I have a class which has got the serialize function implemented.

template<class Archive>void myClassB::serialize( Archive& ar, const unsigned int)

Somehow, this function is skipped and doesn't appear even in the object file created for this file which gives me undefined reference errors later when linking.

I have included :

#include <boost/archive/text_iarchive.hpp> #include <boost/archive/text_oarchive.hpp> #include <boost/archive/binary_oarchive.hpp> #include <boost/archive/binary_iarchive.hpp>

In my cpp file.

Does this sound faimiliar to anyone? Or am I going wrong somewhere?

Function templates usually need to be defined in the header file. If you define it in the cpp file, you need to use explicit instantiation. In Christ, Steven Watanabe
