    <title>Installation of MesaLib</title>

    <para>If you've installed the X Window System into any prefix other than
    <filename class="directory">/usr</filename>, then you'll need to adjust the
    commands below for your system.  Correct several hard coded directories 
    in the source files with the following commands:</para>

<screen><userinput>find . -type f -exec sed -i 's@/usr/X11R6@/usr@g' {} \; &amp;&amp;
sed -i 's@lib/modules@lib/X11/modules@' src/glx/x11/dri_glx.c</userinput></screen>

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

<screen><userinput>make linux-dri</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>bin/installmesa /usr &amp;&amp;
mkdir -v -p /usr/lib/X11/modules/dri &amp;&amp;
install -v -m755 lib/*dri* /usr/lib/X11/modules/dri</userinput></screen>

    <para>If you've extracted the GLUT and Demos packages as well, then 
    build the test programs with the following commands:</para>

<screen><userinput>cd progs/xdemos &amp;&amp;
make PROGS='glxinfo glxgears'</userinput></screen>

    <para>Install the demos as the
    <systemitem class="username">root</systemitem> user:</para>

<screen role="root"><userinput>install -v -m755 glxinfo glxgears /usr/bin</userinput></screen>

    <note>
      <para>If building <xref linkend="xorg7"/>, do not 
      remove the Mesa source tree yet, it will be required to build the 
      X server.</para>
    </note>

    <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><userinput role="root">ln -s -v <replaceable>[/usr/X11]</replaceable>/include/GL /usr/include</userinput></screen>

    <title>Command Explanations</title>

    <para><command>find...sed -i 's@/usr/X11R6@/usr@'...</command>: This 
    command corrects several hard coded references to the X11R6 default
    installation path.</para>

    <para><command>sed -i 's@lib/modules@lib/X11/modules@' 
    src/glx/x11/dri_glx.c</command>: This command corrects a hard coded
    reference to the module directory.</para>

    <para><command>bin/installmesa</command>: Mesa uses a custom installation
    script as opposed to the normal <parameter>install</parameter> make 
    target.</para>

    <para><command>install -v -m755 lib/*dri* 
    /usr/lib/X11/modules/dri</command>: installs the DRI modules.</para>

    <para><command>make PROGS='glxinfo glxgears'</command>: build only
    the glxinfo and glxgears programs.</para>

    <para><command>install -v -m755 glxinfo glxgears /usr/bin</command>: 
    Installs only the glxinfo and glxgears programs.</para>
