Cross compiling DLL

Hello Everyone,
I'm trying to build a plugin by cross compiling from linux to windows
using mingw. The Linux version compiles and works, and the Windows
version compiles but gives me errors when it tries to load. I made a
test dll with the same code for the windows dll and it loaded fine
(errored missing purple_init)plugin) which leads me to believe my
windows dll stuff is correct.
Does anyone have any ideas? any way I can troubleshoot this?
