- By default, package-install compiles all the new files, one after the
other, in the current Emacs session. So it tends to emit fewer
warnings than the native compilation (which compiles each file in
a fresh new process) because many more packages have already been
loaded. This same difference can cause the native-compiled files to
be miscompiled (because of a lack of `require`s) while the .elc files
generated during `package-install` work properly.
- Native compilation of a package kicks in when a package that has been
byte-compiled gets loaded in an Emacs session.
So the warnings emitted by native-compilation are always *in addition*
to the warnings that were emitted during `package-install`.
- `.eln` files are specific to a particular Emacs executable, so all the
`.elc` files you use will be *re*compiled to `.eln` every time you
start using a new Emacs executable. For "normal" users this means
every time they upgrade to a new release. For people who track
`master` it can mean "every other day".
