Buster's linker defaults to RUNPATH, which is searched after LD_LIBRARY_PATH. The TV's LD_LIBRARY_PATH includes /usr/lib which has the system SDL2 (without remote control input support). With RPATH, $ORIGIN/lib is searched first, loading the SDL-webOS community fork that handles Magic Remote D-pad key events. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
