Debug "cannot open shared object file: no such file or directory"

[carlonluca]

Hello! I'm experimenting with appimage-builder a bit. I built an example app with appimage-builder and I'm testing it on some older systems. My AppImage seems to run on Manjaro and on Fedora 22. I then tested on Ubuntu 13 and I'm getting this error:

/tmp/.mount_Fall-l8kxOCl/usr/bin/Fall: error while loading shared libraries: libQt6Core.so.6: cannot open shared object file: No such file or directory

I therefore tried to investigate why the library is not found, as it seems to be there:

ubuntu@ubuntu:~$ ls -l /tmp/.mount_Fall-*/opt/qt/6.5.2/gcc_64/lib/libQt6Core.so.6
-rwxr-xr-x 1 root root 6863216 Sep 10 09:18 /tmp/.mount_Fall-llMC6zW/opt/qt/6.5.2/gcc_64/lib/libQt6Core.so.6

I tried to use LD_DEBUG=all, and this is what I see for that lib:

My understanding is that it is simply not found. I do not see errors like missing deps or something else. Moreover, the gui lib is instead found:

Any idea how to investigate further?
