[graphene] please disable neon for armv7h

Postby MastaG » Sat Jan 07, 2023 7:14 pm

Hi there,

The graphene library will segfault on armv7h devices when compiled with neon (default).
See: https://github.com/ebassi/graphene/issues/215
Just alter the PKGBUILD with only for armv7h: $this->bbcode_second_pass_code('', '-D arm_neon=false')

And please build the gnome-shell package as well.
See: viewtopic.php?f=15&t=16304

We graphene fixed and gnome-shell we can finally run a desktop on all armv7h devices again :D

You guys say 32bit arm is still supported, then please put in a little effort :)

I'm not saying we should remove the neon from the general build flags.
Just fork the graphene package and put something like:
$this->bbcode_second_pass_code('', '
if [ "${arch}" == "armv7h" ]; then
EXTRAFLAGS="-D arm_neon=false"
fi
')

Even redhat puts this flag for armv7h.
The thing is you can't support an architecture, if you dont put any specific fixes.
