Здравствуйте.

class trn

private:
    friend class boost::serialization::access;

    int    id;
    std::string    name;

    template<class Archive>
    void serialize(Archive & ar, const unsigned int version)
    {
        ar & BOOST_SERIALIZATION_NVP(id);
        ar & BOOST_SERIALIZATION_NVP(name);
    }

public:
    trn(){};
    trn(int id_, std::string name_) : id(id_), name(name_) {};
};

int _tmain(int argc, _TCHAR* argv[])
{
    trn a1(1, "test");

    std::ofstream ofs("1.xml");

    {
        boost::archive::xml_oarchive oa(ofs);
        oa << a1;
    }
    return 0;
}

Вот такая вот бяка...хотя с тестовой и бинарной сериализацией — все на ура проходит. Это читал и не понял....с серализацией в бусте не очень — так что если не трудно — поможите
