Hi everybody, I'm having deep troubles with the serialization library. I need to serialize a class (called VisualisationObject3D), but every time I try to serialize it I get a static compile error boost::STATIC_ASSERTION_FAILURE<x> referring to the line: oa << _obj (below you find the error stack and the source code). Since the error has to do with the tracking I tried disabling the trackin also, but without success. CAN SOMEBODY HELP ME? thanks in advance, Mauro. ------------------------ SOURCE CODE ------------------- class VisualisationPoint3D; class VisualisationObject3D { public: VisualisationObject3D(); ~VisualisationObject3D(){} std::vector<VisualisationPoint3D> m_vPoints; } void send_3D_object(VisualisationObject3D* _p){ tcpserialize::serialize_with_boost_to_socket<VisualisationObject3D>(_p,g_socket); } template<class T> bool serialize_with_boost_to_socket(const T* _obj, StreamSocket* send_socket){ std::strstream ss; { boost::archive::text_oarchive oa(ss); /*ERROR*/ oa << _obj; } char* _serialized_data=ss.rdbuf()->str(); size_t _serialized_data_size = ss.rdbuf()->pcount(); ...... return true; }; BOOST_CLASS_TRACKING(VisualisationPoint3D, boost::serialization::track_never) BOOST_CLASS_TRACKING(VisualisationObject3D, boost::serialization::track_never) namespace boost { namespace serialization { template<class Archive> void serialize(Archive & ar, VisualisationPoint3D & o, const unsigned int /* version */) { ar & ....; } template<class Archive> void serialize(Archive & ar, VisualisationObject3D & o, const unsigned int /* file_version */){ ar & .....; } } // namespace serialization } // namespace boost ------------------------ ERROR ------------- the error stack is here attached: d:\boost_1_33_1\boost\archive\detail\oserializer.hpp(567) : error C2027: Verwendung des undefinierten Typs "boost::STATIC_ASSERTION_FAILURE<x>" with [ x=false ] d:\boost_1_33_1\boost\archive\detail\oserializer.hpp(567): Siehe Verweis auf Instanziierung der kompilierten Klassenvorlage 'boost::STATIC_ASSERTION_FAILURE<x>' with [ x=false ] d:\boost_1_33_1\boost\archive\basic_text_oarchive.hpp(78): Siehe Verweis auf Instanziierung der kompilierten Funktionsvorlage 'void boost::archive::save(Archive &,T & )' with [ Archive=boost::archive::text_oarchive, T=const VisualisationObject3D * ] d:\boost_1_33_1\boost\archive\detail\interface_oarchive.hpp(78): Siehe Verweis auf Instanziierung der kompilierten Funktionsvorlage 'void boost::archive::basic_text_oarchive<Archive>::save_override<T>(T & ,int)' with [ Archive=boost::archive::text_oarchive, T=const VisualisationObject3D * ] h:\SHARED\UNDER_REPOSITORY_CONTROL2\TEST_PROGRAMS\NetworkManagerDll\network-tools\tcpserialize.h(122): Siehe Verweis auf Instanziierung der kompilierten Funktionsvorlage 'Archive &boost::archive::detail::interface_oarchive<Archive>::operator <<(const VisualisationObject3D & )' with [ Archive=boost::archive::text_oarchive, T=VisualisationObject3D ] h:\SHARED\UNDER_REPOSITORY_CONTROL2\TEST_PROGRAMS\NetworkManagerDll\NetworkManager.cpp(46): Siehe Verweis auf Instanziierung der kompilierten Funktionsvorlage 'bool tcpserialize::serialize_with_boost_to_socket<VisualisationObject3D>(const T *,tcpserialize::StreamSocket *)' with [ T=VisualisationObject3D ]
