Why do i get the error : C 'cmath' : No such file or directory when i try to compile a project using Visual studio 2012

I am trying to compile the "gop program" , I selected the Visual C compiler located in the following folder:

C:\Program Files\Microsoft Visual Studio 11.0

When I then try to build the model , I get the following Erreur : error C1083: Impossible d'ouvrir le fichier include : 'cmath' : No such file or directory c:\users\hp\desktop\gop_1.3\lib\util\win_util.h thank you for your help

You are trying to compile C++ code with a C compiler.

I followed the CMakeLists file,so i have to use a C compiler to run the program but when i'am trying to run it i have error in the header file 'win_util':

#pragma once

#ifdef _MSC_VER

#define _USE_MATH_DEFINES

#endif

#include <cmath>

And the error is in the last line #incude <cmath>

[Walter Roberson]

That is C++ source. You need a C++ compiler.

Where did you obtain the source code?

[Houayda Gharbi]

from here http://www.philkr.net/ u find the second pubication " Geodesic object proposal " [codes]

[Walter Roberson]

The Readme.md file says:

Required:
 * cmake
 * c++11 compiler( g++-4.7 or higher, vc++2013 or higher, clang might work too )
 * Eigen 3.2 (optionally you can download eigen and put in in external/eigen such that external/eigen/Eigen is a valid directory)
 * libpng and libjpg (needed by cimg)

so Yes it is a C++ compiler that is needed. You will need to install one.

[Houayda Gharbi]

So i need to install g++ 4.7 then compile my program with it. And is it necessary to upgrade MinGW?

[Walter Roberson]

You have Visual Studio 11.0, which appears to have been released in 2012. If you upgraded to Visual Studio 2013 or later then that should work; it is also plausible that SDK 7.1 might work.

I have not kept track of what g++ requires.

Thank you very much for your efforts
