Download PARI/GP

If you intend to compile PARI/GP from a source distribution, make sure the GNU MP and GNU readline libraries are already installed on your system. They are not mandatory but make the gp calculator respectively faster and more user-friendly. (See the Extras section for details.)

Extras

The GNU readline library provides line editing under GP, an automatic context-dependent completion, and an editable history of commands.
The GNU MP library can be used as a replacement for the native multiprecision kernel. It is rather faster than the native kernel (benchmarks).
The PariEmacs package. Require PARI/GP-2.4.1 and up. GP can be run in an Emacs buffer, with all the obvious advantages if you are familiar with this editor. This package was developped alongside PARI/GP for a long time. It is now developped independently and must be downloaded separately. (In particular, PARI/GP and PariEmacs may be upgraded independently.)
perl (used by the gphelp script) provides extended online help (full text from this manual) about functions and concepts, which can be used under GP or independently.
