Closed issue by VoidDuck on void-packages repository https://github.com/void-linux/void-packages/issues/18250 Description: Hello, I need to build qjackctl from source, because the version from the void repository comes without ALSA sequencer support (I don't know why by the way). Although jack, jack-devel and libjack are installed, qjackctl refuses to build telling me the jack library cannot be found. I looked for a possibly existing libjack-devel package in the repository but there is nothing like that. I suppose it is missing. I had no problem building qjackctl a few months ago on another void system. I tried to build the same version I did at that time and it failed as well, so I'm sure the problem comes from void, where something must have changed since then. ### System * xuname: *Void 5.4.10_2 x86_64 GenuineIntel uptodate rF* * package: *libjack-1.9.14_1*
