Hi There, I am struggling with BOOST while trying to link them with my code. Actually I start while using "loops_dfs.cpp" as an example.

From that I isolated the following code which compiles without any problem:

typedef adjacency_list < vecS, vecS, bidirectionalS,GraphvizVertexProperty,GraphvizEdgeProperty, GraphvizGraphProperty > Graph; Graph _graph2; typedef color_traits < default_color_type > Color; typedef graph_traits < Graph >::vertex_descriptor VertexType; typedef graph_traits < Graph >::edge_descriptor EdgeType; EdgeType back_edge;//ok I know it is empty but it just to try the compilation!! VertexType loop_head, loop_tail; loop_tail = source(back_edge, _graph2); loop_head = target(back_edge, _graph2); std::vector < default_color_type > reachable_from_head(num_vertices(_graph2), Color::white()); default_color_type c; depth_first_visit(_graph2, loop_head, default_dfs_visitor(), make_iterator_property_map(reachable_from_head.begin(),get(vertex_index, _graph2), c)); So this works fine! Then, I would like to change the type of graph, so more precisely, to use a std::list (or listS) instead of a std..vector (vecS) for the VertexListS So the first line declaration becomes: typedef adjacency_list < vecS, listS, bidirectionalS,GraphvizVertexProperty,GraphvizEdgeProperty, GraphvizGraphProperty > Graph; //only the 2nd argument changes But then when I compile the code, I get 1 error during the compilation as described hereafter. Since I am fighting for more than one day now on this problem, I would **really** appreciate if someone can give me more explanations and/or advice to solve my problem...
