在ubuntu上安装drcom很简单

只要make&&make install就行了

但在gentoo却遇到了很多问题 ，先是不能编译，少了什么变量，security_ops，然后到网上搜，好不容易找到了一个解决方法，（当时我的内核是2.6.22，后来才更新到2.6.24）

在网友zrx550 http://hi.baidu.com/z%5Fr%5Fx那看到这篇文章 －－－－－－－－－－ linux下的drcom是在2.6的内核中开发的，用到了- 中的security_ops。>但是这个 EXPORT_SYMBOL 在2.6.24的内核中被取消了，导致drcom不能被成功的编译。随之 而来的问题就是新内核在需要drcom的网络环境中不能上网了。就这个问题我请教了开源版>本drcom开发者之一的Wheelz。目前最简单的办法只能修改内核，重新编译。针对2.6.24的>内核,具体办法如下： 1) 在内核的security/security.c文件的最后加上EXPORT_SYMBOL(security_ops); 2) 重新编译一下内核。 3) drcom-1.3.7/kmod/proto.c在#include - 后面加上一句： extern struct security_operations *security_ops; 4）编译安装drcom。

但却始终不起作用，编译了好几次内核，始终没用，后来在.config 中加入

先 grep SECURITY .config 然后vim .config

CONFIG_SECURITY=y CONFIG_SECURITY_NETWORK=y

前几次编译都不成功，好像编译时重新配置内核，立马^C,

然后又一次次偿试，终于可以了。

到这里我发现了一个问题，一般情况了我重新编译内核都不会

make clean 而这次编译了7分钟，所以我觉得它应该将内核重新编译了一遍，以前编译时只要很短的时间，特别是改动很少的时候，因为它没有全部重新编译，只是编译了那些配置改变了的部分，而当它们的依赖关系比较严重时，系统就会自动全部重新编译，所以以后当内核改0动比较大时，最好先make clean下

最后终于安装成功了，但确不能登录，试了好几个方法

drcomcd

drcomc login

drcomc logout

都不行，经过好多次试验才可以上网了

后来发现只有以root用户登录后，

1。drcomd

2登录：drcomc login

3.登出:drcomc logout

然后就一切OK了，然后再以普通用户登录就可以了。

我是在用普通用户登录后，然后Ctrl +Alt +F1,进入一个终端用root登录， 再dromd,drcomc login

登录成功后，再返回到图形界面： Ctrl +Alt +F7

下面是我的调试信息，希望你在检索进能够检索到：
