MySQL 5.7 Reference Manual  /  ...  /  comp_err — Compile MySQL Error Message File

4.4.1 comp_err — Compile MySQL Error Message File

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 MySQL is built. It compiles the errmsg.sys file from the text-format error information file located at sql/share/errmsg-utf8.txt in MySQL source distributions.

comp_err also generates the 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:
