[pyqtdeploy] Failing at building the demo

Fri Mar 8 18:38:17 GMT 2024

To complement Charles' answer, it seems like someone found a quick fix with
GCC11, in case you are reluctant to move back to GCC10:
https://forum.qt.io/topic/136672/error-installing-qt-everywhere-src-5-15-2-on-ubuntu-22-04/2

add these 3 lines at the top of qtbase/src/corelib/global/qglobal.h : (I
haven't tested that)
```
#ifdef __cplusplus
#include <limits>
#endif
```

For ref, the QT bug associated is:
https://bugreports.qt.io/browse/QTBUG-90395
It has been fixed for QT5.15.9
<https://bugreports.qt.io/issues/?jql=project+%3D+QTBUG+AND+fixVersion+%3D+5.15.9>,
but since you are using the default QT5.15.2, well it's not fixed.

Best regards,

KC
