Eclipse preprocessor coloring code from a file or makefile? [message #1016325]

I am developing a c code for embedded application using makefile and Eclipse and I want to add some external global symbols or preprocessor to Eclipse indexer, because I want to use the coloring unused code feature from Eclipse.

Is it possible to instruct Eclipse to look for global symbols from a file instead of defining them manually in "path & symbols -> Symbols"?

Thanks,
Ricardo.

- Open Project Properties and go to C/C++ General->Preprocessor Include Paths, Macros
- In the Entries tab select "CDT User Settings Entries" in the right window and the click "Add" (see attached screenshot).
- In the appearing dialog choose "Preprocessor Macros file" from the dropdown menu in the top left corner.
- select the file

To be honest, I never used this option myself. But I think it should work as expected.
