Worked on the zephyrproject-rtos/poky repository to improve build reliability for embedded Linux systems, focusing on stabilizing lttng-ust example builds. Addressed persistent build failures caused by undefined references when RPATH was stripped by implementing explicit library search paths and configuring rpath-link for both standard and CMake-based builds. This technical approach ensured proper linkage to required shared libraries, reducing CI flakiness and clarifying linker behavior for developers. Utilized C and Shell scripting within complex build systems, applying and backporting targeted patches to resolve cmake-multiple-shared-libraries errors. Demonstrated strong debugging and cross-compilation skills in a challenging embedded systems environment.
