Re: [Boost-users] [BGL] How to add a vertex_descriptor in a graph property

The constructor create a Vertex then defines root equal to that first vertex. But with bundled property I wanted to know if it is possible to define the root in the graph property. In fact I tried it but I am a bit embarrassed by the cyclic problem: - graph property needs to know what a vertex_descriptor is, - graph needs to know what a graph property is, - graph defines what a vertex_descriptor is.

I tried the Barton-Nackman trick but I failed.

Is it a proper way to do that ? Some advices, or pointers will be really apreciated.

Use adjacency_list_traits to get the vertex descriptor type: http://www.boost.org/libs/graph/doc/adjacency_list_traits.html Cheers, Doug
