6 This README.W32 file describes how to set up and run a precompiled
7 distribution of GNU Emacs for Windows. You can find the precompiled
8 distribution on the ftp.gnu.org server and its mirrors:
10 ftp://ftp.gnu.org/gnu/emacs/windows/
12 This server contains other distributions, including the full Emacs
13 source distribution and a barebin distribution which can be installed
14 over it, as well as older releases of Emacs for Windows.
16 Information on how to compile Emacs from sources on Windows is in
17 the files README and INSTALL in this directory. If you received
18 this file as part of the Emacs source distribution, please read
19 those 2 files and not this one.
21 Answers to frequently asked questions, and further information about
22 this port of GNU Emacs and related software packages can be found via
25 http://www.gnu.org/software/emacs/windows/
29 Along with this file should be six subdirectories (bin, etc, info,
30 lisp, leim, site-lisp). If you have downloaded the barebin
31 distribution, then it will contain only the bin directory and the
32 built in documentation in etc/DOC, the rest of the subdirectories
33 are in the src distribution, which the barebin distribution is
34 designed to be used with.
38 To install Emacs, simply unpack all the files into a directory of
39 your choice, but note that you might encounter minor problems if
40 there is a space anywhere in the directory name. To complete the
41 installation process, you can optionally run the program addpm.exe
42 in the bin subdirectory. This will put an icon for Emacs in the
43 Start Menu under "Start -> Programs -> Gnu Emacs".
45 Some users have reported that the Start Menu item is not created for
46 them. If this happens, just create your own shortcut to runemacs.exe,
47 eg. by dragging it on to the desktop or the Start button.
49 Note that running addpm is now an optional step; Emacs is able to
50 locate all of its files without needing any information to be set in
51 the environment or the registry, although such settings will still
52 be obeyed if present. This is convenient for running Emacs on a
53 machine which disallows registry changes, or on which software
54 should not be installed. For instance, you can now run Emacs
55 directly from a CD or USB flash drive without copying or installing
56 anything on the machine itself.
58 * Prerequisites for Windows 9X
60 To run Emacs on Windows 9X (Windows 95/98/Me), you will need to have
61 the Microsoft Layer for Unicode (MSLU) installed. It can be
62 downloaded from the Microsoft site, and comes in a form of a single
63 dynamic library called UNICOWS.DLL. If this library is not
64 accessible to Emacs, it will pop up a dialog saying that it cannot
65 find the library, and will refuse to start up a GUI session.
66 (However, it is still possible to use Emacs in text mode, even
67 without UNICOWS.DLL, by invoking it as "emacs -nw", see below.)
71 To run Emacs, simply select Emacs from the Start Menu, or invoke
72 runemacs.exe directly from Explorer or from a command prompt. This
73 will start Emacs in its default GUI mode, ready to use. If you have
74 never used Emacs before, you should follow the tutorial at this
75 point (select Emacs Tutorial from the Help menu), since Emacs is
76 quite different from ordinary Windows applications in many respects.
78 If you want to use Emacs in tty or character mode within a command
79 window, you can start it by typing "emacs -nw" at the command prompt.
80 (Obviously, you need to ensure that the Emacs bin subdirectory is in
81 your PATH first, or specify the path to emacs.exe.) The -nw
82 (non-windowed) mode of operation is most useful if you have a telnet
83 server on your machine, allowing you to run Emacs remotely.
87 Emacs comes with the following executable files in the bin directory.
89 + emacs.exe - The main Emacs executable. As this is designed to run
90 as both a text-mode application (emacs -nw) and as a GUI application,
91 it will pop up a command prompt window if run directly from Explorer.
93 + runemacs.exe - A wrapper for running Emacs as a GUI application
94 without popping up a command prompt window. If you create a
95 desktop shortcut for invoking Emacs, make it point to this
96 executable, not to emacs.exe.
98 + emacsclient.exe - A command-line client program that can
99 communicate with a running Emacs process. See the `Emacs Server'
100 node of the Emacs manual.
102 + emacsclientw.exe - A version of emacsclient that does not open
103 a command-line window.
105 + addpm.exe - A basic installer that creates Start Menu icons for Emacs.
106 Running this is optional.
108 + cmdproxy.exe - Used internally by Emacs to work around problems with
109 the native shells in various versions of Windows.
111 + ctags.exe, etags.exe - Tools for generating tag files. See the
112 `Tags' node of the Emacs manual.
114 + ebrowse.exe - A tool for generating C++ browse information. See the
117 + ddeclient.exe - A tool for interacting with DDE servers. To be
118 invoked as "ddeclient SERVER [TOPIC]", where SERVER is the DDE
119 server name, and sends each line of its standard input to the DDE
120 server using the DdeClientTransaction API. This program is
121 supposed to be invoked via the 'call-process-region' Emacs
124 + hexl.exe - A tool for producing hex dumps of binary files. See the
125 `Editing Binary Files' node of the Emacs manual.
127 + movemail.exe - A helper application for safely moving mail from
128 a mail spool or POP server to a local user mailbox. See the
129 `Movemail' node of the Emacs manual.
133 Emacs has built in support for XBM and PPM/PGM/PBM images, and the
134 libXpm library is bundled, providing XPM support (required for color
135 toolbar icons and splash screen). Source for libXpm should be available
136 on the same place as you got this binary distribution from.
138 Emacs can also support some other image formats with appropriate
139 libraries. These libraries are all available as part of GTK
140 download for Windows (http://www.gtk.org/download/win32.php), or
141 from the GnuWin32 project. Emacs will find them if the directory
142 they are installed in is on the PATH.
144 PNG: requires the PNG reference library 1.4 or later, which will
145 be named libpng14.dll or libpng14-14.dll. LibPNG requires zlib,
146 which should come from the same source as you got libpng.
147 Starting with Emacs 23.3, the precompiled Emacs binaries are
148 built with libpng 1.4.x and later, and are incompatible with
149 earlier versions of libpng DLLs. So if you have libpng 1.2.x,
150 the PNG support will not work, and you will have to download
153 JPEG: requires the Independent JPEG Group's libjpeg 6b or later,
154 which will be called jpeg62.dll, libjpeg.dll, jpeg-62.dll or jpeg.dll.
156 TIFF: requires libTIFF 3.0 or later, which will be called libtiff3.dll
159 GIF: requires libungif or giflib 4.1 or later, which will be
160 called giflib4.dll, libungif4.dll or libungif.dll.
162 If you have image support DLLs under different names, customize the
163 value of `dynamic-library-alist'.
165 In addition, Emacs can be compiled to support SVG. This precompiled
166 distribution has not been compiled that way, since the SVG library
167 or one or more of its extensive dependencies appear to be
168 unreliable under Windows. See nt/INSTALL in the src distribution if
169 you wish to compile Emacs with SVG support.
173 In order to support GnuTLS at runtime, Emacs must be able to find
174 the relevant DLLs during startup; failure to do so is not an error,
175 but GnuTLS won't be available to the running session.
177 You can get pre-built binaries (including any required DLL and the
178 header files) at http://sourceforge.net/projects/ezwinports/files/.
182 In order to support libxml2 at runtime, a libxml2-enabled Emacs must
183 be able to find the relevant DLLs during startup; failure to do so
184 is not an error, but libxml2 features won't be available to the
187 You can get pre-built binaries (including any required DLL and the
188 header files) at http://sourceforge.net/projects/ezwinports/files/.
192 If you should need to uninstall Emacs, simply delete all the files
193 and subdirectories from the directory where it was unpacked (Emacs
194 does not install or update any files in system directories or
195 anywhere else). If you ran the addpm.exe program to create the
196 registry entries and the Start menu icon, then you can remove the
197 registry entries using regedit. All of the settings are written
198 under the Software\GNU\Emacs key in HKEY_LOCAL_MACHINE, or if you
199 didn't have administrator privileges when you installed, the same
200 key in HKEY_CURRENT_USER. Just delete the whole Software\GNU\Emacs
203 The Start menu entry can be removed by right-clicking on the Task bar
204 and selecting Properties, then using the Remove option on the Start
205 Menu Programs page. (If you installed under an account with
206 administrator privileges, then you need to click the Advanced button
207 and look for the Gnu Emacs menu item under All Users.)
211 Unpacking the distributions
213 If you encounter trouble trying to run Emacs, there are a number of
214 possible causes. Check the following for indications that the
215 distribution was not corrupted by the tools used to unpack it:
217 * Be sure to disable CR/LF translation or the executables will
218 be unusable. Older versions of WinZipNT would enable this
219 translation by default. If you are using WinZipNT, disable it.
220 (I don't have WinZipNT myself, and I do not know the specific
221 commands necessary to disable it.)
223 * Check that filenames were not truncated to 8.3. For example,
224 there should be a file lisp\abbrevlist.elc; if this has been
225 truncated to abbrevli.elc, your distribution has been corrupted
226 while unpacking and Emacs will not start.
228 * On Windows 9X, make sure you have the UNICOWS.DLL library either
229 in the same directory where you have emacs.exe or in the
230 directory where system-wide DLLs are kept.
232 If you believe you have unpacked the distributions correctly and are
233 still encountering problems, see the section on Further Information
238 Some virus scanners interfere with Emacs' use of subprocesses. If you
239 are unable to use subprocesses and you use Dr. Solomon's WinGuard or
240 McAfee's Vshield, turn off "Scan all files" (WinGuard) or "boot sector
241 scanning" (McAfee exclusion properties).
243 * Further information
245 If you have access to the World Wide Web, I would recommend pointing
246 your favorite web browser to the following document (if you haven't
249 http://www.gnu.org/software/emacs/windows/
251 This document serves as an FAQ and a source for further information
252 about the Windows port and related software packages.
254 In addition to the FAQ, there is a mailing list for discussing issues
255 related to the Windows port of Emacs. For information about the
256 list, see this Web page:
258 http://lists.gnu.org/mailman/listinfo/help-emacs-windows
260 To ask questions on the mailing list, send email to
261 help-emacs-windows@gnu.org. (You don't need to subscribe for that.)
262 To subscribe to the list or unsubscribe from it, fill the form you
263 find at http://lists.gnu.org/mailman/listinfo/help-emacs-windows as
266 Another valuable source of information and help which should not be
267 overlooked is the various Usenet news groups dedicated to Emacs.
268 These are particularly good for help with general issues which aren't
269 specific to the Windows port of Emacs. The main news groups to use
270 for seeking help are:
275 There are also fairly regular postings and announcements of new or
276 updated Emacs packages on this group:
282 If you encounter a bug in this port of Emacs, we would like to hear
283 about it. First check the FAQ on the web page above to see if the bug
284 is already known and if there are any workarounds. Then check whether
285 the bug has something to do with code in your .emacs file, e.g. by
286 invoking Emacs with the "-Q" option.
288 If you decide that it is a bug in Emacs, use the built in bug
289 reporting facility to report it (from the menu; Help -> Send Bug Report).
290 If you have not yet configured Emacs for mail, then when you press
291 C-c C-c to send the report, it will ask you to paste the text of the
292 report into your mail client. If the bug is related to subprocesses,
293 also specify which shell you are using (e.g., include the values of
294 `shell-file-name' and `explicit-shell-file-name' in your message).
