    <warning>
      <para>
        You may notice that there are several newer version of
        <application>libdrm</application> available upstream.
        However, we do not recommend using any later version than
        this one if you are going to build
        <xref linkend="mesalib"/> using BLFS instructions.
      </para>
    </warning>

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

<screen><userinput>./configure --prefix=$XORG_PREFIX            \
            --enable-udev                    \

            --enable-nouveau-experimental-api &amp;&amp;
make</userinput></screen>

    <para>
      To check the results, issue <command>make check</command>. Note that
      some tests may fail depending on the video hardware installed in the
      machine.

    <para>
      <option>--enable-nouveau-experimental-api</option>: This parameter
      enables building of Nouveau (Open Source NVidia drivers) DRM interface
      library as well as corresponding headers.

    <para>
      <option>--enable-vmwgfx-experimental-api</option>: This parameter
      enables use of vmwgfx experimental kernel API used by the
      VMware 3D Gallium driver.
