说明

基于libarchive.a + podspec

编译.a静态文件

1. 下载代码 https://github.com/libarchive/libarchive/releases (opens new window)
2. 修改cat/CMakeLists.txt,tar/CMakeLists.txt,cpio/CMakeLists.txt,unzip/CMakeLists.txt,注释掉以下内容

# INSTALL(TARGETS bsdtar RUNTIME DESTINATION bin)
# INSTALL_MAN(${bsdtar_MANS})

3. 生成Xcode代码项目文件

# 进入项目文件夹
# 结果输出到_builds文件夹
cmake -S. -B_builds -GXcode -DCMAKE_SYSTEM_NAME=iOS 

4. 打开_builds文件下的libarchive.xcodeproj项目
5. target选择archive_static,并修改为release模式
6. 开始编译，在Products文件夹获取libarchive.a文件
7. 从libarchive文件夹获取两个头文件archive.h和archive_entry.h

创建podspec

1. 创建pod lib create libarchive，输出如下

What platform do you want to use?? [ iOS / macOS ]
 >  iOS

What language do you want to use?? [ Swift / ObjC ]
 > Swift

Would you like to include a demo application with your library? [ Yes / No ]
 > Yes

Which testing frameworks will you use? [ Quick / None ]
 > None

Would you like to do view based testing? [ Yes / No ]
 > No

2. 复制文件到libarchive/Classes文件夹

# tree libarchive
libarchive
├── Assets
└── Classes
    ├── include
    │   ├── archive.h
    │   └── archive_entry.h
    └── lib
        └── libarchive.a

3. 修改libarchive.podspec文件

添加以下内容

s.static_framework = true
s.vendored_libraries = 'libarchive/Classes/lib/*a'
s.libraries = 'bz2','iconv','z'

修改后内容如下

Pod::Spec.new do |s|
  s.name             = 'libarchive'
  s.version          = '3.7.7'
  s.summary          = 'A short description of libarchive.'
  s.description      = <<-DESC
TODO: Add long description of the pod here.
                       DESC

  s.homepage         = 'https://github.com/Maktub/libarchive'ß
  s.license          = { :type => 'MIT', :file => 'LICENSE' }
  s.author           = { 'Maktub' => '[email protected]' }
  s.source           = { :git => 'https://github.com/xxxxx/libarchive.git', :tag => s.version.to_s }
  # s.social_media_url = 'https://twitter.com/<TWITTER_USERNAME>'

  s.ios.deployment_target = '15.0'

  s.source_files = 'libarchive/Classes/**/*'

  s.static_framework = true
  s.vendored_libraries = 'libarchive/Classes/lib/*a'
  s.libraries = 'bz2','iconv','z'
end

编译后libarchive.framework，目录如下

libarchive.framework
├── Headers
│   ├── archive.h
│   ├── archive_entry.h
│   └── libarchive-umbrella.h
├── Info.plist
├── Modules
│   └── module.modulemap # swift项目使用的关键文件
└── libarchive
