Difficulties building RTEMS

Wed Sep 16 08:54:05 UTC 2015

I followed the guide "Getting started with RTEMS". But I've found a solution : I introduced the "creat()" in libgloss. And then I figured out than other functions were missing to (opendir, closed, readdir,...)

How did you install the toolchain?
