'_nextafter' not declared : CGAL in Qt Creator with Windows 8.1

I've build CGAL like explained here.

Everything went well.

But now, I'm using Qt Creator with CGAL.

I've included the libraries in the .pro file :

QT       += core

QT       -= gui

TARGET = TestCCGALAppliConsole
CONFIG   += console
CONFIG   -= app_bundle
CONFIG += c++11

and in my main.cpp I have :

#include <CGAL/Exact_predicates_inexact_constructions_kernel.h>
#include <CGAL/Polyhedron_3.h>
#include <CGAL/Polyhedron_items_with_id_3.h>
#include <CGAL/IO/Polyhedron_iostream.h>

#include <iostream>
#include <fstream>

typedef CGAL::Exact_predicates_inexact_constructions_kernel         K;
typedef CGAL::Polyhedron_3<K, CGAL::Polyhedron_items_with_id_3>     Polyhedron;
typedef Polyhedron::Vertex_iterator                                     Vertex_iterator;

int main() {

    Polyhedron mesh;
    std::ifstream input("inner.off");

    if ( !input || !(input >> mesh) || mesh.empty() )
    {
        //Debug
        std::cerr << "Not a valid off file." << std::endl;
        return 0;
    }

    for (Vertex_iterator v = mesh.vertices_begin() ; v!= mesh.vertices_end() ; ++v )
    {
        std::cout << v->point() << std::endl;
    }

    std::cout << "Hello You" << std::endl;

    return 0;
}

when I compile (with MinGW 4.9.1 32 bit with Qt 5.4.1) I'm having this error :

C:\local\CGAL-4.6\include\CGAL\double.h:191: erreur : '_nextafter' was not declared in this scope return _nextafter(d1, d2); // works at least for VC++-7.1

I can't figure out what's wrong...

Can you help me ?

EDIT

It seems that CGAL being compiled with Visual Studio C++ Compiler 10 involves that I have to compile with this compiler and not MinGW.

So I changed compile, I'm now using Microsoft Visual C++ Compiler 10 (amd64) in Qt Creator, but it still don't work. I have an error :

impossible to open 'CGAL-vc100-mt-4.6.lib' file

Here's the complete error (sorry, french version...) :

How did you build CGAL exactly? Was -std=c++11 involved at any point? That would explain it (you want -std=gnu++11 instead). – Marc Glisse
Wait, the instructions you are linking are for compiling CGAL with Visual Studio, and now you expect to use the result with mingw? That doesn't make sense... – Marc Glisse

Well, it's right there in your message:

when I compile (with MinGW

versus

works at least for VC++-7.1

_nextafter is a Microsoft extension used by CGAL. MinGW doesn't appear to support it.
