Package: mysql-5.6 Version: 5.6.28-1 Severity: serious The mysql-5.5 source package produces the libmysqlclient18 shared library, main file being libmysqlclient.so.18. So does the mysql-5.6 package too (even using the same "18" version string oddly, are there no changes in the ABI?).
It seems the mysql-5.5 never shipped a symbols file. In mysql-5.6 there is a specific Lintian override about not shipping the symbols file: http://anonscm.debian.org/cgit/pkg-mysql/mysql-5.6.git/tree/debian/libmysqlclient18.lintian-overrides The Debian policy states "shared libraries must provide either a symbols file or a shlibs file" at https://www.debian.org/doc/debian-policy/ch-sharedlibs.html For implementation tips see also: https://wiki.debian.org/UsingSymbolsFiles For examples you can also check libmariadb2 symbol file: http://anonscm.debian.org/cgit/pkg-mysql/mariadb-client-lgpl.git/tree/debian/libmariadb2.symbols The mariadb-5.5 package used to have a symbols file some years ago in Debian until it was denied from shipping a libmariadbclient package, but it can never the less be used as an example too: http://anonscm.debian.org/cgit/pkg-mysql/mariadb-5.5.git/tree/debian/libmariadbclient18.symbols Please do the following things: 1) Drop the Lintian override immediately. This problem should not be hidden on purpose. 2) Add the symbols file and start tracking symbols. 3) If there are problems with the symbols changing from release to release, please address it in appropriate ways, e.g. dump the soname from .18 to .18.1 or .19 or what is most fit. Thanks!
