Running Boost.Graph example 4 for QT gives flowing error:
no match for call to '(boost::dynamic_properties)(std::bacic_ostream>&,unsigned int)' graphvic.hpp
The error occurs at the following line of the graphvic.hpp:
for(boost::tie(i,end) = vertices(g); i != end; ++i) {
out << escape_dot_string(get(vertex_id, *i));
vpw(out, *i); //print vertex attributes
out << ";" << std::endl;
}
I am unable to find out the reason for the error. Below is the Boost.Graph example 4 code. Please help me.

//Writing graph to file
{
std::ofstream f("test.dot");
boost::dynamic_properties p;
p.property("label", boost::get(boost::edge_weight, g));
p.property("weight", boost::get(boost::edge_weight, g));
p.property("node_id", boost::get(boost::vertex_name, g));
boost::write_graphviz(f,g,p);
f.close();
}
Thanks, Prakash
You can change write_graphviz to write_graphviz_dp and try again, it should work, however, i have no idea about the story underneath. could someone give some explanations?
there is invalid call for a function get()
. The second parameter should be a graph, not a vertex descriptor. Additionaly, you did not specify what is it vertex_id
. May be you've meant vertext_name_t
?
