From: Isaku Yamahata Subject: [PATCH] use HOSTCC to determine HOSTCFLAGS Date: Wed, 14 Dec 2005 16:38:04 +0900 Message-ID: <20051214073804.GD12134@valinux.co.jp> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Return-path: Content-Disposition: inline List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Sender: xen-devel-bounces@lists.xensource.com Errors-To: xen-devel-bounces@lists.xensource.com To: xen-devel@lists.xensource.com List-Id: xen-devel@lists.xenproject.org Hi. HOSTCC should be used to set HOSTCFLAGS instead of CC. There is a case where HOSTCC doesn't accept -Wdeclaration-after-statement, while CC does. It results in a compilation error. This patch fixes it Signed-off-by: Isaku Yamahata -- diff -r 94cb428d363d -r 164e8408c67a Config.mk --- a/Config.mk Mon Dec 12 15:20:51 2005 +0900 +++ b/Config.mk Mon Dec 12 17:36:35 2005 +0900 @@ -38,10 +38,10 @@ EXTRA_LIB += $(EXTRA_PREFIX)/$(LIBDIR) endif -test-gcc-flag = $(shell $(CC) -v --help 2>&1 | grep -q " $(1) " && echo $(1)) +test-gcc-flag = $(shell $(1) -v --help 2>&1 | grep -q " $(2) " && echo $(2)) -HOSTCFLAGS += $(call test-gcc-flag,-Wdeclaration-after-statement) -CFLAGS += $(call test-gcc-flag,-Wdeclaration-after-statement) +HOSTCFLAGS += $(call test-gcc-flag,$(HOSTCC),-Wdeclaration-after-statement) +CFLAGS += $(call test-gcc-flag,$(CC),-Wdeclaration-after-statement) LDFLAGS += $(foreach i, $(EXTRA_LIB), -L$(i)) CFLAGS += $(foreach i, $(EXTRA_INCLUDES), -I$(i)) -- yamahata
