I am installing iTetris by following the guidelines (downloaded a week ago) at this site, but I got stuck at ns3 installation. Merely:

- iCS installed succesfully
- ns3 throws an error when entering the command:
sudo ./waf install

The error is as follows:


+ install /usr/local/include/ns3.18.1/ns3/internet-module.h (from build/ns3/internet-module.h)
+ install /usr/local/include/ns3.18.1/ns3/lte-module.h (from build/ns3/lte-module.h)
Waf: Leaving directory `/home/jesus-it/Desktop/iTetris/ns-3/ns-allinone-3.18.2/ns-3.18.1/build’

{task 52788176: inst ns3.18.1-emu-sock-creator-optimized -> })


Other data that may be related:
- the error always prompts at the installation of the lte-module.h or at the internet-module.h
- ns3 version 3.18
- Ubuntu 12.04 LTS (64 bits)

Finally, I can install ns3 by substituting the command “sudo ./waf install” by “sudo ./waf” and the “missing node signature error” does not appear (this is the only change that I have made with respect with the guidelines). However, by doing this I cannot find later the libns3.so in my system (not under the folder /usr/local/lib/ nor in the entire system)

Is there anyone who got iTetris working in Ubuntu 12.04 by following the guidelines? Could you help me with this?

Thanks in advance,
