What version of bitcoin-core are you using?

Version v0.15.0.1, commit fb7b52938

Machine specs:

• OS: Archlinux 4.13.11-1-ARCH LSB Version: 1.4 Release: rolling

Any extra information that might be useful in the debugging process.

openssl version: openssl-1.1.0.f-2 boost-libs version: boost-libs-1.65.1-1

@azavalla check https://git.archlinux.org/svntogit/community.git/tree/trunk/PKGBUILD?h=packages/bitcoin - that is what is available if you use the community/bitcoin-daemon pacakage. Nevermind, saw #11602

The issue, as @azavalla indicated in #11602, is that OpenSSL made a backwards-incompatible API change, seemingly without deprecation notice. It also resulted in other projects (like PostgreSQL) not building, so they may revert it, but we should update to handle the new API either way.

@TheBlueMatt I just saw that, and was about to redact my suggestion.

What are the steps to reproduce? I tried to install the version mentioned in OP and it appears to work:

$ sudo pacman -U https://archive.archlinux.org/packages/o/openssl/openssl-1.1.0.f-2-x86_64.pkg.tar.xz
...
Packages (1) openssl-1.1.0.f-2
...
$ make
...
  CXX      libbitcoin_util_a-util.o
  AR       libbitcoin_util.a
  CXXLD    bitcoind

They added back the constants here: https://github.com/openssl/openssl/pull/1266 / https://github.com/openssl/openssl/commit/dd850bcb395753a130a5d69697092d69555b6e2c

So looks like any 1.1.0 release build should work.
