I see some discussion in the ticket on Qt 6.0. This is a case where you will need both Qt 5 and Qt 6 in parallel for potentially years, similar to the situation with GTK 2 and GTK 3 or Qt4 and Qt5.
I predict very slow adoption of Qt 6 because they have deferred a lot of modules that are not expected until 6.2 in the fall of 2021 or later and they expect to repackage some classes into other modules. The two that affect me are qtmultimedia and qtwebengine. I had some trouble getting the directory layout the way I wanted it with cmake because it doesn't allow "..". -DCMAKE_INSTALL_PREFIX=/usr -DINSTALL_BINDIR=/usr/lib/qt6/bin -DINSTALL_DATADIR=/usr/share/qt6 -DINSTALL_DOCDIR=/usr/share/doc -DINSTALL_INCLUDEDIR=/usr/include/qt6 -DINSTALL_LIBDIR=/usr/lib -DINSTALL_LIBEXECDIR=/usr/lib/qt6/libexec -DINSTALL_MKSPECSDIR=/usr/lib/qt6/mkspecs -DINSTALL_PLUGINSDIR=/usr/lib/qt6/plugins -DINSTALL_QMLDIR=/usr/lib/qt6/qml -DINSTALL_SYSCONFDIR=/etc/xdg I don't plan to convert any code I work on to it or install any of it until something I build needs it or they ship qtmultimedia and qtwebengine. -- http://lists.linuxfromscratch.org/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
