为什么在2.4.10可通过编译,而在2.4.18就不行了？？？

有一个模块，在linux7.2，内核为2.4.10下，可以顺利编译。而在linux8.0，内核为2.4.18下，就不行了而且报下面的错。
求求各位帮帮忙啦~~~~~~~~~~

look  at   your include path
/usr/src/linux-2.4.18-10 should  be changed to    /usr/src/linux-2.4.18-14
bless!

but in my linux, it is linux-2.4.18-14 already....

OK!!
when compiling, i add a include to \"/usr/src/linux-2.4.18-14\",and it is ok now!!


thanks!!!

 呵呵，搞定就给分吧

在哪个地方加？？？多谢
