不好意思 新手入门 VS2008和QT4.5编译Hello小程序, Debug可以 Release链接失败 [复制链接]

Debug编译运行都没有问题 ，relase版本编译链接出错

这个简单的类 头文件如下

#ifndef HELLOQTWINDOWS_H
#define HELLOQTWINDOWS_H

#include <QtGui/QMainWindow>
#include "ui_helloqtwindows.h"

class HelloQtWindows : public QMainWindow
{
    Q_OBJECT

public:
    HelloQtWindows(QWidget *parent = 0, Qt::WFlags flags = 0);
    ~HelloQtWindows();

private:
    Ui::HelloQtWindowsClass ui;

private slots:
    void on_checkBox_stateChanged(int);
    void on_listView_clicked(const QModelIndex &);
};

#endif // HELLOQTWINDOWS_H


实现文件

#include <QMessageBox>
#include <QTranslator>

#include "helloqtwindows.h"

HelloQtWindows::HelloQtWindows(QWidget *parent, Qt::WFlags flags)
    : QMainWindow(parent, flags)
{
    ui.setupUi(this);
}

HelloQtWindows::~HelloQtWindows()
{

}


void HelloQtWindows::on_listView_clicked(const QModelIndex &)
{
    
}

void HelloQtWindows::on_checkBox_stateChanged(int state)
{
    if (Qt::Checked == state)
    {
        QMessageBox::information(this, tr("Test Title"), tr("Checked me!"));
        ui.calendarWidget->setEnabled(false);
    }
    else
    {
        QMessageBox::information(this, tr("Test Title"), tr("Unchecked me!"));
        ui.calendarWidget->setEnabled(true);
    }
}


不知道这个链接错误 与环境设定有关系吗？
为什么Debug可以
我已经详细比较了 2个设定 似乎没有什么问题。
另外我的环境编译了其他网上的例子程序 比较复杂的QT图形程序 Debug和Release都是OK的
