Install a Real or Virtual Linux Machine

If you don't already have a Linux machine, you can set one up in several different ways. You can install a Linux distribution natively, either on its own machine or as a dual-boot system. You can install Linux on a virtual machine on, say, a Windows host machine. You can also use Windows Subsystem for Linux (WSL), available on Microsoft Windows 10, which allows you to run a Linux distribution with an emulation layer substituting for the Linux kernel.

We recommend using the Ubuntu distribution of Linux or one of its variants (Kubuntu, Mint, etc.). The instructions here assume you are using Ubuntu. The 20.04 LTS (Long Term Support) version is stable and reliable.

Native Linux

You can install Ubuntu on a bare machine easily. Follow the directions (this link is for 20.04) on the Ubuntu website. You can also install Ubuntu on a disk shared with your Windows installation, or on a separate disk, and make a dual-boot installation.

Linux on a Virtual Machine

Linux can also be installed easily on a virtual machine. First you install the virtual machine software, and then create a new virtual machine, usually giving the VM software a .iso file of Ubuntu or another distribution. On Windows, VM Workstation Player and VirtualBox are both free and easily installed.

Vagrant

Vagrant is software that is designed to make it easy to set up and use pre-configured virtual machines. There are potential stumbling blocks. This guide will include Vagrant information in the future.

Install Build Tools on Ubuntu

The Ubuntu 20.04 LTS Desktop distribution includes most of what you need to build CircuitPython. First, in a terminal window, do:

Download: file
sudo apt update
# Try running `make`. If it's not installed, do:
# sudo apt install build-essential
sudo apt install git
sudo apt install gettext
pip3 install huffman

Next you need to download and unpack the ARM gcc toolchain from its download page. ARM is no longer updating its Ubuntu "ppa" (private package archive), so you need to install these manually.

Download: file
# Put the unpacked toolchain into an appropriate directory.
# This is an example.
cd ~/bin
tar xvf <name of the .bz2 file you downloaded>

Next, add a line to your .bash_profile or other startup file to add the unpacked toolchain executables to your PATH. For example:

Download: file
export PATH=/home/$USER/bin/gcc-arm-none-eabi-9-2019-q4-major/bin:$PATH

Open a new terminal window, and see if you now have the correct executables on your path:

Download: file
$ which arm-none-eabi-gcc
/home/halbert/bin/gcc-arm-none-eabi-9-2019-q4-major/bin/arm-none-eabi-gcc

Now move to the Build CircuitPython section of this guide.
