libavdevice build error (Mac M1 Silicon) about homebrew-ffmpeg

[slhck]

I can reproduce this on 13.5.2 on a M1 machine.

@loshlee Thank you for the information. I assume you are installing the standard Homebrew ffmpeg formula, but I would like to fix this one.

[freultwah]

This is apparently an Xcode issue introduced in Xcode 15 beta 3: https://developer.apple.com/forums/thread/733317. I had the same issue with ld: building exports trie: duplicate symbol '_av_ac3_parse_header' and reverting to Xcode Command Line Tools 15b2 made stuff work.

[fxcoudert]

This is a workaround, but Apple will need to fix their linker. Has the issue been reported to Apple? If so, what is the FB number?

[slhck]

Please test again, I could confirm it working now with the fix from @retokromer

[Moulick]

works now

[retokromer]

@loshlee Thank you for reporting! I cannot test now on macOS 13.6, but will do it in approximately one week time.

[slhck]

It also fails without any options, so these aren't causing the problem.

Someone mentions on a forum that this Formula gives the same error: https://github.com/apple/homebrew-apple/blob/main/Formula/game-porting-toolkit.rb — this does not have a lot in common with our formula.

[retokromer]

@loshlee Could you possibly test is the fix by @slhck solves your issue?

[slhck]

@retokromer The PR does not fix this, it just fixed a related issue attempting to run the command from @loshlee. So I'm reopening now...

[retokromer]

Oh, sorry @slhck, for the noise.

[retokromer]

It also fails without any options, so these aren't causing the problem.

It seems to be related to clang 15.

Same here while trying install ffmpeg with "--enable-libfdk-aac" .

Let me know if you want me to run any commands or collect diagnostics to assist with troubleshooting this issue.

[retokromer]

It also fails without any options, so these aren't causing the problem.

The relevant lines are always the same:

[slhck]

Hmm. I have Xcode Version 15.0 (15A240d) and have this issue.

[freultwah]

It's apparently broken from 15b3 onwards, still not fixed even in the release.

[retokromer]

I don’t have Xcode on this machine and CLT (15.0.0.0.1.1694021235) also is broken.

[petersteneteg]

related PR from spack with a potential fix spack/spack#40187

[loshlee]

My workaround has been to use "brew uninstall --ignore-dependencies ffmpeg", then use "brew install ffmpeg".

[loshlee]

Thanks, everyone.

[sourcecodemage]

What is the work around, as in , what commands do I need to run ? Should I run brew update && brew upgrade && brew install homebrew-ffmpeg/ffmpeg/ffmpeg --with-fdk-aac ?

Update: That worked for me. Background - I had a different ffmpeg installed at the beginning. I uninstalled it and trying installed homebrew-ffmpeg with with-fdk-aac support so that I could get another application - "m4b-tools" - to install. That failed with the libavdevice error. Running the brew commands I listed above was successful for me.

[loshlee]

Hard to be sure without more information. If your last successful initial installation included "--with-fdk-aac", and you haven't used other offhand attempts at workarounds and/or installation, I think this might suffice:

brew reinstall homebrew-ffmpeg/ffmpeg/ffmpeg

If you don't see "--with-fdk-aac" in the output of that command, then installation with that option may require other steps. Anyway, that's what worked for me (I had previously also used "--HEAD").

[retokromer]

There is no workaround: just use the regular installation. And if you get an error, please open a new issue, providing all the requested information.
