Cannot build Delphes2 with MadGraph on lxplus.cern.ch

[Shu Li]

Dear Delphes experts,

I have a problem building up Delphes2 on the lxplus.cern.ch platform.
What I did was:

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

then inside MadGraph, I did:
mg5>install Delphes

compile Delphes. This might takes a while.

then ended up with the errors as the following:

Compiling Utilities/stdhep/mcf_stdcm1_xdr.c

/usr/bin/ld: cannot find -lEG

make: * [lib/libUtilities.so] Error 1
Error detected during the compilation. Please check the compilation error and run make manually.

Any solution? Many thanks.

Hi,

sorry for the late answer. Please use Delphes 3 (Delphes2 is not supported anymore).

Cheers,
Michele
