A shell script to build openssl for iOS and Mac. >>>>> It currently builds: Mac (i386, x86_64) >>>>> iOS (armv7, arm64) >>>>> iOS Simulator (i386, x86_64) >>>>> Updated to work with Xcode 7 and produce bitcode enabled binaries >>>>> Minimum deployment target can be easily configured
#!/bin/bash
# This script builds the iOS and Mac openSSL libraries with Bitcode enabled
# Download openssl http://www.openssl.org/source/ and place the tarball next to this script

I'd like to be able to make this script build the dylibs for iOS simulator instead of the static libraries. I've attempted to modify the script to use the shared parameter in ./Configure, however that doesn't seemed to have worked, unless the dylibs are put somewhere I can't find :-)

For anyone who is interested, I managed to work it out. The result of my work is here: http://delphi.radsoft.com.au/2016/03/building-openssl-dylibs-for-ios-simulator/
There's a bunch of stuff specific to Delphi, however the script could be used for any language that can use the dylibs.
