Makefile sequential execution

Question

I have the following Makefile:

all: generate print # <-- doesn\'t work

date: 
    date > date.txt

ls:
    ls -la > ls.txt

generate: ls date

prin         


        

Answer 1

Just add the pipe symbol:

all: | generate print

From the make manual:

Order-only prerequisites can be specified by placing a pipe symbol (|) in the prerequisites list: any prerequisites to the left of the pipe symbol are normal; any prerequisites to the right are order-only:

targets : normal-prerequisites | order-only-prerequisites
