［已解决］错误：Qstring: 没有那个文件或目录 [复制链接]

环境：red flag linux 6.0 SP1,QT 4.4.3

源代码 ：#include <Qstring>
#include <qfile.h>
#include <iostream>

using namespace std;

int main(int argc,char *argv[])
{
Qstring str1;
Qstring str2;
cout<<"please input a file pathname:";
cin>>str1;
cout<<"please input a file new pathname:";
cin>>str2;
QFile file;
file.copy(str1,str2);
return 0;
}

运行时报错：

Qstring是QT4下面库呀，怎么会找不到，请问应该怎么样解决！

lz必定用的linux系统

自己找到了答案，应该是#include <qstring>
http://doc.trolltech.com/4.2/qstring.html  QT网站上的那个是错误的。
