comp_err creates the errmsg.sys file that is used by mysqld to
determine the error messages to display for different error
codes. comp_err normally is run automatically when MariaDB is
built. It compiles the errmsg.sys file from the plaintext file
located at sql/share/errmsg.txt in MariaDB source distributions.
comp_err also generates mysqld_error.h, mysqld_ername.h, and
sql_state.h header files.
For more information about how error messages are defined, see
the MySQL Internals Manual.
Invoke comp_err like this:
shell> comp_err [options]
