Hi,

I have installed new Kubuntu 8.04, recompiled libavg, that I had before up and running on 7.10, compilation seemed to be OK, and make install also went ok, make check gave an error:

Is this libavg 0.7 or an older svn version?

yes 0.7 one

In any case, you seem to be running into an older stderr/opengl driver issue that is described here:

https://www.libavg.de/wiki/index.php?title=Libavg_on_Debian_etch_installation_notes

Look under 'Broken stderr workarounds'.

I looked to it and just tried this MALLOC_CHECK, will try other workaround too
I updated libavg from SVN, compilation went ok, and install went ok, make check gives this:

...
GraphicsTestSuite succeeded.

This is a test for code I'm heavily working on at the moment. It's not used in libavg playback yet, so you can just comment it out. However, it would be nice to have a stack trace so I can make it more stable :-). I assume the stack trace in the next mail is for the first segfault?

yes, the first segfault, do you want to look  at trace for this (testgpu)?
(I tried MALLOC_CHECK_=0 - result is the same)

This concerns the first crash, right? The testgpu crash won't be affected by MALLOC_CHECK_. If so, you can try one of the othe workarounds on the web page I gave above.


yes, the first crash
Cheers,
