Debugger: Errors at searching path for included makefiles

[TaiwanMadao]

I have a directory [aaa] with Makefile & sub-directory as illustrated.

(The directory was compressed and please download from aaa.tar.gz )

At the beginnig, invoke remake in folder [aaa].
In folder [aaa], Makefile[1] would be read , and invoke remake in foler [bbb] with searching path added (-I'absolute_path'/aaa).
In folder [bbb], Makefile[2] would be read, include another.mk in folder [aaa] with searching path, and invoke remake in folder [ccc].
In folder [ccc], Makefile[2] would be re-read again, and include anotther.mk in folder [aaa] with searching path.
Without debugger, all is fine; however, with debugger step by step executed, the the path of included another.mk in Makefile[2] is wrong at first (but still includable) in folder [bbb]. Finally, in folder [ccc], the another.mk in Makefile[2] is not includable and debugger catch an error.

The following is the message given by remake. I also print the variable [.INCLUDE_DIRS] in every recipe in Makefile[1] & [2] to inspect the searching path of included files. It seems that the searching path was not correctly added to sub-folders.

Personally, this something I am not going to have time for in the foreseeable future.

And probably not something I'm that interested in until such time as I encounter this problem (if ever).

If you are others are interesting in invesigating, please do!
