内核模块Makefile为什么不能识别目录中的任何文件？

编程问答 2022-06-10

问题描述

我刚刚开始从事内核模块编程的工作，而我很难使makefile正确编译c文件。我正在使用manjaro 5.4

当我在与代码和此Makefile相同的目录中执行make时：

obj-m += hello1.o

PATH = /usr/lib/modules/$(shell uname -r)/build

all:
    $(MAKE) -C $(PATH) M=$(PWD) modules

clean:
    $(MAKE) -C $(PATH) M=$(PWD) clean

我得到了

的输出 
make -C /usr/lib/modules/5.4.67-1-manjaro/build M=/home/aidan/Documents/kernelProgramming/hw2 modules
make: make: No such file or directory
make: *** [Makefile:7: all] Error 127

我已检查是否已安装所有正确的标题

路径/usr/lib/modules/5.4.67-1-manjaro/build如下所示：

$ ls
arch   crypto   include  kernel    mm              samples   sound  virt
block  drivers  init     lib       Module.symvers  scripts   tools
certs  fs       Kconfig  Makefile  net             security  usr

我很沮丧，我找不到导致该错误的原因。
