<h2>
Compiling for Windows (WMME or DirectSound)</h2>
<blockquote>To compile PortAudio for Windows, you can choose between two
options. One implementation uses the DirectSound API. The other uses the
Windows MultiMedia Extensions API (aka WMME or WAVE).
<p>Some advantages of using DirectSound are that DirectSound may have lower
latency than WMME, and supports effects processing plugins. But one disadvantage
is that DirectSound is not installed on all PCs, and is not well supported
under Windows NT. So WMME is the best choice for most projects.
<p>For either implementation add the following source files to your project:
<blockquote>
<pre><b>pa_common\pa_lib.c
pa_common\portaudio.h
pa_common\pa_host.h</b></pre>
</blockquote>
Link with the system library "<b>winmm.lib</b>". For Visual C++:
<ol>
<li>
select "Settings..." from the "Project" menu,</li>
<li>
select the project name in the tree on the left,</li>
<li>
choose "All Configurations" in the popup menu above the tree,</li>
<li>
select the "Link" tab,</li>
<li>
enter "winmm.lib", without quotes, as the first item in the "Object/library
modules:" field.</li>
</ol>
<b>WMME</b> - To use the WMME implementation, add the following source
files to your project:
<blockquote><b><tt>pa_win_wmme/pa_win_wmme.c</tt></b></blockquote>
<b>DirectSound</b> - If you want to use the DirectSound implementation
of PortAudio then you must have a recent copy of the free
<a href="http://www.microsoft.com/directx/download.asp">DirectX</a>
SDK for Developers from Microsoft installed on your computer. To compile
an application add the following source files to your project:
<blockquote>
<pre><b>pa_win_ds\dsound_wrapper.c
pa_win_ds\pa_dsound.c</b></pre>
</blockquote>
Link with the system library "<b>dsound.lib</b>" using the procedure described
above for "winmm.lib".</blockquote>
<blockquote>You might try compiling the "pa_tests\patest_saw.c" file first
because it is the simplest.</blockquote>
