Error: symbol mysql_get_server_name, version libmysqlclient_16 not defined

If you see the error message:

symbol mysql_get_server_name, version libmysqlclient_16 not defined in file with link time reference

...then you are probably trying to use the mysql command-line client from MariaDB with from MySQL.

The symbol mysql_get_server_name() is something present in the MariaDB source tree and not in the MySQL tree.

If you have both the MariaDB client package and the MySQL client packages installed this error will happen if your system finds the MySQL version of first.

To figure out which library is being linked in dynamically (ie, the wrong one) use the 'ldd' tool.

ldd $(which mysql) | grep mysql


ldd /path/to/the/binary | grep mysql

For example:

me@mybox:~$ ldd $(which mysql)|grep mysql => /usr/lib/ (0xb74df000)

You can then use your package manager's tools to find out which package the library belongs to.

On CentOS the command to find out which package installed a specific file is:

rpm -qf /path/to/file

On Debian-based systems, the command is:

dpkg -S /path/to/file

Here's an example of locating the library and finding out which package it belongs to on an Ubuntu system:

me@mybox:~$ ldd $(which mysql)|grep mysql => /usr/lib/ (0xb75f8000)
me@mybox:~$ dpkg -S /usr/lib/
libmariadbclient16: /usr/lib/

The above shows that the mysql command-line client is using the library /usr/lib/ and that that library is part of the libmariadbclient16 Ubuntu package. Unsurprisingly, the mysql command-line client works perfectly on this system.

If the answer that came back had been something other than a MariaDB package, then it is likely there would have been issues with running the MariaDB mysql client application.

If the library that the system tries to use is not from a MariaDB package, the remedy is to remove the offending package (and possibly install or re-install the correct package) so that the correct library can be used.
