Thanks Andrew and Volodya, I finally fixed the problem of the compilation with Volodya advice and my scripts work fine with bgl-python-0.9, so don't think I'll go into the other proble by now :) Thanks again! On Thursday 13 November 2008 15:22:25 Andrew Sutton wrote:
Everything was fine here at this step but when running my scripts they
give me
an error in the generation of the Graph object:

This script was working before, any idea of why the edge_property_map attribute cannot be set up in this version of bgl??
I don't know -- boost.graph experts have to say.
It looks like your graph doesn't have an edge property map :) I've never actually used the Python bindings, so this might not translate too well. You have to create your graphs with all of the properties that they're going to use later. My guess is that you're not explicitly creating an edge weight property with the graph, which would lead to this exception.
As a caveat... I don't know if the Python bindings are actively maintained - I'd guess no. It may be tough to get good answers to your questions.
