Hello.

I can't build my system, build fails on opus package.

Target board specs:
Licheepi nano
f1c100s SOC
arm926t (armv5tej) architecture
Thumb instructions enabled, build is ok when building using regular ARM instruction set.

I don't even know why buildroot is building opus, i've disabled ffmpeg and other opus tools.

(In reply to Evgeny from comment #0)
Hello;

It looks like opusfile is still selected in your config which depends on opus.

You can check the reverse dependencies of a selected package with:

make ${pkg}-graph-rdepends


My suggestion would be to unselect opusfile in target packages -> libraries -> audio/sound and then unselect opus in the same place.

Comment 2 Evgeny 2020-06-26 11:52:54 UTC

Thanks, didn't notice that.

libavcodec also blocks build process btw.
