Hi everybody, I'm new to BGL and very frustrated beacause I can't make a proper use of dynamic_properties.

I'm just trying to read a graphviz dot file with read_graphviz and I found a sample which make use of dynamic_properties

in order to make a proper call to read_grahviz.

Here is the slightly modified sample:

typedef boost::adjacency_list < boost::listS, boost::vecS, boost::undirectedS > Graph;

typedef boost::graph_traits<Graph>::vertex_descriptor Vertex;

typedef boost::graph_traits<Graph>::vertex_iterator Iterator;

int main(int argc, char **argv)

{

Graph g;

std::ifstream input(argv[1]);

boost::dynamic_properties dp;

dp.property("node_id", boost::get(boost::vertex_name, g));

dp.property("weight", boost::get(boost::edge_weight, g));

boost::read_graphviz(input, g, dp, "id");

return 0;

}

When I try to compile it, g++ returns lots of cryptic template related error messages

but I suspect the most relevant part is : no match for 'operator<<' in 'out << boost::get...'

I must be doing something wrong, but I can't get it; expect you'll point me out my mistake

so that I could re-focus on the algorithms instead of these annoying technical details.
