Hi,
I'm trying to write an edge_iterator in order to load a CSR graph from a GraphViz by using the add_edges method.
So far, I successfully write a edge_iterator so you can iterate on it and dereference it to get either a pair of vertex_descriptor or a edge label.
However, if it try to use this iterator as arguments for the method add_edges of CSR graph, I got cryptic errors and I don't know how to solve them :-/
Problem solved. My input_iterator must be copy constructible and was not due to the std::ifstream attribute. Now, I use a boost::shared_ptr and it solves the compilation errors. Thanks anyway. P.S.: It could be a good idea to add an example in CSR documentation that uses this new add_edges method instead of the old add_edge method, which is more difficult to use I think. P.P.S.: Do you plan to adapt the Graphviz reader in order to load CSR graphs? -- Johan () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments
