Hi, sorry for my obscure message. The fact is that I’m trying to compile Aquamacs (aquamacs.org) from its git repository. Latest version is 3.6  (GNU emacs 23.50.1). The application can be downloaded from the aquamacs site, but I want to compile it on my new Mac as a check of its capabilities as a whole. It stops with the warning "configure: error: Emacs does not support 'arm-apple-darwin21.3.0' systems. If you think it should, please send a report to bug-gnu-emacs@gnu.org. Check 'etc/MACHINES' for recognized configuration names." Now I do not know whether is responsibility the developer of aquamacs, and I issued this bug# to try to understand. I tend to believe that it’s responsibility of aquamacs… Best wishes, E.O. ______________________________ Prof. Enrico Onofri INFN, gruppo di Parma C/O Dip. di Mat.
