Of course I would like to get all other deprecation warnings to fix them, but for QNCM and network accessibility there is no way to fix them because the new QNetworkInformation class doesn’t exist in 5.15.Found https://www.kdab.com/un-deprecate-qt-project/ <https://www.kdab.com/un-deprecate-qt-project/>It seems we have many ways to deprecate, but not to undeprecate a specific one ? I’m looking for something similar to Q_UNUSED() to get rid of a -Wunused-parameter warning
Just a random note: that blog post of mine is a bit outdated. A few things have been changed in Qt's deprecation mechanisms in the meanwhile (warnings have been made versioned, deprecation warnings are enabled by default, and so on).
Anyway: there's unfortunately no solution to your issue except for disabling deprecating warnings altogether. For the record, I did propose to have special deprecation markers (special in the sense that you could enable/disable them independently from the other deprecation warnings) in Qt 5.15 for:
1) APIs that are deprecated in Qt 5 but without a replacement in Qt 5 itself (but eventually only in Qt 6), like indeed QNCM (AFAICT), so for which having a warning is "useless" as there's nothing one can do about it;
2) APIs that exist in Qt 5.15.x only to ease the transition towards Qt 6, i.e. are only meant to be used during a port, and absolutely not for "ordinary" development (like a lot of QStringView-related functionality in 5.15 which has been implemented by doing view.toString().foo(), i.e. throwing QStringView advantages out of the window).
The patches unfortunately were not merged before 5.15 was made closed source, so I gave up. You can find them in the relation chain here.
