[ndnSIM] Is the version 2.0 really stable? Is it encouraged to upgrade to version 2.0?

Tue Feb 17 11:22:31 PST 2015

Hello,

I installed the simulator yesterday evening in my machine with the latest commits for ndn-cxx and ndnSIM and I did not have any problems (OS X 10.10.2).
To my best knowledge, there are no stability issues. The code is stable and the instructions online are accurate.

For the specific commit that you are talking about, you can take a look here:

http://gerrit.named-data.net/#/c/1765/
http://jenkins.named-data.net/job/ndnSIM/37/

ndnSIM compiled successfully to all the platforms with the latest commits for both ndn-cxx and ndnSIM.

Please let me know about the operating system that you are using and make sure that you do not have multiple versions of ndn-cxx installed, so that a previous version is possibly used.
