Now we want to change some of its member fields to property, so we could use them in PropertyGrids. When we changed the class definiction to ref class X, we got a huge number of these compilation errors:

#1: error C2893: Failed to specialize function template 'boost::archive::text_oarchive &boost::archive::detail::interface_oarchive<Archive>::operator <<(T &)' d:\someAddress\someFile.cpp 58

#2: error C2784: 'std::basic_ostream<_Elem,_Traits> &std::operator <<(std::basic_ostream<_Elem,_Traits> &,const std::_Smanip<_Arg> &)' : could not deduce template argument for 'std::basic_ostream<_Elem,_Traits> &' from 'boost::archive::text_oarchive' d:\someAddress\someFile.cpp 58

We have a lot of tiny classes here, so it would be a pain to write a wrapper for each of them!

Here is the sample class we used:

ref class gps_position2


{
public:
    template<class Archive>


    void serialize(Archive & ar, const unsigned int version)





    {
        ar & seconds;
    }


public:
    gps_position(){};
    gps_position(float s)


    {
        this->seconds = s;


    }

    property float seconds;
};

And here is the main test code:

int main()


{
    std::ofstream ofs("out.txt");



    gps_position2 g(24.567f);

    // save data to archive


    {
        boost::archive::text_oarchive oa(ofs);


        // write class instance to archive
        oa << g;


    }
    // ................
    return 0;


}

Is it even possible to use boost::serialization with managed classes?
