From a563e891c72d47a9ed4aa840877214075963f4aa Mon Sep 17 00:00:00 2001 From: Nathan Bossart Date: Tue, 28 Apr 2026 15:27:39 -0500 Subject: [PATCH v4 1/1] Suppress "has no symbols" linker warnings on macOS. After a recent macOS update, building Postgres produces warnings that look like this: ranlib: warning: 'libpgport_shlib.a(pg_cpu_x86.c.o)' has no symbols ranlib: warning: 'libpgport_shlib.a(pg_popcount_x86.c.o)' has no symbols To fix, add a dummy symbol to files that may otherwise have none.
