Hi Adam, Thanks for the prompt reply. It would be nice if a future version didn't emit those warnings. A colleague of mine who isn't on the mailing list asked me about the warnings, so gave me a snippet of code from which I came up with a minimal compilable test case, but I removed the calls to correct() to get it to compile :) Regards, Pete On 12 May 2015 at 16:54, Adam Wulkiewicz wrote:

Hello,

Using Boost 1.58 on VC9 (MSVC++ 2008) compiling a small program generates warnings in the Geometry headers in Release and Debug modes. Please let me know if this is a Boost.Geometry issue or something I'm not doing correctly.

It's a known Boost.Geometry issue. Internally the coordinates at some point can be rescaled to int64 in some cases and then to the floating point type which trigers the warning. Thanks for reminding about the issue!

The program source =================

#include #include #include #include

typedef boost::geometry::model::d2::point_xy<double> point; typedef boost::geometry::model::polygon polygon; typedef boost::geometry::model::linestring<point> polyline;

int main() { polygon green, blue; green.outer().push_back(point(-1.0, 1.0)); green.outer().push_back(point(1.0, 1.0)); green.outer().push_back(point(1.0, -1.0)); green.outer().push_back(point(-1.0, -1.0));

blue.outer().push_back(point(0.5, 0.5)); blue.outer().push_back(point(0.5, 1.5)); blue.outer().push_back(point(1.5, 1.5)); blue.outer().push_back(point(1.5, 0.5));

std::vector<polygon> output; boost::geometry::intersection(blue, green, output); }

I see one problem though. Your polygon is defined as Counter-Clockwise and Closed see http://www.boost.org/doc/libs/1_58_0/libs/geometry/doc/html/geometry/referen... But the data you pushed back into the polygon define a Clockwise polygon. Plus Closed polygon should have the first and the last point equal. So you should either pass the correct template parameters into the model::polygon, create the polygons differently or call bg::correct() afterwards.

Regards, Adam
