Makefile for a single source file
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 ?)

Hi, No. This is a newbie question, and I believe this is the right mailing list to get help.

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 ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies

Regards, Kevin Have you tested it? Test exactly what you are asking and see what happens. That's the best way to learn.
