I am following a tutorial on 3D Environments in C++, and am trying to initialize these glut functions, but I get several errors on compile. Another stack overflow answer explained that you have to change your IOS X Development to 10.8 I believe, but I don’t know how to do that.

How can I resolve these errors?

CODE:

#include <iostream>
#include <GLUT/glut.h>

void display(){
    glutSwapBuffers();
}
int main(int argc, char **argv){
    
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE);
    glutInitWindowSize(800,600);
    glutCreateWindow("");
    glutDisplayFunc(display);
    glutMainLoop();
    return 0;
   
}
