problem of template inheritance on g++

[amol]

Following is the code which works on windows but can't work with g++ 
 

template < class  my_type>

class mytypedef
 {
            public :
                        typedef my_type  new_type;
};

 

template <class my_type>

class sample: public mytypedef < my_type >

{

            public :

                        new_type var;

};

 

Error : new_type doest not name a type.

 

Why is it happening?

What is solution for this problem?
