I am actually writing simulation library in c++ and I would like to save the output data in a TTree.
In this simulation software, 2 class are involved in my problem:
one call ZAI (which correspond to a nuclei, which references , its Z, A, and its isomeric state)
and one call IsotopicVector, wich correspond to a composition of ZAI, which contain a map<ZAI, int>
I think I made the appropriate inheriting : ZAI and Isotopic vector are public TObjet, and have a ClassDef & ClassImp (in .h and .c respectively).
I generate the root Dictionary and include it into my library
The program compile and run without any error.
In root after loading my library, I can open the generated root file without any error message.
but when I try to read the map, they are empty…
I try to check if the problem comes from my side by adding a vector of long int (vector) in the IsotopicVector. (The long int here, are not necessary… but I use it in the real program…)
And this vector is correctly filled and ridden when the map remains empty…
So I wonder, if I made a mistake in branching my IsotopicVector on my TTree, or if their is some “special treatment” to do in order to fill correctly a map in the TTree or…
I join an .tar archive to this mail, containing :
- a simplified source of my library (only the ZAI and Isotopicvector Class)
- the makefile I used
- a small piece of code showing the problem as describe previously (where I print the IsotopicVector before filling it to be sure it is not empty)
- the small macro I used to check if it’s working
I use :
- DELL latitude E6420 (intel i7 quad core)
- gcc version 4.6.1 (Ubuntu/Linaro 4.6.1-9ubuntu3)
- "ROOT 5.32/00 (tags/v5-32-00@42375, Dec 02 2011, 12:42:25 on linuxx8664gcc)
- CINT/ROOT C/C++ Interpreter version 5.18.00, July 2, 2010"
- And I am running on a Ubuntu system : 11.10 64 bits
After compiling my 2 class, I do the following command :
> g++ -o Test test.cpp -I ./source/include/ -I ${ROOTSYS}/ -L ./ -lCLASSpkg `root-config --libs`
> ./Test
> root
root [0] .L libCLASSpkg.so
root [1] .L read.C
root [2] TFile *_file0 = TFile::Open(“Test.root”)
root [3] read(Data)
I hope I am clear enough, If not please tell me, I can provide any information you could need…
Thank you for your time,
Baptiste,
PS : I hope my approximative English is understandable…
