XFree86 DRI on SPARCstation5 (CG6 gfx)

Hi all,

after installing Gentoo 1.4_rc4 on a SPARCstation5 and successfully emerging XFree 4.3 (takes two and a half days to compile on a 170MHz machine), I am now trying to get DRI support working for SUN CG 6 (driver: suncg6) graphics. Everytime I call 'glxinfo' I get a Segmentation Fault and a short message saying that the "XFree-DRI" extension is not enabled. I checked my XF86Config but from what I found here in the Gentoo forums, everything seems to be okay with that. Also, XFree86.log says that it has loaded the DRI extension. What did I miss?!

This is a problem with xfree-4.3.xxx & glx on sparc: See topic 49500
on this forum and my progressive comments at bug#19776.

I hope you still have the build for xfree in /var/tmp/portage, because
to fix this you have to patch the source for libglx. and regenerate that
library, which will take a while. What I ended up doing looks like this:
ebuild /usr/portage/x11-base/xfree/xfree-4.3.0-r2.ebuild fetch compile install qmerge

Go into "/var/tmp/portage/xfree-4.3.0-r2/work/xc/lib/GL/glx" and fix
the source as described in the bug #19776 (Comment #8 )

make; cd ..; make

Now, "cd GL" (so you are in .../xc/lib/GL/GL), and just
cp libGL.so.1.2 /usr/lib/opengl/xfree/lib
(or something equivalent. You are fixing /usr/lib/opengl/xfree/lib/libGL.so)

Now, glxinfo, glxgears, and so on should work. I just ignore the
"DRI not enabled" warning: I get it with a CG6 on a Sparc20 and with
an Elite-3D on an Ultra-2 (but if I recall correctly, not with a Creator-3D
on the same Ultra-2). I don't remember if I ever figured out what it is
talking about, but I do not find it to be a useful message.

Hope this helps,
Regards,
Ferris

First of all, thank you for the quick reply. Unfortunately, I had to clean my /var/tmp/portage directory due to limited diskspace

. So for now I will not recompile X11. But I'll get back to fixing this problem in the near future.

Damn. I'm having exactly the same problem described, with an Elite3D. I checked the bug information, and it seems like I have to go got another 5h of X11 compilation :-(

Thanks for the information, though!
