Libjingle Libjingle is a set of components provided by Google to interoperate with Google Talk's peer-to-peer and voice capabilities. This package will create several static libraries you may link to your project as needed. -talk - No source files in talk/, just these subdirectories |-base - Contains basic low-level portable utility functions for | things like threads and sockets |-p2p - The P2P stack |-base - Base p2p functionality |-client - Hooks to tie it into XMPP |-session - Signaling |-phone - Signaling code specific to making phone calls |-third_party - Components that aren't ours |-mediastreamer - Media components for dealing with sound hardware and | voice codecs |-xmllite - XML parser |-xmpp - XMPP engine In addition, this package contains two examples in talk/examples which illustrate the basic concepts of how the provided classes work. The xmllite component of libjingle depends on expat. You can download expat from http://expat.sourceforge.net/. mediastreamer, the media components used by the example applications depend on the oRTP and iLBC components from linphone, which can be found at http://www.linphone.org. Linphone, in turn depends on GLib, which can be found at http://www.gtk.org. This GLib dependency should be removed in future releases. Building Libjingle Once the dependencies are installed, run ./configure. ./configure will return an error if it failed to locate the proper dependencies. If ./configure succeeds, run 'make' to build the components and examples. When the build is complete, you can run the call example from talk/examples/call and the pcp example from talk/examples/pcp. Relay Server Libjingle will also build a relay server that may be used to relay traffic when a direct peer-to-peer connection could not be established. The relay server will build in talk/p2p/base/relayserver and will listen on UDP ports 5000 and 5001. See the Libjingle Developer Guide at http://code.google.com/apis/talk/index.html for information about configuring a client to use this relay server. STUN Server Lastly, Libjingle builds a STUN server which implements the STUN protocol for Simple Traversal of UDP over NAT. The STUN server is built as talk/p2p/base/stunserver and listens on UDP port 7000. See the Libjingle Developer Guide at http://code.google.com/apis/talk/index.html for information about configuring a client to use this STUN server.
