<p>fastText builds on modern Mac OS and Linux distributions.
Since it uses C++11 features, it requires a compiler with good C++11 support.
These include :</p>
<ul>
<li>(gcc-4.6.3 or newer) or (clang-3.3 or newer)</li>
</ul>
<p>Compilation is carried out using a Makefile, so you will need to have a working <strong>make</strong>.
For the word-similarity evaluation script you will need:</p>
<ul>
<li>python 2.6 or newer</li>
<li>numpy &amp; scipy</li>
</ul>

<p>In order to build <code>fastText</code>, use the following:</p>
<pre><code class="hljs css language-bash">$ git <span class="hljs-built_in">clone</span> https://github.com/facebookresearch/fastText.git
$ <span class="hljs-built_in">cd</span> fastText
$ make
</code></pre>
<p>This will produce object files for all the classes as well as the main binary <code>fasttext</code>.
If you do not plan on using the default system-wide compiler, update the two macros defined at the beginning of the Makefile (CC and INCLUDES).</p>
