Description Pavel Ondračka 2010-10-15 09:29:22 UTC

I usually configure mesa like this: "--enable-debug --enable-gallium-radeon --with-dri-drivers= --with-state-trackers=dri,glx", with this HoN starts and runs fine with r300g driver. However I was trying llvmpipe with some other apps and I noticed, when I add "--enable-gallium-llvm", HoN won't start with "K2 - Fatal Error: ARB_vertex_buffer_object not available." 
This is quite strange because glxinfo is identical and shows GL_ARB_vertex_buffer_object in both cases (and OpenGL vendor string: X.Org R300 Project, OpenGL renderer string: Gallium 0.4 on RV530, so its not like I was using some other driver). I'm quite sure I didn't messed up anything I even asked at #radeon if I'm doing something wrong. LIBGL_DRIVERS_PATH and LD_LIBRARY_PATH are both pointing to right mesa directories and I did git clean -fdx between builds. 

So far I wasn't able to reproduce this with any other app.

This is with Fedora 14 i686, kernel 2.6.35.6-39.fc14, mesa from git, RV530.

So either the game is picking up a different libGL.so.1 / r300_dri.so, or the error message is misleading and the problem is due to something not visible in glxinfo. As a starting point, are there any differences in the output of 'glxinfo -l'?

The only difference in 'glxinfo -l' output is mesa build time.

Comment 3 Pavel Ondračka 2010-10-22 09:12:09 UTC

Now I found another app which have problems with --enable-gallium-llvm. With Unigine Sanctuary I get this crash. But it works fine when compiled without --enable-gallium-llvm.

X Error of failed request:  BadLength (poly request too large or internal Xlib length error)
  Major opcode of failed request:  117 (X_GetPointerMapping)
  Serial number of failed request:  27
  Current serial number in output stream:  29

Comment 4 Marek Olšák 2010-12-09 19:09:01 UTC

I've been running Mesa with --enable-gallium-llvm all the time and I don't have this issue.

Comment 5 Marek Olšák 2010-12-14 09:42:13 UTC

export LIBGL_DEBUG=verbose

and run HoN. Does it print anything interesting?

Comment 6 Pavel Ondračka 2010-12-15 03:32:30 UTC

with LIBGL_DEBUG=verbose:

Comment 7 Pavel Ondračka 2010-12-15 03:36:58 UTC

When I remove libstdc++.so.6 bundled with HoN it works fine... so probably not a mesa bug after all.
