macOS OpenGL hello world using GLFW
What a beautiful cyan! I made this window on macOS using C, OpenGL and GLFW. Here’s the C:
// main.c
#include <GLFW/glfw3.h>
int main(void) {
if (!glfwInit()) return -1;
GLFWwindow* window = glfwCreateWindow(320, 240, "Hello World", NULL, NULL);
if (!window) {
glfwTerminate();
return -1;
}
glfwMakeContextCurrent(window);
glClearColor(0.0f, 1.0f, 1.0f, 1.0f);
while (!glfwWindowShouldClose(window)) {
glClear(GL_COLOR_BUFFER_BIT);
glfwSwapBuffers(window);
glfwPollEvents();
}
glfwTerminate();
return 0;
}
To compile it:
$ brew install glfw3
$ clang -lglfw -framework OpenGL main.c
$ ./a.out
GLFW is an abstraction over the different window systems of MacOS, Linux, Windows, etc. This C should also work on Windows or Linux, though the compilation steps may look different.
