Re: [Boost-users] Error using boost_serialization

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
