Hi,
I'm trying to output an image showing subgraphs [0] using write_graphviz() in boost 1.48.0. I've tried to modify an example [1] by adding a write_graphviz() call. eg...
std::ofstream ofs("out.dot"); const char* names[] = { "A", "B", "C", "D", "E", "F" }; write_graphviz(ofs, G0.m_graph, make_label_writer(names));
This works fine for displaying the underlying graph, but no subgraphs are shown. When I do the following...
write_graphviz(ofs, G0, make_label_writer(names));
I get a host of errors including...
include/boost/graph/graphviz.hpp:377: error: no matching function for call to ‘get(boost::label_writer
&, Vertex&)’
Can you please try using write_graphviz_dp instead of write_graphviz? That might work better, and allows you to specify properties to write more easily.
I notice a comment in graphviz.hpp [2] 'requires graph_name graph property' so I had a look at the subgraph_properties.cpp example [3]. This seemed to only be showing vertex properties but didn't compile out of the box. Is it possible for someone experienced in boost::graph to post a modified version of [1] that can produce something like image [0], or point me in the right direction?
I just committed a fixed version of subgraph_properties.cpp to the trunk, so that one should compile now. -- Jeremiah Willcock
