Emacs version 27.0.50 for MS-Windows This README file describes how to set up and run a precompiled distribution of the latest version of GNU Emacs for MS-Windows. You can find the precompiled distribution on the ftp.gnu.org server and its mirrors: https://ftp.gnu.org/gnu/emacs/windows/ This server contains other distributions, including the full Emacs source distribution, as well as older releases of Emacs for Windows. Information on how to compile Emacs from sources on Windows is in the files README and INSTALL in the nt/ sub-directory of the top-level Emacs directory in the source distribution, as is this file under the name README.W32. If you received this file as part of the Emacs source distribution, and are looking for information on how to build Emacs on MS-Windows, please read those 2 files and not this one. * Preliminaries There are two binary distributions named emacs-VER-x86_64-w64-mingw32.zip and emacs-VER-i686-w64-mingw32.zip, where VER is the Emacs version. These are 64-bit and 32-bit builds, respectively. If you are running a 32-bit version of MS-Windows, you need to install the 32-bit build; users of 64-bit Windows can use either build, but we recommend to install the 64-bit one, as it will be able to edit larger buffers and will generally run faster. The binary distribution has these top-level directories: + bin + libexec + share + var * Setting up Emacs To install Emacs, simply unpack the binary package into a directory of your choice. If you use the Windows Explorer and its "Extract" action, by default this will be in a top-level directory with the same name as the zip file. We also provide a set of optional dependencies, in emacs-MVER-x86_64-deps.zip or emacs-MVER-i686-deps.zip respectively, where MVER is the major Emacs version that should use these libraries. These provide Emacs with a number of additional optional capabilities, described in detail below. To use these, unpack them directly over the emacs directory structure. Note that, if extracting with the Windows Explorer, you will have to override the directory where it wants to put the file with the same directory where you extracted the Emacs binary package. Finally, and also optionally, you can run the program addpm.exe in the bin subdirectory which will place an icon for Emacs on the start page. (This is no longer needed in latest versions of Emacs, so we recommend you not do that, as running addpm.exe will insert entries into the Registry which might get in the way if you upgrade to later versions without updating those entries, or would like to uninstall Emacs.) Emacs is completely portable. You can create your own shortcut to runemacs.exe and place this wherever you find it convenient (the desktop and/or the Taskbar), or run it from a USB or network drive without copying or installing anything on the machine itself. * Prerequisites for Windows 9X The 32-bit build supports MS-Windows 9X (Windows 95/98/Me). To run Emacs on these versions of Windows, you will need to have the Microsoft Layer for Unicode (MSLU) installed. It can be downloaded from the Microsoft site, and comes in a form of a single dynamic library called UNICOWS.DLL. If this library is not accessible to Emacs on Windows 9X, it will pop up a dialog saying that it cannot find the UNICOWS library, and will refuse to start up. * 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. If you create a desktop shortcut for invoking Emacs, make it point to this executable, not to emacs.exe. If you pin Emacs to the task bar, edit the properties of the pinned shortcut (with Shift-right mouse click) to point to this executable. + 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 adds Emacs to "Start" menus and adds Emacs-related entries to the Windows Registry. + 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. Several helper programs are in a version-specific subdirectory of the libexec directory: + cmdproxy.exe - Used internally by Emacs to work around problems with the native shells in various versions of Windows. + ddeclient.exe - A tool for interacting with DDE servers. To be invoked as "ddeclient SERVER [TOPIC]", where SERVER is the DDE server name, and sends each line of its standard input to the DDE server using the DdeClientTransaction API. This program is supposed to be invoked via the 'call-process-region' Emacs primitive. + hexl.exe - A tool for producing hex dumps of binary files. 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. + profile.exe - A helper program that generates periodic events for profiling Emacs Lisp code. + update-game-score.exe - A utility for updating the score files of Emacs games. * Optional dependency libraries 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 from the same place from which you got this binary distribution. Emacs has a number of optional features which need additional libraries. These are provided in a separate bundle of dependencies, as described above, and enable support for the following: - displaying inline images of many types (PNG, JPEG, GIF, TIFF, SVG) - SSL/TLS secure network communications (HTTPS, IMAPS, etc.) - HTML and XML parsing (necessary for the built-in EWW browser) - built-in decompression of compressed text The optional dependency libraries are in emacs-MVER-x86_64-deps.zip (64-bit) and emacs-MVER-i686-deps.zip (32-bit), and their sources are in emacs-MVER-deps-mingw-w64-src.zip, where MVER is the major version of Emacs that should use these dependencies. Note that a 64-bit Emacs will only work with the 64-bit dependencies, and the 32-bit Emacs only with the 32-bit dependencies. Newer/updated builds for these optional libraries are available at http://msys2.github.io/ and http://sourceforge.net/projects/ezwinports/files/ (but you shouldn't need these except in emergencies). If you install the libraries in a directory different from where you have the Emacs executable programs, we recommend to add the directory with DLLs to your Path, so that Emacs will be able to find those DLLs when needed. * Installing Emacs with an existing MSYS2 installation You may also use Emacs with an existing MSYS2 installation by simply unpacking the Emacs distribution over MSYS2. You can then use the 'pacman' utility to install dependencies. You should not use the optional dependencies bundle from this site, as this will overwrite MSYS2 files (the dependency bundle derives from MSYS2, but may be a different version). Some of the optional libraries need to be of certain versions to work with your Emacs binary. Make sure you install those versions of dependencies, and no others. Emacs variables such as libpng-version and libjpeg-version tell what versions of the corresponding libraries are expected by Emacs. (We recommend that you use the dependency bundle, where these issues are always resolved.) To install the optional libraries, start the MSYS2 Bash window and type the following command: pacman -S PACKAGES where PACKAGES is the list of packages you want to install. The full list is as follows: mingw-w64-x86_64-giflib mingw-w64-x86_64-gnutls mingw-w64-x86_64-libjpeg-turbo mingw-w64-x86_64-libpng mingw-w64-x86_64-librsvg mingw-w64-x86_64-libtiff mingw-w64-x86_64-libxml2 mingw-w64-x86_64-xpm-nox You can type any subset of this list. When asked whether to proceed with installation, answer Y. Alternatively, you could install the packages manually from this page: https://sourceforge.net/projects/msys2/files/REPOS/MINGW/x86_64/ However, the packages there are not self-contained, so you will need to manually download all their dependencies as well. * 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 Start menu icon, this can be removed by right-clicking and "Uninstall". Finally, addpm.exe also creates a few registry entries; these can be safely left, but if you really wish to remove them, 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. * Troubleshooting Some known problems and their solutions can be found in the file etc\PROBLEMS in the unpacked Emacs distribution. 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). Windows 9X On Windows 9X, make sure you have the UNICOWS.DLL library either in the same directory where you have emacs.exe or in the directory where system-wide DLLs are kept. * Further information The Emacs User manual describes Windows-specific issues in the appendix named "Emacs and Microsoft Windows/MS-DOS". You can read it in Emacs by typing C-h r g Microsoft Windows RET This appendix is also available (as part of the entire manual) at https://www.gnu.org/software/emacs/manual/html_mono/emacs.html#Microsoft-Windows In addition to the manual, there is a mailing list for help with Emacs here: https://lists.gnu.org/mailman/listinfo/help-gnu-emacs To ask questions on this mailing list, send email to help-gnu-emacs@gnu.org. A mailing list for issues specifically related to the MS-Windows port of Emacs is here: https://lists.gnu.org/mailman/listinfo/help-emacs-windows To ask questions on this mailing list, send email to help-emacs-windows@gnu.org. * 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!
