Dick Hadsell has offered you advice about fixing up your included
headers, in particular to resolve the "deprecated or antiquated header"
warning. However, you are left with the error:

i.e. you are passing a variable of the wrong type as the first parameter
to add_vertex.

Instead try:

   for ( QStringList::Iterator it = lst.begin(); it !=
      lst.end(); ++it ) {
             boost::graph_traits<MyGraphType>::vertex_descriptor v;
             // name[v]=*it; This throws from QString
             property<vertex_first_name_t, QString> p( *it );
             v = add_vertex(p,G);
             cerr << *it << endl;
             filesnum++;
   }

This compiles and runs, but I don't know whether it does what you want ;-)

I hope this helps.
