本文导语: 请大家帮忙： #include 只要包含这个头就出现错误： [root@localhost test_module]# make gcc -Wall -DMODULE -D__KERNEL__ -DLINUX -I/usr/include/ -c hello.c In file included from /usr/include/linux/fs.h:23, from /usr/incl...

请大家帮忙：
#include
只要包含这个头就出现错误：

怎么回事，谢谢！

加入kernel的include路径，-I/usr/src/linux-2.4/include
另外就是系统自带的kernel source最好配置好后make dep
