Hi, I have just committed https://phabricator.kde.org/D21495 for kcalc. It adds a required dependency to MPFR library for the upcoming 19.08 releases.
Unfortunately I didn't expect the CI to not have this dependency, so right now it fails to build for openSUSE (but works for FreeBSD). https://build.kde.org/job/Applications/job/kcalc/ Sorry for not checking earlier. -- Christoph Feck KDE Release Team
