<div>Hi Peter,<br>
<br>
Generally speaking, if you build the master branch of ndn-tools from<br>
git, you need to use the master branch of ndn-cxx as well. There is no<br>
guarantee that it will work with an earlier release. If you prefer to<br>
use the official release, ndn-tools-0.5 should work with ndn-cxx-0.6.<br>
<br>
Note that you can use ./waf configure --enable-dump to build only ndndump.<br>
<br>
Best,<br>
Davide<br>
