From 44365eb1e1165f2a44cb31f404b04cf85031718e Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Mon, 30 Oct 2023 21:39:26 +0100 Subject: [PATCH] Deactivate _FORTIFY_SOURCE in jitterentropy-base.c This fixes compilation with glibc. _FORTIFY_SOURCE only works with compiler optimizations activated. We have to deactivate it when we set -O0. This fixes the following error message with glibc: error: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Werror=cpp] musl libc does not show an error message in this case, but has the same internal problems.
