It seem like pushing the make down into a shell script produces the correct behavior. For example, a build.sh:

So you’re saying that the issue is that I invoke make directly in cron not in a terminal? And that having cron instead invoke a shellscript that in turn invokes make should fix this?
Or am I misunderstanding this?
