Hi,

Hi again,

sorry for the confusion. I tried your example at work (with Boost 1.48) and now at home (using 1.54) and both produce the same errors.

I tested it using VS. To compile under GCC the overloaded bg::intersects() must be defined before the rtree is included. Otherwise the compiler tries to use the original version. Let me know if this works:

#include <boost/geometry.hpp>

struct MyFrustum
{
    MyFrustum(int d) : dummy(d) {}
    int dummy;
};

namespace boost { namespace geometry {

// This will be called for Nodes and Values!

template <typename Box> inline
bool intersects(Box const& b, MyFrustum const& f)
{
    std::cout << "checking the intersection with " << f.dummy << std::endl;
    return true;
}

}}

#include <boost/geometry/index/rtree.hpp>

int main()
{
    namespace bg = boost::geometry;
    namespace bgi = bg::index;
    namespace bgm = bg::model;
    typedef bgm::point<float, 2, bg::cs::cartesian> pt;
    typedef bgm::box<pt> box;

    // check your implementation
    bool ok = bg::intersects(box(pt(0, 0), pt(1, 1)), MyFrustum(5));

    std::cout << "-------------------" << std::endl;

    // now use the rtree
    bgi::rtree<box, bgi::rstar<8> > rt;
    // insert some values
    rt.insert(box(pt(0, 0), pt(1, 1)));
    rt.insert(box(pt(2, 2), pt(3, 3)));

    // performa a query
    std::vector<box> vec;
    rt.query(bgi::intersects(MyFrustum(10)), std::back_inserter(vec));

    std::cout << vec.size() << std::endl;
}

Regards,
Adam
