That's a problem with the current Cygwin headers: They are simply lying, the DLLs under WinDoze only implement OpenGL 1.1 and GLU 1.2.2.
Mmm, but I think that my video card drivers replace this files.
That's not the case: The DLL is still 1.1, even in 2003. :-) All cool new stuff is available only via the OpenGL extension mechanism. As a start you can read e.g. http://www.opengl.org/developers/code/features/OGLextensions/OGLextensions.h...
I compile and install a module in Mandrake 9.0 for my Radeon 9000 and this is glxinfo output (under Linux):
Linux and most *nices are a bit different in this respect. The OpenGL libraries are normally 'real' 1.{2,3,4} ones, although the extension mechanism still works, too.
[...] Redbook_C examples work fine. But making Redbook_HS fails:

What version of GHC are you using? Upgrading to 5.04.2 could help here.
With WinXP + Cygwin + GHC neither C nor HS compile:
redbook_HS: ... h:\DOCUME~1\manuel\CONFIG~1\Temp\ghc1744.hc:844: `GL_UNSIGNED_INT_2_10_10_10_REV' undeclared (first use in this function)
Lying OpenGL headers again...
redbook_C: [...] Unable to link any GLUT functions. Maybe GLUT isn't properly installed...
Yes, that seems to be the case. The relevant line from your configure log: checking for library containing glutMainLoop... no I don't know what's wrong with your Cygwin setup. I've installed a fresh Cygwin a few days ago and everything is fine. I don't have a full installation, though, only the default stuff + development + graphics, IIRC.
GHC for Windows comes with some parts of GCC compiler, and I installed gcc for Cygwin also.
That's OK, the only trouble is that they sometimes see different headers.
Please I need some help, I must finish some work this week, Linux or Windows, GHC or Hugs.
Does HOpenGL-1.03 work with your Mandrake Linux? I'm developing on SuSE Linux, but there shouldn't be any differences. Cheers, S.
