Hello boost,
I'm trying to move some large code base to use boost 1.54.
In some dark corner of it, the following was compiling fine:
class Instance;
typedef boost::setS OutEdgeList;
typedef boost::listS VertexList;
struct InstancePropertyTag {
typedef boost::vertex_property_tag kind;
};
typedef boost::property InstanceProperty;
typedef boost::adjacency_list Graph;
typedef boost::property_map::type IndexGraph;
under 1.54, I get 'attempt to form reference to void', but everything was
fine under 1.46.
I traced it a bit through template expansion, and the problem seems to be
that the type for vertex_index_t is not found.
The following declaration for InstanceProperty fixes (or hides) the problem:
typedef boost::property > InstanceProperty;
Does somebody know if some properties were added by default to graphs
before and need to be explicitly added now?
I don't find anything in the documentation and all examples I've found seem
to imply that one wouldn't need to explicitly
add a property declaration of vertex_index_t.
Thanks a lot,
Maurizio
