Build
-----

Execute the following commands to build NLSR:

.. code-block:: sh

    ./waf configure
    ./waf
    sudo ./waf install

Refer to ``./waf --help`` for more options that can be used during the configure stage and
how to properly configure NLSR.

If your pkgconfig path is not set properly, you can do the following before running ``./waf
configure``:

.. code-block:: sh

    export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
    # or
    export PKG_CONFIG_PATH=/path/to/pkgconfig/on/your/machine

If ChronoSync support is desired, NLSR needs to be configured with the following option:

.. code-block:: sh

    ./waf configure --with-chronosync
