Linux

Follow the generic Unix commands in the page that links to this page, and normally you should be fine on Linux

The Python and Java interfaces to PLplot are generated with SWIG so if you want those interfaces you must install SWIG. If SWIG is installed and cmake cannot find it, then you must help cmake out by specifying the directory where swig.swg (an important SWIG file) is located using the CMAKE_INCLUDE_PATH environment variable. For example, one of our users reported success with finding SWIG and generating our Python and Java interfaces for Arch Linux by specifying

CMAKE_INCLUDE_PATH=/usr/share/swig/1.3.27

Normally, though, such extraordinary measures are not required on Linux.
