Steps to Reproduce the Problem

1. clone this repository inside the src directory 2../waf configure --enable-tests --enable-examples 3../waf build

when I use branch gh-pages, I can success. But the gh-pages version is too old, and I want to use the newer version

Can you try compiling on ns-3.29 or ns-3.30?

[ypwang36]

thanks！ I compiled successful in ns-3.30!
