making a window in opengl and GLFW, a c++ guide

intro
i have made a post on making a window in just opengl but i found most tutorials used GLFW for window displaying

step 1
first install opengl on your Operating System(OS) i am using ubuntu and i installed it from here

step 2
you need to install GLFW for ubuntu linux i found a tutorial here, however you will need to install it for your OS.

step 3

i found the code to making a window off the installation guide to install GLFW for ubuntu here, this is the code:

#include <GLFW/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(640, 480, "Hello World", NULL, NULL); if (!window) { glfwTerminate(); return -1; } /* Make the window's context current */ glfwMakeContextCurrent(window); /* Loop until the user closes the window */ while (!glfwWindowShouldClose(window)) { /* Render here */ glClear(GL_COLOR_BUFFER_BIT); /* Swap front and back buffers */ glfwSwapBuffers(window); /* Poll for and process events */ glfwPollEvents(); } glfwTerminate(); return 0; }
Enter fullscreen mode Exit fullscreen mode

step 4
to compile your main.cpp file you can do

g++ -pthread -o main main.cpp -lglfw -lGLU -lGL -lXrandr -lX11 -lrt -ldl -lglut
Enter fullscreen mode Exit fullscreen mode

i included some extra library's for when you are doing other things with opengl so you wont run into library errors

step 5
enjoy and good luck coding
