[gentoo-user] Cannot reinstall ffmpeg since new cpu flags

[gentoo-user] Cannot reinstall ffmpeg since new cpu flags

[Matthias Hanft]

Hi,

I have installed the new CPU_FLAGS_X86, as "cpuinfo2cpuflags-x86"
told me: CPU_FLAGS_X86="mmx mmxext sse sse2 sse3"

When I did "emerge -NDuv @world" afterwards, there were some re-installs.
Everything was fine, except ffmpeg. emerge displays:

[ebuild   R    ] media-video/ffmpeg-1.2.6-r1  USE="bzip2 encode examples fontconfig gnutls hardcoded-tables iconv libcaca mp3 network truetype vorbis x264 xvid zlib -X -aac -aacplus -alsa (-altivec)

and running emerge, after many lines, I get

make: *** Waiting for unfinished jobs....

Google can't find this special error message (yet?), so I believe I'm
the only one getting that error (and, hence, didn't want to file a bug
report instantly). Perhaps I set some weird use flags?

(No graphics installed on that machine, it's just a server which uses
command-line ffmpeg-converting, mainly sound files, not even videos.)

Thanks,

"cpuinfo2cpuflags-x86" isn't telling to turn on all these flags
unconditionally but only those that are included in "USE" in
make.conf.

What's the output of the command lines shown below on your system?

grep -Es 'ffmpeg|CPU' /etc/portage/*

equery -q u media-video/ffmpeg|grep cpu

You failed to include the real error message in your email. Look
further up in the log for a line containing "error:".

Ah, I actually missed that:

Kernel 3.17.7, BTW. Last compilation is a long time ago (maybe 3.12 or so)

Where did you get that silly idea? cpuinfo2cpuflags-x86 tells you
exactly what to put in make.conf based on your host CPU.

The piece of source code at that point:

__asm__ volatile(\
    "cmpl  %0, %3       \n\t"\

    : "+&r" (x), "+&r" (a), "+r" (c)\
    : "r" (y), "r" (b), "r" (d)\
);
#endif

and the emerge messages:

Ok. It tells me what _could_ be put in the new variable in make.conf. But
make.conf existed before this new variable. And what flags existed in it -
it's a separate question. If one wants to keep 'status quo', he should only
duplicate those cpu flags whis were in USE to this new variable. If some
cpu flag wasn't in USE, he shouldn't add it to the new variable.

Ah uh...

/etc/portage/package.use:# this is necessary for ffmpeg update (see gentoo-bug 290741)
/etc/portage/package.use:media-video/ffmpeg -pic

Seems that I didn't USE "mmx" before, and, therefore, had to disable
"pic" manually (because of the bug mentioned). Now "mmx" came into
CPU_FLAGS, and obviously "mmx" and "pic" have to be enabled or disabled
simultaneously.

Thanks - this was a long-forgotten configuration...
