Introduction

FASTJET is a C++ library for jet clustering and substructure analysis. It is widely used in high-energy physics for event reconstruction and analysis. However, installing FASTJET on a Mac(ARM) running OSX Sequoia 15.3.1 can be challenging due to the specific architecture and dependencies required by the library. In this article, we will guide you through the process of installing FASTJET on your Mac(ARM) using pip.

Troubleshooting the Installation Error

When you run pip install fastjet, you may encounter the following error:

configure: exit 1
Traceback (most recent call last):
    ...

This error is caused by a failure in the build process of FASTJET. The error message indicates that the configure script has exited with a non-zero status code, which is typically an indication of a build failure.

Understanding the Error Message

The error message provides a detailed stack trace of the build process, which can be helpful in identifying the root cause of the issue. In this case, the error message indicates that the ./autogen.sh script has failed to execute successfully.

Fixing the Installation Error

To fix the installation error, you need to ensure that the ./autogen.sh script is executed successfully. This script is responsible for generating the necessary build files for FASTJET. Here are the steps to fix the installation error:

Step 1: Install the Required Dependencies

Before installing FASTJET, you need to install the required dependencies, including cmake and swig. You can install these dependencies using the following commands:

brew install cmake swig

Step 2: Install the CGAL Library

FASTJET requires the CGAL (Computational Geometry Algorithms Library) to be installed. You can install CGAL using the following command:

brew install cgal

Step 3: Install FASTJET

Once the dependencies are installed, you can install FASTJET using the following command:

pip install fastjet

Additional Tips and Tricks

Here are some additional tips and tricks to help you install FASTJET successfully:

Use a virtual environment: It is recommended to use a virtual environment to install FASTJET. This will help you isolate the dependencies and avoid conflicts with other packages.
Update your pip: Make sure that your pip is up-to-date by running the following command:

pip install --upgrade pip
