hello_module.ko with linux2.6.38 gcc and arm-linux-gcc

環境 ubuntu 11.04kernel : 2.6.38-8-generic

專案開發工具: kscope

hello_c_code:

製作 Makefile

#CC= $(CROSS_COMPILE)gcc

#CROSS_COMPILE ?=~/toolschain/4.5.1/bin/arm-linux-

#EXTRA_CFLAGS += -I$(KERNELDIR)/include

ifneq ($(KERNELRELEASE),)

# call from kernel build system

#~/ARM/toolschain/4.5.1/bin

obj-m := hello.o

#/lib/modules/$(shell uname -r)/build

#~/linux-2.6.38

else

#KERNELDIR := ~/linux-2.6.38

KERNELDIR := /lib/modules/$(shell uname -r)/build

PWD := $(shell pwd)

modules:

#$(MAKE) -C $(KERNELDIR) M=$(PWD) ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) modules

$(MAKE) -C $(KERNELDIR) M=$(PWD) modules

modules_install:

# $(MAKE) -C $(KERNELDIR) M=$(PWD) modules_install

clean:

rm -rf *.o *.ko *~ core .depend *.mod.c .*.cmd .tmp_versions .*.o.d

endif

make 即可後產生 .ko .mod.o .mod.c ... etc
