Linux 无法生成Objective-C模块'；CGtk&x27；

我正在尝试在archlinux中使用swift。在尝试用Gtk构建一个简单的项目时，我遇到了一些错误。下面是我的Package.swift文件：

import PackageDescription

let package = Package(
    name: "SwiftGtkApplication",
    dependencies: [
        .Package(url: "https://github.com/TomasLinhart/SwiftGtk", majorVersion: 0, minor: 2)
    ]
)

import SwiftGtk

let app = Application(applicationId: "com.example.application")
app.run { window in
    window.title = "Hello World"
    window.defaultSize = Size(width: 400, height: 400)
    window.resizable = true

    let button = Button(label: "Press Me")
    button.clicked = { _ in
        let newWindow = Window(windowType: .topLevel)
        newWindow.title = "Just a window"
        newWindow.defaultSize = Size(width: 200, height: 200)
        let labelPressed = Label(text: "Oh, you pressed the button.")
        newWindow.add(labelPressed)

        newWindow.showAll()
    }

    window.add(button)
}

以及main.swift文件：

import PackageDescription

let package = Package(
    name: "SwiftGtkApplication",
    dependencies: [
        .Package(url: "https://github.com/TomasLinhart/SwiftGtk", majorVersion: 0, minor: 2)
    ]
)

import SwiftGtk

let app = Application(applicationId: "com.example.application")
app.run { window in
    window.title = "Hello World"
    window.defaultSize = Size(width: 400, height: 400)
    window.resizable = true

    let button = Button(label: "Press Me")
    button.clicked = { _ in
        let newWindow = Window(windowType: .topLevel)
        newWindow.title = "Just a window"
        newWindow.defaultSize = Size(width: 200, height: 200)
        let labelPressed = Label(text: "Oh, you pressed the button.")
        newWindow.add(labelPressed)

        newWindow.showAll()
    }

    window.add(button)
}

我无法使用

swift build

构建它：

gtk和clang都已安装。我做错了什么？

这是一个简单的问题，正确地指向SPM文件中的CGtk项目，其中包含：

.Package(url: "https://github.com/TomasLinhart/CGtk-Linux", majorVersion: 1, minor: 3),

面对同样的问题，请让我们知道您是否可以解决此问题。现在，我的fork中正在正确构建此问题，请转到并将SPM中的链接更改为它。应该说这是Swift 4.1。
