friend class is in none-namespace

Hi,

I'm looking for a solution with friend concept. The friend class is out of the namespace. It isn't in any namespace. So, is there a solution?

Code:

---

namespace b
{

        class Test
        {
                public:
                        friend class Test2;
                        ~Test(){};
                private:
                        Test(){};
        };


}; // end namespace b

class Test2
{
        public:
                Test2(){};
                ~Test2(){};
                void test()
                {
                        b::Test* t = new b::Test();
                };

};

int main(){
        Test2 t;
        t.test();
        return 0;
}

---

Ouput:
main.cpp: In member function ‘void Test2::test()’:
main.cpp:11: error: ‘b::Test::Test()’ is private
main.cpp:24: error: within this context

Thank you very much for your time.

greetings

Hello there
you need to make the friend declaration visible outside the namespace.
When you use new in C++, you must call delete, or else you have a memory leak.

..and um namespace doesn't end with a semi-colon :)
