编译内核驱动模块出错（./arch/x86/include/asm/xxx fatal error: asm/xxx: No such file or directory）

今天编译驱动时突然出现以下错误信息，后面经检查是因为我更换了之前的内核源码导致的。

以下是编译错误输出信息:

解决办法

修改内核源码Makefile文件

我个人是不推荐这样做的，因为之前图方便就直接修改了内核源码根目录下的Makefile文件，导致时间久了忘记这回事，今天突然更换内核源码后就报错了。

修改方法

打开内核源码根目录下的Makefile，定位到如下位置:

ARCH		    ?= $(SUBARCH)
CROSS_COMPILE	?= $(CONFIG_CROSS_COMPILE:"%"=%)

修改为:

ARCH		    ?= arm
CROSS_COMPILE	?= arm-linux-gnueabihf-

上述位置的arm/arm-linux-gnueabihf-取决你你自己使用的架构和交叉编译工具

修改驱动程序工程下的Makefile文件(推荐)

假如你的Makefile如下:

KERNELDIR := /mnt/hgfs/Ubuntu/ebf_6ull_linux
CURRENT_PATH := $(shell pwd)
obj-m := xxx.o

build: kernel_modules

kernel_modules:
	$(MAKE) -C $(KERNELDIR) M=$(CURRENT_PATH) modules
clean:
	$(MAKE) -C $(KERNELDIR) M=$(CURRENT_PATH) clean

请添加两个编译变量在make命令后方

KERNELDIR := /mnt/hgfs/Ubuntu/ebf_6ull_linux
CURRENT_PATH := $(shell pwd)
ENV:=ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-
obj-m := xxx.o

build: kernel_modules

kernel_modules:
	$(MAKE) $(ENV) -C $(KERNELDIR) M=$(CURRENT_PATH) modules
clean:
	$(MAKE) $(ENV) -C $(KERNELDIR) M=$(CURRENT_PATH) clean

这样的话无论内核源码如何替换都不会影响驱动程序的正常编译

悦读

道可道，非常道；名可名，非常名。 无名，天地之始，有名，万物之母。 故常无欲，以观其妙，常有欲，以观其徼。 此两者，同出而异名，同谓之玄，玄之又玄，众妙之门。
