It shows Linking error for the member functions of class. But when I remove template from Class the program runs well; even when I write all code (Class with template) in single "Program01.cpp" File then also it runs well.
Then what might be the problem in the above code?

// In AClass.h
template < class T >
class AClass
{
    int ATemplateFunction( T aObj );
};
 
// Don't define this function in AClass.cpp but in AClass.h
template< class T >
int AClass< T >::ATemplateFunction( T aObj )
{
   // Have fun
   return 1;
}

But I am creating Library ('Wind32 Static Library') using that code, so i can't write implementation of class in .h file.
So what should i do?
