Native comp on Emacs 29 does not seem to work

[jmckitrick]

I think I found a solution. I'll post details when I'm sure....

[jmckitrick]

Problem solved! I needed to run brew edit and remove the line with -march=native and everything worked fine after that.

[daviderestivo]

Try to uninstall emacs-head@28 and libgccjit and install emacs-head@29 and libgccjit once again.

[jmckitrick]

Same exact result. The build succeeds, but starting emacs produces the same error messages.

[daviderestivo]

Just to be sure, have you tried to:

$ brew uninstall gcc libgccjit
$ brew install gcc libgccjit

?

[jmckitrick]

Yep, I just tried the whole process again, with the same result. Very frustrating. Could it be a classpath or lib path issue?

Do you have something in early-init.el? or did you set LIBRARY_PATH manually? Can you give me the output of env from a shell?

[jmckitrick]

No, nothing special. Emacs can find ripgrep, java, clojure, scala, etc.

Please share there output of env and the content of early-init.el :)

[jmckitrick]

Nothing in early-init.el

[jmckitrick]

Also, exec-path:

exec-path is a variable defined in ‘C source code’.

Its value is
("/usr/bin" "/bin" "/usr/sbin" "/sbin" "/usr/local/Cellar/emacs-head@29/29.0.50_1/libexec/emacs/29.0.50/x86_64-apple-darwin20.6.0")

[jmckitrick]

It turns out there are instructions in a troubleshooting README in emacs source for adding an early-init.el with correct library paths for macos. That seemed to do the trick.

Final question: will native comp work with the M1 chip?

Could you please share a bit more details?

As far as I know yes but I didn't test myself.

[jmckitrick]

I followed these directions and it almost worked. One caveat: I needed this line as well

(eval-when-compile (require 'subr-x))

There might be a better way, but at least it's working now.

[jmckitrick]

Now I'm trying on M1, and even though the entire project builds and runs as normal (regular emacs head) trying to add native compilation fails early in the process. I have a feeling this is a simple config issue, but I'm not sure how to tackle it for arm64.

[jmckitrick]

I thought maybe it was a 'no correct' setting in my zsh config, but even when I removed that, I got the error.

I think the problem is that the compiler is not found. Do you have the "Command Line Tools" installed under /Library/Developer/CommandLineTools/?

[jmckitrick]

I thought you might be right, but I checked, and the folder is there with all the tools. I've also asked on the emacs help forum.

A user suggested I manually set CFLAGS or remove -march=native.

I've worked with Linux projects and autoconf a bit in the distant past, but I have not worked with brew formulae. How might I do this?

[daviderestivo]

Fixed in #139. Please lemme know if it works for you.
