    <p>I wanted to start using boost:python to embed python in my C++ program, but I am already having problems with this simple code:</p> <pre><code>#include &lt;boost/python.hpp&gt; //boost libraries #include &lt;Python.h&gt; //python libraries using namespace boost::python; int main() { Py_Initialize(); object main_module = import("__main__"); object main_namespace = main_module.attr("__dict__"); return 0; } </code></pre> <p>I'm just starting the interpreter and importing the main module but the compiler already have problems with that:</p> <pre><code>/home/i7941878/Code/pythonTest/main.cpp:-1: error: undefined reference to `boost::python::detail::str_base::str_base(char const*)' /home/i7941878/Code/pythonTest/main.cpp:-1: error: undefined reference to `boost::python::import(boost::python::str)' /home/i7941878/Code/pythonTest/main.cpp:-1: error: undefined reference to `boost::python::api::getattr(boost::python::api::object const&amp;, char const*)' </code></pre> <p>I don't have a clue why I am getting those errors. I am pretty sure boost:python is built correctly.</p> <p>Anyone able to enlight me?</p> <p>I am using QT creator to build and compile. If I compile using G++ with <code>-I/usr/include -I/usr/include/python2.6 main.cpp</code> I get:</p> <pre><code>/tmp/ccI8x97b.o: In function `main': main.cpp:(.text+0xc): undefined reference to `Py_Initialize' main.cpp:(.text+0x30): undefined reference to `boost::python::import(boost::python::str)' /tmp/ccI8x97b.o: In function `boost::python::api::object::object()': main.cpp:(.text._ZN5boost6python3api6objectC2Ev[_ZN5boost6python3api6objectC5Ev]+0xd): undefined reference to `_Py_NoneStruct' /tmp/ccI8x97b.o: In function `boost::python::api::const_attribute_policies::get(boost::python::api::object const&amp;, char const*)': main.cpp:(.text._ZN5boost6python3api24const_attribute_policies3getERKNS1_6objectEPKc[boost::python::api::const_attribute_policies::get(boost::python::api::object const&amp;, char const*)]+0x26): undefined reference to `boost::python::api::getattr(boost::python::api::object const&amp;, char const*)' /tmp/ccI8x97b.o: In function `boost::python::str::str(char const*)': main.cpp:(.text._ZN5boost6python3strC2EPKc[_ZN5boost6python3strC5EPKc]+0x1f): undefined reference to `boost::python::detail::str_base::str_base(char const*)' collect2: ld returned 1 exit status </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
