you seem to be right.
I was using a header file for class declaration and a cpp file for
definition, when i moved everything to cpp file,
It worked.

But what is the problem? My header file contains
 template<class Archive>
    void serialize(Archive & ar, const unsigned int version);

and in cpp file
template<class Archive>
void g7GameObject::serialize(Archive & ar, const unsigned int version)
{
ar & height;
ar & width;
......
} // my class name is g7GameObject

and with above code i get following error
error LNK2019: unresolved external symbol "private: void __thiscall
g7GameObject::serialize....

What am i doing wrong
