Install with --with-native-compilation option causes scrolling stutters and produces an error on exit

Closed this issue ยท 7 comments

What you were trying to do

Install emacs-mac with the --with-native-compilation option on both an Intel and M1 MacBook running macOS 13.4.1.

What happened

$ brew install emacs-mac --with-modules --with-native-compilation --with-emacs-big-sur-icon

Everything appears to install okay. At first doom emacs was giving me errors when I tried to run any doom command like doom sync. I fixed that by reinstalling gcc and libgccjit though.

brew reinstall gcc libgccjit

Now emacs-mac installs without error, and doom sync, doom upgrade, and doom doctor all work without errors.

So far so good! But here's where I run into two problems.

Problem 1

When scrolling through a file in emacs, there are stutters every 0.5-1.0 seconds. This is when holding the j/k keys to move the cursor up and down the file.

Problem 2

When exiting emacs C-x C-c, immediately upon exiting, macOS throws up an error report. Sometimes I get 1 report, sometimes I get 2, and sometimes I get 3, all when quitting the application a single time.

Thread 1 Crashed:: org.gnu.Emacs.lisp-main

Solution

The only thing that fixes both of the above problems, at least that I've been able to determine, is not using the --with-native-compilation when building emacs-mac.

$ brew install emacs-mac --with-modules --with-emacs-big-sur-icon

When I build without native-compilation, scrolling works without issue, and I get no errors when exiting the app.

It's worth noting that I was able to get rid of the errors when exiting the app by creating an early-init.el file that contained the following (when I was running emacs with the --with-native-compilation option):

(setenv "LIBRARY_PATH"
	(string-join
	 '("/opt/homebrew/Cellar/gcc/13.1.0"
	   "/opt/homebrew/opt/libgccjit/lib/gcc/current"
	   "opt/homebrew/opt/gcc/lib/gcc/current/gcc/aarch64-apple-darwin22/13")
	 ":"))

Even though this fixed my error when exiting the application, I still ended up with stuttering when scrolling through files.

Output of brew doctor

$ brew doctor
Your system is ready to brew.

While the stuttering's happening, do you have a buffer called *Async-native-compile-log*? (SPC-b-B to switch to it) Emacs used significant CPU for me until that buffer's process finished after a few minutes.

Thank you for the reply. That looks like it solves my first problem! ๐Ÿ‘

I wasn't giving emacs enough time, and it was still compiling for about 4-5 minutes the first time I open the app (after install Doom emacs).

Cool! I'm also here from Doom - found your issue while looking through doom doctor output.

Can confirm I've also got your second issue. Though adding the LIBRARY_PATH value at the end of ~/.config/emacs/early-init.el doesn't prevent the crashes on exit for me (adding it earlier tells me that string-join's definition is void). I've confirmed I have all 3 directories.

Looks like the last path in LIBRARY_PATH is missing a leading /.

The crashes only happen for me after opening files (elisp config), not if I exit from the splash screen. They happen whether loading the last session in Doom or opening files directly.

Are you on an ARM or Intel Mac? The LIBRARY_PATH I posted above is for an ARM Mac. Homebrew uses a different base path for Intel machines, so if you're on Intel I think that needs to be changed to /usr/local.

@kris-anderson you still have a missing slash above:

	   "opt/homebrew/opt/gcc/lib/gcc/current/gcc/aarch64-apple-darwin22/13")

Thank you for catching that!

Just to update my post, this seems to have been fixed in version 29 of Emacs. I no longer get error reports (my second issue) when exiting Emacs! :)

Sorry for the delayed reply, I'm on an ARM Mac as well. Glad that it's fixed, my error reports are gone too! ๐ŸŽ‰
