I am trying to use eclipse IDE (on ubuntu 20.04) with RIOT for openmote-b hardware platforms. I am following  for the required settings in eclipse. But it seems I am missing something and hence not able to build (“hello-world” program) (fails at Project→Build All - step 6 of the tutorial). Any help/pointers are highly appreciated and thanks very much for your time! My build output is given below.
P.S.: I can build and flash the motes from the ubuntu terminal.
