kdenlive-24.02.0_A-x86_64.AppImage doesn't work on porteus 5.01 ( slackware 15 based distr)

Kdenlive 23.08.2 released

Hi, Since I haven’t seen anyone else post the resolution to this yet, but lots of people banging their heads against it: I assume it’s related to the updates to the kde build farm that were mentioned around the time of the 23.08.2 release. The missing GLIBCXX symbols are because that release’s appimage was built with a newer libc than had been used previously and that ships with Debian 11 and derived distro releases. You’ll need to update to Debian 12 to use this appimage. HTH, Ron

kdenlive-23.08.3-x86_64.AppImage not working either

Yes, this is very likely going to be true for all future releases unless the build environment is downgraded, or whatever is generating code in the appimage which uses symbols from a libstdc++ release later than the one in Debian 11 et. al. stops doing that (and both those things are most probably Backward Steps in the Overall Scheme Of Things). It’s not a “bug” in kdenlive introduced by the kdenlive developers, or likely one they can “fix” in kdenlive - it’s an artifact of building the appimag…

The problem isn’t that you’re missing libstdc++.so.6, it’s that your distro has an ancient version which is missing symbols the Appimage needs.

You either need to update your distro, or use an older appimage.
