编译spidev_test程序


spidev_test测试程序位于kernel/linux-3.10.y/Documentation/spi目录下，在编译时需要先修改Makefile文件成如下：

# List of programs to build

hostprogs-y := can_test

# Tell kbuild to always build the programs

always := $(hostprogs-y)

HOSTCFLAGS_spidev_test.o += -I$(objtree)/usr/include

然后再添加Android.mk文件

# Copyright 2006 The Android Open Source Project

LOCAL_PATH:= $(call my-dir)

include $(CLEAR_VARS)

LOCAL_SRC_FILES += can_test.c

LOCAL_MODULE:= can_test

include $(BUILD_EXECUTABLE)

最后使用mm命令编译成可执行程序，push到system/bin下执行。
