I have code using bundled properties roughly like this that compiles with boost 1.42: struct EdgeProperty; typedef adjacency_list< ... , EdgeProperty , ...> MyGraph; typedef graph_traits<MyGraph>::edge_descriptor Edge;
struct EdgeProperty { Edge next; };
When trying to compile this with boost 1.46.1 I get "error: forward declaration of EdgeProperty’". I am not sure why. The obvious solution would be to move the definition of EdgeProperty before the MyGraph typedef, but then I run into a circular dependency problem as I want to store an edge_descriptor in EdgeProperty.
Look at my answer to URL:http://stackoverflow.com/questions/4232409/how-to-solve-boostbgl-templat...; it shows how to use bundled properties that contain vertices and edges from the graph being created. -- Jeremiah Willcock
