From 6ea6ed74188f2438707536548aaf8a35a96b484c Mon Sep 17 00:00:00 2001 From: Willy Tarreau Date: Mon, 11 Apr 2022 16:31:31 +0200 Subject: [PATCH] BUILD: makefile: silence unbearable OpenSSL deprecation warnings OpenSSL 3.0 emits tons of deprecation warnings for the engine API, and it becomes a real problem because these hide other real warnings and will prevent distros from building with -Werror. Fortunately there's a macro to shut this one, OPENSSL_SUPPRESS_DEPRECATED, that is sufficient to get things back to normal, so let's define it when USE_ENGINE is set. This way we still get a chance to see other deprecation warnings when engines are not used. --- Makefile | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/Makefile b/Makefile index fc0ae67ba..026e334c6 100644 --- a/Makefile +++ b/Makefile @@ -623,6 +623,15 @@ OPTIONS_LDFLAGS += -ldl endif OPTIONS_OBJS += src/ssl_sample.o src/ssl_sock.o src/ssl_crtlist.o src/ssl_ckch.o src/ssl_utils.o src/cfgparse-ssl.o src/jwt.o endif + +ifneq ($(USE_ENGINE),) +# OpenSSL 3.0 emits loud deprecation warnings by default when building with +# engine support, and this option is made to silence them.
