编译一个qt调用Mplayer的程序，make的时候，总是显示widget没有名为ui的字段
widget.cpp代码如下：
#include "widget.h"
#include "ui_widget.h"

Widget::Widget(QWidget *parent)
    : QWidget(parent), ui(new Ui::Widget)
{
    ui->setupUi(this);
    widget_mplyaer = new QWidget(this);

    startButton= new QPushButton("play");
    connect(startButton,SIGNAL(clicked()),this,SLOT(doMplayer()));

    process = new QProcess(this);
    connect(process, SIGNAL(finished(int, QProcess::ExitStatus)),this, SLOT(mplayerEnded(int, QProcess::ExitStatus))); //mplayerEnded在后面

    widget_mplyaer->setSizePolicy(QSizePolicy(QSizePolicy::Preferred, QSizePolicy::Preferred));
    widget_mplyaer->setAttribute(Qt::WA_OpaquePaintEvent );
    widget_mplyaer->setMinimumSize(500, 500);

    QVBoxLayout *layout = new QVBoxLayout;
    layout->addWidget(widget_mplyaer);
    layout->addWidget(startButton);
    setLayout(layout);

    initValue();
}

void Widget::mplayerEnded(int,QProcess::ExitStatus)
{
    process->write("quit");
    if(!process->waitForFinished(100))
    return;
    startButton->setText("play");
    isPlaying = false;
}

void Widget::doMplayer()
{
    if(startButton->text() == "play")
    {
        qDebug()<<"play ";
        QString pro = "./mplayer";
        QStringList slist;
        slist << "-slave";
        slist << "-quiet";
        slist << "-wid" << QString::number(widget_mplyaer->winId());
        slist << "2.rm";
        process->start(pro,slist);

        if(!process->waitForStarted(100))
            return;
        startButton->setText("stop");
        isPlaying = true;
    }else
    {
        if(!isPlaying)
            return;
        qDebug()<<"stop ";
        process->write("q");
        process->kill();
        widget_mplyaer->repaint();

        if(!process->waitForFinished(100))
            return;
        startButton->setText("play");
        isPlaying = false;
    }

}

void Widget::initValue()
{
    isPlaying = false;
}

Widget::~Widget()
{
    delete ui;
}

void Widget::closeEvent(QCloseEvent *event)
{
    process->write("quit");
    process->kill();
    if(!process->waitForFinished(100))
        return;
    event->accept();
}

头文件呢？
方便打包工程上来让大家编译看看么

恩……好的，这个是头文件代码：
#ifndef WIDGET_H
#define WIDGET_H

#include <QtGui/QWidget>
#include <QVBoxLayout>
#include <QProcess>
#include <QPushButton>
#include <QDebug>
#include <QCloseEvent>

class Widget : public QWidget
{
    Q_OBJECT

public:
    Widget(QWidget *parent = 0);
    ~Widget();
private slots:
    void doMplayer();
    void mplayerEnded(int, enum QProcess::ExitStatus);
protected:
    void closeEvent(QCloseEvent *);
private:
    QPushButton *startButton;
    void initValue();
    bool isPlaying;
    QWidget *widget_mplyaer;
    QProcess *process;
};

#endif // WIDGET_H
