Hi @Mohammad-Goli, it seems like something on your VOXL is prematurely closing the file descriptor attached to the process that lists the pipes - I'm not sure what that is. I'm also not getting any errors with libyaml-cpp so that could be part of the problem. I'm running on SDK version 1.3.5, so I if were you I'd re-flash your VOXL and try the install again.
Flashing the VOXL guide
Sorry I couldn't recreate your issue. If you're still having a problem after re-flashing, let me know what SDK you tried and I'll give it a shot on my end.
