Hello all,
The following parameter type requirement:
(required (graph, *) ) (optional (root_vertex, (typename boost::graph_traits<graph_type>::vertex_descriptor), *boost::vertices(graph).first) )
Generates a GCC error:
dfs.05.cpp:40: error: ‘graph_type’ was not declared in this scope
Yeah.... I'm guessing this is what graphs::graph::_ is all about, but according to revision control, Daniel made this happen, and there's basically no documentation for it. Daniel?
Detailed code and error below.
In fact, if I look at the code after pp, I can see that graph_type is define only after the type requirement is checked... why? What am I doing wrong?
Thanks a lot!
