MySQL 5.7 Reference Manual Including MySQL NDB Cluster 7.5 and NDB Cluster 7.6
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:
