title: how to build openssl on android
body: <p>I am trying to build openssl on android (got from <a href="https://github.com/guardianproject/openssl-android" rel="noreferrer">https://github.com/guardianproject/openssl-android</a>). need to make <strong><code>.so</code></strong> file of this and use in another android project actually. When I try to add all folders of downloaded openssl and build in prompt through ndk-build command, I get an error like this:</p>
  
  <pre><code>Android NDK: Trying to define local module 'openssl' in workspace/project/apps/Android.mk.
  
  Android NDK: But this module is was already defined by workspace/project/apps/Android.mk.
  
  android-ndk-r8b/build/core/build-module.mk:34:
  *** Android NDK: Aborting.. Stop.
  </code></pre>
  
  <p>Please let me know how to build .so file!!</p>
