怎么ldd3的sculld编译运行有问题

ww2000e

是2.6.10内核树

书上带的例子没动
编译时

1. 
   
2. [root@localhost sculld]# make
   
3. make -C /lib/modules/2.6.10/build M=/root/ldd3/sculld LDDINC=/root/ldd3/sculld modules
   
4. make[1]: Entering directory `/root/linux-2.6.10'
   
5.   Building modules, stage 2.
   
6.   MODPOST
   
7. *** Warning: "register_ldd_driver" [/root/ldd3/sculld/sculld.ko] undefined!

找到那几个undefined函数后,编译不报warning了,但是插入又报

insmod报这个错

sculld应该怎么运行?
