Dear all, I am using bundled properties when I define my graph. The bundled properties are smart pointers to my own class Edge and Vertex. I write something like: typedef boost::shared_ptr<Vertex> VertexPtr; typedef boost::shared_ptr<Edge> EdgePtr; typedef adjacency_list<vecS, vecS, directedS, VertexPtr, EdgePtr> Graph; Vertex and Edge being my own classes to store information on the vertices and the edges. For what I read in the doc, this is the correct, more modern way to do it. My problem is the following. I am trying to use the BGL algorithms and some of them require vertex/edge info to be provide as properties maps. From http://www.boost.org/doc/libs/1_41_0/libs/graph/doc/bundles.html I know it is possible to generate those maps from bundled properties. It works well if I don't use shared_ptr but cannot compile otherwise. When using shared_ptr, similarly to the doc, I wrote: typedef property_map<SearchGraph, float EdgePtr::*>::type WeightMap; WeightMap weightMap = get(&EdgePtr::m_cost, *_graph); m_cost being a public float member of my own class Edge. I have the following compilation error: 'm_cost' : is not a member of 'boost::shared_ptr<T>' Indeed it is not. My question is, I can let the shared_ptr access the member? In other world how to deal with bundled properties / properties maps and shared_ptr. Extra question, could 'm_cost' be a private member of my own class Edge? Thank you very much Sincerely, Damien
