thanks.

thanks; I haven't really looked into that but may if time permits.  But it's
hard enough just keeping up with one system.

Thanks, my error in not going back and re-reading.

I found a centos x86_64 version and unpacked it:

$ ls -lt /compat/linux/usr/lib64 | head
total 27564
-rwxr-xr-x  1 root  wheel    16176 Feb  9 19:32 libulockmgr.so.1.0.1
lrwxrwxrwx  1 root  wheel       20 Feb  9 19:32 libulockmgr.so.1 -> libulockmgr.so.1.0.1
-rwxr-xr-x  1 root  wheel   269368 Feb  9 19:32 libfuse.so.2.9.7
lrwxrwxrwx  1 root  wheel       16 Feb  9 19:32 libfuse.so.2 -> libfuse.so.2.9.7

But the .AppImage still chokes with an error loading the library:

$ ./PrusaSlicer-2.3.0+linux-x64-202101111322.AppImage
dlopen(): error loading libfuse.so.2

Do I need to do something other than place the lib in the right place?

Is there a way to run /compat/linux/usr/bin/ldd to figure out what it is
really looking for?  I get the same error whether the symlink for libfuse.so.2
is present or not.  If I try to run the linux ldd I get:

$ /compat/linux/usr/bin/ldd PrusaSlicer-2.3.0+linux-x64-202101111322.AppImage
bash: /compat/linux/usr/bin/ldd: /usr/bin/bash: bad interpreter: No such file or directory

There is no /usr/bin/bash (it's in /usr/local/bin/bash), but there is a
/compat/linux/usr/bin/bash.
