Comment (by anonymous):

 and a minimal example:

 #include <boost/shared_ptr.hpp>
 #include <boost/archive/polymorphic_text_iarchive.hpp>
 #include <fstream>
 #include <boost/serialization/shared_ptr.hpp>
 #include <boost/serialization/vector.hpp>//something to de-serialize
 int main(){
 std::ifstream i("foo");
     boost::archive::polymorphic_text_iarchive ia(i);
     boost::archive::polymorphic_iarchive & ia_interface = ia;
     boost::shared_ptr<std::vector<int> > p;
     ia_interface >> p;
 }

 boost version
 #define BOOST_VERSION 105700
