This copy of PyQt is unlicensed on macOS arm64

[Tom Goddard]

When I build ChimeraX on my Mac M1 computer with "make install-rbvi" to use the licensed wheels the build succeeds but it does not start. It gives the following error to the shell and exits:

This copy of PyQt is unlicensed.

Here is the successful PyQt install log output.

Does the same problem occur with Qt 6.3 that is in the current chimerax repository?

[Tom Goddard]

Yes same error with PyQt 6.3 wheels.

ChimeraX starts without this error when building on Intel Mac (descartes.cgl.ucsf.edu) running same macOS 12.3.1 with licensed wheels. So it seems to be specific to the Arm64 Mac build.

[Tom Goddard]

Building Mac arm64 ChimeraX

make install PYQT_LICENSE=commercial >& make.out

with PyQt 6.3.1 continues to generate this error and the build fails building the sphinx documentation and the app does not start

$ ~/ucsf/chimerax/ChimeraX.app/Contents/MacOS/ChimeraX
This copy of PyQt is unlicensed.

Apparently the license has not been included in the PyQt6 wheels on plato in the right way.

[Tom Goddard]

Here is a post discussing a similar problem.

​https://serveanswer.com/issue/generate-commercial-wheels-for-pyqt

[Tom Goddard]

The licensed PyQt6 wheels are on plato in /usr/local/src/PyQt6/6.3.1.

I think Greg is the only one who knows how to make these licensed wheels, although there are probably instructions online for how it is done.

[Tom Goddard]

I downloaded and tested the PyQt 6.3.1 commercial Mac wheels with the standard Python.org 3.9.11 python following the Riverbank instructions

​https://www.riverbankcomputing.com/static/Docs/PyQt6/installation.html#installing-the-commercial-version

and got the same error. So I sent the following email to Riverbank support.

Subject: Commercial PyQt6 gives "This copy of PyQt is unlicensed" on Mac M1

To: support@riverbankcomputing.com

I am trying to use my commercially licensed PyQt6 on a Mac M1 machine.  The commercial wheels from Riverbank install without errors but then importing gives the error "This copy of PyQt is unlicensed."  The exact same process on an Intel Mac works and does not give any error when PyQt6 is used.  How do I get the commercial wheels to work on Mac M1?

 Thanks for your help.  I have been using commercial PyQt for 6 years and appreciate your effort.

[Greg Couch]

The licensed wheels, that we used to build, are for bundling the Qt binaries so there is only one wheel. Now, we're using the PyQt6-Qt6 wheel for the Qt binaries from PyPi, and that allows us to use the PyQt6_commercial wheel, that we download, unaltered.

[Greg Couch]

Fixed by Riverbank after prodding from Tom Goddard.
