[nsipplswezey]

Please note we will close your issue without comment if you delete, do not read or do not fill out the issue checklist below and provide ALL the requested information. If you repeatedly fail to use the issue template, we will block you from ever submitting issues to Homebrew again.

Please always follow these steps:

• Confirmed this is a problem with brew installing one, specific Homebrew/homebrew-core formula (not cask or tap) and not every time you run brew? If it's a general brew problem please file this issue at https://github.com/Homebrew/brew/issues/new. If it's a brew cask problem please file this issue at https://github.com/caskroom/homebrew-cask/issues/new. If it's a tap (e.g. Homebrew/homebrew-php) problem please file this issue at the tap.
• Ran brew update and retried your prior step?
• Ran brew doctor, fixed all issues and retried your prior step?
• Ran brew gist-logs <formula> (where <formula> is the name of the formula that failed) and included the output link?
• If brew gist-logs didn't work: ran brew config and brew doctor and included their output with your issue?

To help us debug your issue please explain:

• What you were trying to do (and why)

Looked into #20546 #20104 and #20317 and though they seemed similar –maybe even related– none of those involved this specific error.

• What you expected to happen

Expected ffmpeg to install without problem.
brew install ffmpeg with no options installs without problem.
brew install ffmpeg --with-libass --with-fontconfig installs without issue on my laptop running macOS Sierra 10.12.6 Xcode 9.1.

• Step-by-step reproduction instructions (by running brew install commands)

Uninstall ffmpeg if it's already intalled. Run brew install ffmpeg --with-libass --with-fontconfig

Can you please try adding --build-bottle and see whether it makes any difference?

[nsipplswezey]

Same outcome. Output and gist here.

@nsipplswezey I think you may have something strange set in your environment. aarch64 is ARM not Intel but that's what configure shows being used.

[nsipplswezey]

Nice catch. Thanks for the response. You might be on to something.
On my laptop running Sierra ARCH is x86. Install works as expected.

Seems like it's worth getting to the bottom of this.

Could you point me to where brew generates the output in the gists-logs 01.configure file?
Or any hunches on where you might imagine the strange set to aarch64 might be in my environment?

[ilovezfs]

Please try this:

export HOMEBREW_ENV_FILTERING=1
brew install ffmpeg --with-libass --with-fontconfig

[nsipplswezey]

That did it. I'll keep that in my back pocket if I run into future issues. Took a look at Homebrew/brew#932 for reference.

Assuming that arch environment variable is the root of this, I'm still wondering what the potential candidate list is for where this variable is coming from.

A cursory check

Macintosh-7:~ nsipplswezey$ arch
i386
Macintosh-7:~ nsipplswezey$ uname -p
i386
Macintosh-7:~ nsipplswezey$ uname -m
x86_64

All references to architecture in the system_profiler dump seem to reference x86_64, and no occurances of aarch64

Also for reference, here's the gist-logs output after the successful install after turning on env filtering with export HOMEBREW_ENV_FILTERING=1
https://gist.github.com/nsipplswezey/4fc4da65210ab9852b00ebe379ed5499

Thanks again for your help, and for homebrew. Any other hunches on where this might be originating appreciated.

[ilovezfs]

You need to check the output of the env command.

It's probably something in your ~/.bash_profile file.

[nsipplswezey]

Thanks for the reply. Checked my ~/.bashrc + ~/.bash_profile and I actually have an explicit `export ARCHFLAGS="-arch x86_64"` but you're right that my `env` command has a weird `arch=arm64` in it ``` arch=arm64 ARCHFLAGS=-arch x86_64 NATIVE_ARCH_ACTUAL=x86_64 ``` Know any neat tricks for backing into seeing where a specific `env` variables gets set, or to watch `env` be built? This is debugging beyond homebrew, but thought I'd ask since there's a context for the question. Thanks again for all your help. And for keeping homebrew possible.

You're welcome!

You can try running

bash -ilx

[nsipplswezey]

Super handy. Thanks!
