So, I was reading https://cinelerra-gg.org/download/CinelerraGG_Manual/Build_CinGG_AppImage_fr... I already had pre-build static/opevpl cingg in /dev/shm/new-git/cinelerra/cinelerra-5.1 so I cd there cd tools wget https://github.com/AppImage/AppImageKit/releases/download/continuous/appimag... (note, for x86_64 name will be different!) chmod +x appimagetool-i686.AppImage cd ../ guest@slax:/dev/shm/new-git/cinelerra/cinelerra-5.1$ setarch i686 ./bld_appimage.sh on x86_64 you obviously can skip setarch part it was a bit scary because it re-run configure with its own parameters, but at the end it just sailed past build phase and packaged resultin binaries in cinelerra-5.1/bin as cin-i386.AppImage so, in general procedure works, I think, just make sure you have makesquashfs installed ?
