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 plaintext file
located at sql/share/errmsg.txt in MySQL
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]
