[Mesa3d-users] Problem with de xdemo glsync

[Nicolas C. <nic...@ym...>]

Hello

I want to test the demo glsync (...\progs\xdemos\glsync.c) with the option -s b to use the verticale sync. 
The
problem is when the function glXSwapBuffer calls the function
GetGLXDRIDrawable(dpy, drawable, NULL), GetGLXDRIDrawable returns a
pointer(pdraw) which is NULL.

pdraw is NULL because psc->drawHash is NULL.

The function __glXInitialize(dpy) called from GetGLXDRIDrawable returns a display private wich already exists

I want to know why the drawHash structure is NULL and how to do to have a drawHash which is not NULL ?

Thanks
Nicolas Cadio
