“can’t open the fdp output file linkorderfile” warning is seen during oracle binary link on HP Unix.
This problem can happen if you invoke “make -f $ORACLE_HOME/rdbms/lib/ins_rdbms_mk ioracle” from directory different from $ORACLE_HOME/rdbms/lib
The problem can happen on scripts tha call “ins_rdbms.mk ioracle”, for example, the “chopt” script can hit this problem.
Workaround
“cd $ORACLE_HOME/rdbms/lib” and rerun the command.
