Hi Aaron, Sorry for the absence of data. :) If I comment out the line: boost::planar_face_traversal(g, &planar_embedding[0], vis); the code compiles and runs smoothly. Otherwise, I get the following error messages: /home/helano/Desktop/temp/extrpg.cpp:79: instantiated from here /usr/include/boost/property_map.hpp:351: error: no match for ‘operator+’ in ‘((const boost::iterator_property_map<__gnu_cxx::__normal_iterator<std::map<long unsigned int, boost::detail::edge_desc_impl<boost::undirected_tag, long unsigned ... /home/helano/Desktop/temp/extrpg.cpp:79: instantiated from here /usr/include/boost/property_map.hpp:351: error: no match for ‘operator+’ in ‘((const boost::iterator_property_map<__gnu_cxx::__normal_iterator<std::set<long unsigned int, std::less<long unsigned int>, std::allocator<long unsigned int> >*, ... /home/helano/Desktop/temp/extrpg.cpp:79: instantiated from here /usr/include/boost/graph/detail/adjacency_list.hpp:2644: error: no matching function for call to ‘get_property_value(const boost::no_property&, boost::edge_index_t)’ I thought my embedding was well defined, as I followed an example for constructing such structure. Any idea? Thank you in advance! Best regards, Vicente.
