Help understanding some error messages
A few weeks ago we ported Mu2e Offline to run with art v2_04_00.
Everything appears to be working correctly but there are some error messages that I just noticed. The occur at the start of a job and have the form:
Error in cling::AutoloadingVisitor::InsertIntoAutoloadingState: Missing FileEntry for MCDataProducts/inc/PhysicalVolumeInfo.hh requested to autoload type mu2e::PhysicalVolumeInfo
where the class name is the name of a class that is part of a data product. I have not checked very carefully but I believe that every class that is part of a data product seen by the job is present among the error messages.
The full set of error messages is attached as the file log.err
My guess is that we are not correctly building the dict and/or rootmap files and, at runtime, the system does not find a class, issues an error message and then tries a corrective action that succeeds.

We believe this is best solved by sitting down with you and looking at the
rootmap files. If there's a time today or tomorrow to do so, that would be preferable.

I can confirm that the problem is understood and that setting ROOT_INCLUDE_PATH correctly fixes the problem.
The problem occurs when:
1) Build the code rooted in directory A
2) Copy the code so that it's root is now in directory B
3) Run the code with pwd other than B
This happens when we build code on Jenkins, install in cvmfs and run the release in cvmfs from my own directory.
Adding the directory B to the tail of ROOT_INCLUDE_PATH fixes the problem.
