Yeh, I have the same problem, and I have a FULL
install (all packages). ld can't link any glut calls,
so there's a Cygwin setup problem. Cygwin Opengl
package comes with gl, glu, glut headers, glut32.dll,
and libglui.a libgluix.a. There's no libglut.a. I
think that OpenGL is required by XWindow, so libGL.a
and libGLU.a exist in X11R6 lib path. glxgears works,
so gl works, but glut doesn't.

GHC for Win32 includes a kind of 'gcc' (some
executable and libraries). I supposse that GHC uses
this gcc, and not Cygwin's, so libraries and headers
are missing again: when you 'make' redbook_C examples,
cygwin gcc is used, but with redbook_HS GHC gcc is
used (I think). At the beginning of this topic Sven
points to a .zip containing Mingw OpenGL headers that
might be extracted on GHC path, but what about
libraries?

Manuel.
