在Ubuntu上使用Swift构建静态链接的可执行文件

Question

我正在尝试从Ubuntu上的快速源构建静态链接的可执行文件。

呼唤

swift build -Xswiftc -static-stdlib

如编译带有静态Swift核心库的Swift脚本中所建议

返回此错误：

/usr/bin/ld.gold: error: cannot find -lFoundation

一些有根据的猜测：研究这一点并没有使我走的太远，我知道这意味着找不到该库。也许它不在编译器的路径中？

完整的错误消息：

问题是 Foundation 不能作为静态库使用。有一个未解决的错误：

https://bugs.swift.org/browse/SR-2205

如果您可以构建一个静态 Foundation 库，例如作为从源代码构建 Swift 的一部分，您也许可以解决这个问题。
