Command Line Tools

To compile our own software, we need to install the Command Line Tools from Apple. Alternatively, you can install Xcode — Apple's complete development environment for macOS. Xcode is available as a free download from the Mac App Store.

First, launch Terminal from Applications ➤ Utilities.

Install the Command Line Tools. This will initiate the installer. Follow the on-screen instructions.

xcode-select --install

Verify that you have successfully installed the Command Line Tools.

xcode-select -p

This command displays the location where your developer tools are installed.

Once you have the developer tools installed, you are ready to begin installing your own custom built packages.
