Using this file:
all:
alpha.p beta.p:
touch $@
%.c %.h: %.p
touch $*.c $*.h
alpha.o: alpha.c alpha.h beta.h
touch $@
beta.o: beta.c beta.h alpha.h
touch $@
executable: alpha.o beta.o
touch $@
all: executable
First create all targets:
$ make
touch alpha.p
touch alpha.c alpha.h
touch beta.p
touch beta.c beta.h
touch alpha.o
touch beta.o
touch executable
Remaking all targets depending on beta.p:
$ touch beta.p
$ make --dry-run
touch beta.c beta.h
touch alpha.o
touch beta.o
touch executable
$ make
touch beta.c beta.h
touch alpha.o
touch beta.o
touch executable
Both with and without --dry-run has the same result.
But trying to do the same with alpha.p:
$ make --dry-run
touch alpha.c alpha.h
touch alpha.o
touch executable
$ make
touch alpha.c alpha.h
touch alpha.o
touch beta.o
touch executable
You see that --dry-run is missing 'touch beta.o'.
