How to build libjingle for iphone iPhone OS platform and iPhone Simulator platform ? #111

How to build libjingle for iphone iPhone OS platform and iPhone Simulator 
platform ?

because  the iPhone  SDK is limited ,so many api that is not aviable in iphone 
sdk, so porting to iphone platform is not so easy. I think there are 3 methods 
to port libjingle into iphone platform.

1.Use posix platform  instead of  mac pkatform (eg:mac_src => posix_src).

2.Another way is to Comment out the code that  isn't be supported in iphone SDK.

3.The 3th method is best , redefined the functions for iphone platform.

 ciwavinc selected the 2th way to port ,the project  is http://code.google.com/p/ilibjingle/
but i think it's not  good for iphone.so If somebody can give me some suggest?

一.environment setting:
---------------------------------------------------------------------------
<1> First, install Python 2.4 or later from http://www.python.org/

<2> 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

<3> 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.

<4>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/Developer/SDKs/iPhoneSimulator3.1.2.sdk',

(2)Add the following content into # M A C OSX Block

mac_env.Replace(CC = 
'/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2')
mac_env.Replace(CXX = 
'/Developer/Platforms/iPhoneSimulator.platform/Developer/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.

(4)Change ['-arch','i386'] to  ['-arch', 'armv6'] in mac env setting,

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",

I've followed the directions outlined by quohui, and am getting errors 
throughout the build process. 

1. 
$ cd libjingle-0.5/talk/third_party/srtp
$ ./configure

checking size of unsigned long... configure: error: cannot compute sizeof 
(unsigned long), 77

<ignored the compute sizeof error>

Several problems with the hammer build:

I think the problem is this, note that I used "./config no-shared no-asm" to 
build openssl

ld: warning: ignoring file 
/Users/mitchellru/ilibjingle/ilibjingle/gtalk/libjingle-0.5/talk/third_party/ope
nssl-1.0.0/libcrypto.1.0.0.dylib, file was built for unsupported file format 
which is not the architecture being linked (armv6)
