Hi,
vertex_property and edge_property should inherit publicly from
vertex_property_type and edge_property_type. A patch follows.
{{{
./ContigGraph.h:55:39: error: 'type' is a private member of
'boost::mpl::eval_if<boost::detail::has_vertex_property_type<DirectedGraph<ContigProperties,
Distance>, mpl_::bool_<false>>,
boost::detail::get_vertex_property_type<DirectedGraph<ContigProperties,
Distance>>, boost::no_property>'
typedef typename vertex_property<G>::type vertex_property_type;
^
/usr/local/include/boost/graph/properties.hpp:251:49: note: constrained by
implicitly private inheritance here
template <class Graph> class vertex_property:
vertex_property_type<Graph> {};
^~~~~~~~~~~~~~~~~~~~~~~~~~~
}}}
Cheers,
Shaun
