This is an omission (bug) in the BGL. If you change your graph type
to this:
typedef boost::adjacency_list<
boost::setS, // Adjacency list
boost::setS, // Vertex list
boost::undirectedS, // Undirected graph
unsigned int, // Vertex property (unique label)
boost::no_property, // Edge property
boost::property<boost::graph_name_t, unsigned int>, //
Graph property (next unique label)
boost::listS // Edge list
> graph;
You can get at the graph property with:
get_property(graph_instance, boost::graph_name())
We'll find a better way to handle this in the next Boost release.
