Bug 831508 – media-libs/aften-0.0.8-r2 fails with undefined reference to `apply_simd_restrictions'

• Product: Gentoo Linux
• Status: UNCONFIRMED ---

[Description korte 2022-01-19 21:36:30 UTC]

When emerging aften I get the error [2]

I found:
* <https://trac.macports.org/ticket/62196>
* <https://github.com/Homebrew/linuxbrew-core/blob/master/Formula/aften.rb>

The first link states: "aften @0.0.8: error: implicit declaration of function 'apply_simd_restrictions' is invalid in C99"  
The second link has a patch [1] at the end. With that patch aften gets compiled. I have no testcase yet.

I converted a soundfile from simutrans with aften and mplayer was able to play it.
