I have a class that is using a C struct, when I use the serialization code:

 

 

typdef struct A

{

     template <class Archive>

     void serialize( Archive & ar, )

     {

          ar & a1;

          ar & a2;

     }

     type1 a1;

     type2 a2;

}

 

I get error  A.h(59): error: this declaration may not have extern "C" linkage

   template<class Archive>

 

How can I archive this C structure which the class referenced?
