< p > Building the libtorrent python bindings will produce a shared library (DLL)
which is a python module that can be imported in a python program.< / p >
< p > The only supported build system for the bindings are currently boost build. To
set up your build environment, you need to add some settings to your
< tt class = "docutils literal" > < span class = "pre" > $BOOST_BUILD_PATH/user-config.jam< / span > < / tt > .< / p >
< p > Make sure your user config contains the following line:< / p >
< pre class = "literal-block" >
using python : 2.3 ;
< / pre >
< p > Set the version to the version of python you have installed or want to use. If
you've installed python in a non-standard location, you have to add the prefix
path used when you installed python as a second option. Like this:< / p >
< pre class = "literal-block" >
using python : 2.3 : /usr ;
< / pre >
< p > The bindings require < em > at least< / em > python version 2.2.< / p >
< p > For more information on how to install and set up boost-build, see the
< a class = "reference" href = "building.html#step-2-setup-bbv2" > building libtorrent< / a > section.< / p >
< p > Once you have boost-build set up, you cd to the < tt class = "docutils literal" > < span class = "pre" > bindings/python< / span > < / tt >
directory and invoke < tt class = "docutils literal" > < span class = "pre" > bjam< / span > < / tt > with the apropriate settings. For the available
build variants, see < a class = "reference" href = "building.html#step-3-building-libtorrent" > libtorrent build options< / a > .< / p >
< p > For example:< / p >
< pre class = "literal-block" >

< p > On Mac OS X, this will produce the following python module:< / p >
< pre class = "literal-block" >
bin/darwin-4.0/release/dht-support-on/link-static/logging-none/threading-multi/libtorrent.so

< p > The python interface is nearly identical to the C++ interface. Please refer to
the < a class = "reference" href = "manual.html" > main library reference< / a > .< / p >
< p > For an example python program, see < tt class = "docutils literal" > < span class = "pre" > client.py< / span > < / tt > in the < tt class = "docutils literal" > < span class = "pre" > bindings/python< / span > < / tt >
directory.< / p >
< p > A very simple example usage of the module would be something like this:< / p >
< pre class = "literal-block" >
