Hi, I use an undirected graph with bundled properties and want to find out, whether it is connected, or not. Reading the documentation and some examples using property maps, I did not succeed in getting it to work. A minimal example that reproduces the compile errors follows. What am I doing wrong here: #include #include <vector> #include <iostream> // for std::cout #include <algorithm> // for std::for_each #include // for boost::tie #include // for boost::graph_traits #include #include using namespace boost; struct Node { int index; }; struct Boundary { double something; }; typedef boost::adjacency_list< boost::setS, boost::listS, boost::undirectedS, Node, Boundary, boost::setS> Graph; int main(int argc, char*argv[]) { Graph g(5); boost::graph_traits<Graph>::vertex_iterator vi, viend; std::vector<int> c(num_vertices(g)); int num; // manually intialize the vertex index, // because we have listS as vertex list type int n = 0; for (tie(vi, viend) = vertices(g); vi != viend; ++vi, ++n) { g[*vi].index = n; } num = connected_components(g, make_iterator_property_map(c.begin(), get(&Node::index, g), c[0])); return 0; } compile log: Compiler: Default compiler Executing g++.exe... g++.exe "Y:\graph\boost\test2.cpp" -o "Y:\graph\boost\test2.exe" -I"C:\Dev-Cpp\lib\gcc\mingw32\3.4.2\include" -I"C:\Dev-Cpp\include\c++\3.4.2\backward" -I"C:\Dev-Cpp\include\c++\3.4.2\mingw32" -I"C:\Dev-Cpp\include\c++\3.4.2" -I"C:\Dev-Cpp\include" -L"C:\Dev-Cpp\lib" C:/Dev-Cpp/include/boost/property_map.hpp: In member function `R boost::iterator_property_map::operator[](typename boost::property_traits<IndexMap>::key_type) const [with RandomAccessIterator = __gnu_cxx::__normal_iteratorboost::default_color_type > >, IndexMap = boost::adj_list_vertex_property_map, boost::detail::error_property_not_found, const boost::detail::error_property_not_found&, boost::vertex_index_t>, T = boost::default_color_type, R = boost::default_color_type&]': C:/Dev-Cpp/include/boost/property_map.hpp:319: instantiated from `void boost::put(const boost::put_get_helper&, K, const V&) [with PropertyMap = boost::iterator_property_map<__gnu_cxx::__normal_iteratorboost::default_color_type > >, boost::adj_list_vertex_property_map, boost::detail::error_property_not_found, const boost::detail::error_property_not_found&, boost::vertex_index_t>, boost::default_color_type, boost::default_color_type&>, Reference = boost::default_color_type&, K = void*, V = boost::default_color_type]' C:/Dev-Cpp/include/boost/graph/depth_first_search.hpp:197: instantiated from `void boost::depth_first_search(const VertexListGraph&, DFSVisitor, ColorMap, typename boost::graph_traits<G>::vertex_descriptor) [with VertexListGraph = boost::adjacency_list, DFSVisitor = boost::detail::components_recorder >, boost::bundle_property_map, void*, Node, int>, int, int&> >, ColorMap = boost::iterator_property_map<__gnu_cxx::__normal_iteratorboost::default_color_type > >, boost::adj_list_vertex_property_map, boost::detail::error_property_not_found, const boost::detail::error_property_not_found&, boost::vertex_index_t>, boost::default_color_type, boost::default_color_type&>]' C:/Dev-Cpp/include/boost/graph/depth_first_search.hpp:246: instantiated from `static void boost::detail::dfs_dispatchboost::detail::error_property_not_found::apply(const VertexListGraph&, DFSVisitor, Vertex, const boost::bgl_named_params&, boost::detail::error_property_not_found) [with VertexListGraph = boost::adjacency_list, Vertex = void*, DFSVisitor = boost::detail::components_recorder >, boost::bundle_property_map, void*, Node, int>, int, int&> >, P = boost::detail::components_recorder >, boost::bundle_property_map, void*, Node, int>, int, int&> >, T = boost::graph_visitor_t, R = boost::no_property]' C:/Dev-Cpp/include/boost/graph/depth_first_search.hpp:324: instantiated from `void boost::depth_first_search(const VertexListGraph&, const boost::bgl_named_params&) [with VertexListGraph = boost::adjacency_list, P = boost::detail::components_recorder >, boost::bundle_property_map, void*, Node, int>, int, int&> >, T = boost::graph_visitor_t, R = boost::no_property]' C:/Dev-Cpp/include/boost/graph/connected_components.hpp:93: instantiated from `typename boost::property_traits<IndexMap>::value_type boost::connected_components(const Graph&, ComponentMap) [with Graph = Graph, ComponentMap = boost::iterator_property_map<__gnu_cxx::__normal_iterator >, boost::bundle_property_map, void*, Node, int>, int, int&>]' Y:\graph\boost\test2.cpp:38: instantiated from here C:/Dev-Cpp/include/boost/property_map.hpp:349: error: no match for 'operator+' in '((const boost::iterator_property_map<__gnu_cxx::__normal_iteratorboost::default_color_type > >, boost::adj_list_vertex_property_map, boost::detail::error_property_not_found, const boost::detail::error_property_not_found&, boost::vertex_index_t>, boost::default_color_type, boost::default_color_type&>*)this)->boost::iterator_property_map<__gnu_cxx::__normal_iteratorboost::default_color_type > >, boost::adj_list_vertex_property_map, boost::detail::error_property_not_found, const boost::detail::error_property_not_found&, boost::vertex_index_t>, boost::default_color_type, boost::default_color_type&>::iter + boost::get [with PropertyMap = boost::adj_list_vertex_property_map, boost::detail::error_property_not_found, const boost::detail::error_property_not_found&, boost::vertex_index_t>, Reference = const boost::detail::error_property_not_found&, K = void*](((const boost::put_get_helper, boost::detail::error_property_not_found, const boost::detail::error_property_not_found&, boost::vertex_index_t>
