Help with clear_color.rs example

[crumplecup]

Hi all,

I am new to Rust and Bevy. The error has me flummoxed, any help is appreciated.

The example headless.rs runs for me, but anything that opens a window gets the following error:

What GPU do you use? Do you have a vulkan driver installed for your GPU?

[crumplecup]

As recently as late June, I was able to run some simple 3D examples on this particular machine, but when I came back to it, something has changed. Very likely a self-inflicted wound of some kind.

I was getting a very similar error. Can you post a snippet of your 'use' statements?

[crumplecup]

On my end, it looks like:

git clone https://github.com/bevyengine/bevy
cd bevy
cargo run --example clear_color

clear_color.rs

use bevy::{prelude::*, render::pass::ClearColor};

fn main() {
    App::new()
        .insert_resource(ClearColor(Color::rgb(0.5, 0.5, 0.9)))
        .add_plugins(DefaultPlugins)
        .run();
}

[The-DevBlog]

Weird. I was having the same issue related to 'bevy_wgpu' when I was using the 'bevy::prelude::window' (i think thats it). I ended up removing it for now to temporarily solve the issue. I would assume its related to the ClearColor. Have you removed that just to see if it will compile?

[crumplecup]

If I change DefaultPlugins to MinimalPlugins, then it will compile without error and without further effect.

[The-DevBlog]

Strange. I honestly don't know. I'll look around some more and hopefully find an answer. This same thing was driving me nuts a few days ago.

[crumplecup]

This was an upstream issue and Bevy was not at fault. I ended up switching distros to Arch and I am able to run all examples without issue.
