Linux Fedora swift符号查找错误

Question

我试图在我的Fedora 22上快速工作。我遵循官方指示（https://swift.org/getting-started/#installing-swift）。 我能够使用快捷REPL并执行快捷文件，而无需与swift main.swift

swift.main内容编译它：

print("Hello, world!") 

当我尝试通过编译它： swiftc main.swift -o main 我会出现以下错误：

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

难道是因为二进制文件是针对Ubuntu的吗？或者我错过了什么？

在此先感谢！

正如您可能知道的那样，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。函数名不会随着我响起，所以我无法真正知道如何解决这些特定的错误。

我想在这一点上，你可能想尝试从源代码构建Swift，如下所述：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。即使你经历了这些错误，其他的事情也有可能在以后出现。

我还没有尝试从源代码构建Swift，所以不能真正分享任何经验。
