[Nfd-dev] NLSR failed to connect with NFD in Banana Pro (Raspbian OS)

Thank you for finding this potentially related issue.  Not knowing how ndn-cxx works internally, I wonder why the face creation would fail when there is a long delay between creating the face and calling face.processEvents()?

I guess, my problem to connect NLSR with NFD in my BananaPro is related to that issue (ndn-cxx).

Dear folks

Given that Banana Pro has a slower CPU, could this be caused by #2742 "Face creation fails due to heavy application processing before calling processEvents"<http://redmine.named-data.net/issues/2742>?

Yours, Junxiao

I just successfully compile and install ndn-cxx, NFD and NLSR on Banana Pro (design and produced by LeMaker - http://www.lemaker.org/).

I can run NFD as usual and create face and register prefix using nfdc. After that i run several test using ndn-tlv-ping and ndn-traffic and everything is run smoothly.

The problem is, when i run NLSR, it will simply throw error message "ERROR: error while connecting to the forwarder" even though NFD is running. In nlsr log file it is just simply throw the same error message "ERROR: error while connecting to the forwarder". Something like below
