sorry, the previus message is eronneous.

the right code is

#include <iostream>

#include <boost/archive/text_oarchive.hpp>
#include <boost/archive/text_iarchive.hpp>
#include <boost/serialization/vector.hpp>
#include <fstream>

class A
{
  public:
  A(){}

  private:
  //Serialization tasks
  friend class boost::serialization::access;
  template<class Archive>
  void serialize(Archive & , const unsigned int )
  {

  }
};

int main()
{
   std::vector<A> eig;
   std::cout <<eig.size()<<std::endl;
  std::ofstream of("file.txt");
  {
    boost::archive::text_oarchive oa(of);
    oa << eig;
  }
  of.close();
  std::ifstream ifs("file.txt");
  {
    boost::archive::text_iarchive ia(ifs);
    ia >> eig;
  }
  std::cout <<eig.size()<<std::endl;

   return 0;
}
