ARM内核模块编译
下面是我用的原码！
1 #include <linux/module.h>
2
3 int int_module(void){
4 printk(" <1> hello world!\n");
5 return 0;
6 }
7
8 void cleanup_module(void){
9 printk(" <1> goodbye!\n");
10 }
我用来编译的命令arm-linux-gcc -o hello.o _D__KERNEL__ -DMODULE -I /home/linux-2.6.38/include -c hello.c
错误为
arm-linux-gcc: _D__KERNEL__: No such file or directory
In file included from /home/linux-2.6.38/include/linux/list.h:4:0,
from /home/linux-2.6.38/include/linux/module.h:9,

我是新手，请高人指点啊，
[解决办法]
找LDD3上的makefile试试
[解决办法]
_D__KERNEL__ ==> -D__KERNEL__
