Hello, Below is a simple macro I have a problem with on SunOS 5.5 Root v2.20/06 compiled under SunOS 5.4. First, it returns an error Error: Can't call TTree::SetAutoSave() in current scope FILE:/export/home/lijowski/ace/cris/flight/root/fits/./test_Tree.C LINE:17 *** Interpreter error recovered *** But when I comment this line, the macro crashes in line 26 with a message error in <TFile::TFile>; file does not exist. Am I missing anything? Thank you for any hints. Regards Michal Lijowski void test_Tree() { gROOT -> Reset(); // Create a new ROOT file to contain tree Int_t comp = 1; // compress file Int_t bufsize = 32000; TFile *tfile = new TFile("test_Tree.root", "recreate"); // file is compressed tfile -> SetCompressionLevel(comp); // Create a new Tree with branches TTree *TT = new TTree("TT", "test tree"); TT -> SetAutoSave("1000000000"); // autosave when 1 GB is written // create branches Int_t EventNo = 0; TBranch *br0 = TT -> Branch("EventNo", "Event Number", &EventNo, bufsize, comp); for (EventNo = 0; EventNo < 10; EventNo++) { TT -> Fill(); } tfile -> Write(); }
