<p>Hello! I have been developing a framwork on ocaml for mobile platforms. The main idea is to create a universal 2D framework for game development. I started with porting &quot;sparrow&quot; <a href="http://www.sparrow-framework.org/" target="_blank">http://www.sparrow-framework.org</a> framework from objc to ocaml.</p>


<p>Repository <a href="https://github.com/serp256/Lightning" target="_blank">https://github.com/serp256/Lightning</a>. The repository does not include the entire project yet, I will commit the rest as soon as possible. I have successfully launched the project on iOS, and SDL version on macosx and linux.</p>


<p>Now I&#39;m trying to port it on android, and after that there will be an official release of the framework with the first game on it. </p>
<p>However, I encountered an unclear issue.</p>
<p>When I tried to launch it on android, I received an errorr sigsegv which always occurs on ocaml_startup in case objects are used in the code.</p>
<p>To compile ocaml for android I&#39;m using the patch from &quot;<a href="http://www.itpl.co.jp/ocaml-nagoya/index.php?ocaml-android" target="_blank">http://www.itpl.co.jp/ocaml-nagoya/index.php?ocaml-android</a>&quot;. </p>

<p>I don&#39;t know very well arm assembler, but I&#39;m trying to solve this problem. Can someone from the maillist help me</p></div><div><br></div><div><br></div><div>=== test_stub.c ===</div><div><div>#include &lt;jni.h&gt;</div>
