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
