Setting VERILATOR_ROOT to the root of your checkout will fix the problem.

Wilson, something about this changed at 84a2cd0 (Remove some old DIRPROJECT dead code.). I used to run tests out of the tree without having to set VERILATOR_ROOT as well. It appears that's what this code that was purged used to do. It seemed a logical default to assume VERILATOR_ROOT is the current repo you're in if the environment variable is not set. Is it reasonable to reinstate this behavior?

Ahmed, thanks for the report.

Todd, thanks for pointing out the commit. Yes, part of that removal should have been kept.

Fixed in git towards 4.020.
