I am trying to compile a simple glX/OpenGL program under Cygwin/XFree86. The building process is OK. But the glXChooseVisual always returns NULL at runtime. This program has been compiled under many UNIX environments and runs properly. I have changed the attributed array passed to glXChooseVisual many times, but it still does not work. I use the header files at /usr/X11R6/include and libraries of /usr/X11R6/lib/libGL.a and libGLU.a.
Cygwin/XFree86 does support OpenGL, right? Cound anyone send me a simple model OpenGL program which can be built and run under Cygwin/XFree86? Thanks a lot.
