MarsSeed [1] filed a deletion request for srsgui-git [2]: Abandoned VCS package from 2018. Owner seems MIA since then. Build is broken: source needs Qt5 and Qwt, not legacy Qt4 and Qwt4. But better to delete this. 0 votes/comments. Arch [extra] carries latest stable srsgui. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/srsgui-git/
