FAQ: RDK Docker Toolchain - rdkcentral/ut-core GitHub Wiki

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

• rdk-dunfell
• rdk-kirkstone

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.

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

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.
