#summary Building Source v2.0
#labels Featured,Phase-Deploy

This section explains how to build the project using *CentOS 64* but could be easily adapted for any _Linux_, _Windows_ or _OS X_.<br />

<wiki:toc max_depth="3" />


==Preparing the system==
{{{
sudo yum update
sudo yum install make libtool autoconf subversion git wget libogg-devel gcc gcc-c++
}}}

The first step is to checkout Doubango 2.0 source code:
{{{
svn checkout http://doubango.googlecode.com/svn/branches/2.0/doubango doubango
}}}

===Building libsrtp===
libsrtp is required.
{{{
git clone https://github.com/cisco/libsrtp/
cd libsrtp
CFLAGS="-fPIC" ./configure --enable-pic && make && make install
}}}

===Building OpenSSL===
*OpenSSL* is required if you want to use the _RTCWeb Breaker_ module or Secure WebSocket transport (WSS). *OpenSSL version _1.0.1_ is required if you want support for _DTLS-SRTP_*.<br />
This section is only required if you don’t have _OpenSSL_ installed on your system or using version prior to _1.0.1_ and want to enable _DTLS-SRTP_.<br />
A quick way to have _OpenSSL_ may be installing *openssl-devel* package but this version will most likely be outdated (prior to _1.0.1_). Anyway, you can check the version like this: 
{{{ 
openssl version 
}}}
To build OpenSSL:
{{{
wget http://www.openssl.org/source/openssl-1.0.1c.tar.gz
tar -xvzf openssl-1.0.1c.tar.gz
cd openssl-1.0.1c
./config shared --prefix=/usr/local --openssldir=/usr/local/openssl && make && make install
}}}

===Building libspeex and libspeexdsp===
*libspeex* (audio codec) an *libspeexdsp* (audio processing and jitter buffer) are optional. It’s highly recommended to enable libspeexdsp.
{{{
wget http://downloads.xiph.org/releases/speex/speex-1.2beta3.tar.gz
tar -xvzf speex-1.2beta3.tar.gz
cd speex-1.2beta3
./configure --disable-oggtest && make && make install
}}}

===Building YASM===
*YASM* is only required if you want to enable *VPX* (VP8 video codec) or *x264* (H.264 codec).
{{{
wget http://www.tortall.net/projects/yasm/releases/yasm-1.2.0.tar.gz
tar -xvzf yasm-1.2.0.tar.gz
cd yasm-1.2.0
./configure && make && make install
}}}

===Building libvpx===
_Date: December 1, 2012_ <br />
*libvpx* adds support for *VP8* and is optional but highly recommended if you want support for video when using Google Chrome or Mozilla Firefox.
{{{
git clone http://git.chromium.org/webm/libvpx.git
cd libvpx
./configure --enable-realtime-only --enable-error-concealment --disable-examples --enable-vp8 --enable-pic --enable-shared --as=yasm
make && make install
}}}

===Building libyuv===
*libyuv* is optional. Adds support for video scaling and chroma conversion.
{{{
mkdir libyuv && cd libyuv
svn co http://src.chromium.org/svn/trunk/tools/depot_tools . 
./gclient config http://libyuv.googlecode.com/svn/trunk
./gclient sync && cd trunk
make -j6 V=1 -r libyuv BUILDTYPE=Release
#cp out/Release/obj.target/libyuv.a /usr/local/lib
#mkdir /usr/local/include/libyuv && cp -r include/* /usr/local/include/libyuv
}}}

===Building libopus===
*libopus* is optional but highly recommended as it’s an MTI codec for WebRTC. Adds support for [http://www.opus-codec.org/ Opus audio codec].
{{{
wget http://downloads.xiph.org/releases/opus/opus-1.0.2.tar.gz
tar -xvzf opus-1.0.2.tar.gz
cd opus-1.0.2
./configure --with-pic --enable-float-approx && make && make install
}}}

===Building opencore-amr===
*opencore-amr* is optional. Adds support for *AMR* audio codec.
{{{
git clone git://opencore-amr.git.sourceforge.net/gitroot/opencore-amr/opencore-amr
autoreconf --install && ./configure && make && make install
}}}

===Building libgsm===
*libgsm* is optional. Adds support for *GSM* audio codec.
{{{
wget http://www.quut.com/gsm/gsm-1.0.13.tar.gz
tar -xvzf gsm-1.0.13.tar.gz
cd gsm-1.0-pl13 && make && make install
#cp -rf ./inc/* /usr/local/include
#cp -rf ./lib/* /usr/local/lib
}}}

===Building g729===
*G729* is optional. Adds support for *G.729* audio codec.
{{{
svn co http://g729.googlecode.com/svn/trunk/ g729b
cd g729b
./autogen.sh && ./configure --enable-static --disable-shared && make && make install
}}}

===Building iLBC===
*iLBC* is optional. Adds support for *iLBC* audio codec.
{{{
svn co http://doubango.googlecode.com/svn/branches/2.0/doubango/thirdparties/scripts/ilbc
cd ilbc
wget http://www.ietf.org/rfc/rfc3951.txt
awk -f extract.awk rfc3951.txt
./autogen.sh && ./configure
make && make install
}}}

===Building x264===
_Date: December 2, 2012_ <br />
*x264* is optional and adds support for *H.264* video codec (requires FFmpeg).
{{{
wget ftp://ftp.videolan.org/pub/x264/snapshots/last_x264.tar.bz2
tar -xvjf last_x264.tar.bz2
# the output directory may be difference depending on the version and date
cd x264-snapshot-20121201-2245
./configure --enable-static --enable-pic && make && make install
}}}

===Building FFmpeg===
_Date: December 2, 2012_ <br />
*FFmpeg* is optional and adds support for *H.263*, *H.264* (requires *x264*) and *MP4V-ES* video codecs.
{{{
git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg
cd ffmpeg
# grap a release branch
