Per supported platforms doc, the various min glib on relevant distros is: RHEL-7: 2.50.3 Debian (Stretch): 2.50.3 Debian (Jessie): 2.42.1 OpenBSD (Ports): 2.54.3 FreeBSD (Ports): 2.50.3 OpenSUSE Leap 15: 2.54.3 Ubuntu (Xenial): 2.48.0 macOS (Homebrew): 2.56.0 This suggests that a minimum glib of 2.42 is a reasonable target Signed-off-by: Daniel P.
