You will find the code in async-start function in async.el https://github.com/jwiegley/emacs-async/blob/master/async.el#L296 >> >> thierry IPadS340:/usr/local/sbin/emacs-28.0.50$ ./emacs-28.0.50 >> >> emacs: /usr/local/sbin/emacs-28.0.50/../native-lisp/28.0.50-40158ec0/window-0d1b8b93-738411b0.eln: cannot open shared object file: No such file or directory >> >> thierry IPadS340:/usr/local/sbin/emacs-28.0.50$ ./emacs >> >> emacs: /usr/local/sbin/emacs-28.0.50/../native-lisp/28.0.50-40158ec0/window-0d1b8b93-738411b0.eln: cannot open shared object file: No such file or directory >> >> Yes I sent this because I thought it was a straight forward way to show >> the problem, however the strange thing was emacs was starting with no >> apparent errors from its symlink in /usr/local/bin/ > > Are these messages emitted by the "emacs --batch" invocation done by > dired-async-mode, No, unfortunately it is really hard to get error messages from async.el. These message came from calling ./emacs or ./emacs-28.0.50 from /usr/local/sbin/emacs-28.0.50/.
