The actual errors in the log are SDK related:

comment:ticket:59133:10 says this was fixed 2 weeks ago. You reported that you're using MacPorts 2.6.1. 2.6.2 was released a few days ago. Please run sudo port selfupdate, then try again.

[lplatter]

Upgrading to MacPorts 2.6.2 did not solve the problem. I am attaching the new log file

[lplatter]

log file for building with 2.6.2

[ryandesign (Ryan Carsten Schmidt)]

I see that you're using cctools with the +llvm80 variant. The cctools port only provides the Xcode 10 version. Since you're using Xcode 11, that might not be compatible. Try reinstalling the cctools port with the +xcode variant.

[lplatter]

That didn't resolve this issue.

gcc 9.4.0 is building without issue for me on 10.14, and on the 10.14 buildbot.

This appears to have been fixed.

please reopen with new information if this is still an issue.
