No problem, that's what mailing lists are for...

That's exactly what I meant with "rather incomplete"... :-} It
compiles & links fine using your commandline with the CVS HEAD, but
not with 5.04.3. But there's still HOpenGL 1.04... (*hint* *hint* :-)

Sorry for this confusing versionitis, but keeping up with the evolving
OpenGL standard, FFI standardization and changing Haskell libraries is
sometimes a bit tough. I hope that in a few months the CVS version
will be usable enough to release a brand-new HOpenGL-2.0 (hmmm, or
should it better be called "1.4"?), offering full OpenGL 1.4 support,
hierarchical libraries, extensive online documentation, etc.

Cheers,
