- Releases now include Midi-Harbor-<version>-<x86_64|aarch64>.AppImage, built from the same binary as the packages and listed in checksums.txt, for distributions without a .deb or .rpm. Opened with no arguments it shows the window, and the daemon it registers runs under the systemd user unit like a package install. - service install run from an AppImage registers the .AppImage file instead of the executable inside the runtime's temporary mount, which is gone once the process exits. The file is used only when the running executable is inside APPDIR, so a program started from another AppImage, whose APPIMAGE it inherits, still registers itself. - The AppImage carries only the Avahi client libraries from the Debian 12 sysroot, with their LGPL-2.1 license, found through the binary's RUNPATH rather than LD_LIBRARY_PATH; glibc 2.35 or newer, ALSA, D-Bus and libxkbcommon come from the host, as for the packages. - Its AppRun starts the binary as midi-harbor, so on X11 the window's class matches the desktop entry instead of the AppImage's file name. - Building it needs the cross image's new patchelf, file, appimagetool 1.9.1 and type2 runtime 20251108, pinned by checksum, and a sysroot rebuilt to carry Avahi's license; the script stops and names make build-sysroot when that license is missing.

# The AppImage is Midi-Harbor-<version>-<x86_64|aarch64>.AppImage in the output directory. It
|
|
# needs patchelf, appimagetool, the AppImage runtime for the target in
|
|
# /usr/local/share/appimage/runtime-<x86_64|aarch64>, and the Debian 12 sysroot the binary was
|
|
# linked against in /sysroot/linux_<arch>; the image packaging/cross/Dockerfile makes has the
|
|
# tools, and GoReleaser runs it there with the sysroots mounted. MIDI_HARBOR_SYSROOT names another
|
|
# directory holding the sysroots.
|
|
#
|
|
# Started with no arguments the AppImage opens the graphical interface, and `service install` run
|
|
# from it registers the AppImage file itself, so systemd mounts it again at every start
|
|
# (specs/017-appimage).
|
|
#
|
|
# It bundles only the Avahi client libraries, which a desktop may lack. glibc, ALSA, D-Bus and
|
|
# libxkbcommon come from the host: a bundled libasound finds no sound cards, and the host's
|
|
# libxkbcommon-x11, which the interface loads while it runs, is built against the host's
|
|
# libxkbcommon (R-104).
