Node:Basic Installation, Next:Compilers and Options, Up:Running configure scripts
These are generic installation instructions.
The configure
shell script attempts to guess correct values
for various system-dependent variables used during compilation. It uses
those values to create a Makefile
in each directory of the
package. It may also create one or more .h
files containing
system-dependent definitions. Finally, it creates a shell script
config.status
that you can run in the future to recreate the
current configuration, and a file config.log
containing compiler
output (useful mainly for debugging configure
).
It can also use an optional file (typically called config.cache
and enabled with --cache-file=config.cache
or simply
-C
) that saves the results of its tests to speed up
reconfiguring. (Caching is disabled by default to prevent problems with
accidental use of stale cache files.)
If you need to do unusual things to compile the package, please try to
figure out how configure
could check whether to do them, and
mail diffs or instructions to the address given in the README
so
they can be considered for the next release. If you are using the
cache, and at some point config.cache
contains results you don't
want to keep, you may remove or edit it.
The file configure.ac
(or configure.in
) is used to create
configure
by a program called autoconf
. You only need
configure.ac
if you want to change it or regenerate
configure
using a newer version of autoconf
.
The simplest way to compile this package is:
cd
to the directory containing the package's source code and type
./configure
to configure the package for your system. If you're
using csh
on an old version of System V, you might need to type
sh ./configure
instead to prevent csh
from trying to
execute configure
itself.
Running configure
takes awhile. While running, it prints some
messages telling which features it is checking for.
make
to compile the package.
make check
to run any self-tests that come with
the package.
make install
to install the programs and any data files and
documentation.
make clean
. To also remove the files
that configure
created (so you can compile the package for a
different kind of computer), type make distclean
. There is also
a make maintainer-clean
target, but that is intended mainly for
the package's developers. If you use it, you may have to get all sorts
of other programs in order to regenerate files that came with the
distribution.
