linux - fatal error asm/bitsperlong.h 没有这样的文件或目录

Question

我尝试在 Ubuntu 14.04 上构建 Linux 模块。

但出现如下错误。

dhkim@eslee:~/Project/Linux/Hello$ make
make -C /lib/modules/3.13.0-106-generic/build M=/home/dhkim/Project/Linux/Hello modules
make[1]: Entering directory `/usr/src/linux-headers-3.13.0-106-generic'
  CC [M]  /home/dhkim/Project/Linux/Hello/hello.o

include/uapi/asm-generic/int-ll64.h:11:29: fatal error: asm/bitsperlong.h: No such file or directory
 #include <asm/bitsperlong.h>

compilation terminated.
make[2]: *** [/home/dhkim/Project/Linux/Hello/hello.o] error 1
make[1]: *** [_module_/home/dhkim/Project/Linux/Hello] error 2
make[1]: Leaving directory `/usr/src/linux-headers-3.13.0-106-generic'
make: *** [default] error 2

构建环境如下。

obj-m := hello.o
KDIR := /lib/modules/$(shell uname -r)/build
PWD := $(shell pwd)

default :
    $(MAKE) -C $(KDIR) M=$(PWD) modules

clean :
    rm -rf *.ko *.mod.* *.o

如何解决这个问题？

我注意到错误路径中出现了“arm”一词。在将系统设置为 ARM 交叉编译后，我遇到了相同的错误。如果您尝试构建普通的 x86 模块，您至少需要暂时恢复各种环境变量。

export CROSS_COMPILE=
export ARCH=x86_64 [or whatever arch you have]
