    <p>I've installed boost python from ubuntu 9.04 repositories. I've successfully run <a href="http://www.boost.org/doc/libs/1_41_0/more/getting_started/unix-variants.html#build-a-simple-program-using-boost" rel="noreferrer">Build a Simple Program Using Boost</a> from the tutorial, so I know that boost python is installed on my system.</p> <p>However, the program below returns an error:</p> <pre><code>#include &lt;string&gt; namespace { // Avoid cluttering the global namespace. // A couple of simple C++ functions that we want to expose to Python. std::string greet() { return "hello, world"; } int square(int number) { return number * number; } } #include &lt;boost/python.hpp&gt; using namespace boost::python; BOOST_PYTHON_MODULE(getting_started1) { // Add regular functions to the module. def("greet", greet); def("square", square); } </code></pre> <p>I tried to execute the first step from the below two steps to create a shared library:</p> <pre><code>g++ -c -fPIC hello.cpp -o hello.o g++ -shared -Wl,-soname,libhello.so -o libhello.so hello.o </code></pre> <p>(Are these the right commands?)</p> <p>The following is the complete error output:</p> <pre><code>In file included from /usr/include/boost/python/detail/prefix.hpp:13, from
