Corteca Toolchain v23.12.1

Part of Corteca Developer Toolkit, Toolchain is a set of compilation tools that help isolate the application within the container, avoiding interaction with the host system's libraries in the creation of applications for Corteca Marketplace. This repository is hosted on https://github.com/nokia/corteca-toolchain

Introduction

This repository contains the files needed to build the Corteca Toolchains. There are 2 flavors of the toolchain depending on the target CPU architecture:

Toolchain name	CPU Architecture	Indicative list of Corteca devices
corteca-toolchain-armv7	armv7, arm-el, 32-bits	Beacon 6
corteca-toolchain-armv8	armv8, aarch64, 64-bits	Beacon 10, Beacon 24, Beacon G6, XS-2426X-A, XS-2426G-B, Beacon3.1 / G-1426G-A

Both of the images are based on Buildroot v2023.02.1 and are configured for each CPU architecture. The following packages are installed by default in the target filesystem:

• Linux Kernel Headers v4.14.x
• binutils v2.37
• libc: musl v1.2.3
• gcc v10
• ubus
• mbedTLS

Prerequisites

In order to be able to build your application you need to have docker installed and create a directory structure to hold the source code and all the other files that are need for your application.

Docker

The toolchains for compiling and building the containers require docker or a compatible container engine. This document assumes that you use docker. Make sure you have docker installed.

docker --version

If this fails, please follow the installation procedure for your OS.

Sample application

In order to be able to build your application you need to create a specific directory structure to hold the source code and all the other files that are need for the container package creation. For more information on this, you can take a look at the Sample Container Application Documentation.

For instructions on using the toolchain to build your application, refer to Corteca Development Platform Documentation
