Great, thanks. I added -fPIC as you did and everything went fine.
I tried so many combinations with and without -findirect-dispatch and with and 
without -fjni which all had more problems. I never thought about the 
-Wl,-Bsymbolic -fPIC line which I copied from the classpath wiki where it 
expalins how to compile a native eclipse.

Thanks for the good work!
