FAQ: RDK Docker Toolchain

Launching the Toolchain Docker Container

This manual guides you through the process of using the RDK Docker Toolchain to build projects targeted for ARM architecture, using Docker.

Note: At the time of writing this has yet to be published opensource, but will be soon

To start the Docker container and open a bash shell within it, use the following command:

sc docker run <docker> /bin/bash

Expected Dockers

• rdk-dunfell
• rdk-kirkstone

Setting Up the Environment

Once inside the Docker container, follow these steps to set up the environment:

1. Navigate to the toolchain directory:

cd /opt/toolchains/rdk-glibc-x86_64-arm-toolchain/

2. Source & Activate the environment setup for ARMv7:

. environment-setup-armv7at2hf-neon-oe-linux-gnueabi

3. To verify that the compiler (CC) is set correctly in the environment, execute:

echo $CC

The output should start with arm-oe-linux-gnueabi-gcc followed by various compiler switches.

Building the Project

To build your project using the ARM toolchain, follow these steps:

• Change to your project directory (replace with your actual project directory name):

cd <project>

• Start the build process by specifying the target:

make TARGET=arm

Optional Single Command Execution

Alternatively, you can combine all the steps into a single command to set up the environment and build your project directly. Here’s how:

e.g.

sc docker run rdk-dunfell "/bin/bash -c '. /opt/toolchains/rdk-glibc-x86_64-arm-toolchain/environment-setup-armv7at2hf-neon-oe-linux-gnueabi; cd <project>; make TARGET=arm'"

Make sure to replace with your actual project directory. This command facilitates running everything in one go inside the Docker container.
