You probably have a problem with libposproc and CPU_CFLAGS:
| Code: |

Is an unconfirmed bug
However, HeXiLeD presented a workaround : https://forums.gentoo.org/viewtopic-t-1079186-start-0.html
Also, you can double check if your flags are right. |

i successfully emerged this ffmpeg version in early jan & feb. some later update/change is making emerge failed now.
HeXiLeD has ffmpeg-3.4.2, while mine in ffmepg-3.3.6. guess i'll have to live with this bug for the near future.

Are my FLAGS right?
| Code: | $ cat /etc/portage/make.conf | grep FLAGS
CFLAGS="-march=core2 -fomit-frame-pointer -ftree-vectorize --param l1-cache-line-size=64 --param l1-cache-size=32 --param l2-cache-size=2048"
CXXFLAGS="${CFLAGS}"
FFLAGS="${CFLAGS}"
FCFLAGS="${FFLAGS}"
CPU_FLAGS_X86="mmx mmxext sse sse2 sse3 ssse3" |

Thinking of FLAGS and what might have changed, I added these flags back again that I had removed some months ago.
| Code: | CFLAGS="${CFLAGS} -O2 -pipe"
CPU_FLAGS_X86="${CPU_FLAGS_X86} cx16 sahf fxsr" |
And now ffmpeg compiles successfully.
I am a bit surprised, as I thought default included -O2 and -pipe.
Also, I had removed cx16, sahf, and fxsr as cpuid2flags didn't list them. They are listed by gcc query and lscpu.

| The default does include -O2 -pipe, but the flags you posted with your Useless Use Of Cat do not explicitly inherit the defaults, and CFLAGS do not implicitly inherit the defaults. Since they were not inherited and not included explicitly, they were absent and ffmpeg was built with the default optimization level of -O0. Correct programs should still build at that level, but it's not commonly tested. |

so how or what should i do instead?

josephg ... Hu means that the portage doesn't automatically collate the 'default' and whatever you've defined. In fact the opposite, it's only the absence of CFLAGS in make.conf that would then allow the default to be used. Consider the following example:
| Code: | % export myvar="foo bar"
% echo $myvar
foo bar
% myvar="baz" ; echo $myvar
baz
% export myvar="foo bar"
% myvar="$myvar baz" ; echo $myvar
foo bar baz |
You see 'myvar' isn't collated when redefined, and so doesn't retain the initial value. So, you could use CFLAGS="$CFLAGS -flag -flag" ... but I see no point to it, you should just define the flags you want.

Hu is not saying you *should* inherit, only that these are not inherited without explict inclusion (ie, CFLAGS="$CFLAGS").

You used a 'cat' when grep is perfectly capable of accepting input in the form of a file, eg:
| Code: | % grep CFLAGS /etc/portage/make.conf
CFLAGS="-O2 -march=native -pipe"
CXXFLAGS="$CFLAGS" |
... look, no cat :)
best ... khay |
