Re: [gentoo-powerpc] Radeon 3D powerpc

I have succesfully applied and installed mesa with the patch.
I needed to do the following

move the ebuild to my overlay /usr/local/portage/media-libs/mesa

then run the follwoing commands
ebuild pathtoebuild digest
ebuild pathtoebuils fetch
ebuild pathtoebuild unpack
then manuall apply patches
ebuild pathtoebuils compile
ebuild pathtoebuild install

how ever I an still not getting 3D. The only difference I am seeing is that
in Debian i needed to install linux-frimware-nonfree and I do not have that
option in gentoo.

rican-linux@ibookG4-gentoo ~/Desktop $ LIBGL_DEBUG=verbose glxinfo |grep
render
