Ok thanks that helped. Now I got another problem. I can't put the std::ostream& *operator*<<(std::ostream& os, const ResData& rD){ *return* os << rD.getResName() << rD.getSeqNum() << rD.getInsNum() << rD.getSAS(); } in ResData.h because that results in multiple definition errors. But when I put it in ResData.cpp I get the following error: /usr/include/boost/serialization/access.hpp:109: undefined reference to `void ResData::serialize<boost::archive::text_oarchive>(boost::archive::text_oarchive&, unsi how do I get around this problem? thanks again, Sebastien Gerega Vladimir Prus wrote:

You need to use
const ResData& work_around = temp; oA << temp;
For 1.33, Robert decided that you can't save non-const objects like this. Many objected, but we failed to persuade him.
