Thank you very much. But I cannot compile it:

/usr/include/c++/3.2/bits/stl_iterator_base_types.h:123: no type named
`iterator_category' in `class boost::shared_ptr<A>'
/usr/include/c++/3.2/bits/stl_iterator_base_types.h:125: no type named
`difference_type' in `class boost::shared_ptr<A>'
/usr/include/c++/3.2/bits/stl_iterator_base_types.h:126: no type named
`pointer' in `class boost::shared_ptr<A>'
/usr/include/c++/3.2/bits/stl_iterator_base_types.h:127: no type named
`reference' in `class boost::shared_ptr<A>'

Do you know, what's wrong here?
