Worked on stabilizing build processes for the libsdl-org/libavif repository, focusing on improving compatibility across ARM toolchains. Addressed a critical build issue by patching the libyuv integration to support GCC 10 on ARM, updating CMakeLists and refining ARM-specific compiler flags to align with newer toolchains. This targeted fix reduced build failures in continuous integration and release pipelines, enhancing downstream portability for ARM environments. The work relied on expertise in build systems, cmake, and cross-compilation, utilizing both bash and cmake to ensure robust and reliable builds. The approach emphasized maintainability and compatibility for developers relying on ARM/gcc-10 builds.
