with_path "Integ" update_thy "Main";

Theory loader: cannot update finished theory "Main"

What does this message mean? Why, when I change a theory file, can I
sometimes do update_thy without problems, and sometimes not? When is a
theory "finished"?

Thanks for any help

After finishing a session, i.e. when usedir has succefully compiled
everything. You can bootstrap HOL interactively like this:

- copy HOL/ROOT.ML to HOL/root.ML
- replace with_path "Integ" use_thy "Main";'' by add_path "Integ";''
- delete the subsequent lines
- start Isabelle Pure
- issue ``use "root.ML"''

Now you can assert arbitrary theories from the HOL sources.
