I’m trying to read ROOT files from Python, but I get errors for some fields (that I don’t use), so I wanted to create a dictionary. I don’t have the complete working program on my laptop, but I have source files for the Event class (part of our collaboration code), and I tried to generate a dictionary for that class.
$rootcint -f DCEEvent_dict.cc -c DCEEvent.hh LinkDef.h

_Please read [tips for efficient and successful posting](https://root-forum.cern.ch/t/tips-for-efficient-and-successful-posting/28292) and [posting code](https://root-forum.cern.ch/t/posting-code-read-this-first/28293)_
Sorry, this is probably a very large output, but I decided to put it complete.
So the problem is that rootcling generates a dict (without visible errors), but then this dict can’t be used by ROOT. I think there is an error somewhere in between, and maybe I could fix that? Is that a ROOT bug? Thanks for your ideas.
