What kind of simple "Hello World" type GUIs work ?

[constantitus]

It is stated in the wiki that only simple "Hello World" type GUIs will work.. So I tried building a simple one with glfw.
Here's the boilerplate code

test.c

#include <stdio.h>
#include <stdlib.h>
#include <GLFW/glfw3.h>

static void error_callback(int error, const char *description) {
    fputs(description, stderr);
}

int main(void) {
    GLFWwindow *window;

    glfwSetErrorCallback(error_callback);

    if (!glfwInit())
        exit(EXIT_FAILURE);

    window = glfwCreateWindow(640, 480, "glfw boilerplate", NULL, NULL);
    if (!window) {
        glfwTerminate();
        exit(EXIT_FAILURE);
    }

    glfwMakeContextCurrent(window);

    while (!glfwWindowShouldClose(window)) {
        glfwSwapBuffers(window);
        glfwPollEvents();
        //glfwWaitEvents();
    }

    glfwDestroyWindow(window);

    glfwTerminate();
    exit(EXIT_SUCCESS);
}

It just tries to open a window, not even asking for an opengl context or anything.
Here's the build command aswell

build command

clang \
    -o test test.c \
    -mmacosx-version-min=10.13 \
    --sysroot=/Library/Developer/CommandLineTools/SDKs/MacOSX10.13.sdk \
    -arch x86_64 \
    -framework Cocoa \
    -framework Opengl \
    -framework IOKit \
    -framework CoreVideo \
    -I./glfw/include \
    -L./glfw/lib-x86_64 \
    -lglfw3

It compiles, but running it gives me the following error

I was just curious, is this supposed to work in darling ?
Unfortunately, I don't have a macos running system atm, so I can't test whether or not what I did is right or the compiled binary works at all on a mac, but I'm glad I was able to get it to at least compile.

We haven't really tested against 3rd party GUI frameworks. The best way to run a simple GUI on Darling is to directly use AppKit (just make sure you are not building a Storyboard app, those are not supported for now)
