Reading that along with the other comment explains what we are seeing with a .SECONDARY without any prerequisites. BTW I also tried with a very simple Makefile to rule out any roles that implicit rules might be playing. If I create a Makefile like below: final: sfinal cp sfinal final sfinal: qfinal cp qfinal sfinal qfinal: touch qfinal If I build fully and then remove file "sfinal", subsequent make will recreate that file. But if I add a ".SECONDARY:" target without any prerequisites, "sfinal" will not be recreated.
