TSpectrum:: a problem

Roofit and RooStats

Hello,
I am trying to use TSpectrum::Search () function in a .cc code
I added the TSpectrum.h, but when I run it, it says undefined reference to TSpectrum::TSpectrum()
Should I add another library? And if so how?

Many Thanks

Eda

No, because I don’t know how to link it.
Actually I am running a shell program and inside it, it runs a .py code with cmsRun, and inside the py program it runs the .cc code
so How can I link it?

[quote]so How can I link it?[/quote]It is not very clear how you ‘run’ things (you may want to request advise from the group supporting cmsRun), but it is likely that just executinggSystem->Load("libSpectrum");will solve the problem.
