NFD

Please upload your code to a public GitHub repository so I can help.

The issue is reproducible with the ndncpp examples which is why I suspect it may be with the library. The previous ndnping with ndnx does not have this issue. Please see my previous update for exact scenario replication steps.

I believe the prefix doesn't show up after producer restart is a bug in ndnd-tlv.
It is reported as ndnd-tlv issue 1.

This actually a small bug in ndn-cpp. The registration request is not unique (in the current hack) and require MustBeFresh selector, which is not by default assumed in NDN-TLV.

Also, the application requires libboost1.47(boost/asio/signal_set.hpp) or higher to handle signals from the user that will abruptly stop the application execution. Have updated this requirement in the README and the code should build and execute successfully now.

Jeral, i hope you saw the uploaded patch to ping to gerrit (http://gerrit.named-data.net/#/c/195/). Can you review it and if it's ok, incorporate with your code?

Yes I tested it on Ubuntu and it works fine, the application gets compiled and installed without issues. However, it failed on OSX and mentioned that it could not find pkg-config even when it was installed. I am assuming OSX installations are made available per user and was therefore inaccessible for my user account. Will check that and update.

OS X pkg-config shouldn't be per-user. On Arizona's Mac Mini:

monaco:~ jeraldabraham$ which pkg-config
/opt/local/bin/pkg-config
monaco:~ jeraldabraham$ pkg-config --cflags --libs libndn-cpp-dev
-I/opt/local/include -L/opt/local/lib -lsqlite3 -lndn-cpp-dev -lssl -lcrypto -lcryptopp -framework Security -lboost_system-mt -lboost_filesystem-mt 

Here libndn-cpp-dev is installed from Macports.

Are you using macports? You may need to configure PKG_CONFIG_PATH (add a note in README.md or INSTALL.md)

Depending on where you have installed ndn-cpp-dev (assuming in /usr/local):

PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./waf configure 

If ndn-cpp-dev is installed from macports, then

PKG_CONFIG_PATH=/opt/local/lib/pkgconfig ./waf configure 

Here is an extract pf the config log waf produces when it fails to find pkg-config

    ----------------------------------------
    Checking for program pkg-config
    not found
    find program=['pkg-config'] paths=['/usr/bin', '/bin', '/usr/sbin', '/sbin', '/usr/local/bin'] var='PKGCONFIG' -> ''
    from /Users/jeraldabraham/ndn/src/ndntlvping: Could not find the program pkg-config

The OSX box has pkg-config installed inside the opt folder, this is another reason why compilation also fails to find the boost libraries even when boost is installed on the machine (but it is incide the /opt path and not in the usual /usr path).

Oh. That is simple :)

sudo port install pkgconfig

Updated:
Misread your reply. Still simple, but different approach. You need to update your PATH variable (which for some reason does not include /opt/local/bin). Or you can specify pkgconfig program directly

PKGCONFIG=/opt/local/bin/pkg-config ./waf configure

To update PATH, I have the following in my ~/.bashrc file:

export PATH=\
/opt/local/bin:/opt/local/sbin:\
/usr/local/bin:\
$PATH

No Alex. pkgconfig was already installed.
The issue stopped after I configured the PKGCONFIG variable.

    export PKGCONFIG=/opt/local/lib/pkgconfig

Now the issue is with the ndn-cpp-dev library

    ----------------------------------------
    Checking for 'libndn-cpp-dev'
    ['/opt/local/lib/pkgconfig', '--cflags', '--libs', 'libndn-cpp-dev']
    not found
    from /Users/jeraldabraham/ndn/src/ndntlvping: The configuration failed

I am sure the latest ndn-cpp-dev code in git includes a waf script which configures pkgconfig for library flags retrieval.
However, I think the OSX machine needs to be installed with this latest ndn-cpp-dev library as the new one was updated on git just a few days ago.

What about this:

PKGCONFIG=/opt/local/bin/pkg-config PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./waf configure

or

export PKGCONFIG=/opt/local/bin/pkg-config
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
./waf configure

This definitely will not work.

Macports installs to a weird location:

monaco:ndn-tlv-ping shijunxiao$ ls /opt/local/lib/pkgconfig/libndn-cpp-dev.pc 
/opt/local/lib/pkgconfig/libndn-cpp-dev.pc

Yes the follow ensures the configure succeeds.

    export PKGCONFIG=/opt/local/bin/pkg-config
    export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
    ./waf configure

But I still think the ndn-cpp-dev library needs to be updated.

    ../ndn-tlv-pingserver.cpp:27:13: error: no matching conversion for functional-style cast from 'ptr_lib::shared_ptr<boost::asio::io_service>' to 'ndn::Face'
    face_ = Face(ioService_);

I remember that this constructor was recently added. How can I check if the ndn-cpp-dev library installed on a machine is up to date?

This is what I have from Macports. I already executed sudo port selfupdate.

monaco:ndn-tlv-ping shijunxiao$ sudo port info ndn-cpp-dev
ndn-cpp-dev @0.2.2_1 (net)
Variants:             universal

Description:          C++ development library for NDN.
Homepage:             https://github.com/cawka/ndn-cpp

Build Dependencies:   autoconf, automake, libtool
Library Dependencies: boost, openssl, libcryptopp, sqlite3
Platforms:            darwin
License:              BSD

This looks like an old version.

One solution is adding a --with-ndn-cpp-dev option to wscript, so that you can specify a user copy of libndn-cpp-dev

I have removed that option, since compiling against the library requires a number of dependencies that are known to the library during compilation, but cannot be easily guessed when linking to the library.

In any case, I just updated macports definitions, so you should sudo port selfupdate and then reinstall ndn-cpp-dev, ndnd-tlv, and ndn-cpp-security-tools (I recommend reinstalling, not updating, but either should work).

I have added the waf script with the ndn-tlv-ping repository.
The waf building works fine one Ubuntu and OSX.
