Choosing ROOT installation for Delphes use

Asked by Nitish Polishetty

Hi everyone,

Sorry in advance if this question has an extremely simple solution that I just overlooked...
I had to update my MacOS version recently, and consequently was forced to update my ROOT version from 6.26.10 to 6.30. While madgraph appears unaffected, Delphes now no longer works properly. Through some testing I found that it was struggling to work between 6.26 and 6.30, and after temporarily moving version 6.26 to a different location, it appears that delphes is still trying to access 6.26 and therefore failing. How can I configure it such that delphes works with version 6.30 instead?

Thanks in advance.

Hi,

We are neither ROOT expert nor Delphes expert, so this is not the most appropriate place for such question.
My guess is that if you want Delphes to link to a new ROOT version it should either work (looks like not) or that you need to recompile it.

Maybe they are better solution, but you should ask Delphes author if needed.

Cheers,

Olivier
