It is due to different compilers. I don't know DirectX, but if it is 
C++, then it is related to name mangling. MSVC and GCC mangle names 
differently, that is mainly why C++ DLLs created by MSVC cannot be used 
by programs created by GCC, and vice versa. Remember the extern "C" ... 
stuff? It is needed to disable name mangling. Simple C DLLs and 
libraries can be used by both GCC and MSVC.

Your problem lies in different compilers, that's all.

The REAL trouble comes, when the import library is inconsistent with 
it's DLL. GCC tends to do this fairly often, and it has serious trouble 
exporting C++ classes. Linking to the import library for me doesn't 
always work, but when I link to the DLL directly (which luckily, GCC can 
do), everything is fine. This is odd, but again, this is what we have to 
live with.
