-n
Create the directory but don’t compile Build switch
The -n
switch is
not strictly a part of the
Build program. Instead, it is
just passed to the make(1)
program, and the Build program
creates the obj directory (if
it doesn’t exist), and then populates it with a
Makefile and symbolic links.
After that, Build invokes
make with the -n
switch, which only
causes make to print what it
would do. It doesn’t cause make
to actually do anything.
This -n
switch is
especially useful with the install
target, to preview what steps
will be undertaken to install the program before
actually installing it.
