Swift 包管理器：软件更新后静态构建失败

Question

问题描述

自从我更新 Xcode 后，我正在处理的一个项目没有构建。请注意，我正在使用 swift 构建（而不是 Xcode）构建可执行文件。

详情

失败的命令是： swift build -Xswiftc -static-stdlib -Xswiftc -DDEBUG

我正在尝试构建静态。只要尝试 swift build，就可以了。

错误

我只复制错误输出的开头（其余太长）：

Package.swift

请注意，为了匿名起见，我已经重命名了项目和库名称。

// swift-tools-version:4.0
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "PROJECT",
    dependencies: [
        // Dependencies declare other packages that this package depends on.
        // .package(url: /* package url */, from: "1.0.0"),
        .package(url: "../Lib1", .branch("master")),
        .package(url: "../Lib2", .branch("master")),
        .package(url: "../Lib3", .branch("master")),
        .package(url: "../Lib4", .branch("master")),
    ],
    targets: [
        // Targets are the basic building blocks of a package. A target can define a module or a test suite.
        // Targets can depend on other targets in this package, and on products in packages which this package depends on.
        .target(
            name: "PROJECT",
            dependencies: ["Lib1", "Lib2", "Lib3", "Lib4"]),
    ]
)

Swift更新后的版本

运行

swift -version

在命令行中 returns :

Apple Swift version 5.0 (swiftlang-1001.0.69.5 clang-1001.0.46.3)
Target: x86_64-apple-darwin18.2.0

Answer 1

Swift 由于 ABI 稳定性，5.0 不再支持 Apple 平台上的静态链接。因此，如果您删除 -Xswiftc -static-stdlib 并且代码有效 Swift 5.0.

，构建应该可以正常工作

Answer 2

新版本的 MacOS 不支持静态构建。在这里查看答案：
