[FIXED] Why is this PySide2 build failing to find a generated C++ wrapper?

Issue

I'm trying to build the latest release of PySide2 on MacOs Sierra 10.12.2 (16C67) with python 3.6. As of now, the build invoked with

python3 setup.py build

is failing with the following error: (I have substituted my name out of my home directory...)

clang: error: no such file or directory: '/Users/myusername/pythonpackage/pyside-setup/pyside3_build/py3.6-qt5.8.0-64bit-release/pyside2/PySide2/QtCore/PySide2/QtCore/qabstractstate_wrapper.cpp'

I am using Qt 5.8 as installed by homebrew.

I have looked through the build log and cannot find where/if that file is generated, as I am not familiar with the binding generation. Using PyQt is not an option, as its license is not applicable to my application.

Why is this source missing, and what can I do to make the build succeed?

PySide2 was installed from this repo: git://code.qt.io/pyside/pyside-setup.git

Solution

Turns out I stated the issue in the actual question: The PySide2 README states that it supports Qt 5.5 and 5.6. I was trying to use 5.8.

I solved my problem by using an old homebrew qt installed via:

curl -O https://raw.githubusercontent.com/Homebrew/homebrew-core/fdfc724dd532345f5c6cdf47dc43e99654e6a5fd/Formula/qt5.rb
brew install ./qt5.rb

followed by the build invocation, and it worked.
