What is a .D file and why is Eclipse trying to clean it. [message #777535]

When I clean my project, I'm getting:
"/bin/rm cannot remove 'myproject.d' No such file or directory"

My clean statement from the console display shows
rm libmyproject.so myproject.d myproject.o

Where is the .d coming from and why is my project trying to clean it?

There's no significant problem here, but it is something that is annoying me at this point.

That is a dependancy file generated by the compiler. It guarantees that when you modify e.g. a header file all source files that include this header will be recompiled.

Then I would have to assume at one point, this project was creating dependency files. With that being said, I have been playing around with different versions of eclipse, and this particular project has been moved a few times, so I'm sure something broke along the way... but what broke and how do I fix it?

How do I either start building the dependency file again, or, tell the compiler to stop trying to clean it?

The dependancy file should be recreated automatically when you build your project.

It isn't.

Hm, you can try to recreate the makefile. Delete it and Eclipse will create new Makefiles. AFAIK, the dependencies are handled by the compiler options -MT and -MF. See the Makefile subdir.mk in your Debug folder.
