Oops - Looks like a check got missed. Change the top of device.c to add:that won't be sufficient. In my case, I do have glext.h but I don't have glxext.h. Sounds like we need some further check (configure, GL versions ...) for glxext.h
#ifdef HAVE_GL_GLEXT_H <--- Add this
#include <GL/glext.h> #endif <---- and this
#include <GL/glxext.h>
Note the #include <GL/glxext.h> may need to go inside the #ifdef.
A+
