hi,
I have a
question that I was hoping someone could answer. I am trying to understand which
characters have special significance in a rule command section and which
participants are involved in processing them.
For example,
given
target: dep1.ext dep2.ext dep3.ext
command --opt1 val1 etc..
how can you
predicate which characters will be given special significance? It seems the
section of text after the rule header is processed by make itself before being
passed to the underlying shell?
At the moment, I'm
aware that the following may do some textual processing before passing the
commands on to the next layer
(1) Make
(2) A shell (or can tools sometimes be invoked direct by OS process
creation api?)
(3) The tool itself
any help
appreciated,
thanks,
Andrew
