I have defined the following class that will hold configuration parameters read from a file and will let me access them from my program: class VAConfig { friend std::ostream& operator<<( std::ostream& Is this for testing / learning? Not the answer you're looking for? Extern Template Similarly, nodo_colaypila.cpp contains the implementations of the nodo_colaypila<...> classes.

Remember, when compiling cola.cpp, the compiler has no clue which instantiations will be needed; and we can't expect it to compile for every type in order to ensure this problem never Note that this time round I have not instantiated any object of type some_class at all.

That means no .cpp files.

If your compiler supports it, you can declare your template as "extern" and use it the way you would any other member, at the cost of additional link-time work.

Anyway, it makes sense to look at your test case. in the header file: template inline T* find_name(std::vector v, std::string name) { // ... } or explicitly instantiate the template in the .cpp where you've defined the template.

That means that we cannot separate the interface in a separate header file, and that we must include both interface and implementation in any file that uses the templates. at the end of the file).
