If you want to do this, publish an interface in your C++ library with
the interface functions declared as extern "C"

C++ calling C++ is not portable because of name mangling. Other than
that, if you use the same compiler there is rarely any problem.

I would use an extern "C" interface, if I were in your shoes.
