For information about building from a Bazaar checkout +(rather than a release), also read the file INSTALL.BZR. + + +BASIC INSTALLATION + +On most Unix systems, you build Emacs by first running the `configure' +shell script. This attempts to deduce the correct values for +various system-dependent variables and features, and find the +directories where certain system headers and libraries are kept. +In a few cases, you may need to explicitly tell configure where to +find some things, or what options to use. + +`configure' creates a `Makefile' in several subdirectories, and a +`src/config.h' file containing system-dependent definitions. +Running the `make' utility then builds the package for your system. + +Here's the procedure to build Emacs using `configure' on systems which +are supported by it. In some cases, if the simplified procedure fails, +you might need to use various non-default options, and maybe perform +some of the steps manually. The more detailed description in the other +sections of this guide will help you do that, so please refer to those +sections if you need to. + + 1. Unpacking the Emacs 23.2 release requires about 170 MB of free + disk space. Building Emacs uses about another 60 MB of space. + The final installed Emacs uses about 120 MB of disk space. + This includes the space-saving that comes from automatically + compressing the Lisp source files on installation. + + 2a. `cd' to the directory where you unpacked Emacs and invoke the + `configure' script: + + ./configure + + 2b. Alternatively, create a separate directory, outside the source + directory, where you want to build Emacs, and invoke `configure' + from there: + + SOURCE-DIR/configure + + where SOURCE-DIR is the top-level Emacs source directory. + This may not work unless you use GNU make. + + 3. When `configure' finishes, it prints several lines of details + about the system configuration. Read those details carefully + looking for anything suspicious, such as wrong CPU and operating + system names, wrong places for headers or libraries, missing + libraries that you know are installed on your system, etc. + + If you find anything wrong, you may have to pass to `configure' + one or more options specifying the explicit machine configuration + name, where to find various headers and libraries, etc. + Refer to the section DETAILED BUILDING AND INSTALLATION below. + + If `configure' didn't find some (optional) image support libraries, + such as Xpm, jpeg, etc., and you want to use them, refer to the + subsection "Image support libraries" below. + + If the details printed by `configure' don't make any sense to + you, but there are no obvious errors, assume that `configure' did + its job and proceed. + + 4. If you need to run the `configure' script more than once (e.g., + with some non-default options), always clean the source + directories before running `configure' again: + + make distclean + ./configure + + 5. Invoke the `make' program: + + make + + 6. If `make' succeeds, it will build an executable program `emacs' + in the `src' directory. You can try this program, to make sure + it works: + + src/emacs -Q + + 7. Assuming that the program `src/emacs' starts and displays its + opening screen, you can install the program and its auxiliary + files into their installation directories: + + make install + + You are now ready to use Emacs. If you wish to conserve disk space, + you may remove the program binaries and object files from the + directory where you built Emacs: + + make clean + + You can delete the entire build directory if you do not plan to + build Emacs again, but it can be useful to keep for debugging. + + Note that the install automatically saves space by compressing + (provided you have the `gzip' program) those installed Lisp source (.el) + files that have corresponding .elc versions, as well as the Info files. + + +ADDITIONAL DISTRIBUTION FILES + +* Complex Text Layout support libraries + +Emacs needs the optional libraries "m17n-db", "libm17n-flt", "libotf" +to correctly display such complex scripts as Indic and Khmer. +On some systems, particularly GNU/Linux, these libraries may be +already present or available as additional packages. Note that if +there is a separate `dev' or `devel' package, for use at compilation +time rather than run time, you will need that as well as the +corresponding run time package; typically the dev package will contain +header files and a library archive. Otherwise, you can download and +build libraries from sources. + +The sources of these libraries are available by anonymous CVS from +cvs.m17n.org. + + % cvs -d :pserver:anonymous@cvs.m17n.org:/cvs/m17n login + % cvs -d :pserver:anonymous@cvs.m17n.org:/cvs/m17n co m17n-db + % cvs -d :pserver:anonymous@cvs.m17n.org:/cvs/m17n co m17n-lib + % cvs -d :pserver:anonymous@cvs.m17n.org:/cvs/m17n co libotf + +For m17n-lib, if you have problems with making the whole package +because you lack some other packages on which m17n-lib depends, try to +configure it with the option "--without-gui". + +* intlfonts-VERSION.tar.gz + +The intlfonts distribution contains X11 fonts in various encodings +that Emacs can use to display international characters. If you see a +non-ASCII character appear as a hollow box, that means you don't have +a font for it. You might find one in the intlfonts distribution. If +you do have a font for a non-ASCII character, but some characters +don't look right, or appear improperly aligned, a font from the +intlfonts distribution might look better. + +The fonts in the intlfonts distribution are also used by the ps-print +package for printing international characters. The file +lisp/ps-mule.el defines the *.bdf font files required for printing +each character set. + +The intlfonts distribution contains its own installation instructions, +in the intlfonts/README file. + +* Image support libraries + +Emacs needs optional libraries to be able to display images (with the +exception of PBM and XBM images whose support is built-in). + +On some systems, particularly on GNU/Linux, these libraries may +already be present or available as additional packages. Note that if +there is a separate `dev' or `devel' package, for use at compilation +time rather than run time, you will need that as well as the +corresponding run time package; typically the dev package will +contain header files and a library archive. Otherwise, you can +download and build libraries from sources. None of them are vital for +running Emacs; however, note that Emacs will not be able to use +colored icons in the toolbar if XPM support is not compiled in. + +Here's the list of some of these optional libraries, and the URLs +where they can be found (in the unlikely event that your distribution +does not provide them): + + . libXaw3d http://directory.fsf.org/project/xaw3d/ + . libxpm for XPM: http://www.x.org/releases/current/src/lib/ + . libpng for PNG: http://www.libpng.org/ + . libz (for PNG): http://www.zlib.net/ + . libjpeg for JPEG: http://www.ijg.org/ + . libtiff for TIFF: http://www.libtiff.org/ + . libgif for GIF: http://sourceforge.net/projects/giflib/ + +Emacs will configure itself to build with these libraries if the +`configure' script finds them on your system, unless you supply the +appropriate --without-LIB option. In some cases, older versions of +these libraries won't work because some routines are missing, and +configure should avoid such old versions. If that happens, use the +--without-LIB options to `configure', if you need to. + +* Extra fonts + +The Emacs distribution does not include fonts and does not install +them. + +On the GNU system, Emacs supports both X fonts and local fonts +(i.e. fonts managed by the fontconfig library). If you need more +fonts than your distribution normally provides, you must install them +yourself. See <URL:http://www.gnu.org/software/freefont/> for a large +number of free Unicode fonts. + +* GNU/Linux development packages + +Many GNU/Linux systems do not come with development packages by default; +they include the files that you need to run Emacs, but not those you +need to compile it. For example, to compile Emacs with support for X +and graphics libraries, you may need to install the `X development' +package(s), and development versions of the jpeg, png, etc. packages. + +The names of the packages that you need varies according to the +GNU/Linux distribution that you use, and the options that you want to +configure Emacs with. On Debian-based systems, you can install all the +packages needed to build the installed version of Emacs with a command +like `apt-get build-dep emacs23'. + + +DETAILED BUILDING AND INSTALLATION: + +(This is for a Unix or Unix-like system. For MS-DOS and MS Windows 3.X, +see msdos/INSTALL. For later versions of MS Windows, see the file +nt/INSTALL. For GNUstep and Mac OS X, see nextstep/INSTALL.) + +1) Make sure your system has enough swapping space allocated to handle +a program whose pure code is 1.5 MB and whose data area is at +least 2.8 MB and can reach 100 MB or more. If the swapping space is +insufficient, you will get an error in the command `temacs -batch -l +loadup dump', found in `./src/Makefile.in', or possibly when +running the final dumped Emacs. (This should not be an issue +on any recent system.) + +Building Emacs requires about 230 MB of disk space (including the +Emacs sources). Once installed, Emacs occupies about 120 MB in the file +system where it is installed; this includes the executable files, Lisp +libraries, miscellaneous data files, and on-line documentation. If +the building and installation take place in different directories, +then the installation procedure momentarily requires 230+120 MB. + +2) In the unlikely event that `configure' does not detect your system +type correctly, consult `./etc/MACHINES' to see what --host, --build +options you should pass to `configure'. That file also offers hints +for getting around some possible installation problems. + +3) You can build Emacs in the top-level Emacs source directory +or in a separate directory. + +3a) To build in the top-level Emacs source directory, go to that +directory and run the program `configure' as follows: + + ./configure [--OPTION[=VALUE]] ... + +If `configure' cannot determine your system type, try again +specifying the proper --build, --host options explicitly. + +If you don't want X support, specify `--with-x=no'. If you omit this +option, `configure' will try to figure out for itself whether your +system has X, and arrange to use it if present. + +The `--x-includes=DIR' and `--x-libraries=DIR' options tell the build +process where the compiler should look for the include files and +object libraries used with the X Window System. Normally, `configure' +is able to find them; these options are necessary if you have your X +Window System files installed in unusual places. These options also +accept a list of directories, separated with colons. + +To get more attractive menus, you can specify an X toolkit when you +configure Emacs; use the option `--with-x-toolkit=TOOLKIT', where +TOOLKIT is `gtk' (the default), `athena', or `motif' (`yes' and +`lucid' are synonyms for `athena'). On some systems, it does not work +to use a toolkit with shared libraries. A free implementation of +Motif, called LessTif, is available from <http://www.lesstif.org>. +Compiling with LessTif or Motif causes a standard File Selection +Dialog to pop up when you invoke file commands with the mouse. You +can get fancy 3D-style scroll bars, even without Gtk or LessTif/Motif, +if you have the Xaw3d library installed (see "Image support libraries" +above for Xaw3d availability). + +You can tell configure where to search for GTK by specifying +`--with-pkg-config-prog=PATH' where PATH is the pathname to +pkg-config. Note that GTK version 2.6 or newer is required for Emacs. + +The Emacs mail reader RMAIL is configured to be able to read mail from +a POP3 server by default. Versions of the POP protocol older than +POP3 are not supported. For Kerberos-authenticated POP add +`--with-kerberos', for Hesiod support add `--with-hesiod'. While POP3 +is always enabled, whether Emacs actually uses POP is controlled by +individual users--see the Rmail chapter of the Emacs manual. + +For image support you may have to download, build, and install the +appropriate image support libraries for image types other than XBM and +PBM, see the list of URLs in "ADDITIONAL DISTRIBUTION FILES" above. +(Note that PNG support requires libz in addition to libpng.) + +To disable individual types of image support in Emacs for some reason, +even though configure finds the libraries, you can configure with one +or more of these options: + + --without-xpm for XPM image support + --without-jpeg for JPEG image support + --without-tiff for TIFF image support + --without-gif for GIF image support + --without-png for PNG image support + +Use --without-toolkit-scroll-bars to disable LessTif/Motif or Xaw3d +scroll bars. + +Use --without-xim to inhibit the default use of X Input Methods. +In this case, the X resource useXIM can be used to turn on use of XIM. + +Use --disable-largefile to omit support for files larger than 2GB on +systems which support that. + +Use --without-sound to disable sound support. + +The `--prefix=PREFIXDIR' option specifies where the installation process +should put emacs and its data files. This defaults to `/usr/local'. +- Emacs (and the other utilities users run) go in PREFIXDIR/bin + (unless the `--exec-prefix' option says otherwise). +- The architecture-independent files go in PREFIXDIR/share/emacs/VERSION + (where VERSION is the version number of Emacs, like `23.2'). +- The architecture-dependent files go in + PREFIXDIR/libexec/emacs/VERSION/CONFIGURATION + (where CONFIGURATION is the configuration name, like + i686-pc-linux-gnu), unless the `--exec-prefix' option says otherwise. + +The `--exec-prefix=EXECDIR' option allows you to specify a separate +portion of the directory tree for installing architecture-specific +files, like executables and utility programs. If specified, +- Emacs (and the other utilities users run) go in EXECDIR/bin, and +- The architecture-dependent files go in + EXECDIR/libexec/emacs/VERSION/CONFIGURATION. +EXECDIR/bin should be a directory that is normally in users' PATHs. + +For example, the command + + ./configure --build=i386-linux-gnu --without-sound + +configures Emacs to build for a 32-bit GNU/Linux distribution, +without sound support. + +`configure' doesn't do any compilation or installation itself. +It just creates the files that influence those things: +`./Makefile' in the top-level directory and several subdirectories; +and `./src/config.h'. For details on exactly what it does, see the +section called `CONFIGURATION BY HAND', below. + +When it is done, `configure' prints a description of what it did and +creates a shell script `config.status' which, when run, recreates the +same configuration. If `configure' exits with an error after +disturbing the status quo, it removes `config.status'. `configure' +also creates a file `config.cache' that saves the results of its tests +to make reconfiguring faster, and a file `config.log' containing compiler +output (useful mainly for debugging `configure'). You can give +`configure' the option `--cache-file=FILE' to use the results of the +tests in FILE instead of `config.cache'. Set FILE to `/dev/null' to +disable caching, for debugging `configure'. + +If the description of the system configuration printed by `configure' +is not right, or if it claims some of the features or libraries are not +available when you know they are, look at the `config.log' file for +the trace of the failed tests performed by `configure' to check +whether these features are supported. Typically, some test fails +because the compiler cannot find some function in the system +libraries, or some macro-processor definition in the system headers. + +Some tests might fail because the compiler should look in special +directories for some header files, or link against optional +libraries, or use special compilation options. You can force +`configure' and the build process which follows it to do that by +setting the variables CPPFLAGS, CFLAGS, LDFLAGS, LIBS, CPP and CC +before running `configure'. CPP is the command which invokes the +preprocessor, CPPFLAGS lists the options passed to it, CFLAGS are +compilation options, LDFLAGS are options used when linking, LIBS are +libraries to link against, and CC is the command which invokes the +compiler. By default, gcc is used if available. + +Here's an example of a `configure' invocation, assuming a Bourne-like +shell such as Bash, which uses these variables: + + CPPFLAGS='-I/foo/myinclude' LDFLAGS='-L/bar/mylib' \ + CFLAGS='-O3' LIBS='-lfoo -lbar' ./configure + +(this is all one long line). This tells `configure' to instruct the +preprocessor to look in the `/foo/myinclude' directory for header +files (in addition to the standard directories), instruct the linker +to look in `/bar/mylib' for libraries, pass the -O3 optimization +switch to the compiler, and link against libfoo and libbar +libraries in addition to the standard ones. + +For some libraries, like Gtk+, fontconfig and ALSA, `configure' uses +pkg-config to find where those libraries are installed. +If you want pkg-config to look in special directories, you have to set +the environment variable PKG_CONFIG_PATH to point to the directories +where the .pc-files for those libraries are. +For example: + + PKG_CONFIG_PATH='/usr/local/alsa/lib/pkgconfig:/opt/gtk+-2.8/lib/pkgconfig' \ + ./configure + +The work of `configure' can be done by editing various files in the +distribution, but using `configure' is easier. See the section called +"CONFIGURATION BY HAND" below if you want to do the configuration +yourself. + +3b) To build in a separate directory, go to that directory +and run the program `configure' as follows: + + SOURCE-DIR/configure CONFIGURATION-NAME [--OPTION[=VALUE]] ... + +SOURCE-DIR refers to the top-level Emacs source directory which is +where Emacs's configure script is located. `configure' looks for the +Emacs source code in the directory that `configure' is in. + +To build in a separate directory, you must use a version of `make' +that supports the `VPATH' variable, such as GNU `make'. + +(Do not try to build in a separate directory by creating many links +to the real source directory--there is no need, and installation will +fail.) + +4) Look at `./lisp/paths.el'; if some of those values are not right +for your system, set up the file `./lisp/site-init.el' with Emacs +Lisp code to override them; it is not a good idea to edit paths.el +itself. YOU MUST USE THE LISP FUNCTION `setq' TO ASSIGN VALUES, +rather than `defvar', as used by `./lisp/paths.el'. For example, + + (setq news-inews-program "/usr/bin/inews") + +is how you would override the default value of the variable +news-inews-program. + +Before you override a variable this way, *look at the value* that the +variable gets by default! Make sure you know what kind of value the +variable should have. If you don't pay attention to what you are +doing, you'll make a mistake. + +5) Put into `./lisp/site-init.el' or `./lisp/site-load.el' any Emacs +Lisp code you want Emacs to load before it is dumped out. Use +site-load.el for additional libraries if you arrange for their +documentation strings to be in the etc/DOC file (see +src/Makefile.in if you wish to figure out how to do that). For all +else, use site-init.el. Do not load byte-compiled code which +was built with a non-nil value of `byte-compile-dynamic'. + +If you set load-path to a different value in site-init.el or +site-load.el, Emacs will use *precisely* that value when it starts up +again. If you do this, you are on your own! + +The `site-*.el' files are nonexistent in the distribution. You do not +need to create them if you have nothing to put in them. + +6) Refer to the file `./etc/TERMS' for information on fields you may +wish to add to various termcap entries. (This is unlikely to be necessary.) + +7) Run `make' in the top directory of the Emacs distribution to finish +building Emacs in the standard way. The final executable file is +named `src/emacs'. You can execute this file "in place" without +copying it, if you wish; then it automatically uses the sibling +directories ../lisp, ../lib-src, ../info. + +Or you can "install" the executable and the other files into their +installed locations, with `make install'. By default, Emacs's files +are installed in the following directories: + +`/usr/local/bin' holds the executable programs users normally run - + `emacs', `etags', `ctags', `emacsclient', + `grep-changelog', and `rcs-checkin'. + +`/usr/local/share/emacs/VERSION/lisp' holds the Emacs Lisp library; + `VERSION' stands for the number of the Emacs version + you are installing, like `23.1' or `23.2'. Since the + Lisp library changes from one version of Emacs to + another, including the version number in the path + allows you to have several versions of Emacs installed + at the same time; in particular, you don't have to + make Emacs unavailable while installing a new version. + +`/usr/local/share/emacs/VERSION/etc' holds the Emacs tutorial, the DOC + file, and other architecture-independent files Emacs + might need while running. + +`/usr/local/libexec/emacs/VERSION/CONFIGURATION-NAME' contains executable + programs used by Emacs that users are not expected to + run themselves. + `VERSION' is the number of the Emacs version you are + installing, and `CONFIGURATION-NAME' is the value + deduced by the `configure' program to identify the + architecture and operating system of your machine, + like `i686-pc-linux-gnu' or `sparc-sun-sunos'. Since + these files are specific to the version of Emacs, + operating system, and architecture in use, including + the configuration name in the path allows you to have + several versions of Emacs for any mix of machines and + operating systems installed at the same time; this is + useful for sites at which different kinds of machines + share the file system Emacs is installed on. + +`/usr/local/share/info' holds the on-line documentation for Emacs, + known as "info files". Many other GNU programs are + documented using info files as well, so this directory + stands apart from the other, Emacs-specific directories. + +`/usr/local/share/man/man1' holds the man pages for the programs installed + in `/usr/local/bin'. + +Any version of Emacs, whether installed or not, also looks for Lisp +files in these directories. + +`/usr/local/share/emacs/VERSION/site-lisp' holds the local Emacs Lisp + files installed for Emacs version VERSION only. + +`/usr/local/share/emacs/site-lisp' holds the local Emacs Lisp + files installed for all Emacs versions. + + When Emacs is installed, it searches for its Lisp files + in `/usr/local/share/emacs/VERSION/site-lisp', then in + `/usr/local/share/emacs/site-lisp', and finally in + `/usr/local/share/emacs/VERSION/lisp'. + +If these directories are not what you want, you can specify where to +install Emacs's libraries and data files or where Emacs should search +for its Lisp files by giving values for `make' variables as part of +the command. See the section below called `MAKE VARIABLES' for more +information on this. + +8) Check the file `dir' in your site's info directory (usually +/usr/local/share/info) to make sure that it has a menu entry for the +Emacs info files. + +9) If your system uses lock files to interlock access to mailer inbox files, +then you might need to make the movemail program setuid or setgid +to enable it to write the lock files. We believe this is safe. + +10) You are done! You can remove executables and object files from +the build directory by typing `make clean'. To also remove the files +that `configure' created (so you can compile Emacs for a different +configuration), type `make distclean'. If you don't need some, or all +of the input methods from the Leim package, you can remove the +unneeded files in the leim subdirectories of your site's lisp +directory (usually /usr/local/share/emacs/VERSION/). + + + +MAKE VARIABLES + +You can change where the build process installs Emacs and its data +files by specifying values for `make' variables as part of the `make' +command line. For example, if you type + + make install bindir=/usr/local/gnubin + +the `bindir=/usr/local/gnubin' argument indicates that the Emacs +executable files should go in `/usr/local/gnubin', not +`/usr/local/bin'. + +Here is a complete list of the variables you may want to set. + +`bindir' indicates where to put executable programs that users can + run. This defaults to /usr/local/bin. + +`datadir' indicates where to put the architecture-independent + read-only data files that Emacs refers to while it runs; it + defaults to /usr/local/share. We create the following + subdirectories under `datadir': + - `emacs/VERSION/lisp', containing the Emacs Lisp library, and + - `emacs/VERSION/etc', containing the tutorials, DOC file, etc. + `VERSION' is the number of the Emacs version you are installing, + like `23.1' or `23.2'. Since these files vary from one version + of Emacs to another, including the version number in the path + allows you to have several versions of Emacs installed at the + same time; this means that you don't have to make Emacs + unavailable while installing a new version. + +`libexecdir' indicates where to put architecture-specific data files that + Emacs refers to as it runs; it defaults to `/usr/local/libexec'. + We create the following subdirectories under `libexecdir': + - `emacs/VERSION/CONFIGURATION-NAME', containing executable + programs used by Emacs that users are not expected to run + themselves. + `VERSION' is the number of the Emacs version you are installing, + and `CONFIGURATION-NAME' is the value deduced by the + `configure' program to identify the architecture and operating + system of your machine, like `i686-pc-linux-gnu' or `sparc-sun-sunos'. + Since these files are specific to the version of Emacs, + operating system, and architecture in use, including the + configuration name in the path allows you to have several + versions of Emacs for any mix of machines and operating + systems installed at the same time; this is useful for sites + at which different kinds of machines share the file system + Emacs is installed on. + +`infodir' indicates where to put the info files distributed with + Emacs; it defaults to `/usr/local/share/info'. + +`mandir' indicates where to put the man pages for Emacs and its + utilities (like `etags'); it defaults to + `/usr/local/share/man/man1'. + +`prefix' doesn't give a path for any specific part of Emacs; instead, + its value is used to determine the defaults for all the + architecture-independent path variables - `datadir', + `sharedstatedir', `infodir', and `mandir'. Its default value is + `/usr/local'; the other variables add on `lib' or `man' to it + by default. + + For example, suppose your site generally places GNU software + under `/usr/users/software/gnusoft' instead of `/usr/local'. + By including + `prefix=/usr/users/software/gnusoft' + in the arguments to `make', you can instruct the build process + to place all of the Emacs data files in the appropriate + directories under that path. + +`exec_prefix' serves the same purpose as `prefix', but instead + determines the default values for the architecture-dependent + path variables - `bindir' and `libexecdir'. + +The above variables serve analogous purposes in the makefiles for all +GNU software; the following variable is specific to Emacs. + +`archlibdir' indicates where Emacs installs and expects the executable + files and other architecture-dependent data it uses while + running. Its default value, based on `libexecdir' (which + see), is `/usr/local/libexec/emacs/VERSION/CONFIGURATION-NAME' + (where VERSION and CONFIGURATION-NAME are as described above). + +Remember that you must specify any variable values you need each time +you run `make' in the top directory. If you run `make' once to build +emacs, test it, and then run `make' again to install the files, you +must provide the same variable settings each time. To make the +settings persist, you can edit them into the `Makefile' in the top +directory, but be aware that running the `configure' program erases +`Makefile' and rebuilds it from `Makefile.in'. + +The path for finding Lisp files is specified in src/epaths.h, +a file which is generated by running configure. To change the path, +you can edit the definition of PATH_LOADSEARCH in that file +before you run `make'. + +The top-level Makefile stores the variable settings it used in the +Makefiles for the subdirectories, so you don't have to specify them +when running make in the subdirectories. + + +CONFIGURATION BY HAND + +This should not be necessary and is not recommended. Instead of +running the `configure' program, you have to perform the following steps. + +1) Copy `./src/config.in' to `./src/config.h'. + +2) Consult `./etc/MACHINES' to see what configuration name you should +use for your system. Look at the code of the `configure' script to +see which operating system and architecture description files from +`src/s' and `src/m' should be used for that configuration name. Edit +`src/config.h', and change the two `#include' directives to include +the appropriate system and architecture description files. + +2) Edit `./src/config.h' to set the right options for your system. If +you need to override any of the definitions in the s/*.h and m/*.h +files for your system and machine, do so by editing config.h, not by +changing the s/*.h and m/*.h files. + +3) Create `Makefile' files in various directories from the +corresponding `Makefile.in' files. This isn't so hard, just a matter +of editing in appropriate substitutions for the @...@ constructs. + +The `configure' script is built from `configure.in' by the `autoconf' +program. You need at least the version of autoconf specified in the +AC_PREREQ(...) command to rebuild `configure' from `configure.in'. + +BUILDING GNU EMACS BY HAND + +Once Emacs is configured, running `make' in the top directory performs +the following steps. + +1) Run `make epaths-force' in the top directory. This produces +`./src/epaths.h' from the template file `./src/epaths.in', changing +the paths to the values specified in `./Makefile'. + +2) Go to directory `./lib-src' and run `make'. This creates +executables named `etags', `make-docfile', and others. + +3) Go to directory `./src' and run `make'. This refers to files in +the `./lisp' and `./lib-src' subdirectories using names `../lisp' and +`../lib-src'. + +This creates a file `./src/emacs' which is the runnable Emacs, +which has another name that contains a version number. +Each time you do this, that version number increments in the last place. + +It also creates a file in `./etc' whose name is `DOC' followed by the +current Emacs version. This file contains documentation strings for +all the functions in Emacs. Each time you run make to make a new +emacs, a new DOC file with a new name is made. You must keep the DOC +file for an Emacs version as long as you keep using that Emacs version. + + +INSTALLATION BY HAND + +The steps below are done by running `make install' in the main +directory of the Emacs distribution. + +1) Copy `./lisp' and its subdirectories, `./etc', and the executables +in `./lib-src' to their final destinations, as selected in `./src/epaths.h'. + +Strictly speaking, not all of the executables in `./lib-src' need be copied. +- The programs `fakemail', `hexl', `movemail', `profile', `rcs2log', + and `vcdiff' are used by Emacs; they do need to be copied. +- The programs `etags', `ctags', `emacsclient', and `rcs-checkin' + are intended to be run by users; they are handled below. +- The programs `make-docfile' and `test-distrib' were + used in building Emacs, and are not needed any more. + +2) Copy the files in `./info' to the place specified in +`./lisp/site-init.el' or `./lisp/paths.el'. Note that if the +destination directory already contains a file named `dir', you +probably don't want to replace it with the `dir' file in the Emacs +distribution. Instead, you should make sure that the existing `dir' +file contains an appropriate menu entry for the Emacs info. + +3) Copy `./src/emacs' to `/usr/local/bin', or to some other directory +in users' search paths. `./src/emacs' has an alternate name +`./src/emacs-EMACSVERSION'; you may wish to make a symbolic link named +`/usr/local/bin/emacs' pointing to that alternate name, as an easy way +of installing different versions. + +You can delete `./src/temacs'. + +4) Copy the programs `emacsclient', `ctags', `etags', and `rcs-checkin' +from `./lib-src' to `/usr/local/bin'. These programs are intended for +users to run. + +5) Copy the man pages in `./doc/man' into the appropriate man directory. + +6) The files in the `./src' subdirectory, except for `emacs', are not +used by Emacs once it is built. However, it is very desirable to keep +the source on line for debugging. + + +PROBLEMS + +See the file `./etc/PROBLEMS' for a list of various problems sometimes +encountered, and what to do about them. + +This file is part of GNU Emacs. + +GNU Emacs is free software: you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation, either version 3 of the License, or +(at your option) any later version. + +GNU Emacs is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
