Subject: RFC: pulseaudio vs. meson vs. neon
To: Patches and discussions about the oe-core layer <openembedded-core@lists.openembedded.org>
Content-Type: text/plain; charset="UTF-8"

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. In the commit text it is evidenced:

"
With Meson there's no option for disabling Neon optimizations if the
compiler supports Neon. If -mfpu is set in CC or CFLAGS, it's ignored,
because the build system adds -mfpu=neon at the end of the compiler
command line, overriding any earlier -mfpu options. This shouldn't be
a problem, because PulseAudio detects at runtime whether the CPU
supports Neon instructions.
"

At the moment to build pulseaudio for armv4/5 I have reverted to using
autotools.


There was around a patch but has not been merged.
https://lists.openembedded.org/g/openembedded-core/message/146375

Maybe a v2 will be accepted?

Cheers
A.A.
