Linking Delphes-3.10 to MG5

Hi,

I have open a ticket on the Delphes web-site:
https://cp3.irmp.ucl.ac.be/projects/delphes/ticket/249

> I have already installed Delphes-3.10 a while back with other datasets. Is there a way to connect this Delphes to MG5 or solve the error above?

you can define where Delphes is install in the file
input/mg5_configuration.txt

Cheers,

Olivier

Dear Dominic,

Looking at the error message, I'd say that some system header files are missing on your computer.

A similar problem (Error: cannot open file "AvailabilityMacros.h") is mentioned on the ROOT forum:

​http://root.cern.ch/phpBB3/viewtopic.php?f=3&t=17190&start=75

The solution was to install the latest xcode and command line tools. It's also suggested to run 'xcode-select --install' after re-installing xcode.

Could you, please check the following?

  - latest xcode and command line tools are installed
  - ROOT installation is built for your current OS
  - correct ROOT installation is used when you build Delphes
  - following commands show the same correct location of your ROOT installation

       root-config --libs
       which root-config
       which root

   - the following command returns correct architecture (most probably macosx64)

       root-config --arch

Regards,

Pavel

I've just updated http://cp3.irmp.ucl.ac.be/downloads/Delphes-3-current.tar.gz.

Now it points to Delphes-3.0.12.

HI Pavel (and Olivier)

Many thanks for your reply, I've managed to point MG to my current version of Delphes.

Thanks again.

Best regards,

Dominic

Hi Pavel,

I'd just like to add that a colleague had the same problem and indeed doing "xcode-select --install" worked.

Thanks once again.

Best regards,

Dominic

Thanks a lot for this.
