by on

If you're involved in scientific research or data analysis, you've likely heard of CERN ROOT. Developed by CERN (the European Organization for Nuclear Research), ROOT is an essential toolkit for high-energy physics data analysis. In this guide, we'll walk you through the process of installing CERN ROOT on your Ubuntu machine. 

Prerequisites

Before we dive into the installation process, make sure you have the following prerequisites in place:
  • A working Ubuntu machine (this guide is tested on Ubuntu 23.04, but it should work on other versions as well).
  • Sudo privileges to install packages.

Downloading CERN ROOT

Start by downloading the latest version of CERN ROOT from the official website or open your terminal and use the following command to download the source code:

wget https://root.cern/download/root_vX.YY.Z.source.tar.gz

Replace X.YY.Z with the version number you want to install (e.g., 6.22.08).

Installing Dependencies

CERN ROOT relies on several libraries and tools. To ensure a smooth installation, install the necessary dependencies:

sudo apt-get install dpkg-dev cmake g++ gcc binutils libx11-dev libxpm-dev \
libxft-dev libxext-dev python libssl-dev

You can also install the optional dependencies:

sudo apt-get install gfortran libpcre3-dev \
xlibmesa-glu-dev libglew-dev libftgl-dev \
libmysqlclient-dev libfftw3-dev libcfitsio-dev \
graphviz-dev libavahi-compat-libdnssd-dev \
libldap2-dev python-dev python-numpy libxml2-dev libkrb5-dev \
libgsl0-dev qtwebengine5-dev

Building CERN ROOT

Now, let's build CERN ROOT from the source code. Here are the steps:

  • Extract the downloaded tarball:
          tar -xzvf root_vX.YY.Z.source.tar.gz

  • Create a build directory and navigate into it:
            mkdir root-build
            cd root-build

  • Run cmake to configure the build:
          cmake ../root-X.YY.Z

Replace X.YY.Z with the version you downloaded.

Troubleshooting

If you encounter any issues during the installation process, refer to the official CERN ROOT documentation or community forums for troubleshooting tips.

Conclusion

Congratulations! You've successfully installed CERN ROOT on your Ubuntu machine. You're now ready to harness the power of this essential toolkit for your scientific data analysis projects. Remember that CERN ROOT has extensive documentation and a vibrant user community, so don't hesitate to explore further.

C Program to Add of Two Numbers

by on
The following program performs the arithmetic operation of adding two numbers and prints their sum on the screen. In this example, the user must input two numbers. Declare the Variables: The first step in adding two numbers using C programming is to declare the variables that will store the values of the two numbers. In C programming, we can declare variables using the syntax:  data_type variable_name;  For example, to declare two variables that will store the values of the two numbers, we can use the following code: int num1, num2; Get Input from User: After declaring the variables, we need to get the input from the user. To do this, we can use the scanf() function. The scanf() function reads the input from the user and stores it in the variables. Here is the code to get the input from the user: printf("Enter the first number: "); scanf("%d", &num1); printf("Enter the second number: "); scanf("%d", &num2); Add the Numbers:   Now that we ...
