You can't. Every recursive invocation of make is a separate process, every process has its own set of variables, and the variable settings in that process cannot be passed back to the parent process. Just like when you start a new shell and change a variable there, it cannot propagate back up to the process that invoked the shell. -- ------------------------------------------------------------------------------- Paul D.
