Something Is Odd. I guess I don't understand the .for .. .endfor function.
For example, I have a directory loaded with files whose names are in the form
yyyymmdd.wmi (yyyy is the four-digit year, mm is the two-digit month, and dd is
the two-digit day, with ".wmi" being the "filetype"). When I have a Makefile
that goes like this:
MONTHS = 200110 200111 200112 200201
MONTHS_WMIS = 200110.wmi 200111.wmi 200112.wmi 200201.wmi
DSTS = 200110.html 200111.html 200112.html 200201.html
all: $(DSTS)
.for MONTH in $(MONTHS)
DAY_WMIS != ls -1 ????????.wmi | grep '^'$(MONTH) | sort | uniq
$(MONTH).html: $(DAY_WMIS) $(MONTH)i.wmi
@echo "MONTHS: " $(MONTHS)
@echo "MONTH: " $(MONTH)
@echo "DAY_WMIS: " $(DAY_WMIS)
@echo "Making --> " $(MONTH).html
$(MONTH)i.wmi: $(DAY_WMIS)
ls -1 $(DAY_WMIS) | sort > $(MONTH)i.wmi
@echo "Making --> " $(MONTH)i.wmi
.endfor
and type make, I get this:
$ make
MONTHS: 200110 200111 200112 200201
MONTH: 200110
DAY_WMIS: 20020127.wmi 20020128.wmi
Making --> 200110.html
MONTHS: 200110 200111 200112 200201
MONTH: 200111
DAY_WMIS: 20020127.wmi 20020128.wmi
Making --> 200111.html
MONTHS: 200110 200111 200112 200201
MONTH: 200112
DAY_WMIS: 20020127.wmi 20020128.wmi
Making --> 200112.html
MONTHS: 200110 200111 200112 200201
MONTH: 200201
DAY_WMIS: 20020127.wmi 20020128.wmi
Making --> 200201.html
$ _
While it appears that the .for loop is working (according to MONTH), the
DAY_WMIS value doesn't change. Is there any other way to do this so that it'll
work?
