Getting ready for LLVM’s world

In the Technical requirement section, we already listed which version of tools you needed to work with LLVM 20.1.0. However, LLVM is a lively project and what is required today may be different than what is required tomorrow. Also, to step back a bit, you may not know why you need these tools to begin with and/or how to get them.

This section addresses these questions, and you will learn the following in the process:

The purpose of each required tool
How to check that your environment has the proper tools
How to install the proper tools

Depending on how familiar you are with development on Linux/macOS, this setup can be tedious or a walk in the park.

Ultimately, this section aims to teach you how to go beyond a fixed release of LLVM by giving you the knowledge required to find the information you need.

If you are familiar with package managers (e.g., the apt-get command-line tool on Linux and Homebrew...
