Installing PSPP
***************

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.

 1. cd to the directory containing the PSPP source.

 2. Type ./configure to configure for your particular operating system and compiler.  Running configure takes a while.  While running, it displays some messages telling which features it is checking for.

     You can optionally supply some options to configure to give it hints about how to do its job.  Type ./configure --help to see a list of options.

 3. Type 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. See Submitting Bug Reports, for details.

 4. Type make check to run self-tests on the compiled PSPP package.

 5. Become the superuser and type make install to install the PSPP binaries, by default in /usr/local/bin/.  The directory /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 /usr/local/info/, but only if that directory already exists.

 6. (optional) Type make clean to delete the PSPP binaries from the source tree.
