Hi,

I'm having trouble emerging ffmpeg.

I tried getting rid of it as a dependancy, but what I tried (putting -ffmpeg in the global USE variable) did not prevent it from being pulled in by plasma-meta

Is there a way to either remove the dependency, or prevent the error?

Thank you

Are you compiling natively on an ARM system?
Or using a cross-compiler?
Or a cross build environment with qemu?

Hi shadowless,

I'm compiling natively.

Post by **NeddySeagoon** » Mon Mar 11, 2024 1:14 pm

Progman3K,

What does

Code: Select all

emerge --info

sudo say?
and resolve-march-native ?
You need at least version 3 on arm64.

Ahh ...

Code: Select all

--optflags=-march=native -O2 -pipe

I've had problems with -march=native on arm64 in the past. I'll try

Code: Select all

emerge =media-video/ffmpeg-6.0.1-r3 --buildpkgonly

== edit ==

To target a Pi4 while building on a hawk, I use

Code: Select all

--optflags=-mcpu=cortex-a72+crc -mtune=cortex-a72 -ftree-vectorize -O2 -pipe -fomit-frame-pointer

and that gets past the .configure step ... and builds.

== edit ==

On a Pi5. it fails as you report, using -march=native.

Code: Select all

--cpu=host not supported with compiler aarch64-unknown-linux-gnu-gcc

That's a bug, please file a bug at [bug=]bugs.gentoo.org[/bug], if its a new finding.
