西理工的网通让我头痛

[run612]

我是学飞菜鸟，前天刚入手。装系统用wubi，很好用，不到20分钟就装好了，一点问题也没有。
但是当我想在ubuntu 上网的时候问题就出现了，先是连不上网，照前面高手说的，建一个dsl，结果能连上了。
可是，我用了两个上午装wincap插件，也就是ishare.exe。请教了学校的高手，用wine装，也装上了，运行时老是说缺少那4个.dll文件，我也cp过去了，在.wine/drive_c/windows/system32/里ls之后也能看到那 4个.dll。但当我在.wine/dirve_c/Program\ Files/PPOE/里运行wine ishare_user.exe时还是说缺少那几个.dll。
请高手们指教一下！！posting.php?mode=post&f=134#

将下面的源码用GCC编译，在pppoe拨号之后运行程序（pppoe需要设定DNS服务器，在xp里面控制台-ipconfig /all，得到的两个地址都写上）
