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 text−format error information in MySQL source distributions:
• As of MySQL 8.0.19, the error information comes from the messages_to_error_log.txt and messages_to_clients.txt files in the share directory.
For more information about defining error messages, see the comments within those files, along with the errmsg_readme.txt file.
• Prior to MySQL 8.0.19, the error information comes from the errmsg−utf8.txt file in the sql/share directory.
comp_err also generates the mysqld_error.h, mysqld_ername.h, and mysqld_errmsg.h header files.
Invoke comp_err like this:
