           Summary: cyclical dependency between libglx and libGLcore
           Product: xorg
           Version: 6.7.0
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Lib/GLX
        AssignedTo: xorg-bugzilla-noise at freedesktop.org

The glx module depends on a symbol in the GLcore module.  The GLcore module
depends on a symbol in the glx module.

I found at this URL http://www.gelato.unsw.edu.au/linux-ia64/0008/0441.html that
someone had already fixed the problem in the following way:

diff -urN XFree86-4.0/xc/programs/Xserver/GL/mesa/src/X/xf86glx.c

+__GLXcontext *__glXLastContext;

When I added the __GLXcontext *__glxLastContext; line to xf86glx.c and
recompiled, I had no problem loading the GLcore module.
