No discovery of source from makefile

[JohnBrown]

Trying to follow devzone.nordicsemi.com/.../ but whatever I do, I am unable to make Eclipse discover the include paths or the source file paths from the makefile. I've been round and round in circles on this for most of the day(not to mention previous attempts), and I still can't make any sense of it. Is it because I have Eclipse Luna, rather than Kepler? It's driving me crazy! I've added the line in the makefile that's supposed to echo the file paths, and I've done (I think) everything else as specified in the link.

In case it helps, here is what I get when restarting Eclipse:
