Re: [Vala] undefined reference to 'SDL_Init' and/or 'WinMain 16' (under Windows)

Ehm, perhaps I can't use Visual Studio dependencies with MinGW.

I've downloaded these packages :
http://www.libsdl.org/release/SDL-devel-1.2.15-VC.zip

Perhaps I should download (gasp, =__= I didnt notice..)
http://www.libsdl.org/release/SDL-devel-1.2.15-mingw32.tar.gz

I'll try and keep you informed ;) (I need to clean my vala install..)
