Splitting templated C++ classes into .hpp/.cpp files--is it possible?

Question

I am getting errors trying to compile a C++ template class which is split between a .hpp and .cpp file:

$ g++ -c -o main.o main.cpp         


        

Answer 1

You can do it in this way

// xyz.h
#ifndef _XYZ_
#define _XYZ_

template 
class XYZ {
  //Class members declaration
};

#include "xyz.cpp"
#endif

//xyz.cpp
#ifdef _XYZ_
//Class definition goes here

#endif

This has been discussed in Daniweb

Also in FAQ but using C++ export keyword.
