Re: [Dri-devel] useful info for savage

[Alex D. <ag...@ya...>]

OT: XvMC, I've been playing with that today, but I can't seem to make
it build.  can you send me your imake file for the savageXvMC lib in
xc/lib/XvMC/hw/savage?  The one I have looks almost identical to the
one for i810 and yet it refuses to build.  Am I missing something?  do
I have to add it to some other imake for def file somewhere?
