QTCPServer调用listen()失败打印出地址无效是怎么回事？
if(! server->listen(QHostAddress(ip),port)) {
qDebug()<<server->errorString();
return;
}
打印出来的错误信息是：The address is not available
【不是代码问题，也不是IP地址和端口号的填写问题】。另外一台机子上正常运行，换成win10的机子就不行
Google出来有人遇到相同的问题是这么解决的，是怎么回事：
Problem Solved, there was nothing wrong in the code, it was issues with my WLAN i have manual ip for WLAN, which was not working for my app
, i got mac of device bind with an ip in DHCP, now device get ip from DHCP and every thing is good.
