TSpectrum.h file not found

Hi experts,

I have installed locally on my laptop the version 5.34 and am trying to run a macro that uses TSpectrum.h
However when I compile the macro, this is what it says:

root [0] .L fs_dark_jet_comp.C++
Info in TUnixSystem::ACLiC: creating shared library /home/charaf/WorkingArea/HeRadiationDamageJets/Talks/./fs_dark_jet_comp_C.so

I have checked indeed in /usr/include/root/ that TSpectrum.h is not present. How can I add this functionality to my root version ?

Thanks a lot.

try :

ls $ROOTSYS/include/TSpectrum.h

It should be there.

Do you have $ROOTSYS defined ?

I dont have ROOTSYS.

I installed root doing yum install root.
