I am currently using an old SuSE version 8.x. Maybe it´s a version problem 
with the shared libraries you compiled it for and the shared libraries I 
have. That´s why I tried to compile Breve on my own. I have an other pc with 
Suse 9.0 I will try if it will work there. Searching google for this message 
I just encountered a lot of java stuff. I try to get deeper into it.

Yes, I think the same. That´s why I am currently compiling a new ode version. 
I hope it will work.

Usually we are using zthread but I think this is based on the pthread library.

I will try my very best to find the error. I´ll report you back if I found it. 
I thought that someone maybe encountered the same problems.
