Re: [Boost-users] [BGL] using biconnected_components with an exteriorproperty map

That doesn't compile, the definition of base_map generates an error whose explanation begins with: [..] So my question is: how can I make a call to biconnected_components in a manner that doesn't modify my graph (or any of its associated property maps)?

If you want to use external property map for edges, you must use edge_index instead of edge_descriptor. But, you must provide edge_index property by yourself. See exterior_properties.cpp for example. -- Regards, Janusz
