makefile是这样的
CC= /usr/local/arm/3.4.1/bin/arm-linux-gcc



ifneq ($(KERNELRELEASE),)

        obj-m :=led.o

else

        KDIR :=/linux-2.6.18.2

        PWD :=$(shell pwd)



default:

        $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules

endif

你的arm的kernel在哪个目录下？

frayli

arm kernel在 /linux-2.6.18.2下

frayli

arm的内核编译过了，按照它的提示 make oldconfig&make prepare都没有用 后面的错误我知道是没有linux/devfs_fs_kernel.h文件

frayli

添加了linux/devfs_fs_kernel.h文件，再编译就这样了

这样就是编译通过了
