[Boost-users] serialization error for a struct

Hi all, I am very new to boost. I am getting a serialization error, and I have no idea about what to do #include <boost/serialization/string.hpp> //some other headers struct field { std::string field_name; std::string field_type; std::string field_ref; std::string field_colType; }; int main(int argc, char* argv[]){ vector<field> C; // other definitions // populating the C vector scatter(world, C, relMyValues, w_mySize, 0); } and I got error: struct field has no member named serialize what should I do? thank you in advance
