Here is the full example I came up with. I am using visual studio (tried 2010, 2012, and 2013). For completeness I am attaching a file with the polygon definition (test.txt).

#include "stdafx.h"
#include <string>
#include <fstream>
#include <streambuf>
#include <boost/geometry.hpp>
#include "boost/geometry/geometry.hpp"
#include <boost/geometry/extensions/gis/latlong/point_ll.hpp>
#include <boost/geometry/io/io.hpp>

namespace bg = boost::geometry;
using namespace std;

typedef bg::model::ll::point<> point;
typedef bg::model::polygon<point> polygon;

int _tmain(int argc, _TCHAR* argv[])
{
    polygon poly;
    std::string str;

    std::ifstream t("c:\\temp\\test.txt");

    t.seekg(0, std::ios::end);
    str.reserve(t.tellg());
    t.seekg(0, std::ios::beg);

    str.assign((std::istreambuf_iterator<char>(t)),
        std::istreambuf_iterator<char>());

    bg::read_wkt(str, poly);

    const bg::latitude<double> lat_out(37.69311);
    const bg::longitude<double> lon_out(-122.13865);
    point p_out(lat_out, lon_out);

    bg::distance(poly, p_out); // This fails to compile for some reason.

    return 0;
}

Hi,

I am trying to figure out what is wrong with my code and am stuck, so I thought someone might help. The code used to work in 1.55 and in 1.56 no longer compiles; I am at a loss what might be wrong. I am using the GIS extension from the develop-1.56 branch.

Here is the relevant snippet:

    typedef bg::model::ll::point<> point;
    typedef bg::model::polygon<point> polygon;

    polygon poly;

    bg::read_wkt(str, poly);

    const bg::latitude<double> lat_out(37.69311);
    const bg::longitude<double> lon_out(-122.13865);
    point p_out(lat_out, lon_out);

    bg::distance(p_out, poly); // It fails to compile right here.

Does anyone have any suggestions?

Would it be possible to provide a minimal complete example that fails?

Thanks a lot.

Thank you,

Branimir
