From 9b6e2c363f2686d6f7bf61fbe58b7591b71d3e8b Mon Sep 17 00:00:00 2001 From: Masahiro Yamada <yamada.m@jp.panasonic.com> Date: Fri, 28 Feb 2014 14:33:30 +0900 Subject: [PATCH] kbuild: fix CROSS_COMPILE settings in config.mk The syntax CROSS_COMIPLE ?= <cross_compiler_prefix> does not work because config.mk is parsed after exporting CROSS_COMPILE. Like Linux Kernel's arch/$(ARCH)/Makefile, we must write as follows: ifeq ($(CROSS_COMPILE),) CROSS_COMPILE := <cross_compiler_prefix> endif Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> --- arch/arc/config.mk | 8 ++++++-- arch/arm/config.mk | 4 +++- arch/avr32/config.mk | 5 ++++- arch/blackfin/config.mk | 4 +++- arch/m68k/config.mk | 4 +++- arch/microblaze/config.mk | 4 +++- arch/mips/config.mk | 4 +++- arch/nds32/config.mk | 4 +++- arch/nios2/config.mk | 4 +++- arch/openrisc/config.mk | 4 +++- arch/powerpc/config.mk | 4 +++- arch/sh/config.mk | 4 +++- arch/sparc/config.mk | 4 +++- 13 files changed, 43 insertions(+), 14 deletions(-) diff --git a/arch/arc/config.mk b/arch/arc/config.mk index 76f4f7c0dd..d9f5d9d787 100644 --- a/arch/arc/config.mk +++ b/arch/arc/config.mk @@ -9,14 +9,18 @@ CONFIG_SYS_LITTLE_ENDIAN = 1 endif ifdef CONFIG_SYS_LITTLE_ENDIAN -CROSS_COMPILE ?= arc-buildroot-linux-uclibc- +ARC_CROSS_COMPILE := arc-buildroot-linux-uclibc- endif ifdef CONFIG_SYS_BIG_ENDIAN -CROSS_COMPILE ?= arceb-buildroot-linux-uclibc- +ARC_CROSS_COMPILE := arceb-buildroot-linux-uclibc- PLATFORM_LDFLAGS += -EB endif +ifeq ($(CROSS_COMPILE),) +CROSS_COMPILE := $(ARC_CROSS_COMPILE) +endif + PLATFORM_CPPFLAGS += -ffixed-r25 -D__ARC__ -DCONFIG_ARC -gdwarf-2 LDSCRIPT := $(SRCTREE)/$(CPUDIR)/u-boot.lds diff --git a/arch/arm/config.mk b/arch/arm/config.mk index 1db80be354..792cb43450 100644 --- a/arch/arm/config.mk +++ b/arch/arm/config.mk @@ -5,7 +5,9 @@ #
