I have one general question, and one precise one:
first the general question:
libPhysics.so used to be included in the root binary for root 2.22
and is not anymore in root 2.23:
*******************************************

*******************************************
CINT/ROOT C/C++ Interpreter version 5.14.24, Nov 21 1999
Type ? for help. Commands must be C++ statements.
Enclose multiple statements between { }.
root [0] TLorentzVector tv
Error: No symbol TLorentzVectortv in current scope
FILE:/var/tmp/baaydaWsx_cint LINE:1
*** Interpreter error recovered ***
root [1] .L $ROOTSYS/lib/libPhysics.so
root [2] TLorentzVector tv
root [3]
Some other attractive Classes that can be found in the documentation
are not by default in the binary:
root [0] TAttParticle pa
Error: No symbol TAttParticlepa in current scope
FILE:/var/tmp/caaK4ayZx_cint LINE:1
*** Interpreter error recovered ***
root [1] .L $ROOTSYS/lib/libEG.so
root [2] TAttParticle pa
root [3]
Is this on purpose ? Why ?
--
Also, I am puzzled by the following:
root [3] TAttParticle::DefinePDG()
root [4] TIter next(TAttParticle::fgList);
root [5] TAttParticle *par;
root [6] par = (TAttParticle *)next()
(class TAttParticle*)0x5b4248
root [7] par->Print()
Particle: down
Mass: 0.005000 DecayWidth: Stable Charge : -0.333333
root [8] par->GetName()
(Text_t* 0x5b49cc)"down"
root [9] TAttParticle::fgList->FindObject("down")
(class TObject*)0x0
root [10] TAttParticle::GetParticle("down")
Error in <THashList::GetParticle>: No match for down exists !
(class TAttParticle*)0x0
root [11]
There must be something simple I am missing.
