You cannot mix Visual C++ ("real" C++, I mean, not C) and Gnu C++ modules in any way whatsoever. The two have completely different class and virtual-table layout algorithms.

You can actually. g++ emulates the msvc vtable layout.
But you should not because of different underlying runtime libraries. new/delete mainly, but a lot of other dependencies clash also.


If you need to link a Gcc-compiled object to a VC++-compiled object, you can only use 'extern "C"' APIs (and C structures) to cross between the two.
