Build OpenSSL and libcurl for OS X, iOS and tvOS with Bitcode enabled for iOS, tvOS. Includes patching for tvOS to not use fork().

The build.sh script calls two build scripts:

The openssl-build.sh script creates separate bitcode enabled target libraries for:

• Mac - x86-64
• iOS - iPhone (armv7, armv7s, arm64) and iPhoneSimulator (i386, x86-64)
• tvOS - AppleTVOS (arm64) and AppleTVSimulator (x86-64)

The tvOS build has fork() disable as the AppleTV tvOS does not support fork(). Edit openssl-build.sh to change the version of OpenSSL that will be downloaded and built.

|____lib
   |____libcrypto.a
   |____libssl.a

The libcurl-build.sh script create separate bitcode enabled targets libraries for:

• Mac - x86-64
• iOS - armv7, armv7s, arm64 and iPhoneSimulator (i386, x86-64)
• tvOS - arm64 and AppleTVSimulator (x86-64)

The curl build uses --with-ssl pointing to the above OpenSSL builds. Edit libcurl-build.sh to change the verion of cURL that will be downloaded and built.

|____lib
   |____libcurl_iOS.a
   |____libcurl_Mac.a
   |____libcurl_tvOS.a

Xcode7.1b or later is required for the tvOS SDK.

To include the OpenSSL and libcurl libraries in your Xcode projects, import the following appropriate libraries for your project:

• Curl - curl/lib
• OpenSSL - openssl/Mac/lib, openssl/iOS/lib, openssl/tvOS/lib

1. Do "sh build.sh"

2. Libraries are created in curl/lib, openssl/*/lib

3. Copy libs and headers to your project.

4. Import appropriate "libssl.a", "libcrypto.a", "libcurl.a".

5. Reference Headers, "Headers/openssl", "Headers/curl".

6. Specifying the flag "-lz" in "Other Linker Flags" (OTHER_LDFLAGS) setting in the "Linking" section in the Build settings of the target.

7. To use cURL, see below:

   #include <curl/curl.h>
   
   - (void)foo {    
       CURL* cURL = curl_easy_init();  
       ...  
   }

The AppleTVOS curl build may fail due to a macports "ar" program being picked up (it was in the path - You will see a log message about /opt/local/bin/ar failing in the curl log). A quick cleanup of the path (so that the build uses /usr/bin/ar) fixed the problem. - Thanks to Preston Jennings (prestonj) for this tip.
