Worked on the DragonBluep/openwrt repository to enhance build system reliability by implementing global linker options for hostapd CLI tools. Focused on Makefile engineering, the approach involved aligning TARGET_LDFLAGS_C with TARGET_LDFLAGS, ensuring that hostapd_cli and wpa_cli consistently received the intended linker flags during cross-compilation. This adjustment reduced linker-related build failures and improved the stability of CLI tool deployment across OpenWrt environments. The work demonstrated skills in build system configuration and linker options management, specifically using Makefile. No major bugs were addressed during this period, with efforts concentrated on feature development and improving downstream maintainability for hostapd tooling.
