From 34bf473e19118eecf525e7401ef37b1cbf661e67 Mon Sep 17 00:00:00 2001 From: orbea Date: Sat, 9 Sep 2023 06:49:56 -0700 Subject: [PATCH] configure: disable engines if OPENSSL_NO_ENGINE is defined Starting with LibreSSL 3.8.1 the engines have been removed which causes the OpenVPN build to fail. This can be solved during configure by checking if OPENSSL_NO_ENGINE is defined in opensslconf.h.
