No, you doesn't. See below

libmariadbclient.a is a static version of libmariadb.so.
both are the MariaDB Connector/C - new LGPL MariaDB/MySQL client
library, see https://mariadb.com/kb/en/mariadb/mariadb-connector-c/
libmysqlclient is the old GPL MariaDB/MySQL client library. It's no
longer developed, all new features go into MariaDB Connector/C.
libmysqlclient is removed in 10.2
Either way, you need either libmysqlclient or libmariadb, you should not
link with both at the same time.

Use either one, but not both.
