Hi,

Which error is reported? Like this no clue what the problem can be.
Note that in general Delphes installation problem are not handle by us but by Delphes author.
So even if you paste the error here, it is likely that my answer will be "Ask Delphes author"
But this should not refrain you to post the error, maybe this is something that I know how to fix.

Cheers,

Olivier

Hi Olivier,

Thanks your

I just tried 2 ways.

1. Writing install Delphes code is displayed that error.

MG5_aMC>install Delphes
Command "install Delphes" interrupted with error:
InvalidCmd : The environment variable ROOTSYS is not configured.
 You can set it by adding the following lines in your .bashrc [.bash_profile for mac]:
 export ROOTSYS=/usr
 export PATH=$PATH:$ROOTSYS/bin
 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ROOTSYS/lib
 export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:$ROOTSYS/lib
 This will take effect only in a NEW terminal.

2. Second one is downloading from source.

wget http://cp3.irmp.ucl.ac.be/downloads/Delphes-3.2.0.tar.gz
tar -xf Delphes-3.2.0.tar.gz
cd Delphes-3.2.0/
make
>> Generating tmp/classes/ClassesDict.cc
Error: cannot open file "TLorentzVector.h" classes/DelphesClasses.h:38:
Error: Symbol TLorentzVector Momentum,Position,Area is not defined in current scope classes/DelphesClasses.h:466:

Error: rootcint: error loading headers...
Makefile:1975: recipe for target 'tmp/classes/ClassesDict.cc' failed
make: *** [tmp/classes/ClassesDict.cc] Error 1

Hi,

So did you include the line:
"
> export ROOTSYS=/usr
> export PATH=$PATH:$ROOTSYS/bin
> export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ROOTSYS/lib
> export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:$ROOTSYS/lib
"
in your .bashrc profile (or better the one suggested by root when you install it)

The problem is that without those lines, Delphes is not able to find root library needed to be compiled.

Cheers,

Olivier
