Please take note that even the following simplest form
won't work.

Here is the full source code. Any suggestion? Thank
you very much!

#include <iostream>
#include <sstream>
#include <fstream>

using namespace std;

#include <boost/archive/text_oarchive.hpp>
#include <boost/archive/text_iarchive.hpp>

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)
    {
        ar & const_cast<dd *>(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)
