The fglrx driver libraries are under /usr/lib/fglrx I think and the actual libGL.so.x.x is probably in one of the sub-directories. Look also in /usr/lib/X11. > Is your OS is ubuntu too?

OSG wouldn't compile correctly if you didn't have the libraries installed. However, do make sure that you don't have a messed up installation, linking OSG to e.g. the libGL from Mesa (software driver). That wouldn't work right. Please make sure to follow these instructions and install the driver properly: https://help.ubuntu.com/community/BinaryDriverHowto/ATI The part "2. Installation via the Ubuntu repositories" should be sufficient. Regards, Jan
