在redhat带的内核源码下编译出错,试过标准2.4.20的内核源码,编译成功过自己编译了2.4.20新内核 ,重新来过就出错了,看提示好像是说modversions.h的问题
不过这个目录并没有这个文件,查找到另外一个地方的也是空文件,拷贝过来后,编译能通过,不过安装的模块就是提示
/lib/modules/2.4.20fly/v4l2/v4l1-compat.o: unresolved symbol schedule
/lib/modules/2.4.20fly/v4l2/v4l1-compat.o: unresolved symbol kmalloc

对了,内核的补丁我也已经打过了,在2.4.20上编译顺利
谁能帮我看看,谢了

内核源码目录下,make dep后,再编译驱动试试

果然实在这个问题,谢了,ok了,呵呵
都是redhat自带内核兼容不好引出来的问题,现在换了就好了
