Yes, that is a nasty detail. the SIMVoleon lib (on Linux) needs the 
objects to be compiled with -fPIC. This is because on Linux all objects 
that go in shared libs need to be compiled with -fPIC.

Indeed, libSIMVoleon.a is not a shared lib you will say. The thing is, 
we put the objects from this lib into libSoOD.so . Thus, they still need 
to be compiled with -fPIC.

Thus, add -fPIC to the compile flags and this should work.
