       comp_err - compile MySQL error message file


       comp_err [options]


       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.

       o   --help, -?

           Display a help message and exit.

       o   --charset=dir_name, -C dir_name

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

       o   --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.

       o   --debug-info, -T

           Print some debugging information when the program exits.

       o   --header_file=file_name, -H file_name

           The name of the error header file. The default is mysqld_error.h.

       o   --in_file=file_name, -F file_name

       o   --name_file=file_name, -N file_name

       o   --out_dir=dir_name, -D dir_name

           The name of the output base directory. The default is

       o   --out_file=file_name, -O file_name

           The name of the output file. The default is errmsg.sys.
