ChronoChat

ChronoChat is a multiparty chat application that demostrates our synchronization primitive that we call ChronoSync.

Note that after you click to close ChronoChat, it will keep running on your system tray. To restore it to normal size window, you have to click on the system tray icon (normally on the upper right corner of your screen). Clicking on the dock won't work for now and is still on the to-do list (because I'm using qt for gui, not the native Cocoa framework).

Known Issues

When you switch to a new room, you'll temporarily see yourself in two nodes for a minute or so. It won't affect others, just yourself. Hopefully it's not so disturbing.
Sometimes you may not get the most up-to-date chat history.

For those who wants (or is forced to) compile from source code

Compilation steps for OSX

Install MacPorts, if not yet installed (http://www.macports.org/) and configure NDN ports repository (https://github.com/named-data/ccnx/wiki/Using-ccnx-with-macports). If your Macports are installed in /opt/local, add the following line at the end of /opt/local/etc/macports/sources.conf before the default port repository:
```
 rsync://macports.named-data.net/macports/
```

Update port definitions and install (+load) required packages

 $ sudo port selfupdate

 # Install and CCNx
 sudo port install ccnx
 sudo port load ccnx

 # Install ChronoChat dependencies
 sudo port install pkgconfig protobuf-cpp boost qt4-mac

Fetch source code with submodules

 git clone --recursive git://github.com/named-data/ChronoChat

If you already cloned repository, you can update submodules this way:

    git submodule update --init

Configure and install ChronoSync

 cd ChronoChat/ChronoSync
 ./waf configure
 ./waf
 sudo ./waf install

Note, you may need to add --ndnx=<DIR> or --openssl=<DIR> flags to ./waf configure if NDNx and/or openssl cannot be found.

Configure and build ChronoChat

 cd ..
 PKG_CONFIG_PATH=/opt/local/lib/pkgconfig:/usr/local/lib/pkgconfig:/usr/lib/pkgconfig ./waf configure
 ./waf

Congratulations! build/ChronoChat.app is ready to use (on a Mac).

Compilation steps for Ubuntu 12.04

Install dependencies

 # General dependencies (build tools and dependencies for CCNx)
 sudo apt-get install git libpcap-dev libxml2-dev make libssl-dev libexpat-dev g++ pkg-config

 # ChronoSync/ChronoChat dependencies
 sudo apt-get install libprotobuf-dev protobuf-compiler libevent-dev
 sudo apt-get install libboost1.48-all-dev
 sudo apt-get install qt4-dev-tools

NOTE Only 1.48 version of boost libraries should be installed from packages. Since Ubuntu 12.04 ships with two versions, please make sure that 1.46 is not present, otherwise result is not guaranteed.

Download and install NDN fork of CCNx software

 git clone git://github.com/named-data/ccnx
 cd ccnx
 ./configure
 make
 sudo make install

Fetch source code with submodules

 git clone --recursive git://github.com/named-data/ChronoChat

If you already cloned repository, you can update submodules this way:

    git submodule update --init

Configure and install ChronoSync

 cd ChronoChat/ChronoSync
 ./waf configure
 ./waf
 sudo ./waf install
 sudo ldconfig

Note, you may need to add --ndnx=<DIR> or --openssl=<DIR> flags to ./waf configure if NDNx and/or openssl cannot be found.

Configure and build ChronoChat
```
 cd ..
 ./waf configure
 ./waf
```

Congratulations! build/ChronoChat is ready to use. Do not forget to start ccnd and configure FIB before using ChronoChat.
