Ok, I know I've been here before with template problems, and now I need
specific help again to understand how templates work in DJGPP (G++). Here is
my code:

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


***foo.C
#include "foo.h"

template<class Etype>
void Replace()
{}

***main.C
#include "foo.h"

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


And I get the error on the compilation of the executable:
:main.C: undefined reference to `Foo<int>::Replace(void)'

Now, my question is what SPECIFICALLY would I need to change to make gpp
compile it properly? In otherwords, how would I have to re-write the code to
make it work? Please be as speciffic as possible.

Thanks again,
Al Combs
