qt创建SOCKET编译报错 ?报错

QStringhostip="192.168.168.113";
qint16port=8000;
psocket=newQTcpSocket;
psocket->connectToHost(QHostAddress(hostip),port);

将变量的申明放在一个函数块的头部，好像改成这样就好了

intsock_send(){WSADATAWSAdata;WORDver;SOCKETst;structsockaddr_inaddr;WSAStartup(ver,&WSAdata);st=socket(AF_INET,SOCK_DGRAM,0);memset(&addr,0,sizeof(addr));addr.sin_addr.S_un.S_addr=inet_addr("127.0.0.1");addr.sin_family=AF_INET;addr.sin_port=htons(8080);return0;}

试了下楼主的代码，在我的电脑上是能跑的，楼主要不删了build-XXXX-XX-XX文件夹，重新生成一下试试

#include<WinSock2.h>intsock_send(){WSADATAWSAdata;WORDver;WSAStartup(ver,&WSAdata);SOCKETst=socket(AF_INET,SOCK_DGRAM,0);structsockaddr_inaddr;memset(&addr,0,sizeof(addr));addr.sin_addr.S_un.S_addr=inet_addr("127.0.0.1");addr.sin_family=AF_INET;addr.sin_port=htons(8080);return0;}
