ACLiC compilation error

Dear Root experts

since a couple of days, I have an error while running root on my .cpp file. I never had this problem before on the same code.
The error is:

[himali10@cmslpc01 ALL_USEFUL_TOOLS]$ root -l process_all_.cpp+
root [0]
Processing process_all_.cpp+…

Error in : Compilation failed!
Error: Function process_all_() is not defined in current scope :0:

Does the error related to root or CINT? I am expecting support to fix the issue.
