_SSL_COMP_free_compression_methods i.e. SSL_COMP_free_compression_methods is marked as ** deprecated** since OpenSSL 1.1.0k (see https://www.openssl.org/news/cl110.txt ). Since this symbol is not exported anymore with default OpenSSL build as by the Macports or OpenSuse OpenSSL packages, any usage of SSL enabled boost::asio and boost::beast will fail.

Possible duplicate of !96 but I thought since this is a request and the other is a bug report, this issue will trigger another process. Also !96 was by building with an additional build flag, I think the fact that this behaviour is now produced by simple default builds by package managers is new.

This issue was moved by chriskohlhoff from boostorg/asio#214.
