Is it possible to build PySide2 for M1 (arm64)?

[carlos-villavicencio]

I’m trying to build my project dependencies for native Apple Silicon support. However, I’m having issues compiling PySide2. I know… I know… it’s too old and it’s better to use PySide6. We want to upgrade that too. But my point is to know if I can do the arm64 support first.

To build PySide2 I’m using:

• macOS 12.6
• XCode 14
• I compiled Python 3.9 with no issues.
• QT 5.15.10
• libclang 12
• pyside-setup (source code) 5.15.2.1

My error message when I try to build PySide2 with python setup.py install --qmake=... is:

Something's broken.  UCHAR_MAX should be defined in limits.h.

I realized that since QT 5.15.4 I can use the option QMAKE_APPLE_DEVICE_ARCHS="x86_64 arm64" but I’m not sure how to pass it to pyside-setup.

I have a couple of questions:

1. Is it possible to compile PySide2 (QT5) for arm?
2. How can I build PySide2 locally without a Qt license just for development purposes? I have my file only on CI and when I try locally I get:

Error: Qt license file was not found! Project ERROR: License check failed! Giving up ... error: Failed to query for Qt's QMAKE_MACOSX_DEPLOYMENT_TARGET.

@carlos-villavicencio hi, did you find solution? Also how did you build pyside2 from source?

Hi,

Since Qt 5.15.2 contains only x86_64, one thing you can do is start a shell with the arch command so that it runs in x86_64 mode and from there follow the build instructions.
