[...] There's a small problem even then:
Just a few days ago, I wanted to test HOpenGL for something and noticed the following (which happens both with the CVS version and with 6.2.1):
$ ghci-cvs -package OpenGL ___ ___ _ / _ \ /\ /\/ __(_) / /_\// /_/ / / | | GHC Interactive, version 6.3, for Haskell 98. / /_\\/ __ / /___| | http://www.haskell.org/ghc/ \____/\/ /_/\____/|_| Type :? for help.
Loading package base ... linking ... done. Loading package OpenGL ... ghc-6.3: can't load .so/.DLL for: GLU (/usr/lib/libGLU.so: undefined symbol: glPixelStorei)
I noticed that a similar problem has been discussed a while ago on the hopengl mailing list, and according to that thread, I found a solution, namely to edit ghc's package.conf file and to make sure that -lGL comes before -lGLU in extra_ld_opts. [...]
*sigh* This seems to be a NeverEnding Story (tm)... :-P It works fine on my SuSE x86 Linux (8.2 and 9.1) Just to be sure: What exactly does work and what doesn't on Gentoo? * Building an executable using OpenGL with GHC 6.2.1 * Calling ghci (6.2.1) with "-package OpenGL" * and the same two tests with the current CVS HEAD It would be good to know all 4 combinations. Meanwhile I'll try to dig out a few old emails on this topic. Differences like this even between two Linuxes are really annoying...
