Hi rooters, If I follow the TROOT object declaration as explained on it's web page (http://root.cern.ch/root/html/TROOT.html) it doesnt work for me : ----- #include <TROOT.h> #include <TFile.h> #include <TTree.h> #include "C_brut_plastic_data.H" // <-- This is my ROOT class TROOT root_stuff("test","test analysis"); void toto(void); main() { toto(); } void toto(void) { TFile *root_file; TTree *orion_events; C_brut_plastic_data brut_plastic_data; root_file = new TFile("toto.root","RECREATE","Orion events"); orion_events = new TTree("orion_events","Orion manip events"); orion_events->Branch("brut_plastic","C_brut_plastic_data",&brut_plastic_data); } ---- I compile the main and C_brut_plastic_data.cpp, create the dictionary, compile it and link. But... The complain is when I create the branch : Warning in <TClass::TClass>: no dictionary for class C_brut_plastic_data is available If now I just change the status of 'root_stuff', passing it from a static object to a local object of main : ----- #include <TROOT.h> #include <TFile.h> #include <TTree.h> #include "C_brut_plastic_data.H" // <-- This is my ROOT class void toto(void); main() { TROOT root_stuff("test","test analysis"); toto(); } void toto(void) { TFile *root_file; TTree *orion_events; C_brut_plastic_data brut_plastic_data; root_file = new TFile("toto.root","RECREATE","Orion events"); orion_events = new TTree("orion_events","Orion manip events"); orion_events->Branch("brut_plastic","C_brut_plastic_data",&brut_plastic_data); } ---- The code seems to work and there's no warning anymore. I dont really understand why... Did I miss something ?
