Delphes installation in Madgraph

[Chang]

Hi,

After adding the following lines to .bash_profile on my mac,
export ROOTSYS=/opt/local/libexec/root5
export PATH=$PATH:$ROOTSYS/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ROOTSYS/lib
export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:$ROOTSYS/lib

When installing Delphes with "install Delphes", it said,
Command "install Delphes" interrupted with error:
IOError : [Errno 2] No such file or directory: './Delphes/Makefile'
Please report this bug on ​https://bugs.launchpad.net/mg5amcnlo
More information is found in 'MG5_debug'.
Please attach this file to your report.

Could you please tell me what I can do now?

Thanks,
Chang

Have you tried reporting to the mad graph launchpad?
We don't support directly Delphes installations within MG5.
Besides, you could try to run Delphes in standalone mode, which is pretty easy, and explained here:

Hi,

I tried again by installing Delphes fold in standalone mode and put that fold in the Madgraph directory. Everything worked well in Madgraph, I got tag_1_delphes_events.root. However, in root,

when typing:
gSystem->Load("libDelphes")

There is bug:
Error in <TMacOSXSystem::DynamicPathName>: libDelphes[.so | .dll | .dylib | .sl | .dl | .a] does not exist in :/opt/local/libexec/root5/lib::/opt/local/libexec/root5/lib::.:/opt/local/libexec/root5/lib/root::/opt/local/
libexec/root5/lib/root/cint/cint/stl
(int)(-1)

And i found that there is no libDelphes in my root.

Could you please tell me what I need to do now?

Thanks,
Chang

try to add delphes installation location to the PATH variable. Something like

PATH=$PATH:path_to_delphes_installation

where you replace "path_to_delphes_installation" the actual path.
