      <para><application>Libdbus</application> is part of the D-Bus sources.
      You should first unpack the D-Bus tarball and change to the
      <filename>dbus-&dbus-version;</filename> directory.</para>

    <para>Prepare Libdbus for compilation:</para>

<screen><userinput remap="configure">./configure --prefix=/usr     \
            --sysconfdir=/etc \
            --localstatedir=/var</userinput></screen>

    <para>Compile the package:</para>

<screen><userinput remap="make">make -C dbus libdbus-1.la</userinput></screen>

    <para>This package does come with a testsuite, but it is not
    possible to run it because only part of the package was
    built.</para>

    <para>Install the package:</para>

<screen><userinput remap="install">make -C dbus lib_LTLIBRARIES=libdbus-1.la \
     install-libLTLIBRARIES \
     install-dbusincludeHEADERS \
     install-nodist_dbusarchincludeHEADERS
make install-pkgconfigDATA</userinput></screen>

    <para>The shared library needs to be moved to
    <filename class="directory">/lib</filename>, and as a result the
    <filename class="extension">.so</filename> file in
    <filename class="directory">/usr/lib</filename> will need to be recreated:</para>

<screen><userinput remap="install">mv -v /usr/lib/libdbus-1.so.* /lib
ln -sfv ../../lib/$(readlink /usr/lib/libdbus-1.so) /usr/lib/libdbus-1.so</userinput></screen>
