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.

openssl-build.sh

#!/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

Where is ./Configure supposed to come from?

Thanks!

how to use this script? need openssl source code or just dump from macos lib?

When was the last time was updated or even tested..?

This is the 3rd "github" script I've tried...
None of them have worked...

It's virtually identical to 2 other Github openssl / curl projects.

This one makes it to:

Cleaning up
Using openssl-1.1.0c.tar.gz
Unpacking openssl
Building openssl-1.1.0c for i386
-- abruptly ends ---
$ Oh, back to command prompt...

For anyone interested. You can try this repo https://github.com/sinofool/build-openssl-ios I've had success with this.
