I'm trying to write a testcase for graphml.hpp/.cpp from graph-tool.
I have the following:
#include
#include
#include
#include <iostream>
#include
#include <map>
#include "./graphml.hpp"
enum edge_length_t { edge_length };
namespace boost {
BOOST_INSTALL_PROPERTY(edge, length);
}
int main(int argc, char* argv[]){
// create a typedef for the Graph type
using namespace boost;
typedef boost::adjacency_list
> Graph;
Graph g;
std::ifstream input(argv[1]);
boost::dynamic_properties properties;
typedef graph_traits<Graph>::vertex_descriptor vertex_descriptor;
std::map coord1;
boost::associative_property_map< std::map >
coord1_map(coord1);
properties.property("coord1", coord1_map);
std::map coord2;
boost::associative_property_map< std::map >
coord2_map(coord2);
properties.property("coord2", coord2_map);
// typedef graph_traits<Graph>::edge_descriptor edge_descriptor;
properties.property("length", get(edge_length, g));
boost::read_graphml(input, g, properties);
}
It runs fine, but when I compile it, I get the following warning:
/usr/lib/gcc/x86_64-pc-linux-gnu/4.1.1/include/g++-v4/ext/new_allocator.h:
In member function 'std::pair
boost::mutate_graph_impl<MutableGraph>::do_add_edge(boost::any,
boost::any) [with MutableGraph = boost::adjacency_list,
boost::no_property, boost::listS>]':
/usr/lib/gcc/x86_64-pc-linux-gnu/4.1.1/include/g++-v4/ext/new_allocator.h:106:
warning: 'p$m_value' is used uninitialized in this function
I suppose this is nothing bad?
Is there a good way to use a "dummy map" which does not store anything?
Any comments on the code are highly appreciated ...
