+BASIC INSTALLATION
+
+The simplest way to build Emacs is to use the `configure' shell script
+which attempts to guess correct values for various system-dependent
+variables and features and find the directories where various system
+headers and libraries are kept. It then creates a `Makefile' in each
+subdirectory and a `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. If this simplified procedure fails, or if you
+are using a platform such as MS-Windows, where `configure' script
+doesn't work, you might need to use various non-default options, and
+maybe perform some of the steps manually. The more detailed
+description in the rest of the sections of this guide will help you do
+that, so please refer to them if the simple procedure does not work.
+
+ 1. If you want to be able to input international characters which
+ your keyboard doesn't support directly (i.e. you cannot type
+ them at the shell prompt), download the leim-M.N.tar.gz
+ distribution and unpack it into the same directory where you have
+ unpacked the main Emacs distribution. See ADDITIONAL
+ DISTRIBUTION FILES, below, for more about this.
+
+ 2. Make sure your system has at least 120 MB of free disk space.
+
+ 3a. `cd' to the directory where you unpacked Emacs and invoke the
+ `configure' script:
+
+ ./configure
+
+ 3b. 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.
+
+ 4. 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 will have to pass to `configure'
+ explicit machine configuration name, and one or more options
+ which tell it where to find various headers and libraries; refer
+ to DETAILED BUILDING AND INSTALLATION section below.
+
+ If `configure' didn't find some 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, assume that `configure' did its job and proceed.
+
+ 5. 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
+
+ 6. Invoke the `make' program:
+
+ make
+
+ 7. 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
+
+ 8. 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 also save some space by compressing (with `gzip') Info files
+ and installed Lisp source (.el) files which have corresponding .elc
+ versions.
+
+
+ADDITIONAL DISTRIBUTION FILES
+
+* leim-M.N.tar.gz
+
+The Emacs Lisp code for input methods for various international
+character scripts allows you to input characters in scripts which are
+not directly supported by your keyboard. It is distributed in a
+separate tar file because it amounts to a significant fraction of the
+size of the distribution. This tar file is called leim-M.N.tar.gz,
+with the same version number as Emacs, and it unpacks into the
+directory emacs-M.N/leim.
+
+You should unpack leim-M.N.tar.gz into the same directory where you
+have previously unpacked the main Emacs distribution. It fills in the
+contents of one subdirectory, which is present in the main Emacs
+distribution only in dummy form.
+
+Once you have unpacked the Leim tar file into the Emacs source tree,
+building and installing Emacs automatically installs the input method
+support as well. If you have built Emacs without unpacking Leim
+first, just unpack Leim, build Emacs again, and install it again.
+
+* intlfonts-VERSION.tar.gz
+
+The intlfonts distribution contains X11 fonts that Emacs needs in
+order 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 a font 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.
+* elisp-manual-M.N.tar.gz
-BUILDING AND INSTALLATION:
+This distribution contains the Emacs Lisp Reference Manual which
+complements the Emacs Manual. (The Emacs Manual is accessible from
+within the editor by typing "C-h i", then selecting the "Emacs" item
+from the menu, or by clicking "Help" in the menu bar and selecting
+"Read Emacs Manual".) It is a good idea to install the Emacs Lisp
+Reference Manual after installing Emacs, to complete the on-line
+documentation of Emacs in Info.
-(This is for a Unix or Unix-like system. For MSDOS, see below; search
-for MSDOG. For Windows NT or Windows 95, see the file nt/INSTALL.)
+If you have installed Texinfo, you can install the Emacs Lisp
+Reference Manual this way (after unpacking the elisp-manual-M.N.tar.gz
+file):
+
+ cd elisp-manual-M.N
+ ./configure --prefix=PREFIXDIR
+ make install
+
+Otherwise, you can install it manually. Just copy the files elisp and
+elisp-* from the elisp-manual-M.N directory to your site's info
+directory (see the description of `infodir', below), and make sure
+that file `dir' in this directory contains an entry like this:
+
+ * Elisp: (elisp). The Emacs Lisp Reference Manual.
+
+* 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. If not, you
+can download and build them from sources. None of them are vital for
+running Emacs; however, note that Emacs will not be able to use color
+icons in the toolbar if the XPM support is not available.
+
+Here's the list of these optional libraries, and the URLs where they
+can be found:
+
+ . libXaw3d for fancy 3D-style
+ scroll bars: ftp://ftp.x.org/contrib/widgets/Xaw3d/
+ . libxpm for XPM: ftp://ftp.x.org/contrib/libraries/
+ . libpng for PNG: ftp://www.libpng.org/pub/png/
+ . libz (for PNG): http://www.info-zip.org/pub/infozip/zlib/
+ . libjpeg for JPEG: ftp://ftp.uu.net/graphics/jpeg/
+ . libtiff for TIFF: http://www.libtiff.org/
+ . libungif for GIF:
+ http://prtr-13.ucsc.edu/~badger/software/libungif/index.shtml
+ Ensure you get version 4.1.0b1 or higher of libungif -- a bug in
+ 4.1.0 can crash Emacs.
+
+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'. See below for more details.
+
+
+DETAILED BUILDING AND INSTALLATION:

+(This is for a Unix or Unix-like system. For MS-DOS and Windows 3.X,
+see below; search for MSDOG. For Windows 9X, Windows ME, Windows NT,
+and Windows 2000, see the file nt/INSTALL. For the Mac, see the file
+mac/INSTALL.)

running the final dumped Emacs.

+and installation take place in different directories, then the
+installation procedure momentarily requires 95+60 MB (130+70 MB).
2) Consult `./etc/MACHINES' to see what configuration name you should
give to the `configure' program. That file offers hints for

+
+3) You can build Emacs in the top-level Emacs source directory
+or in a separate directory.
-3) In the top directory of the Emacs distribution, run the program
-`configure' as follows:
+3a) To build in the top-level Emacs source directory, go to that
+directory and run the program `configure' as follows:
- ./configure CONFIGURATION-NAME [--OPTION[=VALUE]] ...
+ ./configure [CONFIGURATION-NAME] [--OPTION[=VALUE]] ...
The CONFIGURATION-NAME argument should be a configuration name given
-in `./etc/MACHINES'. If omitted, `configure' will try to guess your
-system type; if it cannot, you must find the appropriate configuration
-name in `./etc/MACHINES' and specify it explicitly.

+
+You should try first omitting CONFIGURATION-NAME. This way,
+`configure' will try to guess your system type. If it cannot guess,
+or if something goes wrong in building or installing Emacs this way,
+try again specifying the proper CONFIGURATION-NAME 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

TOOLKIT is `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 ftom <http://www.lesstif.org>. Compiling with LessTif or
+Motif causes a standard File Selection Dialog to pop up when you type
+"C-x C-f" and similar commands. You can get fancy 3D-style scroll
+bars, even without LessTif/Motif, if you have the Xaw3d library
+installed (see "Image support libraries" above for Xaw3d
+availability).
The `--with-gcc' option specifies that the build process should
compile Emacs using GCC. If you don't want to use GCC, specify
`--with-gcc=no'. If you omit this option, `configure' will search
for GCC in your path, and use it if present.
-If you want the Emacs mail reader RMAIL to read mail from a POP
-server, you must specify `--with-pop'. This provides support for the
-POP3 protocol; older versions are not supported. For
-Kerberos-authenticated POP add `--with-kerberos', for Hesiod support
-add `--with-hesiod'. These options enable Emacs to use POP; whether
-Emacs uses POP is controlled by individual users--see the Rmail
-chapter of the Emacs manual.
-
-You can build Emacs for several different machine types from a single
-source directory. To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'. Make separate
-build directories for the different configuration types, and in each
-one, run the Emacs `configure' script. `configure' looks for the
-Emacs source code in the directory that `configure' is in.
+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. --without-xim disables the use of X Input Methods, and
+--disable-largefile omits support for files larger than 2GB on systems
+which support that.
The `--prefix=PREFIXDIR' option specifies where the installation process
should put emacs and its data files. This defaults to `/usr/local'.
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 fatures 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, and CC before
+running `configure'. CPPFLAGS lists the options passed to the
+preprocessor, 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.
+
+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.a and libbar.a
+libraries in addition to the standard ones.

The work of `configure' can be done by editing various files in the
-distribution, but using `configure' is supposed to be simpler. 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'.
+
+3c) Some people try to build in a separate directory by filling
+it full of symlinks to the files in the real source directory.
+If you do that, `make all' does work, but `make install' fails:
+it copies the symbolic links rather than the actual files.
+
+As far as is known, there is no particular reason to use
+a directory full of links rather than use the standard GNU
+facilities to build in a separate directory (see 3b above).
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
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.
+else, use site-init.el. Do not load byte-compiled code which
+was build 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
Note that, on some systems, the code you place in site-init.el must
not use expand-file-name or any other function which may look
something up in the system's password and user information database.

+DJECHO.EXE. These old versions of DJGPP shipped that program under
+the name ECHO.EXE, so you can simply copy ECHO.EXE to DJECHO.EXE and
+rerun CONFIG.BAT. If you have neither ECHO.EXE nor DJECHO.EXE, you
+should be able to find them in your djdevNNN.zip archive (where NNN is
+the DJGPP version number).
+
+To install the international fonts, chdir to the intlfonts-X.Y
+directory created when you unpacked the intlfonts distribution (X.Y is
+the version number of the fonts' distribution), and type the following
+command:
+
+ make bdf INSTALLDIR=..
+
+After Make finishes, you may remove the directory intlfonts-X.Y; the
+fonts are installed into the fonts/bdf subdirectory of the top-level
+Emacs directory, and that is where Emacs will look for them by

Building Emacs creates executable files in the src and lib-src
directories. Installing Emacs on MSDOS moves these executables to a
sibling directory called bin. For example, if you build in directory
/emacs, installing moves the executables from /emacs/src and
/emacs/lib-src to the directory /emacs/bin, so you can then delete the
subdirectories /emacs/src and /emacs/lib-src if you wish. The only
-subdirectories you need to keep are bin, lisp, etc and info. The bin

+subdirectory includes a PIF and an icon file for Emacs which you might
+find useful if you run Emacs under MS Windows.
Emacs on MSDOS finds the lisp, etc and info directories by looking in
../lisp, ../etc and ../info, starting from the directory where the
Emacs executable was run from. You can override this by setting the
-environment variable HOME; if you do that, the directories lisp, etc
-and info are accessed as subdirectories of the HOME directory.
+environment variables EMACSDATA (for the location of `etc' directory),
+EMACSLOADPATH (for the location of `lisp' directory) and INFOPATH (for
+the location of the `info' directory).
MSDOG is a not a multitasking operating system, so Emacs features such
as asynchronous subprocesses that depend on multitasking will not
work. Synchronous subprocesses do work.
-The current version of djgpp 2.0 (as of August 1996) has two bugs that
-affect Emacs. We've included corrected versions of two files from
-djgpp in the msdos subdirectory: is_exec.c and sigaction.c. To work
-around the bugs, compile these files and link them into temacs. The
-next version of djgpp should have these bugs fixed.
