Errors while installing Delphes

[Pablo]

Hello,
I'm trying to install Delphes-3.4.2 on ubuntu 20 and I'm getting this in the terminal:

[Pavel Demin]

This problem is fixed in the latest version (3.5.0). Please try to use the latest version. It can be downloaded from the following link:
​http://cp3.irmp.ucl.ac.be/downloads/Delphes-3.5.0.tar.gz

[Pablo]

Thank you for the answer! Now I'm trying with that version and once I'm inside the Delphes folder and I run makr, I get this:

doc/Makefile.arch:19: * Please make sure root-config can be found in path. Stop.

I have root installed in /usr/local and the root-config file is in /usr/local/root/bin, but it seems that Delphes is not able to find it.

Do you have any suggestion?

Thanks in advance

[Pavel Demin]

Do you have any suggestion?

Try to install ROOT following the instructions from ​this link.

[Pablo]

Thank you, that worked! However, now I'm trying to install Delphes on ubuntu 18 and I got this:

In this computer I have also installed root as you said for ubuntu 20

[Pavel Demin]

I think you need to install a version compatible with Ubuntu 18. It can be downloaded from the following link:

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

[Pablo]

Yes, sure. I have installed the one that appears for ubuntu 18 in that link. Also, root is launching when I type root in the terminal.

[Pablo]

Sorry, now it worked. It was because of a previously installed version of root. Thanks a lot for your help!
