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.
