Gimmeapill [1] filed a deletion request for hdjmod [2]: This kernel module is deprecated and doesn't build anymore. The old DJ controllers supported by this module work with Mixxx using the udev + HID method: https://mixxx.org/wiki/doku.php/hercules_pc_dj_console So after 10y, this pkgbuild can finally be deleted ;-) [1] https://aur.archlinux.org/account/Gimmeapill/ [2] https://aur.archlinux.org/pkgbase/hdjmod/
