我有一个项目要解压缩文件。我发现 Quazip 接近我想要的实现(检查),但是....

编译器在构建项目时说

Makefile.Release:241:警告:覆盖目标版本的命令/moc_quazipfile.o' release\moc_quazipfile.cpp:40:警告:'static void QuaZipFile::qt_static_metacall(QObject*, QMetaObject::Call, int, void**) '在没有 dllimport 属性的情况下重新声明:以前的 dllimport 忽略了 release\moc_quazipfile.cpp:48:警告:在被 dll 链接 release\moc_quazipfile.cpp:52 引用后,警告:'QuaZipFile::staticMetaObjectExtraData'在没有 dllimport 属性的情况下重新声明:52:警告: 'QuaZipFile::staticMetaObject ' 在被 dll 链接 release\moc_quazipfile.cpp:61引用后重新声明,没有 dllimport 属性:警告:'virtual const QMetaObject* QuaZipFile::metaObject() const'在没有 dllimport 的情况下重新声明

步骤“Make”时

主窗口.h:

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include "quazip/quazip.h"
#include "quazip/quazipfile.h"


namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();

private:
    Ui::MainWindow *ui;
};

#endif // MAINWINDOW_H

主窗口.cpp:

#include "mainwindow.h"
#include "ui_mainwindow.h"


MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    QuaZip *temp = new QuaZip();
}

MainWindow::~MainWindow()
{

    delete ui;
}

我究竟做错了什么??
