May 2026: Stabilized dde-shell builds against Qt 6.10+ by fixing a missing CMake target. Added QuickTemplates2Private to Qt private components to resolve the target error, enabling successful builds in development and CI for Qt 6.10+.

February 2026 performance focused on stability and cross-version compatibility in key Deepin desktop components. In linuxdeepin/dde-file-manager, I resolved a C++15 template deduction build break by removing static Q_DECLARE_METATYPE declarations from headers and moving meta-type registration to runtime, enabling compilation with complex nested types (commit 4e20c78324af277ae9f97bcd164a933e79578bff). In linuxdeepin/dtkwidget, I fixed DTabBar compatibility for Qt 6.10.2 by updating tab button positioning to rely on dragOffset for Qt 6.10.2+ while preserving behavior for older versions (commit 561141f750344f6713b7d2d022bb5d24585a29aa). These changes improve cross-version stability, reduce maintenance burden, and ensure consistent UI behavior across Qt versions.

December 2025: Maintained build health for dde-control-center by implementing a Qt 6.10+ compatibility fix. This work ensures the project builds reliably on Qt 6.10 and newer, reducing CI/build interruptions and enabling smoother releases. The change adds an explicit Qt6QuickPrivate requirement in CMakeLists to align with Qt6 Quick Private API changes, addressing compatibility gaps and future-proofing the build.

October 2025 — LinuxDeepin DDE File Manager: Qt 6.10 Build Compatibility Fix. Implemented essential build-system updates to support Qt 6.10+, ensuring correct locating and linking of GUI and Widget private headers. This reduces breakages with newer Qt versions and improves downstream packaging readiness.

June 2025 monthly summary: Implemented GCC 15 compatibility fixes across linuxdeepin/dde-file-manager and linuxdeepin/dde-daemon, improving build reliability and runtime stability on newer compilers. Key changes include a header fix to resolve GCC 15 build failures and an update to timer callback signatures to satisfy stricter function pointer checks, with no runtime behavior changes. Commits included: baa88b600c4398bc49c36a3547077cd8d3a4e5cf (fix: fix build on gcc 15) and 582054f3cb14902dcf96ae6e80b1b18a22187e23 (fix: Fix incompatible function pointer types with g_timeout_add_full on GCC 15).

May 2025 monthly summary for linuxdeepin/dde-file-manager: Delivered key enhancements including a PCRE1-to-PCRE2 migration for regex handling and build stabilization by addressing missing library links in CMake. These changes improve compatibility with modern systems, reduce build-time failures, and support future maintenance and packaging. Commits reflecting the work are 682dffd359abdf42329f03a1cb0ca666eb3a328d and ece85c14c49fd48b825c0ae9fa8469a5167a27dd.
