Issues building Emacs.app for Mac OS from source with native
compilation

Hello! I've been struggling with this issue for several days now and
wondered if any Mac OS Emacs users have successfully overcome it. I
created a thread on the [Emacs
StackExchange](https://emacs.stackexchange.com/q/74239/38373)
describing the issue and my attempts at solutions in detail, but the
gist is:

1. I'm building Emacs from source on Mac OS, 12.4 w/ M1.

2. I'm configuring Emacs with native compilation.

```
./configure --with-native-compilation \
            --with-ns \
            --disable-silent-rules
```

3. The build succeeds, `src/emacs` runs like a charm and I `make
install`.

4. My nextstep/Emacs.app runs, but emits a ton of `libgccjit.so:
error: error invoking gcc driver` errors to the Messages buffer.

I suspect the Emacs.app package has some misconfigured paths that are
unable to find my `libgccjit` library, which I've installed via
homebrew. I've tried experimenting with [exec-path-from-
shell](https://github.com/purcell/exec-path-from-shell) to ensure
Emacs is aware of my shell paths, but to no avail.

In the meantime, I've been able to use `emacs` and `emacsclient` from
the CLI with no issues to speak of. The only problems arise when I
interact with the Emacs.app application. Anyone have an idea as to
what's going on here?

you could try with this script. Works for me on macos 12.6.

I would use the emacs-mac-app from MacPorts if I were you. Simple and
effective.

This looks very promising, thank you! I’ll see what differences the
author includes.

    brew tap d12frosted/emacs-plus
    brew install emacs-plus@28 --with-native-comp

Yeah this is what I use at work but I’m trying to build from source so
I can learn more about the emacs internals.

I followed this path: [https://gist.github.com/mikroskeem/0a5c909c1880

No problems so far
