Re: [Boost-users] [bgl] Problem with topological_sort

Aaron Windsor a écrit :

Did you initialize the vertex index map? If you're using a std::vector to store the vertices, you get a vertex index map for free, but if you use anything else, (a std::list, for example) you must actually go through all of the vertices and set their index, like so:

Thank you for the information. I solved my problem in another way, using the topological_sort overload where I specify the color property map manually, and which does not need vertex indexes, but your code will prove useful when I used other algorithms that use the index. Thank you. Best regards, -- Loïc
