Erizo is an MCU that is part of the licode stack. It is written in C++ and a node API is provided, so I personally find that pretty exciting.
To build erizo you are going to need both cmake and various boost libaries. These can be installed on a debian based system with the following command:
sudo apt-get install cmake libboost-dev libboost-system-dev libboost-thread-dev libboost-regex-dev libnice-dev
Once you have the prereqs installed, you can then clone the licode repository:
git clone git://github.com/ging/lynckia.git
While the repository provides some helper scripts, I prefer to change into the erizo directory and compile from there:
./generateProject.sh
All being well you should see output similar to the following:
current source dir /home/doehlman/code/github/lynckia/erizo/src/erizo
-- Found glib-2.0: /usr/include/glib-2.0, /usr/lib/x86_64-linux-gnu/libglib-2.0.so;/usr/lib/x86_64-linux-gnu/libgobject-2.0.so;/usr/lib/x86_64-linux-gnu/libgthread-2.0.so

Done
Now that cmake has done it's thing preparing the project, you should now be able to build:
cd build
make
If built successfully, you should now have a shiny new liberizo.so in the erizo/build/erizo/ directory.
With the erizo library built, you should now be able to build the node wrapper. To do this, head back to the main directory of the licode repository and chdir to the erizoAPI directory:
cd erizoAPI
If you have a version of node installed, you should now be able to use node-waf to configure and build the module:
ERIZO_HOME=~/code/github/lynckia/erizo node-waf configure build
The above command sets the ERIZO_HOME environment variable for the duration of the build process. You should change this to suit your own pathing preferences (noting that the path must be absolute).
