A new OS, Fuchsia, getting started

August 19, 2022

Getting started Fuchsia

Fuchsia is a modern open source operating system that’s simple, secure, updatable, and performant. It provides core operating system functions like system resource management, a driver framework, and software abstractions. Fuchsia is a general purpose operating system designed to power a diverse ecosystem of hardware and software.

But currently(19th of Aug, 2022), it doesn’t support Apple silicon officially.

1. Setup build environment

Jiri

Jiri is a tool for multi-repo development. It supports:

syncing multiple local GIT repos with upstream,
capturing the current state of all local repos in a “snapshot”,
restoring local project state from a snapshot, and
facilitating sending change lists to Gerrit.

Install dependencies

brew install wget pkg-config glib autoconf automake libtool golang

Install Jiri

Jiri: manage git repositories

git clone https://fuchsia.googlesource.com/jiri
cd jiri
go install ./cmd/jiri

Bootstrapping

export MY_ROOT="$JIRI_REPO"
curl -s https://fuchsia.googlesource.com/jiri/+/HEAD/scripts/bootstrap_jiri\?format\=TEXT | base64 --decode | bash -s "$MY_ROOT"
# cipd bootstrapped to path:"$JIRI_REPO/.jiri_root/bin/cipd"
