Looking at the error message:

In file included from tmp/external/ExRootAnalysis/ExRootAnalysisDict.cc:63:
tmp/external/ExRootAnalysis/ExRootAnalysisDict.h:18:10: fatal error: 'G__ci.h' file not found
#include "G__ci.h"

I'd say that the problem is with the ROOT installation.

G__ci.h should be in $ROOTSYS/include. If compiler doesn't find G__ci.h, then either the file isn't installed or ROOTSYS isn't set.

Could you try to go through the following checklist:

• $ROOTSYS points to your ROOT installation
• root-config --cflags returns correct path to the ROOT's include directory ($ROOTSYS/include)
• G__ci.h is in the ROOT's include directory
