# Intro

[Click](http://read.cs.ucla.edu/click/) is a modular router library developed at [UCLA](http://read.cs.ucla.edu/), allowing Click-definied router networks to be ‘attached’ to an ns-3- nodes layer 3 functionality. It has very little relevance to my own research, but was interesting to play with.

In a nutshell, [Click](http://pdos.csail.mit.edu/papers/click:tocs00/paper.pdf) is an extention to the linux kernel that provides a highly performant and configurable routing architecture.

Requirements

- Already installed ns-3
- git
- ~/src directory

# Get ’er dun

`cd ~/src; git clone git://read.cs.ucla.edu/git/click ; cd click` `sudo ./configure --enable-nsclick --enable-userlevel; sudo make; sudo make install`

*Sudo ./configure is required to grant access to some root-only areas of the kernel tree*

This should install everything under /usr/local/include/click, but leaves the shared library files in the src dir (This tripped me up a bit…)

`cd ~/src/<ns3-working-dir>/`

./waf distclean

`./waf --enable-nsclick=~/src/click --enable-examples` $(plus whatever additional clauses you use, I like `--visualize --enable-mpi --enable-tests --enable-sudo`)

`./waf --run nsclick-simple-lan`

Jobs a good one
