我在qt 4.4下面作了个小程序，具体是在一个窗口中弹出另一个窗口。。
我写了两个类，一个是directoryviewer，一个是newWindow..然后在directoryviewer中
用newWindow newWindow(text);text是需要传入的文本参数。。
然后显示窗口newWindow..show();
可是make的时候提示undefined reference to 'newWindow:newWindow[in-charge](QString, QWidget*,char const *)'
collect2:ld returned 1 exit status..
我就是用newWindow newWindow(text)调用构造函数。。。可是怎么会在make的最后提示出错呢。。。
下面是我的makefile。。。
