Hi Jeremiah,

I tried putting the reverse_graph into a variable and then calling dijkstra with a weightma of the reversed graph as you suggested, but that results in a different error. I am having trouble understanding the error message I am getting from the compiler, could you please help me understand, what I am doing wrong?


Here is the supplementary code:

typedef reverse_graph<mcf_graph> reverse_graph_t;

reverse_graph_t rg = reverse_graph_t(g);

dijkstra_shortest_paths (rg, before_p, predecessor_map ( &p[0] ).distance_map ( &d[0] ).weight_map ( get ( &Edge::m_weight, rg) ).vertex_index_map ( get ( vertex_index, rg) ) );

And the error message

/usr/include/boost/graph/reverse_graph.hpp: In instantiation of ‘typename boost::disable_if<boost::is_same<Property, boost::edge_underlying_t>, typename boost::property_map<boost::reverse_graph<BidirectionalGraph, GraphRef>, Property>::type>::type boost::get(Property, boost::reverse_graph<BidirectionalGraph, GraphRef>&) [with BidirGraph = boost::adjacency_list<boost::vecS, boost::vecS, boost::bidirectionalS, Port, Edge>; GRef = const boost::adjacency_list<boost::vecS, boost::vecS, boost::bidirectionalS, Port, Edge>&; Property = double Edge::*; typename boost::disable_if<boost::is_same<Property, boost::edge_underlying_t>, typename boost::property_map<boost::reverse_graph<BidirectionalGraph, GraphRef>, Property>::type>::type = boost::detail::reverse_graph_edge_property_map<boost::adj_list_edge_property_map<boost::bidirectional_tag, double, double&, long unsigned int, Edge, double Edge::*> >]’:

Hi,

First of all thank you for providign the boost BGL library. I use it 
extensively.

I am having some problems with some code, that works just fine using boost 
version 1.46, but cannot compile using version 1.48 and higher.

I have a Bidirectional Graph using bundled properties defined as:

struct Port
 {
   Port(int index=-1, int type=-1, int port_code=0, string UN="NN", string 
name="NN", int service_id=-1 ): m_index(index), m_type(type), m_port_code( 
port_code), UNLOCODE(UN), m_name(name), m_service_id(service_id)  {}

   int m_index;
   int m_type;//0 port, 1 port call
   int m_port_code;
   string UNLOCODE;
   string m_name;
   int m_service_id;
 };

struct Edge
 {

 Edge( int id=-1, int type=-1, double weight=0.0, double cost=0.0, double 
dual_cost=0.0, double util=0.0, double cap=0.0, double r_cap=0.0 ) : 
m_idx(id), m_type(type), m_weight(weight) , m_cost(cost), 
m_dual_cost(dual_cost), m_utilization(util), m_capacity(cap), 
m_res_cap(r_cap)  {}

   unsigned int m_idx;
   int m_type;//0 is load edge, 1 is voyage edge, 2 forfeited edge 
(commodity link)
   double m_weight; //distance
   double m_cost; //cost - only on load/unload/transhipment edges
   double m_dual_cost;
   double m_utilization;
   double m_capacity;
   double m_res_cap; //residual capacity
 };



//Graph
typedef adjacency_list<
vecS ,
vecS ,
bidirectionalS,
Port,
Edge>
mcf_graph;

I am trying to make a call to dijkstra on a reversed graph as follows: (the 
reversed graph is also a filtered graph, but I do not think this is an issue:

dijkstra_shortest_paths (make_reverse_graph(fg), before_p, predecessor_map ( 
&p[0] ).distance_map ( &d[0] ).weight_map ( get ( &Edge::m_weight, fg) 
).vertex_index_map ( get ( vertex_index,fg ) ) );

The problem here is that you pass in a weight map from the original
graph while the algorithm expects one on the reverse graph.  That used
to work, but some of the internals of reverse_graph have changed so that
it doesn't anymore.  Try putting the reverse_graph into a variable and
then calling get(&Edge::m_weight, rg) on that.  You probably want to do
the same for vertex_index_map, but that is less important (reverse_graph
does not change the graph vertex type).
