Hello,
Need some help in understaning below, please.
1. cat Makefile
.PHONY : all
ifndef $(one)
one := 1
endif
all :
@echo $(one)
$ make
$
Why does it not print 1?
Don't know, I got "1" and always use ifndef pattern in my Makefiles.
2. I am unable to find a real simple example for understanding of $(if ...).
Can someone please give one?
I use $(if ...) in such case:
cmd ... | tee .log
save output into log. To control when use loggin I define:
LOG_CMD = $(if $(VERBOUSE), | tee $(LOG))
and in command wrote:
a: b
cmd -o $@ $< $(LOG_CMD)
