Hello, please apply following command to the package SPECfile: sed -i "s/mysql-devel/mariadb-connector-c-devel/" $(fedpkg gimmespec) ; \ sed -i "s/mariadb-devel/mariadb-connector-c-devel/" $(fedpkg gimmespec) ; \ sed -i "s/%{_libdir}\/mysql/%{_libdir}\/mariadb/" $(fedpkg gimmespec) ; I've tested, that after the command ^ the package builds successfuly in KOJI and uses mariadb client library. This change is currently applicable to the Rawhide (f28) only. For more information check the tracking bugzilla.
