NAME

       comp_err - compile MySQL error message file

SYNOPSIS

       comp_err [options]

DESCRIPTION

       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 file located at sql/share/errmsg-utf8.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[1].

       Invoke comp_err like this:

           shell> comp_err [options]

       comp_err supports the following options.

       •   --help, -?

           Display a help message and exit.

       •   --charset=dir_name, -C dir_name

           The character set directory. The default is ../sql/share/charsets.

       •   --debug=debug_options, -# debug_options

           Write a debugging log. A typical debug_options string is d:t:O,file_name. The default is
           d:t:O,/tmp/comp_err.trace.

       •   --debug-info, -T

           Print some debugging information when the program exits.

       •   --header_file=file_name, -H file_name
