During May 2025, work focused on developing a new official manylinux_2_38 Docker image with LLVM 15 for the Loongson-Cloud-Community/docker-library repository. This involved creating a Dockerfile-based build environment tailored for cross-architecture development, integrating tools such as Ninja and supporting LLVM compilation for LoongArch. A Makefile was implemented to automate building and publishing the image, establishing a reproducible and scalable CI baseline. The solution streamlined CI and build environments for Loongson projects, reducing setup time for developers. Technical skills applied included Docker, Linux, and build systems, with all tooling and documentation designed to simplify integration into existing CI workflows.
