Hey People, I'm having some issues using BOOST's serialization capabilities in version 1.53. To be honest, the capability provided by boost seem to involve a lot of macro usage here and there, and despite the fact that I've read a number of tutorials, I still don't feel like I've got a solid grasp on how it all works. Probably because I keep running into compilation problems that I can't seem to figure out how to fix logically, I usually just end up trying a number of different macro's that other people recommend until it just works. Not ideal, I know, but... All my logical deduction usually leads me to solutions that don't work as I keep expecting. Case in point, I want to serialize some data as XML. Essentially it's just a struct with a few strings in it that is used as 'settings' data. I get the following error message during compilation in VS2012: Error 47 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' d:\sdks\cinder\boost\boost\archive\basic_xml_iarchive.hpp 70 I found out, it had to do with any XML serilization requiring an additional 'name' to be added, pertaining to how XML works via the 'BOOST_SERIALIZATION_NVP' macro. I added that to all my strings - still nothing. Then I proceeded to comment out everything, so my struct is now just an empty shell: struct AEMSettings { // Superfluous since structs are fully public? friend class boost::serialization::access; AEMSettings() { } /*** * Serialize handles both input/output as the & operator doubles as both << and >> */ template<class Archive> void serialize( Archive &ar, const unsigned version ) { //ar & BOOST_SERIALIZATION_NVP( mSpeakersDeviceName ); //ar & BOOST_SERIALIZATION_NVP( mSpeakersDeviceDriverName ); //ar & BOOST_SERIALIZATION_NVP( mHeadphonesDeviceName ); //ar & BOOST_SERIALIZATION_NVP( mHeadphonesDeviceDriverName ); //ar & BOOST_SERIALIZATION_NVP( mMicrophoneDeviceName ); //ar & BOOST_SERIALIZATION_NVP( mMicrophoneDeviceDriverName ); } //std::string mSpeakersDeviceName; //std::string mSpeakersDeviceDriverName; //std::string mHeadphonesDeviceName; //std::string mHeadphonesDeviceDriverName; //std::string mMicrophoneDeviceName; //std::string mMicrophoneDeviceDriverName; }; Can anyone tell me what I am missing here?
