homebrew-emacs-plus: Could not install Emacs 28

Sorry for the delay, some stuff came up and I couldn’t devote any time to this.

Sure, no worries. Plus I understand that it requires uninstalling Emacs and messing around with your environment. That’s why I really advice you to use build script from the repository as it allows you to test installation without uninstalling Emacs 😸 Basically it just creates a formula called emacs-plus-local, which can be built alongside with emacs-plus. It fails during linking obviously, but we are testing how it builds.

Also you can create a script like this:

#!/usr/bin/env bash

export PATH=YOUR_PATH

./build 28 --verbose [OPTIONS]

That will help you with testing in specific PATH setup.

error message is emitted either - do you have any idea? It doesn’t look like what tar (either gnu-tar or macOS tar) emits when you pass it a bad flag:

That’s interesting observation. I have no ideas right now, but might be a good lead. Will take a look later.

I see. Thanks for testing. Not sure why it picks incorrect tar. Will dig into it later.

Oh ok, I just tried on your patch with gnu-tar on my PATH but no coreutils in PATH and it still failed with the previous ls error 😦

So I’ve prepared a (possible) fix - #468. I would be grateful if you test it locally after you revert you changes to PATH. Basically, you can do the following (assuming jq is installed):

1. cd $(brew tap-info --json d12frosted/emacs-plus | jq -r '.[0].path') && git switch fix/stdenv-build
2. brew install emacs-plus@28 [OPTIONS].

Thank you in advance 😃

next build failure involves Apple gzip, brew installing that seems to resolve it, though, and the build succeeds now! 🎉

Hey,

Looks like this one has the same root cause as #465. In this case it’s related to ls. Since ls is not used by formula directly, I am not sure how to properly fix that, but you should be able to workaround it in the same way you did it with #465. Just install coreutils and prepend them to the PATH.

Meanwhile will think about better solution.
