But what about boost::adjacency_matrix<boost::directedS>?

No, that too has to be boost::adjacency_matrix<boost::bidirectionalS>.

Unfortunately this doesn't help(

Where I can read your answer before I recieve e-mail?

Try <http://lists.boost.org/Archives/boost-users/>

I can see my post's here http://lists.boost.org/boost-users/2006/02/date.php but I can't reply on them(

Thanks for the reply. 2 Doug, Now I also can't use template <typename MutableGraph> bool read_graphviz(std::istream& in, MutableGraph& graph, dynamic_properties& dp, std::string const& node_id = "node_id") ; function for the same type. I think because of following declaractions in "adjacency_matrix.hpp" ////////////////////////////////////////////////// template <typename D, typename VP, typename EP, typename GP, typename A> inline typename adjacency_matrix<D,VP,EP,GP,A>::vertex_descriptor add_vertex(adjacency_matrix<D,VP,EP,GP,A>& g) { // UNDER CONSTRUCTION assert(false); return *vertices(g).first; } template <typename D, typename VP, typename EP, typename GP, typename A> inline typename adjacency_matrix<D,VP,EP,GP,A>::vertex_descriptor add_vertex(const VP& vp, adjacency_matrix<D,VP,EP,GP,A>& g) { // UNDER CONSTRUCTION assert(false); return *vertices(g).first; } template <typename D, typename VP, typename EP, typename GP, typename A> inline void remove_vertex(typename adjacency_matrix<D,VP,EP,GP,A>::vertex_descriptor u, adjacency_matrix<D,VP,EP,GP,A>& g) { // UNDER CONSTRUCTION assert(false); } //////////////////////////////////////////////////////////// Will it be also implemented or how I can read my graph?
