I'm trying to run a simple test program to understand using TOrdCollection and TOrdCollectionIter and having a problem. When I run the code, it gets to main's closing brace and gives me an endless stream of: Fatal in <TClass::TClass>: ROOT system not initialized aborting Fatal in <TClass::TClass>: ROOT system not initialized aborting .... The code is: #include <iostream.h> #include "TROOT.h" #include "TOrdCollection.h" #include "TH1.h" int main() { TROOT root("name","title"); TOrdCollection * coll = new TOrdCollection(3); TH1D* h1 = new TH1D("name1","title1",100,0.0,500.0); TH1D* h2 = new TH1D("name2","title2",100,0.0,500.0); coll->AddLast(h1); coll->AddLast(h2); TOrdCollectionIter iter(coll); cout<<((TNamed*)iter.Next())->GetName()<<endl; cout<<((TNamed*)iter.Next())->GetName()<<endl; if (iter.Next() == 0) cout << "yes" << endl; return 0; } If I comment out the three lines with cout in them, I don't get any errors. This is all on Windows NT under MS VC++ 6.0. If I compile and run on Unix (SGI), I don't get any problems either way. Am I missing something?
