@cindex compiler, gcc
@pspp{} is written in ISO C and primarily targeted at UNIX-like
environments. To install @pspp{} under a UNIX-like operating system,
follow the steps below.
@enumerate
@item
@code{cd} to the directory containing the @pspp{} source.
@cindex configure, GNU
@cindex GNU configure
@item
Type @samp{./configure} to configure for your particular operating
system and compiler. Running @code{configure} takes a while. While
running, it displays some messages telling which features it is checking
for.
You can optionally supply some options to @code{configure} to
give it hints about how to do its job. Type @code{./configure --help}
to see a list of options.
@cindex compiling
@item
Type @samp{make} to compile the package. If there are any errors during
compilation, try to fix them. If modifications are necessary to compile
correctly under your configuration, contact the author.
@xref{Bugs,,Submitting Bug Reports}, for details.
@cindex self-tests, running
@item
Type @samp{make check} to run self-tests on the compiled @pspp{} package.
@cindex installation
@cindex @pspp{}, installing
@cindex @file{/usr/local/share/pspp/}
@cindex @file{/usr/local/bin/}
@cindex @file{/usr/local/info/}
@cindex documentation, installing
@item
Become the superuser and type @samp{make install} to install the
@pspp{} binaries, by default in @file{/usr/local/bin/}. The
directory @file{/usr/local/share/pspp/} is created and populated with
files needed by @pspp{} at runtime. This step will also cause the
@pspp{} documentation to be installed in @file{/usr/local/info/},
but only if that directory already exists.
@item
(optional) Type @samp{make clean} to delete the @pspp{} binaries
from the source tree.
@end enumerate
