I already answered this, what was not clear from my previous post?

For your example code there is nothing special about how g++ handles
templates.  Some other compilers can handle templates in the way you
want but they do so in a non-standard way.  G++ conforms to ANSI/ISO
standard (mostly) so will not compile your code.

You need *TWO* files only: foo.h & main.cpp

// foo.h
template<class Etype>
class Foo
{
public:
  void Replace();
};

// ALSO IN foo.h  <----- *** THIS IS WHAT YOU ARE MISSING ***
template<class Etype>
void Foo<Etype>::Replace()
{}


// main.cpp
#include "foo.h"

int main()
{
  Foo<int> hi;
  hi.Replace();
}


And compile with:

gpp -Wall -W main.cpp -o main
