Is this on CDD or some other system? I'm not sure why that library isn't present, as it's part of the standard Swift library package, as far as I understand it...

Actually, looks like that may no longer be needed. I am going to try things out with that removed sometime today.

I downloaded the repo today and I got the ld: library not found for -lrt. I'm on a Mac with macOS 12.6.3 and XCode 14.2 (14C18).

Hello @shepazon I pulled the code today and still have a similar error:

What does CDD mean? I am using iMac with MacOS 13.3 (22E252)

这是什么CDD意思？我正在使用配备 MacOS 13.3 (22E252) 的 iMac

你那个library not found for -lrt 问题解决了 吗？

[shepazon]

Fixed long ago.
