Hi, I want to create hierarchy of property maps like this: #include <boost/graph/adjacency_list.hpp> #include <boost/property_map/property_map.hpp> using namespace boost; struct Base_NodeP { int basic_property; }; struct NodeP : public Base_NodeP { // using Base_NodeP::basic_property int derived_property; }; int main(){ typedef adjacency_list<setS, vecS, undirectedS, property<vertex_index_t,int,NodeP>, no_property> TGraph; property_map<TGraph, int NodeP::*>::type _basic_property; property_map<TGraph, int NodeP::*>::type _derived_property; TGraph tgraph; _derived_property = get(&NodeP::derived_property, tgraph); _basic_property = get(&NodeP::basic_property, tgraph); return 0; } When I compile this code in MSVS 2008, I'm getting error C2679: binary '=' : no operator found which takes a right-hand operand of type 'boost::bundle_property_map<Graph,Descriptor,Bundle,T>' (or there is no acceptable conversion). gcc 4.3.2 gives similar error: error: no match for ‘operator=’ in ‘_basic_property = boost::get [with OutEdgeListS = boost::setS, VertexListS = boost::vecS, DirectedS = boost::undirectedS, VertexProperty = boost::property<boost::vertex_index_t, int, NodeP>, EdgeProperty = boost::no_property, GraphProperty = boost::no_property, EdgeListS = boost::listS, T = int, Bundle = Base_NodeP](&Base_NodeP::basic_property, ((boost::adjacency_list<boost::setS, boost::vecS, boost::undirectedS, boost::property<boost::vertex_index_t, int, NodeP>, boost::no_property, boost::no_property, boost::listS>&)(& tgraph))) When I uncomment "using Base_NodeP::basic_property" in NodeP declaration, MSVS is happy, but gcc still cannot compile the code. Do you have any suggestions, how can I make this code work under gcc? Am I doing something wrong?
