谁能帮我编译通过2行代码<linux/module.h>,我给100分
一个简单的代码:
//hello.c
#include   <linux/kernel.h>
#include   <linux/module.h>

#ifdef   MODEVERSIONS
#include   <linux/modeversions.h>
#endif

int   init_module()
{
printk( "new   module   init... ");
return   1;
}

int   cleanup_module()
{
printk( "module   is   removed ");
return   0;
}


[root@linux   usr]#   gcc   -o   test_app   hello.c  
hello.c:2:26:   错误:linux/module.h:没有那个文件或目录

------解决方案--------------------
不是用gcc直接编译,需要写在Makefile内然后编译。
#Makefile
obj-m += helloworld.o

#make -C /usr/src/kernel/`uname -r`-i686 SUBDIRS=$PWD modules

------解决方案--------------------
hello.c代码
