Worked on the ecmwf/eccodes repository to enhance build robustness by addressing a compilation issue related to the geography feature flag. Focused on ensuring that the codebase compiles reliably when the HAVE_GEOGRAPHY definition is absent, this work reduced the risk of build failures across different configurations. Applied expertise in C++ development, error handling, and conditional compilation to improve cross-platform portability and stability. The solution targeted conditional code paths, minimizing potential CI disruptions and supporting more flexible feature management. This contribution demonstrated a methodical approach to software compilation challenges, emphasizing maintainability and reliability in C/C++ projects with configurable build options.
