gnumake

I have a tricky issue with gmake, when I build from the parent directory, something is different and the make does not build all the .o(s) it needs and fails, but if I cd to the directory and do a make it builds them fine.

How can I get GNUmake to tell me the difference between these two runs? There must be some make variables set in the parent that break the child, but I need help figuring out how to track them down.

On a Cisco device, I know that enabling debugging can incur a performance hit since debugging has such a high priority on the CPU.

Why does Gnumake from parent directory behave differently?
