4 Emacs for Windows
5
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:
9
10 ftp://ftp.gnu.org/gnu/emacs/windows/
11
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.
15
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.
20
21 Answers to frequently asked questions, and further information about
22 this port of GNU Emacs and related software packages can be found via
23 http:

26
27 * Preliminaries
28
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-X, the rest of the subdirectories
33 are in the src distribution, which the barebin distribution is
34 designed to be used with.
35
36 * Setting up Emacs
37
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".
44
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.
48
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.
57
58 * Prerequisites for Windows 9X
59
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.)
68
69 * Starting Emacs
70
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.
77
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.
84
85 * EXE files included
86
87 Emacs comes with the following executable files in the bin directory.
88
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.
92
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.
97
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.
101
102 + emacsclientw.exe - A version of emacsclient that does not open
103 a command-line window.
104
105 + addpm.exe - A basic installer that creates Start Menu icons for Emacs.
106 Running this is optional.
107
108 + cmdproxy.exe - Used internally by Emacs to work around problems with
109 the native shells in various versions of Windows.
110
111 + ctags.exe, etags.exe - Tools for generating tag files. See the
112 `Tags' node of the Emacs manual.
113
114 + ebrowse.exe - A tool for generating C++ browse information. See the
115 `Ebrowse' manual.
116
117 + ddeclient.exe - A tool for interacting with DDE servers.
118
119 + hexl.exe - A tool for producing hex dumps of binary files. See the
120 `Editing Binary Files' node of the Emacs manual.
121
122 + movemail.exe - A helper application for safely moving mail from
123 a mail spool or POP server to a local user mailbox. See the
124 `Movemail' node of the Emacs manual.
125
126 * Image support
127
128 Emacs has built in support for XBM and PPM/PGM/PBM images, and the
129 libXpm library is bundled, providing XPM support (required for color
130 toolbar icons and splash screen). Source for libXpm should be available
131 on the same place as you got this binary distribution from.
132
133 Emacs can also support some other image formats with appropriate
134 libraries. These libraries are all available as part of GTK
135 download for Windows (http://www.gtk.org/download/win32.php), or
136 from the GnuWin32 project. Emacs will find them if the directory
137 they are installed in is on the PATH.
138
139 PNG: requires the PNG reference library 1.4 or later, which will
140 be named libpng14.dll or libpng14-14.dll. LibPNG requires zlib,
141 which should come from the same source as you got libpng.
142 Starting with Emacs 23.3, the precompiled Emacs binaries are
143 built with libpng 1.4.x and later, and are incompatible with
144 earlier versions of libpng DLLs. So if you have libpng 1.2.x,
145 the PNG support will not work, and you will have to download
146 newer versions.
147
148 JPEG: requires the Independent JPEG Group's libjpeg 6b or later,
149 which will be called jpeg62.dll, libjpeg.dll, jpeg-62.dll or jpeg.dll.
150
151 TIFF: requires libTIFF 3.0 or later, which will be called libtiff3.dll
152 or libtiff.dll.
153
154 GIF: requires libungif or giflib 4.1 or later, which will be
155 called giflib4.dll, libungif4.dll or libungif.dll.
156
157 If you have image support DLLs under different names, customize the
158 value of `dynamic-library-alist'.
159
160 In addition, Emacs can be compiled to support SVG. This precompiled
161 distribution has not been compiled that way, since the SVG library
162 or one or more of its extensive dependencies appear to be
163 unreliable under Windows. See nt/INSTALL in the src distribution if
164 you wish to compile Emacs with SVG support.
165
166 * GnuTLS support
167
168 In order to support GnuTLS at runtime, Emacs must be able to find
169 the relevant DLLs during startup; failure to do so is not an error,
170 but GnuTLS won't be available to the running session.
171
172 You can get pre-built binaries (including any required DLL and the
173 header files) at http://sourceforge.net/projects/ezwinports/files/.
174
175 * libxml2 support
176
177 In order to support libxml2 at runtime, a libxml2-enabled Emacs must
178 be able to find the relevant DLLs during startup; failure to do so
179 is not an error, but libxml2 features won't be available to the
180 running session.
181
182 You can get pre-built binaries (including any required DLL and the
183 header files) at http://sourceforge.net/projects/ezwinports/files/.
184
185 * Uninstalling Emacs
186
187 If you should need to uninstall Emacs, simply delete all the files
188 and subdirectories from the directory where it was unpacked (Emacs
189 does not install or update any files in system directories or
190 anywhere else). If you ran the addpm.exe program to create the
191 registry entries and the Start menu icon, then you can remove the
192 registry entries using regedit. All of the settings are written
193 under the Software\GNU\Emacs key in HKEY_LOCAL_MACHINE, or if you
194 didn't have administrator privileges when you installed, the same
195 key in HKEY_CURRENT_USER. Just delete the whole Software\GNU\Emacs
196 key.
197
198 The Start menu entry can be removed by right-clicking on the Task bar
199 and selecting Properties, then using the Remove option on the Start
200 Menu Programs page. (If you installed under an account with
201 administrator privileges, then you need to click the Advanced button
202 and look for the Gnu Emacs menu item under All Users.)
203
204 * Troubleshooting
205
206 Unpacking the distributions
207
208 If you encounter trouble trying to run Emacs, there are a number of
209 possible causes. Check the following for indications that the
210 distribution was not corrupted by the tools used to unpack it:
211
212 * Be sure to disable CR/LF translation or the executables will
213 be unusable. Older versions of WinZipNT would enable this
214 translation by default. If you are using WinZipNT, disable it.
215 (I don't have WinZipNT myself, and I do not know the specific
216 commands necessary to disable it.)
217
218 * Check that filenames were not truncated to 8.3. For example,
219 there should be a file lisp\abbrevlist.elc; if this has been
220 truncated to abbrevli.elc, your distribution has been corrupted
221 while unpacking and Emacs will not start.
222
223 * On Windows 9X, make sure you have the UNICOWS.DLL library either
224 in the same directory where you have emacs.exe or in the
225 directory where system-wide DLLs are kept.
226
227 If you believe you have unpacked the distributions correctly and are
228 still encountering problems, see the section on Further Information
229 below.
230
231 Virus scanners
232
233 Some virus scanners interfere with Emacs' use of subprocesses. If you
234 are unable to use subprocesses and you use Dr. Solomon's WinGuard or
235 McAfee's Vshield, turn off "Scan all files" (WinGuard) or "boot sector
236 scanning" (McAfee exclusion properties).
237
238 * Further information
239
240 If you have access to the World Wide Web, I would recommend pointing
241 your favorite web browser to the following document (if you haven't
242 already):
243
244 http://www.gnu.org/software/emacs/windows/
245
246 This document serves as an FAQ and a source for further information
247 about the Windows port and related software packages.
248
249 In addition to the FAQ, there is a mailing list for discussing issues
250 related to the Windows port of Emacs. For information about the
251 list, see this Web page:
252
253 http://lists.gnu.org/mailman/listinfo/help-emacs-windows
254
255 To ask questions on the mailing list, send email to
256 help-emacs-windows@gnu.org. (You don't need to subscribe for that.)
257 To subscribe to the list or unsubscribe from it, fill the form you
258 find at http://lists.gnu.org/mailman/listinfo/help-emacs-windows as
259 explained there.
260
261 Another valuable source of information and help which should not be
262 overlooked is the various Usenet news groups dedicated to Emacs.
263 These are particularly good for help with general issues which aren't
264 specific to the Windows port of Emacs. The main news groups to use
265 for seeking help are:
266
267 gnu.emacs.help
268 comp.emacs
269
270 There are also fairly regular postings and announcements of new or
271 updated Emacs packages on this group:
272
273 gnu.emacs.sources
274
275 * Reporting bugs
276
277 If you encounter a bug in this port of Emacs, we would like to hear
278 about it. First check the FAQ on the web page above to see if the bug
279 is already known and if there are any workarounds. Then check whether
280 the bug has something to do with code in your .emacs file, e.g. by
281 invoking Emacs with the "-Q" option.
282
283 If you decide that it is a bug in Emacs, use the built in bug
284 reporting facility to report it (from the menu; Help -> Send Bug Report).
285 If you have not yet configured Emacs for mail, then when you press
286 C-c C-c to send the report, it will ask you to paste the text of the
287 report into your mail client. If the bug is related to subprocesses,
288 also specify which shell you are using (e.g., include the values of
289 `shell-file-name' and `explicit-shell-file-name' in your message).
290
