问题
I am running Mac OS X Sierra 10.12.6 (16G29). I am working on a macbook pro.
I have installed brew and the following packages:
brew install glfw3
brew install glew
brew install glm
Here is my c++ program:
#include <iostream>
#include <GLFW/glfw3.h>
GLFWwindow* window;
#include <GL/gl.h>
int main(int argc, const char * argv[])
{
if (!glfwInit())
{
return -1;
}
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
// Should be true for macOS, according to GLFW docs, to get core profile.
glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
// According to Apple docs, non-core profiles are limited to version 2.1.
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
window = glfwCreateWindow(640, 480, "Test 1", NULL, NULL);
if( window == NULL )
{
return -1;
}
glfwMakeContextCurrent(window);
// glGetString(GL_VERSION) is NULL at this point
return 0;
}
And here is the command line i am running to compile my program:
g++ program.cpp -I/opt/X11/include -L/opt/X11/lib -lglfw -lGL -lGLEW
There is a runtime problem because i get a NULL window. I have compiled the same code on a Linux virtual machine and it works great...

This is answered in the GLFW docs: http://www.glfw.org/docs/latest/window_guide.html
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
// Should be true for macOS, according to GLFW docs, to get core profile.
glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
// According to Apple docs, non-core profiles are limited to version 2.1.
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
