ocamljava is an exciting looking project. It is a modification of the OCaml compiler so it targets Java bytecode. You can run unmodified OCaml programs on a JVM, call into Java libraries, call OCaml from Java and so on. It's fiendishly hard to build though, but after a few hours I have most of it compiled and a reasonable-looking srpm which only has a few rpmlint errors. I've opened a tracking bug for this if anyone else wants to have a go: https://bugzilla.redhat.com/show_bug.cgi?id=434560 Current spec file: http://www.annexia.org/tmp/ocaml/ocaml-ocamljava.spec Rich. -- Emerging Technologies, Red Hat - http://et.redhat.com/~rjones/ Registered Address: Red Hat UK Ltd, Amberley Place, 107-111 Peascod Street, Windsor, Berkshire, SL4 1TE, United Kingdom.
