Dear Maintainer, Please stop linking against libmysqlclient_r and link directly against libmysqlclient instead. Your package currently links against libmysqlclient_r. libmysqlclient_r was the thread-safe version of libmysqlclient in previous MySQL releases. However, libmysqlclient has been itself been made thread-safe since before the current libmysqlclient18. Thus libmysqlclient_r is currently deprecated and provided as a compatibility symlink only, and will disappear in MySQL 5.7. This change can be made now, in advance of a possible future transition to libmysqlclient20, which does not provide the _r variant. In Ubuntu, we have done this with the attached quilt patch, which I believe is also applicable to Debian. Thanks, Robie Basak Debian MySQL maintainers team Ubuntu developer
Description: Use mysqlclient instead of mysqlclient_r The mysqlclient_r used to be the thread safe version of mysqlclient, but in both 5.5 and 5.6 mysqlclient was also thread safe and the two were equivalent, and in 5.7 mysqlclient_r was removed.
