Paul,
Thank you and appreciate your help. I missed this point (in fact
always
misunderstood this, I assumed that the dependency is 1-1 pair wise ie.,
foo -> fee only
and so on...). So, this is really not an issue but my
mis-understanding. Apologize
for the noise.... ; Also explains the other noticed effects of why it
is updating the
file 3 times.
Do you have any idea on how to achieve what I want?. I really want
to have 1-1
dependency and yet not want to write each one of them separately. Is it
Ok if I ask this question
here ? or take it elsewhere?
pals

If you write a rule like:
foo bar biz : fee fie foe
then make interprets that to mean EXACTLY the same thing as:
foo : fee fie foe
bar : fee fie foe
biz : fee fie foe
This explains your problem, I believe, since every target in
$(EXPORTED_HDRS) lists ALL the files in $(EXPORT_HDRS) as a
prerequisite, and so will be considered out of date if ANY file in
$(EXPORT_HDRS) is newer, and each target will be updated.
