PROFILE
Alexandre Bouvier
Over seven months, Amb worked on the shadps4-emu/shadPS4 repository, focusing on build system reliability, dependency management, and cross-platform consistency. Amb refactored the CMake-based build to unbundle libraries like libpng, zlib, and stb, migrating to system-provided or FetchContent-managed dependencies to reduce maintenance and improve reproducibility. They addressed critical build issues, such as SDL3_mixer linking and libusb discovery, and optimized the build by integrating system-installed libraries like CLI11 and Nlohmann JSON. Using C++, CMake, and Git, Amb’s contributions streamlined onboarding, improved CI feedback, and enhanced debugging workflows by fixing timestamp handling and ensuring accurate external dependency tracking.

Oct 1, 20252025-10 focused on stabilizing frame-dump time handling and delivering a targeted bug fix to improve timestamp accuracy in debugging workflows. The primary improvement addressed wrong local time retrieval and formatting in the Frame Dump Viewer and Save Data dialog, aligning behavior with the fmt library expectations (fmt 12). The work enhances data integrity for investigations and reduces user-facing timestamp anomalies, while maintaining a minimal, safe change footprint.

Mar 1, 2025Month: 2025-03 | Repository: shadps4-emu/shadPS4 | Summary: Focused on build-system reliability and dependency management. Implemented a LibUSB discovery fix and removed obsolete cryptopp configuration to simplify the build, improving cross-platform consistency and reducing maintenance overhead. Committed changes provide clearer discovery of system libraries and a leaner build surface, enabling faster CI feedback and easier onboarding for future contributors. Impact: More predictable builds, reduced risk of libusb/linking regressions, and a smaller, cleaner CMake configuration. This supports smoother developer workflows and quicker iteration on features. Technologies/skills demonstrated: CMake, FindPackage handling, custom Findlibusb module, dependency management, build-system refactoring, cross-platform compatibility.

Nov 1, 2024In 2024-11, completed a dependency management overhaul for shadPS4 by unbundling libpng and zlib and migrating to system-provided or FetchContent-distributed versions. This included removing the custom Findzlib-ng.cmake, updating CMakeLists to find and link PNG and ZLIB packages, and adding libpng as a subdirectory via FetchContent for zlib. These changes simplify dependencies, reduce maintenance overhead, and improve build reliability across environments. Commit: 5f4d03172f0a56aee48566164e030980a39c3a50 (cmake: unbundle libpng (#1576)).
