[Ndn-interest] NLSR and ndn-cxx : Compiler version?

[Divyashri Bhat]

Hi Davide, Junxiao,

Thank you for getting back to me so quickly!

I tried installing ndn-cxx, NFD and NLSR on a new VM and this time it was successful. On my previous installation I wrongly assumed I had to update the gcc because of an error message I saw in build/config.log of NLSR that said something like "g++: error: unrecognized command line option ‘-std=c++11’”

The problem is now solved with a fresh installation. Turns out I did not have to update the gcc after all!

Thanks!
