Debugging</h1>
<p>If you are having problems getting <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> to run on your system, make sure to pass a value of <em>true</em> to the <a class="el" href="classRtAudio.html#af0752ee51cce3dd90a3bd009f9fdbe77" title="Specify whether warning messages should be printed to stderr.">RtAudio::showWarnings()</a> function (this is the default setting). A variety of warning messages will be displayed which may help in determining the problem. Also, try using the programs included in the <code>tests</code> directory. The program <code>audioprobe</code> displays the queried capabilities of all hardware devices found for all APIs compiled. When using the ALSA and JACK APIs, further information can be displayed by defining the preprocessor definition <b>RTAUDIO_DEBUG</b>.</p>

Compiling</h1>
<p>In order to compile <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> for a specific OS and audio API, it is necessary to supply the appropriate preprocessor definition and library within the compiler statement: </p>

<p>The example compiler statements above could be used to compile the <code>audioprobe.cpp</code> example file, assuming that <code>audioprobe.cpp</code>, <code><a class="el" href="RtAudio_8h.html">RtAudio.h</a></code>, <code><a class="el" href="RtError_8h_source.html">RtError.h</a></code>, and <code>RtAudio.cpp</code> all exist in the same directory. </p>
