Created attachment 111190 [details] (Temporary patch) I'm the Adélie Linux KDE maintainer, and we can't make a package of kalarmcal as shipped since the transition to KHolidays being a Framework package: CMake Error at CMakeLists.txt:44 (find_package): Could not find a configuration file for package "KF5Holidays" that is compatible with requested version "5.7.2". The following configuration files were considered but not accepted: /usr/lib/cmake/KF5Holidays/KF5HolidaysConfig.cmake, version: 5.6.2 I've temporarily patched it to accept 5.6.2, since that is the latest ABI version for KHolidays now (even in git master).
You need to use a matching kholidays-17.12.2 (also part of kde applications with kalarmcal)
Sorry, I misunderstood, re-opening while I confirm.
Confirmed it works with kholidays-5.43.0 (and 5.44.0 available to distro packagers), reports itself as version: 5.43.0 , which satisfies >= 5.7.2
I see the problem; the package manager was seeing stale 17.08.2 in repo and it figured that was higher number than 5.43.0. Sorry for the noise.
