It's difficult to answer without knowing what your makefile does. I would guess you need to define rules telling make how to generate the .d files as targets, so that make can regenerate them when they are missing. Alternatively, use "-include" to include the .d files, which does not give an error if they are missing. Read the documentation on "include" by running "info make Include" for more information, or in the online manual at http://www.gnu.org/software/make/manual/html_node/Include.html
