It is a svn diff result, not a patch, actually.

So, what is Libjingle? Quoted from http://code.google.com/p/libjingle/:

Libjingle, the Google Talk Voice and P2P Interoperability Library, is a set of components we provide to interoperate with Google Talk's peer-to-peer file sharing and voice calling capabilities. The package includes source code for Google's implementation of Jingle and Jingle-Audio, two proposed extensions to the XMPP standard that are currently available in draft form.

You can check out the head revision of Libjingle from its svn repository using command:

svn checkout http://libjingle.googlecode.com/svn/trunk/ libjingle-read-only

Then ``./autogen.sh'' and ``make'' as we usually do for building a *nix software. You will find many errors during ``./autogen.sh'' and ``make''. To fix them, first, some LIBs should be installed:

sudo apt-get install build-essential libexpat1-dev libglib2.0-dev libogg-dev libssl-dev libasound2-dev libspeex-dev openssl libortp7-dev libmediastreamer0-dev libavcodec-dev

I am not very sure if these LIBs are enough. If you have some problem with this, please let me know.

Even if you have all of these LIBs installed, you will still get some errors such as:

../../talk/base/stringutils.h:272: error: extra qualification 'talk_base::Traits::' on member 'empty_str'
../../talk/base/base64.h:26: error: extra qualification ‘talk_base::Base64::’ on member ‘Base64Table’
../../talk/base/base64.h:27: error: extra qualification ‘talk_base::Base64::’ on member ‘DecodeTable’

So here is a patch for source code errors like this. IMPORTANT NOTE: gcc version 4.2.4 on Ubuntu 8.04, libortp7.

You killed all these errors? Congratulations! You can start talking with your gtalk friends with command ``call'' in talk/examples/call/ !

PS: If you are working with GCC 4.3.x, more strict checking is applied on the code. However, most errors can be fixed by adding some C headers into the #include fields, such as: <cstdlib>, <cstring>.
