The problem here is that you are trying to mix to incompatible things: 1- libraries from the w32api package (-lglu32 -lopengl32) which are about displaying openGL graphics directly through a native Windows interface (Win32) without any X server; 2- some other librairies (-lX...) that are about displaying through an X server. Than cannot work. You must make up your mind: Either you follow the Win32 road and you move your discussion to cygwin at cygwin dot com (as Yaakov suggested). Or you follow the X server road. As OpenInventor is some SGI thing, it is probably the best choice. In that case, you should update all your X11-related packages (-L/usr/X11R6/lib is related to the old version). In particular, you will need the following packages: libGL-devel, libGL1, libGLU-devel, libGLU1, which are about displaying openGL graphics through an X server. In that case, keep the discussion at cygwin-xfree at cygwin dot com. - André Bleau, Cygwin's volunteer OpenGL package maintainer.
