Using libbson In Your C Program
===============================

Include bson.h
--------------

All libbson's functions and types are available in one header file. Simply include ``bson.h``:

.. literalinclude:: ../examples/hello_bson.c
  :caption: hello_bson.c
  :start-after: -- sphinx-include-start --

CMake
-----

The libbson installation includes a `CMake config-file package`_, so you can use CMake's `find_package`_ command to import libbson's CMake target and link to libbson (as a shared library):

.. literalinclude:: ../examples/cmake/find_package/CMakeLists.txt
  :caption: CMakeLists.txt
  :start-after: -- sphinx-include-start --

You can also use libbson as a static library instead: Use the ``mongo::bson_static`` CMake target:

.. literalinclude:: ../examples/cmake/find_package_static/CMakeLists.txt
  :start-after: -- sphinx-include-start --
  :emphasize-lines: 1, 5

.. _find_package: https://cmake.org/cmake/help/latest/command/find_package.html

pkg-config
----------

If you're not using CMake, use `pkg-config`_ on the command line to set header and library paths:

.. literalinclude:: ../examples/compile-with-pkg-config.sh
  :start-after: -- sphinx-include-start --

Or to statically link to libbson:

.. literalinclude:: ../examples/compile-with-pkg-config-static.sh
  :start-after: -- sphinx-include-start --
