Installing Py4s

1. Install RDFlib either the release or SVN version will do
2. Install Cython version 0.12 – beware that the debian/ubuntu packaged version is too old

   easy_install cython

   or

   pip install cython

   —
3. Install the latest version of Raptor and Rasqal from Redland – with the usual method of installing source packages if your operating system does not include recent enough versions

   ./configure && make && make install

4. Make sure when installing Rasqal to configure using ‘—enable-query-languages=sparql rdql laqrs’
5. Get the latest 4store from https://github.com/garlik/4store or from https://github.com/wwaites/4store — the latter supports multiple simultaneous clients, but is very new
6. Configure and build as normal:

   ~/src/4store$ ./configure && make && make test

7. Install and optionally create a test triplestore:

   ~/src/4store$ 4s-backend-setup py4s_test ; 4s-backend py4s_test

8. Build the Py4s bindings:

   ~/src/py4s$ python setup.py build

9. Install in the normal way:

   ~/src/py4s$ python setup.py install

10. Run the tests:

    ~/src/py4s$ nosetests -v -s

Note that though Py4s is distributed on the cheeseshop, easy_install cannot be used because it
requires the presence of the 4store sources in order to build.
