For instance, you can now run Emacs
directly from a CD or USB flash drive without copying or installing
anything on the machine itself.
* Starting Emacs
To run Emacs, simply select Emacs from the Start Menu, or invoke
runemacs.exe directly from Explorer or from a command prompt. This
will start Emacs in its default GUI mode, ready to use. If you have
never used Emacs before, you should follow the tutorial at this
point (select Emacs Tutorial from the Help menu), since Emacs is
quite different from ordinary Windows applications in many respects.
If you want to use Emacs in tty or character mode within a command
window, you can start it by typing "emacs -nw" at the command prompt.
(Obviously, you need to ensure that the Emacs bin subdirectory is in
your PATH first, or specify the path to emacs.exe.) The -nw
(non-windowed) mode of operation is most useful if you have a telnet
server on your machine, allowing you to run Emacs remotely.
* EXE files included
Emacs comes with the following executable files in the bin directory.
+ emacs.exe - The main Emacs executable. As this is designed to run
as both a text-mode application (emacs -nw) and as a GUI application,
it will pop up a command prompt window if run directly from Explorer.
+ runemacs.exe - A wrapper for running Emacs as a GUI application
without popping up a command prompt window.
+ emacsclient.exe - A command-line client program that can
communicate with a running Emacs process. See the `Emacs Server'
node of the Emacs manual.
+ emacsclientw.exe - A version of emacsclient that does not open
a command-line window.
+ addpm.exe - A basic installer that creates Start Menu icons for Emacs.
Running this is optional.
+ cmdproxy.exe - Used internally by Emacs to work around problems with
the native shells in various versions of Windows.
+ ctags.exe, etags.exe - Tools for generating tag files. See the
`Tags' node of the Emacs manual.
+ ebrowse.exe - A tool for generating C++ browse information. See the
`Ebrowse' manual.
+ ddeclient.exe - A tool for interacting with DDE servers.
+ hexl.exe - A tool for converting files to hex dumps. See the
`Editing Binary Files' node of the Emacs manual.
+ movemail.exe - A helper application for safely moving mail from
a mail spool or POP server to a local user mailbox. See the
`Movemail' node of the Emacs manual.
* Image support
Emacs has built in support for XBM and PPM/PGM/PBM images, and the
libXpm library is bundled, providing XPM support (required for color
toolbar icons and splash screen). Source for libXpm should be available
on the same place as you got this binary distribution from. The version
of libXpm bundled with this version of Emacs is 3.5.7, based on x.org's
libXpm library from X11R7.3.
Emacs can also support some other image formats with appropriate
libraries. These libraries are all available as part of GTK
download for Windows (http://www.gtk.org/download-windows.html), or
from the GnuWin32 project. Emacs will find them if the directory
they are installed in is on the PATH.
PNG: requires the PNG reference library 1.4 or later, which will
be named libpng14.dll or libpng14-14.dll. LibPNG requires zlib,
which should come from the same source as you got libpng.
Starting with Emacs 23.3, the precompiled Emacs binaries are
built with libpng 1.4.x and later, and are incompatible with
earlier versions of libpng DLLs. So if you have libpng 1.2.x,
the PNG support will not work, and you will have to download
newer versions.
JPEG: requires the Independant JPEG Group's libjpeg 6b or later,
which will be called jpeg62.dll, libjpeg.dll, jpeg-62.dll or jpeg.dll.
TIFF: requires libTIFF 3.0 or later, which will be called libtiff3.dll
or libtiff.dll.
GIF: requires libungif or giflib 4.1 or later, which will be
called giflib4.dll, libungif4.dll or libungif.dll.
If you have image support DLLs under different names, customize the
value of `dynamic-library-alist'.
In addition, Emacs can be compiled to support SVG. This precompiled
distribution has not been compiled that way, since the SVG library
or one or more of its extensive dependencies appear to be
unreliable under Windows. See nt/INSTALL in the src distribution if
you wish to compile Emacs with SVG support.
* Uninstalling Emacs
If you should need to uninstall Emacs, simply delete all the files
and subdirectories from the directory where it was unpacked (Emacs
does not install or update any files in system directories or
anywhere else). If you ran the addpm.exe program to create the
registry entries and the Start menu icon, then you can remove the
registry entries using regedit. All of the settings are written
under the Software\GNU\Emacs key in HKEY_LOCAL_MACHINE, or if you
didn't have administrator privileges when you installed, the same
key in HKEY_CURRENT_USER. Just delete the whole Software\GNU\Emacs
key.
The Start menu entry can be removed by right-clicking on the Task bar
and selecting Properties, then using the Remove option on the Start
Menu Programs page. (If you installed under an account with
administrator privileges, then you need to click the Advanced button
and look for the Gnu Emacs menu item under All Users.)
* Troubleshooting
Unpacking the distributions
If you encounter trouble trying to run Emacs, there are a number of
possible causes. Check the following for indications that the
distribution was not corrupted by the tools used to unpack it:
* Be sure to disable CR/LF translation or the executables will
be unusable. Older versions of WinZipNT would enable this
translation by default. If you are using WinZipNT, disable it.
(I don't have WinZipNT myself, and I do not know the specific
commands necessary to disable it.)
* Check that filenames were not truncated to 8.3. For example,
there should be a file lisp\abbrevlist.elc; if this has been
truncated to abbrevli.elc, your distribution has been corrupted
while unpacking and Emacs will not start.
If you believe you have unpacked the distributions correctly and are
still encountering problems, see the section on Further Information
below.
Virus scanners
Some virus scanners interfere with Emacs' use of subprocesses. If you
are unable to use subprocesses and you use Dr. Solomon's WinGuard or
McAfee's Vshield, turn off "Scan all files" (WinGuard) or "boot sector
scanning" (McAfee exclusion properties).
* Further information
If you have access to the World Wide Web, I would recommend pointing
your favorite web browser to the following document (if you haven't
already):
http://www.gnu.org/software/emacs/windows/
This document serves as an FAQ and a source for further information
about the Windows port and related software packages.
In addition to the FAQ, there is a mailing list for discussing issues
related to the Windows port of Emacs. For information about the
list, see this Web page:
http://lists.gnu.org/mailman/listinfo/help-emacs-windows
To ask questions on the mailing list, send email to
help-emacs-windows@gnu.org. (You don't need to subscribe for that.)
To subscribe to the list or unsubscribe from it, fill the form you
find at http://lists.gnu.org/mailman/listinfo/help-emacs-windows as
explained there.
Another valuable source of information and help which should not be
overlooked is the various Usenet news groups dedicated to Emacs.
These are particularly good for help with general issues which aren't
specific to the Windows port of Emacs. The main news groups to use
for seeking help are:
gnu.emacs.help
comp.emacs
There are also fairly regular postings and announcements of new or
updated Emacs packages on this group:
gnu.emacs.sources
* Reporting bugs
If you encounter a bug in this port of Emacs, we would like to hear
about it. First check the FAQ on the web page above to see if the bug
is already known and if there are any workarounds. Then check whether
the bug has something to do with code in your .emacs file, e.g. by
invoking Emacs with the "-Q" option.
If you decide that it is a bug in Emacs, use the built in bug
reporting facility to report it (from the menu; Help -> Send Bug Report).
If you have not yet configured Emacs for mail, then when you press
C-c C-c to send the report, it will ask you to paste the text of the
report into your mail client. If the bug is related to subprocesses,
also specify which shell you are using (e.g., include the values of
`shell-file-name' and `explicit-shell-file-name' in your message).
Enjoy!
