The build environment

The first thing to note is that I have seen your build environment is important, I have found dockers even with Linux to be tricky, if you know how to share the memory between dockers and your host, great stuff, if not, use a Linux machine (virtual or real). Windows with dockers was always tricky and eventually why I moved over to having ubuntu on my personal laptop and also build PC.

My suggestion is to build directly on a machine, I’ve used Ubuntu 20.04 on an ARM processor. You will also need the following for sure:

• Linux based machine
• 4GB RAM
• 300GB Hard disk space (preferably 200GB free)
• A good internet connection
• Good CPU access/multiple cores

You’ll also need to setup a swapfile so you have more RAM, otherwise you’ll hit an error about cc1plus at big compilations like GCC. You’ll probably already have a swapfile so start by running through the “Removing a swap file” section of this article and then go back and run from the start:

Next, let’s get yocto’s dependancies as well:
