I am trying to install NS-3.25 on Ubuntu 16.04.
Building gccxml-ns3 - Problem
> Problem: Optional dependency, module "gccxml-ns3" failed
This may reduce the functionality of the final build.
However, bake will continue since "gccxml-ns3" is not an essential dependency.
For more information call bake with -v or -vvv, for full verbose mode.

Thanks in advance.
