Hi, snipped below gives this error in VS 2008 SP1: Error 1 error C2664: 'void boost::container::vector<T>::priv_range_insert<InIt>(Object **,FwdIt,FwdIt,std::forward_iterator_tag)' : cannot convert parameter 4 from 'boost::detail::iterator_category_with_traversal' to 'std::forward_iterator_tag' c:\devel\boost_1_47_0\boost\container\vector.hpp 1908 copy_range code: #include #include #include <functional> class Object; struct DecodeID : public std::unary_function { Object* operator() (int id) const { return 0; } }; int main() { using namespace boost; using namespace boost::container; using namespace boost::range; vector<int> ids; vector objects = copy_range

(adaptors::transform(ids, DecodeID())); }

Am I missing something obvious here?
