Macbook Air 2020, m1 chip, macOS 12.1 Monterey. No XCode. Though I have XCode Command Line tools.

I'm trying out OpenGL. I installed it: brew install glfw. I wrote this test.cpp:

#include <GLFW/glfw3.h>
int main(void)
{
    
    GLFWwindow* window;

    if (!glfwInit())
        return -1;

    return 0;

}

In Terminal, I run g++ -I/opt/homebrew/Cellar/glfw/3.3.6/include -o ./test ./test.cpp

And get this error: clang: error: linker command failed with exit code 1 (use -v to see invocation)

What should I do?

Add a -l (minus-EL) option for the library that contains glfwInit. – Joseph Larson Jan 13 '22 at 22:31

You set the include directory but you failed to link to the glfw libraries – drescherjm Jan 13 '22 at 22:31

`g++ -I/opt/homebrew/Cellar/glfw/3.3.6/include -o ./helloworld ./test.cpp -lglfw -framework Cocoa -framework OpenGL -framework IOKit` worked – Evgeniy Volkov Jan 13 '22 at 22:56
