I've already complained about that (=> Sigbjorn).

These are all harmless and are caused by two things:

    * The FFI syntax has changed a bit nowadays.

    * Haskell's FFI has no way to state the constness of arguments. This
      is a pity and even a 80% solution would be better than nothing.

Comment from Makefile.mk:

    # SUP: One of my greatest and most evil hacks...

:-} What happens when you comment out the evil line? Does "make depend"
still work then?

*aaargl* I forgot to include a patch for this in 1.05, see:

    http://haskell.org/pipermail/hopengl/2003-May/000389.html

Initially I hoped that the library infrastructure project would be
usable "soon", but now I think that as an intermediate measure a
home-grown solution will be needed. Alastair did similar things for
his subprojects, BTW. To make things easy, some restructuring of the
autoconf stuff in fptools will be necessary, but I'd prefer to wait
until the next Hugs and GHC releases are out.

Alas, no, at least not easily. You could try to get the HEAD of fptools,
do the usual autoreconf + configure, and then issue "make depend && make"
in the OpenGL and GLUT subdirectories. The hard part will be getting the
make variables right for the Haskell compiler to use, the installation
directories, etc. I haven't tried it yet, but somehow this should work.
