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, as well as older releases of Emacs for Windows.
15 Information on how to compile Emacs from sources on Windows is in
16 the files README and INSTALL in the nt/ sub-directory of the
17 top-level Emacs directory in the source distribution. If you
18 received this file as part of the Emacs source distribution, and are
19 looking for information on how to build Emacs on MS-Windows, please
20 read those 2 files and not this one.
24 Along with this file should be four subdirectories (bin, libexec,
29 To install Emacs, simply unpack all the files into a directory of
30 your choice. To complete the installation process, you can
31 optionally run the program addpm.exe in the bin subdirectory. This
32 will put an icon for Emacs in the Start Menu under
33 "Start -> Programs -> Gnu Emacs".
35 Some users have reported that the Start Menu item is not created for
36 them. If this happens, just create your own shortcut to runemacs.exe,
37 eg. by dragging it on to the desktop or the Start button.
39 Note that running addpm is now an optional step; Emacs is able to
40 locate all of its files without needing any information to be set in
41 the environment or the registry, although such settings will still
42 be obeyed if present. This is convenient for running Emacs on a
43 machine which disallows registry changes, or on which software
44 should not be installed. For instance, you can now run Emacs
45 directly from a CD or USB flash drive without copying or installing
46 anything on the machine itself.
48 * Prerequisites for Windows 9X
50 To run Emacs on Windows 9X (Windows 95/98/Me), you will need to have
51 the Microsoft Layer for Unicode (MSLU) installed. It can be
52 downloaded from the Microsoft site, and comes in a form of a single
53 dynamic library called UNICOWS.DLL. If this library is not
54 accessible to Emacs, it will pop up a dialog saying that it cannot
55 find the library, and will refuse to start up.
59 To run Emacs, simply select Emacs from the Start Menu, or invoke
60 runemacs.exe directly from Explorer or from a command prompt. This
61 will start Emacs in its default GUI mode, ready to use. If you have
62 never used Emacs before, you should follow the tutorial at this
63 point (select Emacs Tutorial from the Help menu), since Emacs is
64 quite different from ordinary Windows applications in many respects.
66 If you want to use Emacs in tty or character mode within a command
67 window, you can start it by typing "emacs -nw" at the command prompt.
68 (Obviously, you need to ensure that the Emacs bin subdirectory is in
69 your PATH first, or specify the path to emacs.exe.) The -nw
70 (non-windowed) mode of operation is most useful if you have a telnet
71 server on your machine, allowing you to run Emacs remotely.
75 Emacs comes with the following executable files in the bin directory.
77 + emacs.exe - The main Emacs executable. As this is designed to run
78 as both a text-mode application (emacs -nw) and as a GUI application,
79 it will pop up a command prompt window if run directly from Explorer.
81 + runemacs.exe - A wrapper for running Emacs as a GUI application
82 without popping up a command prompt window. If you create a
83 desktop shortcut for invoking Emacs, make it point to this
84 executable, not to emacs.exe.
86 + emacsclient.exe - A command-line client program that can
87 communicate with a running Emacs process. See the `Emacs Server'
88 node of the Emacs manual.
90 + emacsclientw.exe - A version of emacsclient that does not open
91 a command-line window.
93 + addpm.exe - A basic installer that creates Start Menu icons for Emacs.
94 Running this is optional.
96 + ctags.exe, etags.exe - Tools for generating tag files. See the
97 `Tags' node of the Emacs manual.
99 + ebrowse.exe - A tool for generating C++ browse information. See the
102 Several helper programs are in a version-specific subdirectory of
103 the libexec directory:
105 + cmdproxy.exe - Used internally by Emacs to work around problems with
106 the native shells in various versions of Windows.
108 + ddeclient.exe - A tool for interacting with DDE servers. To be
109 invoked as "ddeclient SERVER [TOPIC]", where SERVER is the DDE
110 server name, and sends each line of its standard input to the DDE
111 server using the DdeClientTransaction API. This program is
112 supposed to be invoked via the 'call-process-region' Emacs
115 + hexl.exe - A tool for producing hex dumps of binary files. See the
116 `Editing Binary Files' node of the Emacs manual.
118 + movemail.exe - A helper application for safely moving mail from
119 a mail spool or POP server to a local user mailbox. See the
120 `Movemail' node of the Emacs manual.
122 + profile.exe - A helper program that generates periodic events for
123 profiling Emacs Lisp code.
125 + update-game-score.exe - A utility for updating the score files of
130 Emacs has built in support for XBM and PPM/PGM/PBM images, and the
131 libXpm library is bundled, providing XPM support (required for color
132 toolbar icons and splash screen). Source for libXpm should be available
133 from the same place from which you got this binary distribution.
135 Emacs can also support some other image formats with appropriate
136 libraries. These libraries are all available on the following sites:
138 1. http://sourceforge.net/projects/ezwinports/files/
139 -- leaner, more up-to-date builds, only for 32-bit Emacs
140 2. http://www.gtk.org/download/win32.php
141 http://www.gtk.org/download/win64.php
142 -- the GTK project site; offers much fatter builds, but includes
143 64-bit DLLs (from the 2nd URL)
144 3. GnuWin32 project -- very old builds, not recommended
146 The libraries to download are mentioned below. Some libraries
147 depend on others that need to be downloaded separately from the same
148 site; please consult the download instructions on each site for the
149 details. In general, the ezwinports site mentioned above has all
150 the dependencies bundled in the same zip archive, so installing from
151 there is the easiest.
153 Emacs will find these libraries if the directory they are installed
154 in is on the PATH or in the same directory where you have emacs.exe.
155 Here are some specific comments about each image type:
157 PNG: requires the PNG reference library 1.4 or later, which will
158 be named libpngNN.dll or libpngNN-NN.dll. LibPNG requires zlib,
159 which should come from the same source as you got libpng.
160 Starting with Emacs 23.3, the precompiled Emacs binaries are
161 built with libpng 1.4.x and later, and are incompatible with
162 earlier versions of libpng DLLs. So if you have libpng 1.2.x,
163 the PNG support will not work, and you will have to download
166 JPEG: requires the Independent JPEG Group's libjpeg 6b or later,
167 which will be called jpeg62.dll, libjpeg.dll, jpeg-62.dll or jpeg.dll.
169 TIFF: requires libTIFF 3.0 or later, which will be called libtiffN.dll
170 or libtiff-N.dll or libtiff.dll.
172 GIF: requires libungif or giflib 4.1 or later, which will be
173 called libgif-6.dll, giflib4.dll, libungif4.dll or libungif.dll.
175 SVG: requires librsvg 2.x whose DLL will be called
176 librsvg-2-2.dll. SVG also requires several dependency DLLs,
177 such as Pango, Cairo, and Glib, all of them found on the
178 above-mentioned sites. If you download from the ezwinports
179 site, you need only librsvg-2.nn.mm-x-w32-bin.zip, it comes with
180 all the other dependencies bundled.
182 If you have image support DLLs under different names, customize the
183 value of `dynamic-library-alist'.
187 GnuTLS provides SSL/TLS network support for Emacs (https, imaps and
190 In order to support GnuTLS at runtime, Emacs must be able to find
191 the relevant DLLs during startup; failure to do so is not an error,
192 but GnuTLS won't be available to the running session.
194 You can get pre-built binaries (including any dependency DLLs) at
195 http://sourceforge.net/projects/ezwinports/files/.
199 libxml2 provides HTML parsing support for Emacs, which is necessary
200 to use the built-in eww browser.
202 In order to support libxml2 at runtime, a libxml2-enabled Emacs must
203 be able to find the relevant DLLs during startup; failure to do so
204 is not an error, but libxml2 features won't be available to the
207 You can get pre-built binaries (including any required DLL and the
208 header files) at http://sourceforge.net/projects/ezwinports/files/.
212 If you should need to uninstall Emacs, simply delete all the files
213 and subdirectories from the directory where it was unpacked (Emacs
214 does not install or update any files in system directories or
215 anywhere else). If you ran the addpm.exe program to create the
216 registry entries and the Start menu icon, then you can remove the
217 registry entries using regedit. All of the settings are written
218 under the Software\GNU\Emacs key in HKEY_LOCAL_MACHINE, or if you
219 didn't have administrator privileges when you installed, the same
220 key in HKEY_CURRENT_USER. Just delete the whole Software\GNU\Emacs
223 The Start menu entry can be removed by right-clicking on the Task bar
224 and selecting Properties, then using the Remove option on the Start
225 Menu Programs page. (If you installed under an account with
226 administrator privileges, then you need to click the Advanced button
227 and look for the Gnu Emacs menu item under All Users.)
231 Unpacking the distributions
233 If you encounter trouble trying to run Emacs, there are a number of
234 possible causes. Check the following for indications that the
235 distribution was not corrupted by the tools used to unpack it:
237 * Be sure to disable CR/LF translation or the executables will
238 be unusable. Older versions of WinZipNT would enable this
239 translation by default. If you are using WinZipNT, disable it.
240 (I don't have WinZipNT myself, and I do not know the specific
241 commands necessary to disable it.)
243 * Check that filenames were not truncated to 8.3. For example,
244 there should be a file lisp\abbrevlist.elc; if this has been
245 truncated to abbrevli.elc, your distribution has been corrupted
246 while unpacking and Emacs will not start.
248 * On Windows 9X, make sure you have the UNICOWS.DLL library either
249 in the same directory where you have emacs.exe or in the
250 directory where system-wide DLLs are kept.
252 If you believe you have unpacked the distributions correctly and are
253 still encountering problems, see the section on Further Information
258 Some virus scanners interfere with Emacs' use of subprocesses. If you
259 are unable to use subprocesses and you use Dr. Solomon's WinGuard or
260 McAfee's Vshield, turn off "Scan all files" (WinGuard) or "boot sector
261 scanning" (McAfee exclusion properties).
263 * Further information
265 The FAQ for the MS Windows port of Emacs is distributed with Emacs
266 (info manual "efaq-w32"), and also available at
268 http://www.gnu.org/software/emacs/manual/efaq-w32.html
270 In addition to the FAQ, there is a mailing list for discussing issues
271 related to the Windows port of Emacs. For information about the
272 list, see this Web page:
274 http://lists.gnu.org/mailman/listinfo/help-emacs-windows
276 To ask questions on the mailing list, send email to
277 help-emacs-windows@gnu.org. (You don't need to subscribe for that.)
278 To subscribe to the list or unsubscribe from it, fill the form you
279 find at http://lists.gnu.org/mailman/listinfo/help-emacs-windows as
282 Another valuable source of information and help which should not be
283 overlooked is the various Usenet news groups dedicated to Emacs.
284 These are particularly good for help with general issues which aren't
285 specific to the Windows port of Emacs. The main news groups to use
286 for seeking help are:
291 There are also fairly regular postings and announcements of new or
292 updated Emacs packages on this group:
298 If you encounter a bug in this port of Emacs, we would like to hear
299 about it. First check the FAQ on the web page above to see if the bug
300 is already known and if there are any workarounds. Then check whether
301 the bug has something to do with code in your .emacs file, e.g. by
302 invoking Emacs with the "-Q" option.
304 If you decide that it is a bug in Emacs, use the built in bug
305 reporting facility to report it (from the menu; Help -> Send Bug Report).
306 If you have not yet configured Emacs for mail, then when you press
307 C-c C-c to send the report, it will ask you to paste the text of the
308 report into your mail client. If the bug is related to subprocesses,
309 also specify which shell you are using (e.g., include the values of
310 `shell-file-name' and `explicit-shell-file-name' in your message).
