为RPI

Question

我试图编译一个＆＃34; Hello Word＆＃34;使用Raspberry Pi2的内核模块。我安装了rpi-source。

这是我正在使用的Makefile：

obj-m += hello.o

all:
    make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules

clean:
    make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean

但我没有收到hello.ko文件。这是我的结果：

make -C /lib/modules/4.4.7-v7+/build M= modules
make[1]: Entering directory '/home/pi/linux-cd560b8658868d9652ab31754e02f86daf6831ba'

你能帮助我吗？
