makefile

在一个简单的字符设备驱动程序中实现kfifo使用例子

KERNELDIR = /home/tekkaman/working/SBC2440/linux-2.6.22.2
    # The current directory is passed to sub-makes as argument
PWD := $(shell pwd)
INSTALLDIR = /home/tekkaman/working/rootfs/lib/modules

CROSS_COMPILE	=/home/tekkaman/working/crosstool-gcc410-k26222/gcc-4.1.0-glibc-2.3.2/arm-9tdmi-linux-gnu/bin/arm-9tdmi-linux-gnu-
CC	= $(CROSS_COMPILE)gcc

obj-m := scull_kfifo.o 

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

modules_install:
	cp scull_kfifo.ko $(INSTALLDIR)
clean:
	rm -rf *.o *~ core .depend .*.cmd *.ko *.mod.c .tmp_versions

.PHONY: modules modules_install clean
