How to build amd64/arm64 Docker images? Check this post

In this post, I will provide a detailed guide on building FastDDS 3.6.0 on Ubuntu 22.04, with support for both amd64 and arm64 architectures. Let's get started.

① Install Docker and Docker buildx on Ubuntu 22.04.

② Prepare the source code for FastDDS 3.6.0 and its sub‑components: fastcdr, foonathan‑memory, statistics‑backend, and tinyxml2.

③ Based on the Dockerfile provided in the attachment, build the image with the following commands. You can add the --cache-to and --cache-from options to enable caching and avoid re‑downloading library dependencies.

For amd64:

docker buildx build \
 --platform linux/amd64 \
 -t fastdds-multiarch:3.6.0-amd64 \
 --load .

For arm64:

docker buildx build \
  --platform linux/arm64 \
  -t fastdds-multiarch:3.6.0-arm64 \
  --load .

④ After the above commands succeed, run docker images to verify that the images have been built successfully.

⑤ Run the container with the following command:

docker run -it --name fastdds-amd64 fastdds-multiarch:3.6.0-amd64

⑥ Under example/cpp/hello world, compile the sample using:

cmake .. -DCMAKE_PREFIX_PATH="/opt/fastdds3.6.0/install;/opt/fastdds3.6.0/thirdparty/install"
make

⑦ Finally, test data transmission and reception with:

./hello_world publisher
./hello_world subscriber
