Worked on the ros/rosdistro repository to deliver compatibility improvements for OpenCV and Qt6 on Ubuntu, focusing on future-proofing package management and dependency resolution. Addressed upstream packaging by updating rosdep rules and mappings, specifically adding Ubuntu resolute OpenCV rules and adjusting Qt6 t64 mappings to support evolving Ubuntu releases. Utilized YAML for configuration changes, ensuring that new mappings for libqt6gui6t64, libqt6opengl6t64, and libqt6widgets6t64 default to non-t64 packages while maintaining compatibility with existing focal and noble releases. This work enhanced build stability, reduced CI failures, and laid the foundation for broader cross-Ubuntu support in ongoing development.
