Indeed, from https://www.freedesktop.org/wiki/Software/PulseAudio/Notes/14.0/ " One difference from Autotools is that the --disable-neon-opt option for disabling NEON optimizations doesn't have a counterpart in Meson due to how Meson's NEON detection works. NEON will always be enabled if the compiler supports it, but even if the target machine doesn't support NEON, that shouldn't be a problem, because PulseAudio disables NEON at run-time if the processor doesn't support it. " Upstream *thinks* this is not an issue because all will be fine at runtime :) Cheers A.A: > > Alex > > On Mon, 28 Jun 2021 at 12:02, Andrea Adami <[email protected]> wrote: >> >> Hello, >> >> during a core-image-sato build for armv4 I got one single build >> failure with pulseaudio. >> >> This happens after commit 80bbea0 pulseaudio: switch build system from >> Autotools to Meson.
