<p>
Csound has become a complex project and can involve many dependencies. Unless you are a Csound developer or need to develop Csound plugins,
you should try to use one of the precompiled distributions from <a class="ulink" href="http://www.sourceforge.net/projects/csound" target="_top">http://www.sourceforge.net/projects/csound</a>. However,
building from source is probably the best option on GNU/Linux.
</p>
<p>
This section focuses on the main Csound 5 build system, which uses <a class="ulink" href="http://www.scons.org" target="_top">SCons</a>, a Python program that replaces <span class="emphasis"><em>make</em></span> for cross-platform configuration and building.
</p>
<p>
When building Csound from source instead of using a precompiled package, you first need to obtain the sources for a release of Csound at <a class="ulink" href="http://www.sourceforge.net/projects/csound" target="_top">http://www.sourceforge.net/projects/csound</a>. The source packages have either a zip or tar.gz extension.
</p>
<p>
The latest (possibly unstable) Csound source code is also available through GIT. The Csound GIT front page is located at: <a class="ulink" href="http://csound.git.sourceforge.net/git/gitweb-index.cgi" target="_top">http://csound.git.sourceforge.net/git/gitweb-index.cgi</a>.
Using git for just checking out and compiling is pretty easy. Install GIT for your platform and use this command to clone the Csound5 git repository:
</p>
<pre class="programlisting">git clone git://git.code.sf.net/p/csound/csound5-git </pre>
<p>
This will checkout a read-only (meaning, you can not commit back to the central git repository) version of the Csound5 repo. To update with the latest from the master repo, use:
</p>
<pre class="programlisting">git pull</pre>
<p>
The same process is used for the Csound manual. Use this command to clone:
</p>
<pre class="programlisting">git clone git://git.code.sf.net/p/csound/manual-git </pre>
<h2><a id="idp8267984"></a>Basic requirements to build Csound 5 on any platform</h2>
<div class="itemizedlist">
<ul class="itemizedlist" type="disc">
<li class="listitem">
Install libdsndfile version 1.0.13 or later from <a class="ulink" href="http://www.mega-nerd.com/libsndfile" target="_top">www.mega-nerd.com/libsndfile</a>.
</li>
<li class="listitem">
Install Python from <a class="ulink" href="http://www.python.org" target="_top">www.python.org</a>. In most cases it is best to install the most recent stable version. Python is needed for SCons to run.
</li>
<li class="listitem">
Install the SCons build system from <a class="ulink" href="http://www.scons.org" target="_top">www.scons.org</a>.
</li>
</ul>
</div>
<p>
These are the minimum requirements for a build, but csound has many optional components which enhance functionality and add opcodes which may require additional libraries.
</p>
<h2><a id="idp8271400"></a>Optional configurations (ALL platforms)</h2>
<p>In most cases it is best to install the most recent stable versions of the optional libraries.
</p>
<div class="itemizedlist">
<ul class="itemizedlist" type="disc">
<li class="listitem">
Real-time audio can use the cross-platform PortAudio library (trunk version or devel-19 branch) from <a class="ulink" href="http://www.portaudio.com/usingcvs.html" target="_top">www.portaudio.com/usingcvs.html</a>. Please note that stable version 18 will not work. Csound can also use several platform specific audio APIs like ALSA, JACK, CoreAudio and the Windows multimedia library, see each platform notes for details.
</li>
<li class="listitem">
Real-time MIDI can use the cross-platform PortMidi library from <a class="ulink" href="http://www.cs.cmu.edu/~music/portmusic" target="_top">www.cs.cmu.edu/~music/portmusic</a>
</li>
<li class="listitem">
For GUI widgets, install FLTK 1.1 or 1.3 from <a class="ulink" href="http://www.fltk.org" target="_top">www.fltk.org</a>.
You must configure and build FLTK with <code class="literal">--enable-shared --enable-threads</code>.
</li>
<li class="listitem">
For generating Python and Java interfaces, install the Software Interface and Wrapper Generator (SWIG) from <a class="ulink" href="http://www.swig.org" target="_top">http://www.swig.org</a>.
</li>
<li class="listitem">
<span class="emphasis"><em>CsoundAC</em></span> requires FLTK and the boost C++ template libraries for random numbers and linear algebra, from <a class="ulink" href="http://www.boost.org" target="_top">http://www.boost.org</a>. <span class="emphasis"><em>CsoundAC</em></span> requires at least version 1.32.1.
</li>
<li class="listitem">The fluid opcodes require the Fluidsynth library from <a class="ulink" href="http://savannah.nongnu.org/download/fluid" target="_top">http://savannah.nongnu.org/download/fluid</a>.
</li>
<li class="listitem">
The OSC opcodes require the latest version of the liblo library from
<a class="ulink" href="http://plugin.org.uk/liblo" target="_top">http://plugin.org.uk/liblo</a>.
On Windows, liblo requires a Windows version of the POSIX thread library (pthreads) which is available from
<a class="ulink" href="http://sourceware.org/pthreads-win32" target="_top">http://sourceware.org/pthreads-win32</a>;
copy libpthreadGC2.a to libpthread.a.
You may also need the latest version of autoconf from MinGW.
</li>
<li class="listitem">
The STK opcodes require STK source code from <a class="ulink" href="http://ccrma.stanford.edu/software/stk" target="_top">http://ccrma.stanford.edu/software/stk</a>, copied into <code class="filename">csound5/Opcodes/stk</code>.
</li>
<li class="listitem">
The Loris opcodes requires Loris 1.8 to be installed: <a class="ulink" href="http://sourceforge.net/projects/loris/files" target="_top">http://sourceforge.net/projects/loris/files</a>. It will create the Csound Loris opcodes (along with Loris itself). When you run Csound use an additional command line flag: --opcode-lib. For example in Linux: --opcode-lib=/usr/local/lib/libloris.so
</li>
</ul>

<h2><a id="idp8282320"></a>Windows</h2>
<p>The following is needed to build on Windows (more complete build instructions for Windows may be found in the csound-build.tex document (csound-build.pdf)):</p>
<div class="itemizedlist">
<ul class="itemizedlist" type="disc">
<li class="listitem">
<p class="simpara">
Install a compiler like gcc or Microsoft Visual Studio (there is also support for the Intel C++ compiler). If using MinGW (gcc), install all of the current release of MinGW using the Automated MinGW Installer from <a class="ulink" href="http://www.mingw.org" target="_top">www.mingw.org</a>, for example into <code class="literal">c:/mingw</code>. This should install gcc, g++, GNU binutils, the MinGW runtime, and the win32 API. Then install the current release of MSys.
</p>
<p class="simpara">
On Windows you can use Microsoft Visual C++ (except for CsoundAC). The free Express Edition, from <a class="ulink" href="http://www.microsoft.com/express/vc/" target="_top">http://www.microsoft.com/express/vc/</a> works fine. You will need to obtain a copy of the <code class="filename">dirent.h</code> header file for Windows, e.g. from <a class="ulink" href="http://www.softagalleria.net/dirent.php" target="_top">http://www.softagalleria.net/dirent.php</a>. You may also need to obtain the <code class="literal">bufferoverflowu.lib</code> library from Microsoft and put it into the Visual C++ <code class="filename">lib</code> directory. Then open a shell in which to compile Csound, (usually called Visual Studio Command Prompt command, within the Visual C++ program menu).
</p>
</li>
</ul>
</div>
<p>Optional configurations for Windows include the following:</p>
<div class="itemizedlist">
<ul class="itemizedlist" type="disc">
<li class="listitem">
Real-time audio and MIDI can use the Windows multimedia library. This module will be built automatically if the headers are found.
</li>
<li class="listitem">
The VST Host opcodes require both the Steinberg VST headers.
</li>
</ul>
</div>
<h2><a id="idp8288568"></a>Linux</h2>
<p>Optional configurations for Linux include the following:</p>
<div class="itemizedlist">
<ul class="itemizedlist" type="disc">
<li class="listitem">
Real-time audio on Linux can use ALSA (<a class="ulink" href="http://www.alsa-project.org" target="_top">www.alsa-project.org</a>) and JACK (<a class="ulink" href="http://www.jackaudio.org/" target="_top">www.jackaudio.org/</a>) in addition to PortAudio. Distributions usually provide the appropriate dev packages for these systems through their repositories.
</li>
<li class="listitem">
The DSSI Host opcodes require both the LADSPA and DSSI headers.
</li>
</ul>
</div>
<h2><a id="idp8291048"></a>Mac OS X</h2>
<p>Optional configurations for Mac OS X include the following:</p>
<div class="itemizedlist">
<ul class="itemizedlist" type="disc">
<li class="listitem">
Real-time audio can use CoreAudio (OSX builtin native audio system) and Jack, appart from PortAudio.
</li>
<li class="listitem">
The DSSI Host opcodes require both the LADSPA and DSSI headers.
</li>
</ul>
</div>
<h2><a id="idp8292688"></a>Building Csound 5 with SCons</h2>
<p>
When you have all the necessary packages and their sources (or -dev packages) to support your particular requirements on your hardware platform, execute "scons -h" to discover the current configuration options.
</p>
<p>
Building is made considerably easier if, when installing, the downloaded headers and libraries are installed in their default locations. To modify the default build, in particular to handle non-standard options for third-party dependencies, such as where headers and libraries are to be found:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" type="disc">
<li class="listitem">
On Windows, when building with Microsoft Visual C++, modify custom-msvc.py.
</li>
<li class="listitem">
On Windows, when building with MinGW/MSys, modify custom-mingw.py
</li>
<li class="listitem">
On Mac OSX edit custom-osx.py and rename it to custom.py
</li>
<li class="listitem">
On Linux edit custom-linux-jpff.py or custom-linux-mkg.py and rename it to custom.py
</li>
</ul>
</div>
<p>
Avoid modifying the SConstruct file.
</p>
<p>Execute scons with the optional custom variables you desire. For example:</p>
<pre class="programlisting">scons buildOSC=1 buildCsound5GUI=1 buildPythonOpcodes=1 useOSC=1 builBeats=1</pre>
<div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;">

<img alt="[Note]" src="images/note.png" />
</td>
<th align="left">Note</th>
</tr>
<tr>
<td align="left" valign="top">
<p>
It is important that you set the environment variable <code class="literal">OPCODEDIR</code> to the directory where plugin libraries are installed; in the case of a double precision build, <code class="literal">OPCODEDIR64</code> should be set instead. Installers usually take care of this, but it is necessary when building from source so Csound can find its plugin libraries.
