qt6-doc currently only provides "Build with CMake", "Platform Integration" and "Reference Integration", which contains disabled links to the rest of Qt6 documentation. The documentation for qtbase, and all other modules, is currently missing from this port.
Thank you for your report! Could you find out what should be done to install missing docs?
(In reply to Max Brazhnikov from comment #1) Gladly, I've managed to build the missing docs by using the superrepository source structure. Either the all-in-one qt source download, or a makeshift imitation work. Building docs in a source superrepository using separate source tarballs: 1. Extract CMakelists.txt and cmake folder from qt-everywhere-src-6.10.2.tar.xz 2. Extract qtbase qtdeclarative qtdoc qttools tarballs. Rename the extracted folders to remove versioning. This is the bare minimum. You may add as many modules you want and their dependencies. 3. cmake -B build -G Ninja -DQT_HOST_PATH=/usr/local -DQT_BUILD_DOCS=ON 4. ninja docs Building docs with the all-in-one source tarball: Follow previous steps 3 and 4.
