libzip開發筆記（一）：libzip庫介紹、編譯和工程模板

 

前言

  Qt使用一些壓縮解壓功能，選擇libzip庫，libzip庫比較原始，也是很多其他庫的基礎支撐庫。

 

libzip

  libzip是一個C庫，用於讀取，建立和修改zip檔案。可以從資料緩衝區，檔案或直接從其他zip歸檔檔案直接複製的壓縮資料中新增檔案。在不關閉存檔的情況下所做的更改可以還原。
  當前版本是1.7.3，於2020年7月15日釋出。

libzip編譯

步驟一：解壓

步驟二：Cmake配置（vs2017 x64版本）

  需要zlib，之前已經編譯過vs2017 x64版本的zlib了，匯入再配置

步驟三：生成工程

步驟四：開啟VS2017編譯

步驟五：安裝install

 

模組化

 

補充：檢視命令列工具幫助和原始碼輔助開發

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)
