GNU Prolog is a free Prolog compiler with constraint solving over finite domains. It accepts a Prolog+ constraint program and produces a native binary. The obtained executable is now stand-alone. This executable can be quite small since GNU Prolog doesn't need to link the code of most unused built-in predicates. Besides the native code compilation, GNU Prolog offers a classical interactive interpreter (top-level). It also conforms to the ISO standard for Prolog. The program also includes an efficient constraint solver over Finite Domains (FD). This opens constraint logic programming to the user, combining its power with the declarativity of logic programming.
