I am currently learning how to use OpenGL for Windows.
To check if i set up the libraries correctly, i am compiling a set of tutorials that should work.
Right now im following this set:
http://www.opengl-tutorial.org/beginners-tutorials/tutorial-2-the-first-triangle/
The previous tutorial compiled fine, so i was sure i had everything set up correctly, but the second one keeps screwing me over, i cant really find any issue with my setup either.
I am using Visual Express c++ 2010.
In source-files i have:
main.cpp:
// Include standard headers
#include <stdio.h>
#include <stdlib.h>
// Include GLEW
#include <GL/glew.h>
// Include GLFW
#include <GL/glfw.h>

return -1;
}

// Open a window and create its OpenGL context
if( !glfwOpenWindow( 1024, 768, 0,0,0,0, 32,0, GLFW_WINDOW ) )
{
fprintf( stderr, "Failed to open GLFW window. If you have an Intel GPU, they are not 3.3 compatible. Try the 2.1 version of the tutorials.\n" );
glfwTerminate();
return -1;

(void*)0 // array buffer offset
);
// Draw the triangle !
glDrawArrays(GL_TRIANGLES, 0, 3); // From index 0 to 3 -> 1 triangle
glDisableVertexAttribArray(0);
// Swap buffers
glfwSwapBuffers();
} // Check if the ESC key was pressed or the window was closed
while( glfwGetKey( GLFW_KEY_ESC ) != GLFW_PRESS &&
glfwGetWindowParam( GLFW_OPENED ) );
// Close OpenGL window and terminate GLFW
glfwTerminate();
// Cleanup VBO

In headers i have:
shader.h:
#ifndef SHADER_H
#define SHADER_H
GLuint LoadShaders(const char * vertex_file_path,const char * fragment_file_path);
#endif
In Resource-files i have:
SimpleFragmentShader.fragmentshader:
#version 330 core
// Ouput data
out vec3 color;
void main()
{
// Output color = red
color = vec3(1,0,0);
}
SimpleVertexShader.vertexshader:
#version 330 core
// Input vertex data, different for all executions of this shader.
layout(location = 0) in vec3 vertexPosition_modelspace;
void main(){
gl_Position.xyz = vertexPosition_modelspace;
}

And from tutorial 1 :
I just modified the tutorial because so many people get stuck at this.
What’s more, if you use the standard version of GLEW instead of the one that is bundled with the tutorial, you won’t be able to use the Core Profile because of a GLEW bug. Use
instead of
