From 0230e2e374bb71aed0181ccd9ebd13c0c5125a5d Mon Sep 17 00:00:00 2001 From: Trevor Woerner Date: Fri, 25 Oct 2019 17:01:20 -0400 Subject: [PATCH] configure.ac: add library if header found If the pthread.h header is found, make sure library containing "pthread_atfork" is added to the list of libraries against which to link. On some hosts (e.g. openSUSE 15.1) "-lpthread" needs to be explicitly added in order for the code to compile correctly.
