 Getting started with ndn-cxx
 ============================

 Supported platforms
 -------------------

 ndn-cxx uses continuous integration and has been tested on the following
 platforms:

 -  Ubuntu 12.04 (64-bit and 32-bit)
 -  Ubuntu 13.10 (64-bit and 32-bit)
 -  OS X 10.8
 -  OS X 10.9

 ndn-cxx is known to work on the following platforms, although they are not officially
 supported:

 -  Ubuntu 14.04
 -  Fedora >= 20
 -  FreeBSD >= 10.0
 -  Raspberry Pi

 Prerequisites
 -------------

 Required:
 ~~~~~~~~~

 -  ``python`` >= 2.6
 -  ``libcrypto``
 -  ``libsqlite3``
 -  ``libcrypto++``
 -  ``pkg-config``
 -  Boost libraries >= 1.48
 -  OSX Security framework (on OSX platform only)

 Following are the detailed steps for each platform to install the compiler, all necessary
 development tools and libraries, and ndn-cxx prerequisites.

 -  OS X

    Install Xcode. In Xcode Preferences > Downloads, install "Command
    Line Tools".

    If using MacPorts, dependencies can be installed using the following
    commands::

        sudo port install pkgconfig boost sqlite3 libcryptopp

 -  Ubuntu 12.04, Ubuntu 13.10

    In a terminal, enter::

        sudo apt-get install build-essential
        sudo apt-get install libssl-dev libsqlite3-dev libcrypto++-dev

        # For Ubuntu 12.04
        sudo apt-get install libboost1.48-all-dev

        # For Ubuntu 13.10
        sudo apt-get install libboost-all-dev

 - Fedora >=20

    In a terminal, enter::

        sudo yum install gcc-g++ git
        sudo yum install openssl-devel sqlite-devel cryptopp-devel boost-devel

 Optional:
 ~~~~~~~~~

 To build tutorials, manpages, and API documentation the following
 dependencies need to be installed:

 -  ``doxygen``
 -  ``graphviz``
 -  ``python-sphinx`` and sphinx extensions ``sphinxcontrib-doxylink``,
    ``sphinxcontrib-googleanalytics``

 The following lists steps for common platforms to install these prerequisites:

 -  On OS X 10.8 and 10.9 with MacPorts::

        sudo port install doxygen graphviz py27-sphinx sphinx_select
        sudo port select sphinx py27-sphinx

        # Install sphinx extensions
        sudo port install py27-pip
        sudo port select pip pip27
        sudo pip install sphinxcontrib-doxylink sphinxcontrib-googleanalytics

 -  On Ubuntu >= 12.04::

        sudo apt-get install doxygen graphviz python-sphinx python-pip
        sudo pip install sphinxcontrib-doxylink sphinxcontrib-googleanalytics

 -  On Fedora >= 20::

        sudp yum install doxygen graphviz python-sphinx
        sudo pip install sphinxcontrib-doxylink sphinxcontrib-googleanalytics

 Build
 -----

 (These are instructions to build ndn-cxx. To do development of ndn-cxx
 code and update the build system, see Development.)

 To build in a terminal, change directory to the ndn-cxx root. Enter:

 ::

     ./waf configure
     ./waf
     sudo ./waf install

 This builds and installs the following items:

 -  ``<LIBPATH>/libndn-cxx.a``: static NDN C++ library
 -  ``<LIBPATH>/pkgconfig/libndn-cxx.pc``: pkgconfig file storing all
    neccessary flags to build against the library. For example, if
    pkgconfig or pkgconf package is installed and ``PKG_CONFIG_PATH`` is
    configured properly (or ``<LIBPATH>/pkgconfig`` is a default path),
    ``pkgconfig --libs --clflags libndn-cxx`` will return all necessary
    compile and link flags for the library.
 -  ``<BINPATH>/tlvdump``: a simple tool to dump contents of
    TLV-formatted data
 -  ``<BINPATH>/ndncatchunks3``: a simplified equivalent to ndncatchunks2
    in NDNx package
 -  ``<BINPATH>/ndnputchunks3``: a simplified equivalent to ndnputchunks2
    in NDNx package
 -  ``<BINPATH>/ndnsec``: tool to manage NDN keys and certificates
 -  ``<BINPATH>/ndnsec-*``: convenience scripts for ``ndnsec`` tools

 If configured with tests: ``./waf configure --with-tests``), the above
 commands will also produce:

 -  ``build/unit-tests``: A unit test binary for the library

 1.5GB available memory per CPU core is necessary for efficient compilation.
 On a multi-core machine with less than 1.5GB available memory per CPU core,
 limit the objects being compiled in parallel with ``./waf -jN`` where N is the amount
 of available memory divided by 1.5GB (eg. ``./waf -j1`` for 1.5GB memory),
 which could usually avoid memory thrashing and result in faster compilation.

 Build with examples
 -------------------

 By default, examples in ``examples/`` are not build.  To enable them, use
 ``--with-examples`` configure option:

 ::

     ./waf configure --with-examples
     ./waf

 To run examples:

 ::

     # trivial producer app
     ./build/examples/producer

     # trivial consumer app
     ./build/examples/consumer

     # trivial consumer app with timers
     ./build/examples/consumer-with-timer

 If you want to test out a sample application, just create a ``.cpp`` file in ``examples/``
 folder and it will be compiled on the next run on ``./waf``.  For example:

 ::

     cp examples/consumer.cpp examples/my-new-consumer-app.cpp
     ./waf
     ./build/examples/my-new-consumer-app


 Debug symbols
 ~~~~~~~~~~~~~

 The default compiler flags enable debug symbols to be included in binaries (i.e., ``-g``
 flag for ``./waf configure`` and ``-g3`` for ``./waf configure --debug``).  This
 potentially allows more meaningful debugging information if your application crashes.

 If it is undesirable, default flags can be easily overridden:

 ::

     CXXFLAGS="-O2" ./waf configure --prefix=/usr --sysconfdir=/etc
     ./waf
     sudo ./waf install

 Documentation
 -------------

 ndn-cxx tutorials and API documentation can be built using the following
 commands:

 ::

     # Full set of documentation (tutorials + API) in build/docs
     ./waf docs

     # Only tutorials in `build/docs`
     ./waf sphinx

     # Only API docs in `build/docs/doxygen`
     ./waf doxgyen

 Manpages are automatically created and installed during the normal build
 process (e.g., during ``./waf`` and ``./waf install``), if
 ``python-sphinx`` module is detected during ``./waf configure`` stage.
 By default, manpages are installed into ``${PREFIX}/share/man`` (where
 default value for ``PREFIX`` is ``/usr/local``). This location can be
 changed during ``./waf configure`` stage using ``--prefix``,
 ``--datarootdir``, or ``--mandir`` options.

 For more details, refer to ``./waf --help``.

 Development Build
 -----------------

 The following is the suggested configure commands for development build.

 ::

     ./waf configure --debug --with-tests
     ./waf
     sudo ./waf install

 In the development build all compiler optimizations are disabled by
 default and all warnings are treated as error. The default behavior can
 be overridden by setting ``CXXFLAGS`` environment variable before
 running ``./waf configure``:

 ::

     CXXFLAGS="-O1 -g3" ./waf configure --debug --with-tests
