Hello, please apply following command to the package SPECfile: sed -i "s/community-mysql-devel/mariadb-connector-c-devel/" $(fedpkg gimmespec) ; I've tested, that after the command ^ the package builds successfuly in KOJI, however in any case (before or after patch) it does not use the mysql / mariadb client library, which mostly indicates it does not mysql at all. Please check it and remove the Buildrequires entirely, if I'm right. This change is currently applicable to the Rawhide (f28) only. For more information check the tracking bugzilla.
Thanks for a bug report. I replaced it, rather than removed, because the removal also means to change configure.ac. Even it might not be needed, because the package omits the server part and installs only the client side, I think it's safer to bring in the build dependency than carry another patch.
