When I start glxgears(1) (on macppc) I see:
glxgears:/usr/X11R6/lib/modules/dri/r300_dri.so: undefined symbol
'drisw_create_screen'
libGL error: unable to load driver: r300_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: r300
I don't have a Radeon card on !macppc machine but on my amd64 I also
see:
$ nm /usr/X11R6/lib/modules/dri/r300_dri.so |grep drisw_create_screen
U drisw_create_screen
Sin the r300 and the r600 dri DSO are the same, I wonder if anybody is
able to load them?
$ ls -li r[36]00_dri.so
26355 -rw-r--r-- 2 root wheel 18913848 Dec 12 06:14 r300_dri.so
26355 -rw-r--r-- 2 root wheel 18913848 Dec 12 06:14 r600_dri.so
Diff below works for me. It clearly seems to be a workaround.
