With ac237334c7672377721e4d27e8ecd6b09d453568 running Emacs from
Emacs.app is broken.  Steps to reproduce:

git clean -xdf
./autogen.sh
./configure --with-native-compilation
make
make install
Move nextstep/Emacs.app to /Applications
start /Applications/Emacs.app with double-click
=> nothing happens

Don't know if this is helpful.  Alas, I'm not quite on top of what's

It builds fine for me, with native-compilation, on GNU/Linux.

Did you succeed in understanding how the offending commit is related
to the error about file-name-sans-extension?

No, I didn't yet look deeper into this.  I suspect that it has something
to do with one or more of Lars' commits regarding loaddefs.el.  But
that's a wild guess, I don't yet understand what Lars did.

If it works on GNU/Linux that hints at something specific to the macOS
installation procedure, which copies all sorts of files to form an "app
bundle", basically a directory containing everything belonging to an
application.  The easiest explanation would be if the copy misses a file
that isn't copied, or it copies too much.

I'll continue to investigate this tomorrow.

Thanks.

This is probably my fault.  Please see if the following patch helps:

No, I'm afraid that didn't help.

I did the same steps as before, and get an identical result.

I've pushed a fix to master.  It was the change you thought of, Lu, but
there was an additional typo further down in Makefile.in.

BTW, how do I say your name correctly?  What's your first name?  Or do I
say both?

Thanks.  Sorry for the trouble.

Both would be preferable, thanks.

I think what is going on is that while starting we get into
'maybe_defer_native_compilation' where we try to call
`file-name-sans-extension' but this is stil not defined for some reason.
Now why this condition happen has still to be determined.

Perhaps someone should compare this startup sequence with the working
non moved binary?

Thanks
