true. You only need to include headers which describe the features of the
library that you actually use.  Many applications will compile build and run
with:

#include <boost/archive/text_iarchive.hpp>
#include <boost/archive/text_oarchive.hpp>
#include <boost/serialization/base_object.hpp>

The very first line of the tutorial says

"An output archive is similar to an output data stream. Data can be saved to
the archive with either the << or the & operator"

I think that, along with the example, that should be pretty clear.

This suggests the appropriate serialization library has not been included in
the link step.  Have you in fact built the boost libraries.  That is, have
you run bjam with "stage" ?

Have you been able to build and run one of demo applications - for example
demo.cpp ?
