Compilation error during make. (with root 6.24.06)
It seems to be due to TDirectory::operator= which is deleted.

QnAnalysis/src/QnAnalysisObservablesEK/na61/na61.cpp:352:31: error: use of deleted function ‘ROOT::Internal::TDirectoryAtomicAdapter& ROOT::Internal::TDirectoryAtomicAdapter::operator=(const ROOT::Internal::TDirectoryAtomicAdapter&)’
  352 |                  gDirectory = cwd;

Solution:
Use TDirectory* cwd = gDirectory; everywhere in the file.

edit:
Suggestion of ROOT team to use TContext
