GNU Prolog - http://www.gprolog.org
This compiler accepts Prolog + constraint programs and produces native binaries. The obtained executable is subsequently stand-alone. The size of this executable can be quite small since GNU Prolog can avoid linking the code of most unused built-in predicates. The performance of GNU Prolog is very encouraging (comparable to commercial systems). |
