[Message part 1 (text/plain, inline)]

I just update the gcc and the libgccjit through `brew` tonight and find building the emacs from source has issue.

after `./autogen.sh`, I ran the `./configure --with-native-compilation` (for simplifying) and got the error message that

```
checking for gcc_jit_context_acquire in -lgccjit... no
configure: error: ELisp native compiler was requested, but libgccjit was not found.
Please try installing libgccjit or a similar package.
If you are sure you want Emacs be compiled without ELisp native compiler,pass the --without-native-compilation option to configure.

```

I add `echo $MAC_CFLAGS` and `echo $MAC_LIBS` after line 4269 in `configure.ac` and I figure out it gives me the right including path of libgccjit 12.

```
-I/usr/local/Cellar/libgccjit/12.1.0/include
-L/usr/local/Cellar/libgccjit/12.1.0/lib/gcc/current /usr/local/Cellar/libgccjit/12.1.0/lib/gcc/12
```

my environment:

macOS 12.5
intel CPU

Thanks.

Yes, I think we have to put a fix for this on the release branch, but as
Eli says, it must be safe.  (And this has been a surprisingly difficult
thing to get right -- it seems so simple, but the differences between
brew/Macports/versions of the basic utilities have led to numerous
breakages here.)

The 'x' is kind of confusing here because MAC_LIBS can't be empty at
this point.

> Is 'dirname' guaranteed to be available?

Yes (POSIX).  And it was used already.

This x prefix is not about emptyness, but preventing a pre-POSIX test
utility from being confused by the leading dash.

Any objections to a fix in master?

Not on master, no.  My problem is what to do with the release branch.
If you think the solution based on Ruby is fine and safe, please
install that on the release branch (and it will be soon merged to
master).

Otherwise, which of the other solutions proposed here and in related
discussions do you recommend that is safe enough for the release
branch?

Thanks.

Thanks!  I've done that on emacs-28.

And I guess that fixed this bug?  So I'm closing this bug report now.

(If I misunderstood, please respond to the debbugs address and we'll
reopen.)
