Build OpenSSL for iOS

OpenSSL的版本为1.0.2h

编译脚本如下：

#!/bin/bash# This script builds the iOS and Mac openSSL libraries# Download openssl http://www.openssl.org/source/ and place the tarball next to this script# Credits:# https://github.com/st3fan/ios-openssl# https://github.com/x2on/OpenSSL-for-iPhone/blob/master/build-libssl.shset -eusage (){echo "usage: $0 [minimum iOS SDK version (default 7.0)]"exit 127}if [ $1 -e "-h" ]; thenusagefiMIN_SDK_VERSION="7.0"if [ -z $1 ]; thenSDK_VERSION="9.3"elseSDK_VERSION=$1fiOPENSSL_VERSION="openssl-1.0.2h"DEVELOPER=`xcode-select -print-path`buildMac(){ARCH=$1echo "Building ${OPENSSL_VERSION} for ${ARCH}"TARGET="darwin-i386-cc"if [[ $ARCH == "x86_64" ]]; thenTARGET="darwin64-x86_64-cc"fipushd . > /dev/nullcd "${OPENSSL_VERSION}"./Configure ${TARGET} --openssldir="/tmp/${OPENSSL_VERSION}-${ARCH}" &> "/tmp/${OPENSSL_VERSION}-${ARCH}.log"make >> "/tmp/${OPENSSL_VERSION}-${ARCH}.log" 2>&1make install >> "/tmp/${OPENSSL_VERSION}-${ARCH}.log" 2>&1make clean >> "/tmp/${OPENSSL_VERSION}-${ARCH}.log" 2>&1popd > /dev/null}buildIOS(){ARCH=$1pushd . > /dev/nullcd "${OPENSSL_VERSION}"  if [[ "${ARCH}" == "i386" || "${ARCH}" == "x86_64" ]]; thenPLATFORM="iPhoneSimulator"elsePLATFORM="iPhoneOS"sed -ie "s!static volatile sig_atomic_t intr_signal;!static volatile intr_signal;!"
