Native compile problems on M1 Mac

Native compile problems on M1 Mac

I am trying to get native compilation to work on an M1 Mac — macOS 13 (Ventura).

I have done `brew install gcc` and `brew install libgccjit` but I hit the same error in different forms in different places.

Originally, with the native compile test program, when I ran it, I got

./tut01-hello-world
ld: library not found for -lemutls_w
libgccjit.so: error: error invoking gcc driver
NULL result%

I reinstalled gcc and libgccjit and now I get:

 % ./tut01-hello-world
ld: warning: -undefined dynamic_lookup may not work with chained fixups
hello world
% echo $?
0

And I can now do `make configure="--with-native-compilation” install` and the configure, compile, and install work.  I move the new Emacs.app into /Applications and double click it and I get this in *Warnings*

⛔ Warning (initialization): An error occurred while loading ‘/Users/pedz/.config/emacs/early-init.el’:

So, I am back a problem with the native executable can not find libemutls_w

I went as far as uninstalling gcc and libgccjit, reboot, and tried again but get the same result.

I am assuming that I don’t have something set up right.  Maybe something with Xcode …. I am hoping someone here has seen this before.

Thank you for your time,
Perry

I assume native compilation works when you start Emacs from a shell?  I 
mean something like

	cd emacs/src
	./emacs

If native compilation works when started from the shell, your problem 
might be that some environment variables that are set in the shell are 
not set when you start Emacs by opening the application bundle 
Emacs.app.  This is normal because there is no shell involved in opening 
a bundle.

You can see the environment variables in Emacs in the variable 
process-environment.
