I'm on Solaris 2.6, GHC 5.02.3. Thank you for good work! Some quick notes:
1. examples/redbook_HS/Clip dumps core :(
A quick look with ddd revealed that GHC's RTS has a bug in alloca resp. allocaBytes: It must return a pointer with the *strictest* alignment, which is 8 bytes on SPARC for 64-bit integrals/floats. Currently, the returned pointer has only an alignment of 4 bytes. :-(
2. ghci -package HOpenGL doesn't work as shipped, but I've managed to make it work. First, ghci seems to need HOpenGL.o, not libHOpenGL.a. HOpenGL.o can be made with this command: ld -r -o HOpenGL.o */*.o in the lib directory.
Well, using HOpenGL with the current GLUT toolkit interactively doesn't make that much sense (mainLoop never returns). Anyway: With a newer ghc-pkg, the above ld stuff could be done automatically during the --add-package, IIRC, but I was reluctant to make the installation process (even more :-} fragile...
Second, I've moved libraries from extra_ld_opts section to extra_libraries section in HOpenGL.conf.
Hmmm, this doesn't work if there are options different from "-lfoo", which is the case at my site: Configure determines that the options "-L/usr/openwin/lib" and "-R/usr/openwin/lib" must be used here, too. Thanks for your encouraging report! :-) Cheers, S.
