Any intuition or solution? Many thanks

Hi,

Given your compilation errors, it looks like ROOT was not properly installed before compiling Delphes.

Cheers,
Michele

Hi Michele,

The ROOT should have been well configured as :
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

and it runs all fine the ROOT.

So any other intuition or solution?

best,
Shu

Have you tried to configure ROOT as it's recommended on the ROOT download page?

Here is the page:
​https://root.cern.ch/drupal/content/production-version-534

and were are the commands:

. /afs/cern.ch/sw/lcg/external/gcc/4.8/x86_64-slc6/setup.sh
. /afs/cern.ch/sw/lcg/app/releases/ROOT/5.34.32/x86_64-slc6-gcc48-opt/root/bin/thisroot.sh
