here is the code:
#include <glad/glad.h>
#include <GLFW/glfw3.h>
#include <iostream>
#include "asteroid.h"
int main()
{
glfwInit();
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
GLFWwindow* window = glfwCreateWindow(800, 800, "YoutubeOpenGL", NULL, NULL);
if (window == NULL)
{
std::cout<< "Failed to create GLFW window"<<std::endl;
glfwTerminate();
return -1;
}
glfwMakeContextCurrent(window);
gladLoadGL();
glViewport(0, 0, 800,800); //area where things are rendered
glClearColor(0.07f,0.13f,0.17f,1.0f);
glClear(GL_COLOR_BUFFER_BIT);
glfwSwapBuffers(window);
while(!glfwWindowShouldClose(window))
{
glfwPollEvents();
}
glfwDestroyWindow(window);
glfwTerminate();
return 0;
}
I tried a very basic one: g++ -o GameWindow Main.cpp
and I got this output in the terminal:
