Re: [Boost-users] Boost Graph: vertex class has no copy constructor

The "easy" workaround is to simply have the graph refer to BasicBlock by pointer instead of actually owning it. Pointers are definitely default and copy constructible :)

Yes, I had tried that, and the pointers are added to the graph okay using add_vertex, but when I try to pull them out using, say, graph[0], my program segfaults. I have no idea what I'm doing wrong.

I might caution you about using directed_graph. It's built over adjacency_list so it might not be usable quite the same way that most of the documentation is listed.

So instead of: typedef directed_graph TimingGraph; I should do maybe: typedef adjacency_list TimingGraph; ? Trevor
