Try to call the mysql official provided by c + + API DLL is also collapse mysql_init (NULL);
What's the problem?

Give my feeling is that because of your MSVC and MinGW combination

General runtime collapse, is likely to be your environment and the DLL is not the same, or, maybe you is a 64 - bit app, and is a 32 bit DLL version
