Mar 1, 2026During March 2026, I delivered a set of cross-platform, build-system, and tooling improvements for Drake (RobotLocomotion/drake) that enhance stability, portability, and release velocity. Key efforts included upgrading the Python environment to 3.12 with synchronized tooling, modernizing the CMake/Bazel build configurations across macOS, Alma Linux, and Ubuntu Noble; aligning compilers/toolchains (including GCC 14 support and a 3.28+ minimum for CMake); and improving documentation alignment for build tooling. CI/CD reliability was enhanced by standardizing build inputs and adding S3-based release artifact mirroring to streamline releases. A developer-experience improvement introduced a wrapper configuration for Bazel debug builds to extend test timeouts and simplify debugging. Finally, I fixed a critical Apple Clang 21 compatibility issue in the Warn class initialization to support temporary std::string_view inputs. Collectively, these changes improve platform parity, reproducibility, and release confidence, while enabling teams to adopt newer toolchains with less friction.
