Re: [Boost-users] Default weight map doesn't work for weighted grid graph in A-star search

It doesn't work with a filtered_graph.  Adding the following line:

boost::property_map::const_type fpm = get(boost::vertex_index, m_barrier_grid);

produces this error:

g++ -g -I/src/boost-trunk -Wall -Werror -O3   -c -o astar_maze.o astar_maze.cpp /src/boost-trunk/boost/graph/graph_traits.hpp: In instantiation of ‘boost::vertex_property_type<grid>’: /src/boost-trunk/boost/graph/filtered_graph.hpp:226:   instantiated from ‘boost::vertex_property_type’ /src/boost-trunk/boost/graph/properties.hpp:202:   instantiated from ‘boost::detail::vertex_property_map’ /src/boost-trunk/boost/graph/properties.hpp:251:   instantiated from ‘boost::property_map’ astar_maze.cpp:234:   instantiated from here /src/boost-trunk/boost/graph/graph_traits.hpp:226: error: no type named ‘vertex_property_type’ in ‘class grid’

Which is the same error I was seeing before inside the astar_search call. 

Could you please try this code and the astar_search call with r64035 from the trunk? -- Jeremiah Willcock
