[Boost-users] problems using serialization/export.hpp

I am having problems compiling the following file called save_a.cc.

#include "save_a.hh"
#include <string>
#include <fstream>
#include <boost/archive/text_oarchive.hpp>
#include <boost/archive/text_iarchive.hpp>
#include <boost/serialization/export.hpp>

BOOST_IS_ABSTRACT(space::A)
BOOST_CLASS_EXPORT(space::A)
BOOST_CLASS_EXPORT(space::B)
using namespace std;

namespace space {
void
save(const A* _a, const string& _filename) {
  std::ofstream ofs(_filename.c_str());
  OARCHIVE oa(ofs);
  oa & _a;
  ofs.close();
}

}

The errors that I get are as follows (I cut them off because they are
a lot of them):

Any idea what the problem is?

Thanks.
