<h1 id="building-cinder">Building Cinder</h1>
64+
<h3 id="fetching-and-building-cinder">Fetching and Building Cinder</h3>
65+
<pre><code>git clone --recursive https://github.com/cinder/Cinder.git
66+
cd Cinder
67+
mkdir build &amp;&amp; cd build
68+
cmake .. -DCINDER_TARGET_GL=es3-rpi
69+
make -j 3
70+
</code></pre>
71+
72+
<p>NOTE: Attempting to build Cinder with more than 3 jobs (specified with the <code>-j 3</code> parameter) will likely cause a hard crash due to GCC memory requirements.</p>
73+
74+
<h4 id="clang">Clang</h4>
75+
<p>Cinder can also be used with the version of Clang (v3.5.0) packaged for Raspbian Jessie. Install it using <code>apt-get</code>:</p>
76+
<pre><code>sudo apt-get install clang</code></pre>
77+
<p>To set Clang as the default compiler, select <code>/usr/bin/clang++</code> when prompted by this command:
78+
<pre><code>sudo update-alternatives --config c++</code></pre>
79+
</p>
80+
81+
<h1 id="building-and-running-basicapp">Building and Running BasicApp</h1>
82+
<h3 id="building">Building</h3>
83+
<pre><code>cd samples/BasicApp/proj/cmake
84+
mkdir build &amp;&amp; cd build
85+
cmake .. -DCINDER_TARGET_GL=es3-rpi
86+
make</code></pre>
87+
88+
<h3 id="running">Running</h3>
89+
<p>Starting from <code>samples/BasicApp/proj/cmake/build</code>:</p>
90+
<pre><code>./Debug/BasicApp</code></pre>
91+
92+
<h3 id="exiting">Exiting</h3>
93+
<p>Hit the <code>Esc</code> key to exit the BasicApp. Cinder for Linux on the Raspberry Pi 3 currently has <code>Esc</code> hardcoded to exit an application. Otherwise it's non-trivial to return to the OS. A future version will offer a more graceful way to handle this.</p>
94+
<h1 id="troubleshooting">Troubleshooting</h1>
95+
<h3 id="audio">Audio</h3>
96+
97+
<h4 id="context_create_failed">Starting the pulsedeamon</h4>
98+
<p>Raspbian ships with Pulse Audio installed, however you must start the <code>pulsedeamon</code> before you can use audio in your application. Do that by running the following:</p>
99+
<pre><code>pulseaudio -D</code></pre>
100+
101+
<h4 id="no-output-using-35-jack">No Output Using 3.5mm headphone jack</h4>
102+
<p>Try the following, it will force output to the 3.5mm jack (<a href="https://www.raspberrypi.org/documentation/configuration/audio-config.md">more information here</a>):</p>
103+
<pre><code>sudo amixer cset numid=3 1</code></pre>
