    <title>Installation of libinput</title>

    <para>
      Install <application>libinput</application> by running the following
      commands:
    </para>

<screen><userinput>meson --prefix $XORG_PREFIX \
      -Dudev-dir=/lib/udev  \
      -Ddebug-gui=false     \
      -Dtests=false         \
      -Ddocumentation=false \
      -Dlibwacom=false      \
      build &amp;&amp;
cd build    &amp;&amp;
ninja</userinput></screen>

    <note>
      <para>If you want to run the tests, remove -Dtests from the
      <command>meson</command> command above. The external
      library, libunwind, must be installed.</para>

      <para> To run the tests for this package, valgrind requires a version of
      the /lib/ld-2.23.so (or later) library with debugging symbols present.
      Normally in LFS these debugging symbols are stripped at the end of
      Chapter 6. To get this library, glibc must be rebuilt with the current
      glibc version using the same compiler that was used to build LFS.  The
      ld-2.23.so can then be renamed to ld-2.23.so.dbg and copied to /lib.
      Then a symlink needs to be changed:</para>

      <screen role="nodump"><userinput>ln -sfv ld-2.23.so.dbg /lib/ld-linux-x86-64.so.2</userinput></screen>

      <para>Adjust the above instruction as needed for a 32-bit system
      or for a different version of glibc</para>

    </note>

    <para>
      Running the testsuite for this package can cause problems. 
      It creates a number of dummy input devices on the currently
      running system that can lead to crashing a local X server or
      a desktop environment. If you understand the risks and have
      the optional <xref linkend="check"/> and
      <xref linkend="valgrind"/> packages installed, the regression
      tests can be run as the <systemitem
      class="username">root</systemitem> user with
      <userinput>ninja check</userinput>. Note that depending on
      the system configuration and hardware, some tests may fail.
    </para>

    <para>
      Now, as the <systemitem class="username">root</systemitem> user:
    </para>

<screen role="root"><userinput>ninja install</userinput></screen>

    <para>
      If <xref linkend="doxygen"/> and <xref linkend="graphviz"/> were
      present during the build, you can install the generated documentation
      by running the following commands as the <systemitem
      class="username">root</systemitem> user:
    </para>

<screen role="root"><userinput>install -v -dm755 $XORG_PREFIX/share/doc/libinput-&libinput-version; &amp;&amp;
cp -rv doc/html/* $XORG_PREFIX/share/doc/libinput-&libinput-version;</userinput></screen>
