+<H2>1. Unix/X11 Compilation and Installation</H1>
+
+<h3>1.1 Compilation</h3>
+
+<p>
+Mesa may be compiled in several different ways:
+</p>
+<ul>
+<li><b><em>Stand-alone/Xlib mode</em></b> - Mesa is compiled as
+a software renderer using Xlib to do all rendering.
+libGL.so is a self-contained rendering library.
+<p>
+To compile stand-alone Mesa type <b>make</b> in the top-level directory.
+You'll see a list of supported system configurations.
+Choose one from the list (such as linux-x86), and type:
+</p>
+<pre>
+ make linux-x86
+</pre>
+<p>This will produce libGL.so and several other libraries</p>
+</li>
+
+<li><b><em>DRI/accelerated</em></b> - The DRI hardware drivers (for ATI,
+Intel, Matrox, etc) are built.
+libGL.so implements the GLX extension and dynamically loads the DRI drivers.
+<p>
+To build the DRI drivers you'll first need to have the DRM (Direct
+Rendering Manager) kernel drivers and header files.
+They're available from the <a href="http://dri.sf.net/" target="_parent">DRI</a> project.
+</p>
+<p>
+You can get them from CVS by doing:
+<pre>
+cvs -d:pserver:anonymous@pds.freedesktop.org:/cvs/dri login
+(hit enter when prompted for a password)
+cvs -z3 -d:pserver:anonymous@pdx.freedesktop.org:/cvs/dri co drm
+</pre>
+<p>
+Make note of the directory in which the drm files are placed.
+</p>
+<p>
+See the <a href="http://dri.freedesktop.org/wiki/Building" target="_parent">
+DRI Building Instructions</a> for the steps to build the DRM modules.
+</p>
+<p>
+Next, in the <code>Mesa-x.y.z/configs/default</code> file, set the
+<code>DRM_SOURCE_PATH</code> variable to indicate where the DRM files
+are located.
+</p>
+<p>
+Now build Mesa and the DRI drivers by running
+</p>
+<pre>
+make linux-dri
+</pre>
+<p>
+There are also <code>linux-dri-x86</code>, <code>linux-dri-x86-64</code>,
+and <code>linux-ppc</code> configurations, optimized for those architectures.
+</p>
+
+<p>
+Finally, you'll need a DRI-enabled X server from
+<a href="http://freedesktop.org/wiki/Software_2fXserver" target="_parent">
+X.org</a> or <a href="http://www.xfree86.org" target="_parent">XFree86</a>.
+Visit those projects' home pages for more information.
+</p>
+
+</li>
+</ul>
+
+
+<p>
+Later, if you want to rebuild for a different configuration run
+<code>make realclean</code> before rebuilding.
+</p>
+
+
+<h3>1.2 The libraries</h3>
+
+<p>
+When compilation has finished, look in the top-level <code>lib/</code>
+directory.
+You'll see a set of library files similar to this:
+</p>

+<h3>1.3 Running the demos</h3>
+
+<p>
+If you downloaded/unpacked the MesaDemos-x.y.z.tar.gz archive or
+obtained Mesa from CVS, the <b>progs/</b> directory will contain a
+bunch of demonstration programs.
+</p>
+
+<p>
+Before running a demo, you may have to set an environment variable
+(such as <b>LD_LIBRARY_PATH</b> on Linux) to indicate where the
+libraries are located. For example:
+<p>
+<blockquote>
+<b>cd</b> into the Mesa <b>lib/</b> directory.
+<br>
+<b>setenv LD_LIBRARY_PATH ${cwd}</b> (if using csh or tcsh shell)
+<br>
+or,
+<br>
+<b>export LD_LIBRARY_PATH=${PWD}</b> (if using bash or sh shell)
+</blockquote>
+
+<p>
+Next, change to the Mesa/demos/ directory:
+</p>
+<blockquote>
+<b>cd ../progs/demos</b>
+</blockquote>
+
+<p>
+Run a demo such as gears:
+</p>
+<blockquote>
+<b>./gears</b>
+</blockquote>
+
+<p>
+If this doesn't work, try the <b>Mesa/progs/xdemos/glxinfo</b> program
+and see that it prints the expected Mesa version number.
+</p>
+
+<p>
+If you're using Linux or a similar OS, verify that the demo program is
+being linked with the proper library files:
+</p>
+<blockquote>
+<b>ldd gears</b>
+</blockquote>
+
+<p>
+You should see something like this:
+</p>
+<pre>
+ libglut.so.3 => /home/brian/Mesa/lib/libglut.so.3 (0x40013000)
+ libGLU.so.1 => /home/brian/Mesa/lib/libGLU.so.1 (0x40051000)
+ libGL.so.1 => /home/brian/Mesa/lib/libGL.so.1 (0x400e0000)
+ libc.so.6 => /lib/i686/libc.so.6 (0x42000000)
+ libm.so.6 => /lib/i686/libm.so.6 (0x403da000)
+ libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x403fc000)
+ libXmu.so.6 => /usr/X11R6/lib/libXmu.so.6 (0x404da000)
+ libXt.so.6 => /usr/X11R6/lib/libXt.so.6 (0x404f1000)
+ libXi.so.6 => /usr/X11R6/lib/libXi.so.6 (0x40543000)
+ libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0x4054b000)
+ libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x405fd000)
+ libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x40605000)
+ libpthread.so.0 => /lib/i686/libpthread.so.0 (0x40613000)
+ /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
+ libdl.so.2 => /lib/libdl.so.2 (0x40644000)
+ libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0x40647000)
+ libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0x40650000)

+<H3>1.4 Installing the header and library files</H3>
+
+<p>
+The standard location for the OpenGL header files on Unix-type systems is
+in <code>/usr/include/GL/</code>.
+The standard location for the libraries is <code>/usr/lib/</code>.
+For more information see, the
+<a href="http://oss.sgi.com/projects/ogl-sample/ABI/" target="_parent">
+Linux/OpenGL ABI specification</a>.
+</p>
+
+<p>
+If you'd like Mesa to co-exist with another implementation of OpenGL that's
+already installed, you'll have to choose different directories, like
+<code>/usr/local/include/GL/</code> and <code>/usr/local/lib/</code>.
+</p>
+
+<p>
+To install Mesa's headers and libraries, run <code>make install</code>
+You'll be prompted to enter alternative directories for the headers
+and libraries.
+</p>
+
+<p>
+Note: at runtime, you can set the LD_LIBRARY_PATH (on Linux) to switch
+between the Mesa libs and another vendor libs whenever you want.
+This is a handy way to compare multiple OpenGL implementations.
