warning: implicitly-declared ??
-
After new download / install of 5.12.12 I am getting hundred of the following warnings :
/home/qy/Qt/5.12.12/gcc_64/include/QtWidgets/qstyleoption.h:588: warning: implicitly-declared ‘QStyleOptionComplex& QStyleOptionComplex::operator=(const QStyleOptionComplex&)’ is deprecated [-Wdeprecated-copy] ../../../../5.12.12/gcc_64/include/QtWidgets/qstyleoption.h: In member function ‘QStyleOptionComboBox& QStyleOptionComboBox::operator=(const QStyleOptionComboBox&)’: ../../../../5.12.12/gcc_64/include/QtWidgets/qstyleoption.h:588:24: warning: implicitly-declared ‘QStyleOptionComplex& QStyleOptionComplex::operator=(const QStyleOptionComplex&)’ is deprecated [-Wdeprecated-copy] 588 | class Q_WIDGETS_EXPORT QStyleOptionComboBox : public QStyleOptionComplex | ^~~~~~~~~~~~~~~~~~~~ ../../../../5.12.12/gcc_64/include/QtWidgets/qstyleoption.h:510:5: note: because ‘QStyleOptionComplex’ has user-provided ‘QStyleOptionComplex::QStyleOptionComplex(const QStyleOptionComplex&)’ 510 | QStyleOptionComplex(const QStyleOptionComplex &other) : QStyleOption(Version, Type) { *this = other; } | ^~~~~~~~~~~~~~~~~~~My code still works, but even removing all warning in .pro file I still get the above.
I am tempted to "downgrade" to next to last 5 version, but like to know / get confirmed it would be worth a while... -
It's a deprecation warning coming from compiler, not from Qt. You can safely ignore it.

If you do want to make sure the warning goes away it's probably better to upgrade to Qt 5.15 or 6 which are better prepared for new compiler warnings introduced in recent years.

@sierdzio I have disabled compiler warnings and still getting these. Warnings do no bother me but when I get real error it is a pain to scroll thru the warnings to get to it. Yes, I am adding 6.2.2. - hope it will make these disappear.
Cheers
