Dear list,
I need to keep track of two special vertices in my graph, So
I thought to attach two vertex_descriptor as graph
properties so have easy access any moment. Properties work
fine for edges or vertices, but I cannot make them work for
the graph.
In the bottom is the C++ code. The graph has the two properties,
now how I cat get and put them? This code does not work and
the error messages are impossible to read for me.
Otherwise that is the way to keep graph-wise properties?
The code compiles removing the two puts, so I assume the
error is there.
Yours sincerely,
Paolo

enum graph_source_t { graph_source = 100 };

BOOST_INSTALL_PROPERTY (graph, destination);
}
typedef size_t graph_vertex;

static_assert(std::is_same::vertex_descriptor>::value, "Check out
the vertex descriptor type!");
int main() {
using namespace boost;
graph_t g;
add_edge(0, 1, g);
put(graph_destination, g, 0);
put(graph_source, g, 1);
}
