Which dependency is causing rebuild?

johnu · 04-21-2010, 03:00 PM

Is there a way to determine which dependency is causing a file in a kbuild makefile to run? (I've fixed my directory woes, but some of the files are still rebuilding and I want to know why!)

I'd also be interested to know if there's someway of doing this with a regular makefile as well.

Thanks

John

I don't use kbuild, but GNU make dependencies can be checked with: make -d

Or to check only, and don't actually build: make -n -d

It generates a LOT of output, and it can be hard to locate what you need to know.
