Worked on integrating VkDCT v1.3.4 into the JuliaPackaging/Yggdrasil repository, focusing on enhancing CUDA build reliability and compatibility. Addressed critical build blockers by implementing a new CUDA build recipe, resolving issues such as missing nvcc and vkFFT.h files, log2 ambiguities, and linker errors. Improved packaging maintainability by restructuring patches and adopting Yggdrasil’s DirectorySource and atomic_patch conventions. Capped CUDA support at version 12, fixed audit issues with libcuda.so.1, and updated Julia compatibility to v1.10. Utilized C++, Julia, and GPU programming expertise to deliver more reliable CI builds and broader CUDA-enabled deployment for downstream users.
