    copied! <p>Can't comment @jkp but his hint did the trick for me. My minimalistic case:</p> <p><em>RenderWorld.h</em></p> <pre class="lang-cpp prettyprint-override"><code>class RenderWorld { public: ... void addEntity(RenderEntity* entity) {entities.push_back(entity);}; std::vector&lt;RenderEntity*&gt; getEntities(void) {return entities;}; private: std::vector&lt;RenderEntity*&gt; entities; }; </code></pre> <p><em>RenderEntity.h</em></p> <pre class="lang-cpp prettyprint-override"><code> class RenderEntity { public: int getID(void) {return 42;}; }; </code></pre> <p><em>python-exportage.py.h</em> (compiles to exported.pyd)</p> <pre class="lang-cpp prettyprint-override"><code>BOOST_PYTHON_MODULE(exported) { class_&lt;RenderWorld&gt;("RenderWorld") .def("addEntity", &amp;RenderWorld::addEntity) .def("getEntities", &amp;RenderWorld::getEntities) ; class_&lt;RenderEntity, RenderEntity*&gt;("RenderEntity") .def("getID", &amp;RenderEntity::getID) ; class_&lt;std::vector&lt;RenderEntity*&gt; &gt;("PyVec") .def(boost::python::vector_indexing_suite&lt;std::vector&lt;RenderEntity*&gt; &gt;()) ; } </code></pre> <p>my python session:</p> <pre class="lang-py prettyprint-override"><code>&gt;&gt;&gt; import exported &gt;&gt;&gt; world = exported.RenderWorld() &gt;&gt;&gt; world &lt;exported.RenderWorld object at 0x00000000024A0E58&gt; &gt;&gt;&gt; e1 = exported.RenderEntity() &gt;&gt;&gt; e1 &lt;exported.RenderEntity object at 0x000000000284DF48&gt; &gt;&gt;&gt; e1.getID() 42 &gt;&gt;&gt; world.addEntity(e1) &gt;&gt;&gt; world.getEntities() &lt;exported.PyVec object at 0x000000000234B1B0&gt; &gt;&gt;&gt; world.getEntities()[0] &lt;exported.RenderEntity object at 0x0000000002441F50&gt; &gt;&gt;&gt; world.getEntities()[0].getID() 42 &gt;&gt;&gt; e1 == world.getEntities()[0] False </code></pre> <p>Notable: The <code>RenderEntity*</code> will be wrapped in an other object. Look at these addresses and the last check. It's logical in a c++ perspective, but not in the python domain.</p> <p><a href="/questions/tagged/c%2b%2b" class="post-tag" title="show questions tagged 'c++'" rel="tag">c++</a></p>
