From 2c855b76362d1027abea967ac253cae8a7c160c3 Mon Sep 17 00:00:00 2001 From: Trevor Woerner <twoerner@gmail.com> Date: Wed, 6 May 2020 17:38:05 -0400 Subject: [PATCH] configure.ac: add library if header found (#10) 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.
