I need to see the linker command; the "mingw32-g++.exe -Wall  -g" means that is the compiler command or you have a very very messed up Code::Blocks configuration.

NOTE: you did NOT do something stupid like remove the include statement needed to get the code to compile, did you?

Please fix your code so it compiles; then post the link command.

Edit: Going to sleep; I suggest trying another forum; hopefully one that supports your SDL library.

Thanks a bunch for the help though. And yeah I probably did do something stupid...

Jenna:
And think about name mangling, if you probably use C-libraries with C++-code.

Radek:
You are getting compiler errors, not linker errors. The problem is not related to your DLLs, at least, so far. A header with "pixelRGBA" declaration has not been found. Check your (project) include path, whether it contains needed headers. Check whether the needed header is present. Also, get rid of those 234 warnings.

Linker errors (which are usually related to missing DLLs, missing libraries or unexpected kind of name mangling) are the complaints of "unresolved reference" or "duplicate reference" in compiled files (*.obj or *.o, not in *.cpp).
