设备驱动程序开发的编译问题

zoe_cs

先谢谢大家的帮忙了啊

/*
*        Hello world module.
*/
//#include <linux/init.h>

#include <linux/module.h>

#if defined(CONFIG_SMP)
#define __SMP__
#endif

#if defined(CONFIG_MODVERSIONS)
#define MODVERSIONS
#include <linux/modversions.h>
#endif

#include <linux/kernel.h>

static __init int init_module(void)
{
        printk(KERN_DEBUG "Hello, kernel!\n");
        return 0;
}

static __exit void cleanup_module(void)
{
        printk(KERN_DEBUG "Good-bye, kernel!\n");
}

这个是Linux程序设计上设备驱动程序开发的代码
我是在虚拟机上安装的CentOS-4.6

我按照书上的编译命令
gcc -D__KERNEL__-DMODULE -DMODVERSIONS -I /user/src/kernels/2.6.9-67.EL-smp-i686/include -Wall -O2  -o hello -c hello.c
但是出现了 <command line>:1:11: warning: ISO C requires whitespace after the macro name
In file included from /usr/include/linux/module.h:10,
                 from hello.c:6:

把相关头文件include进来吧，为了省麻烦，我一般

1. #include <linux/module.h>
   
2. #include <linux/types.h>
   
3. #include <linux/fs.h>
   
4. #include <linux/errno.h>
   
5. #include <linux/mm.h>
   
6. #include <linux/sched.h>
   
7. #include <linux/init.h>
   
8. #include <linux/cdev.h>
   
9. #include <linux/poll.h>
   
10. #include <asm/io.h>
    
11. #include <asm/system.h>
    
12. #include <asm/uaccess.h>

而且这个不是2.6内核的写法？我记得是

1. int drv_init()
   
2. {
   
3. 
   
4. }
   
5. 
   
6. void drv_exit()
   
7. {
   
8.    
   
9. }
   
10. 
    
11. module_init(drv_init);
    
12. module_exit(drv_exit);
