ok.

hm, then I don't really see a reason why a call like
dGeomBoxGetLengths() fails...

Is your ODE compiled to use single or double precision floating point
numbers (this is selected with a preprocessor define -DdSINGLE or
-DdDOUBLE)? Since the OpenSG physics classes all use float, it should
probably be dSINGLE, perhaps a mismatch in these settings causes the
problem?
