Hello,
I've recently started using the boost graph library to read a graph in dot format generated with pygraphviz and run some analysis on it. I get the basic example
http://www.boost.org/doc/libs/1_55_0/libs/graph/doc/read_graphviz.html#examp...
to compile, but it then segfaults when reading the file because it can't find the property "colors" (stack trace below). Now I understand that I didn't define this property but I also have no idea how to do it. Debugging it, i find the name="colors", key=0 and value="red" for the function call below:
#11 0x000000010001b40c in boost::put (name=@0x100205880, dp=@0x7fff5fbff5f8, key=@0x100204d78, value=@0x100205888) at dynamic_property_map.hpp:292
292 boost::shared_ptr new_map = dp.generate(name, key, value);
For a general understanding of what's happening: What is "key" good for? In the example, where is the variable vertex_color declared? What is this "mass" property and why does it contain vertex_color? What is the type vertex_color_t? The documentation didn't help me, maybe there are easier starting points or i've just looked in the wrong parts of
http://www.boost.org/doc/libs/1_55_0/libs/graph/doc/table_of_contents.html
If someone could point me to a proper example/tutorial/documentation it'd be greatly appreciated.
Best regards,
Robert Langenberg
