In this example,
sub/q.d is same as sub2/q.d
sub/z.d is different from sub2/z.d
target def's output is what I expect.
target all's output is not. I expect
q.d same
z.d diff
How do I fix?
$ cat makefile
define Diff
$(shell diff $(1) $(2) 1>/dev/null 2>&1; [ $$? -ne 0 ] && echo 1)
endef
all: def
for f in q.d z.d; do echo $$f $(if $(call
Diff,sub/$$f,sub2),diff,same); done
def:
@echo q.d $(call Diff,sub/q.d,sub2)
@echo z.d $(call Diff,sub/z.d,sub2)
$ make
q.d
z.d 1
for f in q.d z.d; do echo $f diff; done
q.d diff
z.d diff
Thanks
James
