Alternatively, you might want to consider expanding the shared_ptr interface with enough information to permit serialization to be implemented via the public interface.
How, exactly? The current public interface is good enough for my serialization/deserialization needs, but I'm willing to consider your suggestions.
Do you remember out discussion on the subject.

I still believe We dont need any modification in shared_ptr to make it serializable (even more I believe it's evil od request one). I don't remember ever your answer on my last post.
evil to REQUEST a modification - wow. Don't even look at the hack I had to do - I might get the death penalty! I thought about a little more. If I rememeber correctly the essense of the problem during de-serialization was: template<class Archive, class T> void serialize(Archive &ar, shared_ptr<T> & t){ T * raw_ptr; ar >> raw_ptr; t = shared_ptr(raw_ptr); // problem is here - not matched with other shared pointers that might point to raw_ptr // current shared_ptr implementation depends upon an internal pointer to a shared count. } Attempts to resolve this all ended up re-implementing some aspect of the serialization library. I didn't really consider modifying the library to expose the relevant aspects IT'S implementation. That would entail much more than changing a private to public or adding a friend. As far as I was concerned - implementing the the library once was enough. The implementation I made is straight forward and is compatible with all aspects of the serialization library including exported pointers, pointers to polymorphic base classes, non-default and private constructors - everything. So maybe we can consider a practical compromise. a) Grant me access to the internals of shared_ptr for now b) When someone comes up with more satisfactory implementation of serialization of boost::shared_ptr and its passes a mini-review - the current one can be deprecated and the new one can be used.
