Archlinux template build fails: 'readdir_r' is deprecated

[Dimitri]

I didn't build the archlinux template for a long time. Once it worked as described here https://www.qubes-os.org/doc/templates/archlinux/ but now it fails with this error (for 3.1 and 3.2):

libxl_utils.c: In function 'libxl__remove_directory':

How can I fix this? Ignoring the deprecation? Replace readdir_r with a non deprecated alternative?

Thanks for help!

I built the archlinux template yesterday and ran into the same problem.
I had to modify /etc/makepkg.conf and add "-Wno-deprecated-declarations"
to CFLAGS.

That's not enough however as I also had to bind mount /dev/pts on the
chroot because gpg was failing when installing packages. I poked around
in various scripts and somehow got to it work.

Thanks. Modifying /etc/makepkg.conf was sufficient!
