我电脑上的虚拟机用的是ubutu内核是2.6.35，我买了Tiny6410的开发板，内核是2.6.38，我本来想写一个hello world的驱动程序，Makefile编译后，下到开发板上运行的。可是编译总是出错。请大家帮我看看是怎么回事？错误显示如下：
linux@ubuntu:~/friendly-arm/hello-drv$ make
make -C /home/linux/friendly-arm/linux-kernel/linux-2.6.38/ M=`pwd` modules
make[1]: Entering directory `/home/linux/friendly-arm/linux-kernel/linux-2.6.38'
ERROR: Kernel configuration is invalid.

Run 'make oldconfig && make prepare' on kernel src to fix it.

我的Makefile如下：
obj-m := hello.o
PWD := 'pwd'
KDIR := /home/linux/friendly-arm/linux-kernel/linux-2.6.38/
default:
make -C $(KDIR) M=$(PWD) modules
clean:
make -C $(KDIR) M=$(PWD) clean
麻烦好心人帮我看看，万分感谢。
