I have a problem with serialization in XML-format. The ser.routine saves the data as xml, but when trying to reload, the execution breaks. When using the text-output saving and loading works fine... I hope someone can help me: Here the code of the functions: ------------------------------------------------ main.cpp: ------------------------------------------------ #include "fixture.h" #include #include #include <iostream> #include <fstream> #include <string> #include <sstream> void save(CFixture* fixt, const char* filename) { ofstream ofs(filename); assert(ofs.good()); boost::archive::xml_oarchive oa(ofs); oa << BOOST_SERIALIZATION_NVP(*fixt); ofs.close(); } void load(CFixture* fixt, const char* filename) { ifstream ifs(filename); assert(ifs.good()); cout << filename << endl; boost::archive::xml_iarchive ia(ifs); cout << "Archive" << endl; ia >> BOOST_SERIALIZATION_NVP(*fixt); cout << "loaded" << endl; ifs.close(); } -------------------------------------------------- fixture.h: ------------------------------------------------- /* Header für Fixtures */ #include <vector> #include <string> #include #include #include #include #include class CFvalue { public: friend class boost::serialization::access; template<class Archive> void serialize(Archive & ar, const unsigned int version) { cout << "CFvalue" << endl; ar & BOOST_SERIALIZATION_NVP(min); ar & BOOST_SERIALIZATION_NVP(max); ar & BOOST_SERIALIZATION_NVP(name); ar & BOOST_SERIALIZATION_NVP(picture); } //...CUT...// class CFunctionvalues { protected: string svalue; int dvalue; int dvalue2; double pvalue; public: virtual bool setdvalue(int) = 0; virtual bool setdvalue2(int) = 0; virtual bool setpvalue(double) = 0; virtual bool setsvalue(const char*) = 0; virtual int getdvalue() = 0; virtual int getdvalue2() = 0; virtual double getpvalue() = 0; virtual string getsvalue() = 0; friend class boost::serialization::access; template<class Archive> void serialize(Archive & ar, const unsigned int version) { cout << "CFunctionvalue" << endl; ar & BOOST_SERIALIZATION_NVP(svalue); ar & BOOST_SERIALIZATION_NVP(dvalue); ar & BOOST_SERIALIZATION_NVP(dvalue2); ar & BOOST_SERIALIZATION_NVP(pvalue); } }; class CFunction : public CFunctionvalues { public: friend class boost::serialization::access; template<class Archive> void serialize(Archive & ar, const unsigned int version) { cout << "CFunction" << endl; ar & BOOST_SERIALIZATION_NVP(min); ar & BOOST_SERIALIZATION_NVP(max); ar & BOOST_SERIALIZATION_NVP(channel); ar & BOOST_SERIALIZATION_NVP(channel2); ar & BOOST_SERIALIZATION_NVP(has16bit); ar & BOOST_SERIALIZATION_NVP(type); ar & BOOST_SERIALIZATION_NVP(inverted); ar & BOOST_SERIALIZATION_NVP(name); ar & BOOST_SERIALIZATION_NVP(valuelist); ar & BOOST_SERIALIZATION_BASE_OBJECT_NVP(CFunctionvalues); } //...CUT...// class CFunctionset : public CFunctionvalues { protected: CFunction* base; public: friend class boost::serialization::access; template<class Archive> void serialize(Archive & ar, const unsigned int version) { cout << "CFunctionset" << endl; ar & BOOST_SERIALIZATION_BASE_OBJECT_NVP(CFunctionvalue); } //...CUT...// ------------------------------------------------- XML-Output ------------------------------------------------- <?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <!DOCTYPE boost_serialization> <*fixt class_id="0" tracking_level="0" version="0"> <channels>2</channels> <type>1</type> <name>MAX250</name> <manufacturer>GLP</manufacturer> <picture>max.jpg</picture> <functions class_id="1" tracking_level="0" version="0"> <count>2</count> <item class_id="2" tracking_level="0" version="0"> <min>0</min> <max>255</max> <channel>1</channel> <channel2>0</channel2> <has16bit>0</has16bit> <type>1</type> <inverted>0</inverted> <name>PAN</name> <valuelist class_id="3" tracking_level="0" version="0"> <count>2</count> <item class_id="4" tracking_level="0" version="0"> <min>0</min> <max>100</max> <name>links</name> <picture></picture> </item> <item> <min>101</min> <max>255</max> <name>rechts</name> <picture></picture> </item> </valuelist> <svalue></svalue> <dvalue>0</dvalue> <dvalue2>0</dvalue2> <pvalue>0</pvalue> </item> <item> <min>0</min> <max>255</max> <channel>4</channel> <channel2>0</channel2> <has16bit>0</has16bit> <type>3</type> <inverted>0</inverted> <name>COLOR</name> <valuelist> <count>3</count> <item> <min>0</min> <max>50</max> <name>White</name> <picture></picture> </item> <item> <min>51</min> <max>100</max> <name>Rot</name> <picture></picture> </item> <item> <min>101</min> <max>255</max> <name>Gelb</name> <picture></picture> </item> </valuelist> <svalue></svalue> <dvalue>0</dvalue> <dvalue2>0</dvalue2> <pvalue>0</pvalue> </item> </functions>
