Sometimes you have to use other compiler than VC++ (ok, be honest, in most cases 🙂 ), but what to do when your libs are in VC++ format? Solution is very easy, and it will be shown below on MySQL library case.
I assume you have mingw.
reimp.exe -d libmysql.lib
dlltool.exe -k -d libmysql.def -l libmysql.a
That’s all folks 🙂
