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

Another possibility is to do something like:

#ifndef _STACK_HPP
#define _STACK_HPP

template 
class stack {
    public:
            stack();
            ~stack();
};

#include "stack.cpp"  // Note the include.  The inclusion
                      // of stack.h in stack.cpp must be 
                      // removed to avoid a circular include.

#endif

I dislike this suggestion as a matter of style, but it may suit you.
