Comecei a aprender o OpenGL (glfw) e copio o código-fonte de um tutorial e tentei compilá-lo, mas ocorreram erros. Acho que instalei corretamente todos os arquivos de cabeçalho (glm, glfw etc.)

Esta é a minha fonte (não usei esses caracteres: <,> nos arquivos de cabeçalho):

#include iostream
#include stdio.h
#include stdlib.h
#include GL/glew.h
#include GLFW/glfw3.h
#include glm/glm.hpp

#define GLFW_INCLUDE_GL_3

using namespace glm;
using namespace std;

int main(){
    if(!glfwInit()){
        return -1;
     }

     GLFWwindow* window; // (In the accompanying source code, this variable is global)
     window = glfwCreateWindow( 1024, 768, "Tutorial 01", NULL, NULL);
     if( window == NULL ) {
         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;
     }

     glfwMakeContextCurrent(window);

     // Initialize GLEW
     glewExperimental=true; // Needed in core profile
     if (glewInit() != GLEW_OK) {
         fprintf(stderr, "Failed to initialize GLEW\n");
         return -1;
     }

     return 0;
 }

e esta é a saída no NetBeans:

Por favor me ajude. Obrigado pelo seu tempo.
