QTcpServer中的incomingConnection函数不执行

之前一个QT socket程序在升级系统后，突然没办法正常工作了。用socket client测试程序，能够连接上tcp server。但是QTcpServer中的incomingConnection函数没有被触发执行。同样的代码在debian7上和windows上都可以执行，但是在debain8就不能正常工作。后来发现，虚函数的incomingConnection的函数参数改变了，有void TripServer::incomingConnection(int socketId) 变成了void TripServer::incomingConnection(qintptr socketId)。参数类型不同，所以函数定义也就不同了。将参数类型有int改成qaintptr就好了。好贱的问题呀。附上server代码

#include "chat_server.h"#include "my_socket.h"#include <QHostAddress>ChatServer::ChatServer( QObject *parent /* = NULL */ )    : QTcpServer( parent ){    _mysockets.empty();}ChatServer::~ChatServer(){    qDeleteAll( _mysockets );    _mysockets.clear();}void ChatServer::Run( quint16 port ){    if( !this->listen(QHostAddress::Any, port) )        printf( "ChatServer listen failed !" );}void ChatServer::sendData(QString string){    printf( "client data to all client!\n" );    QList<MySocket*>::iterator iter;    for( iter = _mysockets.begin(); iter != _mysockets.end(); iter++ ) {        if((*iter)->isOpen())        {            (*iter)->write(qPrintable(string),string.length());        }    }}void ChatServer::sendData(QByteArray string){    printf( "client data to all client!\n" );    QList<MySocket*>::iterator iter;    for( iter = _mysockets.begin(); iter != _mysockets.end(); iter++ ) {        if((*iter)->isOpen())        {            (*iter)->write(string,string.length());        }    }}/*void ChatServer::incomingConnection( int handle )*///修改之前void ChatServer::incomingConnection( qintptr handle )//修改之后{    printf( "incomingConnection(): %d !\n", handle );    MySocket *mysocket = new MySocket( this );    mysocket->setServer(this);    mysocket->setSocketDescriptor( handle );    connect( mysocket, SIGNAL(disconnected()), this, SLOT(clientDisconnected()) );    _mysockets.append( mysocket );}void ChatServer::clientDisconnected(){    printf( "client disconnected !\n" );    QList<MySocket*>::iterator iter;    for( iter = _mysockets.begin(); iter != _mysockets.end(); iter++ ) {        if( -1 == (*iter)->socketDescriptor() ) {            _mysockets.erase( iter );            return;        }    }}
