/**
@page building_libinput libinput build instructions
Instructions on how to build libinput and its tools and how to build against
libinput.
@section building Building libinput
libinput uses automake, a build is usually the following three-step process
@code
$> git clone git://anongit.freedesktop.org/git/wayland/libinput
$> cd libinput
$> ./autogen.sh --prefix=/usr --libdir=/usr/lib64
$> make
$> sudo make install
@endcode
@note On Debian-based distributions including Ubuntu and its derivatives skip the
```--libdir=/usr/lib64``` argument.
A successful build requires the @ref building_dependencies to be installed
at configure time.
@subsection building_dependencies Build dependencies
libinput has a few build-time dependencies that must be installed prior to
running configure. In most cases, it is sufficient to install the
dependencies that your distribution uses to build the libinput package.
These can be installed with one of the following commands:
<ul>
<li><b>Debian/Ubuntu</b> based distributions: ```sudo apt-get build-dep
libinput```</li>
<li><b>Fedora 22</b> and later: ```sudo dnf builddep libinput```</li>
<li><b>SuSE/RHEL/CentOS/Fedora 21</b> and earlier: ```sudo yum-builddep libinput```</li>
<li><b>Arch</b>:
<pre>
$> abs extra/libinput
$> cd $(mktemp -d)
$> cp /var/abs/extra/libinput/PKGBUILD .
$> makepkg --syncdeps --nobuild
</pre>
</li>
</ul>
If dependencies are missing, a message ```No package 'foo' found``` will be
shown during the configure stage. See
<a href="https://who-t.blogspot.com.au/2014/05/configure-fails-with-no-package-foo.html">this blog post here</a>.
for instructions on how to fix it.
@subsection building_libwacom Building without libwacom
libwacom is required by libinput's tablet code to gather additional
information about tablets that is not available from the kernel device
itself. libwacom is required by default but can be skipped when @ref
building with the ``--disable-libwacom`` argument.
@code
$> ./autogen.sh --disable-libwacom --prefix=/usr --libdir=/usr/lib64
@endcode
Disabling libwacom is safe to do for environments where full tablet support
is not required. Note that libinput provides tablet support even without
libwacom, but some features may be missing or working differently.
@subsection buildling_event-gui Building the graphical helper tool
Only the commandline @ref tools are installed by distributions. The
@ref event-gui graphical helper tools is only available in the source
repository.
The graphical helper tool is optional by default and requires extra
libraries to build. If these libraries are not detected, the tool will not
be built. If you need the tool for debugging purposes, use the
``--enable-event-gui`` argument when @ref building.
@code
$> ./autogen.sh --enable-event-gui --prefix=/usr --libdir=/usr/lib64
@endcode
As usual, any missing library headers will then trigger an error and can be
addressed one-by-one.
@section building_against Building against libinput
libinput provides a
[pkg-config](https://www.freedesktop.org/wiki/Software/pkg-config/) file.
Software that uses libinput should use pkg-config and the
`PKG_CHECK_MODULES` autoconf macro.
Otherwise, the most rudimentary way to compile and link a program against
libinput is:
gcc -o myprogram myprogram.c `pkg-config --cflags --libs libinput`
For further information on using pkgconfig see the pkg-config documentation.
