　　gtalk基本上可以算是非常好的聊天工具了，而它是如何工作的呢？我们如何在iphone上面为自己写一个gtalk玩一下呢？这一切都是基于libjingle这个库，这个Google Talk Voice and P2P interoperability Library.libjingle这个库是一个用c++写的跨平台的库，它能很好运行在win/mac os/linux(include android)/prosix 等平台，当然也能运行在iphone平台，毕竟ios也是unix系统，但是前面的几个平台可能并不需要对libjingle库做一些程序改动就可以很好的运行了，但是ios平台却不一样，因为libjingle库中对mac os的支持代码中，有一部分代码仅仅适用于mac os,并不适用于有众多限制的ios平台，所以其实如果想移植libjingle 到ios还是需要一些改动的，在下不才，顺利完成了这次移植，希望本文能够给你带来帮助，在些感谢libjingle project owner and ilibjingle project owner:

　　一.environment setting:
　　-------------------------------------------------- -------------------------
　　 First, install Python 2.4 or later from http://www.python.org/
　　 Second ,install the stand alone scons-local package 2.0.0 or later from
　　http://www.scons.org/download.php and set an environment variable,
　　SCONS_DIR, to point to the directory containing SCons:
　　for example:
　　$vim /User/gray/.profile
　　Enter the following content: #set env of SCONS_DIR export SCONS_DIR=/Users/anson/Documents/work/scons-local- 2.0.1/scons-local-2.0.1/  $sourece /User/gray/.profile  Third, install swtoolkit from http://code.google.com/p/swtoolkit/. We just download it into a place(eg:/User/gray/..../swtoolkit), It's  a green tool. Finally, Libjingle depends on 3 open-source projects, expat , srtp and openssl. Download expat from http://sourceforge.net/projects/expat/ to     talk/third_party/expat-2.0.1/.  Download srtp from http://libjingle.googlecode.com/files/srtp-cvs.zip to     talk/third_party/srtp/.  note:Don't download srtp from it's official website.only one google version can work for libjingle  Download openssl source code to     talk/third_party/openssl-1.0.0. 二. Modify Build Parameters  -------------------------------------------------- ------------------------- 1.Modify  main.scons  [iphone Simulator]: (1) Change '-isysroot', '/Developer/SDKs/MacOSX10.5.sdk', to  '-isysroot', '/Developer/Platforms/iPhoneSimulator.platform/Dev eloper/SDKs/iPhoneSimulator3.1.2.sdk', (2)Add the following content into # M A C OSX Block mac_env.Replace(CC = '/Developer/Platforms/iPhoneSimulator.platform/Dev eloper/usr/bin/gcc-4.2') mac_env.Replace(CXX = '/Developer/Platforms/iPhoneSimulator.platform/Dev eloper/usr/bin/g++-4.2') (3)Add 'CoreAudio', 'QuickTime', 'Cocoa', and 'QTKit' to the FRAMEWORKS variable.  [iphone Device]: (1) Change '-isysroot', '/Developer/SDKs/MacOSX10.5.sdk', to      '-isysroot', '/Developer/Platforms/iPhoneOS.platform/Developer/ SDKs/iPhoneOS3.1.2.sdk', (2)Add the following content into # M A C OSX Block mac_env.Replace(CC='/Developer/Platforms/iPhoneOS. platform/Developer/usr/bin/gcc-4.2') mac_env.Replace(CXX='/Developer/Platforms/iPhoneOS .platform/Developer/usr/bin/g++-4.2') (3)Add 'CoreAudio', 'QuickTime', 'Cocoa', and 'QTKit' to the FRAMEWORKS variable. 2.Modify libjingle.scons (1)Comment out some files with "#",because IOS SDK is limited ,So some api is unsupport by IOS: #"base/macutils.cc", #               "session/phone/devicemanager_mac.mm", #               "base/proxydetect.cc", (2)Add some Header serach directory in includedirs. like: "third_party/openssl-1.0.0/include", 三.Building libjingle: -------------------------------------------------- ------------------------- 》》》How to build libjingle for iphone Simulator

　　$ ./configure
　　3. 
　　$ cd libjingle-0.5/talk/third_party/openssl-1.0.0 
　　$ ./config no-shared no-asm 
　　4. 
　　Build or Download openssl lib(libcrypto.a,libssl.a) for iphonesimulator to talk/build/dbg/lib
　　5.$/User/gray/..../swtoolkit/hammer.sh

　　四.Modify libjingle source code
　　-------------------------------------------------- -------------------------
　　Refrence : http://code.google.com/p/ilibjingle/
　　五.XCode setting
　　You can refrence  http://code.google.com/p/ilibjingle/
　　1.Add libjingle.a path in Library Search Paths
　　2.Add some Header path in Header Search Paths
　　like:
　　/..../talk/third_party/srtp/crypto/include/ 
　　/..../talk/third_party/srtp/include/ 
　　/..../talk/third_party/expat-2.0.1/ 
　　/..../talk/third_party/openssl-1.0.0/include/

　　3.GCC_PREPROCESSOR_DEFINITIONS:
　　POSIX xOSX_USE_COCOA HAMMER_TIME=1 LOGGING=1 FEATURE_ENABLE_SSL FEATURE_ENABLE_VOICEMAIL FEATURE_ENABLE_PSTN HASHNAMESPACE=__gnu_cxx DISABLE_DYNAMIC_CAST HAVE_OPENSSL_SSL_H=1 OS_MACOSX=OS_MACOSX OSX _DEBUG FLAVOR_DBG ENABLE_DEBUG FEATURE_ENABLE_VOICEMAIL EXPAT_RELATIVE_PATH SRTP_RELATIVE_PATH XML_STATIC HAVE_EXPAT_CONFIG_H MAC_OS_X_VERSION_MIN_REQUIRED=1040
