Recently, I’ve been attempting to update some plots of mine, transferring my code from CMSSW_3_3_1 to CMSSW_3_6_2

[edit] 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.



I assume you run from the ROOT prompt? If so, call
root [] .except
to turn off CINT’s exception catching. Or attach gdb (to root.exe, even on linux!) and type

catch throw
