First thing: there are 2 ways to use OpenGL and GLUT under Cygwin: through an X server and natively. As you ran it under Unbutu, I suspect you use the X server, but please confirm it. I cannot deduce anything from your stackdump. Some applications have configure script to build with an X server on Linux and natively on Windows. If your application goes for the native route, my package (the opengl package) is concerned and I will try to help you further. In that case, you may uninstall the other packages mentionned above to clear any possible (but improbable) confusion. Try some simple program first: see if one of the native GLUT example programs run properly: /usr/lib/glut-examples/helloGlut.exe , then /usr/lib/glui-examples/example6.exe . If they work, try rebuilding them by going to /usr/share/doc/opengl-1.1.0/GLUTexamples and /usr/share/doc/opengl-1.1.0/GLUIexamples and typing "make". If your application goes for the X server route, I will let the maintainers of the related packages take you from here. You may uninstall the opengl package to clear any possible (again improbable) confusion. X related issues should be discussed on a separate list: cygwin-xfree at cygwin dot com . > > Thanks, > > Nathan > HTH, André Bleau, Cygwin's OpenGL package maintainer Please send any questiopn or comment about the OpenGL package to cygwin at cygwin dot com, not directly to me.
