I would love to test xvmc on an intel chipset, but something is wrong.
I updated my source xorg tree using the git-xorg script (Now 1.9G in
total). It now has an xvmc folder in the xf86-video-intel/src/ folder.
I followed the instructions on the Xorg wiki and used the
But the intel driver build fails in configure, with...:
checking whether gcc and cc understand -c and -o together... yes
checking for intel-gen4asm... no
./configure: line 20441: syntax error near unexpected token `XINERAMA,'
./configure: line 20441: `XORG_DRIVER_CHECK_EXT(XINERAMA, xineramaproto)'
The problem appears to be that XINERAMA is not defined.
BTW this is the master branch, but I took it that the xvmc changes had
been committed to the master branch. I did not try pulling the xvmc branch.
Can anyone help?
