Hope everyone is doing well. I'm having an issue with boost serialization. I have serialized a file on my ODroid U2 using Boost v1.53. I'm trying to deserialize the file on a computer which only has Boost v1.46; however, line 7 below causes the following error: CMyClass Exception thrown: unsupported version Code: 1 void CMyClass::enableDeserialize(std::string file, bool binary) { 2 filename = file ; 3 isBinary = binary ; 4 ifs = new std::ifstream(file.c_str()) ; 5 try { 6 if (isBinary) { 7 CMyClass::ib = new boost::archive::binary_iarchive(*ifs) ; 8 } else { 9 CMyClass::ia = new boost::archive::text_iarchive(*ifs) ; 10 } 11 } catch (boost::archive::archive_exception e) { 12 std::cout << "CMyClass Exception thrown: " << e.what() << std::endl ; 13 } 14 } The boost archive version for v1.53 (version I serialized with) is 10 and the boost archive version for v1.46 (the version I'm trying to deserialize with) is 9. Boost documentation hasn't helped me determine the differences between the 2 archive versions. I've only been able to find answers for how to deserialize an older archive. Please note, I don't do anything with BOOST_CLASS_VERSION. CMyClass hasn't changed at all. I can't imagine boost can handle the deserialization of a newer archive so I don't feel like I'm missing that answer. What I need to know if if there is a way I can serialize in v1.53 based on boost archive version 9 instead of 10. I'm hoping the new version of boost will still allow me to serialize at an older version. Then, I should be able to deserialize the archive just fine. Any advice you could provide is much appreciated! -- Lynn Coddington Gilbert Partner, Robotic Paradigm Systems www.roboticparadigmsystems.com www.facebook.com/RoboticParadigmSystems lynn@roboticparadigmsystems.com 678-428-0935
