Look at this makefile.
====
IsFileExist = $(shell if [ -f $1 ]; then echo 1; fi )
outfile = out.txt
$(outfile):
@echo "STRT: $@ $(if $(call IsFileExist,$@),exist,absent)"
@touch $@
@echo "DONE: $@ $(if $(call IsFileExist,$@),exist,absent)"
====
When outfile does not exist and we make it, make outputs
------
STRT: out.txt absent
DONE: out.txt absent
------
So we know all make-vars are expanded for all commands in a rule before
the first command of that rule is really executed. But if I really like
the example makefile to output
-------
STRT: out.txt absent
DONE: out.txt exist
-------
How can I do it? I know I can add another rule to accomplish that, e.g.
==========
IsFileExist = $(shell if [ -f $1 ]; then echo 1; fi )
outfile = out.txt
all: $(outfile)
@echo "DONE: $(outfile) $(if $(call
IsFileExist,$(outfile)),exist,absent)"
$(outfile):
@echo "STRT: $@ $(if $(call IsFileExist,$@),exist,absent)"
@touch $@
==========
But that complicates the makefile. Is there a way that I can do it with
only one rule?
Thank you in advance.
