hi

 

I downloaded the newest source, and installed it.

I tried to start it with the green "run"-button in eclipse.

At first it works, but then an error occours:

Is this a forge bug or is it a bug of Linux? (I use Kubuntu 12.10)

Seems that it doesn't like your natives, try getting a fresh copy. Your os doesnt like loading the 32-bit version it seems...

[aligator123456]

hmm it is a fresh copy.

 

do you think I should use a 32-bit -java jdk?

I have done this already.

 

edit: I tried 32-bit java, but it doesn't work, too .  :'(
