Bugzilla Bug 135643

From the ebuild:

        amd64? (
                app-emulation/emul-linux-x86-xlibs
                || (
                        >=media-video/nvidia-glx-1.0.6629-r3
                        >=x11-drivers/ati-drivers-8.8.25-r1 ) )"

I'm using the r300 mesa driver, which I pull from CVS with an ebuild. When
updating world, portage pulls either nvidia-glx or ati-drivers, and I want
neither of those packages.

Possible solution(?):

- Update mesa (produce 32 bit libs on an amd64 multilib system) and x11-drm
(include a CVS snapshot of the r300 driver).
- Introduce a new virtual like "virtual/opengl32" which these (and future)
packages can provide.

This totally does not belong to us.  The ebuild is 100% correct for the current
state of the tree.  This really needs to be assigned to the X folks.  Also,
there's another bug somewhere (I can't find it right now) about r300 and 32-bit
MESA.  Once there actually *is* a multilib-friendly mesa ebuild, then this can
be changed by us.

The other bug for reference:

http://bugs.gentoo.org/show_bug.cgi?id=133727

If this is a mesa problem then it belongs to x11.

Chris, see below. Clientside dri modules means the 3d drivers, including r300.

  Bump with libs from xorg-7.0, include clientside dri modules (bug 115605) to
  better support 32bit opengl apps with oss drivers. Don't install opengl
  header files so as not to confuse eselect-opengl (bug 109922).

I have "fixed" this in CVS.  The only problem that I see now is that I have no
way of guaranteeing that someone has a compatible video card anymore.  I guess
I'll just have to wait for the flood of bugs from people with cards that don't
have 32-bit support yet.  ;]

Feel free to point bugs about this at me, I don't mind supporting the use of
open-source drivers. =)

I don't have a problem with it, either.  It was just that before it was pretty
simple.  You either had an ATI or NVIDIA card, and you used the binary drivers,
or it didn't work.  Now it'll just be a bit more ambiguous.

I'm sure there's aprobably a couple other ebuilds in the tree that need this
sort of working over, too.
