Thread: Linking problems in Visual Studio

Hallo,

I have been stuggeling for a while now to get my project to work. I tried to add my Vector2D class to one of the others, but that turned out to create a lot of unforeseen problems.

I have #ifndef in front of all by header files, but this still happens. Any ideas on what I am doing wrong?

Here is what the evil compiler screams at me:
