Hi,
In order to use TLorentzVector you __first__ need to include the physics
library (which implements the lorentz vector):
root [] gSystem->Load("libPhysics");
Cheers,
Philippe

Subject: [ROOT] TLorentzVector
I wasn't successful using TLorentzVector with v3_02_07c or v3_03_07d on
Linux-2-4 using KCC-4.
I get errors like:
Warning: Re-initialization ignored const kMaxInt

*** Interpreter error recovered ***
When I load my macro in root session.
I just want to get the invariant mass of two jets using the M() method. My
macro works just fine if I don't make use of LorentzVectors.
Thanks for any help.
