Is there any way to get more debugging information from glfwOpenWindow than 1 || 0? The problem is I am trying to run glfw on an X11 system and it simply doesn’t work. I can compile but the program fails to open a window. I am suspecting that I am missing a file: libXxf86fm.so.1 (I have libXxf86fm.a)

any suggestions?

The difference between [libXxf86vm.so](http://libXxf86vm.so).\* and libXxf86vm.a is irrelevant - it’s simply the difference between linking it in statically or as a shared library.

The error should be elsewhere.
