Thread: friend question

i want to make class A friend of class B, so when i declare an instance of A within B its private members will also in handy. but things go wrongly when i compile it, my code is right below:

Code:

template <class T>
class A
{
	friend B<T>;
	public:
		//
	private:
		T data;
};
template <class T>
class B
{
	public :
		//
	private:
		A<T>* a;
}

i just can not figure out the problem, any ideas ?

btw, i am with Dev-C++ 5, thanx.
