The error LNK 2001 is either because you're missing the implementation of those functions or the definition of those variables.
To solve this, check that you have implemented those functions and defined those variables.

The error LNK 2005 is because the linker is findind 2 implementations for the same function and can't decide which one is the one that should be using. To solve this check that you have only one implementation for each function.

Hope this helps
