It looks like you're using one of the old versions (1.0x) of HOpenGL from http://haskell.org/HOpenGL, which are not supported anymore. The development takes place in the fptools CVS repository now, so GHC, Hugs and NHC can use it more easily. I don't know much about Gentoo Linux, but it looks like that there is a GHC 6.2.1 in dev-lang/ghc. This is almost what you want... :-) It already contains some basic OpenGL functionality, but being on a release branch, it doesn't have all the features of the CVS main branch (full OpenGL 1.5 support apart from NURBS, API docs at http://haskell.org/HOpenGL/newAPI/). So you are basically left with 2 options: * Wait for the official release of GHC 6.4, but this will probably take some time. * Build GHC from the CVS main branch or the nightly snapshots (available at http://www.haskell.org/ghc/dist/current/dist/). I've got no idea how to do this via the ebuild system, but perhaps Andres Loeh can help. He seems to be the maintainer/packager for GHC on Gentoo. If you can live without a properly packaged GHC version, simply doing things by hand is not that hard nowadays (given that you have sufficiently recent versions of Alex, Happy and Haddock installed): cd fptools (or whatever the toplevel directory is called) autoreconf ./configure --enable-hopengl make all make html make install make install-docs Depending on your needs, you might want to use the --prefix and/or --libdir options of configure. Building Hugs from CVS with OpenGL support is not that hard, either: cg hugs98 (or whatever the toplevel directory is called) make EXTRA_CONFIGURE_OPTS="--enable-hopengl" Well, I should really update my HOpenGL web pages... :-] Cheers, S.
