Just as a reminder, the "C++20 is mandatory for users of Qt (Phase III)” (https://bugreports.qt.io/browse/QTBUG-109362) says "The tentative plan is Qt 6.12+”
and "C++20 is required for the development and buiding of Qt itself (Phase II)” (https://bugreports.qt.io/browse/QTBUG-109361) - "The tentative plan is Qt 6.9-6.11” With all the respect to the power of C++20 and enthusiasm to use it from Qt Project developers, what should we expect from all other users if we would make this change in 6.8, considering: a) just 4 months left to the Feature Freeze for 6.8 b) there is zero communication to users beyond the above issues on Qt But Reports and discussions on this mailing list (which is actually for Qt developers and not Qt users, BTW) c) there is no other communication about the done and ongoing works introducing C++20 in Qt and plans for future versions, beyond the talk from Mark at QtWS22 and careful reading of “What’s New” pages Qt crashed such a change on users with C++11 and with C++17 in the past. Each time after this, there were much more negative responses than “thank you”s. I still hope we find a way to do this better this time. And just “faster” is not “better" In the current shape, my vote is “no”. -- Vladimir On 3.

What's the current state for those, for supporting Qt 6.8 or 6.9? We have VxWorks coming in and I'd like it to meet a higher minimum bar than "legacy". That is, I'd like VxWorks to require a C++20-compliant compiler before being enabled in our CI, but that's only fair if we have a line-of- sight to bringing everyone to C++20. -- Thiago Macieira - thiago.macieira (AT) intel.com Cloud Software Architect - Intel DCAI Cloud Engineering -- Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
