If that's true then OpenSSL v1.1.0 is failing the backward compatibility it claims to provide and I'd think that would be a bug against OpenSSL. Until OpenSSL v1.1.0 is part of all currently supported standard distros (Ubuntu 16.10 still uses v1.0.2g) we cannot compile ODP against those higher levels for distribution. If you compile against the older version then it should work against an installed copy of v1.1.0 as noted above since v1.1.0 is backwards-compatible. > > -- > With best wishes > Dmitry
