我正在尝试从 Ubuntu 上的 swift 源代码构建一个静态链接的可执行文件。
叫
swift build -Xswiftc -static-stdlib
如使用静态 Swift 核心库编译 Swift 脚本中所建议的
返回此错误：
/usr/bin/ld.gold: error: cannot find -lFoundation
一些有根据的猜测：研究这个并没有让我走得很远，我知道这意味着找不到图书馆。也许它不在编译器的路径中？
完整的错误消息：

问题是 Foundation 不能用作静态库。 有一个开放的错误：
https://bugs.swift.org/browse/SR-2205
如果你可以构建一个静态的基础库，例如作为从源代码构建 Swift 的一部分，你也许能够解决这个问题。
