Install --with-native-comp fails

[briansniffen]

brew install emacs-plus@29 --with-native-comp fails with the error:

Error: invalid option: --with-native-comp

And a Usage message for brew install listing of options that does not include the options from the brewfile.

brew install emacs-plus@29 --with-native-nonsense fails with the error:

Error: invalid option: --with-native-nonsense

And a Usage message for brew install listing of options that does include the options from the brewfile.

Here's a brew config; any ideas where I can look next to debug this?

Thanks for your work on this amazingly useful project!

🤔 Might be some issue with brew. I will upgrade later this day and see what's wrong.

[d12frosted]

Upgraded and it works. Can you try with any other formula that has custom options? Though it's hard to find them, as the homebrew core doesn't allow options. You can create a file called Foo.rb with the following content:

class Foo < Formula
  desc ""
  homepage ""
  url "https://example.com/foo-0.1.tar.gz"
  sha256 "85cc828a96735bdafcf29eb6291ca91bac846579bcef7308536e0c875d6c81d7"

  # depends_on "cmake" => :build

  option "with-ham", "Description of the option"
  option "without-spam", "Another description"

  if build.with? "ham"
    puts ">>> with-ham"
  else
    puts ">>> without-ham"
  end

  def install
    # ENV.deparallelize
    system "./configure", "--disable-debug",
                          "--disable-dependency-tracking",
                          "--disable-silent-rules",
                          "--prefix=#{prefix}"
    # system "cmake", ".", *std_cmake_args
    system "make", "install"
  end

  test do
    system "false"
  end
end

And then install it with brew install --formula Foo.rb --with-ham. It should fail due to 404 error when downloading archive, but at least it should print >>> with ham instead of yelling at you regarding unknown option.

[briansniffen]

That works fine, printing >>> with ham and failing as you predict. brew install emacs-plus@29 --with-native-comp produces a Usage message ending with Error: invalid option: --with-native-comp. And I copied and pasted those strings to be sure. My brew installation is in my homedir for Reasons, and I wonder if that's related. Thanks for your help; I'll keep poking.

[d12frosted]

Not sure if related. As a workaround, clone this repository and install it using brew install --formula Formula/[email protected] --with-native-comp.

[briansniffen]

Thanks for the idea, but same error message. I did some more digging, and have a theory: brew was installing (upgrading) libgccjit, and the option was being passed to it also. Of course, it doesn't support any options. That, in turn, has been failing because of a linker error; see iains/gcc-12-branch#6 — but neither of these is your problem. It looks like a reasonable workaround for installing formulae with options is to install dependencies first without options, then install the formula with options.

I spent an hour looking at Brew code to see where options were being propagated to dependencies, but haven't found it. Thanks for the support & for your work on this tap!

[agzam]

I don't get it, why then emacs-plus@28 ---with-native-comp works (if 29 doesn't)?

[d12frosted]

All I can say, brew position towards options is a twisted one. They keep them, but they advocate for not using them. Since official formulas don't have options, it's not a "well tested feature" that breaks time to time in unexpected ways. Not saying that this is the case, but it might be.

I guess, in that case we can provide better instructions. The same way as we advocate for not using reinstall command ever.

[agzam]

The same way as we advocate for not using reinstall command ever.

Oh, really? So how do you update emacs installed from --HEAD?

[d12frosted]

Oh, really? So how do you update emacs installed from --HEAD?

You can find more some details in the README. In short, options do not properly propagate during reinstall. More or less it was fixed by not using external resources (e.g. patches, icons). Maybe if you are using only --HEAD, then you are fine.

[agzam]

Oh, I guess my question came out wrong. What's the proper/guranteed way of updating emacs-plus@29, so it fetches the latest from master and builds it? brew uninstall and then install again?

[d12frosted]

@agzam as far as I remember, reinstall handles fetching of the latest master. But there are troubles if you are using any options, that's why I advise to use combination of uninstall and install. That allows you to upgrade and properly propagate all options.

P.S. I feel like I need to taste this again, it's possible that they fixed the old behaviour.

[agzam]

Yeah, because I remember using reinstall and haven't noticed any problems, I dunno. Maybe I simply wasn't paying attention? My usual flags are --with-native-comp --with-xwidgets --with-modern-papirus-icon --verbose. But thank you for the heads up. Next time I'll keep a closer eye.

Got the same issue. Have you made any progress @briansniffen ?

[briansniffen]

Sure. Downgrade xcode-cli and then install libgccjit in a separate brew command. -- Brian SniffenOn Oct 5, 2022, at 11:22 AM, nik ***@***.***> wrote: Got the same issue.

Thanks for your answer.
I installed libgccjit without options in a seperate brew command as described in your earlier comment.
That didn't do the trick, since following up with installing emacs with options fails with the same error.

I didn't downgrade xcode-cli, though, as I don't really know what exactly was mean't by that.

If it’s failing with an error about ld when installing libgccjit, download XCode command line tools from before Xcode 14 from developer.Apple.com. If it’s failing with an error about option processing when installing Emacs, you have not installed the proper gccjit or other dependencies. You might try installing Emacs without options to get the dependencies right, check that you have the right libgccjit (12?) and then remove emacs and install it with the native-comp option. -- Brian SniffenOn Oct 8, 2022, at 2:49 AM, nik ***@***.***> wrote: Thanks for your answer @briansniffen .
