Ubuntu 12.04

1. sudo apt-get install git-core build-essential cmake libxml2-dev libcurl4-openssl-dev
2. git clone git://github.com/bitmovin/libdash.git
3. cd libdash/libdash
4. mkdir build
5. cd build
6. cmake ../
7. make
8. cd bin
9. The library and a simple test of the network part of the library should be available now. You can test the network part of the library with
10. ./libdash_networkpart_test
