POSIX/SITL builds on macOS produce two classes of benign warnings that clutter output and obscure real issues: ranlib: warning: 'lib*.a(foo.o)' has no symbols ld: warning: ignoring duplicate libraries: ... The ranlib warnings come from sources wrapped in #if defined(CONFIG_*) guards (i2c.cpp, spi.cpp, board_common.c, pab_manifest.c, px4_log_history.cpp) and dummy.cpp placeholders, which legitimately compile to empty object files on POSIX. GNU ranlib ignores this; Apple's warns. The warning is emitted by 'ar qc' (which implicitly builds a symbol table), not by ranlib itself, so overriding only ARCHIVE_FINISH is insufficient. Use 'ar qcS' to skip the implicit symbol table, then let ranlib -no_warning_for_no_symbols build it quietly via ARCHIVE_FINISH. The duplicate-library warnings come from CMake intentionally re-emitting static libraries on the link line to resolve circular dependencies between px4_layer, px4_work_queue, px4_daemon and lockstep_scheduler. GNU ld silently dedupes; Apple's ld-prime (Xcode 15+) warns. Pass -no_warn_duplicate_libraries to the linker. Both fixes are Darwin-only and have no effect on Linux CI or NuttX builds.
