Hi, I am trying to use the subgraph class with bundled propeties and wonder if it is still broken? I found a message on the list saying that it was broken in March 2005, but would probably be fixed shortly. I include my code below. It compiles cleanly if I don't use subgraph, i.e. just declare the adjacency_list. It also works if use the internal properties method. Thanks, Greg // ... appropriate headers using namespace std; using namespace boost; typedef unsigned long int uvid; struct VertexProperty { uvid gmr_number; vector<string> labels; }; struct EdgeProperty { std::size_t biconnected_component; vector<string> labels; }; typedef adjacency_list<setS, vecS, undirectedS, VertexProperty, EdgeProperty> GraphPlain; typedef subgraph< GraphPlain > Graph; int main(int argc, char* argv[]) { GraphPlain g1; Graph g; return 0; }
