Read problem on ULong64_t data type

Hi:
Could someone help me on reading the ULong64_t data type?
I attached the c++ program and the root file I used.
Basically, there is no problem when I run it in the root CINT, for both ULong64_t and Float_t. When compiling c++ program standalone,

g++ check_commonhash.C -o check_commonhash `root-config --cflags --libs` -std=c++11

and run ./check_commonhash, the error pops up for ULong64_t. But no problem for Float_t. Strange.

tree->Print()” says:

*Br    0 :CommonEventHash : CommonEventHash[2]/l                             *

so you need “ULong64_t commonhash[2]”.

Wonderful! I can’t thank you enough.
Didn’t realize that it’s an array.
