Log file of failed qt56-qtbase build

[MarcusCalhoun-Lopez (Marcus Calhoun-Lopez)]

In a499a38fd9cdfdc9cdf06622bcad2c73c4e5112b/macports-ports (master):

qt5*-qtbase: don't duplicate Clang provided library

Qt assumes that Intel's Intrinsics are not provided by Clang.
This assumption is incorrect for recent versions of Clang.
See

​https://github.com/llvm/llvm-project/commit/e54093fcc0a651df14040a61fc8efdd338389afa

Fixes #59364

Thanks for the fix, however, there still seem to be problems:

I can no longer reproduce this problem.

Looking through your log file, however, makes me think there is a different problem.
ICU was recently updated, and that seems to be ​affecting your build.
My suggestion is to run:

• sudo port selfupdate
• sudo port upgrade outdated
• sudo port clean qt56-qtbase
• sudo port install qt56-qtbase

If the problem persists, please post the new log.

[lemzwerg (Werner Lemberg)]

It now worked. Thanks!

See #62051: the fix used was not sufficient for Xcode 11.4 (which is based on LLVM clang 9.0) and later.
