<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>
|
|
For Mesa 7.0.2 <a href="http://dri.freedesktop.org/libdrm/">
|
|
DRM version 2.3</a> is required.
|
|
</p>
|
|
<p>
|
|
To check if you already have it, run:
|
|
<br>
|
|
<code>pkg-config --modversion libdrm</code>
|
|
</p>
|
|
<p>
|
|
You can download and install a <a href="http://dri.freedesktop.org/libdrm/">
|
|
tarball release</a> or get the code from git with:
|
|
<br>
|
|
<code>git clone git://anongit.freedesktop.org/git/mesa/drm</code>
|
|
<br>
|
|
Then revert to the drm-2.3.0 tag with:
|
|
<br>
|
|
<code>git-reset --hard drm-2.3.0</code>
|
|
</p>
|
|
</li>
|
|
|
|
<li>
|
|
Relatively recent
|
|
<a href="http://freedesktop.org/wiki/Software_2fXserver" target="_parent">
|
|
X.org</a> release.
|
|
Mesa depends on a number of X header and library files.
|
|
</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:

<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>
|
|
The variable
|
|
<b>DESTDIR</b> may also be used to install the contents to a temporary
|
|
staging directory.
|
|
This can be useful for package management.
|
|
For example: <code>make install DESTDIR=/somepath/</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.
|
|
</p>
|
|
|
|
|
|
<H3>1.5 pkg-config support</H3>
|
|
|
|
<p>
|
|
Running <code>make install</code> will install package configuration files
|
|
for the pkg-config utility.
|
|
</p>
|
|
|
|
<p>
|
|
When compiling your OpenGL application you can use pkg-config to determine
|
|
the proper compiler and linker flags.
|
|
</p>
|
|
|
|
<p>
|
|
For example, compiling and linking a GLUT application can be done with:
|
|
</p>
|
|
<pre>
|
|
gcc `pkg-config --cflags --libs glut` mydemo.c -o mydemo
|
|
