I try to use the Boost Graph library bundled properties which is introduced in 1.32.0. I modify the sample program libs/graph/example/graph_property.cpp which then fail to compile, I don't know enough about bundled properties to fix it. Please help. Thanks. I use gcc version 3.4.2 (Gentoo Linux 3.4.2-r2, ssp-3.4.1-1, pie-8.7.6.5). graph_property.cpp source code is: int main() { using namespace boost; using std::string; struct edgeStruct { int weight; }; typedef adjacency_list<vecS, vecS, directedS,no_property, edgeStruct, property<graph_name_t, string> > graph_t; graph_t g; get_property(g, graph_name) = "graph"; graph_t::vertex_descriptor v = *vertices(graph_t).first; graph_t::edge_descriptor e = *out_edges(v, graph_t).first; g[e].weight = 1; std::cout << "name: " << get_property(g, graph_name) << std::endl; typedef subgraph<graph_t> subgraph_t; subgraph_t sg; get_property(sg, graph_name) = "subgraph"; std::cout << "name: " << get_property(sg, graph_name) << std::endl; return exit_success; } //compile output is: gcc-C++-action
