驱动编译遇挫,求大虾帮忙
飞凌Linux3.0.1里的drivers里找出来的led驱动,驱动没问题,仅作参考,主要是把C文件拿到内核外用我的Makefile编译,会出错,求解决

附我的Makefile文件:
obj-m := ./ok6410_leds.o
PWD := $(shell pwd)
KERNEL_LOCATION = /system/linux-3.0.1
#KERNEL_LOCATION ?= /lib/modules/$(shell uname -r)/build
all:
make -C $(KERNEL_LOCATION) M=$(PWD) modules
clean:
rm -rf *.o *~ core .depend .*.cmd *.ko *.mod.c .tmp_versions
编译时候遇到的错误如下:
[root@zhangwei zw_test]# make
make -C /system/linux-3.0.1 M=/nfs/zw_test modules
make[1]: Entering directory `/system/[color=#FF0000]linux-3.0.1' CC [M] /nfs/zw_test/./ok6410_leds.o

希望谁能帮我解决一下,我自己编写的驱动编译会这样报错,所以找了官方的驱动,确认代码没问题(能够编译正确,正常制作系统镜像),希望哪位大虾帮解决啊
我的arm-linux-gcc版本是4.3.2,原来装过一个低版本的3.4.1,后来我直接把arm那个文件夹删了,重新解压了官方的arm-linux-gcc4.3.2,更改了环境变量PATH,现在能够编译在OK6410板子上执行的程序,我的编译环境应该没什么问题吧
我的情况说清楚了,希望哪位大虾出点主意
[解决办法]
首先,保证你的/system/linux-3.0.1 是已经执行过make的
其次验证工具链配对,执行个arm-xxx-gcc -v
Makefile需要定义ARCH 和工具链前缀,沾一个我正在用的,其实也没啥大区别
ARCH = mipsCC = mips64el-linux-gccDEBFLAGS=-O2obj-m += xio2221-eeprom.oKERNELDIR ?= /home/xy/3a/linux-loongson3a-2.6.36-bncPWD :=$(shell pwd)all: make -C $(KERNELDIR) M=$(PWD) modulesclean: make -C $(KERNELDIR) M=$(PWD) clean
