Problem accessing private member of base class in friend class through derived object.

[Radhika Ganganna]

Hi,
 
I have a program that has a template base class with a private data member
in it.  It has a derived class. And both the base and derived class have a
common friend class. All these classes are part of a namespace. When I try
to access private data member of base class, through the derived class in
friend class, I get the following compilation error:  
 
Linux:/user/rgangann >gcc rad.cpp
rad.cpp: In member function `void radhika::friendclass::disp()':
rad.cpp:4: error: `char**radhika::Base<char*>::num1' is private
rad.cpp:17: error: within this context
 
The code is as below: 
 
namespace radhika {
template<class T> class Base { friend class friendclass; 
     private: T* num1; };
 
class Derived : protected Base <char * > { 
    friend class friendclass; 
    char ** num2; 
   };
 
class friendclass
{
  void disp(void)
  {
    Derived d;
    char**  a;
    a = d.num1;
  }
} ;
 
}; // End namespace radhika
 
int main()
{
        return 0;
}
 
 
I’m using gcc3.4.3. Let me know if this is an existing problem and how to
solve this problem. Also I find that when I do not have the classes in
namespace, the program works fine.

Radhika
