I've been informed that kdesu is not intended to be built for Mac or Windows.
It's for Linux and *BSD only.

Comment 2 Yurii Kolesnykov 2022-03-01 13:37:42 UTC

How many *BSDs have all of this syscalls except FreeBSD?

Comment 3 Yurii Kolesnykov 2022-03-01 13:40:30 UTC

And macOS is largely derived from original BSD with some later updates and backports.
