Hi!

From your code I can assume that directed_graph does not name a type is not the only error you receive.

You write: typedef adjacency_list directed_graph; If compiler does not know vecS, directedS, vertex_property, edge_property it also can't produce the template instantiation. Ok, vertex_property, edge_property are defined upon, but where are vecS, directedS? If these are in some other includes, ensure that they are visible at the point of instantiation. Sorry, if I am wrong. This is what I can conclude from viewing your code. Best Regards, Ovanes On Tue, January 9, 2007 21:13, Alec Resnick wrote:

It would seem that I'm having a bit of trouble nailing down the scope of a typedef of the adjacency_list type in a class I'm writing. For some reason, I keep getting the error "error: 'directed_graph' does not name a type" when trying to compile the following code using XCode 2.4 with the boost library installed via DarwinPorts and the appropriate library and search paths (/opt/local/lib/ and /opt/local/ include/) set.

If someone could help me out with this, I would very much appreciate it. Thanks for your time!

Gratefully, a.
