Hello, I am looking for some help in following instructions to create a wide character archive that I found from the boost serialization documentation: Actually the reason I am on this path is because my code is crashing if I try to do this in a normal way. (please see my previous post [Serialization] Strange crash with binary_iarchive)
To produce wide character text output (i.e. 16 bit characters on Win32 systems), do the following.
Open a wide character stream. Alter the stream locale to use boost::archive::codecvt_null<OStream::char_type> Create the archive with the flag no_codecvt. Naturally, the input process has to be symmetrical.
My attempt (below) crashed when the archive is read back - what am I doing wrong? std::wofstream bofs("gps.bin", std::ios::binary); std::locale loc(bofs.getloc(), new boost::archive::codecvt_null<wchar_t>()); bofs.imbue(loc); // create class instance const gps_position g2(36, 60, 24.567f); boost::archive::binary_woarchive oa(bofs, boost::archive::no_codecvt); oa << g2; bofs.close(); cout << "reading archive..." << endl; gps_position newg; // create and open an archive for input std::wifstream ifs("gps.bin", std::ios::binary); std::locale loc2(ifs.getloc(), new boost::archive::codecvt_null<wchar_t>()); ifs.imbue(loc2); // CRASHES NEXT LINE boost::archive::binary_wiarchive ia(ifs, boost::archive::no_codecvt); // read class state from archive ia >> newg; The serialized class is below: #include <string> #include <vector> #include <fstream> #include <boost/archive/binary_oarchive.hpp> #include <boost/archive/binary_woarchive.hpp> #include <boost/archive/binary_iarchive.hpp> #include <boost/archive/binary_wiarchive.hpp> #include <boost/serialization/base_object.hpp> #include <boost/archive/codecvt_null.hpp> using namespace std; class gps_position { private: friend class boost::serialization::access; // When the class Archive corresponds to an output archive, the // & operator is defined similar to <<. Likewise, when the class Archive // is a type of input archive the & operator is defined similar to >>. template<class Archive> void serialize(Archive & ar, const unsigned int version) { ar & degrees; ar & minutes; ar & seconds; } int degrees; int minutes; float seconds; double* data; public: gps_position(){}; gps_position(int d, int m, float s) : degrees(d), minutes(m), seconds(s) {} }; Thanks Mahesh
