[Boost-users] Dijkstra example

I tried to modify this example: http://www.boost.org/doc/libs/1_34_0/libs/graph/example/dijkstra-example.cpp to create the graph in a clearer fashion: http://codepad.org/DDKs45oe However, I now get compiler errors inside dijkstra_shortest_paths.hpp Can anyone see where I have gone wrong? Also, I don't really understand the "distances and parents" output - I just want to know the shortest path between two vertices. In fact I don't even see the start and end vertices specified in the original example? Thanks, David
