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....

I am trying to implement very simple sample of boost serialization. I have a sample class, class1. It only contains a simple int variable. I followed the examples given here : http://www.boost.org/doc/libs/1_45_0/libs/serialization/doc/index.html
I also think that i followed this guideline : http://beta.boost.org/doc/libs/1_44_0/more/getting_started/windows.html but i am not sure...
Here is the error i get:

This is likely an error in your application. class1::serialize<...> is not defined in the library or the serialization headers. It's missing from your application. You've used something like
class1 c; ... ar << c
but there is no
classs class1 { ... template<class Archive> void serialization(Archive &ar, unsigned int version){ ... } ... };
