From 06c5040cdb13d27adad118f2fbfae905a1911b37 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Mon, 15 Oct 2007 22:17:25 +0200 Subject: kbuild: enable 'make CPPFLAGS=...' to add additional options to CPP The variable CPPFLAGS is a wellknown variable and the usage by kbuild may result in unexpected behaviour. This patch replace use of CPPFLAGS with KBUILD_CPPFLAGS all over the tree and enabling one to use: make CPPFLAGS=... to specify additional CPP commandline options. Patch was tested on following architectures: alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k, s390 Signed-off-by: Sam Ravnborg --- arch/um/Makefile-x86_64 | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch/um/Makefile-x86_64') diff --git a/arch/um/Makefile-x86_64 b/arch/um/Makefile-x86_64 index 8836f0df36a..bcfd6ea3003 100644 --- a/arch/um/Makefile-x86_64 +++ b/arch/um/Makefile-x86_64 @@ -14,7 +14,7 @@ KBUILD_CFLAGS += $(_extra_flags_) CHECKFLAGS += -m64 KBUILD_AFLAGS += -m64 LDFLAGS += -m elf_x86_64 -CPPFLAGS += -m64 +KBUILD_CPPFLAGS += -m64 ELF_ARCH := i386:x86-64 ELF_FORMAT := elf64-x86-64 -- cgit v1.2.3
