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.
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., 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
ADDITIONAL DISTRIBUTION FILES

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
directories, 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 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 easier. See the section called
