issues on getting started

[ghost]

Hi, I am new to Bevy and I was following the tutorial,
but it seems like something's wrong on my side after adding the DefaultPlugins,

for some reason, on my end, the code doesn't loop as it is said it should, it just runs once and then exits with 0,
I don't see where this could be coming from

my code :

use bevy::prelude::*;

struct Person;
struct Name(String);

fn add_people(commands: &mut Commands) {
    commands
        .spawn((Person, Name("Person 1".to_string())))
        .spawn((Person, Name("Person 2".to_string())))
        .spawn((Person, Name("Person 3".to_string())));
}

struct GreetTimer(Timer);

fn greet_people(query: Query<&Name, With<Person>>) {
    for name in query.iter() {
        println!("Hello {}!", name.0);
    }
}

fn main() {
    App::build()
        .add_plugins(DefaultPlugins)
        .add_startup_system(add_people.system())
        .add_system(greet_people.system())
        .run();
}

Can you paste the full output, and the output of cargo version? This works for me

don't mind the warning

[TheRawMeatball]

can you try compiling with stable?

[ghost]

It does the same thing on stable without "-Zshare-generics=y" in the cargo configuration file

[ghost]

Here's a bit more infos on my environment :
os / distro : linux / OpenSUSE Leap 15.2
kernel : 5.3.18-lp152.57-default
rustc : nightly-2021-01-10
IDE : Clion 2020.3
Bevy : v0.4

can anyone help me ?

[ghost]

I don't use wayland, I use xorg and xfce4

To be clear, before you fixed the "vulkan driver" problem, Bevy still ran your systems once without any error messages when you had DefaultPlugins registered? If so, did a window pop up?

[ghost]

No, I had no error at all and no window popping up at all, just that it ran once instead of in a loop as it should've

[cart]

That tells us a couple of things:

1. The WinitPlugin either failed to start up or wasn't registered
2. The WgpuPlugin never initialized an adapter, otherwise it would have failed

Are you disabling any features when you build bevy? Can you zip up your project and upload it here?

[ghost]

... I forgot to remove "default-features = false" from the Cargo.toml file ...

I've just retried with every features and now it works as intended
I feel really dumb, thanks !
