From 906d95695af95970bf551ea55b6c3e70332c6b97 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Tue, 22 Nov 2016 05:22:32 +0000 Subject: [PATCH] disable varargs warning on clang The issue is that 'len' is an unsigned char and we violate the promotion rules for passing the value to va_start. passing an object that undergoes defau lt argument promotion to 'va_start' has undefined behavior [-Wvarargs] | va_start(ap, len); Signed-off-by: Khem Raj --- Makefile | 1 + 1 file changed, 1 insertion(+) diff --git a/Makefile b/Makefile index 8c5e380..f41ef1a 100644 --- a/Makefile +++ b/Makefile @@ -53,6 +53,7 @@ ifeq ($(COMPILER), clang) CFLAGS += -Wno-microsoft -Qunused-arguments -Wno-unused-function CFLAGS += -Wno-unused-value -Wno-tautological-constant-out-of-range-compare CFLAGS += -Wno-parentheses-equality -Wno-incompatible-pointer-types +CFLAGS += -Wno-error=varargs endif ifeq ($(CONFIG_LIBFFMPEG_STATIC),yes) -- 1.9.1
