Question

我正在使用一个小的演示内核模块学习内核中断使用这两个标题包括

ASM / exception.h
ASM /马赫/ irq.h

我的Makefile是

ifeq (${KERNELRELEASE},)

    KERNEL_SOURCE := /lib/modules/$(shell uname -r)/build

    PWD := $(shell pwd)


default:
    make    -C ${KERNEL_SOURCE} SUBDIRS=${PWD} modules 

clean:
    make    -C ${KERNEL_SOURCE} SUBDIRS=${PWD} clean



else

obj-m := irq_demo.o

endif

我得到的错误

irq_demo.c:9:27: fatal error: asm/exception.h: No such file or directory
 #include <asm/exception.h>

我在/usr/src/linux-headers-3.16.0-30-generic/arch/arm/include /

的系统中找到了asm / exception.h

[1]但如何在Makefile中包含此路径
[2] /usr/src/linux-headers-3.16.0-30-generic/include/asm-generic/与arch / arm / include / asm /？相关联？如果是，那么如何？

首先尝试在make之后添加ARCH = arm 即

make ARCH=arm -C ${KERNEL_SOURCE} SUBDIRS=${PWD} modules

============================= OR ================= ============

你可以尝试在make之前添加行吗

CARGS = -I /lib/modules/$(shell uname -r)/arch/arm/include/
make  $(CARGS) -C ${KERNEL_SOURCE} SUBDIRS=${PWD} modules

如何在内核模块Makefile中提供include目录路径
