[Boost-users] BGL: boost::astar_search_no_init

Hi there! Currently i try to implement an astar search with BGL and boost. My graph is infinite, so i searched for an example of astar_search_no_init and found this: http://lists.boost.org/boost-users/2012/03/73707.php I am on gcc-4.9.0 and boost 1.52.0 on linux. I try to compile the above example and get the following error which i cant decipher ... make gcc -std=c++11 example.cpp -o example example.cpp: In function 'int main(int, char**)': example.cpp:274:140: error: no matching function for call to 'boost::associative_property_map, unsigned int> >::associative_property_map(default_map, unsigned int>)' . weight_map(boost::associative_property_map,unsigned>

(default_map,unsigned>(1)))

I added the code as an attachement. For me it seems that this line is not ok .... but i currently have no clue how to fix it ... try { astar_search_no_init(g, start, distance_heuristic<XYGraph>(goal) , visitor(astar_goal_visitor(goal)) . distance_map(d) . predecessor_map(boost::ref(p)) . weight_map(boost::associative_property_map,unsigned>

(default_map,unsigned>(1)) // < --- line 274 . vertex_index_map(boost::associative_property_map (std::map())) . rank_map(boost::associative_property_map (std::map())) .

color_map(boost::associative_property_map<std::map<XY,boost::default_color_type> >(std::map<XY,boost::default_color_type>())) . distance_compare(std::less<unsigned>()) . distance_combine(std::plus<unsigned>()) );

with clang 3.4 i get this error line. clang --std=c++11 example.cpp -o ex example.cpp:274:26: error: no matching conversion for functional-style cast from 'default_map, unsigned int>' to 'boost::associative_property_map, unsigned int> >' . weight_map(boost::associative_property_map,unsigned>

(default_map,unsigned>(1))

So what ant the author of this code do? Allocate a property map of size 1? Currently i dont see the forrest, there are so many trees in my view .... Any help would be appreciated! Thank you! Georg
