two error with files in generated_cpp dir.

[inportinitial]

I'm not quite sure which aspects are the key points for developers, so I apologize for any excessive or incomplete information I've provided. (qwq)

environment:

window11 x64 python 3.12 qt6.8.0 nmake

error 1 (i can solve) : )

repeated function declaration in generated_cpp\com_trolltech_qt_core_builtin\com_trolltech_qt_core_builtin0.h and .cpp

in file generated_cpp\com_trolltech_qt_core_builtin\com_trolltech_qt_core_builtin0.h,and com_trolltech_qt_core_builtin0.cpp,
Regarding some of __ eq __ and __ ne __ functions, both the function declarations in the header file (.h) and the function definitions in the source file (.cpp) appear twice identically, leading to errors of duplicate function declarations and definitions.

solution

My solution was to identify these duplicate functions and delete one of each pair.

error 2 (i can't solve QAQ)

when i do nmake for extensions,it is reported that QCborMap and QJsonObject are being used incorrectly. I haven't found a solution for this issue.

Thanks! PythonQt does not yet support Qt 6.8 - this needs some changes in the preprocessor, which may take a bit.
Until then you are stuck with Qt 6.7 (hopefully not long).
