Worked on improving build-system stability for the pytorch/executorch repository by addressing a critical dependency issue. Focused on CMake and dependency management, the developer identified and resolved a missing etdump dependency required by the executor runner, ensuring the toolchain was complete for both execution and debugging tasks. This fix reduced CI and build failures, streamlining local development and enhancing reliability across environments. The work involved validating the updated build path to prevent future tool-related issues and clarifying build configurations. Leveraging skills in C++ and Python, the developer strengthened the foundation for smoother integrations and more robust end-to-end workflows in the project.
