--print-directory OptionIf 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 make
starts processing it and as make finishes processing it. For
example, if make -w is run in the directory /u/gnu/make,
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 make
does it for you: -w is turned on automatically when you use the
-C option, and in sub-makes. 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
disable it.
