Wont compile without -lX11

[ghost]

I am attempting to make a function that get the resolution and refresh rate of the monitor(only figured out resolution so far) and I can only compile it atm by running the function in its on project and building it with cargo rustc -- -lX11

My Code

use std::ptr;
use x11::xlib::{XCloseDisplay, XOpenDisplay, XScreenCount, XScreenOfDisplay};

pub fn resolution() {
    unsafe {
        // open a display
        let display = XOpenDisplay(ptr::null());
        // return the number of available screens
        let count_screens = XScreenCount(display);

        println!("Number of screens: {}", count_screens);
        for i in 0..count_screens {
            let screen = *XScreenOfDisplay(display, i);
            println!("\tScreen {}: {}x{}", i + 1, screen.width, screen.height);
        }
        // close the display
        XCloseDisplay(display);
    }
}

pub fn main() {
    resolution();
}

This my Cargo.toml

[package]
edition = "2018"
 
[dependencies]
libc = "0.2"
x11 = "2.18.1"

Am I doing something wrong? Is there anyway I can run this from with a project with multiple file inside the src directory?

It adds -lX11 when the xlib feature is enabled. It was left off by default for those who want to use the other libraries but not libX11.

[dependencies]
x11 = { version = "2.18.1", features = ["xlib"] }

Oh my mistake, that makes a lot of sense.

Is it possible to get screen resolution and refresh rate using your library without using the xlib for wayland systems?

Thanks I didnt even know there were feature flags

[ids1024]

The bindings for xlib functions probably shouldn't be complied in when that feature isn't used.
