Add static library to podspec

My podspec requires a static library (OpenSSL). For convenience, I’m shipping the library with the pod.

The static library contains:

  • Xcode: Copy Headers: Public vs. Private vs. Project?
  • XCode 4.3: Static Library Generation
  • Use AdobeMobileLibrary (for iOS) with cocoapods?
  • How to build a C library for iOS by Xcode 6?
  • Xcode4 Create Static Library from Existing Project
  • What is the correct process for linking static libraries that have common static libraries?
    • Binaries: MyPod/openssl/bin/libcrypto.a and MyPod/openssl/bin/libsll.a
    • Headers: MyPod/openssl/include/openssl/*.h
    • Its own license (in addition to my project’s license): MyPod/openssl/include/LICENSE

    What is the proper way of expressing this in my podspec? I’ve seen various example that use combinations of the following properties and I’m currently trying different combinations:

    source_files
    public_header_files
    private_header_files
    preserve_paths
    libraries
    xcconfig
    vendored_libraries
    

    Or even better, can I define this static library in a subspec?

    I managed to add the static library as a subspec. I prefer this approach because it uses the build shipped with my pod by default, and also enables users to provide their own build if they so desire.

    As mentioned, the static library is OpenSSL but the following applies to any static library. I’m using the following directory structure:

    libraries/openssl-1.0.1e/include/openssl/*.h
    libraries/openssl-1.0.1e/LICENSE
    libraries/openssl-1.0.1e/lib/*.a
    

    The resulting subspec would be:

    s.subspec 'OpenSSL' do |openssl|
        openssl.preserve_paths = 'libraries/openssl-1.0.1e/include/openssl/*.h', 'libraries/openssl-1.0.1e/include/LICENSE'
        openssl.vendored_libraries = 'libraries/openssl-1.0.1e/lib/libcrypto.a', 'libraries/openssl-1.0.1e/lib/libssl.a'
        openssl.libraries = 'ssl', 'crypto'
        openssl.xcconfig = { 'HEADER_SEARCH_PATHS' => "${PODS_ROOT}/#{s.name}/libraries/openssl-1.0.1e/include/**" }
    end
    

    Line by line:

    openssl.preserve_paths = 'libraries/openssl-1.0.1e/include/openssl/*.h', 'libraries/openssl-1.0.1e/include/LICENSE'
    

    Preserve headers and the license file. We will use the headers below.

    openssl.vendored_libraries = 'libraries/openssl-1.0.1e/lib/libcrypto.a', 'libraries/openssl-1.0.1e/lib/libssl.a'
    

    Tell CocoaPods that we are shipping the above static libraries in the pod. This will preserve the files, as well as modifying LIBRARY_SEARCH_PATHS accordingly.

    openssl.libraries = 'ssl', 'crypto'
    

    Includes the libraries in “Other Linker Flags”.

    openssl.xcconfig = { 'HEADER_SEARCH_PATHS' => "${PODS_ROOT}/#{s.name}/libraries/openssl-1.0.1e/include/**" }
    

    Tells the project where to find the headers. We cannot use public_header_files because this is a subspec.

    You can try do it like it’s done here https://github.com/krzak/OpenSSL, or just use this Pod with you project if you find it convienence

    pod 'OpenSSL', :podspec => 'https://raw.github.com/krzak/OpenSSL/master/OpenSSL.podspec'
