Thank you for all your replies. I have now updated to boost_1_41 and as you said it only uses Topology. Only problem I have now is at compile time I get an error within the Fruchterman_Reigold algorithm itself given below.
..\boost_1_41_0\boost\graph\fruchterman_reingold.hpp|95|error: 'dimensions' is not a member of 'point'|
It is pointing to the BOOST_STATIC_ASSERT within the Fruchterman_Reingold algorithm as shown below.
template
struct grid_force_pairs { typedef typename property_traits<PositionMap>::value_type Point; BOOST_STATIC_ASSERT (Point::dimensions == 2); typedef typename Topology::point_difference_type point_difference_type; ... any ideas why I am getting this error? Is this a bug within the library itself?
Thanks.
Which topology are you using? This seems like a compiler bug -- rectangle_topology::point is just convex_topology<2>::point which has a dimensions member. You can try changing the BOOST_STATIC_CONSTANT that defines it to an explicit enum or static const member variable; one of those might fix the problem. Otherwise, the quick fix is to just remove the static assert. -- Jeremiah Willcock
