So it seems libruby.so uses its own statically linked openssl, and exports those symbols so they are available to other applications. Maybe modifying the linker commandline to provide -lcouchbase before -lruby would help? I’m not entirely sure. Your best bet is to build the library without openssl (requires CMake, use ./cmake/configure —disable-ssl). Follow the instructions for building from source on the README (https://github.com/couchbase/libcouchbase <https://github.com/couchbase/libcouchbase>). Remember to git checkout 2.5.1 before building in order to get a stable release version.
