已经修改了qconfig-qpe.h文件了，并重新configure和make,操作如下：
#//define QT_NO_NETWORKPROTOCOL
可是编译程序还是出现如下问题：
ftpclient.cpp: In member function ‘void FtpClient::slotLogin()’:
ftpclient.cpp:80: 错误：‘class QFtp’没有名为‘connectToHost’的成员
ftpclient.cpp:85: 错误：‘class QFtp’没有名为‘login’的成员
ftpclient.cpp: In member function ‘void FtpClient::slotPut()’:
ftpclient.cpp:97: 错误：‘class QFtp’没有名为‘put’的成员
ftpclient.cpp: In member function ‘void FtpClient::slotGet()’:
