I have a simple makefile as below. Even though the $(STATUS) value is 1
the ifeq doesnot gothrough this condition. I am using Gmake 3.80
on linux.
btc6l001$ gmake -f bg.mk
1
PASS
1 --BG
all:
$(eval STATUS := $(shell ls blahblah> nul 2>&1 ;echo $$?))
@echo $(STATUS)
ifeq ($(strip $(STATUS)),1)
@echo "FAIL"
@echo "$(STATUS) --BG1"
else
@echo "PASS"
@echo "$(STATUS) --BG"
endif
That's because the ifeq is evaluated when the Makefile is read in (i.e.
before any commands are run) and at that point STATUS has not been
defined and hence does not equal 1 and hence the all rule gets the else
portion and will be defined as:
all:
$(eval STATUS := $(shell ls blahblah> nul 2>&1 ;echo $$?))
@echo $(STATUS)
@echo "PASS"
@echo "$(STATUS) --BG"
