Each of those which checks is testing to see if a particular tool is installed. In your first post the error is a missing SDx installation. This was required for earlier versions of the build flow but now we ship the precompiled objects as part of the repository. You can safely remove line 310 of the makefile to delete this check. We’ll update this is in the next version. Your second post is failing on vivado which means you haven’t sourced the settings.sh in that shell.
