I write a simple test file, mymodule.c. Makefile as below
########################
obj-m := mymodule.o
all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
##########################
[root@localhost hello]# make
make -C /lib/modules/2.6.8.1-12mdk/build M=/home/yipiao/programing linux/code/chapter18/hello modules
make[1]: Entering directory `/usr/src/linux-2.6.8.1-12mdk'
make[1]: *** No rule to make target `linux/code/chapter18/hello'. Stop.
make[1]: Leaving directory `/usr/src/linux-2.6.8.1-12mdk'
make: *** [all] Error 2

what is the problem?

hi,
why r u using modules last word in make command??
try
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) in makefile

The Makefile that works for me is...

1 ifneq ($(KERNELRELEASE),)
2 obj-m :=driver.o
3 else
4 KERNELDIR ?= /lib/modules/$(shell uname -r)/build
5 PWD:=$(shell pwd)
6 default:
7 $(MAKE) -C $(KERNELDIR) M=$(PWD) modules
8 endif
9
10 clean:
11 rm -rf *.ko
12 rm -rf *.o
13 rm -rf *.mod.c


P.S. I am using Kernel Version 2.6

hi,
yes its working Makefile without linenos

i have settled the problem, the Makefile is all right if the directory does not include space. the space in the directory "programing linux" makes the mess.i changed the directory name, then it is working now...

thank you all
