Subject: [Boost-users] Strange problem with boost/graph/subgraph.hpp
From: Paolo Bolzoni (paolo.bolzoni.brown_at_[hidden])

Dear list,
I cannot compile a simple example using the subgraph implementation.
I enclosed the code in the bottom of this email. It is quite short,
but it is the whole code. It does not compile with errors from
inside boost/graph/detail/adjacency_list.hpp about the impossiblity
of making a reference to void.

I read the subgraph documentation but I cannot understand why it
does not work.

Can anyone enlighten me?

Your faithfully,

The code:

------------------ >8

#include <boost/graph/adjacency_list.hpp>
#include <boost/graph/subgraph.hpp>

typedef boost::adjacency_list
> main_graph;

typedef boost::subgraph <main_graph> sub_graph;

typedef boost::graph_traits<sub_graph>::vertex_descriptor Bvertex;
