[BUG] mlx_terminate segfaults about mlx42 HOT 5 CLOSED

Well that's a whole new error i've never seen before.
I however simply get:

- docker build -t mlx42-test .
- docker run -it mlx42-test
Failed to initialize GLFW

Which makes sense as there is no display to launch with docker, even with MLX_HEADLESS it won't work as a "Window" context is needed.

Yes, there was a lot of work to overcome 'Failed to initialize GLFW' for me too :D I used xquartz and

echo 'first start docker desktop yourself, else this will not work'
export DISPLAY=127.0.0.1:0
xhost + 127.0.0.1
export BUILDKIT_PROGRESS=plain
docker build --build-arg CACHEBUST=$(date +%s) -t mlx42-app .
docker run --rm -it -e DISPLAY=host.docker.internal:0 \
     -e LIBGL_ALWAYS_SOFTWARE=1 \
     -e LIBGL_ALWAYS_INDIRECT=1 \
     -v /tmp/.X11-unix:/tmp/.X11-unix mlx42-app

• not everything is relevant, but maybe this works

Ok so this took a bit of digging but I found a docker file that handles exactly all of this stuff.

I suggest forking: https://github.com/BoundfoxStudios/docker-opengl

FROM boundfoxstudios/opengl:latest

# Install necessary dependencies
RUN apk update && apk add --no-cache gcc g++ make openssl-dev cmake git bash glfw-dev mesa-dev git

# Clone the repo
RUN git clone https://github.com/codam-coding-college/MLX42.git /MLX42

# Copy your minilibx.c file
COPY minilibx.c /tmp

# Set the working directory
WORKDIR /tmp

# Build the project
RUN cd /MLX42 && \
    cmake -B build && \
    cmake --build build -j4

# Set the default command to compile and run your program
CMD gcc /tmp/minilibx.c -g /MLX42/build/libmlx42.a -I/MLX42/include -ldl -lglfw -pthread -lm && ./a.out

I modified the .c file to just print the address:

# include "MLX42/MLX42.h"
# include <stdio.h>
# include <stdlib.h>

# define WIDTH 512
# define HEIGHT 512

int    main(void)
{
    mlx_t    *mlx;

    mlx_set_setting(MLX_HEADLESS, true);
    if (!(mlx = mlx_init(WIDTH, HEIGHT, "MLX42", true)))
    {
        puts(mlx_strerror(mlx_errno));
        return(EXIT_FAILURE);
    }
    printf("mlx_init: %p\n", mlx);
}

And instead of an error now you get:

Starting Xvfb
Waiting for Xvfb (PID: 7) to be ready...
Xvfb is running.
mlx_init: 0xffff915dd1b0
Waiting for Xvfb (PID: 7) to shut down...

from mlx42.

I tested it with the program in the README.md, seems to work perfectly fine!

If this works for you too i'll add it to the readme or create a Docker example so in the future others can look into how to make it work with Docker and avoid doing all this annoying Xvfb non-sense.

I assume for now, yes, if not, please re-open.
