Cannot install Delphes on MacOS Monterey

[Steven Ferrante]

Hi,

I’m trying to install Delphes (I have macOS Monterey 12.0.1) by either using

curl -O http://cp3.irmp.ucl.ac.be/downloads/Delphes-3.2.0.tar.gz
tar -xf Delphes-3.2.0.tar.gz
cd Delphes-3.2.0/
make

or by typing “install Delphes” inside the MagGraph environment, but neither work for me. Initially I had ROOT 6.24, but saw in a post (​https://answers.launchpad.net/mg5amcnlo/+question/697395) that trying ROOT 6.20 instead of 6.24 should work (for a MacOS slightly older than the one I have). I tried getting ROOT 6.20.08 from ​https://root.cern/releases/release-62008/, but this still gave me errors.

Below is the output I get when I type "install Delphes" into a MadGraph environment (this is when I had ROOT 6.20.08):

I think that MacOS 12.0 is too recent to be usable with ROOT:

​https://root-forum.cern.ch/t/root-6-24-06-can-not-work-on-macos-monterey/47409
​https://root-forum.cern.ch/t/root-fails-after-upgrade-to-macos-monterey-12-0-1/47494

It would be easier to install ROOT on MacOS 11.5 using the pre-built binary packages:

​https://root.cern/releases/release-62406/

Delphes-3.2.0 is a very old version.

Please try the latest Delphes version from the following link:

For information. I have tested ROOT 6.24.06 and the latest Delphes version from GitHub on a MacBook with the M1 processor.

Everything works in the x86_64 emulation mode (Rosetta 2). I have installed ROOT via the brew package manager and the latest Delphes version from the following link:
