**zlib编译详见**  
[https://blog.csdn.net/zhangxuechao\_/article/details/85049711][https_blog.csdn.net_zhangxuechao_article_details_85049711]

**下载quazip**  
[https://github.com/stachenov/quazip][https_github.com_stachenov_quazip]

**也可直接下载我配置好的quazip**  
[https://github.com/zwx230741/quazip.git][https_github.com_zwx230741_quazip.git]

**加入头文件**  
在quazip中创建include文件夹  
![1][]  
将zlib头文件拷贝到include文件夹下  
![2][]  
**加入动态库文件**  
在quazip中创建lib文件夹  
![1][1 1]  
将zlib编译好的动态库拷贝到lib文件夹下  
![2][2 1]  
**quazip工程配置**  
修改quazip.pro工程文件。添加头文件路径和动态库路径

INCLUDEPATH += $$PWD/include
    LIBS += -L$$PWD/lib -lzlib1

![3][]  
**编译动态库**  
![3][3 1]  
**不加入头文件，报以下错误**  
![4][]

--------------------

**创建测试工程quazipTest**  
同理，创建include和lib目录。分别放头文件和动态库文件  
![5][]  
**拷贝头文件**  
从quazip拷贝所有头文件  
![2][2 2]  
**拷贝库文件**  
拷贝刚刚生成的动态库文件。`quazipd.dll`是Debug生成的，`quazipd.dll`是Release生成的，`zlib1.dll`是zlib动态库  
![3][3 2]  
**quazipTest工程配置**  
修改quazipTest.pro工程文件。添加头文件路径和动态库路径

INCLUDEPATH += $$PWD/include
    
    CONFIG(debug, debug|release) {
        LIBS += -L$$PWD/lib -lquazipd
    } else {
        LIBS += -L$$PWD/lib -lquazip
    }

**添加压缩解压代码**

#include "mainwindow.h"
    #include <QApplication>
    #include <JlCompress.h>
    
    int main(int argc, char *argv[])
    {
        QApplication a(argc, argv);
        MainWindow w;
        w.show();
    
        JlCompress::compressDir("D:/testzip/a.zip", "D:/testzipdir1");
        JlCompress::extractDir("D:/testzip/a.zip", "D:/testzipdir2");
        
        return a.exec();
    }
