Re: Unable to run webots 5.1.1 (linux ubuntu breezy)

Hi,

I have tested Webots on a third Linux machine (Celeron 1100, SIS 
graphics card, Debian 3.1 - Mesa 4.0.4), I installed both gcj and 
classpath on this machine, as well as sun jdk 1.5.0_06, but roboka.wbt 
still works perfectly (slow, but ok)... It's an interesting cue that it 
works as root user, but unfortunately, it gives me no immediate idea... 
Or maybe it's related to file access... Could you delete the file 
/usr/local/webots/resources/java.policy and tell me whether that 
helps?... Could you tell me if you can start java from the command line 
as a normal user?

I will send you a C-based replacement for Roboka0 to test (and also to 
Bothari).

If anyone on the list experienced a similar problem I would be curious 
to gather as much details as possible.

Thanks.

-Olivier
