Fail to create LHCO events from DELPHES in Madgraph, using macOS 10.14

[shenty1991]

Hello,

I am now trying to run Delphes with madgraph_2.3.3, but it always comes out with an error in terminal:

Fail to create LHCO events from DELPHES

with the delphes_log file:

dyld: Library not loaded: @rpath/libCore.so

../bin/internal/run_delphes3: line 30: 72675 Abort trap: 6 $delphesdir/root2lhco delphes.root delphes_events.lhco

I am using root 6.14, I think it is correctly installed, since I can open root successfully in my terminal.

Any one could help me to tackle this issue? Thank you really very much!

Unfortunately, I don't have any MacOSX computer to reproduce this problem. It could be that something is wrong with the run_delphes3 script that you're using.

Could you try to build and run Delphes without using the MadGraph scripts?

Here are the commands:

wget http://cp3.irmp.ucl.ac.be/downloads/Delphes-3.4.1.tar.gz
tar -zxf Delphes-3.4.1.tar.gz

cd Delphes-3.4.1
make -j 4

curl http://cp3.irmp.ucl.ac.be/~demin/test.hepmc.gz | gunzip | ./DelphesHepMC cards/delphes_card_CMS.tcl delphes_output.root

Hi,

Thank you for your help, I already tried this, and I still get error when I try to run ./DelphesSTDHEP

I got:

dyld: Library not loaded: @rpath/libCore.so

Referenced from: /Users/shenty1991/Documents/Delphes-3.4.1/./DelphesSTDHEP
Reason: image not found

Do you know how to solve this issue?

Thank you so much!

I asked a colleague to test Delphes on his computer with MacOS 10.14.2 and clang 10. To install ROOT, we used root_v6.14.06.macosx64-10.14-clang100.dmg downloaded from ​https://root.cern.ch/content/release-61406. We could build Delphes and it worked without any problem.
