Hello, MariaDB went through big changes and your package will need a patch in order to build and work properly. I tried to solve the issue, but I wasn't successful yet (at the time of bug creation). I'll look into it more and post here the patch eventualy. This change is currently applicable to the Rawhide (f28) only. You can check builds I tried in COPR: https://copr.fedorainfracloud.org/coprs/g/db-sig/mariadb-10.2/packages/ For more information check the tracking bugzilla.
