link error AWS with SSL on debian 9 64 bit

["Björn Lundin" <b.f.lundin@gmail.com>]

Hi!
The following problem was posted on AWS-mailing liust 2017-08-20 and
did not receive any reply. I repost it here in hope of a bigger audience.


Having a production machine on 64 bit debian 8 I got

bnl@prod:~$ apt-cache pkgnames | grep -i libssl | sort
libssl1.0.0
libssl1.0.0-dbg
libssl-dev
libssl-doc
libssl-ocaml
libssl-ocaml-dev


and a dev machine on 64 bit debian 9 with

bnl@tp:~/svn/bnlbot/botstart/bot-1-0/source/ada$ apt-cache pkgnames |
grep libssl | sort
libssl1.0.0
libssl1.0.2
libssl1.0-dev
libssl1.1
libssl-dev
libssl-doc
libssl-ocaml
libssl-ocaml-dev
bnl@tp:~/svn/bnlbot/botstart/bot-1-0/source/ada$


To build AWS with ssl support I set

SOCKET    = openssl


in makefile.conf

Building AWS itself works on both debians but using it does not work on
debian 9

Looking around internet it seems like openssl changed a bit between 1.0
and 1.1

How is this best handled ?
