RE: gcc template error?

["Jason Mancini" <jayrusman@hotmail.com>]

I suspect this line is the source of your problems:
   friend T<class Y>* func<Y, X>(T<X>* p);
Y isn't a template parameter here, but a (concrete?) class named "Y".
The below compiles with 3.4.3 anyways...

// Line 1
class A {
public:
   A() { };
   ~A() { };
};


class B {
public:
   B();
   B(const A& a) { };
   ~B();
};


template <typename X, typename Y> class T;

template <typename X, typename Y>
T<X,Y>* func(T<X,Y>* p);


template <typename X, typename Y> class T {
   X*    m_;
public:
   T(X* x) : m_(x) { };
   ~T() { };
   friend T<X,Y>* func<X,Y>(T<X,Y>* p);
};


template <typename X, typename Y>
T<X,Y>* func(T<X,Y>* p) {
   return (new T<X,Y>(new X(*p->m_)));
}


int main() {
   A* a = new A();
   T<A,B>*    p = new T<A,B>(a);
   T<A,B>*    q = func<A, B>(p);
   return 0;
