Bug 283968 – media-video/ffmpeg: Unknown CPU "athlon64-sse3" (k8-sse3, opteron-sse3)

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Dennis Schridde 2009-09-07 09:57:13 UTC]

The configure process of media-video/ffmpeg reports: Unknown CPU "athlon64-sse3", because -march is set to that value on this machine.
The logic in the ebuild should replace athlon64-sse3 (and possibly also k8-sse3 and opteron-sse3) with just athlon64 (k8, opteron), so that ffmpeg's configure properly detects the correct CPU.

Reproducible: Always

same goes for -march "native"
--> Unknown CPU "native"

With ffmpeg-0.5_p20373 and -march=native works here fine

With "k8-sse3" "opteron-sse3" works not correct

Fixed in 0.5_p20601-r1 and 9999-r1, thanks for reporting.

In ffmpeg-0.5_p22846 and newer configure have:

*-sse3)             echo -xarch=sse3                 ;;

and works fine with -march=k8-sse3

And:

...
C compiler                x86_64-pc-linux-gnu-gcc
ARCH                      x86 (k8-sse3)
big-endian                no
runtime cpu detection     no
