Hi Paul,

Thank you for your reply. What you tell would explain the behavior. Is there a way to deactivate those caches, or some other way to guarantee that make checks a target's existence right before it executes its rule?

Regards,

Simon.

It sounds like an issue with make's directory cache.  Make internally
caches the contents of directories and updates its cache information
based on the targets that your makefile says exist.

So if a rule in your makefile creates a file that is not listed as a
target, make's internal cache doesn't know about it because your rule
didn't list it as a target that would be created by running that
command.
