Compiler GCC errors after upgrading to 30.1? Try this.

[summeremacs]

Hi 👋

I upgraded to 30.1 🥳. No issues downloading after upgrading Brew from scratch. Then I launched Emacs and got a ton of libgccjit and gcc warnings which took about 3 minutes to scroll past the Warnings buffer. 😱

My Solution: run Emacs via CLI with emacs --debug-init. Normally I use an Alfred alias to launch it from /opt/homebrew/Cellar. But, for some reason, doing it via CLI with the flag allowed all the compiling to be done. It gave me all the compile messages for a minute or so. After that, launching it via the alias worked like a charm. Not sure why, but it worked for me. I hope this helps someone if they run into this problem. 😀

Welcome to the beautiful world of native compilation. Sounds a bit sarcastic, but it is what it is. Maybe we need to provide a way to disable native compilation after all, or disable it by default 🤷

Let's keep this ticket to collect thoughts and issues.

How do you even get 30.1? brew update doesn't get it for me.

brew update simply updates brew and formulas, but not packages. You are looking for brew upgrade. Although my advice (as written in readme) - uninstall and install - brew abandoned support of custom options and upgrade/reinstall can result in strange state if you want to use options 😅

If you're collecting thoughts, I was happy to see native compilation become the default both in Emacs upstream and Emacs-plus. It makes for a stuttery first few minutes while packages are being compiled, but then a speedier experience after then.

Maybe addressable via note in the README that when first running, it'll be a few minutes or so before it finishes compiling?

I guess I must be using an old version because it was NOT default for me. im getting an error invoking gcc driver message. however emacs seems to be working fine.

You can always verify that by checking the latest commit message in emacs+ formula:

$ cd $(brew --repository)/Library/Taps/d12frosted/homebrew-emacs-plus && git log -1

(adapt it it if you are using fish or another shell)
