5To use the fmt library, add :file:`format.h` and :file:`format.cc` from
6a `release archive <https://github.com/fmtlib/fmt/releases/latest>`_
7or the `Git repository <https://github.com/fmtlib/fmt>`_ to your project.
8Alternatively, you can :ref:`build the library with CMake <building>`.
9
10If you are using Visual C++ with precompiled headers, you might need to add
11the line ::
12
13   #include "stdafx.h"
14
15before other includes in :file:`format.cc`.

19Building the library
20====================
21
22The included `CMake build script`__ can be used to build the fmt
23library on a wide range of platforms. CMake is freely available for
24download from http://www.cmake.org/download/.
25
26__ https://github.com/fmtlib/fmt/blob/master/CMakeLists.txt
27
28CMake works by generating native makefiles or project files that can
29be used in the compiler environment of your choice. The typical
30workflow starts with::
31
32  mkdir build          # Create a directory to hold the build output.
33  cd build
34  cmake <path/to/fmt>  # Generate native build scripts.
35
36where :file:`{<path/to/fmt>}` is a path to the ``fmt`` repository.
37
38If you are on a \*nix system, you should now see a Makefile in the
39current directory. Now you can build the library by running :command:`make`.
40
41Once the library has been built you can invoke :command:`make test` to run
42the tests.
43
44If you use Windows and have Visual Studio installed, a :file:`FORMAT.sln`
45file and several :file:`.vcproj` files will be created. You can then build them
46using Visual Studio or msbuild.
47
48On Mac OS X with Xcode installed, an :file:`.xcodeproj` file will be generated.
49
50To build a `shared library`__ set the ``BUILD_SHARED_LIBS`` CMake variable to
51``TRUE``::
52
53  cmake -DBUILD_SHARED_LIBS=TRUE ...

56
57Building the documentation
58==========================
59
60To build the documentation you need the following software installed on your
61system:
62
63* `Python <https://www.python.org/>`_ with pip and virtualenv
64* `Doxygen <http://www.stack.nl/~dimitri/doxygen/>`_
65* `Less <http://lesscss.org/>`_ with ``less-plugin-clean-css``.
66  Ubuntu doesn't package the ``clean-css`` plugin so you should use ``npm``
67  instead of ``apt`` to install both ``less`` and the plugin::
68
69    sudo npm install -g less less-plugin-clean-css.
70
71First generate makefiles or project files using CMake as described in
72the previous section. Then compile the ``doc`` target/project, for example::
73
74  make doc
75
76This will generate the HTML documentation in ``doc/html``.
77
78Android NDK
79===========
80
81fmt provides `Android.mk file`__ that can be used to build the library
82with `Android NDK <https://developer.android.com/tools/sdk/ndk/index.html>`_.
83For an example of using fmt with Android NDK, see the
84`android-ndk-example <https://github.com/fmtlib/android-ndk-example>`_
85repository.
86
87__ https://github.com/fmtlib/fmt/blob/master/Android.mk
88
89Homebrew
90========
91
92fmt can be installed on OS X using `Homebrew <http://brew.sh/>`_::
93
94  brew install fmt
