The current /trunk FPC version (2.5.1) and the /branches/fixes_2_4 (the upcoming 2.4 release) already include an initial version of a Free Pascal interface for the GNU Multiple Precision Arithmetic Library in packages/gmp.

To use the bindings in your projects (and be able to build them) you have to:

• Include gmp in the uses clause of a program/unit source from which you will use the GMP types/functions.
• Have the gmp library installed on your system
  • Most, if not all, *nix systems have GMP (libgmp) installed by default but it is still necessary to have the dev package (libgmpX-dev) installed also (needed in the link stage). This package is not included by default everywhere (eg. Ubuntu).
  • On Windows, you can get the mingw-dynamic package and rename it to gmp.dll.
  • On Mac OS X, gmp can be installed as documented on gmplib.org or using the package managers MacPorts or Fink.
• Have the necessary knowledge of the GMP documentation.
