Panda crash on Fedora

General Discussion
1

Hello all, I am running into a very frustrating problem with Panda3D. I downloaded the RPM from here for Fedora 9 (64bit) and installed the package with no problem.
I was told that Panda was so easy to use, but I cannot even get the simplest program running.
I created a simple test file as suggested in the manual, the file only contains:

import direct.directbase.DirectStart
run()

but whenever I run this, the program crashes horribly. A window is briefly seen, opening and closing. This is what I get on the console:

$ python test.py 
DirectStart: Starting the game.
Warning: DirectNotify: category 'Interval' already exists
Known pipe types:
  glxGraphicsPipe
(all display modules loaded.)
:util(warning): Adjusting global clock's real time by 0.582924 seconds.

My python version is 2.5.1. I have the system updated to the latest available packages. Seems like there is a problem with glibc but what could it be, wrong version? The package in my system for glibc is version 2.8-8. Any suggestions are greatly appreciated.

I can bet my bottom dollar that the problem is OpenAL.
Try editing your /etc/Config.prc file, search for the line that contains “audio-library-name libp3openal_audio”, and replace the value with “libp3fmod_audio”.

I really thought I fixed this in 1.5.4.

Thank you! Surely enough the program now works. I get the grey window. I tried some other examples and they run too. The only problem is that I get errors on the audio now:

$ python test.py 
DirectStart: Starting the game.
Warning: DirectNotify: category 'Interval' already exists
Known pipe types:
  glxGraphicsPipe
(all display modules loaded.)
:audio(error): _system->init(): Error initializing output device.

:util(warning): Adjusting global clock's real time by 0.896807 seconds.
:util(warning): Adjusting global clock's real time by -0.021992 seconds.

I may need to tweak some the audio configuration, but at least the rest is working.

Oh, it just means Panda can’t initialize audio since some other application is already using it. Try shutting down all the applications using sound. (Shutting down pulseaudio works for me, too.)

I haven’t tried this, but should fix it :
