Opengl test code with GLFW & GLEW compile errors

Hey there! I'm learning OpenGL 3.2+ with GLFW and GLEW.

I'm learning it through this series of tutorials http://open.gl/context but when I run the first code:

        if ( glfwGetKey( GLFW_KEY_ESC ) == GLFW_PRESS )
        break;
        }


    glfwTerminate();


    return 0;
}
Edit & run on cpp.sh


(Then i have the glew.h that is about 17000 lines of code)

I get this errors:

What I'm doing wrong?

I have been for 7 days trying to make it work but it seems impossible, I wish to start building my own engine but I can't due to problems like this.

Thank you,

The first error seems to be pretty clear:

c:\archivos de programa\codeblocks\mingw\bin\..\lib\gcc\mingw32\4.7.1\..\..\..\..\include\GL\glew.h|84|error: #error gl.h included before glew.h|


The error is telling you that glew.h must be included before gl.h. Since you are not including gl.h in your code, it's safe to assume that glfw.h is including it.

So change your includes so that glew.h is included before glfw.h

Now i only get "PRINTF was not declared in this scope"

I just changed the include order, anything more.

How I declare printf?
Jul 7, 2013 at 7:07pm
Disch (13742)
printf is defined in the <cstdio> header.

#include <cstdio>
Jul 7, 2013 at 8:12pm
Marc Colome (40)
Okay, I placed #include <cstdio> on the top of the includes:

#include <cstdio>
#include <iostream>
#include <cstdlib>
#include <GL/glew.h>
#include <GL/glfw.h>
#define GLEW_STATIC



And now I get:

It seems I'm not made for coding in OpenGL

Marc Colome (40)
Oh, and I should build glew?
Jul 7, 2013 at 8:26pm
Niven (114)
I don't think that you should have to build glew. Make sure that you linked all the necessary libraries in your project.
Jul 7, 2013 at 10:07pm

Runs a blank window finally, now I'm looking how to make work the GLM and the GLEW on it

This code works well with GLFW and GLEW

#include <cstdio>
#include <cstdlib>
#include <iostream>
#define GLEW_STATIC
#include <GL/glew.h>
#include <GL/glfw3.h>


int main(void)
{
    GLFWwindow* window;

    // Initialize the library
    if (!glfwInit())
        return -1;

    // Create a windowed mode window and its OpenGL context
    window = glfwCreateWindow(320, 240, "Treball Recerca", NULL, NULL);
    if (!window)
    {
        glfwTerminate();
        return -1;
    }

    // Make the window's context current
    glfwMakeContextCurrent(window);

    //Start of GLEW thing
    glewExperimental = GL_TRUE;
    glewInit();


    GLuint vertexBuffer;
    glGenBuffers( 1, &vertexBuffer );

    printf( "%u\n", vertexBuffer );
    //End of GLEW thing

    // Loop until the user closes the window
    while (!glfwWindowShouldClose(window))
    {
        // Render here


        // Swap front and back buffers
        glfwSwapBuffers(window);

        // Poll for and process events
        glfwPollEvents();
    }

    glfwTerminate();
    return 0;
}

Now I have a question, will I have problems with this tutorials?

http://open.gl/context

The first one (the one that is on the link) makes GLFW and GLEW work in a different way.

I just want to know if I can start coding or if I still have something wrong in my pc and I should fic it


Thank you

Hey marc i was wondering hows your coding going so far?
I started working in c++ myself.
Just curious how far have u reached in your game?
Best of luck, and i hope i get to see it soon.
