# 2021-08-05: Asterisk's own install_prereq (below) handles essentially all of these
# - name: Asterisk - Install dependencies
#   include_tasks: asterisk_dependencies.yml

# BEWARE: 'systemctl is-active asterix' falsely reports 'inactive' even when systemd
# is compiled in below!   FWIW: /opt/iiab/asterisk/contrib/systemd/asterisk.service
# https://github.com/asterisk/asterisk/blob/master/contrib/systemd/asterisk.service

- name: Asterisk - Install package 'libsystemd-dev' so Asterisk compiles in imperfect-but-improving systemd support -- if ./configure below places '#define HAVE_SYSTEMD 1' in /opt/iiab/asterisk/include/asterisk/autoconfig.h -- please later confirm with 'ldd /usr/sbin/asterisk | grep systemd' -- per https://community.asterisk.org/t/systemctl-start-asterisk-is-fail-with-timeout/81123/3
