I am using boost 1.40.0. Reverse_graph.hpp seems to be missing the following function template <class BidirectionalGraph, class GRef> typename graph_traits<BidirectionalGraph>::vertex_descriptor vertex(const typename graph_traits<BidirectionalGraph>::vertices_size_type n, const reverse_graph<BidirectionalGraph,GRef>& g) { return vertex(n, g.m_g); } currently calling the function vertex (someIndex, reversegraph) returns an error. -- View this message in context: http://old.nabble.com/Missing-function-%27vertex%27-from-reverse-graph-tp263...
