[Nfd-dev] [Operators] "No buffer space available"

[Dehart, John]

All:

Here is my proposed plan for installing a debug symbol equipped NFD on the Testbed nodes.
I decided to install it in a completely separate directory so normal builds would be less likely
to get confused.

Please let me know if you see anything wrong.

John


# Install ndn-cxx version 0.5.1-60-gb555b00
git clone http://github.com/named-data/ndn-cxx
cd ndn-cxx
git checkout b555b00c280b9c9ed46f24a1fbebc73b720601af
./waf --debug --prefix=/usr/local/ndn-dbg configure
./waf
sudo ./waf install

export PKG_CONFIG_PATH="/usr/local/ndn-dbg/lib/pkgconfig"

# install NFD; Ashlesh's version 0.5.1-73-gbc7cb95
git clone https://github.com/agawande/NFD
cd ../NFD
git checkout bc7cb95
git submodule init && git submodule update
./waf --debug --prefix=/usr/local/ndn-dbg configure
./waf
sudo ./waf install

# Ubuntu 14.04: Update /etc/init/nfd.conf to run /usr/local/ndn-dbg/bin/nfd in place of /usr/bin/nfd
# Ubuntu 16.04: Update /etc/systemd/system/multi-user.target.wants/nfd.service to run /usr/local/ndn-dbg/bin/nfd in place of /usr/bin/nfd
