Native compilation happens automatically when you > _load_ a .elc file, not when you compile it. The info manual I was looking at (info "(elisp) Native-Compilation Functions") has this text "Native-Compilation is implemented as a side effect of byte-compilation" In any case maybe I should file a bug? because this the behaviour I reported doesn't meet the expectations. In a fresh emacs -Q: the following 3 forms all load a fib.elc file from the current directory (say "/dev/shm") without producing an eln file. ("doesn't work") (byte-compile-file "fib.el" t) ; doesn't work (load-file "fib.elc") ; doesn't work (load "/dev/shm/fib.elc" nil nil t) ; doesn't work The only form which works seems to be when load is called with a full pathname after omitting the ".el" or ".elc" suffix provided there is an elc at that location. i.e. (load "/dev/shm/fib") only this form produces an eln file in the user's eln-cache directory.
