Recently, I’ve been attempting to update some plots of mine, transferring my code from CMSSW_3_3_1 to CMSSW_3_6_2
 This is running on ROOT 5.22/00d.
The code in 331 works fine, but when I run it in 362, I get the following message.
Error: Symbol G__exception is not defined in current scope ttbarLoad.C:13:
Error: type G__exception not defined
What is this telling me? I’ve tried to add an #include and it still gives me this. Any help would be greatly appreciated.
