Hello, I'd like to save and restore a adjacency_list graph in a XML file, Does anyone has some example code or can help me? I can serialize std::map and others classes, but when I try to serialize the graph I get compiler errors. Thank for the help!! Camilo Some part of the code: #include #include #include #include #include #include typedef adjacency_list< vecS, vecS, bidirectionalS, no_property, no_property > Graph; template<class Archive> void serialize(Archive & ar, const unsigned int version) { ar & BOOST_SERIALIZATION_NVP(graph); } Error!!! C:\Boost\include\boost-1_35\boost/archive/basic_xml_oarchive.hpp(86) : error C2664: 'boost::mpl::assertion_failed' : cannot convert parameter 1 from 'boost::mpl::failed ************boost::serialization::is_wrapper<T>::* ***********' to 'boost::mpl::assert<false>::type' with [ T=boost::no_property ] No constructor could take the source type, or constructor overload resolution was ambiguous __________________________________________________ Preguntá.
