[Ndn-interest] How to develop & run an appplication program on NDNx ?

[Burke, Jeff]

Hi Daiki,

Thanks for your interest!

There are a few different libraries for NDN development right now:

Included in the NDNx package are a C library and Java library, which are
older and do not follow the CCL API.  These are based on the original CCNx
libraries (of which NDNx is a fork) and will be deprecated. However, you
could use these for application development of simple applications - and
the apps in the NDNx distribution use them.

The NDN-CCL is an emerging set of libraries for general purpose
application development that have the advantage of being largely wire
format independent but simpler than the NDNx Java library. They will be
supported into the future as the codebase evolves.  There is a C++
library, a Python library, and a Javascript library, referred to here:
	http://named-data.net/codebase/platform/
For the CCL, we also have a preliminary but incomplete Java library -
https://github.com/named-data/jndn.

All of the libraries (NDNx C and Java, NDN-CCL C++, Javascript, Python and
eventually Java) work with the NDNx forwarder (ndnd).  So you can take
your pick.  There are also other libraries that we use for development,
but I would stick with these for simplicity.  Example code for serving
files can be found in these projects: https://github.com/named-data/NDNFS
 and  https://github.com/named-data/ChronoShare.

I hope this helps. Please let us know more about your language preferences
and we can point you to some good starting places.

Jeff
