No sure how to set up Opengl

[MrPak]

I am learning c++ and i would like to try to make a 2d game and I heard that for c++ opengl is the best option .I have Visual Studio 2013 and i am not sure how to set up opengl with it . There aren't many tutorials online and i am just not sure which opengl files i need and how to link them . Thank you

I personally prefer to use SFML as the window manager and have it set up the OpenGL context for me. Aside from doing that, it also offers input, window events, and audio functionality which OpenGL does not provide on its own.

http://www.sfml-dev.org/


The arcsynthesis tutorial shows how to set up without SFML, although I think it uses FreeGLUT in its place:

http://www.arcsynthesis.org/gltut/

Note: The arc synthesis tutorial is worth reading regardless -- it is hands down the best OpenGL tutorial I've ever seen. Don't trust any site that has you using glBegin/glEnd.

Thank you I will try this could you point out which part of the tutorial tells you how to link the sumo,libraries to visual studio ?

I have followed the instructions on the website on how to link everything and tried to run some SFML code to see if it works . In the debugger i got these errors:

What did I do wrong ?

You're not linking to the sfml libs.

For visual studio I just make a common "sfml.h" header file that pragma links all these libs so I don't have to deal with it:

#pragma once
#ifndef SFMLFULL_INCLUDED
#define SFMLFULL_INCLUDED

#define SFML_STATIC
#define GL_GLEXT_PROTOTYPES

#include <SFML/Audio.hpp>
#include <SFML/Graphics.hpp>
#include <SFML/OpenGL.hpp>
#include <SFML/Network.hpp>
#include <SFML/System.hpp>
#include <SFML/Window.hpp>

#if defined(_DEBUG) || defined(DEBUG)
    #pragma comment(lib,"sfml-graphics-s-d.lib")
    #pragma comment(lib,"sfml-audio-s-d.lib")
    #pragma comment(lib,"sfml-network-s-d.lib")
    #pragma comment(lib,"sfml-window-s-d.lib")
    #pragma comment(lib,"sfml-system-s-d.lib")
    #pragma comment(lib,"sfml-main-d.lib")
#else
    #pragma comment(lib,"sfml-graphics-s.lib")
    #pragma comment(lib,"sfml-audio-s.lib")
    #pragma comment(lib,"sfml-network-s.lib")
    #pragma comment(lib,"sfml-window-s.lib")
    #pragma comment(lib,"sfml-system-s.lib")
    #pragma comment(lib,"sfml-main.lib")
#endif


#endif // SFMLFULL_INCLUDED 

#include this header instead of the usual sfml headers and those problems should go away.
