Linux Fedora swift 符号查找错误

Question

我正在尝试让 swift 在我的 Fedora 22 上运行。我已按照官方说明 (https://swift.org/getting-started/#installing-swift) 进行操作。我可以使用 swift REPL 并执行 swift 文件，而无需使用 swift main.swift

进行编译

swift.main内容：

print("Hello, world!")

当我试图通过以下方式编译它时： swiftc main.swift -o main 我收到以下错误：

[christian@roodrallec Sources]$ swiftc main.swift -o main -v

是吗，因为二进制文件是针对 Ubuntu 的？或者我错过了什么？

提前致谢！

Answer 1

您可能知道，这些错误表明 Swift 需要一些符号，很可能是函数，但在任何正在使用的库中都不可用。函数名称并没有引起我的注意，所以我真的不知道如何解决这些特定错误。

我认为此时您可能想尝试从源代码构建 Swift，如此处所述：https://github.com/apple/swift/blob/master/README.md。在 Fedora 上使用 Ubuntu 二进制文件可能不是一个好主意。即使您克服了这些错误，以后也可能会出现其他问题。

我还没有尝试从源代码构建 Swift，因此无法真正分享这方面的任何经验。
