关于cygwin下skyeye的网络模拟问题请教
如果宿主机操作系统是linux需要加载tun.o模块，那么在cygwin上面没有设备，需要安装其它的什么组件么？如果不需要，我使用Skyeye V1.2Rel 编译成功的skyeye.exe运行testsuite2.1下面的at91/uclinux_rtl8019时，启动画面如下：

从启动画面的提示看是没有找到相关的设备吧，请教一下是什么问题？谢谢 It seems netcard simulation is not supported in cygwin environment. 那请教一下在Windows操作系统上面还有什么方法可以让skyeye支持网卡模拟？谢谢 According to koodailar's anwser, he think MingW environment can let skyeye support netcard simulation on windows. But I have not try it. Good luck! 谢谢，我已经成功的尝试了在MinGW下面的网卡模拟尝试，主要是要先安装VPN里面的TAP-WIN32，作为网卡虚拟共享。
不过遗憾的是SkyEyeV1.2Rel还是不能够直接在MinGW下面编译通过，关于这个问题我已经提交bug到sourceforge了 Thanks.I will look into it.
Can you write your experince here about netcard simulator under MinGW to share with us? That will be very kind. 目前 TAP-WIN32 在 SkyEye 下还是不能使用的，
原来 koodailar 写的这个东西好像有点问题。
过段时间我会把 SkyEye 的 MinGW 环境代码彻底清理一下，
到时我会考虑去除 OpenVPN 依赖，转而使用 Win32 DDK 的东西或类似 vnet 等代替。
请期待下一版本... :)
