#621 new defect

Lemon and Boost: call of overloaded ‘ignore_unused_variable_warning(...)’ is ambiguous

Description

Hello dear team of LEMON.

The error is as far as i can tell not new. I have seen back in 2013 there has been an attempt to address that issue here at LEMON in issue #294. As well as on the side of boost in the issue 9438 https://svn.boost.org/trac10/ticket/9438#no1 and 514 https://github.com/boostorg/geometry/pull/514

But it happens still: Because there are ambigous declarations for ignore_unused_variable_warning(...) in boost and lemon the RTree implementations of boost cannot be used with lemon nodes.

Since on the side of boost/geometry the issue has not been tackled further, I would like to ask you if there is a chance of replacement or unambiguously calling ignore_unused_variable_warning() in LEMON.

  • OS: Ubuntu 18.04 Bionic Beaver
  • clang: 6.0
  • lemon: 1.3.1
  • boost: happened under 1.63 and was reproduced with boost 1.68
#include <boost/geometry.hpp>
#include <lemon/list_graph.h>

namespace bg = boost::geometry;
namespace bgi = boost::geometry::index;

using Point = boost::geometry::model::point<double, 2, bg::cs::cartesian>;
using Graph = lemon::ListDigraph;
using Node = lemon::ListDigraph::Node;
typedef std::pair<Point, Node> Pair;
using BoostRTree = bgi::rtree<Pair, bgi::quadratic<16>>;
using BoostQueryResult = std::vector<Pair>;

int main()
{
	Point one = Point(10, 51);
	Point two = Point(10, 51);
	BoostRTree rtreePair = BoostRTree();
	Graph graph;
	Node dummy1 = graph.addNode();
	Node dummy2 = graph.addNode();

	rtreePair.insert(std::make_pair(one, dummy1));	
	return 0;
}

Here is the first error instance of the compiler output. All output has ~200k characters... not sure you want to see it, since the error is raised in boost-code.
