Mac shell編譯安裝openssl for Mac and iOS

想做一個ios加密專案，用到openssl，故用指令碼傻瓜式下載、編譯、安裝，shell指令碼改自https://gist.github.com/armadsen/b30f352a8d6f6c87a146，openssl版本為openssl-1.0.2n,可自己修改，在我將此指令碼命名為build-openssl.sh,在安裝目錄下用iterm2輸入./build-openssl.sh，注意指令碼的許可權問題。

貼上shell指令碼

#!/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
