Hallo I have currently installl the Boost boost_1.38 . Start new program in VC2003 add following lib in my project boost_serialization-vc71-mt-1_38.lib boost_serialization-vc71-mt-gd-1_38.dll example code: #include <boost/archive/text_oarchive.hpp> #include <boost/archive/text_iarchive.hpp> #include <iostream> #include <fstream> #include <stdio.h> using namespace std; void save() {   std::ofstream file("archiv.txt");   boost::archive::text_oarchive oa(file);   int i = 7;   oa << i; } void load() {   std::ifstream file("archiv.txt");   boost::archive::text_iarchive ia(file);   int i = 0;   ia >> i;   std::cout << i << std::endl; } //========================================================== /// Main function //========================================================== void main(int argc, char* argv[]) {     save();     load(); } After executing this example "archiv.txt" only stores 22 serialization::archive 5 instead of 22 serialization::archive 5 1 Could someone help me where i am making mistake??
