Hi,
How to initialize edge index map?
I tried following:
typedef adjacency_list
graph_t;
graph_traits::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:
/usr/include/boost/property_map.hpp: In function ‘void boost::put(const
boost::put_get_helper&, K, const V&) [with
PropertyMap = boost::adj_list_edge_property_map,
boost::edge_index_t>, Reference =
boost::detail::error_property_not_found&, K =
boost::detail::edge_desc_impl, V =
int]’:

I really can't get through all these template parameters :(
Please, tell me how to initialize this map properly!
Thanks,
Anton.
