<section id="c-libraries">
<h3>C libraries<a class="headerlink" href="#c-libraries" title="Link to this heading">#</a></h3>
<p>Matplotlib brings its own copies of the following libraries:</p>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">Agg</span></code>: the Anti-Grain Geometry C++ rendering engine</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">ttconv</span></code>: a TrueType font utility</p></li>
</ul>
<p>Additionally, Matplotlib depends on:</p>
<ul class="simple">
<li><p><a class="reference external" href="https://www.freetype.org/">FreeType</a> (>= 2.3): a font rendering library</p></li>
<li><p><a class="reference external" href="http://www.qhull.org/">QHull</a> (>= 2020.2): a library for computing triangulations</p></li>
</ul>
<p>By default, Matplotlib downloads and builds its own copies of FreeType (this is
necessary to run the test suite, because different versions of FreeType
rasterize characters differently) and of Qhull. As an exception, Matplotlib
defaults to the system version of FreeType on AIX.</p>
<section id="use-system-libraries">
<h4>Use system libraries<a class="headerlink" href="#use-system-libraries" title="Link to this heading">#</a></h4>
<p>To force Matplotlib to use a copy of FreeType or Qhull already installed in
your system, create a <code class="file docutils literal notranslate"><span class="pre">mplsetup.cfg</span></code> file with the following contents:</p>
<div class="highlight-cfg notranslate"><div class="highlight"><pre><span></span><span class="k">[libs]</span>
<span class="na">system_freetype</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="s">true</span>
<span class="na">system_qhull</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="s">true</span>
</pre></div>
</div>
<p>before running</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>python<span class="w"> </span>-m<span class="w"> </span>pip<span class="w"> </span>install<span class="w"> </span>.
</pre></div>
</div>
<p>You can also use the <span class="target" id="index-0"></span><a class="reference internal" href="../users/installing/environment_variables_faq.html#envvar-MPLSETUPCFG"><code class="xref std std-envvar docutils literal notranslate"><span class="pre">MPLSETUPCFG</span></code></a> to specify the path to a cfg file when
installing from pypi.</p>
<p>In this case, you need to install the FreeType and Qhull library and headers.
This can be achieved using a package manager, e.g. for FreeType:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span><span class="c1"># Pick ONE of the following:</span>
sudo<span class="w"> </span>apt<span class="w"> </span>install<span class="w"> </span>libfreetype6-dev<span class="w"> </span><span class="c1"># Debian/Ubuntu</span>
sudo<span class="w"> </span>dnf<span class="w"> </span>install<span class="w"> </span>freetype-devel<span class="w"> </span><span class="c1"># Fedora</span>
brew<span class="w"> </span>install<span class="w"> </span>freetype<span class="w"> </span><span class="c1"># macOS with Homebrew</span>
conda<span class="w"> </span>install<span class="w"> </span>freetype<span class="w"> </span><span class="c1"># conda, any OS</span>
</pre></div>
</div>
<p>(adapt accordingly for Qhull).</p>
<p>On Linux and macOS, it is also recommended to install <a class="reference external" href="https://www.freedesktop.org/wiki/Software/pkg-config/">pkg-config</a>, a helper
tool for locating FreeType:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span><span class="c1"># Pick ONE of the following:</span>
sudo<span class="w"> </span>apt<span class="w"> </span>install<span class="w"> </span>pkg-config<span class="w"> </span><span class="c1"># Debian/Ubuntu</span>
sudo<span class="w"> </span>dnf<span class="w"> </span>install<span class="w"> </span>pkgconf<span class="w"> </span><span class="c1"># Fedora</span>
brew<span class="w"> </span>install<span class="w"> </span>pkg-config<span class="w"> </span><span class="c1"># macOS with Homebrew</span>
conda<span class="w"> </span>install<span class="w"> </span>pkg-config<span class="w"> </span><span class="c1"># conda</span>
<span class="c1"># Or point the PKG_CONFIG environment variable to the path to pkg-config:</span>
<span class="nb">export</span><span class="w"> </span><span class="nv">PKG_CONFIG</span><span class="o">=</span>...
</pre></div>
</div>
<p>If not using pkg-config (in particular on Windows), you may need to set the
include path (to the library headers) and link path (to the libraries)
explicitly, if they are not in standard locations. This can be done using
standard environment variables -- on Linux and OSX:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span><span class="nb">export</span><span class="w"> </span><span class="nv">CFLAGS</span><span class="o">=</span><span class="s1">'-I/directory/containing/ft2build.h'</span>

built without Inkscape and optipng, but the build process will raise various
warnings. If the build process warns that you are missing fonts, make sure
your LaTeX distribution bundles cm-super or install it separately.</p>
