c++ custom container compilation error

Question

I am trying to write a container as

 template <typename T, typename A = std::allocator<T> >    
 class circular_dlist{
     ....
     public:

     class iterator{ 
       ....
     };

     void insert(T& val);
 };

In .cpp file when I define insert() method as:

template <typename T, typename A = std::allocator<T> > 
void circular_dlist<T, A>::insert(T& val){
}

I get following error:

error: default template arguments may not be used in function templates without -std=c++11 or -std=gnu++11

What is the correct syntax for defining function outside class definition in such cases if I am not using c++11?

You almost certainly don't want it in a `.cpp` file. http://stackoverflow.com/questions/495021 — Mike Seymour, Feb 27 '14 at 05:10
@MikeSeymour Thanks for pointing out .. I think I should move implementation to .h — sap, Feb 27 '14 at 05:15

Write simply

template <typename T, typename A> 
void circular_dlist<T, A>::insert(T& val){
}
