COMP_ERR(1)

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

    • --in-file=file_name, -F file_name The name of the input file that defines error messages. The default is ../sql/share/errmsg-utf8.txt.

    • --name-file=file_name, -N file_name The name of the error name file. The default is mysqld_ername.h.

    • --out-dir=dir_name, -D dir_name The name of the output base directory. The default is ../sql/share/.

    • --out-file=file_name, -O file_name The name of the output file. The default is errmsg.sys.

    • --state-file=file_name, -S file_name The name for the SQLSTATE header file. The default is sql_state.h.
