[Mini-NDN] [mini-ndn] Failed to read configuration file

[Teng Liang]

Hi folks,

I failed to run the latest version of mini-ndn (on Linux) with the
following errors.

First, mini-ndn tried to copy the nfd configuration file from
'/usr/local/etc/ndn/', but failed.

> cp: cannot stat `/usr/local/etc/ndn/nfd.conf.sample': No such file or
directory

My configuration files were in '/etc/ndn/'; I tried to copy them to
'/usr/local/etc/ndn/' and ran minindn again. Here are the error messages
from a.log:

1446853834.224102 FATAL: [NFD] Failed to read configuration file:

Another question is how are topologies files generated, manually or by some
scripts from minindn? What's the format?

Thanks,

Teng
