I was dreaming for a tutorial like your, and it comes true ! Many thanks, all is clearly understandable. I was struggling for weeks to get programs compiled for RS97, with no success (I'm new to Linux). My biggest mistake was using Raspbian (wich I feel comfortable with), but not understanding that it was 32bits environment made things difficult, as Steward is using 64bits system. So I followed your tutorial, installed fresh 17.10 Ubuntu and now I hope I will eventually success (right now toolchain is compiling for + 4 hours !). Thanks again I'm very grateful.
