Salom,

In GNU make, something like this should work

#!/usr/bin/make -f
# partial makefile to show always-rebuild for datestamp
.dummy : buildtime.c

buildtime.c :
	date +'const char buildDate[]="%a %d %b %Y %T %Z";' > $@

buildtime.o : buildtime.c
	$(CC) $(CFLAGS) -o $@ $<




The .dummy directive will make make rebuild buildtime.c on each
invocation.


If your make program doesn't support .dummy, then using
   rm $<
as the second build rule for buildtime.o will also work.


HTH,
