PySide 6.11 Build issue on macOS

[PremadeS]

Can't build PySide 6.11 on macos. It always gives this error

\[ 14%\] Building CXX object PySide6/QtCore/CMakeFiles/QtCore.dir/PySide6/QtCore/qdirlisting\_wrapper.cpp.o

Tried with:
AppleClang 14, 16, 17
llvm 14, 18 ,22
macos 14 x86_64, macos 26 arm64
Same error on all configurations

Shiboken6 and Shibken6 generator build fine. I can't figure out what is causing this. On linux its building smoothly

Following everything from the official guide results in same errors: https://doc.qt.io/qtforpython-6/building_from_source/macOS.html

SOLVED. It compiled using LLVM-20 and AppleClang-16
Seems like libclang version causes issues if it's anything other than version 20. I tried with LLVM-14, 18, 21 and 22 and it failed to compile on all of them
