Just a rule of thumb: Whenever your system setup changes (new GHC, new Cygwin, ...), you have to issue a "make distclean". But anyway, I don't have a clue what Andre's problem is.
[...] 1) the ghc 5.02.3 source distribution didnt come with happy, so i went and got it via CVS, and that fixed that.
Well, not exactly a HOpenGL problem... :-)
2) the HOpenGL distributed with the ghc 5.02.3 source would not compile.
The fptools/hslibs version of HOpenGL was an intermediate attempt to rewrite it more or less from scratch. But, as usual, GHC, the FFI, and the module hierarchy developed at a faster pace than I did, so I finally switched to the fptools/libraries hierarchy. There is a (small :-} hope that this will be *the* place for future Haskell libraries, so leaving the other versions as they are is the only choice I have with my limited resources. It could be the case that there will be a bug-fix release for 1.02, but the fptools/hslibs stuff is definitely dead and I should probably remove it from CVS. Sorry for the confusion.
3) no luck there, so i just downloaded the HOpenGL 1.2 source tarball, and the latest greencard tarball, compiled greencard and then had another go at compiling HOpenGL. And success ! all the examples compiled successfully too.
Congratulations! :-) The dependency on GreenCard is a big drawback in retrospect, it didn't become *the* way for interfacing with C as I hoped. Nevertheless, GreenCard paved the way for much cooler things like H/Direct and the current FFI. Thanks, Simon, Sigbjorn, and Thomas!
4) the only other thing that bothered me a bit was when i went to test the whole thing by compiling BezMesh.hs [...] I still dont know why the -package HOpenGL is necessary, but hey, its no big deal, i will probably work that out soon enough...
Have a look at: http://haskell.org/ghc/docs/latest/set/packages.html In a nutshell: A single "-package foo" can save you a plethora of GHC options, a simple but rather efficient and comfortable way to, well, 'package' them up... :-)
All in all the install on linux went relatively painlessly, considering what a huge and fearsome Beast the GHC is, and even HOpenGL aint exactly small either.
Things have definitely improved in the last 1-2 years: GHC finds its way to more and more platforms, and the "new" HOpenGL, using only the standard FFI, should be even less painful to install (or even *comes* with GHC, NHC98, Hugs, ... <= Hint ;-)
