From 842685f0c3f38d81474e809ff0b112099ed11e1c Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Mon, 8 Sep 2014 13:49:36 +0200 Subject: [PATCH 1/2] Turn on -Werror=implicit-function-declaration GCC 4.4, the minimum compiler version, supports this option. Unlike other warnings, -Wimplicit-function-declaration warnings should be independent of compiler versions, so this change should not cause compiler-specific build failures. --- ChangeLog | 8 ++++++++ Makeconfig | 2 +- stdlib/tst-tls-atexit-lib.c | 2 ++ 3 files changed, 11 insertions(+), 1 deletion(-) 2014-09-08 Florian Weimer * Makeconfig (gccwarn-c): Turn implicit-function-declaration warnings into errors. * stdlib/tst-tls-atexit-lib.c: Include , for the __cxa_thread_atexit_impl prototype. diff --git a/Makeconfig b/Makeconfig index cef0f06..0f8069b 100644 --- a/Makeconfig +++ b/Makeconfig @@ -717,7 +717,7 @@ else +gccwarn := -Wall -Wwrite-strings -Winline endif +gccwarn += -Wundef -+gccwarn-c = -Wstrict-prototypes ++gccwarn-c = -Wstrict-prototypes -Werror=implicit-function-declaration # We do not depend on the address of constants in different files to be # actually different, so allow the compiler to merge them all. diff --git a/stdlib/tst-tls-atexit-lib.c b/stdlib/tst-tls-atexit-lib.c index 964f94b..b67d62f 100644 --- a/stdlib/tst-tls-atexit-lib.c +++ b/stdlib/tst-tls-atexit-lib.c @@ -16,6 +16,8 @@ License along with the GNU C Library; if not, see . */ +#include + extern void *__dso_handle; typedef struct -- 1.9.3
