Fixed bug #232 ------- Comment #2 From Matthias Geissert 2006-05-24 07:54 [reply] ------- See http://dri.sourceforge.net/doc/DRIuserguide.html, section 11.5. There is written that you need to use RTLD_GLOBAL, since, otherwise, nested open of dynamic libraries doesn't work. However, This is necassary in this case, since libGL opens the hardware-specific driver/library. I hope this helps you.
