Thanks Xiangfei,
I am referring to the exactly the same kernel which i
am running.
but i am getting this output, if you compare to the
output given by you, i am not getting CC and LD lines
(which means it is not compiling the module)
Any idea what is the problem ?
make -C
/lib/modules/2.6.5-7.162-bigsmpAnvoraKprobe/build
M=/local/oracle/try modules
make[1]: Entering directory
`/local/oracle/linux-2.6.5-7.162'
Building modules, stage 2.
MODPOST
make[1]: Leaving directory
`/local/oracle/linux-2.6.5-7.162'
Here is my makefile:
# If KERNELRELEASE is defined, we've been invoked from
the
# kernel build system and can use its language.
ifneq ($(KERNELRELEASE),)
obj-m := hello.o
# Otherwise we were called directly from the command
# line; invoke the kernel build system.
else
KERNELDIR ?= /lib/modules/$(shell uname
-r)/build
PWD := $(shell pwd)
default:
$(MAKE) -C $(KERNELDIR) M=$(PWD) modules
endif
