Already defined in .obj

[JimmyFo]

Hi, I'm getting a really frustrating error I can't get rid off. It reads like:

Fickleton error LNK2005: "public: void __thiscall world::removeGoal(class goal)" (?removeGoal@world@@$$FQAEXVgoal@@@Z) already defined in Gameworld.obj

There are 25 errors, 24 of which are 2 occurences of class functions like the ones above, then one final that says:

Fickleton fatal error LNK1169: one or more multiply defined symbols found

I only have three files, because I've been trying to compress the files to get rid of this error to no avail. I have a main cpp file which includes only: windows.h, gl/gl.h, and a custom cpp file. This cpp file has #ifndef/#define/#endif statements in it and includes only my custom header. This is ALSO covered with #ifndef/#define/#endif statements and includes only vector, stdlib, and using namespace std.

What is wrong with this picture?

Are you also linking the object generated by the custom .cpp file? If so, you have 2: one in main.cpp and one by itself.
