Source: libical3 Version: 3.0.20-1 Tags: patch User: [email protected] Usertags: ftcbfs
libical3 fails to cross build from source. Quite recently, vapigen was updated (#1061107) to better support cross compilation by adding a triplet-prefixed wrapper. Using this wrapper (and the valac wrapper) is a key ingredient to making libical3 cross buildable. As the upstream CMakeLists.txt uses find_program directly, I propose supplying those wrappers explicitly. In a more distant future as the wrappers become more widely accepted, we might update the upstream build system to prefer them over bare tools. The other aspect is running gtk-doc, which is something that never works in cross builds. Fortunately, we can just disable it in arch-only builds as the documentation is cleanly separated. I verified that turning off gtk-doc does not change binary artifacts by comparing builds for reproducibility. I'm attaching a combined patch for your convenience. Helmut
