编译通不过，着急啊 ，谢谢各位大侠asm/uaccess.h

砍鬼子

以下是我编译字符驱动程序时怎么都通不过的，！不知道是什么原因 ，试过好多次了 ，还是没有成功！下面分别是三种编译方式，还是不行 ，哪位大侠有绝招！谢谢了 ！

第一着：
[root@cslab1 root]# gcc -c lfqudong.c
lfqudong.c:10:25: asm/uaccess.h: 没有那个文件或目录
第二着：
[root@cslab1 root]# gcc -I/usr/src/linux-2.4.20-8/include/asm -c lfqudong.c
lfqudong.c:10:25: asm/uaccess.h: 没有那个文件或目录

第三着：

[root@cslab1 root]# gcc -I/usr/src/linux-2.4.20-8/include -c lfqudong.c
