emerging mpv fails[solved]

[Adel Ahmed]

this is afreshly installed gentoo, ffmpeg is already emerged but it seems it's not being detected during compiling ffmpeg

error:

[bstaletic]

What is the output of qlist ffmpeg | grep libavcodec?
Your emerge output is missing the [code] tag.

[Adel Ahmed]

I've corrected the missing code tag, thanks

libavcodec is provided by ffmpeg itself? https://www.portagefilelist.de/index.php?ps=libavcodec*&p=package&id=c352ee532651af9e1a07aaeb7a3be5de#panchor

[Adel Ahmed]

no it literally ends in a dot, and i do not think the content of libavcodec is correct:

[bstaletic]

Rebuild ffmpeg. You're on a i686 system with ABI_X86=32. It seems like binhosts do not serve that.

For the record, the pkgconfig file should look sometihng like this:

[Adel Ahmed]

I have re emerged m that seems to ave fixed the blank libavcodec.pc:

[bstaletic]

That's still an incomplete pkgconfig file. It is lacking all version information, just like your shared object.
At this point, we can be sure that something is causing ffmpeg to be miscompiled.
Put FEATURES=keeptemp in your make.conf and post:

• emerge --info ffmpeg
  
• the build.log of ffmpeg
  

Keep in mind that keeptemp will not delete /var/tmp/portage/category/package/temp/, so remember to clean up later.

Something fancy in your make.conf, like that -redistributable the other day?

Where's your emerge --info? You should start with that from now on.

The assertions at the top of the build.log are weird and imply maybe using python 3.13's (buggy) JIT or maybe GIL-less/free-threaded Python. Don't do that yet.

build log:
https://bpa.st/GEXQ

I'm using python 3.12:

As _sam already said, info and log tells: python python3.13 is used. This does not match your emerge python output...

Note that USE=-* is considered outside of the realms of support. If you must do it, you should state it up-front and be prepared to investigate issues yourself. Please don't waste people's time without mentioning this immediately. (BTW, "freshly installed Gentoo" normally implies "it's pretty vanilla").

Using Python 3.13 is OK (it looks here like it's being used for python-any-r1 and you don't have -r100 installed), but the warnings/errors in your log look worrying and something we should try get to the bottom of. So, the fact that 3.13 is appearing is OK, but the warnings/errors there really aren't okay and must be investigated.

We still need the log from building ffmpeg and also, in all likelihood, you to prod a bit to see how it ends up installing a broken pkgconfig file.

[Adel Ahmed]

I'm prodding around but not finding anything so far

not sure where python 3.13 is coming from, this is what I have in my make.conf:

ffmpeg build log:

[bstaletic]

Is this where the saying "if it breaks, keep the pieces" applies?
/bin/sh is not bash. It's the busybox shell. ffmpeg's libversion.sh is failing to find some applet.

I couldn't resist and installed busybox myself, with the default config.
libversion.sh works just fine.

libversion.sh is a tiny script, that relies on 3 utilities and is written without bashisms. It only needs:

• awk
• echo
  
• eval

The funny thing is, busybox comes with its own implementation of all of those, but the GNU stuff is also in @system.

[logrusx]

@bstaletic I didn't understand what you mean

@Adel Ahmed:

[bstaletic]

@logrusx

From the build log:

@Adel Ahmed, now that @bstaletic mentions busybox, is this some kind of a multimedia system intended to be used as a multimedia player/TV/entertainment system?

Also you didn't answer how you get root privilege.

Amazing guess Zucca, I did that for ash not awk.
to fix it I added this line:
