Linker errors.

[Carl Hjerpe]

Hello, i have a quite advanced project, its a wow server project. Anyways this is problems that probably have occurred to everyone: Linker errors.

Im getting these linker errors when i'm trying to compile git://github.com/Lillecarl/one.git (git checkout develop) to checkout to my development branch which does not always compile or work at all.

What im trying to do is having a vector (the only list like thing ive partly mastered) and storing a struct containing two values in there. Then find the player pointer via the players guid, accessing a set of files which is far beyond my knowledge. I only need help with the linker errors, and "workarounds" are not really interesting, because i never understood linker errors or their msdn explanations really. So i come here in hope of getting not only a clear answer of what i probably should include, but also why this is happening and how you actually found out how to solve this riddle. Any feedback is appreciated

EDIT: Seems like it's compiling on my Debian machine, but not my windows (VS2008) machine :S
