From 80a45458e0d9b75d508110bd880d0ae0432b0356 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Thu, 25 Oct 2012 14:52:12 -0400 Subject: [PATCH] configure: test not just compiling but linking with -march/-mtune pcc wrongly passes any option beginning with -m to the linker, and will break at link time if these options were added to CFLAGS. testing linking lets us catch this at configure time and skip them. --- configure | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/configure b/configure index c1bcac7c..327734ae 100755 --- a/configure +++ b/configure @@ -269,8 +269,8 @@ tryflag CFLAGS_AUTO -falign-jumps=1 # work anyway (issues with atomic ops). # if test "$ARCH" = "i386" ; then -fnmatch '-march=*|*\ -march=*' "$CFLAGS" || tryflag CFLAGS_AUTO -march=i486 -fnmatch '-mtune=*|*\ -mtune=*' "$CFLAGS" || tryflag CFLAGS_AUTO -mtune=generic +fnmatch '-march=*|*\ -march=*' "$CFLAGS" || tryldflag CFLAGS_AUTO -march=i486 +fnmatch '-mtune=*|*\ -mtune=*' "$CFLAGS" || tryldflag CFLAGS_AUTO -mtune=generic fi if test "x$warnings" = xyes ; then -- 2.20.1
