Perhaps your sample dll does none of the problematic things
Reini mentioned. However, if a C++ vendor dll, built with
msvc, communicates through anything but a very restrictive
subset of C++ (only the vendor can tell you that), then it
can't be linked to code built with g++ to produce a valid
program. It's not just difficult: it's simply not feasible.

Here's another explanation:

Probably your only option is to use msvc.
