Nice to hear! :-)

Could you send your changes? Perhaps I can make an "ultra-last"
release of the HOpenGL-1.0x series if it is worthwhile. And which demos
fail exactly?

Again, the changes would be interesting. Wolfgang Thaller, who seems
to be "Mr. Mac" on this mailing list, has probably done something
similar, so it would be nice to hear from him about HOpenGL 1.04, too.

The interest in Macs seems to be growing since Apple ships a more
"mainstream" OS, but, alas, I don't have access to such a platform.
This means that I depend on other people to get/keep HOpenGL running
there. The current development for HOpenGL happens in the fptools
repository, but I can only test on x86 Linux (SuSE) and WinDoze. Are
there any people on this list building a GHC from CVS on a different
platform (esp. Macs)? If yes, it would be helpful if they could try
using configure's --enable-hopengl option and report on the outcome of
the compilation. fptools/libraries/GLUT/examples contains some simple
examples for testing.

Apart from tweaking some options for the preprocessor and the linker,
fptools/libraries/OpenGL/{include/HsOpenGL.h,cbits/HsOpenGL.c} will
probably need some attention on new platforms. They handle the OpenGL
extension mechanism for GLX (most *nices) and WGL (WinDoze), but
things are different on Macs.
