<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 will be compiled as
a software renderer using Xlib to do all rendering.
The libGL.so library will be a self-contained rendering library that will
allow you to run OpenGL/GLX applications on any X server (regardless of
whether it supports the GLX X server extension).
You will <em>not</em> be able to use hardware 3D acceleration.
<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
accelerated OpenGL rendering (for ATI, Intel, Matrox, etc) will be built.
The libGL.so library will support the GLX extension and will load/use
the DRI hardware drivers.
<p>
<b>Prerequisites:</b>
</p>
<ol>
<li>
<p>
DRM kernel modules and header files from the
<a href="http://dri.sf.net/" target="_parent">DRI</a> project.
</p>
<p>
If you don't already have the DRM file, you can get the sources from
CVS by doing:
<pre>
cvs -z3 -d:pserver:anonymous@anoncvs.freedesktop.org:/cvs/dri co drm
</pre>
<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. Mesa
6.5 requires at least libdrm 2.0.1 or greater.
</p>
<p>
You can verify that the DRM files have been properly installed by
running <code>pkg-config --modversion libdrm</code>
</li>
<li>
Recent /usr/include/GL/glxproto.h file.
<p>You'll need this if you get any errors about _GLXvop_BindTexImageEXT
being undefined.
</p>
<p>The latest version can be
obtained from <A href="http://webcvs.freedesktop.org/*checkout*/xorg/proto/GL/glxproto.h?rev=1.9&content-type=text%2Fplain">freedesktop.org CVS</a>
</p>
</li>
<li>DRI-enabled X server.
<p>Visit
<a href="http://www.xfree86.org" target="_parent">XFree86</a>
or
<a href="http://freedesktop.org/wiki/Software_2fXserver" target="_parent">
X.org</a>
for more information.
</p>
</li>
</ol>
<p>
Build Mesa and the DRI hardware 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 which are optimized for those
architectures.
</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>
(or <code>lib64/</code>) directory.
You'll see a set of library files similar to this:

<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)

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)

<p>
Retrace your steps if this doesn't look right.
</p>
<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>.
But first, check the Mesa/configs/default file and examine the values
of the <b>INSTALL_DIR</b> and <b>DRI_DRIVER_INSTALL_DIR</b> variables.
Change them if needed, then run <code>make install</code>
</p>
<p>
Note: at runtime you can use the LD_LIBRARY_PATH environment variable
(on Linux at least) to switch
between the Mesa libraries and other vendor's libraries whenever you want.
This is a handy way to compare multiple OpenGL implementations.
