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

I used boost::unordered_map for the A* output property maps. Since I'm also keeping track of a set of vertices to remove from the filtered graph, I tried implementing this with boost::unordered_set instead of std::set.  This doesn't build.  The error message is:

maze.cpp:243:   instantiated from here /src/boost-trunk/boost/graph/filtered_graph.hpp:60: error: no matching function for call to ‘set_contains(const boost::unordered_set, std::allocator >&, const boost::array&)’

What's going on is the vertex_subset_complement_filter calls is_not_in_subset, which calls set_contains in set_adaptor.hpp, which takes a std::set as its first argument.  Maybe you'd want to template this set type too.

Try r64026 -- unordered_set should work in that version. -- Jeremiah Willcock
