[Boost-users] boost::posix_time::time_period and boost::serialization

Subject: [Boost-users] boost::posix_time::time_period and boost::serialization
From: Lakin Wecker (lakin_at_[hidden])

I'm having some issues getting the following example to compile in 
g++4.9, or clang 3.6, using boost 1.58.0

I'm not quite experienced enough with boost or c++ to be certain, but it 
appears that the vector serialization is done in such a way that it 
doesn't pick up the load_construct_data for time_period from 
boost/date_time/posix_time/time_serialize.hpp

Is the fix simply to do my own vector serialization a situation like 
this? Or is there another fix?

Thank in advance,

Lakin

$ cat test.cpp

#include <boost/serialization/vector.hpp>

#include <vector>

class test
{
public:

     friend class boost::serialization::access;

     std::vector<boost::posix_time::time_period> m_vec;

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

int main(int argc, char *argv[]) {
     test a;

     std::ostringstream os;
     boost::archive::text_oarchive oa(os);
     oa << a;

     std::istringstream is(os.str());
     boost::archive::text_iarchive ia(is);
     ia >> a;

     std::cout << os.str() << std::endl;

     return 0;
}
