MySQL 9.3 Reference Manual Including MySQL NDB Cluster 9.3
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.
Invoke comp_err like this:
