Worked on the luanti-org/luanti repository to enhance the stability and portability of the codebase, focusing on improving compile-time behavior in C++. Addressed a compatibility issue by making SColor comparison operators constexpr, enabling their use in constant expressions and ensuring support for older GCC versions such as 7.5.0. This change reduced compile-time errors and improved the reliability of library builds across different environments. The work involved careful refinement of library code to maintain correctness while expanding compiler compatibility. Utilized C++ and library development skills to deliver a targeted bug fix, prioritizing robust cross-platform support and maintainable code practices.
