building a out-of-tree module on Beagle Bone Black - module

Question

Machine Details :
Linux beaglebone 3.8.13-bone47 armv7l GNU/Linux
Problem Details:
In a attempt to write out-of-tree modules on beagle bone black(as intree modules require me to compile/flash them again and again ), i have logged in to beagle bone black revc through ssh client, which gives me a command line interface via putty, as in general out-of-tree module development, i have tried to compile module with the following make file
ifneq ($(KERNELRELEASE),)
# kbuild part of makefile
obj-m := module.o
#module-objs := module.o
else
# normal makefile
KDIR ?= /lib/modules/$(shell uname -r)/build
PWD := $(shell pwd)
default:
$(MAKE) -C $(KDIR) M=$(PWD) modules
endif
resulting an error
root#beaglebone:~/lddgeek# make
make -C /lib/modules/3.8.13-bone47/build M=/root/lddgeek modules
make: *** /lib/modules/3.8.13-bone47/build: No such file or directory. Stop.
make: *** [default] Error 2
but when i parse to the path of KDIR i did not find build folder as we find it in an normal ubuntu installed on x86
if i have to develop drivers/modules out-of-tree on a Beagle how could i do that?

Answer 1

The reason i was not able to compile was i was missing the kbuild environment , i need to install kernel headers which will give me the capability to compile out-of-tree/external modules
#wget https://raw.github.com/gkaindl/beaglebone-ubuntu-scripts/master/bb-get-rcn-kernel-source.sh
#chmod +x bb-get-rcn-kernel-source.sh
#./bb-get-rcn-kernel-source.sh
The above steps actually helped me in solving the errors faced , while i was able to insert,remove the hello world module that i was trying to build
