It would help if you showed us the exact command that ended up with that bunch of errors... however, having seen this before, I'm going to venture a guess that you either didn't include '-lssl' in your linking command, or got the order between '-lcrypto' and '-lssl' wrong. However, seeing the actual command will help clear this, rather than having to guss...
