Hey think it is a really god idea to write about common mistakes in
kernel codes.  I have one , I realize  that when you just copy and
paste the code for the makefiles from the Internet or PDF's it doesn't
compile the first time, you have to eliminate some tabs spaces  first;
for example in the The Linux Kernel Module Programming Guide there is
a simple hello-1.c and its makefile is .

obj-m += hello-1.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

when you run make in the terminal

make[1]: *** No rule to make target `-C'.  Stop.

Could appear

you have to copy in plain text or type yourself. well it is not a real
kenrel problem but mya help to others i realize it happens the first
time I compiled my "simplest module"

Thanks

Victor
