Pyside6 6.6.1: References to QRingBuffer in private API are undefined

[DeadComposer]

I am trying to run a Pyside6 6.6.1 (with Qt 6.6.1) application on Linux. The libraries libQt6Network.so and libQt6SerialPort.so contain references to QRingBuffer in the private API (the specific symbol is _ZN11QRingBuffer6appendEPKcx@@Qt_6_PRIVATE_API) which are undefined. Oddly, libQt6Core.so contains a definition of _ZN11QRingBuffer6appendEPKcx but without the Qt_6_PRIVATE_API version identifier, so libQt6Network.so and libQt6SerialPort.so can't find that one. Could it be that Qt 6 was built without the private API on my system? Any help will be appreciated.

Hi,

How did you install PySide6 ?

@SGaist The system administrator installed Pyside6. I'll try to get more information from them about how it was done.
