Problem Installing Delphes

[Tathagata Ghosh]

Hi Delphes Experts,

I encountered the following error after using the "make" command, while installing Delphes:

"Error: cannot open file "TLorentzVector.h" classes/DelphesClasses.h:24:
Error: Symbol TLorentzVector Momentum,Position,Area is not defined in current scope classes/DelphesClasses.h:452:
Warning: Error occurred during reading source files
Warning: Error occurred during dictionary source generation
!!!Removing tmp/classes/ClassesDict.cc tmp/classes/ClassesDict.h !!!
Error: rootcint: error loading headers...
make: * [tmp/classes/ClassesDict.cc] Error 1"

I guess the problem is due to ROOT. However ROOT is installed in my computer and it is properly running.

Please help me to solve the problem.

Thanks in advance,

Tathagata

Hi Tathagata,

Could you provide more details about your system (OS version, ROOT version, how you installed ROOT)?

Could you also check that 'TLorentzVector.h' can be found in the directory returned by
'root-config --incdir'?

Regards,

Pavel
