编译字符设备驱动file_operations结构问题? 为什么链接不到usr/src/linux2.4.20/inclu

编译命令:gcc -D_KERNEL_ -DMODULE -DLINUX -I/usr/src/linux-2.4.20-8/include -c -o CharDriver.o CharDriver.c
结果:
CharDriver.c: At top level:
CharDriver.c:17: warning: `struct inode' declared inside parameter list
CharDriver.c:36: warning: `struct file' declared inside parameter list
CharDriver.c:36: warning: `struct inode' declared inside parameter list

CharDriver.c:58: variable `tdd_fops' has initializer but incomplete type

我的linux为Red Hat linux 9，我认为这里出现上述的问题主要是因为链接到了/usr/include/linux/fs.h

单位的机房一直要找个网管软件，我就采纳楼上建议用了美信云网管，配置操作挺简单的，
还是免费的，就是希望监测可以在全面点，就完美了。、
