Thank you Paul!
Sorry for any confusions. Maybe I have not made myself fully understood. I think I mean the same as your points, > prog: foo.o bar.o > > .INTERMEDIATE: foo.o bar.o > > Now, we run make: > > cc -o foo.o -c foo.c > cc -o bar.o -c bar.c > cc -o prog foo.o bar.o > > cc -o prog foo.o bar.o > cc: no such file or directory: bar.o I think in this sample, you mean when bar.o is removed, the command "cc -o prog foo.o bar.o" will not work to generate prog, since bar.o will not be remade after deletion. Is it your points? If it is, my question is that, according to the rule in GNU make, intermediate file will be remade if they are needed, so why in this case (it seems that prog's dependency bar.o is needed) bar.o is not remade? I think make treats bar.o in this case as a file not needed? regards, George --- "Paul D.
