Hi Paul, this build failure is fixed in version 6.2.4+dfsg-4 of qt6-declarative (https://buildd.debian.org/status/package.php?p=qt6-declarative&suite=experimental). The package is currently in experimental, because it will very soon be part of the Qt 6.2.4 transition and that should solve the issue. -- Med vänliga hälsningar Patrick Franz
