I did following to build libjingle :

Building LibJingle for Linux

1. How to Build

Libjingle is built with swtoolkit ( http://code.google.com/p/swtoolkit/), which is a set of extensions to the open-source SCons build tool ( http://www.scons.org).

• First, install Python 2.4 or later from http://www.python.org/. Please note that since swtoolkit only works with Python 2.x, you will not be able to use Python 3.x.

• 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, /src/libjingle/scons-local/scons-local-2.0.0.final.0/.

• Third, install swtoolkit from http://code.google.com/p/swtoolkit/.

• Finally, Libjingle depends on two open-source projects, expat and srtp. Download expat from http://sourceforge.net/projects/expat/ to talk/third_party/expat-2.0.1/. Follow the instructions at http://sourceforge.net/projects/srtp/develop to download latest srtp to talk/third_party/srtp. Note that srtp-1.4.4 does not work since it misses the extensions used by Libjingle. If you put expat or srtp in a different directory, you need to edit talk/libjingle.scons correspondingly.

2.1 Build Libjingle under Linux or OS X

• First, make sure the SCONS_DIR environment variable is set correctly.
• Second, run talk/third_party/expat-2.0.1/configure and talk/third_party/srtp/configure.
• Third, go to the talk/ directory and run $path_to_swtoolkit/hammer.sh. Run $path_to_swtoolkit/hammer.sh --help for information on how to build for different modes.

Other than above given steps, See following as reference

Set SCONS_DIR Path

export SCONS_DIR=/home/esumit/libjingle/libjingle-0.5.2/talk/third_party/scons-local/scons-local-2.0.1

Install libasound2-dev Lib to compile libJingle, otherwise you will encounter errors.

sudo apt-get install libasound2-dev

Download SRTP using the following command. If it asks for a passowrd, just hit Enter.

cvs -z3 -d:pserver:anonymous@srtp.cvs.sourceforge.net:/cvsroot/srtp co -P srtp

Possible components in LibJingle Directory

libjingle-0.5.2/talk/third_party$ ls
expat-2.0.1  libudev  scons-local  srtp  swtoolkit

Execute following command to build LibJingle

libjingle-0.5.2/talk$ ./third_party/swtoolkit/hammer.sh
