BGL write_graphviz won't compile with listS or setS
I cannot get calls to write_graphviz to work when using anything other than vecS for the vertex and edge descriptors. I get the following error: graphviz.hpp:255: error: no matching function for call to ‘get (boost ::bgl_named_params <boost::bundle_property_map<boost::adjacency_list<boost::listS, boost::vecS, boost::directedS, VertInfo, boost::no_property, boost::no_property, boost::listS>, size_t, VertInfo, int>, boost::vertex_index_t, boost::no_property>&, const long unsigned int&)’ I am using bundled properties for the vertex properties, as shown below. Any ideas as to why the setS and listS containers do not work with write_graphvis? James --------------------------------- struct VertInfo { string name; int index; }; template<typename GraphT> struct VertWriter{ typedef typename graph_traits<GraphT>::vertex_descriptor Vertex; VertWriter( GraphT& _g ) : g(_g) {} void operator()( ostream& os, const Vertex& v ) const{ os << "[label=\"" << g[v].name << "\"]"; } private: GraphT& g; }; int main() { // typedef adjacency_list< vecS, vecS, directedS, VertInfo > Graph; // works. typedef adjacency_list< listS, listS, directedS, VertInfo > Graph; // doesn't work. Graph G; // populate the graph with vertex info set on each vertex... VertWriter<Graph> vw(G); boost::default_writer dw; write_graphviz( cout, G, vw, dw, dw ); } ----------------------------------- NOTE: I have also tried write_graphviz( cout, G, vw, dw, dw, vertex_index_map( boost::get(&VertInfo::index,G) ) ); which gives the same compiler error.
Dear All, has anybody tried to integrate boost::spirit with a lexer generated by Flex? I'm having: int yylex (boost::any &yylval); The boost::any may be changed later into boost::variant. Any tips would be helpful. Any experiences how fast such a parser is running? Thanks Peter

You can use the multi_pass iterator in the Spirit library for encapsulating a flex based lexer. Regards Hartmut
Hi, I'm using write_graphviz with listS and internal properties. I think I had a similar problem until I explicitly used the vertex_index_t property. The vertex index is implicit with vecS because it is the vertex desriptor in this case. Cheers, Torsten Am 05.05.2008 um 22:24 schrieb James Sutherland:

Torsten, How would you change the vertex descriptor struct? From my original example, would the following be on the right track? template<class Graph> struct VertInfo { string name; typename Graph::vertex_index_t index; };
I am not sure. My graph is defined thus: // Declarations of properties enum vertex_pnt_t { vertex_pnt = 0 }; namespace boost { BOOST_INSTALL_PROPERTY( vertex, pnt);} enum vertex_isinside_t { vertex_isinside = 1 }; namespace boost { BOOST_INSTALL_PROPERTY( vertex, isinside );} // Declarations for my dual graph typedef boost::property<vertex_pnt_t, gp_Pnt, boost::property<vertex_isinside_t, Standard_Boolean, boost::property<boost::vertex_index_t, int> > > VertexProp; typedef boost::property<boost::edge_index_t, int> EdgeProp; typedef boost::adjacency_list<boost::listS, boost::listS, boost::undirectedS, VertexProp, EdgeProp > TMESH_ConnectivityGraph; Torsten

Thanks. Perhaps I will try this using property lists as you have. I am using bundled properties (a really nice feature), and am unable thus far to get write_graphviz to work with listS and bundled properties. I don't see any examples in BGL of this, so perhaps it is a bug, or unsupported... James
