Fantastic, works like a charm! I thought the problem was in the way I
was using SWIG but the culprit was the C/C++ linkage. Now I can try it
with my original files.
Thanks for all the help!

What you need to do is to surround the declaration of jonas_testv()
with en extern "C" {} declaration. If you don't do this, then the
linker is looking for the "mangled name" , which is C++'s way to embed
type declarations in a function name. If the function is declared in
the .h as extern "C", it will just expect the function name with an
underscore in front of it, just like C does.
