A GitLab upgrade is scheduled for Monday, June 2, 2025. The service will be unavailable for a few minutes in the morning. We'll keep you posted on the progress of the upgrade on the Mattermost channel: https://mattermost.inria.fr/devel/channels/gitlab. We recommend that you do not work on the platform until an announcement indicates that maintenance is complete.
Otherwise, the build fails with the following error:
.../src/src/interface/Node_select.cpp:254:46: error: missing template arguments before ‘(’ token
254 | reassign_children_rec(*it, QFlags(Qt::Unchecked));
| ^(at least on Debian with Qt 5.15.2)
