Question

我正在尝试快速处理我的Fedora 22.我遵循了官方指示（https://swift.org/getting-started/#installing-swift）。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 content：

print("Hello, world!")

当我尝试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，因为二进制文件适用于Ubuntu？或者我错过了什么？

提前致谢！

正如您可能知道的那样，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。函数名称并没有响铃，所以我无法确定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。即使您已经过了这些错误，也可能会在以后出现其他问题。

我还没有尝试过从源头构建Swift，因此无法真正分享任何经验。
