即使存在于 Cargo.toml 中，也缺少 crate 错误

Question

我有一个使用介子的基本 gtk-rs 项目。 我在 Cargo.toml 文件中包含了 gtk4 crate。 当我使用货物运行时，它编译但输出“分段错误”错误（我已经搜索过，但我仍然不知道那是什么）。 但是，当我与介子一起运行时，它根本拒绝构建。

builddir/
 main.p/
 build.ninja
src/

 ...
Cargo.toml
Cargo.lock
meson.build

Cargo.toml

[package]
name = "my-gtk-app"
version = "0.1.0"
edition = "2018"
[dependencies]
gtk = { version = "0.2", package = "gtk4" }

介子构建

project(
  'my-gtk-app',
  'rust',
  version : '0.1',
)
cargo_sources = files(
  'Cargo.toml',
  'Cargo.lock',
)
gtk = dependency('gtk4', version: '>= 4.0.0')
executable('main', 'src/main.rs', dependencies : gtk)

主文件

use gtk::prelude::*;
use gtk::{Application, ApplicationWindow};

fn main() {
    let app = Application::builder()
        .application_id("org.example.HelloWorld")
        .build();

    app.connect_activate(|app| {
        // We create the main window.
        let window = ApplicationWindow::builder()
            .application(app)
            .default_width(320)
            .default_height(200)
            .title("Hello, World!")
            .build();

        // Show the window.
        window.show();
    });

    app.run();
}

当我使用cargo run运行程序时，我得到

Finished dev [unoptimized + debuginfo] target(s) in 0.45s
Running `target/debug/my-gtk-app`
1] 73039 segmentation fault  cargo run

但是，当我使用meson compile -C builddir运行时，我得到

Some errors have detailed explanations: E0432, E0433.

如果有帮助，我在 MacOS 上。
