Cross compiling a kernel module

Question

I\'m trying to cross compile a helloworld kernel (2.6.x) module for ARM architecture on my intel x86 host.

The codesourcery tool chain for ARM is located at: /ho

Answer 1

MODULES := hola_kern.o

#guest architecture
ARCH := arm

CROSS_COMPILE := arm-linux-gnueabi-
obj-m := $(MODULES)

#path of the arm compiled kernel
ROOTDIR := /home/aldo/c/proyectos/prefixa/work/kernels/linux-omap-5f0a6e2

MAKEARCH := $(MAKE) ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE)

all: modules
modules:
    $(MAKEARCH) -C $(ROOTDIR) M=${shell pwd} modules

clean:
    $(MAKEARCH) -C $(ROOTDIR) M=${shell pwd} clean
