I have created a template class with its implementation in a .cpp file and its declaration in a .h Compilation finishes successfully and i get errors during linking with unresolved externals. The reported externals are methods of the template class. If i put the implementation of these methods in the header file, after the declaration of the template class then everything goes fine. What could be wrong. I have the feeling that it could be something really easy that i'm missing at the moment.

In the header is where they are supposed to be. The compiler can't compile the implementations of the template class's member functions for different template parameters unless it can see the source code for the functions at all the places the template is used.
