[Boost-users] [Graph] How to initialize edge index map?

Hi,

How to initialize edge index map?
I tried following:

  typedef adjacency_list<vecS, vecS, directedS, Vertex, Edge>
graph_t;     
  graph_traits<graph_t>::edge_iterator ei, ei_end;

  graph_t graph(num_nodes);

......
adding edges    
......
  
  for(tie(ei, ei_end) = edges(graph); ei != ei_end; ++ei, ++index)
    put(edge_index, graph, *ei, index); 

But I always get a compilation error:

boost::put_get_helper<Reference, PropertyMap>&, K, const V&) [with
PropertyMap = boost::adj_list_edge_property_map<boost::directed_tag,

I really can't get through all these template parameters :(

Please, tell me how to initialize this map properly!

Thanks,
