`[LEIF ERROR]: Failed to initialize Glad.`

[Sigmanificient]

I had this error when running the binary

$ lyssa
Lyssa: [ERROR]: Failed to create GLFW window 'Lyssa Music Player'.
[LEIF ERROR]: Failed to initialize Glad.
[1]    1405981 segmentation fault (core dumped) lyssa

I have the glad binary in PATH

[cococry]

on which distro are you on? and are you using wayland or xorg?

I use NixOS 23.11 with Xorg

Try this:

touch glfw.c
nvim glfw.c

#include <GLFW/glfw3.h>

int main(void)
{
    GLFWwindow* window;

    /* Initialize the library */
    if (!glfwInit())
        return -1;

    /* Create a windowed mode window and its OpenGL context */
    window = glfwCreateWindow(640, 480, "Hello World", NULL, NULL);
    if (!window)
    {
        glfwTerminate();
        return -1;
    }

    /* Make the window's context current */
    glfwMakeContextCurrent(window);

    /* Loop until the user closes the window */
    while (!glfwWindowShouldClose(window))
    {
        /* Render here */
        glClear(GL_COLOR_BUFFER_BIT);

        /* Swap front and back buffers */
        glfwSwapBuffers(window);

        /* Poll for and process events */
        glfwPollEvents();
    }

    glfwTerminate();
    return 0;
}

gcc -o glfw glfw.c -lglfw -lGL
./glfw

The binary do not produce any output.

I went ahead and added the following changes to retrieve information on what could fail.

And now a error is showing up:

$ ./glfw 
2: Resource temporarily unavailable

I was wondering if this could be an issue with my integrated graphics chipset, and tried runnint it by using my nvidia card:

$ nvidia-offload ./glfw 

[Sigmanificient]

Trying the same with lyssa, however, was not successful:

Maybe this could be related, i'm not sure: https://stackoverflow.com/questions/68051588/segmentation-fault-with-glviewport-opengl-c-programming-with-glfw-and-glad

[cococry]

i mean you could try removing glViewport from leif.c just search for it and remove every line where it is used. then rebuild leif and lyssa and try if that fixes it.

Unfortunately, it doesn't seems to help
