Here is the full source code. Any suggestion? Thank
you very much!
Try the change below:

Robert Ramey
...
#include <iostream>
#include <sstream>
#include <fstream>
using namespace std;
#include 
#include 
class dd
{
private:
   friend class boost::serialization::access;
   template<class Archive>
   void serialize(Archive & ar, const unsigned int
version)
   {
       ar & i;
   }
int i;
};
class dummy
{
public:
   dummy() : d(0){}
   ~dummy(){}
private:
   friend class boost::serialization::access;
   template<class Archive>
   void serialize(Archive & ar, const unsigned int
version)
   {
//***  replace this:
...
//ar & const_cast
(d);
//*** with this
        //ar & const_cast
(d);
...
}
const dd *d;
};
int main()
{
   const dummy w;
   dummy r;
// make an archive
   std::ofstream ofs("dummy");
   boost::archive::text_oarchive oa(ofs);
oa << w;
std::ifstream ifs("dummy");
   boost::archive::text_iarchive ia(ifs);
ia >> r;
}
c:\Documents and
Settings\yccheok\Desktop\xxx\main.cpp(34): error
C2679: binary '&' : no operator found which takes a
right-hand operand of type 'dd *' (or there is no
acceptable conversion)
