I friend has been so kind to donate me a radeon 9800 so now I'm giving this card
a spin with the new opensource r300 dri support.
I've just tried SMC: http://www.secretmaryo.org/ and it segfaults. Doing a
traceback on the core shows that the crash happens deep in r300_dri.so.
Depending on what distro your on SMC is a bit of a pain to compile, because it
needs CEGUI. I've been involved in packaging cegui for Fedora and it is
available for fedora from fedora-extras. For other distros I don't know what the
You can get CEGUI from here:
CEGUI contains a couple of bugs, 1 if not using xcerces, another when running on
64 bit, I've put the patches we use in fedora for this here for you:
CEGUI in turn needs DevIL:
Which also contains a few bugs, patches once again are here:
Once you've got CEGUI compiled and installed, you need todo the following to get
SMC 0.98.1 to compile:
chmod +x autogen.sh configure
./configure ...... continue as usual
I'm running a fully up2date Fedora development branch (rawhide) x86_64 system.
So I've got pretty much the latest version of everything.
I'm a skilled C programmer and have a bachelor in electronics. I've written a
few kernel drivers and lots of userland code. I'm however totaly at loss when it
comes where to begin with debugging OpenGL / dri problems.
Please let me know what I can do to help debug this, compiling CVS versions
adding printf running it through a debugger etc, should all not be a problem.
Here is a traceback of the crash with mesa-debuginfo installed to also get you
the line numbers where things are happening:

Seems the crash happens in mesa swrast (software rasteriser) not in r300.
What is the exact version of mesa you using ? Could you try with cvs version.
AFAIK my version is 6.5 with a few patches:
[hans@shalem ~]$ rpm -q mesa-libGL --changelog
* Tue Jun 13 2006 Kristian Høgsberg <email@example.com> - 6.5-9
- Add mesa-6.5-fix-pbuffer-dispatch.patch to fix pbuffer marshalling code.
* Tue May 30 2006 Kristian Høgsberg <firstname.lastname@example.org> 6.5-8
- Bump for rawhide build.
* Tue May 30 2006 Kristian Høgsberg <email@example.com> 6.5-7
- Update mesa-6.5-texture-from-pixmap-fixes.patch to include new
tokens and change tfp functions to return void. Yes, a new mesa
snapshot would be nice.
* Thu May 18 2006 Mike A. Harris <firstname.lastname@example.org> 6.5-6
- Add "BuildRequires: makedepend" for bug (#191967)

- Use -MG for generating deps and some files aren't yet symlinked at
make depend time.
- Drop mesa-6.4.2-dprintf-to-debugprintf-for-bug180122.patch and
as these are upstream now.
- Drop mesa-6.4.1-texture-from-drawable.patch and add

- Widen libGLU glob.
- Reenable r300 driver install.
- Widen libOSMesa glob.
- Go back to patching config/linux-dri, add mesa-6.5-build-config.patch,
- Disable sis dri driver for now, only builds on x86 and x86-64.
I'll give mesa CVS a try.
I've tried to use CVS, but it currently won't compile:

You need a newer libdrm use drm from cvs or try to update the package of your
distribution and see if it compile.
Thanks for the libdrm hint, with that CVS does compile.
However CVS isn't exactly stable. Thats an understatement! With CVS mesa SMC
does run but terible slow while no software fallback messages are printed.
I tried to run glxgears after SMC to see if DRI was still operational and my
After a reboot I ran glxgears again and it worked, but it was choppy it did less
fps then usual (1500 with the 5.6 snapshot it does 2800) and the turning of the
wheels wasn't smooth.
Then I ran ppracer and that resulted in another hard crash, more about that in
my ppracer bug.
Good News! I've just tried smc again with the latest CVS, which I installed to
confirm that bug 7371 is fixed. With current cvs smc works, albeit still very
slow (software fallback), but now it does print a fallback message, the problem
is smooth lines, just like with google earth. By commenting the fallback in case
of smoothlines in r300_renderer.c I get descent performance with smc.
Very well done, keep up the good work!
This bug can be closed as far as I'm concerned.
Close the bug...
