Re: [Boost-users] Why can't I use boost graph write_graphviz with OutEdgeList=listS and VertexList=listS

Hi

Why can't I compile the following simple app. If I changes listS to vecS every thing works just fine. (I'am using boost 1.46.1 and gcc 4.4.5)

#include <iostream> #include #include

int main(int argc, const char *argv[]) { boost::adjacency_list< boost::listS, boost::listS, boost::bidirectionalS > g;

boost::write_graphviz(std::cout, g);

return 0; }

The write_graphviz function requires a vertex_index map, which is not provided by default by graphs with listS as the vertex container. You can add that property explicitly to a listS graph, and fill it in before the write_graphviz call (after any changes to the graph vertices). -- Jeremiah Willcock
