[Boost-users] [BGL] List of edges as property type

I'm trying to add a "list of edges" as an edge property type like so. typedef adjacency_list < listS, vecS, directedS > Traits; typedef adjacency_list < listS, vecS, directedS, vertex_properties,     property < edge_list_t, std::listTraits::edge_descriptor, edge_properties > > > graph_t; But the compiler says :  error: ‘edge_list_t’ was not declared in this scope So I think I need to add edge_list_t to the set of property tags. I think there is a method like BOOST_INSTALL PROPERTY ( edge_list_t ). But I think I read somewhere that thats the old way. Can someone tell me the new way to do it? PS: How can I tell which version of boost I am using? Thanks - Caligula
