What I am doing wrong?


You must build MySQL++ with the exact same compiler and compiler options as you're using to build your program. What you're seeing is a name mangling and/or ABI mismatch due to mixing compilers and/or build options. This can be anything from a drastic error like trying to use a Visual C++ DLL with MinGW, to something more subtle like trying to use a MinGW DLL built with g++ 3.4.5 in a program you're building with MinGW g++ 4.4.

Unlike C, C++ doesn't try to preserve binary compatibility between greatly different compilers.


You probably have a linker issue. It could well be that a DLL you need isn't present, or mysql++ was compiled but not correctly linked.
