[Ndn-interest] Our Discussion over the Phone - Obuntu Mate and NFD

Thu Apr 4 20:43:53 PDT 2019

I guess your ndn-cxx is not the latest one. Recently, some change has been made in the scheduler (https://github.com/named-data/ndn-cxx/commit/a5f233e103453f6157715b0cec0997658c4ec075). I suggest you to compile the latest ndn-cxx and retry.

Saurab,

Either try with python2.7:
CXX=clang++-3.9 python2.7 ./waf configure
python2.7 ./waf
sudo python2.7 ./waf install

or

uninstall sphinx (not necessary for compilation - only if you want to generate the documentation website like: https://named-data.net/doc/ndn-cxx/current/) and then configure, compile, and install again.

The easiest way that I know of to install ndn-cxx and NFD on the Pi is from source on raspbian OS using clang (not the default gcc as it requires extending swap and is up to 10 times slower). Example:
sudo apt install clang-3.9
CXX=clang++-3.9 ./waf configure
(please see: https://named-data.net/doc/ndn-cxx/current/INSTALL.html#customizing-the-compiler)
(other instructions are same for ndn-cxx and NFD).

Another option is cross-compiling (outdated - but steps should be similar):

Hi Prof. Mohan,

It was nice to talk to you.  I’m cc’ing Ashlesh Gawande who can answer Ahmed’s questions about the installation.  In addition, there is an ndn-interest mailing list he can jin to ask such questions (https://www.lists.cs.ucla.edu/mailman/listinfo/ndn-interest).

Dear Professor Wang,

It was my pleasure talking to you over the phone just now. As I explained to you over the phone, Ahmed Awad is my doctoral student working on a research problem in the area of connected vehicles.  He has been trying to install NFD on raspberry pi 3 with Rasbian or Ubuntu mate or Ubuntu server without success. If you  could provide Ahmed with a contact who could help him as well as any documentation you can provide, that will be very much appreciated.

Again, thank you for your help.
