If you use several levels of recursive
make invocations, the
-w’ or ‘
--print-directory’ option can make the output a
lot easier to understand by showing each directory as
starts processing it and as
make finishes processing it. For
example, if ‘
make -w’ is run in the directory
make will print a line of the form:
make: Entering directory `/u/gnu/make'.
before doing anything else, and a line of the form:
make: Leaving directory `/u/gnu/make'.
when processing is completed.
Normally, you do not need to specify this option because ‘
does it for you: ‘
-w’ is turned on automatically when you use the
-C’ option, and in sub-
make will not
automatically turn on ‘
-w’ if you also use ‘
-s’, which says to
be silent, or if you use ‘
--no-print-directory’ to explicitly
