If SWI-Prolog is not compiled with GMP support, it does not support

  1. Unbounded integers
  2. Rational numbers
  3. Various random number and cryptographic features

Affected libraries


  • If a binary distribution starts, but check_installation/0 reports GMP as missing, you should contact the packager of the distribution and point at this page.
  • The binary installations for MacOS and Windows provided by us bundle the GMP library. If there are issues, report them.
  • If you built from source, make sure the GMP development libraries are installed. Perform a fully new build afterwards and re-check.
