Description Norman Rieß 2021-12-28 10:26:36 UTC
media-video/ffmpeg-4.4.1-r1 fails to build on arm64 with error message:

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

COMMON_FLAGS without "-march=native" leads to a successfull build.

Please do include the build.log of it failing too. I'm pretty sure i've built this on arm64 with -march=native which is interesting.

Build log for media-video/ffmpeg-4.4.1-r2 with no march/mtune set

On my KVM hosted gentoo on armv8-a machine (Apple M1) this also fails without any -march or -mtune

Could you share ffbuild/config.log too?

ffbuild/config.log

please be aware that the compile was run with
CFLAGS="-O2 -pipe" emerge --ignore-default-opts media-video/ffmpeg

Comment 9 Red 2022-11-16 23:29:27 UTC
I am also hitting this issue. With both 4.4.2 and 4.4.3. I am surprised 4.4.2 is stabilized regardless of this bug. 

I have been looking for a definition on what the build system uses --cpu for, but can't seem to find it documented anywhere. Does it do anything -march=native and --disable-runtime-cpudetect doesn't? Does it select the cpu for the disabled runtime checks?

Assuming it does something, I still vote having this configure flag(s) not added on arm64 for the time being. Not that I don't want the deeper issue to be resolved ofc
Comment 10 Red 2022-11-16 23:41:29 UTC
I just saw the forum post you sent sam_, missed that earlier. If the issue here is really the ffmpeg build system not knowing my cpu, this error message is fairly misleading.

I also just noticed that I'm the first person to hit this in half a year. Attaching my emerge --info:

(CPU is a snapdragon 662)
