go-brillo's Introduction

Go on Brillo

jbd's notes on Go development on Brillo devices.

Goals

Make GOOS=android working on Brillo boards by using the BDK toolchain.
Publish libbinder bindings to enable services written in Go.
Publish bindings for the HAL layer.
Add GOOS=android/{arm,386} BDK toolchain builds to the Go build dashboard and maintain CI devices.

Guides

Build Go binaries targeting Brillo

Note: You need to have BDK installed before beginning.

Install the prebuilt standard library, targeting both ARM and 386 devices:
