<H2>1. Unix/X11 Compilation and Installation</H1>
<p>
Mesa uses a rather conventional Makefile system.
A GNU autoconf/automake system used to be included, but was discarded
in Mesa 5.1 because:
</p>
<ul>
<li>It seldom worked on IRIX, Solaris, AIX, etc.
<li>It was very compilicated
<li>Nobody maintained it
<li>libtool was just too weird
</ul>
<p>
If someone strongly feels that Mesa should have a autoconf/automake
system and wants to contribute one and maintain it, we'll consider
adding it again.
</p>
<p>
In Mesa 6.1 we modified the conventional Makefile system.
Instead of specifying all the various system configurations in the
Make-config file, there's a directory named <code>configs/</code> which
has an individual file for each configuration.
One of the configs gets copied to <code>configs/current</code>, which
is then included by all Makefiles.
</p>
<h3>1.1 Compilation</h3>
<p>
Note: if you've obtained Mesa through CVS, do this first:
Mesa may be compiled in several different ways:
</p>
<pre>
cd Mesa
chmod a+x bin/mklib
</pre>
<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>
Just type <b>make</b> in the top-level directory.
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>
If you want to rebuild for a different configuration run
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.
