1.安装预备
检出代码 git clone git://git.linphone.org/linphone-iphone.git --recursive
下载 MacPorts http://www.macports.org/install.php
Mountain Lion版本 https://distfiles.macports.org/MacPorts/MacPorts-2.2.0-10.8-MountainLion.pkg
2.依照检出代码 README提示步骤，进行相关编译/安装
首先搞定PATH配置，使用了zsh，如下操作
添加/opt/local/bin
echo "export PATH=$PATH" >> ~/.zshrc
source ~/.zshrc
#确认安装Xcode以及Macports
sudo port install coreutils automake autoconf libtool intltool wget pkgconfig cmake gmake yasm grep doxygen ImageMagick optipng antlr3
时间超长 中间看看是否有failed的情况，剩下的就是等了
如果是失败，看看是什么问题，要是超时的话，从中断的地方继续下载。
#Install gas-preprosessor.pl version above Jully 2013
$ wget --no-check-certificate https://raw.github.com/yuvi/gas-preprocessor/master/gas-preprocessor.pl
超时？ 直接去网站下吧
$ sudo mv gas-preprocessor.pl /opt/local/bin/.
$ sudo chmod +x /opt/local/bin/gas-preprocessor.pl
#Link macport libtoolize to glibtoolize
$ sudo ln -s /opt/local/bin/glibtoolize /opt/local/bin/libtoolize
#Link host's strings to simulator SDK
For Xcode prior to 4.3:
$ sudo ln -s /usr/bin/strings /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/strings
For newer XCode:
$ sudo ln -s /usr/bin/strings /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/strings
BUILDING THE SDK
****************
* GPL third parties versus non GPL third parties
This sdk can be generated in 2 flavors. Firt is with GPL third parties, it means liblinphone includes GPL third parties like FFMPEG or x264.
If you choose this flavor, your final application must comply with GPL in any case. This is the default mode.
To generate the liblinphone multi arch sdk in GPL mode, do:
$ cd submodules/build
$ make all
*需要联网
*花费1小时
The resulting sdk is in liblinphone-sdk/ directory.
