I trying to compile a simple .c program that I
downloaded from sgi.com. I'm using the following to
compile the program (works on my UNIX box...):
gcc example.c -lglut -lGL -lGLU -L/usr/X11R6/lib -lX11
-lXmu -lm
I get a slew of compile errors, for every OpenGL api
call..For instance:
/cygdrive/c/DOCUME~1/XXXXXXXX/LOCALS~1/Temp/ccMTvQUj.o:example.c:(.text+0x2a):
undefined reference to [EMAIL PROTECTED]'
I noticed something a bit odd. The documentation
states that /usr/include/GL should contain the files:
glut.h and gl.h, but I ONLY have glut.h.

OpenGL is a bit confusing in Cygwin, because you can compile programs to
use Win32 WGL or X11 GLX as your OpenGL provider. This is a case of
using WIN32 libraries versus Cygwin libraries is useful, because GLUT
provides all of the OS-dependent interface.
The Win32 headers are in /usr/include/w32api (included by default?) and
are linked with -lOPENGL32. The X11 headers are under /usr/X11R6/include
and are linked with flags as you describe above.
