I have had a look at the topics related to filling a TTree with a vector (of floats) or with a user defined object, and succeeded in creating a dictionary from a makefile for my own class.
I have a class “Particle” (which holds a class “Point”) and I want to be able to fill the TTree with a vector without using the gInterpeter.
So far I have modified my Makefile with the following;
$(ODIR)/Dictionnary.o:$(DDIR)/Dictionnary.cpp $(CXX) $(OPTFLAG) -c -o $@ $< $(DDIR)/Dictionnary.cpp: $(HEADERS) rootcint -f $@ -c -p $^
And have included in my headers and sources the macros ClassDef(MyClass, 1) and ClassImp(MyClass).
So far I have only succeeded in dealing with my “Particle” class, I can’t seem to hold a vector, I keep on getting the error message :
Thanks in advance for your help,
PS: I am using the latest ROOT version, i.e. v5.34.18
