I'm using SDL and it's working fine, but now i'm trying to implement the SDL_gfx library. I downloaded it, extracted it, and put all the header/cpp files into a shared library project in CB and built it. In the release folder there were three files: libSDL_gfx.dll, libSDL_gfx.dll (A File), and libSDL_gfx.dll (Export Definition File).

I put the first into the SDL bin folder, next to SDL.dll. the second in the SDL lib folder next to libSDLmain and libSDL.dll. the third one i didn't do anything with. I then took all the header files that came with the download and put them in my SDL include folder.

When I compile, it works, but when I try to use a function from the library (pixelRGBA) i get the error: undefinded reference to 'pixelRGBA'

I'm quite sure I did something horribly stupid. Could someone tell me where I went wrong? Thanks.

I've done that.

Link libraries:
SDL_gfx.dll

Search Directories -> Linker:

C:/SDL/lib

Did I build the library wrong?

oBFusCATed:
Remove .dll in SDL_gfx and try again.

Also check with a tool capable of reading dlls if the missing symbols are in your library.
One such tool is dependency walker.

I strongly suggest turning on full compiler logging

Note: With some linker options the order of options matter.
