Description

follow code is compile error:

#include <boost/graph/directed_graph.hpp>
#include <boost/graph/undirected_graph.hpp>

using namespace boost;

int main()
{
    directed_graph<> dg(5);
    graph_traits<directed_graph<> >::vertex_descriptor
        dv = vertex(3, dg); // error!

    undirected_graph<> ug(5);
    graph_traits<undirected_graph<> >::vertex_descriptor
        uv = vertex(3, ug); // error!

    return 0;
}
