    copied!<p>This is more of an answer than a question, because I've figured it out, at least as far as cleanly compiling the library. The main issue for me was to get shared_ptr working.</p> <p><strong>Ingredients:</strong></p> <p>Boost v. 1.45.0</p> <p>The version of STLport at <a href="http://www.anddev.org/viewtopic.php?p=29939">http://www.anddev.org/viewtopic.php?p=29939</a>.</p> <p>Version r4b of the NDK.</p> <p><strong>Directions:</strong></p> <p>In your Android.mk file add:</p> <pre><code>LOCAL_CFLAGS += -DBOOST_EXCEPTION_DISABLE -D_STLP_NO_EXCEPTIONS -DOS_ANDROID -D_STLP_USE_SIMPLE_NODE_ALLOC </code></pre> <p>Remove the call to __stl_throw_length_error at line 613 of stlport/stl/_string.h. You can use _STLP_NO_EXCEPTIONS if you like.</p> <p>Edit boost/boost/smart_ptr/shared_ptr.hpp after line 261 to get rid of the call to boost::throw_exception in the shared_ptr constructor. I used #ifndef BOOST_EXCEPTION_DISABLE around the entire body of the method. (But see the answer below.)</p> <p>Next you need to supply some missing pieces. Create a header file with the following:</p> <pre><code>#ifdef OS_ANDROID #include &lt;exception&gt; namespace std { struct bad_alloc : public exception { bad_alloc operator()(){}}; } #endif </code></pre> <p>and a source file with a stripped-down exception class to support bad_alloc:</p> <pre><code>#ifdef OS_ANDROID #include &lt;exception&gt; namespace std { exception::exception() {} exception::~exception() {} const char* exception::what() const {} } #endif </code></pre> <p>Include the header wherever you're including boost/shared_ptr.hpp. Compile the source and add it to your library.</p>
