From 2e230e8687486b71c113915b864d6b1f6d465ed1 Mon Sep 17 00:00:00 2001 From: "Dr. Matthias St. Pierre" Date: Tue, 30 Jan 2018 23:53:57 +0100 Subject: [PATCH] crypto/rand/rand_lib.c: fix undefined reference to `clock_gettime' Some older glibc versions require the `-lrt` linker option for resolving the reference to `clock_gettime'. Since it is not desired to add new library dependencies in version 1.1.1, the call to clock_gettime() is replaced by a call to gettimeofday() for the moment. It will be added back in version 1.2.
