Panic when running basic iced application on armv7-unknown-linux-gnueabihf

[rbwork2024]

Is your issue REALLY a bug?

• My issue is indeed a bug!
• I am not crazy! I will not fill out this form just to ask a question or request a feature. Pinky promise.

Is there an existing issue for this?

• I have searched the existing issues.

Is this issue related to iced?

• My hardware is compatible and my graphics drivers are up-to-date.

What happened?

Feel free to close this if the architecture is not supported, but I was intending to run a simple iced application on an embedded display, and when running it got this issue:

EGL: Warning: No default display support on wayland
thread 'main' panicked at /cargo/registry/src/index.crates.io-6f17d22bba15001f/khronos-egl-6.0.0/src/lib.rs:1779:38:
called `Option::unwrap()` on a `None` value
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Minimal reproduction:

use iced::{widget::text, Element, Task};

#[derive(Default, Clone, Debug)]
struct State {}

#[derive(Debug, Clone)]
struct Message {}

fn main() -> iced::Result {
    iced::run("Application", State::update, State::view)?;
    Ok(())
}

impl State {
    fn view(&self) -> Element<Message> {
        text!("Hello").into()
    }

    fn update(&mut self, m: Message) -> Task<Message> {
        Task::none()
    }
}

Compile with (with docker or podman installed):

cargo install cross
~/.cargo/bin/cross build --release --target armv7-unknown-linux-gnueabihf

What is the expected behavior?

A simple application with no widgets should be able to start up, rendering a window.

Version

crates.io release

Operating System

Linux

Do you have any log output?

RUST_LOG=trace ./application
