Hi,

I'm new to C++ and now I'm trying to learn how to use templates.

I've written the following three files.

[CSTACK.H]
#ifndef CSTACK_H
#define CSTACK_H

template <class stackType>
class cStack {
public:
  cStack();
  int push(stackType element);
};
#endif CSTACK_H

[CSTACK.CC]
#include <iostream.h>
#include "cstack.h"

template<class stackType>
cStack<stackType>::cStack()
{
  cout << "Constructed" << endl;
};

template <class stackType>
int cStack<stackType>::push(stackType element)
{
  cout << "Pushing..." << endl;
  return 0;
};

[TESTSTCK.CC]
#include "cstack.h"

int main ()
{
  cStack<int> int_stack;

  int_stack.push(12);

  return 0;
}

When I try to compile it using DJGPP 2.01 (based on gcc 2.7.0.1) I think I
get the following two errors:

undefined reference to cStack<int>::cStack(void)
undefined reference to cStack<int>::push(int)

How do I fix this? I've read something in info about GCC neither supporting
the Borland model nor the C/C++ frontend (or something) but I don't
understand how to fix it. 

	Dennis!
