code：：block中如何能编译有qt库的程序

lyw08china

代码如下
#include <iostream>
#include <cassert>
#include <string>
#include <QFile>
#include <QTextStream>
int main()
{
    string="F:\\qtex\\20131115_1815.txt";
    QFile qfile( QString::Local8Bit( strfile.c_str( ) ) );
    cout << "CEFileUtil::readEFile:" << strfile << endl;
    QTextStream qfs( &qfile );
    while (!qfs.atEnd( ))
    {
        const QString qstrline = qfs.readLine( ).simplified( );
        cout << "readLine:" << qstrline.Local8Bit( ).data( ) << endl;
    }
}
编译结果如下？

这个明显是你的编译路径不对，最基本的gcc命令，你需要在后面加 -I($dir) 指定你的头文件查找位置，-L($dir)指定你的动态库查找位置， 另外对于QT中QObeject类，是需要先用Qt自带的moc编译器先展开后再编译，具体的资料去搜搜看。初学者不建议用其它编译器编译。

    #include <QtCore\QString>
#include <QtCore\QTextCodec>
#include <QtCore\QFile>
#include <QtCore\QTextStream>
#include <QtCore\QByteArray>
很奇怪，加了QtCore好使了，不管怎么样多谢您回复 2# luciker1988
