AppImage is too fat

[Samueru-sama]

Any reason you are not using the debloated packages from here?

https://github.com/pkgforge-dev/Anylinux-AppImages/blob/e861e2adf25d60691793349d1069bc285a0feeb7/useful-tools/demo/qt6-dbus-demo-appimage.sh#L40-L42

They will:

• get rid of the 150 MiB libLLVM.

• get rid of 30 MiB libicudata.

• get rid of the 20 MiB libx265.

And there is some more like kiconthemes-mini which remove the bundled breeze icon theme from libKF6BreezeIcons.so (25 MiB), yes KDE now does this of shipping the entire icon theme in a lib to guarantee they always have the needed icons, it really depends on the app since some apps really need specific icons provided by the breeze theme (like kdenlive).

I built the appimage on my personal system.

I just tried to make a build using a container, but on an Arch container python with pyside6 just coredumps for no apparent reason, and with that the package ends up incomplete.

Coredump

I see

I actually would not rely on the strace mode to get you all the libraries. In other words it is not needed that the application needs to open.

In these cases you have to pass a few Qt libs manually so that it triggers the correct deployment steps: https://github.com/pkgforge-dev/anki-AppImage/blob/186e0ad550a5e8b5a4f72c9365ceb36391a5942a/make-appimage.sh#L19-L24

This is only needed for python apps, due to the fact that you cannot ldd a python script lol

I was only able to cut down the size to ~70MiB. pyside6 doesn't seem to like qt6-base-mini as it fails to import some modules with it. And kiconthemes-mini seems to break system accent color detection.

But the new AppImage also coredumps in my distrobox containers, likely for the same reason as why the app itself doesn't launch on an Arch container. I remember it working before, so either the new Qt or pyside version broke it or it's something with Arch packaging.
