编译内核模块(错误阶段2,MODPOST 0)

标签: linux makefile module kernel

我试图在Arch Linux上编译示例内核模块(test.c),只需在带有source和Makefile的目录中键入 make

它将创建一个空文件夹 .tmp_versions 和一个空文件 Module.symvers modules.order ,但没有一个 .ko

我也尝试使用Ubuntu在虚拟机下编译它,但输出却完全相同。样本来自互联网(2个)。

我还应该做些什么来编译它?

Makefile:

obj−m += test.o
default:
 $(MAKE) -C /lib/modules/$(shell uname -r)/build SUBDIRS=$(PWD) modules
clean:
 $(MAKE) -C $(KDIR) M=$(PWD) clean

但这显示了我

make -C /lib/modules/4.18.14-arch1-1-ARCH/build SUBDIRS=/home/hime/Documents/module modules
make[1]: Entering directory '/usr/lib/modules/4.18.14-arch1-1-ARCH/build'
Building modules, stage 2.
MODPOST 0 modules
make[1]: Leaving directory '/usr/lib/modules/4.18.14-arch1-1-ARCH/build'

或(详细):

make    -C  "/lib/modules/4.18.14-arch1-1-ARCH/build"   SUBDIRS="/home/hime/Documents/module"   modules V=1
make[1]: Entering directory '/usr/lib/modules/4.18.14-arch1-1-ARCH/build'

echo >&2 "         Run 'make oldconfig && make prepare' on kernel src to fix it.";  \

mkdir -p /home/hime/Documents/module/.tmp_versions ; rm -f /home/hime/Documents/module/.tmp_versions/*
