Davide Pesavento534b8412018-12-08 19:19:09 -0500129.. note::
Davide Pesaventoab7300b2020-04-09 00:51:41 -0400130 These are instructions for regular builds of ndn-cxx (release mode). If you are
131 planning to develop the ndn-cxx code itself, you should do a :ref:`Development build`.
Alexander Afanasyevc5452c52014-04-29 17:21:51 -0700132
Davide Pesavento933a5672020-07-03 22:32:43 -0400133To build in a terminal, change directory to the ndn-cxx root, then enter:
134
135.. code-block:: sh
Alexander Afanasyevc5452c52014-04-29 17:21:51 -0700136
Davide Pesaventofbca6112022-07-03 16:31:04 -0400137 ./waf configure
Alexander Afanasyevc5452c52014-04-29 17:21:51 -0700138 ./waf
139 sudo ./waf install
140
Davide Pesaventoab7300b2020-04-09 00:51:41 -0400141By default, only the shared variant of the ndn-cxx library will be built. To build the
Davide Pesavento933a5672020-07-03 22:32:43 -0400142static library, pass ``--enable-static`` to the ``./waf configure`` command:
143
144.. code-block:: sh
Alexander Afanasyev7ed29432015-06-05 18:01:16 -0700145
Spyridon Mastorakis5ebfda62015-07-21 20:57:40 -0700146 ./waf configure --enable-static
Alexander Afanasyev7ed29432015-06-05 18:01:16 -0700147
Davide Pesaventoab7300b2020-04-09 00:51:41 -0400148To disable the build of the shared library and build only the static library, use the
149additional ``--disable-shared`` option. Note that at least one variant of the library
150needs to be enabled.
Alexander Afanasyev7ed29432015-06-05 18:01:16 -0700151
Davide Pesavento933a5672020-07-03 22:32:43 -0400152.. code-block:: sh

Davide Pesaventoab7300b2020-04-09 00:51:41 -0400156On Linux, it is necessary to run the following command after the shared library has
Davide Pesavento933a5672020-07-03 22:32:43 -0400157been installed:
158
159.. code-block:: sh
Alexander Afanasyev7ed29432015-06-05 18:01:16 -0700160
Davide Pesavento534b8412018-12-08 19:19:09 -0500161 sudo ldconfig
Alexander Afanasyev7ed29432015-06-05 18:01:16 -0700162
Davide Pesavento534b8412018-12-08 19:19:09 -0500163.. note::
Davide Pesavento4dc4b3c2024-02-05 20:05:54 -0500164 On Linux, when the library is installed in a non-default location (generally, not in
165 ``/usr/lib`` or ``/usr/local/lib``), the following additional actions may be necessary.
Alexander Afanasyev7ed29432015-06-05 18:01:16 -0700166
Davide Pesavento4dc4b3c2024-02-05 20:05:54 -0500167 The library installation path should be added to ``/etc/ld.so.conf`` or to
168 ``/etc/ld.so.conf.d/*.conf`` before running ``ldconfig``. For example:
Davide Pesavento933a5672020-07-03 22:32:43 -0400169
170 .. code-block:: sh
Alexander Afanasyev7ed29432015-06-05 18:01:16 -0700171
Davide Pesavento4dc4b3c2024-02-05 20:05:54 -0500172 echo /usr/local/lib64 | sudo tee /etc/ld.so.conf.d/ndn-cxx.conf
173 sudo ldconfig
Alexander Afanasyev7ed29432015-06-05 18:01:16 -0700174
Davide Pesavento534b8412018-12-08 19:19:09 -0500175 Alternatively, the ``LD_LIBRARY_PATH`` environment variable can be set to point to
Davide Pesavento933a5672020-07-03 22:32:43 -0400176 the installation directory of the shared library:
177
178 .. code-block:: sh
Alexander Afanasyev7ed29432015-06-05 18:01:16 -0700179
Davide Pesavento4dc4b3c2024-02-05 20:05:54 -0500180 export LD_LIBRARY_PATH=/usr/local/lib64
Alexander Afanasyev7ed29432015-06-05 18:01:16 -0700181
Davide Pesavento534b8412018-12-08 19:19:09 -0500182The ``./waf install`` command installs the following files:
Alexander Afanasyev7ed29432015-06-05 18:01:16 -0700183
Davide Pesavento4dc4b3c2024-02-05 20:05:54 -0500184- ``<LIBDIR>/libndn-cxx.a``: static NDN C++ library (if enabled).
185- ``<LIBDIR>/libndn-cxx.so``, ``<LIBDIR>/libndn-cxx.so.<VERSION>`` (on Linux),
186 ``<LIBDIR>/libndn-cxx.dylib``, ``<LIBDIR>/libndn-cxx.<VERSION>.dylib`` (on macOS):
Davide Pesavento534b8412018-12-08 19:19:09 -0500187 shared NDN C++ library (if enabled).
Davide Pesavento4dc4b3c2024-02-05 20:05:54 -0500188- ``<LIBDIR>/pkgconfig/libndn-cxx.pc``: pkgconfig file storing all necessary flags to
Davide Pesaventoab7300b2020-04-09 00:51:41 -0400189 build against the library. For example, if the ``pkg-config`` or ``pkgconf-pkg-config``
190 package is installed and ``PKG_CONFIG_PATH`` is configured properly (or if
Davide Pesavento4dc4b3c2024-02-05 20:05:54 -0500191 ``<LIBDIR>/pkgconfig`` is a default search path), the command ``pkg-config --cflags
Davide Pesaventoab7300b2020-04-09 00:51:41 -0400192 --libs libndn-cxx`` will return all necessary compile and link flags for the library.
Davide Pesavento4dc4b3c2024-02-05 20:05:54 -0500193- ``<BINDIR>/ndnsec``: command-line tool to manage NDN keys and certificates.
194- ``<BINDIR>/ndnsec-*``: convenience aliases for ``ndnsec`` tools.
Alexander Afanasyevc5452c52014-04-29 17:21:51 -0700195
Davide Pesaventoab7300b2020-04-09 00:51:41 -0400196If configured with tests (``./waf configure --with-tests``), the above commands
197will also produce:
Alexander Afanasyevc5452c52014-04-29 17:21:51 -0700198
Davide Pesavento534b8412018-12-08 19:19:09 -0500199- ``build/unit-tests``: a unit test binary for the library.
Alexander Afanasyevc5452c52014-04-29 17:21:51 -0700200
Davide Pesaventoab7300b2020-04-09 00:51:41 -04002011.5 GB available memory per CPU core is necessary for efficient compilation. On a
202multi-core machine with less than 1.5 GB available memory per CPU core, limit the
203objects being compiled in parallel with ``./waf -jN``, where N is the amount of
204available memory divided by 1.5 GB (e.g., ``./waf -j2`` for 3 GB of memory). This
205should avoid memory thrashing and result in faster compilation.

Alexander Afanasyevc8bcd452014-05-12 17:58:47 -0700207Build with examples
208-------------------
209
Davide Pesaventoab7300b2020-04-09 00:51:41 -0400210By default, the examples in the ``examples/`` directory will not be built. To enable
Davide Pesavento933a5672020-07-03 22:32:43 -0400211them, pass ``--with-examples`` during the configuration step:
212
213.. code-block:: sh
Alexander Afanasyevc8bcd452014-05-12 17:58:47 -0700214
Davide Pesaventofbca6112022-07-03 16:31:04 -0400215 ./waf configure --with-examples

Alexander Afanasyev7ed29432015-06-05 18:01:16 -0700219
Davide Pesavento933a5672020-07-03 22:32:43 -0400220To run the examples:
221
222.. code-block:: sh
Alexander Afanasyevc8bcd452014-05-12 17:58:47 -0700223
224 # trivial producer app

232
Davide Pesaventoab7300b2020-04-09 00:51:41 -0400233If you want to make a new sample application, just create a ``.cpp`` file inside the
Davide Pesavento933a5672020-07-03 22:32:43 -0400234``examples/`` directory and it will be compiled during the next run of ``./waf``:

Alexander Afanasyev9b0e1142014-05-08 00:17:34 -0700245Debug symbols
Davide Pesaventoab7300b2020-04-09 00:51:41 -0400246-------------
Alexander Afanasyev9b0e1142014-05-08 00:17:34 -0700247
Davide Pesaventoab7300b2020-04-09 00:51:41 -0400248The default compiler flags include debug symbols in binaries. This should provide
249more meaningful debugging information if ndn-cxx or your application crashes.
Alexander Afanasyev9b0e1142014-05-08 00:17:34 -0700250
Eric Newberrybdfb53a2020-10-01 10:43:46 -0700251If this is not desired, the default flags can be overridden to disable debug symbols.
Davide Pesaventoab7300b2020-04-09 00:51:41 -0400252The following example shows how to completely disable debug symbols and configure
253ndn-cxx to be installed into ``/usr`` with configuration in the ``/etc`` directory.

Davide Pesavento933a5672020-07-03 22:32:43 -0400255.. code-block:: sh

Davide Pesaventoab7300b2020-04-09 00:51:41 -0400261Customizing the compiler
262------------------------
Alexander Afanasyev7ed29432015-06-05 18:01:16 -0700263
Davide Pesaventoab7300b2020-04-09 00:51:41 -0400264To build ndn-cxx with a different compiler (rather than the platform default), set the
265``CXX`` environment variable to point to the compiler binary. For example, to build
Davide Pesavento933a5672020-07-03 22:32:43 -0400266with clang on Linux, use the following:
267
268.. code-block:: sh
Alexander Afanasyevc5452c52014-04-29 17:21:51 -0700269
Davide Pesaventoab7300b2020-04-09 00:51:41 -0400270 CXX=clang++ ./waf configure

272Building the documentation
273--------------------------
274
Eric Newberrybdfb53a2020-10-01 10:43:46 -0700275Tutorials and API documentation can be built using the following commands:
Davide Pesavento933a5672020-07-03 22:32:43 -0400276
277.. code-block:: sh
Alexander Afanasyevc5452c52014-04-29 17:21:51 -0700278
279 # Full set of documentation (tutorials + API) in build/docs
280 ./waf docs
281
Davide Pesavento2349e282020-03-24 14:28:03 -0400282 # Only tutorials in build/docs
Alexander Afanasyevc5452c52014-04-29 17:21:51 -0700283 ./waf sphinx
284
Davide Pesavento2349e282020-03-24 14:28:03 -0400285 # Only API docs in build/docs/doxygen
Sepehr Abdous4fc6db22018-08-22 15:26:06 -0700286 ./waf doxygen
Alexander Afanasyevc5452c52014-04-29 17:21:51 -0700287
Davide Pesavento01cea502021-07-31 19:25:42 -0400288If ``sphinx-build`` is detected during ``./waf configure``, man pages will automatically
Davide Pesaventoab7300b2020-04-09 00:51:41 -0400289be built and installed during the normal build process (i.e., during ``./waf`` and
Davide Pesavento01cea502021-07-31 19:25:42 -0400290``./waf install``). By default, man pages will be installed into ``${PREFIX}/share/man``
Davide Pesaventoab7300b2020-04-09 00:51:41 -0400291(the default value for ``PREFIX`` is ``/usr/local``). This location can be changed
292during the ``./waf configure`` stage using the ``--prefix``, ``--datarootdir``, or
293``--mandir`` options.

Davide Pesaventoab7300b2020-04-09 00:51:41 -0400297.. _Development build:
Davide Pesavento534b8412018-12-08 19:19:09 -0500298
299Development build
Alexander Afanasyevc5452c52014-04-29 17:21:51 -0700300-----------------
301
Davide Pesavento933a5672020-07-03 22:32:43 -0400302The following is the suggested build procedure for development builds:
303
304.. code-block:: sh
Alexander Afanasyevc5452c52014-04-29 17:21:51 -0700305
Davide Pesaventofbca6112022-07-03 16:31:04 -0400306 ./waf configure --debug --with-tests
Alexander Afanasyevc5452c52014-04-29 17:21:51 -0700307 ./waf
308 sudo ./waf install
Davide Pesavento2349e282020-03-24 14:28:03 -0400309 sudo ldconfig # on Linux only
Alexander Afanasyevc5452c52014-04-29 17:21:51 -0700310
Davide Pesaventoab7300b2020-04-09 00:51:41 -0400311In a development build, most compiler optimizations will be disabled and all warnings
312will be treated as errors. This default behavior can be overridden by setting the
Davide Pesavento933a5672020-07-03 22:32:43 -0400313``CXXFLAGS`` environment variable before running ``./waf configure``, for example:
314
315.. code-block:: sh
Alexander Afanasyevc5452c52014-04-29 17:21:51 -0700316
Davide Pesavento81de5d92022-12-30 01:08:05 -0500317 CXXFLAGS="-O1 -g3 -Wall" ./waf configure --debug --with-tests
