Qt开发专栏：三方库开发技术

前言

  Qt使用一些压缩解压功能，选择libzip库，libzip库比较原始，也是很多其他库的基础支撑库。

libzip

  libzip是一个C库，用于读取，创建和修改zip档案。可以从数据缓冲区，文件或直接从其他zip归档文件直接复制的压缩数据中添加文件。在不关闭存档的情况下所做的更改可以还原。   当前版本是1.7.3，于2020年7月15日发布。   官网：libzip.org/   QQ群：1047134658（点击“文件”搜索“libzip”，群内与博文同步更新）

libzip编译

步骤一：解压

步骤二：Cmake配置（vs2017 x64版本）

  需要zlib，之前已经编译过vs2017 x64版本的zlib了，导入再配置

步骤三：生成工程

步骤四：打开VS2017编译

步骤五：安装install

模块化

补充：查看命令行工具帮助和源码辅助开发

ziptool.exe -h
usage: ziptool.exe [-ceghnrst] [-l len] [-o offset] archive command1 [args] [command2 [args] ...]

Supported options are:
        -c              check consistency
        -e              error if archive already exists (only useful with -n)
        -g              guess file name encoding (for stat)
        -h              display this usage
        -l len          only use len bytes of file
        -n              create archive if it doesn't exist
        -o offset       start reading file at offset
        -r              print raw file name encoding without translation (for stat)
        -s              follow file name convention strictly (for stat)
