MarsSeed [1] filed a deletion request for czmqpp-git [2]: Deprecated, defunct C++ wrapper for czmq 3 from 2016. This uses only the deprecated v3 API's of czmq and not any of the current v4 ones. Nothing depends on this package, and it is an orphan. Better to delete. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/czmqpp-git/
