Yes from PATH with emacs which is a symlink in /usr/local/bin pointing
to /usr/local/sbin/emacs-28.0.50/emacs-28.0.50.
And yes emacs starts fine like this. And if I start it from
/usr/local/sbin/emacs-28.0.50/emacs-28.0.50 with ./emacs it fails to
start with always the same error:
emacs:
/usr/local/sbin/emacs-28.0.50/../native-lisp/28.0.50-2f134e58/preloaded/window-0d1b8b93-581f9fcd.eln:
cannot open shared object file: No such file or directory
I also don't understand why emacs start from /usr/local/bin/emacs (the
symlink) but not directly from the true directory
/usr/local/sbin/emacs-28.0.50/emacs-28.0.50 with ./emacs.

No.

Yes it starts.
But then fails with dired-async with and without the native-lisp/ symlink.

Yes.

As said above it starts fine from /usr/local/bin but fails from
/usr/local/sbin/emacs-28.0.50/emacs-28.0.50 and running ./emacs.

No problems.
