Subject: pgsql: Suppress "has no symbols" linker warnings on macOS.
Date: Wed, 29 Apr 2026 17:29:40 +0000
Message-ID: <E1wI8jE-003MML-0W@gemulon.postgresql.org> (raw)
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.
Per project policy, this is a candidate for back-patching into
out-of-support branches: it suppresses annoying compiler warnings
but changes no behavior.
