Linux Fedora swift符號查找錯誤

Question

我試圖在我的Fedora 22上快速工作。我遵循官方指示（https://swift.org/getting-started/#installing-swift）。 我能夠使用快捷REPL並執行快捷文件，而無需與swift main.swift

swift.main內容編譯它：

print("Hello, world!") 

當我嘗試通過編譯它： swiftc main.swift -o main 我會出現以下錯誤：

難道是因爲二進制文件是針對Ubuntu的嗎？或者我錯過了什麼？

在此先感謝！

正如您可能知道的那樣，這些錯誤表明Swift需要一些符號，很可能是函數，但在任何正在使用的庫中都不可用。函數名不會隨着我響起，所以我無法真正知道如何解決這些特定的錯誤。

我想在這一點上，你可能想嘗試從源代碼構建Swift，如下所述：https://github.com/apple/swift/blob/master/README.md。在Fedora上使用Ubuntu二進制文件可能不是一個好主意。即使你經歷了這些錯誤，其他的事情也有可能在以後出現。

我還沒有嘗試從源代碼構建Swift，所以不能真正分享任何經驗。
