Michael,
I think the fltk team have figured out a cross platform way of
including the OpenGL headers:
http://svn.easysw.com/public/fltk/fltk/tags/release-1.1.8/FL/gl.h
http://svn.easysw.com/public/fltk/fltk/tags/release-1.1.8/FL/glu.h
maybe we should adopt it?
I wonder where this OpenGL directory comes from or where it should be
placed? I searched my Mac for that OpenGL directory but couldn't find
it. I have used Apple's original GL framework, the headers are in
/usr/X11R6/include/GL and the libs can be accessed by '-framework
OpenGL'. There are no changes necessary from my point of view.
Somebody please posts the output from
bash~$ sudo find / -iname OpenGL
and
bash~$ sudo find / -iname gl.h
Thanks,
Thomas

as far as I understand
-framework OpenGL and -FOpenGL
on darwin are shortcuts for
-L/System/Library/Frameworks/OpenGL.framework/Libraries
and
-I/System/Library/Frameworks/OpenGL.framework/Headers
and from the apple gcc manpage
"An example include looks like "#include <Framework/header.h>", where
Framework denotes the name of the framework and header.h is found in
the "PrivateHeaders" or "Headers" directory."
so I beleive that
#include <OpenGL/gl.h>
includes
-I/System/Library/Frameworks/OpenGL.framework/Headers/gl.h
and indeed FL/gl.h from fltk uses the same include clause:
# ifdef __APPLE__
# include <OpenGL/gl.h>
# else
# include <GL/gl.h>
# endif
