During November 2025, Smiling Poplar focused on resolving critical build issues for the ggml and llama.cpp repositories, targeting macOS 11 compatibility. By identifying missing mathematical function support, they addressed compilation failures by including the cmath header, a solution that required careful attention to platform-specific toolchain behavior on Apple clang. Their work in C++ and macOS development improved build stability and reduced friction for developers working across both projects. Although the scope was limited to bug fixes rather than new features, the changes enhanced cross-platform maintainability and ensured that release workflows for macOS users remained reliable and free from build blockers.
