在GPIO内核驱动中有个驱动链接库的问题想和大家讨论一下

qiangtoucao121

我现在想直接编译Linux内核中的在drvier/gpio/下的gpio单独的驱动程序，当我编译时，显示缺少gpiolib的库，请问我该如何写自己的Makefile才能让编译成功，谢谢！
我的Makefile如下：
  1 ifneq ($(KERNELRELEASE),)
  2 #       support-y := ./gpiolib.o
  3         obj-m := gpio-sch.o
  4         support-y := gpiolib.o
  5 else
  6         KERNELDIR ?= /lib/modules/$(shell uname -r)/build
  7         PWD := $(shell pwd)
  8 default:
  9          $(MAKE) -C $(KERNELDIR) M=$(PWD) modules -I/home/fxg/linux-2.6.32/include
10 endif

make后报错如下：
make -C /lib/modules/2.6.32-71.el6.x86_64/build M=/home/fxg/test/drivers/gpio modules -I/home/fxg/linux-2.6.32/include
