I am using a commit to avoid this problem https://github.com/KDAB/cxx-qt/issues/850.

Thanks for taking the time to report this issue, so somewhere it is looking for rust::cxxqtlib1::QMetaObjectConnection instead of rust::cxxqt1::QMetaObjectConnection. These were renamed at one point, so either one has been missed or when using the Qt 6.7 patch fix you have partial changes.

Are you able to try the backports branch for 0.6.1 in your cargo.toml to see if it helps

With that branch it compiles.
