COMP_ERR(1) MySQL Database System COMP_ERR(1) نام (NAME) comp_err - compile MySQL error message file خلاصه دستور (SYNOPSIS) comp_err [options] توضیحات (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 text-format error information in MySQL source distributions: 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. comp_err also generates the mysqld_error.h, mysqld_ername.h, and mysqld_errmsg.h header files.
