Hi there, I'm trying to draw a circle to a surface using sdl_gfx. I've compiled a .dll, an .a and a .lib of sdl_gfx myself succesfully (I thought). When I link my project to the libraries, i get errors at compile time as such:

e:/development/mingw/bin/../lib/gcc/mingw32/4.7.0/../../../SDL_gfx.lib(SDL_gfxPrimitives.o): In function `fastPixelColor':
E:\DEVELOPMENT\workspace\sdl_gfx\Debug/../SDL_gfxPrimitives.c:198: undefined reference to `_SDL_LockSurface'

and literally hundreds of them. I must have made an oopsie when compiling sdl_gfx or linking my own project to it.

Can anybody explain what I'm doing wrong here? I'm pretty sure this is caused by myself here.

Thanks in advance.

Okay, after a little reading into what a .dll, an .a and a .lib actually are I concluded the following: I never actually compiled a .lib file, just renamed the artifact to such. For some reason Eclipse really wants a .lib, though. Anyone can help me on how to make such a thing? thank you...
