During February 2025, work focused on improving the aseprite/libpng repository by addressing cross-compilation challenges on Apple platforms. The developer enhanced the CMake-based build system, specifically by importing the APPLE variable into genout.cmake.in to ensure consistent platform-specific logic between host and target environments. This adjustment resolved a persistent issue where cross-building for Apple targets would fail due to inconsistent variable handling. By concentrating on build systems and cross-compilation, and leveraging CMake as the primary language and tool, the developer improved build reliability across platforms. The work addressed one critical bug, contributing to more stable and predictable cross-platform development workflows.
