Seg Fault When Creating Sprite

[Ktoks]

Bevy version = 0.5

Commit Hash = 9d45353

Operating system & version

Windows 10 build 21390.co_release.210521-1658 , and Ubuntu 20.04 (on WSL2)

What you did

The following code:

use bevy::prelude::*;

const PLAYER_SPRITE: &str = "player_a_01.png";

// entity, component, system, resource

fn main() {
    App::build()
        .insert_resource(ClearColor(Color::rgb(0.04, 0.04, 0.04)))
        .insert_resource(WindowDescriptor {
            title: "Rust Invaders!".to_string(),
            width: 598.0,
            height: 676.0,
            ..Default::default()
        })
        .add_plugins(DefaultPlugins)
        .add_startup_system(setup.system())
        .run();
}

fn setup(
    mut commands: Commands,
    asset_server: Res<AssetServer>,
    mut materials: ResMut<Assets<ColorMaterial>>,
    mut windows: ResMut<Windows>,
) {
    // camera
    commands.spawn_bundle(OrthographicCameraBundle::new_2d());

    // position window
    let window = windows.get_primary_mut().unwrap();
    window.set_position(IVec2::new(1920, 1080));

    // spawn sprite
    commands.spawn_bundle(SpriteBundle {
        material: materials.add(asset_server.load(PLAYER_SPRITE).into()),
        ..Default::default()
    });
}

What you expected to happen

Create a sprite- display it on the screen in a window.

What actually happened

Segmentation fault immediately

Additional information

Bevy examples now work on windows Machine.

If you want to see what I was attempting to build- I was following the tutorial at the following link:

I don't think anything in that code should segfault... Do you have more details?

Could you retry without the position window block which is the only somewhat unusual code that I see?

    // position window
    let window = windows.get_primary_mut().unwrap();
    window.set_position(IVec2::new(1920, 1080));

[Ktoks]

Sure can, I'll give it a shot. Sorry for the delayed response I've been sick.

So after implementing the change you suggested, it works on my windows machine, but still segfaults on WSL Ubuntu. As for 'more details', what else do you need from me?
I'm running this on two installs of rust- one on Windows- which seems to be working as intended now, and one on WSL Ubuntu 20- which is still segmentation faulting.
I am not overly concerned that it doesn't work on WSL for me, it's for those who might have this issue in the future now. I would eventually like to be able to test in both environments though.
New code that works in Windows but segfaults in Linux:

use bevy::prelude::*;
const PLAYER_SPRITE: &str = "player_b_01.png";
// entity, component, system, resource
fn main() {
    App::build()
        .insert_resource(ClearColor(Color::rgb(0.04, 0.04, 0.04)))
        .insert_resource(WindowDescriptor {
            title: "Rust Invaders!".to_string(),
            width: 598.0,
            height: 676.0,
            ..Default::default()
        })
        .add_plugins(DefaultPlugins)
        .add_startup_system(setup.system())
        .run();

}
fn setup(mut commands: Commands,
mut materials: ResMut<Assets<ColorMaterial>>,
asset_server: Res<AssetServer>,
) {
    // camera
    commands.spawn_bundle(OrthographicCameraBundle::new_2d());
    // spawn sprite
    commands.spawn_bundle(SpriteBundle {
        material: materials.add(asset_server.load(PLAYER_SPRITE).into()),
        ..Default::default()
    });
}

After further testing- it causes a segfault in the line:

.add_plugins(DefaultPlugins)

[Ktoks]

I don't know if this is a useful error, I commented out the .add_plugins... line from above:
thread 'main' panicked at 'Requested resource does not exist: bevy_asset::asset_server::AssetServer', /home/kacy/.cargo/registry/src/github.com-1ecc6299db9ec823/bevy_ecs-0.5.0/src/system/system_param.rs:244:17
note: run with RUST_BACKTRACE=1 environment variable to display a backtrace

[shinaka]

This is actually because alsa can't find a sound device at the default '0' in WSL2. I'm not entirely sure how to fix this though, as wslg has pulseaudio setup and other apps have no issue playing audio.

[ghost]

This issue should probably be renamed to: Pulseaudio on WSL2 causes crash on startup due not being able to find audio device
