How To Install root-roofit on CentOS 8
Introduction
In this tutorial we learn how to install root-roofit on CentOS 8.
What is root-roofit
The RooFit packages provide a toolkit for modeling the expected distribution of events in a physics analysis. Models can be used to perform likelihood fits, produce plots, and generate “toy Monte Carlo” samples for various studies. The RooFit tools are integrated with the object-oriented and interactive ROOT graphical environment. RooFit has been developed for the BaBar collaboration, a high energy physics experiment at the Stanford Linear Accelerator Center, and is primarily targeted to the high-energy physicists using the ROOT analysis environment, but the general nature of the package make it suitable for adoption in different disciplines as well. This package contains the RooFit toolkit classes.
We can use yum or dnf to install root-roofit on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install root-roofit.
Install root-roofit on CentOS 8 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
The output should look something like this:
