I resolved the problem. I should have declared the graphs as: typedef boost::adjacency_list<vecS, vecS, undirectedS, property<vertex_name_t, std::string>, property<edge_weight_t, double, property<edge_lambdas_t, int> >, no_property > Graph; Sorry for the confusion. Best, Irek Irek Szczesniak wrote:
I want to use the read_graphiz function to load graphviz files. Graph links have an extra property called "lambdas," which tells about the number of wavelengths a link has. This link attribute is a positive integer.
Below I'm sending you the program which I thought should work, but it doesn't. Plus, there is a sample graphviz file. I have hard time trying to decipher the errors, and made little progress, and so I would appreciate any advice. I'm attaching the compilation errors.
Thanks for reading.
Thanks & best, Irek
