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,
  from hello.c:1:

我是新手，请高人指点啊，


------解决方案--------------------
找LDD3上的makefile试试
------解决方案--------------------
_D__KERNEL__ ==> -D__KERNEL__
