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.
Qt is not compatible with MariaDB Connector/C: https://bugreports.qt.io/browse/QTBUG-63108 (This was filed against Qt 5 and 4, but probably applies to Qt 3 too.)
We probably need to backport: https://codereview.qt-project.org/#/c/205874/
backported the fix for qt3, it's now included in qt3-3.3.8b-72.fc28
