From 61d962bdfdb9ca13e5f31e726ae84823c6f68fc6 Mon Sep 17 00:00:00 2001 From: Andrew Bartlett Date: Thu, 12 Mar 2015 17:01:05 +1300 Subject: [PATCH] lib/tls: Fix behaviour of --disable-gnutls and remove link to gcrypt We no longer link against gcrypt if gnutls > 3.0.0 is found, as these versions use libnettle.
