I have had some difficulty using the current version of the reverse_graph adapter on the Boost Graph Library. It seems to require the class being reversed to have types that a user class that has been adapted using graph_traits et al may not have. I have attached an example that shows the problem which includes comments to describe what I think the problem is. I have also attached a modified version of reverse_graph.hpp that works with this example. I would appreciate any help. Thanks, -Tony Attached files: bug_report_example_skeleton.hpp An include file the contains a minimal user defined graph MyGraph together with the required interfaces to adapt it to be a Boost Graph. bug_report_example_reverse_graph.cpp An example showing the problems encountered with the current reverse_graph.hpp reverse_graph.hpp An altered version of reverse_graph.hpp that works with the example.
