@Richard, thank you very much for pointing this out. I tried flatpak image and this time with luck.

"the idea of the AppImage was (?) the images are self contained"

the AppImage is self-contained only insofar as enough of the libraries are included, evidently not enough for these newer distros. I haven't got a current way of building these AppImages, but the flatpak version is being maintained...

Same story with openSUSE 15.3 and I even cannot find this version of the library in the repo, I only see version 7.

Besides, the idea of the AppImage was (?) the images are self contained, so I am a bit puzzled here over host system dependency.

On Debian stable I am getting the same error message running the AppImage built when libffi was on version six. I've rebuilt the appimage to include the current libffi that is in Debian stable, version 7, and the appimage after build ok fails to execute with this message

Denemo data expected in /tmp/.mount_denemopoVnee/share/denemo
Uncaught exception:

Error while printing exception:
Key: stack-overflow, args: (#f "Stack overflow" #f #f)

It sounds like if I could copy libffi version six into the appimage then it might work, but I don't know how to get hold of the files to copy...

Running Ubuntu 20.04, I grabbed a copy of the AppImage, made it executable, and was met with the error:

./bin/denemo: error while loading shared libraries: libffi.so.6: cannot open shared object file: No such file or directory

It looks like the system libffi version (for Ubuntu 20.04 and presumably later) is 7, and the AppImage depends on the system having version 6 installed.  Perhaps this dependency can/should be part of the AppImage itself?  Not sure, as it looks like this might actually be part of a larger issue with Ubuntu 20.04 shipping a broken installation of Python:


Regardless, I was able to get the AppImage to launch after manually downloading and installing an outdated libffi6 package, but wanted to report the problem anyway, in case it would be an easy fix for the package maintainer(s).  :)
