Question

I\'m using CoqIDE to complete the exercises in the Software Foundations book about Coq. I can successfully compile Basics.v, resulting in Basics.vo and Basics.glob in my dir

Answer 1

I have experienced this error myself. Try opening CoqIDE from the same directory where the Software Foundations files are, and compile from there. If you're on Linux, just open a terminal, go to that directory, and type coqide there. I don't quite know how to do this on other systems, e.g. Mac OS, but I did notice that just opening the app through the icon makes it fail.
