From daa88b765111b14047c97256bd2a9a2daabe123b Mon Sep 17 00:00:00 2001 From: Christoph Biedl Date: Mon, 5 Dec 2016 20:26:00 +0100 Subject: Fix building ngIRCd with OpenSSL 1.1 At the moment, ngIRCd fails to build against OpenSSL 1.1 since the configure check probes for the SSL_library_init symbol which was removed, but probing for a different function availabe in both versions solves that problem: SSL_new(). And as SSL_library_init is no longer needed, the patch boils down to probing SSL_new to assert libssl is available, and disabling the SSL_library_init invokation from OpenSSL 1.1 on, see also another application[1] (NSCA-ng) that did pretty much the same. Patch was compile-tested on both Debian jessie (OpenSSL 1.0.2) and stretch (OpenSSL 1.1). [1] (Patch by Christoph, commit message cherry-picked from the email thread on the mailing list by Alex.
