Hi,
I’m running hardy 8.04, with a standard python 2.5.2.
I installed the newest panda from the i386 deb, and pview works fine, but
when trying to run the python samples i get:
DirectStart: Starting the game.
Warning: DirectNotify: category ‘Interval’ already exists
Known pipe types:
glxGraphicsPipe
(all display modules loaded.)
*** glibc detected *** python: double free or corruption (out): 0x088bf100 ***

Hi,
Could you maybe add this line to the top of /etc/Config.prc:
notify-level debug(replace “debug” with “spam” to spit out even more debug info)
And give us the last few lines of the output?
Thanks for the quick reply, here’s what i got with debug:
grzes@toshi:/usr/share/panda3d/samples/Looking-and-Gripping$ python Tut-Looking-and-Gripping.py
DirectStart: Starting the game.

I didn’t know exactly which lines are goiing to tell you something so i cut most of the repetitive stuff…
Ah. This appears to be a bug in Panda3D; it accidentally got configured to use OpenAL instead of FMOD. I’ll put it on the bug list for 1.5.4.
To fix this, you just need to find this line in your /etc/Config.prc:
audio-library-name p3openal_audioChange that into:
audio-library-name p3fmod_audioYou can also remove the notify-level line you just added.
I’ll bet my bottom dollar that it will work now. 
If not then there might be something wrong with the heron build. I had problems with it segfaulting on me so I switched to the gibbon build.
The heron build came from me too, so err, if you have further problems with it, I’ll be over there doing me some hara-kiri. 
awesome, worked like a charm thanks so much.

Greg
