Unfortunately, qttools fails to build with newer LLVM, some qdoc-related tests fail [1]. In particular, it misinterprets typedefs as structs, as can be seen in the build log [2]. Upstream Qt 6 had a series of patches to fix build with LLVM 16/17, see the linked Gerrit Reviews in this bug [3]. However, most of these patches fail to apply cleanly to 5.15 branch, and based on patch descriptions I could not identify the patch which would fix these particular test failures. So I either need a help from LLVM expert who would explain this test failure, or we can ignore these tests, or we can drop qdoc in 5.15. The last option would mean dropping documentation for all of Qt 5, and also fixing at least kuserfeedback and quickflux. It is hard to identify the complete set of affected packages, because some packages can depend on qdoc-qt5 indirectly via qttools5-dev-tools. Maybe the set of affected packages will become smaller once Qt6-based KDE stack lands in unstable.
