From 0da02415a578512570aaee6598e1dfc07ce42e4d Mon Sep 17 00:00:00 2001 From: Rainer Jung Date: Mon, 16 Oct 2017 09:22:38 +0000 Subject: [PATCH] Fix maintainer mode with GCC/Clang. Setting -Wstrict-prototypes in combination with -Werror leads to compiler errors during configure checks (autoconf generates incomplete prototypes). Adding -Wno-error=strict-prototypes lets the compiler tolerate those. Possible future enhancement: remember such "configure time only" flags and remove them from CFLAGS before generating our build time files (Makefile, config_vars.mk etc.), so that the full -Werror is in place during building. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1812263 13f79535-47bb-0310-9956-ffa450edef68 --- configure.in | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/configure.in b/configure.in index ef7bd02482..2f328cc2a8 100644 --- a/configure.in +++ b/configure.in @@ -630,6 +630,10 @@ AC_ARG_ENABLE(maintainer-mode,APACHE_HELP_STRING(--enable-maintainer-mode,Turn o APR_ADDTO(CPPFLAGS, -DAP_DEBUG) if test "$GCC" = "yes"; then APR_ADDTO(CFLAGS,[-Wall -Wmissing-prototypes -Wstrict-prototypes -Wmissing-declarations -Wpointer-arith]) + # Next flag needed, because -Wstrict-prototypes in combination with + # -Werror leads to compiler errors during configure checks (autoconf + # generates incomplete prototypes). + APACHE_ADD_GCC_CFLAG([-Wno-error=strict-prototypes]) APACHE_ADD_GCC_CFLAG([-std=c89]) APACHE_ADD_GCC_CFLAG([-Werror]) APACHE_ADD_GCC_CFLAG([-Wdeclaration-after-statement]) -- 2.40.0
