Is this part of the Eudyptula Challenge? On 13 Sep 2014 16:35, "Kevin Wilson" <wkevils@gmail.com> wrote:

Hi, I have a single source file which I wrote, implementing a kernel module: helloworld.c

In order to built it, I prepared the following Makefile:

obj-m += helloworld.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

Is it ok ? or should the obj-m parameter be *different* than the the source file (without the *.o suffix) (something like obj-m += hello.o ?)

Regards, Kevin

Does the above work for you? Have you read the kernel documentation about how to write stand-alone Makefiles? It should answer this question for you, right? thanks, greg k-h
