freeswitch安装过程（Ubuntu）

系统：
Ubuntu 14.04 64位

源码下载：
git clone https://freeswitch.org/stash/scm/fs/freeswitch.git

依赖包安装：
libedit-dev libldns-dev
libpcre3-dev libspeexdsp-dev libspeex-dev libcurl4-openssl-dev libopus-dev
libncurses5-dev libtiff-dev libjpeg-dev zlib1g-dev libssl-dev libsqlite3-dev
build-essential automake autoconf git-core wget libtool
liblua50-dev libsndfile1-dev

还有ubuntu官方源中缺少的几个软件包：
1.下载libyuv源码并编译

cd freeswitch/dep-libs
git clone https://freeswitch.org/stash/scm/sd/libyuv.git
cd libyuv
make -f linux.mk CXXFLAGS="-fPIC -O2 -fomit-frame-pointer -Iinclude/"
make install

2.下载yasm并编译

yasm是一个汇编编译器，是nasm的升级版
yasm下载地址：http://www.tortall.net/projects/yasm/releases/
yasm解压命令：tar -zxvf ****.tar.gz （我下载的是yasm-1.3.0.tar.gz）
yasm编译安装：① ./configure， ② make, ③ make install
yasm安装完毕之后回到第二步重新安装libvpx

3.下载libvpx源码并编译

git clone https://freeswitch.org/stash/scm/sd/libvpx.git
cd libvpx
./configure --enable-pic --disable-static --enable-shared
make install

4.下载opus并编译

git clone https://freeswitch.org/stash/scm/sd/opus.git
cd opus
./autogen.sh
./configure
make
make install

5.下载libpng并编译

git clone https://freeswitch.org/stash/scm/sd/libpng.git
cd libpng
./configure
make
make install

6.下载libsilk并编译

git clone https://freeswitch.org/stash/scm/sd/libsilk.git
cd libsilk
./configure
make
make install

安装过程：
ldconfig 确保上面安装的第三方库都能够被正确链接
./configure
make
make install

安装语音包（英文)
make sounds-install
make moh-install

安装silk解码器
make mod_silk-install
