换了内核，ubuntu也启动了～还是不能make～

lxyscls

由于目标系统是2.6.29.1的，但是ubuntu804是2.6.24的～

原系统下面有/lib/modules/2.6.24-generic/build，该文件实际是/usr/src/linux-headers-2.6.24-16-generic的链接～

但是指定以这个为目标无法build～

万般无奈，只好试着换个内核——2.6.29.1，下载源码，完全没有配置，然后make , make modules, make modules_install, make install, make bzImage都作了，再用initramfs作了个文件系统，OK，以该内核和文件系统启动也没有问题～

还是无法build！！！总是提示nothing to be done for modules——makefile按照置顶帖里面写的，应该没什么问题——
用strace跟了一下，输出如下（省略了一些前面的东西，直接从打开makefile此处开始）

换成debian4.0出现同样的情况！why?why?why?

dreamice

这种内核升级，总是出现一些稀奇古怪的问题，好好分析一下原因

lxyscls

娘亲啊～

我现在下载了ldd3的example包，然后什么都不改——make，还是出错～

我确定ubuntu804下面是存在内核代码树的～为什么～

make.mo是个什么东东啊～

lxyscls

我泪奔～

FC8下面什么都不做——可以make，没有问题～

insmod也没有问题～

lxyscls

我晕~换到自己笔记本上面的fc8又一次悲惨的挂掉了~

同样的makefile,同样的的驱动文件~

这也太尴尬了吧--strace跟下去好像是open必须文件的问题--前面close掉了再去open系统调用就显示error了~

想起上个星期一个设置网页的项目--同样的系统一个u盘上面不行,但是换到一个新的u盘上面就一切ok了~

这个也太诡异了吧~
