如何从命令行编译Swift以进行分发

我有一个单一文件
Swift命令行脚本(它在给定进程ID的情况下转储菜单栏的内容).
要了解我正在使用的API,这里有几个相关的行： import Foundation
import Cocoa
// ...
func getAttribute(element: AXUIElement,name: String) -> CFTypeRef? {
var value: CFTypeRef? = nil
AXUIElementCopyAttributeValue(element,name as CFString,&value)
return value
}
// ...
var app: NSRunningApplication? = nil
if pid == -1 {
app = NSWorkspace.shared().menuBarOwningApplication
}
else {
app = NSRunningApplication(processIdentifier: pid)
}
// ...
let axApp = AXUIElementCreateApplication(app.processIdentifier)
整个文件可用here. 当我使用swiftc menu.swift编译它时,我可以在安装了Swift的系统中运行它. 当我将菜单可执行文件共享给没有Swift的人时,他们通过终端运行时会出现以下错误： Code 6: dyld: Library not loaded: @rpath/libswiftAppKit.dylib Referenced from: ./menu Reason: image not found 我想我需要静态链接一些东西,但我不确定.我无法轻松测试,因为没有Swift,我无法访问macOS构建. 我如何使用swiftc以便我可以编译我的脚本以便它可以在任何macOS系统上运行？ 解决方法
对于仅使用-static-stdlib的标准库的情况,可以解决此问题.
当您编译没有选项的脚本时,最终的可执行文件包含各种Swift标准库的rpath,您可以使用otool验证它们. > swiftc menu.swift
> otool -L menu
