Ubuntu10.04 campus Netcom plug-in solution (Western Mail)

Install ishare_user.exe with the network plug-in directly installed in wine. Recently, the plug-in suddenly became unavailable. the reinstallation always reports an error when installing winpcap. If there is no way, google has another method. (I don't know how to send attachments, just paste the source code ......) 1. copy the following

2. Go to the drcom. c directory on the terminal and run gcc drcom. c-o drcom. (If gcc is not installed, run sudo apt-get install gcc first)
3. Run drcom.
If it is difficult to run at startup, you can add it to startup:
System-> preference-> Start application-> Add, and then add drcom.
China West mail's Netcom can do this, but not necessarily in other places.
