AppImage working with JACK 2 aka. jackdmp1.99
First, this is a suggestion, not to be meant as complaining.
Since using the AppImage format (since musescore 2.0.3) musescore didn't work with the JACK2 transport layer. Look at the unsatisfying discussion here https://musescore.org/en/node/105361. I am not a nerd, but i couldn't let go and ( with a lot try and error) build my own AppImage from the sources. Unfortunately, there is no hint in the "Build from Sources" description, about the already existing possibility to build a portable AppImage direct from the sources. (of course to compile, link and install, "make" is more "nerdy" then install a package from the repositories)
A single command line instruction "make portable" will initialize the AppImage build, by creating the necessary directory "MuseScore.AppDir" and its contents. With the AppImageKit (which is an AppImage itself) i build my own MuseScore2.1.AppImage:
The Important thing is that this AppImage runs with the JACK2 transport layer. The good thing is, it proves MuseScore.AppImages could work with JACK2, the bad thing is (for me), it seems that whoever build the downloadable AppImages uses the JACK1 version. Ubuntustudio64, AV-Linux, Linux Mint have JACK2 in their repositories
Maybe the maintainers could reconsider their decision to not support the two JACK versions. (see https://musescore.org/en/node/105361). For those who use JACK2, MuseScore without JACK is a big step back.
Macht es Sinn das noch mal in deutsch zu posten ?
