I guess its a good thing that I am about to take a class in template metaprogramming, becuase I have just found out it has to be one of the weaker points in my programming part of my brain. I just can't seem to squash this linker bug. I'm getting an unresolved externals for a template method: The core.hpp file does include the library.hpp too. Here's the linker error: Anyone have any ideas? Thanks a head of time.I guess its a good thing that I am about to take a class in template metaprogramming, becuase I have just found out it has to be one of the weaker points in my programming part of my brain.
