    <title>Installation of MesaLib</title>

    <note><para>Unlike other packages, the
    <filename>MesaLib-&mesalib-version;.tar.bz2</filename>
    archive will extract to the
    <filename class="directory">Mesa-&mesalib-version;</filename>
    directory.</para></note>

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

<screen><userinput>sed 's@FLAGS=\"-g@FLAGS=\"@' -i configure &amp;&amp;
patch -Np1 -i ../MesaLib-&mesalib-version;-llvm_3.0-1.patch   &amp;&amp;
patch -Np1 -i ../MesaLib-&mesalib-version;-add_xdemos-2.patch &amp;&amp;
./configure $XORG_CONFIG --enable-xcb &amp;&amp;
make</userinput></screen>

    <para>This package does not come with a test suite.</para>

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

<screen role="root"><userinput>make install &amp;&amp;
install -v -m755 -d ${XORG_PREFIX}/share/doc/MesaLib-&mesalib-version; &amp;&amp;
install -v -m644    docs/* \
                    ${XORG_PREFIX}/share/doc/MesaLib-&mesalib-version;</userinput></screen>

    <para>Finally, if installing to any prefix other than
    <filename class="directory">/usr</filename>, you should create symlinks
    to the GL headers in <filename class="directory">/usr/include</filename>.
    Execute the following command as the
    <systemitem class="username">root</systemitem> user:</para>

<screen role="root"><userinput>ln -s -v ${XORG_PREFIX}/include/GL  /usr/include &amp;&amp;
ln -s -v ${XORG_PREFIX}/include/EGL /usr/include &amp;&amp;
ln -s -v ${XORG_PREFIX}/include/KHR /usr/include</userinput></screen>

  <sect2 role="commands">
    <title>Command Explanations</title>

    <para><command>sed 's@FLAGS=\"-g@FLAGS=\"@' -i configure</command>: by
    default, Mesa builds with debugging symbols.  Remove the -g switch from
    both <envar>CFLAGS</envar> and <envar>CXXFLAGS</envar> with this
    command.</para>

    <para><option>--enable-xcb</option>: use the XCB backend instead of the
    default XLib backend for GLX.</para>

    <para><option>--enable-motif</option>: build motif widgets into the
    GL widgets library (requires <application>lesstif</application>).</para>

    <para><option>--with-gallium-driver=...</option>: build additional gallium
    drivers. Defaults to r300, r600, and swrast. You must specify i9xx and
    nouveau drivers.</para>
